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.

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: 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.
