Aims: To evaluate the mandibular bone cortical of patients with mucopolysaccharidosis on panoramic radiograph, through radiomorfometric indices. Study Design: Case-control study. Place and Duration of Study: Sample: Department of Diagnostic Imaging of the Universidade Estadual da Paraíba, Campus VIII, in the city of Araruna, PB, between January and December of 2015. Methodology: Panoramic radiographs of sixteen patients with mucopolysaccharidosis and 32 controls, organized by gender and age, composed the sample. The mandibular panoramic index, gonial index, antegonial index and mental index were evaluated. Pearson's Chi-square test, Fisher's exact test and Mann-Whitney test were used to statistical analysis with a level of significance of 5.0%. Results: Mucopolysaccharidosis patients were mostly female (62.5%), with a mean age of 12.31 + 7.16 years, MPS VI (50.0%) being the most prevalent. Patients with mucopolysaccharidosis had higher values in the gonial (1.86+0.48), the antegonical (4.36+1.24) and the mental (5.24+1.21). However, only the antegoniac index presented a significant difference (P=0.047). Conclusion: The antegoniac index was higher in patients with mucopolysaccharidosis and the other radiomorphometric measures were similar to those observed in the control group. Apparently, mucopolysaccharidosis is not related to decreased bone to mandibular quality.

Aims: This study aimed to report a case of multiple inflammatory fibrous hyperplasia in the upper lip, resulting from the association of lip sucking habit and the use of orthodontic appliance, treated with high-powered laser. Presentation of Case: A 42 years-old male patient, anxious, presented with five lesions in upper lip in close contact with dental appliance. Also, he had a habit of sucking his lip. After the removal of the appliance, it was performed a surgery using a diode laser (Thera Lase Surgery λ=808 nm, P=2.5 W). Discussion: The removal of the traumatic etiological agent is essential for the treatment of proliferative lesions, such as hyperplasias. After removal, if there is no complete regression of a small hyperplasia, surgical removal will be necessary. Diode surgical laser is a good alternative, due its advantages. Conclusion: It is very important to advise patients with harmful habits, as lip sucking, that with the persistence of the habit, new lesions will arise again. Monitoring psychological factors is also essential.

Ranulas are mucoceles located on the floor of the mouth. The main form of treatment for these lesions is surgical excision, but this can lead to complications such as hemorrhage, recurrence of the lesion, and damage to the lingual nerve. Thus, other therapeutic modalities are indicated, such as modified micromarsupialization, which is a simple technique and not associated with recurrences, and without the need of a new intervention in the postoperative period. An 11-year-old female child, nonwhite, presented with bubble-shaped lesion located on floor of the mouth, on the left side, with exophytic growth, sessile base, bluish coloration, measuring about 4.0 cm in diameter, showing well-defined limits, well-delimited contours and borders, smooth surface, and softened consistency. Under the diagnostic hypothesis of the ranula, a modified micromarsupialization was performed. After 90 days of observation, complete regression and repair of the lesion were observed, without recurrence. Modified micromarsupialization is a simple therapeutic modality, low cost, and well-tolerated by the patient, mainly the pediatric one, being considered very effective in the treatment of lesions of difficult clinical management, as the ranula.

The objective of this study was to identify the epidemiological profile of facial fractures and to associate with clinical-epidemiological variables. An epidemiological survey was conducted in which data retrieved from the records of patients with facial fractures were analyzed. Pearson χ(2) test, Student t-test, one-way analysis of variance, Bonferroni post-hoc test, and logistic regression were used for statistical analysis, adopting a level of significance of 5%. The sample consisted of 718 patients ranging in age from 21 to 30 years (56.4%), including 480 (66.9%) men. Traffic accidents were the main etiological agent (62.7%) and the nasal bones were the most affected (41.8%). An association was observed between age and etiology (P < 0.001), fractured bone (P < 0.001), type of treatment (P < 0.001), hospital length of stay (P < 0.001), and complications (P = 0.001). Patients with traffic accident [odds ratio (OR) = 3.08, P < 0.001] and fall (OR = 2.50, P = 0.049) as etiology had more risk of complications. The type of fractured bone was associated with etiology (P < 0.001), type of treatment (P < 0.001), hospital length of stay (P < 0.001), and complications (maxilla--OR = 1.90, P = 0.004). In conclusion, facial fractures predominantly affect men aged 21 to 30 years. Traffic accidents are the main etiology and the nasal bone is the site most affected. It was observed that the older the patient, the greater the susceptibility to falls, surgical treatment, hospital stay, and complications. Patients with maxillary or mandibular fractures remain hospitalized for longer periods of time. Fractures by traffic accident and fall had more risk of complications. The risk of complications was also higher in patients with maxilla fracture.

AIM The aim of the present study was to delineate the epidemiological profile of young patients with squamous cell carcinoma (SCC) treated at a healthcare service in northeastern Brazil. METHODS A cross-sectional study was performed involving the quantitative analysis of 51 medical records from patients diagnosed with SCC between 1998 and 2013. All patients aged ≤50 years were included in the study. Statistical analysis involved Pearson's χ2 -test, Fisher's exact test, and the Mann-Whitney U-test, with the level of significance set at 5% (P

Objectives To investigate the radiographic findings of mucopolysaccharidoses (MPS) on panoramic radiographs in a series of 16 patients. Study Design This retrospective cross-sectional study included panoramic radiographs of 16 patients with cytogenetically diagnosed MPS. Two blinded, previously calibrated observers evaluate the presence or absence of the following features: type of dentition; stage of dental age in comparison with chronologic age; delayed exfoliation of deciduous teeth; supernumerary teeth; teeth impaction; enlarged, cyst-like dental crypt; hypercementosis; taurodontism; generalized enamel hypoplasia; enlargement of the bone marrow spaces; thinning of cortical bone; unusual morphology of condyles; and flattening of the condylar head. Results The final sample was composed of 8 MPS IV, 7 MPS VI, and 1 MPS I cases. All patients presented unusual morphology of condyles. Cyst-like dental crypt (75%), taurodontism, and teeth impaction (68.75% each) were also overall common findings. Generalized enamel hypoplasia was exclusively identified in patients with MPS IV (75% of those patients). Conclusions Radiographic features of oral and maxillofacial manifestations in patients with MPS frequently encountered by dentists may help recognize the disorder. However, because of sample size limitations, it was not possible to infer any statistical relationship between the radiographic features and the types of MPS.

The aim of the present study was to compare the treatment plan outlined from the diagnosis obtained by two different cephalometric analyses with the clinical decision made for surgical treatment of patients with skeletal Class III malocclusion. For this purpose, 82 skeletal Class III patients were evaluated, divided into three groups according to the surgical procedure performed for dentofacial deformity correction. Their preoperative cephalometric radiographs were submitted to McNamara and Steiner cephalometric analyses. The association of variables was evaluated by Kappa correlation (α=5%). The agreement between indication of surgical procedures performed based on clinical decision and surgical treatment indicated based on the evaluation of McNamara and Steiner cephalometric analyses were not significant (p=0.609 and p=0.544, respectively). McNamara and Steiner analyses showed reasonable agreement with each other as to the diagnosis, but did not agree with the clinical decision to treat skeletal CIII patients. Both tests were equally inaccurate in the indication of the surgical treatment. O objetivo deste trabalho foi comparar o plano de tratamento delineado a partir do diagnóstico obtido através de duas análises cefalométricas distintas, com a decisão clínica tomada para o tratamento cirúrgico de pacientes portadores de maloclusão classe III esquelética. Para isto foram avaliados 82 pacientes classe III esquelética, divididos em três grupos de acordo com o procedimento cirúrgico realizado para a correção da deformidade dentofacial. Suas radiografias cefalométricas pré-operatórias foram submetidas à análise cefalométrica de McNamara e de Steiner. A associação das variáveis foi avaliada pelo teste de correlação de Kappa (α=5%). A concordância entre a indicação do tratamento cirúrgico baseado na decisão clínica e o tratamento cirúrgico proposto a partir da avaliação das análises de McNamara e de Steiner não foi significante (p=0,6094 e p=0,5442,respectivamente). As análises de McNamara e de Steiner apresentaram concordância razoável entre si para o diagnóstico, porém não apresentam concordância com a decisão clínica para o tratamento de pacientes CIII esquelética, sendo as duas análises igualmente imprecisas na indicação do tratamento cirúrgico dos pacientes da amostra.

Aims: The aim of the present study was to analyze the socioeconomic profile and academic performance of students of three courses on Campus VIII of the State University of Paraiba. Study Design: A quantitative, descriptive, cross-sectional study with an inductive approach was carried out involving students in the courses of dentistry, civil engineering and natural science on Campus VIII of the State University of Paraiba (northeastern Brazil) in 2013. Methodology: A total of 321 students were enrolled, and the sample was made up of 238 participants who answered a semi-structured questionnaire addressing socioeconomic

Objective The aim of this study was to perform a survey of diagnosed lesions at a Stomatology Clinic at a University for 1 year. Study Design Retrospective study with analysis of 58 patients’ records. Poorly completed records or uncertain diagnoses were excluded. Results Through the analysis of the records, a male prevalence (51.7%) aged above 41 years (58.6%) was observed, with lower levels of education (elementary school) and lower salary. The majority of the diagnosed lesions were single, localized in the lip, especially the lower lip. Actinic cheilitis was the most prevalent diagnosis, followed by vascular injuries, and lower prevalence of leukoplakia and carcinoma. Biopsy was the complementary exam most performed, followed by imaging examinations. Laser therapy was the most used treatment not only to surgery, but also for biomodulation. Conclusions Actinic cheilitis had a great prevalence in the patients. Male patients older than 41 years and considered at risk for oral cancer were the most seen by the Health Service. Ease of access for people, particularly those with low salaries, to a referral service of Oral Diagnosis located in the interior, can help to overcome the deficiencies or shortcomings of the Public Service.

Objective The aim of this study was to verify the prevalence of oral cancer in patients admitted to a referral oncology hospital. Study Design Cross-sectional and descriptive study, in which 166 patients diagnosed with cancer were examined. Results Of the admitted patients, there was a prevalence of males (64.5%) with an average age of 51.7 years and nonwhite color (59%). Among the various types of cancer, acute leukemia (34.9%) was the most prevalent, followed by lymphomas (16.9%), pharynx and larynx (7.8%), mouth (6%), lung (6%), and head and neck cancer (6%). Chemotherapy was the most prescribed (58.4%) therapeutic approach, followed by its association with radiotherapy (18.7%), and only radiotherapy (9.6%). Radiotherapy was the most used treatment for oral cancer. Conclusions In the evaluated sample, oral cancer was the fourth most prevalent type, predominating for the sixth decade of life, in a ratio of 4 males to 1 female. Radiotherapy was the most-used treatment. Financial support: PIBIC.

Objective The aim of this study was to determine the prevalence of oral acute complications related to antineoplastic treatment. Study Design The sample consisted of 166 patients in a reference hospital in which clinical examination was carried out. Results There was male prevalence (64.5%) aged between 31 and 60 years (51.2%) and nonwhite skin color (59%). Acute leukemia (34.9%) and lymphomas (16.9%) were the most frequent neoplasms found. Chemotherapy was the widely prescribed antineoplastic treatment (87.3%), usually associated to other therapeutic approach (33.1%). The most prevalent complaint was burning mouth (25%), followed by toothache (21.4%), dysphagia (16.6%), xerostomia (15.5%), and oral ulceration (14.3%). Oral mucositis was the most prevalent toxicity (18.7%), followed by xerostomia (15.7%) and candidosis (8.4%). Conclusions The dentist must be aware of the oral acute complications in patients under chemotherapy antineoplastic treatment because they have high morbidity, mainly mucositis stage I, present in this study in all ages and sexes.

A 70-year-old female patient was referred to the stomatology clinic for evaluation of an injury on her tongue. On medical history, it was found she was a patient with type 2 diabetes mellitus and hypertension, using antihypertensive, hypoglycemic, and antihistamine agents along with insulin, eye drops, and sedatives. She was also being seen by an endocrinologist. She is allergic to many medications (acetylsalicylic acid and its derivatives, dipyrone, and nonsteroidal anti-inflammatory drugs). On oral examination, the patient had a dry oral mucosa with little lubrication and mild candidosis of the tongue, treated by ketoconazole. The clinical diagnosis was Sjogren syndrome. Anti-SSA and anti-SSB were found to be positive. A rheumatoid factor (RF) test was within the normal limits, as was the hemogram. The patient has not yet consented to lip biopsy due to decompensated diabetes (glycated hemoglobin 7.6% and fasting glycemia 115 mg/dL). The patient was referred to the doctor for diabetes control and is under proper follow-up care.

An 11-year-old female patient complained of "a blister in the mouth." Intraoral examination evidenced a bullous lesion in the left mouth floor measuring approximately 4 cm with exophytic growing, bluish coloration, defined limits, soft consistency, smooth surface, and 5 days of evolution. Clinical diagnosis was ranula. Micromarsupialization was performed after infiltrative anesthesia, and surgical knots were made far from the mucosa by the interposition of a hemostatic clamp, forming fistulas originating from the epithelization around the thread, allowing salivary flow. In the transoperative period, there was immediate drainage of part of the content retained within the lesion, reducing its initial volume. Surgical knots were removed after 7 days, and the patient was followed up for 3 months. The lesion regressed entirely without signals of recurrence, ruling out the need of excision. Therefore, micromarsupialization stands as a conservative therapy for the treatment of ranulas and mucoceles of significant size.

A 41-year-old male patient, a white farmer, was referred to the stomatology clinic diagnosed as having actinic cheilitis. Clinically, atrophic and leukoplastic areas were observed throughout the lower lip, and loss of the border between the red lip skin and the cutaneous portion. An incisional biopsy was performed in the leukoplastic area, and histopathologic examination showed atrophic and atypical stratified orthokeratinized pavement epithelium with severe oral epithelial dysplasia. The therapeutic approach was the removal of all leukoplastic areas using the high-intensity diode laser for re-epithelialization of the affected mucosa. Proper follow-up is being performed every 3 months, and after 9 months, no signs of relapse were observed. Because of the potential for malignancy of actinic cheilitis and the presence of dysplastic epithelial alterations, an early approach is justified. The vaporization of the labial tissues with high-intensity diode laser was effective in superficial removal of affected tissues.

Objective: To present a literature review of the evidence of involvement of the Hepatitis C Virus (HCV) in the etiology of oral lichen planus (OLP), addressing some aspects of this controversial topic. Material and methods: We performed a literature search through the Virtual Health Library (VHL), identifying articles published in journals indexed in the following databases: BBO, LILACS and MEDLINE. In combination were used as descriptors: hepatitis C, lichen planus and leukoplakia, considering the time span of 10 years (between 1998 and 2008) and languages: Portuguese, English and Spanish. Thus, 30 publications were included. Results: It was found that the association between HCV infection and the LPB was investigated, but most results were inconsistent. Conclusion: The results, additional studies are recommended to prove the current hypotheses about the association and the pathogenesis of lichen planus with HCV infection.

O objetivo desta pesquisa foi estudar a prevalência da leishmaniose tegumentar americana com repercussão na cavidade bucal, no município de Alagoa Grande (Paraíba), no período compreendido entre 1996 e 2004. Foi utilizada, para a pesquisa, a verificação das fichas clínicas da Leishmaniose Tegumentar, na Secretaria da Saúde da referida cidade, onde se observou a existência ou não de repercussão nasobucofaríngea. 53 pacientes apresentaram Leishmaniose Tegumentar Americana, 64% eram do sexo masculino, na faixa etária entre 20 e 24 anos e mais de 65 anos; 45,16% eram analfabetos, 96,2% apresentaram lesões cutâneas, 3,8% lesões na mucosa, 3,8% apresentaram repercussões bucais, 100% realizaram a Intradermorreação de Montenegro para confirmar o diagnóstico clínico, e 61,29% faziam uso de antimonial penta valente. O índice de prevalência mucoso foi de 0,67 casos para cada 10.000 habitantes. Concluiu-se que estudos de prevalência demonstram a real situação da epidemiologia no país, havendo a necessidade de os cirurgiões-dentistas observarem as características regionais de cada afecção como forma de melhor diagnosticá-las. A Leishmaniose Tegumentar no município de Alagoa Grande, Paraíba, demonstra bem essa necessidade, devido às suas características epidemiológicas.
