Many mouth rinses(MR) and toothpaste (TP) are released with the statement of whiten your teeth, but without specifying the percentage of hydrogen peroxide and pH. The aim of this study was to evaluate the concentration of hydrogen peroxide and pH of some MR and TP available on the market. 3 were evaluated trademarks of MR and TP divided into 6 groups (n = 5): EB: G1- Colgate Plax Whitening (CPW); G2 Listerine Whitening (LW); G3-Cepacol Whitening Plus (C) and TP: G4-Aquafresh Ultimate White (MF); G5-Close up White now (CU); G6-Smile Xtreme and White (SO) and group G7-Opalescence PF control 10% (OP). For the evaluation of hydrogen peroxide dosing was used titration method with potassium permanganate and the PH evaluation was through pHmeter. Data were submitted to analysis of variance. The average amount of hydrogen peroxide and pH detected, according to the methodology used, it may be concluded that both have low amounts of hydrogen peroxide in regarding the control group, acid pH to mouth rinses and basic pH for toothpastes. Clinical relevance: hardly the mouth rinses and toothpastes evaluated will provide teeth whitening due to low amount of presented hydrogen peroxide and limited contact time with teeth. The mouth rinse is not indicated for long-term use due to the acid PH. [ABSTRACT FROM AUTHOR]

Piezosurgery has its own characteristics such as precise cuts, selective and millimetric and also a clean surgical area that is considerate a less invasive surgery and revolutionary in oral surgery. The pneumatization of the maxillary sinus tend to difficult the rehabilitation of the posterior part of the maxilla on edentulous patients, making it hard to correct the condition without bone graft. Surgeries of sinus lift, therefore has its risk of punctuating the Schneider membrane, using rotatory instruments can damage the membrane but due to the selectivity for mineralized tissues performed with the piezoelectric technique suits very well for the patient and also the dentist safety.

Excessive gingival display during smile can result in compromised esthetics. This study aims to report a case of excessive gingival display with multiple etiologies treated by means of modified lip repositioning technique associated with esthetic crown lengthening. A 23-year-old female patient, with 5-mm gingival display during smile caused by altered passive eruption and hypermobility of the upper lip, underwent the modified lip repositioning technique associated with gingivectomy followed by flap elevation and ostectomy/osteoplasty. Seven months after the second procedure, the patient had her esthetic complaint solved appearing stable in the observation period. The modified lip repositioning technique is an effective procedure employed to reduce gingival display and when associated with esthetic clinical crown lengthening, can appropriately treat cases of gummy smile.

This study is the result of an observational study of temporomandibular dysfunction and facial pain (TMD and OFP) in the city of Maringa, State of Parana in 2011 2014. The information was obtained through interviews structured for questionnaire Axis I and II of the RDC /TMD, conducted with 500 people between 20 and 65 years, users of the Public Health System. This research aimed to observe asymptomatic patients for TMD, who had signs of dysfunction, associated factors as the etiology, prevalence and facial pain. In the sample of 500 people, all subjects responded that they did not have pain in the face, in maxillary, her temple (head), in front of the ear or in the ear last month, of which, 59.2% (n = 296) of people were female. Although all patients didn't presented pain, 57.0% (n = 285) had sleep disorder, and 23.8% (n = 119) with disc displacement reduction in the right or left, 28.0% (n = 140) disk displacement with reduction in pain, 24.8% (n = 124) left lateral deviation / right (uncorrected). The result of this study on the correlation of the absence of symptoms in the presence of TMD and OFP signs, demonstrates the need for clinical examination for diagnosing TMD, since 100% had no pain symptoms, but had TMD.

Background: The aim of this study was to evaluate, by means of pull-out test, the bond strength of fiberglass posts when cemented with different lengths in endodontically treated teeth. Materials and Methods: Sixty single-rooted bovine roots were cut in the cementoenamel junction with 21 mm length. They were endodontically treated and randomly divided into three groups (n = 20). Group 1 - Preparation of ⅞of the remaining roots; Group 2 - Preparation of ½ of the remaining roots and Group 3 - Preparation of ¼ of remaining roots. For all groups it were used posts n = 3 (Exacto, Angelus, Brazil), and cemented with self-etching resin cement (RelyXU200). After cementing posts, the samples were thermocycled (10.000 cycles/5°C and 55°C). The pull-out test was performed on a universal testing machine (EMIC - DL500) and the values obtained were statistically analyzed by analysis of variance (one-factor ANOVA) and multiple comparison test of Tukey, with level of significance of 5%. Results: The mean values ± standard deviation in Newtons (N) were: Group 1 = 120.5 (±42.8) A, Group 2 = 103.1 (±31.2) AB, Group 3 = 41.2 (±22.4) C, P < 0.005. Conclusion: The preparation of ½ of remaining root appears to be a viable alternative when ⅞of the preparation of the remaining root is not possible, but more results are needed for clinical validation.

In this manuscript, we present a rare case report of giant complex odontoma in the maxillary sinus, where the applied therapy included complete excision of the lesion with a conservative approach. Odontomas are also called benign growth abnormalities or hamartomas. They represent a more common type of odontogenic tumor and are related to various disorders such as bad dental placements, expansion, increased volumetric bone, and no eruption of permanent teeth. Usually they have an asymptomatic evolutionary course. The etiologic factors, although obscure, are related to local trauma, infection, and genetic factor. The structural composition of an odontoma consists of mature dental tissues. Odontomas can be differentiated according to their anatomical presentations: Compound odontoma-clusters of several denticles and complex odontoma-well defined tumefaction mass. The diagnosis can be performed by radiographic examination. [ABSTRACT FROM AUTHOR]
