Displasia cleidocraniana: aspectos clínicos e radiográficos e relato de um caso clínico

Cleidocranial dysplasia is characterized by multiple abnormalities, mainly those related to craniofacial and corporal skeleton, besides oral and dental anomaly. The aim of this paper is to report a case of a female patient, 25 years old, who has characteristical signs of this pathology. General aspects of the disease, as well clinical and radiographic findings are also discussed and empathized, due to its rare occurrence.A Displasia Cleidocraniana (DCC) é caracterizada por múltiplas anormalidades, principalmente aquelas pertencentes ao esqueleto craniofacial e corporal, e também anormalidades buco-dentais. O objetivo deste artigo é apresentar o caso de uma paciente, gênero feminino, 25 anos, portadora de sinais característicos dessa entidade patológica. Os aspectos gerais da doença, assim como os sinais clínicos e radiográficos da síndrome são também discutidos e enfatizados, dada a sua rara ocorrência

Supragingival treatment as an aid to reduce subgingival needs : a 450-day investigation

This study investigated the clinical effects of using a supragingival biofilm control regimen (SUPRA) as a step prior to scaling and root planing (SRP). A split-mouth clinical trial was performed in which 25 subjects with periodontitis (47.2 ± 6.5 years) underwent treatment (days 0–60) and monitoring (days 90–450) phases. At Day 0 (baseline) treatments were randomly assigned per quadrant: SUPRA, SRP and S30SRP (SUPRA 30 days before SRP). The full-mouth visible plaque index (VPI), gingival bleeding index (GBI), periodontal probing depth (PPD), bleeding on probing (BOP), and clinical attachment loss (CAL) were examined on days 0, 30, 60, 90, 120, 270, and 450. Baseline data were similar among all groups. From days 0 to 60, the groups showed similar significant decreases in VPI and GBI. Reductions in PPD for the SRP (3.39 ± 0.17 to 2.42 ± 0.16 mm) and S30SRP (3.31 ± 0.11 to 2.40 ± 0.07 mm) groups were greater (p < 0.05) than those for the SUPRA group. This pattern was also observed for BOP. Attachment gain was similar and greater for the SRP (3.34 ± 0.28 to 2.58 ± 0.26 mm) and S30SRP (3.25 ± 0.21 to 2.54 ± 0.19 mm) groups compared to the SUPRA group. Results were maintained from day 90 forward. Overall, the S30SRP treatment reduced the subgingival treatment needs in 48.16%. Performance of a SUPRA step before SRP decreased subgingival treatment needs and maintained the periodontal stability over time

Perda de peso de materiais usados para o selamento mecânico de dentes não vitais submetidos a agentes clareadores.

To evaluate the loss of weight of two glass ionomers (GIC) Vidrion R® (VR) and Vitremer® (VT) which were submitted to bleaching agents: 37% Carbamide Peroxide (CP) and 35% Hydrogen Peroxide mixed with Sodium Perborate (PP) using Zinc Phosphate (ZP) cement as control. The influence of the storage time since the sample preparation until the whitening application (used right after the restoration or 24 hours later).Seventy (70) samples were divided into 10 groups: in the odd the materials were utilized immediately after the sample preparation; in the even, 24 hours later with the following distribution. The weight chance of these specimens were measured before the immersion in bleaching agents and 21 days after using the analytical balance. Mean value and SD was calculated and data was analyzed using ANOVA/Kruskal-Wallis test at a 0,01 significance level. VT proved to be less soluble than VD R and not show any estatistically significance difference in comparison with ZP.O presente trabalho avaliou a solubilidade do cimento de ionômero de vidro quimicamente ativado Vidrion R® -SS White- (VR) e do reforçado com partículas resinosas Vitremer® -3M- (VT) submetidos ao tratamento com diferentes substâncias clareadoras, empregando o fosfato de zinco como controle. Os agentes clareadores utilizados foram o peróxido de carbamida (PC) e uma pasta composta por perborato de sódio + peróxido de hidrogênio (PP), ambos a 37%. Também foi avaliada a influência do tempo decorrido desde o preparo do corpo-de-prova até o momento de aplicação do clareador (se o mesmo for utilizado imediatamente após a restauração ou 24 horas depois). Foram confeccionados, com matriz padronizada, 70 corpos de prova divididos em 10 grupos (n=7) sendo que nos grupos ímpares os materiais foram utilizados imediatamente após o preparo dos corpos-de-prova e nos pares, 24 horas depois. Previamente à imersão nos clareadores, os corpos de prova foram lavados em água “Mili Q”, enxaguados e secos a uma temperatura média de 50oC durante 30 minutos até a obtenção do peso constante. Após, foram pesados em Balança Analítica de Precisão GEHAR A6-200 e imersos nos agentes clareadores sendo novamente lavados, secos e pesados no período de 21 dias, tempo final do experimento. Os resultados foram analisados através do teste de Kruskal- allis (ñ < 1%). De acordo com a metodologia empregada, foi possível verificar que o Vitremer demonstrou ser menos solúvel aos agentes clareadores quando comparado ao Vidrion R. Quando comparado com o Fosfato de zinco nenhuma diferença estatisticamente significante foi encontrada
