Clinical biological width dimension around dentition of a selected Saudi population.
Pak Oral Dental J Jan ;25(1):81-6.

Biologic Width (BW) is the physiologic dimension of the junctional epithelium and connective tissue attachment located between the base of the sulcus and the alveolar bone crest. The purpose of the study is to find the average biological width around teeth of selected Saudi patients and to correlate these dimensions with the periodontal status. The data was gathered by measurements from 50 Saudi male patients with age ranging from 20-50 years old. The Ramfjord teeth (six teeth) were selected for each patient and clinical parameters such as plaque index, bleeding index, tooth status, probing depth were evaluated. The distance from gingival margin to crest o f bone at three buccal sites per tooth; which were the mesiobuccal, buccal and distobuccal areas were measured. Clinical biological width was calculated by subtracting Probing depth from the distance between gingival margin to crest of bone. The results showed that the average biological width for this study was 1.24 mm with a highest value at the mesiobuccal area (1.4 mm). The mean Plaque index was 0.64, the mean bleeding index was 0.47 and the mean probing depth was 2.44 mm. It can be concluded that the term clinical biological width is more reliable to be used clinically, and creation of 1.24 mm at maximum from proposed margin of restoration when restoring fractured or carious teeth during surgical crown lengthening is recommended to maintain the dimension of clinical `biological width.
