Background: The width of the attached gingiva is the distance between the mucogingival junction to the projection of the external surface of the bottom of the sulcus or the periodontal pocket. It varies from tooth to tooth and also among individuals of different age groups.
Aim: The aim of this study is to assess the full mouth mid-buccal width of attached gingiva and evaluate the difference in visual and histochemical method in identification of the mucogingival junction to calculate the width of the attached gingiva.
Material and Methods: A sample of 80 patients divided in four age groups were included and each group was assessed for mid-buccal width of attached gingiva either by Visual or Histochemical method utilizing stain for identification of mucogingival junction.
Results: It was seen that the width increases with age and there was no significant difference in the width by the two methods.
Conclusion: Width of attached gingiva varies in different areas of the mouth with maximum in incisors and minimum in premolars and also increases with age with no significant difference in the method of its assessment.
