Osteogenic cells transfer improving root coverage: A randomized clinical trial.

Background And Objective: The aim of this interventional, parallel-assignment, single-blinded, randomized, efficacy study was to investigate the efficacy of the treatment of gingival recessions by osteogenic cell transfer. This is the first randomized clinical trial of this nature.

Material And Methods: Treatment of Miller class I or II gingival recessions >4 mm was randomly defined by casual sorting and performed by newly forming bone graft (NFBG) and coronally advanced flap (CAF) or subepithelial connective tissue graft (SCTG) and CAF (control).

Oral health impact profile of head and neck cancer patients after or before oncologic treatment: an observational analytic case-control study.

Purpose: The objective of this study was to investigate the impact of oral health on the quality of life of patients with head and neck cancer (HNC) before and after oncologic treatment.

Methods: Forty cancer-free individuals (Cf group) and 40 HNC patients (Hnc group) were included in this study. Hnc group was also divided into two subgroups: Hnc 1 (pre-cancer therapy, n = 20) and Hnc 2 (post-cancer therapy, n = 20).

Bone demineralization with citric acid enhances adhesion and spreading of preosteoblasts.

Background: Previous studies have demonstrated that bone demineralization can improve consolidation in bone grafts. The biologic mechanisms underlying this phenomenon remain unclear.

Methods: Twelve adult male guinea pigs were used in this experiment.

Differential production of macrophage inflammatory protein-1alpha, stromal-derived factor-1, and IL-6 by human cultured periodontal ligament and gingival fibroblasts challenged with lipopolysaccharide from P. gingivalis.

Background: Fibroblasts are considered important cells in periodontitis. When challenged by different agents, they respond through the release of cytokines that participate in the inflammatory process. The aim of this study is to evaluate and compare the expression and production of macrophage inflammatory protein (MIP)-1alpha, stromal-derived factor (SDF)-1, and interleukin (IL)-6 by human cultured periodontal ligament and gingival fibroblasts challenged with lipopolysaccharide (LPS) from Porphyromonas gingivalis.

A modified approach for vestibuloplasty in severely resorbed mandible using an implant-retained postoperative stent: a case report.

Background: Severely resorbed mandibles often present a short band of keratinized tissue associated with a shallow vestibule. As a result, prominent muscle insertions are present, especially in the mental region of the mandible. This case report describes the deepening of the vestibular sulcus in an atrophic mandible by combining free gingival grafts harvested from the palate and a postoperative acrylic resin stent screwed on osseointegrated implants placed at the anterior region of the mandible.
