Treatment of multiple recessions with collagen matrix versus connective tissue: a randomized clinical trial.

The objective of this study was to determine whether collagen matrix (CM) is an alternative to connective tissue graft technique (CTG) in the treatment of multiple gingival recessions (GR). The indication of CM for the treatment of multiple GR is not yet clear. More studies are needed to better understand this treatment modality, as an alternative to CTG.

Severe loss of clinical attachment level: an independent association with low hip bone mineral density in postmenopausal females.

Background: Bone loss is a feature of both periodontitis and osteoporosis, and several studies have analyzed whether the periodontal destruction could have been influenced by systemic bone loss. The aim of this study is to assess the association between clinical attachment level (CAL) and bone mineral density (BMD) at the lumbar spine and hip, lifestyle, smoking, sociodemographic factors, and dental clinical variables in postmenopausal women.

Methods: One hundred forty-eight women were interviewed using a structured written questionnaire and clinically examined.
