Classification of periodontal biotypes with the use of CBCT. A cross-sectional study.

Objectives: The aim of this study is to investigate the relationship between periodontal morphometric parameters and to develop a biotype classification based on the variables examined with the use of cone-beam computed tomography (CBCT).

Materials And Methods: Forty-two periodontally healthy subjects that underwent a CBCT examination as part of a different diagnostic procedure participated in the study. Measurements were performed on sectional images and included gingival thickness and labial bone plate thickness midbuccally, crown width to crown length ratio, bone crest to the CEJ distance and bone crest to the gingival margin distance midbuccally, and at the approximal aspects of 186 maxillary anterior teeth.

Crestal bone resorption after the application of two periodontal surgical techniques: a randomized, controlled clinical trial.

Aim: To radiographically assess, by means of digital subtraction radiography, crestal bone loss following two periodontal surgical techniques, over a period of 6 months.

Material And Methods: A total of 30 chronic periodontitis patients participated in this randomized controlled clinical trial and were separated into two groups. Modified Widman flap was applied in the control group and apically positioned flap, without intervention to the bone, in the experimental group.

The influence of sex steroid hormones on gingiva of women.

Steroid sex hormones have a significant effect on different organ systems. As far as gingiva are concerned, they can influence the cellular proliferation, differentiation and growth of keratinocytes and fibroblasts. Estrogen is mainly responsible for alterations in blood vessels and progesterone stimulates the production of inflammatory mediators.
