Evaluation of the efficacy of a commercially available regimen vs brushing alone on established plaque and gingivitis on adolescents: Study protocol for a randomized, controlled, blind clinical trial.

BACKGROUND: Dental biofilm accumulation and poor personal oral hygiene are known major risk factors for gingivitis and halitosis. However, it is not clear how studies compare the effectiveness of hygiene regimens, associated with outcomes centered on patients. METHODS: A randomized, blind, controlled clinical trial involving 58 participants aged from 12 to 17 years, who search the Department of Pediatric Dentistry of Universidade Metropolitana de Santos, will be conducted. Immediately, the volunteers will be inserted into Group 1 (commercially available hygiene regimen) or Group 2 (tooth brushing alone). In Group 1, participants will receive Colgate Total 12 toothpastes, Plax mouthwashes and Colgate Ultrasoft toothbrushes, while Group 2 will use Colgate Cavity Protection toothpastes and Colgate Ultrasoft toothbrushes. The interventions will be conducted in the periods of 1, 3, and 6 months after the baseline, when the evaluations will also be performed. Biofilm and halitosis indexes will be evaluated. Data regarding discomfort, satisfaction and the socioeconomic/individual characteristics will also be computed. DISCUSSION: Although toothbrushing has shown positive effects in decreasing biofilm and in gingival health, there is no comparison in the literature of different brushing regimens with halitosis measurement in adolescents. In addition, the effectiveness of these protocols would be confirmed from the acceptability of the volunteers.

Randomized clinical trial of four adhesion strategies in cervical lesions: 12-month results.

The aim of this study was to evaluate the 6- and 12-month clinical performance of four adhesion strategies from the same manufacturer (Kerr) in non-carious cervical lesions (NCCLs) using two evaluation criteria. Thirty-five patients, with at least four NCCLs each, participated in this study. After samplesize calculation, 180 restorations were assigned to one of the following groups: OFL (Optibond FL), OSP (Optibond Solo Plus), XTR (Optibond XTR), and AIO (Optibond All-In-One). The composite resin Filtek Supreme Ultra (3M ESPE) was placed incrementally. The restorations were evaluated at baseline, after 6 months, and after 12 months, using both the FDI and the USPHS-modified criteria. Statistical analyses were performed with Friedman repeated measures, ANOVA by rank, and the McNemar test for significance in each pair (α=0.05). Six restorations (2 for OFL, 1 for OSP, 2 for XTR, and 1 for AIO) were lost at 12 months (P>0.05 for both evaluation criteria). Marginal staining was observed in seven restorations using the FDI criteria (P>0.05) and three restorations using the USPHSmodified criteria (P>0.05). Eight restorations (2 for OSP, 3 for XTR, and 3 for AIO) were classified as Bravo for marginal adaptation using the USPHSmodified criteria (P>0.05). However, 62 restorations (14 for OFL, 12 for OSP, 15 for XTR, and 21 for AIO) were classified as Bravo using the FDI criteria (P>0.05). The four adhesion strategies showed similar clinical retention at 6 and 12 months. The FDI evaluation criteria tend to be more sensitive than the USPHS-modified criteria.

Simplificando la adhesión con un sistema adhesivo universal: reporte de casos / Clinical application of a new universal adhesive system: case reports

Los sistemas adhesivos tienden a ser cada vez más simplificados y versátiles. Hasta el presente, el clínico todavía debe elegir entre adhesivos autoacondicionantes o convencionales. Objetivo: mostrar la aplicación clínica de un nuevo sistema adhesivo considerado universal, debido a que puede ser usado como adhesivo autoacondicionante o como uno convencional. Caso clínico: fueron realizadas restauraciones cervicales en lesiones no cariosas con varias posibilidades de utilización de un nuevo adhesivo (Scotchbond(TM) Universal, 3M Espe), aplicando el ácido fosfórico en toda la cavidad y dejando la dentina seca o húmeda, o aplicando el ácido fosfórico solamente en el esmalte, o aplicando sólo el adhesivo sin grabado previo con ácido fosfórico. Después de restaurar con resina compuesta, todos los casos fueron evaluados clínicamente en el inicio del tratamiento y a los 6 meses. Conclusión: los resultados demostraron un excelente desempeño clínico de este nuevo sistema adhesivo, utilizado con cualquiera de las distintas técnicas clínicas propuestas. No obstante, deben realizarse estudios de larga duración en un mayor número de casos clínicos, a fin de comprobar los resultados aquí presentados

Análise espectrofotométrica e visual do clareamento dental: relato de caso clínico / Spectrophotometric and visual analysis of dental bleaching: clinical case report

O trabalho apresenta descrição de um caso clínico de clareamento dental onde as alterações de cor foram avaliadas através de dois métodos: visual (utilizando escala Vita Clássica) e instrumental (utilizando espectrofotômetro Easyshade). Foi realizado clareamento dental de consultório com peróxido de hidrogênio a 35% Mix One Supreme (Villievie). A cor foi mensurada antes e após a realização do tratamento clareador com os dois métodos. O paciente relatou satisfação com a alteração de cor e esse resultado pôde ser comprovado tanto pela escala de cor quanto pelo espectrofotômetro. A técnica clareadora utilizada mostrou-se eficiente, porém, para resolver completamente o problema estético do paciente foi realizado também fechamento de diastema com resinas compostas fotopolimerizáveis.

Tooth color is considered a complexity phenomenon, influenced by coefficients such as environment illumination conditions, translucence, opacity, light spread, brightness, and structures and morphophysiological processes of sight. The aim of this study was to describe a clinical case of dental bleaching, in which the modifications of color were evaluated by two methods: visual (using Vita Classic scale) and instrumental (using Easyshade spectrophometer). A clinical dental bleaching was performed with hydrogen peroxide at 35% Mix One Supreme (Villievie). The color was measured before and after the bleaching with both methods. The patient reported satisfaction with the color alteration, and that result can be testified both by color scale and spectrophometer. The bleaching technique was very effective, however, in order to solve the esthetic problem completely, diastema was also closed with compound photopolymerizable resin.
