Context: Biologic width (BW) is an important entity to consider when planning restorative or prosthetic procedures. Though many studies are available in the literature that offer varying dimensions for this entity in healthy dentition, there is a paucity of studies that have measured biologic width in cases of periodontitis.
Aims: This study was designed with the aim of measuring BW dimensions in both health and disease.
Settings and Design: 41 systemically healthy patients with an age range of 18 – 42 years were included in this analytical study.
Material and Methods: BW dimensions were measured by subtracting sulcus depth from the distance between gingival margin and osseous crest by trans sulcular probing. Measurements were again made in 20 patients with advanced periodontitis after completion of phase one therapy.
Statistical analysis: Mean and standard deviation for the groups were calculated and one way analysis of variance (ANOVA) was used to compare BW dimensions among groups.
Results: Mean BW dimensions in a healthy periodontium were recorded as 1.83±0.23 mm. At sites with advanced periodontitis, this was 1.52±0.36 mm which was statistically significantly different from the former (p<0>one therapy, mean BW was 1.85±0.25 mm.
Conclusions: BW dimensions differ significantly in disease as compared to health but after phase one therapy the dimensions tend to be restored.

Keywords: Biologic width, Periodontal disease, Gingiva.
Key Messages: This article focuses on analyzing changes in biologic width dimensions in periodontal health and disease and also changes in dimensions observed after phase one therapy. A knowledge of these changes will prove valuable while planning periodontal treatment
