The authors present the case of a 17-year-old White male patient complaining of enlargement in the gingival region and the fundus of the left maxillary anterior vestibular sulcus. The clinicopathological diagnosis was plexiform unicystic ameloblastoma. With this report, the authors illustrate the importance and complexity of a differential diagnosis of lesions with a cystic aspect in the anterior region of the maxilla, among them inflammatory radicular cysts, odontogenic keratocysts, adenomatoid odontogenic and unicystic ameloblastoma.

The effectiveness of microwave disinfection of maxillary complete dentures on the treatment of Candida-related denture stomatitis was evaluated. Patients (n = 60) were randomly assigned to one of four treatment groups of 15 subjects each; Control group: patients performed the routine denture care; Mw group: patients had their upper denture microwaved (650 W per 6 min) three times per week for 30 days; group MwMz: patients received the treatment of Mw group in conjunction with topical application of miconazole three times per day for 30 days; group Mz: patients received the antifungal therapy of group MwMz. Cytological smears and mycological cultures were taken from the dentures and the palates of all patients before treatment at day 15 and 30 of treatment and at follow-up (days 60 and 90). The effectiveness of the treatments was evaluated by Kruskal-Wallis and Mann-Whitney tests. Microbial and clinical analysis of the control group demonstrated no significant decrease in the candidal infection over the clinical trial. Smears and cultures of palates and dentures of the groups Mw and MwMz exhibited absence of Candida at day 15 and 30 of treatment. on day 60 and 90, few mycelial forms were observed on 11 denture smears (36.6%) from groups Mw and MwMz, but not on the palatal smears. Miconazole (group Mz) neither caused significant reduction of palatal inflammation nor eradicated Candida from the dentures and palates. Microwaving dentures was effective for the treatment of denture stomatitis. The recurrence of Candida on microwaved dentures at follow-up was dramatically reduced.

Aims: To investigate the prevalence of oral mucosa alterations in patients with type 2 diabetes and to identify possible risk factors related to oral mucosa alterations.Methods: 146 patients with type 2 diabetes and 111 age-and gender-matched healthy controls subjects were consecutively recruited from Araraquara School of Dentistry to answer a structured questionnaire designed to collect demographic data as well as current and former history of diabetes. Clinical examination of the oral mucosa was carried out by a stomatologist.Results: A higher prevalence of oral mucosa alterations was found in patients with diabetes than in patients without diabetes (p < 0.001), with significant difference to development conditions (p < 0.0001), potentially malignant disorders (p < 0.0001) and fungal infections (p < 0.05). In the multiple logistic regression, diabetes (odds ratio 9.9 IC 5.11-19.16) and smoking habit (odds ratio 3.17 IC 1.42-7.12) increased the odds of oral mucosa alterations significantly.Conclusions: Patients with diabetes mellitus not only showed an increased prevalence of oral mucosa alterations but also a significant percentage of potentially malignant disorders. These findings elucidate the necessity of regular clinical examination to ensure early diagnosis and prompt management of oral mucosa lesions in patients with diabetes. (C) 2011 Elsevier B.V.

Cysts are considered as nonneoplastic benign lesions that, when present for a long period of time, can cause some discomfort, especially related to the treatment form. Among the types of cysts of the maxilla, the dentigerous cyst (DC) presents substances between the dental follicle and the crown of the tooth with high potential for resorption, and the odontogenic keratocyst tumor (OKT) characterizes for its noticed rapid growth pattern and the possibility to develop carcinomas in the lesion wall. The DC is the most common type among the developing odontogenic cystic lesions, while the OKT represents 10% of these lesions. The prevalence of the OKT found in the current study was superior to the DC, opposing data of the evaluated literature, as well as the predominance in relation to the age group. Dentigerous cyst cases were found mostly in younger individuals, whereas the OKT was observed mainly in individuals between the third and fourth decades of life. This fact reflects the fragility of these features while establishing the presumptive diagnosis and insinuates the strong relation with a probable genetic predisposition. In relation to sex and race, the findings in this article were similar to those found in the literature, highlighting the possibility of a hormonal involvement. However, the anatomopathologic examination remains essential to define the main diagnosis of the lesions observed by means of imaging examinations, providing for safer diagnoses to plan the treatment.

OBJETIVO: Devido à importância da cicatrização dos defeitos que venham a acometer os tecidos ósseos, este estudo tem o objetivo de avaliar a ação do polímero de mamona durante a neoformação óssea. MÉTODOS: Para isto, um grupo de 45 ratos foi utilizado. Realizou-se a criação de um defeito ósseo na região do arco zigomático de todos os animais, sendo que todos estes defeitos foram preenchidos com o polímero de mamona. Decorridos períodos de 15, 30, 60, 90 e 120 dias, os animais foram sacrificados e seguiram-se as tramitações laboratoriais de rotina para análise histológica. RESULTADOS: Os resultados mostraram que o polímero de mamona auxiliou no processo cicatricial. CONCLUSÃO: Concluiu-se que o polímero de mamona auxiliou no processo regenerativo do defeito ósseo criado experimentalmente, atuando como um agente osteocondutor.

To evaluate the efficacy of ProTaper Universal rotary retreatment system and the influence of sealer type on the presence of filling debris in the reinstrumented canals viewed in an operative clinical microscope. Forty-five palatal root canals of first molars were filled with gutta-percha and one of the following sealers: G1, EndoFill; G2, AH Plus; G3, Sealapex. The canals were then reinstrumented with ProTaper Universal rotary system. Roots were longitudinally sectioned and examined under an operative clinical microscope (10x), and the amount of filling debris on canal walls was analyzed using the AutoCAD 2004 software. A single operator used a specific software tool to outline the canal area and the filling debris area in each third (cervical, middle, and apical), as well as the total canal area. Data were analyzed by Kruskal-Wallis test and Tukey test at P < 0.05. Sealapex demonstrated significant differences in the average of filling debris area/canal among the 3 thirds. This group revealed that apical third showed more debris than the both cervical and middle third (P < 0.0001). Endofill presented significantly more filling debris than Sealapex in the cervical third (P < 0.05). In the middle (P = 0.12) and apical third (P = 0.10), there were no differences amongst groups. Debris was left in all canal thirds, regardless of the retreatment technique. The greatest differences between techniques and sealers were found in the cervical third. Microsc. Res.
