Coronally positioned flap with or without acellular dermal matrix graft in the treatment of class II gingival recession defects: A randomized controlled clinical study.

The aim of the randomized controlled single blind study is to evaluate the treatment of Miller's class II gingival recessions by coronally positioned flap (CPF) with or without acellular dermal matrix allograft (ADMA). Ten patients with 20 sites with maxillary bilateral Miller's class II facial recession defects were selected randomly into two groups of test (ADMA+CPF) and control (CPF alone) group with each group having 10 recession defects to be treated. The clinical parameters included plaque index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL), recession height (RH), recession width (RW), height of the keratinized tissue (HKT), and thickness of the keratinized tissue (TKT).

Obesity and periodontal disease.

Obesity is characterized by the abnormal or excessive deposition of fat in the adipose tissue. Its consequences go far beyond adverse metabolic effects on health, causing an increase in oxidative stress, which leads not only to endothelial dysfunction but also to negative effects in relation to periodontitis, because of the increase in proinflammatory cytokines. Thus obesity appears to participate in the multifactorial phenomenon of causality of periodontitis through the increased production of reactive oxygen species.
