Postoperative pain and wound healing are compared after using conventional scalpel technique in comparison with the intervention which is using Soft tissue Trimmer for cases of gingival hyperplasia.

In the control group:

1. Following the local anaesthetic administration, A reverse bevel gingivectomy will be performed with a #15c scalpel.
2. The borderline of gingiva will be determined via the use of a pointer dental tweezers, and excessive gingival tissue will then be removed with Gracey curettes
3. No periodontal packs to be applied to ensure accurate evaluations of follow-up pain and wound healing

In the intervention group:

1. Following the local anaesthetics administration for the Soft tissue trimmer(STT) gingivectomies, Soft tissue trimmer will be used with 400-rpm rotary systems and with no serum irrigation, per the manufacturer's recommendation.
2. Gingivoplasties will be performed with the same Soft tissue trimmer to easily provide a knife-edge appearance.
3. No periodontal packs will be applied to ensure accurate evaluations of follow-up pain and wound healing.
