OBJECTIVE: The aim of the present study was to evaluate the effect of periodontal dressing on post-operative pain and swelling after surgical crown lengthening.
MATERIALS AND METHODS: A blind, randomized, clinical trial was carried out with 36 patients. Following surgical crown lengthening, the individuals were randomly allocated to the periodontal dressing group (PDG) and control group (CG, non-placement of periodontal dressing). Pain and discomfort were analyzed using a visual analog scale (VAS), verbal scale (VS) and the number of analgesics consumed in 7 days post-operatively. Post-operative infection, stability of the gingival margin and type of healing were also evaluated.
RESULTS: The PDG had a significantly higher percentage of responses of 'strong pain' on the VS in the first day post-operatively (33.3% vs 5.3%, p = 0.03) and greater pain on the first and second days post-operatively based on the VAS. Moreover, a significant difference between groups was found regarding gingival swelling after 7 days. However, gingival recession was found in 57.8% of the sites in the CG and only 5.5% of sites in the PDG. No change in condition was found among individuals with conjunctive tissue/bone exposure in the CG in the immediate post-operative period and 80% of the patients in the PDG had healing by first intention after 7 days.
CONCLUSION: The use of periodontal dressing seems to be preferable following surgical crown lengthening with connective tissue/bone exposure. However, adequate post-operative analgesic strategies should be employed due to the possibility of intense pain in the first 24 hours.
