title: Comparative study of micro deformations resulting from axial and non-axial static loads under three prosthetic implant elements

description: INTRODUCTION: The control of the micro strain surrounding implants is a factor that can lead to a better osseointegration and maintenance of bone structures.OBJECTIVE: evaluate in vitro, using strain gauge analysis , the influence of the axial and non-axial static load in implant-supported fixed partial dentures, varying the point of load application.MATERIAL AND METHOD: In a block of polyurethane three internal hexagonal implants were installed, on implants abutments microunit were connected with torque of 20 Ncm, and plastic prosthetic cylinders were screwed on to the abutments, which received standard patterns cast in Co-Cr alloy (n=10). Four strain gauges were bonded on the surface of the block tangentially to the three implants. Each metallic structure was screwed onto the microunit with a 10 Ncm torque. With a load application device (DAC) static vertical loads of 30kgf were applied for ten seconds at five predetermined points (A, B, C, D and E).RESULT: Result analyzed by RM ANOVA, in which the effect of the point of load application and differents specimens were not statistically significant, whereas regarding the points of load application presented statistical differenced (p=0.0001). Applying Tukey's multiple comparison tests.CONCLUSION: The application of load on the non-axial points D and E produced an increase in the magnitude of micro strain around implants.

title: Enamel microhardness of primary teeth of cerebral palsy children

description: INTRODUCTION: Cerebral palsy subjects present reduced salivary flow, which may predispose to enamel hypomineralization and dental caries. AIM: To compare the enamel microhardness of anterior and posterior primary teeth of normorreactive children (NR) and children with cerebral palsy (CP). MATERIAL AND METHOD: The sample was consisted of 58 exfoliated/extracted primary teeth distributed into 4 groups: (A) anterior teeth of CP (n= 14), (B) anterior teeth of NR (n=16),(C) posterior teeth of CP (n=14) and (D) posterior teeth of NR (n=14). The teeth were hemisectioned, embedded in acrylic resin, grounded and polished. The longitudinal microhardness analysis was carried out in a microdurometer with a Knoop indenter with a 25-gram load for 5 seconds. Three rows of 12 indentations were made from the outer surface from 10 to 180 mm. The rows were spaced 100 mm from each other. The values of the three measurements at each distance were averaged for each tooth and, afterwards, for each group. The non-parametric statistical test used was the Mann-Whitney U (α=5%). RESULT: The microhardness means data were 253.5 ± 55.3 (A), 247.6 ± 45.7 (B), 284.4 ± 68.7 (C) and 252.2 ± 53.8 (D).There was no significant difference between the groups A and B, as well as groups C and D for each distance and global average (p&gt;0.05). CONCLUSION: It can be concluded that the enamel microhardness of anterior and posterior primary teeth of cerebral palsy children was similar to the normorreactive children.

title: Quality of life in patients undergoing third molar extraction

description: INTRODUCTION: The removal of third molars can cause disorders and damage in quality of life. OBJECTIVE: This study aimed to evaluate the quality of life in patients underwent surgery, discussing the most commonly events observed. MATERIAL AND METHOD: Sixty patients of a private surgery clinic from João Pessoa/PB were underwent extraction of third molars by the same surgeon and and under the same conditions. Data were collected in two steps: the first one was accomplished at the day of the procedure, which were noted down both patient and surgery informations. The second step were realized seven days after the procedure, the patients answered a form about life quality at the postoperative period. RESULT: 71,4% patients underwent to osteotomy and odontosection maintained their normal activities and 28,6% did not. While in patients not submitted to the techniques, 40,9% maintained their normal activities and 59,1% did not. According to Pell & Gregory classification, 71,4% of patients Class 3 maintained normally their social activities, while 60% of patients Position C didn´t. Patients who remained socially isolated and were underwent to techniques, 71,4% reported as the main reason the pain, and 100% of patients Class 3 and 80% of patients Position C have chosen the same answer. CONCLUSION: The results suggest that the techniques used in the transoperative does not influence the quality of life during the postoperative and the position has more influence than the class, in respect to the development of normal social activities.

title: Identification of Candida species in patients with denture stomatitis and evaluation of susceptibility to miconazole and photodynamic therapy

description: INTRODUCTION: Denture stomatitis (DS) is a common oral mucosal lesion in complete denture users. It is usually seen as limited to the area beneath an upper denture, characterized by focal or diffuse erythema of the denture-supporting tissues. The etiology of this lesion is multifactorial, although Candida infection is a common cause of disease. OBJECTIVE: To relate the DS with the presence of Candida, to identify the most prevalent species of Candida using CHROMagar Candida(r) medium and to verify the susceptibility of the isolates to miconazole and photodynamic therapy (PDT). MATERIAL AND METHOD: The sample was constituted of 45 complete denture users, 30 patients with clinical DS and 15 without disease. Palatal mucosa and dentures were frictioned with sterilized swabs and sown in CHROMagar Candida(r) medium to identify species of C. albicans, C. tropicalis and C. krusei. After incubation and observation of the plaques, the yeasts were reisolated in Sabouraud Agar medium for verification of species susceptibility to miconazole and PDT. RESULT: Candida species were found in 53,33% of the patients with DS and in 6,67% of the patients without DS, considering all of the palatal mucosa (p=0,008) and denture (p=0,001). The most prevalent species were C. albicans (36,67% and 53,33%), followed by C. tropicalis (13,33% and 16,67%) and C. krusei (13,33 and 6,67%), on mucosal and denture, respectively. The samples were more sensitive to miconazole than PDT (p&lt;0,0001). CONCLUSION: There was an association between the presence of Candida and DS, and C. albicans the most prevalent species. Miconazole provided better results in the elimination of in vitro colonies of Candida compared with PDT.

title: Knowledge on oral cancer among dentistry students at Federal University of Maranhão

description: INTRODUCTION: Oral cancer is a multifactorial disease of high incidence worldwide and considered a public health problem, in which prevention and early diagnosis are the best ways to reverse this situation. PURPOSE: To evaluate the level of knowledge on oral cancer in a population of dentistry students. METHOD: A questionnaire on oral cancer was applied to 150 students from six classes, divided into three groups according to their semesters. The variables studied were statistically analyzed by applying the chi-square test with confidence interval of 95% and significance level of 5%. RESULT: Eighty-eight students (60.61%) considered their level of knowledge on oral cancer good and regular, while 37.93% rated their knowledge as insufficient. Squamous cell carcinoma was listed as the most common cancer by only 38.25% of students, with the highest percentage of correct answers being observed for groups 2 (55.56%) and 3 (67.39%). The level of knowledge on the risk factors increased over the semesters; however, 77.85% considered their level of confidence to perform diagnostic procedures low. CONCLUSION: The level of knowledge on oral cancer was considered good or regular among dentistry students, and although they showed good level of knowledge on the risk factors and to specific issues of the disease, there is a clear need to implement continued educational measures throughout the course to consolidate learning on this disease.

title: Incidence of the soft tissue changes around unerupted or impacted third molars

description: INTRODUCTION: Dental follicles remain adjacent to the crown of an unerupted or impacted tooth. Changes in dental follicles can occur and form a solitary cyst around the crown of the tooth, deemed dentigerous cysts. OBJECTIVE: The aim of this study was to determine the incidence of soft tissue changes around unerupted or impacted third molars. MATERIAL AND METHOD: Pericoronal tissue of patients who were referred to our clinic for removal of third molars for a variety of reasons was examined histopathologically. Follicular spaces were measured from periapical and panoramic radiographs by each author independently. RESULT: Of the 37 specimens submitted for histopathologic examination, 19 normal follicular tissues (51%), 11 arrangements typical of a cyst (30%) and 7 normal tissues of oral mucous (11%) were found. CONCLUSION: Cystic changes may be encountered in the histopathologic examination of radiographically normal unerupted or impacted third molar follicles.

title: Edentulism, denture wearing and self-perceived of oral health among elderly

description: Aim The aim of this study was to verify whether self-perceived of oral health among elderly shows consistency with their oral condition, verified from the examination of oral inspection, considering tooth loss, usage and necessity of dentures. Material and method 103 volunteers who attend the Reference Center for Seniors Foundation Pro-Family Blumenau-SC participated. Data were collected through oral examination and questionnaire that composes the Geriatric Oral Health Assessment Index (GOHAI). Result Most of participants was women (83.5%) with 70 years old in average. Edentulism is high with 91.3% users of dental prostheses and 53.3% needing some type of prosthesis. The average value of the GOHAI index in the general group was 29.22, classified as "bad" self-perceived of oral health. Among men and those with natural teeth oral condition was considered "regular" with values 31.3 and 31.7, respectively. Conclusion The self-perceived of oral health can be considered consistent with poor oral condition found, marked by high prevalence of missing teeth. The prosthetic rehabilitation did not contribute to the improvement of self-perceived oral health. These data should guide the planning of oral health services to promote health and self-care.
