    ABSTRACT: 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.

    ABSTRACT: This study aimed to evaluate the length of the holes drilled for the placement of zygomatic implants using two surgical techniques: the original Brånemark and the Exteriorized (extrasinus) protocols. The most frequent implant length used and position where the implants emerged in the zygomatic bone were recorded. Both surgical techniques for inserting zygomatic implants were performed on the right and left sides of 18 dry adult skulls. The depth of the drilling holes in the zygomatic bone for placement of zygomatic implants and the corresponding implant length were measured. The position where the implant emerged was recorded using a standardized division of the zygomatic bone surface into 13 sections (Fig. 3). The Exteriorized technique showed significantly longer drilling holes for zygomatic implants than the Brånemark technique (P<0.001). For both techniques, the most commonly used implant lengths were 30 and 35 mm, and the most frequent position where the implants emerged were sections 9 and 12. The results suggest that the Exteriorized technique increases the length of the drilling holes in the zygomatic bone, which may provide higher initial mechanical stability for zygomatic implants than the original Brånemark technique.

    ABSTRACT: 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.

    ABSTRACT: Resumo 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. Palavras-chave: displasia cleidocraniana; disostose cleidrocraniana; Síndrome de Scheusthauser-Marie-Sainton; anormalidades dento-faciais.
