Background/Aim. Oral health is an integral part of general health and an important factor in the overall quality of life. The purpose of this study was to investigate the prevalence of dental caries among the children from the SOS Children?s Village in Croatia. Methods. The dental examinations based on the World Health Organization criteria were performed on 88 children from SOS Children?s Village in Croatia. The teeth were clinically examined with standard dental instruments using the visual-tactile method under standard light. The clinical indexes of decayed, missed, and filled (dmft and DMFT, for primary and permantnt teeth, respectively) and decayed, missed, and filled surfaces (DMFS), as well as the significant caries index (SiC) were recorded. Results. Among the children from the SOS Children?s Village caries incidence were 57.94%. The mean dmft, DMFT and DMFS of all children was 1.82, 1.90 and 2.82, respectively. The highest mean dmft and DMFT score of 4.24 and 2.56 was found among 7?10 and 11?14 years old children, respectively. The highest mean DMFS score of 3.85 and 3.90 was found among 11?14 years old children and among the children from the SOS Children?s Village Lekenik, respectively. Among all children, the SiC index was 4.69. There was a significant difference between age groups and children?s place of residence in DMFT, DMFS and SiC. Conclusion. Prevalence of dental caries is low among the children from the SOS Children?s Village in Croatia compared to the children who lived with biological families.

After tooth extraction, the alveolar ridge undergoes dimensional changes. Different bone regeneration biomaterials are used to reduce bone loss. The aim of this article was to systematically review the literature on the effect of injectable synthetic biomaterials and their advantages and disadvantages for new bone formation in the maxilla and mandible in animals and humans. A literature search was conducted in November 2020 via MEDLINE PubMed, Cochrane, and Embase. Of the 501 records screened, abstract analysis was performed on 49 articles, resulting in 21 studies that met the inclusion criteria. Animal studies have shown heterogeneity in terms of animal models, follow-up time, composition of the injectable biomaterial, and different outcome variables such as bone–implant contact, newly formed bone, and peri-implant bone density. Heterogeneity has also been demonstrated by human studies. The following outcomes were observed: newly formed bone, connective tissue, residual injectable bone graft substitute, radiographic density, residual bone height, and different follow-up periods. Further studies, especially in humans, based on the histological and biomechanical properties of the injectable delivery form, are needed to draw more concrete conclusions that will contribute to a better understanding of the benefits of this type of biomaterials and their role in bone regeneration.

The aim of this study was to detect molar&ndash, incisor hypomineralization (MIH) and caries prevalence in eight-year-old children with early mixed dentition in Eastern Croatia. There is a lack of data on MIH in Croatia. There were 729 children examined in total: 356 (48.83%) were female and 373 (51.16%) were male. The presence of MIH was found in 95 children, the prevalence of MIH was 13%, and the remaining 634 (87%) did not have any changes associated with MIH. The prevalence of caries overall in the population of examined children was 11.48%. In the group of children with MIH, the prevalence of caries was 24.14%, while in the group of children with no MIH, the prevalence of caries was 11.18%. Teeth had a Decayed, Missing, and Filled Teeth (DMFT) index of 1.2, the value of the SiC index was 1.4, and the decayed, missing, and filled teeth (dmft) index for deciduous teeth was 5.8. Children with MIH had a caries index of DMFT 2.1, and the value of the SiC index was 2.6. The index of caries for non-MIH children was DMFT 1.1 and the SiC index was 1.2. MIH prevalence in Croatia is more common in girls than in boys. MIH has a significant impact on children&rsquo, s development and is a major factor in the occurrence of caries.

Aim of the study: The objective of the research is to examine the frequency of interdisciplinary collaboration of orthodontists and other dental specialists as well as to determine which specialty is mostly collaborated with during the therapeutic process. Material and methods: The data, that was collected and analyzed, were 586 orthopantomograms (OPGs). The patients were both male and female from 10 to 42 years old. The corpus was collected randomly during March and April of the academic year 2015/2016. After gathering the OPGs, they were analyzed in terms of whether there was potential need for interdisciplinary collaboration with different specialist branches or not. The data were analyzed using the software „MS Excell“. Results: The results showed that out of 586 OPGs, 98 patients (16.72%) needed interdisciplinary collaboration. Out of these 98 OPGs most of them, i.e. 47, 96% of cases needed collaboration with oral surgeon, after that comes prosthodontist with 25, 51%, then restorative dentist with 14, 29%, and last periodontologist with 12, 24% of cases. As oral surgery was the most frequently collaborated branch, these cases were analyzed in more depth. Conclusion: The results and literature overview corroborate the hypothesis that there is frequent need for interdisciplinary collaboration during the treatment of orthodontic patients. The results show that an oral surgeon is the most collaborated specialist during the therapeutic process. Further research with a larger sample and separation of patients by age and gender is necessary in order to obtain a full overview of the problems of interdisciplinary collaboration in orthodontics .

Background and objective: Injectable synthetic bone grafts (ISBG) are widely used biomaterials for regeneration purposes. The aim of this case report was to examine the efficacy of ISBG in the management of buccal fenestration in the case of a 25-year-old female. Case report: After a traumatic tooth extraction, the defect was filled with ISBG and covered with a resorbable membrane. The ISBG showed easy handling and the patient had no complications during healing. Six months after augmentation, a bone biopsy was taken during implant bed preparation. The histological results showed good integration of ISBG into the newly formed bone and no signs of tissue inflammation. Additionally, a CBCT (cone beam computed tomography) analysis was performed to support the histological results. Conclusion: The use of the examined ISBG led to successful treatment of the buccal fenestration defect.

The purpose of this study was to evaluate the knowledge regarding tooth avulsion and dental first aid response among Croatian students of the Faculty of Education. A cross-sectional study was conducted among students. Participants (N = 235) were female with an average age of 21.9 &plusmn, 2.7 years. The questionnaire contained 10 close-ended questions with two to eleven possible answers. Every participant chose one correct answer. Statistical significance was determined using a Chi-square test. Majority of participants had never received any kind of information on management of a knocked-out tooth. Questions in the nature of tooth injuries, a knocked-out tooth, tooth replantation and whether the knocked-out tooth should be placed back were answered confirmatively by 40.43%, 83.40%, 57.02% and 62.55% of participants, respectively. The questionnaire showed that 18.78% of participants were aware that replantation should be performed within 30 min. The appropriate cleaning and transport medium was chosen by 40.85% and 35.31% of participants, respectively. A nearby dentist would be visited by 66.38% of students. Only 8.08% of participants provided a correct answer to all of the knowledge-based questions. The &ldquo, I do not know&rdquo, answer was chosen by 18.30% of participants whenever it was offered. This indicates that the majority (89.78%) were not aware of the fact that the procedure they chose would be inappropriate. The current study confirmed that future primary school teachers have a lack of knowledge for immediate response to tooth avulsion, leaving small chances for a successful prognosis of tooth replantation.

Background: Following tooth extraction, the alveolar ridge undergoes dimensional changes. Various biomaterials are used to reduce alveolar ridge volume loss following tooth extraction by stimulating new bone formation. Maxresorb® inject (Botiss Biomaterials GmbH, Germany) is a biphasic material composed of a water‐based gel with 60% HA and 40% β‐TCP. BioOss® (Geistlich Pharma AG, Switzerland) is a porous bone mineral matrix which is produced by removing all organic components from bovine bone. Aim/Hypothesis: This study aimed to examine the regenerative potential of biphasic calcium phosphate (BCP) (Maxresorb® inject), by assessing histological results of bone biopsy collected from healing sockets and comparing them to inorganic bovine bone (BioOss®), after a healing period of 6 months. Materials and Methods: The study is designed as a randomized controlled, two ‐ phase study. In the first phase, 30 patients that qualified for participation in the research were divided randomly into 2 groups of 15 individuals. The bone substitute materials were implanted in extraction sockets after teeth removal. The first group underwent tooth extractions and socket augmentation with Maxresorb® inject. In the other group socket preservation was performed using BioOss®. In both groups, the sockets were covered by native collagen membrane. After 6 months of healing, biopsy was harvested prior to implant placement for histological analysis. Histological sections were examined under the light microscope. Results: Preliminary results ‐ The preliminary histological analysis revealed remaining BCP particles in intimate contact with the newly formed bone in the case of Maxresorb® inject. Histological specimens of BioOss® observed under light microscope also showed incorporation of the hydroxyapatite particles into the newly mineralized bone. In both materials, there were no histological signs of tissue inflammation. Furthermore, both materials exhibited easy handling and patients had no complications during healing period. Conclusions and Clinical Implications: Although a small number of patients were treated, along with the preliminary nature of this study, histological findings indicate osteoconductive properties of both materials included in this study. However, additional research is required to obtain histological and clinical features of Maxresorb® inject and BioOss® regarding their osteoconductive properties.

Background : Human bone has excellent regenerative potential. Bone remodeling is a continuous, balanced process, which includes activities of bone resorption and new bone formation. A wide variety of bone substitutes have been developed in order to avoid complications related to the use of autogenous bone, one of them being biphasic calcium phosphate (BCP). Maxresorb® inject (Botiss Biomaterials GmbH) is BCP in an injectable form composed of hydroxyapatite and beta- tricalcium phosphate in a ratio of 60 40. Aim/Hypothesis : The primary aim of this study was to histologically evaluate the potential for bone regeneration of Maxresorb® inject. The secondary aim was to clinically assess the handling of the Maxresorb® inject and the occurrence of complications during the healing period. Material and Methods : This study is designed as a prospective single- arm clinical trial and consists of two stages. In the first stage of the study, a total of 20 extraction sockets in 20 patients were augmented with Maxresorb® inject and covered by a resorbable membrane (Collprotect®, Botiss Biomaterials GmbH). Monitoring of the wound healing was done at day 1, 5 and 10 postoperatively. Following 6 months of healing, in the second stage, a re- entry procedure at the site of the pre- existing defect was performed in order to collect bone biopsies for histological analysis and for dental implant placement. Thus far, 5 biopsies were available for histological analysis. Biopsies were prepared according to routine methods, sectioned with a microtome and stained with hematoxylin and eosin. Finally, the specimens were examined under the light microscope. Results : Preliminary results- The preliminary histological findings of the biopsy specimen showed bony integration of the BCP granules into newly formed bone within the peripheral regions of the implant preparation sites. The granules were fully incorporated into bone tissue, and there were no histological signs of tissue inflammation. Procedure- wise, Maxresorb® inject showed easy handling and excellent filling of the extraction sockets. Wound healing was uneventful and without complications. Conclusion and Clinical Implications : In the present study, the regenerated bone was evaluated by descriptive histological examination. Maxresorb® inject showed osteoconductive potential for bone regeneration. In addition, due to its viscosity, Maxresorb® inject had excellent handling properties and filling of the bone defect, therefore simplifying the surgical procedure and positively influencing patients’ subjective experience. However, further research is needed to complete histological and clinical pieces of evidence of osteoconductive properties of Maxresorb® inject.

Svrha: Uzroci maksilofacijalnih ozljeda razlikuju se u zemljama diljem svijeta. U ovom istraživanju željeli su se istražiti pojavnost, vrste i uzroci maksilofacijalnih ozljeda s obzirom na dobne i spolne razlike pacijenata primljenih na Odjel za maksilofacijalnu kirurgiju KBC-a Osijek od siječnja 2011. do prosinca 2013. Ispitanici i postupci: Sudjelovala su ukupno 64 pacijenta – 41 muškarac (64,1 %) i 23 žene (35,9 %) u dobi od 18 do 86 godina (srednja dob 42). Prikupljeni podatci analizirani su s obzirom na spol, dob, uzrok i vrstu maksilofacijalne ozljede. Rezultati: Najčešći uzrok ozljeda u oba spola bio je pad (39 % muškaraca; 65 % žena). Sljedeći najčešći uzrok ozljeda kod muškaraca bila je tučnjava (29 %), a kod žena prometna nezgoda (26 %) (p < 0,05). Najčešća vrsta ozljede u oba spola bila je koštana (50 %; kod muškaraca zigomatična kost – 55 %, kod žena mandibula – 40 %) (p > 0,05). Najčešći uzrok ozljeda kod najmlađih pacijenata bila je tučnjava (43 %), a kod ostalih pad (50 – 70 %; p < 0,05). Najčešća vrsta ozljede u svim dobnim skupinama bila je koštana (više od 50 %; p > 0,05). Većina padova i ozljeda nastalih u tučnjavama uzrokovali su koštane ozljede, a ozljede mekih i dento-alveolarnih tkiva bile su prouzročene prometnim i sportskim ozljedama (p > 0,05). Zaključak: Podatci prikupljeni u ovom istraživanju pružaju vrlo važne informacije za provedbu buduće prevencije ozljeđivanja., Objectives: The occurrence and causes of maxillofacial trauma varies in different regions of the world. The aim of this study was to identify the occurrence, types and causes of maxillofacial injuries according to the age and gender differences in patients treated at the Department of Maxillofacial Surgery, University Hospital Center Osijek, between January 2011 and December 2013. Materials and methods: A total of 64 patients, 41 males (64.1%) and 23 females (35.9%), aged from 18 to 86 years (mean age 42) participated in the study. Data collected and analyzed included gender, age, cause of injury and the type of maxillofacial injuries. Results: The most common cause of injuries in both gender groups was falling down (39% males; 65% females). The second leading cause of injuries in males was interpersonal violence (29%) and in females traffic accident (26%) (p0.05). The most common causes of injuries in the youngest patients was violence (43%), and in others fall (50-70%; p0.05). The majority of the falls and violence caused bone tissue injuries, and soft tissue and dentalveolar injuries were detected in traffic and sports accidents (p>0.05). Conclusion: Falling down was the most common cause of oro-maxillofacial injuries in both men and women and in all three age groups. The leading type of injury was bone injury. The data obtained from this study provide important information for future prevention from injuries.

Background: Monitoring systems decouple monitoring functionality from application and infrastructure layers and provide a set of tools that can invoke operations on the application to be monitored. Objectives: Our monitoring system is a powerful yet agile solution that is able to online observe and manipulate SOA (Service-oriented Architecture) applications. The basic monitoring functionality is implemented via lightweight components inserted into SOA frameworks thereby keeping the monitoring impact minimal. Methods/Approach: Our solution is software that hides the complexity of SOA applications being monitored via an architecture where its designated components deal with specific SOA aspects such as distribution and communication. Results: We implement an application-level and end-to-end monitoring with the end user experience in focus. Our tools are connected to a single monitoring system which provides consistent operations, resolves concurrent requests, and abstracts away the underlying mechanisms that cater for the SOA paradigm. Conclusions: Due to its flexible architecture and design our monitoring tools are capable of monitoring SOA application in Cloud environments without significant modifications. In comparisons with related systems we proved that our agile approaches are the areas where our monitoring system excels

The aim of this study was to determine the extent to which the intensity of postoperative pain in the first seven days after lower wisdom tooth extraction is affected by operator experience, patient level of information and patient sex. Postoperative pain intensity after lower wisdom tooth extraction was assessed in 108 patients. Depending on the type of information given to each patient individually, the patients were divided into two groups: test group in which patients were provided with detailed standard written and verbal instructions and control group where patients only received detailed standard written instructions about treatment after surgery. Each of these two groups was divided into three subgroups depending on operator experience. Results of this study showed that the type of information irrespective of being given verbally or not had no effects on postoperative pain intensity, whereas operator experience and patient sex influenced postoperative pain intensity., Cilj ovoga istraživanja bio je utvrditi utjecaj radnog iskustva operatera, informiranosti pacijenta i spola pacijenta na intenzitet poslijeoperacijske boli prvih sedam dana nakon odstranjenja donjeg umnjaka. Provedeno je istraživanje vezano za intenzitet poslijeoperacijske boli nakon odstranjenja donjeg umnjaka kod 108 pacijenata. Ovisno o tipu informacije dane svakom pacijentu posebice pacijenti su podijeljeni u dvije skupine: ispitnu u kojoj su pacijenti dobili detaljan standardni pismeni i usmeni naputak te kontrolnu skupinu u kojoj su dobili samo detaljan standardni pismeni naputak o postupanju nakon operacijskog zahvata. Svaka od ovih dviju skupina ispitanika podijeljena je u tri podskupine ovisno o iskustvu operatera. Rezultati studije su pokazali da na intenzitet poslijeoperacijske boli nije imao utjecaj tip informiranosti pacijenta, dok su iskustvo operatera i spol pacijenta utjecali na intenzitet poslijeoperacijske boli.

Ameloblastoma, especially maxillary, is a rare benign neoplasm of odontogenic origin. Diagnosis of significant number of lesions is usually established postoperatively, because ameloblastoma, especially the unicystic form, mimics wide range of more frequent jaw lesions. From January 1993. to December 2005., three cases of the maxillary ameloblastoma were surgically treated at our Department. The authors present clinical, radiological and pathohistological features of the ameloblastomas in this rare localization with special attention to need of accurate preoperative diagnostics.
