Systemic risk indicators for peri-implant diseases in individuals with implant-supported fixed prostheses: A cross-sectional study.

Purpose: The present study aimed to identify the systemic risk indicators associated with peri-implant mucositis and peri-implantitis in individuals with implant-supported fixed prostheses.

Materials And Methods: In this cross-sectional study, clinical evaluations of periodontal and peri-implant conditions were performed by a single examiner in a sample of 71 volunteers with 360 implants. Peri-implant mucositis was defined as the occurrence of bleeding on probing in association with redness and swelling or suppuration, without bone loss.

Assessment of fractal dimension and panoramic radiomorphometric indices in women with celiac disease.

Objectives: To assess the panoramic radiomorphometric indices and fractal dimension in women with celiac disease.

Methods: The sample consisted of 20 women with celiac disease and 20 healthy women (control group). The mandibular cortical index classification, panoramic mandibular index, mental index, and fractal dimension were evaluated on panoramic radiographs.

Bioactive Glass Particles in Two-Dimensional and Three-Dimensional Osteogenic Cell Cultures.

This study aimed to investigate the influence of a three-dimensional cell culture model and bioactive glass (BG) particles on the expression of osteoblastic phenotypes in rat calvaria osteogenic cells culture. Cells were seeded on two-dimensional (2D) and three-dimensional (3D) collagen with BG particles for up to 14 days. Cell viability and alkaline phosphatase (ALP) activity was performed.

Root Coverage in Smokers with Acellular Dermal Matrix Graft and Enamel Matrix Derivative: A 12-Month Randomized Clinical Trial.

This study investigated whether enamel matrix derivative (EMD) contributes to root coverage of gingival recessions performed with acellular dermal matrix graft (ADMG) in smokers during a 12-month follow-up. A sample of 19 smokers presenting bilateral Miller Class I or II gingival recessions were included. Selected sites randomly received both ADMG and EMD (test) or ADMG alone (control).

Expression of osteoblastic phenotype in periodontal ligament fibroblasts cultured in three-dimensional collagen gel.

Objective: To investigate the influence of a three-dimensional cell culture model on the expression of osteoblastic phenotype in human periodontal ligament fibroblast (hPDLF) cultures.

Material And Methods: hPDLF were seeded on bi-dimensional (2D) and three-dimensional (3D) collagen type I (experimental groups) and and on a plastic coverslip (control) for up to 14 days. Cell viability and alkaline phosphatase (ALP) activity were performed.

Acellular dermal matrix graft with or without enamel matrix derivative for root coverage in smokers: a randomized clinical study.

Aim: The aim of this randomized controlled clinical study was to compare the use of an acellular dermal matrix graft (ADMG) with or without the enamel matrix derivative (EMD) in smokers to evaluate which procedure would provide better root coverage.

Material And Methods: Nineteen smokers with bilateral Miller Class I or II gingival recessions ≥3 mm were selected. The test group was treated with an association of ADMG and EMD, and the control group with ADMG alone.

Influence of light-curing units and restorative materials on the micro hardness of resin cements.

Aim: The aim of this study was to evaluate the effect of indirect restorative materials (IRMs) and light-curing units (LCUs) on the micro hardness of dual-cured resin cement.

Materials And Methods: A total of 36 cylindrical samples (2 mm thick) were prepared with dual-cured resin cement (Relyx ARC) photo-activated with either a QTH (Optilight Plus) for 40s or a LED (Radii) light-curing unit for 65s. Photo-activation was performed through the 2-mm- thick IRMs and the samples were divided into six groups (n=6) according to the combination of veneering materials (without, ceramic and indirect resin) and LCUs (QTH and LED).
