Results The results show that in test group, the width of wound after extraction had shrunk significantly greater than control group, both in buccolingual and mesiodistal directions.

The quality of healing process as assessed by standardized index of Landry, Turnbull and Howley (1988) showed good, very good and excellent healing in test group as follows, 5 subjects, 8 subjects and 3 subjects,respectively,
whereas in control group: 5 subjects, 10 subjects, and 1 subjects, respectively.

Adverse events None
Outcome measures it is confirmed that chlorhexidine gel has the beneficial effect in enhancing wound healing after non-surgery tooth extraction and may be suggested as adjuvant treatment and home care. It merits further studies to evaluate the effect of chlorhexidine with the evaluation of clinical and radiographic examination after tooth extraction.
