The purpose of this study is to explore the effectiveness of Cfr-PEEK, in the fixation of unfavorable fractures of mandibular angulus by comparing it with the titanium and resorbable biomaterials. 8 different fixation models were created. In the first 4 groups, a single mini plate was applied to the upper edge of the fracture line by the Champy method. In the other 4 groups, an additional plate was placed on the lower edge of the fracture line. In these models, titanium, resorbable and Cfr-PEEK plate/screw systems were investigated by the finite element analysis method. The highest Von Mises stress was observed on the upper plate in the group 5 while the lowest was seen in the lower plate in the group 7. The highest stress values on the screws were observed on the screws placed closer to the fracture line. Considering the stresses on the bone around the screws, the highest Pmax and Pmin values were seen in group 5, and the lowest values were seen in the group 7. The highest displacement was observed in the group 3, while the lowest was observed in the group 5. According to the results it can be said that Cfr-PEEK plate/screw systems may provide advantages by decreasing the stresses on the fixation systems over the titanium plates and providing more stable fixation over the resorbable systems. Cfr-PEEK plates of 2 mm thickness seems to be a potential alternative to 1 mm thick titanium plates.

AMAÇ 2019 yılı sonlarında Çin Halk Cumhuriyeti’nin Wuhan eyaletinde diş hekimliği uygulamalarını da önemli ölçüde etkileyen pnömoni salgını görülmüştür. Salgının 2020 yılında hızla küresel ölçekte yayılmasıyla beraber Dünya Sağlık Örgütü (DSÖ) tarafından pandemi ilan edilmiştir. Sağlık hizmetine ihtiyacın arttığı pandemi döneminde, sağlık merkezleri bulaş riskine açık yerler haline geldiğinden elektif işlemler ertelenmiş, sağlık merkezleri pandemi koşullarına uygun şekilde çalışmaya başlamıştır. Özellikle diş hekimliği; aerosol oluşumu ve yakın temas nedeniyle yüksek bulaş riskiyle karşı karşıya olan meslek grubu olarak dikkat çekmektedir.

This review aimed to assess the current evidence on the diagnostic potential of saliva regarding the detection of coronavirus disease 2019 (COVID-19). The literature published until May 24, 2020 was searched in the Web of Science, PubMed and Google Scholar databases with the keywords "COVID-19", "SARS-CoV-2", "2019-nCoV", "oral fluid", "saliva", and "diagnosis", individually and in combination, and 11 studies that explored the efficacy of saliva in the diagnosis of COVID-19 in different patient groups were found. Together, these studies suggest that saliva is a safe and reliable tool for the diagnosis of COVID-19. Further, saliva offers enhanced safety as well as logistical and economic benefits as compared to the current methods used to diagnose COVID-19. However, there is still limited evidence in the literature to make a definitive, clinically appropriate decision. The ideal specimen for the detection of acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still an issue under investigation. Thus, new studies with large sample sets for the validation of easy, safe and reliable methods applicable for large-scale testing are immediately required.

Objective: The aim of this study is to explore the feasibility and acceptability of teledentistry as a vehicle that provides enhanced delivery of oral care for the people who need special care (PNSC). Methods: Between January 2018 and September 2020, PNSC who were admitted in the study were either waiting for a follow-up (F) appointment or on a waiting list. An examination via video call was carried out for initial examination (IE) and F purposes. The virtual examination was scored by the clinician who performed the examinations. The experience of the participants was evaluated with a satisfaction questionnaire. Results: Forty PNSC (26 females, 14 males) between ages 7 and 48 years (21.17 ± 10.62) participated in the study. According to the clinician ratings, the accuracy of the examination was rated as the lowest. The F group had higher scores when compared to the IE group regarding clinician rating. No significant differences were found in terms of the scoring of the clinician and patient/parent satisfaction regarding cooperation status and type of examination (P ≥ 0.05). Conclusions: Through adequate adaptation of the technology into clinical practice and overcoming the barriers for wider implementation, the teledentistry approach could be a reliable and feasible alternative in triaging, treatment planning, and F purposes for PNSC.

Background: The aim of this study was to investigate the effects of concentrated growth factors (CGF) and advanced platelet-rich fibrin (A-PRF) on edema, pain, and trismus after mandibular third molar surgery. Material and Methods: Patients were randomly divided into A-PRF, CGF and control groups. After extraction of the third molars, A-PRF and CGF were prepared and applied to the extraction sockets in study groups, while nothing was applied to the control group. Edema was measured from 5 reference points including tragus, labial commissure, soft tissue pogonion, lateral corner of the eye/lateral canthus and angulus mandible. Trismus measured as the distance between the right lower and upper right central incisors. Trismus and edema were measured preoperatively, and on postoperative 2nd and 7th days. Pain evaluated using the visual analogue scale (VAS) between 6th hour and 7th day after surgery. Results: A total of 75 patients, 25 in each group, were included in the study. The change in tragus to labial commissure measurements showed a significant difference between baseline-7th days among control and CGF groups (P= 0.038). Significant differences observed between the tragus to pogonion measurements at baseline-7th days among the control-CGF groups (P= 0.014), and A-PRF-CGF groups (P = 0.038). Secondary outcome variables trismus, pain, and analgesic consumption showed no significant differences among the groups (P > 0.05). Conclusions: Based on the results of this study it can be concluded that A-PRF and CGF seem to have no positive effects on pain, edema, and trismus after third molar surgery. Abbreviations: A-PRF, advanced platelet-rich fibrin; CGF, concentrated growth factors.

Dentists are vulnerable to occupational injuries associated with dental procedures, and to their work environment. Lack of appropriate and safe working conditions can put dental professionals at risk of injuries, the majority of which are musculoskeletal, especially in the wrist. This report presents a case of a radial crack in the wrist of a dental student which occurred as a complication of a tooth extraction procedure. Also, emphasises the need for education about workplace risks and hazards, starting at the undergraduate level, to promote prevention of occupational injuries.

Due to the special circumstances and the pre-natal environment in twin gestations, disruptions in the development of the embryo are more frequently observed in twin births as compared to singleton births. Twin research provides an excellent model to explore the etiology of disruptions in craniofacial biology. Mirror imaging (MI) is a special manifestation of twinning, and the elucidation of the etiology of this phenomenon is important to understand the biological mechanisms which underlie congenital defects, like orofacial clefts, and to provide insight into left-right asymmetry. The aim of this paper was, therefore, to present 3 pairs of Turkish monozygotic (MZ) twins with MI dental features, and to contribute to the knowledge of the MI phenomenon in the literature. We examined 2 male and 1 female MZ twin pairs clinically and radiographically in terms of their MI features. Mirrorimage features in dental and other ectodermal structures were detected in all the twins. Understanding the biological mechanisms of MI provides broad insight into preventive measures and treatment protocols. Furthermore, the presence of MI features may lead to the detection of other MI pathologies in twins.

WOS: 000532698500016 Adenomatoid odontogenic tumor is a rarely seen nonaggressive tumor originated from the remnants of dental lamina. Majority of the cases detected in females with a peak incidence at the second decade of life. Adenomatoid odontogenic tumor is most commonly detected in the anterior region of the maxilla and occurrence of the tumor in mandible is rarely seen. The aim of this case report is to present the diagnosis and treatment of a rare case of adenomatoid odontogenic tumor located in the anterior region of the mandible of a 68-year-old edentulous man.

The aim of the present study was to evaluate the facial esthetic perception of dental students, non-dental students, and laypersons with respect to digitally altered profile photographs in the vertical and sagittal dimensions.Colored profile photographs of a male subject and a female subject were digitally altered in the sagittal and vertical dimensions. Preclinical and clinical dental students, clinical medical students, senior art and engineering students, and laypersons with various occupations were invited to rate the profile photographs and their treatment need by means of a questionnaire created on Google Forms.The study involved 574 participants (378 females, 196 males). Male and female straight normal profiles were found to be the most attractive facial profiles by all groups, followed by convex profiles. Concave profiles were rated as the least attractive and in need of more treatment. No significant difference was observed between the ratings of the preclinical and clinical dental students. The ratings of dental students showed significant differences in terms of esthetic perception compared with the engineering students and laypersons. Regarding the gender of the participants, there were significant differences between males and females.The perception of facial esthetics was influenced by education, and students whose study curriculum was esthetic in nature or clinically based were more critical in their judgment. The gender of the participants significantly influenced their esthetic judgment.

PURPOSE The aim of this retrospective study was to evaluate the clinical performance of two implants supporting mandibular overdentures by means of clinical and radiologic parameters, and also to explore the relationship of marginal bone loss with implant-/patient-related factors and soft tissue parameters. MATERIALS AND METHODS Data of patients who had undergone insertion of two implants into the interforaminal region between November 2012 and December 2016 using three different implant systems were retrieved from the archival records. Age, sex, implant length, implant diameter, observation period, mobility, and soft tissue parameters were recorded. Marginal bone levels and interimplant distances were measured with computer software on panoramic radiographs obtained at 3 months and at the recall session. RESULTS A total of 43 patients with 86 implants were included in the study. Patients were evaluated with an average observation period of 41.79 months. Among the evaluated parameters, Gingival Index, Bleeding Index, and implant diameter were found to have significant effects on the marginal bone loss (P < .05). However, no significant effects of sex, age, implant length, observation period, and interimplant distance were observed on the marginal bone loss. No implants showed peri-implantitis or mobility, while eight implants showed peri-implant mucositis. CONCLUSION Within the limitations of this study, it can be concluded that peri-implant soft tissue health and the diameter of the implant have an important effect on the marginal bone loss as well as the success of two-implant-supported mandibular overdentures.

Maxillary transversal deficiency (MTD) is a common skeletal problem. If not treated on time, MTD evolve to a more complex malocclusion. This problem can affect facial growth and development. Rapid maxillary expansion (RME) procedure frequently used for the management. This technique is usually successful in young individuals but as the age advances and the articulations of the maxilla with surrounding facial bones get more rigid, it becomes ineffective. Undesirable side effects or results have been reported after use of RME in skeletally mature patients such as buccal tipping of posterior teeth, extrusion, periodontal tissue recession, fenestration of buccal cortex, necrosis of palatal tissue, failure in opening of midpalatal suture, pain, and relapse of expansion. Side effects of RME are often temporary and permanent damages are rarely seen. The aim of this report is to present the management of a permanent side effect of the RME procedure in a 13-year-old child.

Metastasis from the prostate gland to the mandible is rarely encountered and commonly present with non-specific features like unexplained pain, swelling, and numb chin syndrome. Here we present a case with metastatic prostate adenocarcinoma detected secondary to oral manifestations. Patients present with unexplained facial pain and numbness should alert clinicians to the presence of malignant disease, and appropriate hematological, radiological and or histological investigations should be performed. Thereby, clinicians can prevent the overlook of the first signs of metastasis, accelerate the early diagnosis and positively orientate the prognosis of the disease, especially in a patient without known malignancy.

Purpose To explore the feasibility and diagnostic accuracy of the tele-dentistry for the follow-up of different diagnostic groups of Turkish patients in maxillofacial surgery. Materials and Methods In this study, follow-up patients were allocated to four groups as dental implant, minor surgical procedure, infection-medication-related osteonecrosis of the jaws (MRONJ) and temporomandibular joint disorder (TMD). In all groups, remote examination via video call and subsequently face-to-face clinic examination were performed. The quality and accuracy of the video call were scored by the same investigator. Also, patient satisfaction regarding the video call was evaluated with a questionnaire. Results Twenty-one patients (12 females, 9 males) between 18 and 71 years (38.90 ± 17.88) participated in the study. A strong preference of 71% and 95% toward video call by patients was seen in the questionnaires performed after video call and face-to-face examination, respectively. Regarding the rating of the clinician, no significant differences were found between groups in terms of the quality and accuracy of video call (p ≥ 0.05). Conclusion Remote follow up of diagnostic groups which can benefit from tele-dentistry pose a promising remedy that is reliable as in-person visits and also can reduce the clinical visits in routine clinical practice.

Background The purpose of this study was to explore the effects of coronavirus disease 19 (Covid-19) on the oral cavity by evaluating the oral findings in the patients who recovered after treatment. Material and Methods This study involved confirmed Covid-19 patients whose treatment completed at least two weeks ago. A questionnaire consist of eight parts was applied to explore the oral findings after Covid-19. Also stimulated salivary flow rate was evaluated with a salivary flow test. Results 177 patients reached and 107 of them participate in the study. Regarding gender significant differences were found in terms of the presence of taste impairment after treatment (p=0.007), the degree of taste (p=0.021) and smell (p=0.010) impairment. 18 % (5/27) of the patients evaluated were showed hyposalivation. No significant differences were observed regarding salivary flow between males (mean±SD: 1.14±0.65) and females (mean±SD: 1.12±0.43), (p=0.928); among the patients having treatment at home (mean±SD: 1.03±0.48) or hospital (mean±SD: 1.33±0.65), (p=0.187). In some of the patients’ taste [15], smell [23] impairment, and xerostomia [43] still observed at least two weeks after the treatment is completed. Conclusions The most frequent finding in patients after the treatment was xerostomia. Taste and smell impairments were more frequently observed in females. Key words:Saliva, oral findings, hyposalivation, Covid-19.

The aim of this retrospective study was to compare the effectiveness of hyaluronic acid (HA) and injectable platelet-rich fibrin (i-PRF) in the management of Wilkes stage III internal derangement, and to evaluate the biosupplementation capacity of i-PRF. The records of all 54 relevant patients with Wilkes stage III internal derangement confirmed by magnetic resonance imaging and treated with arthrocentesis alone or in combination with HA or i-PRF were selected. The outcome variables were pain intensity at rest (VASr) and in function (VASf), evaluated with a visual analogue scale, and maximum mouth opening (MMO), evaluated in millimetres; assessments were made preoperatively, immediately after the procedure, and at 1 week, 1 month, and 3 months postoperatively. When compared to the HA and arthrocentesis groups, the i-PRF group showed significantly better improvements in MMO at 1 and 3 months (P=0.024 and P=0.006, respectively), VASr at 1 and 3 months (both P

Sialolithiasis is described as the existence of calcified structures in ducts of salivary glands and is the most widespread disease of the salivary glands. 80-95 % of sialoliths occur at the submandibular salivary gland.

Sialoliths may be diagnosed with clinical examination, conventional radiography, computed tomography and ultrasonography. Common clinical signs in cases of sialoliths include painless swelling, large swelling often accompanied by trismus associated with eating, symptoms ranging from moderate discomfort to severe pain. In this case report clinical, radiological signs and surgical therapy of salivary stone in the submandibular gland is represented.

Amaç: Bu çalışmanın amacı, poliüretan kafatası modellerinde Le Fort I osteotomisi sonrası beş farklı plak-vida sisteminin stabilite üzerindeki etkisini araştırmaktır. Ayrıca ikincil olarak mikro ve rezorbe olabilen fiksasyon sistemlerinin özellikle kasların kısmen ince olduğu bölgelerde yeterli stabilite sağlanmasındaki etkinliğini değerlendirmeyi amaçladık.Gereç ve Yöntemler: Poliüretan kafataslarında yapay olarak oluşturulan Le Fort I osteotomisinin sabit fiksasyonu için standart titanyum mini plaklar, titanyum mikroplaklar ve rezorbe olabilen plakalar uygulandı. Isırma kuvvetlerini simüle etmek için aşağı-yukarı yönde yük uygulandı. Kuvvet-yer değiştirme değerleri kaydedildi.Bulgular: 120, 150, 180 ve 200 N yüklemede beş farklı fiksasyon sisteminin yer değiştirme değerleri arasında önemli farklılıklar gözlendi (p, Background: The aim of this study is to explore the effect of five different plate-screw systems on the stability after LeFort I osteotomy in polyurethane skull models. Also, we aimed secondarily to evaluate the efficiency of the use of micro and bioabsorbable fixation systems especially in the regions where the muscularity is relatively thin, in providing enough stability.Methods: Standard titanium miniplates, titanium microplates and bioabsorbable plates were applied for the internal fixation of artificially created LeFort I osteotomy on polyurethane skulls. Load applied in inferior-superior direction to simulate bite forces. The load-displacement values were recorded.Results: Significant differences were observed among the displacement values of five fixation systems at 120, 150, 180 and 200 N of loading (p< 0.05). The highest displacement values were observed in the 4RLt-Micro group with the increasing load. The 4RLt-Mini and 4LLt-Mini groups showed the least displacement values, and the 4LLt-Mini group showed less displacement than the 4RLt-Mini group. The 2Lt/2It- Mini and 2Lt/2Ir-Mini groups showed proximate displacement values with the 4RLt-Mini and 4LLt-Mini groups.Conclusions: The results of this study show that the left sided L miniplates provide more stable results than the right sided ones. Also, it may be said that while sufficient stability can be obtained, the problem of palpability is also eliminated with the use of bioabsorbable plates in the regions with thin muscularity in combination with standard titanium miniplates. However, further in vitro and in vivo studies with wider advancement values needs to be conducted to confirm these results.

Objectives: The purpose of this study was to explore the contribution of the genetics and the environment on the mandibular morphology of the Turkish twins.Materials and Methods: This retrospective study conducted with the archival records of the twins who have applied between 2012 and 2018.Condylar height, ramus height, gonial angle, intercondylar distance and intergonial distance were measured on the panoramic radiographs with computer software. The correlations between the monozygotic (MZ) and dizygotic (DZ) twins, and heritability estimates were evaluated.Results: Moderate to high heritability observed in condylar height, ramus height, intercondylar distance and left gonial angle. Low heritability observed in intergonial distance and right gonial angle. Similar intra-pair correlations were found within the MZ and DZ male and female twin pairs for the measured parameters. However, no significant correlations observed within the DZ opposite sex twins. No significant difference also observed within the MZ male and female twin pairs in terms of the measured parameters except the significant difference in right ramus height of male MZ twins.Conclusion: Horizontal parameters were found to be more susceptible to environmental factors then vertical ones. Gender was found to be caused similar variability in the measured parameters. Beside the results of the present study, it should be considered that the heritability is a concept that related with population rather than an individual, it would not be correct to reach definitive conclusions regarding the prevention of the disruptions, and prognosis of the treatments. Thus, the results should be interpreted cautiously when they are transformed into the clinical applications.Keywords: Heritability, twin study, mandibleGENETİK VE ÇEVRENİN MANDİBULAR MORFOLOJİYEKATKISININKLASİKİKİZ YÖNTEMİ İLE ARAŞTIRILMASIÖZETAmaç: Bu çalışmanın amacı, genetik ve çevrenin, Türk ikizlerinin mandibular morfolojisine katkısını araştırmaktır.Gereç ve Yöntem: Bu retrospektif çalışma 2012 ve 2018 yılları arasında başvuruda bulunan ikizlerin arşiv kayıtları ile yapılmıştır.

Background/Aim: Residual cysts comprise approximately 10% of all odontogenic cysts. They are more commonly seen in 4th-6th decades of life, and occur due to incomplete previous surgical removal of a radicular cyst; or due to left epithelial remnants stimulated by tooth extraction. These lesions are often treated with enucleation. However, this procedure is not always the ideal treatment solution for elderly people due to the presence of physical and mental disorders, and risk of jaw fracture. Case Report: In this case report, the successful treatment of a large residual cyst in the symphysis of a 93 year-old female patient by performing decompression alone is presented. A plastic drain was placed on the wall of the cyst to allow irrigation. Regeneration was observed in the cyst cavity 3 months after surgery. The 1-year follow up showed that the majority of the cyst cavity was filled with new bone. Conclusions: In elderly patients, large inflammatory cysts can be successfully treated with decompression considering the limited regeneration capacity and difficulties in follow-up.

Accidental displacement of the third molar tooth or its fragment into the anatomical spaces is a rare but potentially serious complication. The most common sites of mandibular third molar displacement are the sublingual, submandibular, and pterygomandibular spaces. Removal of a displaced tooth or its fragments from these spaces may be difficult due to poor access and the vital structures involved in these spaces; therefore, removal may result in permanent damage. This article is intended to provide a concise update of the reported cases of submandibular displacement and to present a case of intraoral management of mandibular third molar root fragments that were displaced into the submandibular space.

Aspergillosis is a fungal infection mainly affects the nasal cavity and paranasal sinuses in maxillofacial region. Aspergillus infection can be seen in three clinical forms as non-invasive, invasive and allergic. The non-invasive form of aspergillus also called as aspergillus mycetoma, aspergilloma or fungus ball, commonly seen in healthy individuals. Maxillary sinus aspergilloma may occur after treatments of antral teeth. Although usually asymptomatic maxillary sinus aspergilloma in some instance may exhibit clinical symptoms such as swelling, purulent discharge, chronic sinus pain, nasal congestion, headache which are similar to the other sinus infections in symptomatic patients. This case report presents the diagnosis and surgical management of maxillary sinus aspergillus infection that occurs after tooth extraction.

The extraction of third molar teeth has usually been associated with a high level of anxiety, mainly from a lack of knowledge. We compared the effect of different informed consent formats on the perioperative anxiety level of patients scheduled for third molar surgery and explored the effects of watching a video about the surgical procedure from the Internet before the procedure on the patients' anxiety level.A total of 113 patients who had been admitted for the removal of impacted third molars were randomly divided into control (verbal information) and study (video plus verbal information) groups. The anxiety level was assessed using the Amsterdam Preoperative Anxiety and Information Scale, Modified Dental Anxiety Scale, and Spielberger's State-Trait Anxiety Inventory. Pain was evaluated using the visual analog scale (VAS).The results showed that the study group had higher anxiety scores than the control group immediately after the consent process (P .05). In all groups, the anxiety levels showed a decreasing trend after surgery. The VAS scores did not show significant differences when stratified by gender or educational level. No correlation was observed between age and the other variables.According to our results, the patients who watched the procedural video in an uncontrolled situation from websites before the operation were prone to high anxiety. The verbal and written consent format resulted in satisfactory anxiety management. Further studies are needed to clarify whether the use of video consent with different formats, such as animation, would be more effective in managing anxiety when applied carefully and under the control of a clinician.

Aim: Genetic variations contribute differences in defensive behaviors among individuals. However, the exact role of heritability in the etiology of defensive behaviors like dental anxiety is not elucidated clearly. Twin studies provide an excellent source to investigate the relative contribution of genetics and environment in various phenotypic traits or disorders. Therefore, the aim of this study is to explore the relative contribution of genetics on dental anxiety on Turkish twins by using the classical twin method. Material and Methods: Corah’s Dental Anxiety Scale used for the anxiety measurement of 70 pairs of Turkish twins. Decayed, Missing, Filled-Teeth (DMF-T) index was calculated according to the number of decayed, missing and filled teeth after clinical and radiological examinations.Results: No significant differences and correlations found within the dental anxiety scores of Monozygotic (MZ) and Dizygotic (DZ) twin-pairs. Significant positive correlation for DMF-T scores was found within the MZ and DZ twin-pairs.Conclusion: Based on the data obtained from our study, it can be concluded that environmental factor appears to have a more dominant effect on dental anxiety and the high correlation regarding DMF-T among MZ twin pairs indirectly shows the genetic effect on dental caries.

WOS: 000502570500002 Odontomas can be detected as complex or compound variants and they rarely show the histologic characteristics of both types together. The tumor commonly associated with malocclusion, eruption disturbances and pathological anomalies, but they seldom cause bony expansion. Early detection and management of odontoma with multidisciplinary approach pose an important role to prevent disturbances associated with this common odontogenic tumor. Here we report a rare case of an odontoma which show the features of both complex and compound types and also cause bony expansion, eruption failure in an 8-year-old boy.

Osteoma is a benign osteogenic neoplasm originating from the continuous proliferation of compact and/or cancellous mature bone. The tumor can be classified as peripheral, central or extra-skeletal regarding location and it commonly seen in the cranio-facial region especially at the skull and paranasal sinuses. The exact etiology of the tumor is still controversial; however, it is considered that infection, trauma, muscle activity contributes the occurrence of the tumor. Due to the slow growing nature of osteoma, it is coincidentally detected on radiographs or when the tumor reaches a large size enough to trigger symptoms and cause facial disfigurement. Although mainly detected in the craniofacial bones, osteomas are rarely located in the jaw bones. The purpose of this review, is to present the diagnosis and treatment plan of a peripheral osteoma in the mandibular angulus region of an 8-year-old boy together with a review of published cases of peripheral osteomas of mandibular angulus.

The aim of this report is to present an unusual case of a dental implant that displaced into the mandibular canal and to highlight the importance of adequate preoperative planning and surgical knowledge.

Torul, Damla/0000-0003-2323-606X WOS: 000439703500033 PubMed: 29763577 Purpose: The aim of this study was to investigate the effects of platelet-rich fibrin (PRF) and plasma rich in growth factors (PRGF) on peripheral nerve injury in the early period of healing. Material and Methods: Thirty Wistar albino rats were used in this study. Rats were divided into control (C), damaged (D), PRF, and PRGF groups. The left sciatic nerves of each group were identified as group C. Crush-type injury was performed on the right sciatic nerves of the D, PRF, and PRGF groups. In the PRF and PRGF groups, blood 2 mL was obtained to prepare the PRF and PRGF and the biomaterials were applied to the injured nerve area. After 8 weeks, functional, electrophysiologic, and stereological evaluations were performed. Results: For the electrophysiologic evaluation, the latency and amplitude values in the D, PRF, and PRGF groups were significantly lower than those in the C group (P>.05). According to the sciatic functional index result, there were significant differences between groups D and PRF and between groups D and PRGF (P=.000). For the stereological evaluations, although no significant difference was observed between the PRGF and C groups (P>.05), a significant difference was observed among the D, PRF, and PRGF groups for myelinated axon number. There were significant differences between groups D and PRF and between groups D and PRGF for axon area (P=.021 and .001, respectively). No significant difference was observed among the D, PRF, and PRGF groups for myelin sheath thickness and ratio of axon area to myelin sheath thickness (P>.05). Conclusions: The results of this study suggest that PRGF increases nerve regeneration in the early period of healing and that the limited early action of PRF should be re-evaluated in the late period.

Tissue necrosis associated with local anesthesia and actinomycosis is rare. Here, the authors present management of excessive palatal necrosis associated with local anesthesia and actinomycotic infection. In oral surgery a simple procedure can lead to severe complications. Thus, preformation of any surgical procedure with a rigorous manner preferably by a qualified clinician may prevent the occurrence of this type of complications.

The aim of this study was to determine the frequency and etiology of maxillary sinus retention cysts (RCs) in a Turkish patient population in the Middle Black Sea region by using panoramic radiography. We retrospectively reviewed 9,659 panoramic radiographs that were taken from March 2012 to January 2014. The number, location, and the size of the RCs as well as the age, gender, dental status, and radiographic dental findings of the patients were recorded. Of the 9,659 patients, 158 had RCs with a frequency of 1.6 %. Male patients had significantly more RCs than female patients did (p

WOS: 000506577700011 PubMed: 31607728 Objective: The aim of this study was to compare the efficacy of hyaluronic acid (HA) and xenografts on the repair of peri-implant dehiscence-type bone defects occur during implant placement. Patients and Methods: Forty-two dehiscence Class I type defects located on the buccal surface of the implants were included in this study. Defects were divided into two main groups as small sized (height of 0.05). Reduction in VBH was observed up to 6-12 months after prosthetic loading in all defect sites. This reduction was found statistically significant in medium-sized defects that grafted with XC (P < 0.05, paired t-test). However, in other subgroups, the difference between measurements at 6(th) and 12(th) months was not statistically significant (P > 0.05). Conclusions: According to the data obtained from this study, it can be concluded that HA did not have a significant positive effect on the repair of defects around dental implants.

Aspergilloma of the maxillary sinus is considered rare in immunocompetent patients, but a considerable increase has recently been seen in the incidence of reported cases. Dental procedures involving the antral region are thought to predispose individuals to this form of aspergillosis. Because aspergilloma shares similar clinical features with other sinus pathologies, its diagnosis may be delayed. Thus, an early diagnosis confirmed by a histopathological examination plays a crucial role in the adequate management of aspergilloma. This article provides a concise review of the reported cases of aspergilloma associated with dental procedures and reports 2 new cases of aspergilloma in middle-aged female patients, with a presentation of their cone-beam computed tomographic findings.

Background and Aims: The aim of this study was to compare the biomechanical stability of poly‑L‑lactic acid and titanium screws in the fixation of intracapsular condylar fractures, in 10 polyurethane hemimandibles.Materials and Methods: Artificial intracapsular fractures were created with a steel disk and electronic micromotor. The first group was fixed with 15 mm long self‑tapping 2.0 mm system titanium screws and the second group was fixed with 15 mm long 2.4 mm bioresorbable screws. Linear loads of 25, 50, 75, 100 N was applied in anteroposterior direction to the hemimandibles and the data were transmitted directly from the load cell to a computer that shows emergent results of material characteristics under same forces as a graphic containing force and displacement.Results: The results show that there were no significant differences between the two methods, with 25 N of loading. (P > 0,05) The difference became significant with a higher value of loading.Conclusion: The results suggest that treatment with a single resorbable screw is not functionally stable as a single titanium screw.Key words: Intracapsular condylar fractures, osteosynthesis, screw fixation

Objective: Foreign bodies can be deposited in the oral cavity either by traumatic or iatrogenic injury. The most common foreign bodies of iatrogenic origin encountered are restorative materials, like amalgam, and root canal fillings. The aim of this study was to determine the prevalence of foreign bodies detected with panoramic radiography in the jawbones, as well as to evaluate the etiology and characteristics of these pathologies. Materials and Methods: From March 2012 to January 2014, 11,144 panoramic radiographs were taken and retrospectively reviewed. The number, characteristics, location of the foreign bodies, age, and gender of the patients were recorded. Results: Of the 11,144 patients reviewed, 62 of them have a foreign body with a frequency of 0.6%. The patients who had a foreign body were between 14 and 81 years old. Female patients showed more foreign bodies than male patients. Among the 62 patients, 63 filling materials, one stapler, and five shrapnel were detected. Only 8 patients had symptoms associated with foreign bodies and these foreign bodies excised surgically. Conclusion: If possible, these pathologies must be removed at the time of detection to prevent further complications; however, in asymptomatic cases, according to location and the characteristic of the foreign body, they can be kept under observation without performing any operations.
