Testosterone Increases Fibroblast Proliferation in vitro Through Androgen and Estrogen Receptor Activation
Background: Skin-related disorders and periodontitis are distinct diseases that have been associated with altered levels of testosterone. Understanding the mechanisms through which testosterone mediates gingival enlargement in animals and humans is crucial for preventing or treating this condition. In this study, we investigated the impact of different doses of androgens, the role of aromatase inhibition, and the effects of testosterone association with sex hormone receptor antagonists or aromatase inhibitors on human gingival fibroblast proliferation and migration in vitro. Methods:...

Objectives: Human beta-defensins (hBDs) play an important role in the susceptibility to periodontitis. This study aimed to evaluate the levels of hBD-2 and hBD-3 in gingival crevicular fluid (GCF) of individuals with and without periodontitis. Methods: Twenty periodontally healthy individuals (H) and 20 with periodontitis (P) were recruited. GCF samples were collected from healthy sites (Hh; n=20) from H individuals; and from healthy sites (Ph; n=20), sites with gingival inflammation but no...
Objectives: The objective of this study was to assess the quality of randomised clinical trials (RCT) published in the field of periodontology in compliance with CONSORT guidelines and also to identify any associated influencing factors. Methods: Quality of reporting in accordance with the 2010 CONSORT checklist was assessed and scored for RCTs published between 2015-2018 in three major periodontal journals: Journal of Periodontology (JP), Journal of Periodontal Research (JPR) and Journal of...
Aims: This study aimed to determine the dimensional change in the alveolar ridge after using an anodized titanium foil (Tseal) in association with bovine bone (BB) grafting in damaged extraction sockets by cone-beam computerized-tomography. Materials and Methods: Fifteen patients who had one hopeless tooth with over 80% of the buccal wall lost were selected and then the teeth were carefully extracted. The alveolar socket was filled with bovine bone and the Tseal was trimmed and adapted over...
Background: This systematic review evaluated the most effective therapeutic approach to treat periodontal furcation defects with a minimum follow-up of 12 months. The primary outcome was clinical attachment level (CAL). Secondary outcomes were probing pocket depth, gingival margin level, gingival index and plaque index. Methods: A comprehensive search of studies published up to December 2019 and listed in PubMed/MEDLINE, Scopus, and Cochrane Library databases was performed in accordance with...
Aims: This case series study aimed to assess the clinical outcomes of a novel protocol for the treatment of patients with severe periodontitis. Materials and Methods: Twenty (20) patients with severe periodontitis underwent a single session of One-Stage Full-Mouth Instrumentation (OSFMI) involving supra- and sub-gingival air-polishing with erythritol and chlorhexidine powder and ultrasonic root surface debridement and calculus removal, in association with systemic amoxicillin and...
Aim: The aim of this study was to determine the effects of probiotics on peri-implant diseases. Materials and Methods: PubMed-MEDLINE, Scopus, Literature in the Health Sciences in Latin America and the Caribbean (LILACS) and Science Direct were searched until September 2019. Three authors independently carried out this search, using the following search algorithm to explore databases using Boolean operators (“peri-implant diseases” OR “dental implants”) AND (“probiotics” OR...
