Deepening of the inferior labial vestibule was undertaken according to the technique of Edlan and Mejchar on 25 patients aged 17–55 years (X =). Observations were made at intervals, the total period ranging from (X =). Mean vestibular depth before operation was 2.24 ± 0.15 and post‐operatively 6.96 ± 0.23, the difference of 4.72 mm. was statistically significant (P < 0.01). Pre‐operatively the gingival state on the labial aspect of the mandibular central incisors showed a mean value of 2.28 ± 0.36 units and 0.90 ± 0.20 units post‐operatively. The difference was statistically significant (P < 0.01). The Plaque Index pre‐operatively was 1.70 ± 0.31 and 0.88 ± 0.20 post‐operatively (difference ‐ significant: P < 0.05). The correlation coefficient between the plaque and gingivitis scores before operation, r =+0.36, and post‐operately, r =+ 0.43 suggests that there was a definite relation which was strengthened as a result of the operation. It is concluded that when there is only a limited amount or no gingival tissue on the labial aspect of the mandibular anterior teeth, but no pockets the technique provides a predictable way in which gingival health can be achieved and maintained.
