The article describes the case of a 15-year-old female model presented with a small incisal fracture on the discolored maxillary left central incisor caused by a traumatic injury. It also discusses the process of reproducing opalescent and counter-opalescent effects with direct resin composites in teeth transplantation. The teeth were cleaned with pumice and shade selection was performed. The silicone matrix was positioned and the resin composite was internally adapted to the tooth structure and was initially light cured for 20 seconds.

Objective: To portray and assess the interfacial morphology achieved with self-etching systems in dentin under observation by scanning electron microscopy. Method and Materials: Ten caries-free extracted erupted human third molars were used in this study. The occlusal enamel was removed, and 10 dentin disks with a thickness of 800 ± 200 μm were obtained by slow-speed sectioning with a diamond saw parallel to the occlusal surface. A standard smear layer was created on the occlusal surface by wet sanding with 600-grit sandpaper for 60 seconds. The dentin disks were randomly assigned to one of the systems: AdheSE (Ivoclar Vivadent), Optibond Solo Plus-Self-Etch (Kerr), Tyrian SPE (Bisco) as self-etching primers, and Adper Prompt Self-Etch (3M Espe) and One-Up Bond F (Tokuyama) as self-etching adhesives. All systems were applied according to the manufacturers' instructions. After application of the adhesive systems, a 1.0-mm-thick layer of a flowable composite resin (Filtek Flow; 3M Espe) was applied to the treated dentin surface and light cured for 40 seconds. The specimens were then processed for observation by scanning electron microscopy. Results: All self-etching systems achieved the formation of sealed interfaces and hybridized areas with variable extents except for the self-etching adhesive One-Up Bond F, which showed some gap formation and poor hybridization. Optibond Solo Plus-Self-Etch presented a more consistent adhesive interface with thicker hybrid layers, numerous resin tags, and lateral branches. Conclusion: Regarding the micromorphology aspect, Optibond Solo Plus-Self-Etch showed the finest result, while One-Up Bond F was not able to produce a satisfactory ultrastructural morphology.

The article discusses the fluorescence of natural teeth and composite restorations. In the field of dentistry, it has been assumed that fluorescence is the absorption of energy in the nonvisible spectrum. Natural teeth show a strong blue fluorescence when exposed to black light. Meanwhile, the fluorescence of composite resin restoration is independent of their perceived color when seen under white light. This observation is clinically important because truly esthetic restorations should match the color of natural teeth in daylight as well as under different light sources.

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.

In dentistry, the gingival fissure around the teeth or tissue damage produced by surgical and/or accidental procedures can be a gateway to oral microbiota, directly into the bloodstream, which can result in the colonization of the endocardium, causing infective endocarditis. Infective endocarditis is caused by the infection of the endocardial surface, characterized as a rare disease, but which, if triggered, can cause inflammation and destruction of the endocardium, heart valves or vascular endothelium. Since the discussion about the use or non-use of antibiotic prophylaxisis is not pacified in the Dental literature, this review aims to explain about the necessity of antibiotic prophylaxis prescription to the patients considered at risk, with potential risk and low risk of infection associated with dental surgery.

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.

This study's aim was to evaluate the degradation rate of hydrogen peroxide (H2O2) and to quantify its penetration in tooth structure, considering the residence time of bleaching products on the dental enamel. For this study, bovine teeth were randomly divided according to the bleaching product received: Opalescence Xtra Boost 38%, White Gold Office 35%, Whiteness HP Blue 35%, Whiteness HP Maxx 35%, and Lase Peroxide Sensy 35%. To analyze the degradation of H2O2, the titration of bleaching agents with potassium permanganate was used, while the penetration of H2O2 was measured via spectrophotometric analysis of the acetate buffer solution, collected from the artificial pulp chamber. The analyses were performed immediately as well as 15 minutes, 30 minutes, and 45 minutes after product application. The data of degradation rate of H2O2 were submitted to analysis of variance (ANOVA) and Tukey tests, while ANOVA and Fisher tests were used for the quantification of H2O2, at the 5% level. The results showed that all products significantly reduced the concentration of H2O2 activates at the end of 45 minutes. It was also verified that the penetration of H2O2 was enhanced by increasing the residence time of the product on the tooth surface. It was concluded that the bleaching gels retained substantial concentrations of H2O2 after 45 minutes of application, and penetration of H2O2 in the dental structure is time-dependent.

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]

The aim of this paper is to show that a variety of psychosocial, physical factors, among others - such as stress, depression, sleep, obesity, bariatric surgery etc. - can bring us problems such temporomandibular disorder and orofacial pain. Exactly 15 patients were evaluated with slightly less; thereabout a half of patients were easonable health. The other party evaluates their health as good. About a half of the patients evaluated did not have interference from facial pain and only 6.7% rated their facial pain with intensity 8. 40% of individuals in the group 13.3% reported that their facial pain intensity was 10. The data collected to date does not yet allow observing differences significant levels of pain and the presence of chronic pain related to TMD according to the presence of obesity or performed with bariatric surgery.

The aim of this work was to establish a ratings showdown. Made by 3 distinct groups of volunteers at 10 patients aged between 20 and 30 years, 10 dentists general practitioners and 10 dentists specialists in aesthetics. Thus sought to highlight the importance of a work together patient-professional. 100 pictures of different types of smiles of patients seen in the master course in operative dentistry at the Ingá College and prosthesis were selected and organized into slides listed of 1 to 100. This sequence of slides was evaluated individually subjective manner by the volunteers in the Group of patients where 61% considered harmonics 39% no harmonics (being the cause: 35% teeth, 16% gums 28% lips, 17% two earlier and 4% all earlier), 66% female 34% male. The Group of general practitioners 56% harmonics 44% no harmonics were considered (being the cause: 19% teeth, 8% gums, 11% lips, 55%, previous two and 7% all earlier), 79% female 21% male. The Group of experts 42% of smiles were considered harmonics, 58% no harmonics (being the cause: 25% teehh 12% gums, 18% lips, 40%, previous two 5% all earlier), 88% female 12% male. With this we see the specialist with a higher capacity of critical evaluation. [ABSTRACT FROM AUTHOR]

Introduction: The association between periodontal disease (PD) and chronic kidney disease (CKD) is bidirectional, as individuals with CKD may have oral manifestations, and PD may develop as a complicating factor of CKD. The systemic inflammatory response found in periodontal patients may have a synergistic effect on the chronic inflammation found in CKD. Objective: To review the literature to find evidence of the importance of the association between these two conditions. Methods: A PubMed search of studies published between 2003 and 2013 was conducted to retrieve clinical trials and systematic reviews. Results: Six clinical trials and one systematic review met the established criteria. Clinical trials used different approaches for the association between PD and CKD. Studies investigating the association between PD and CKD used a crossover design, evaluation of the oral manifestations in patients with CKD, and analysis of the effect of periodontal treatment on markers of renal disease. Conclusion: In addition to systemic functions, CKD also affects oral health, particularly causing periodontal tissues. Moreover, PD may affect kidney functions and lead to complications in individuals with CKD. [ABSTRACT FROM AUTHOR]
