The random allocation sequence will be created using the Random Allocation Software with a block size of two. Permuted block randomization is a method in which each block is selected with a size equal to the number of study groups. In this study, there are two possible blocks: AB and BA. One of the blocks will be randomly selected; if the first block (AB) is chosen, the first participant will be assigned to group A and the second participant to group B. This process will continue until all participants have been allocated. The advantage of this method is that it ensures equal sample sizes in both study groups, Blinding description: Patients will be randomly assigned to two groups: the test group (with Coe-Pak dressing) and the control group (without Coe-Pak dressing). The surgical information of each patient will be placed in a sealed opaque envelope and handed to the surgeon by the surgical ward nurse. After the surgery is completed, the opaque envelope will be opened and the patient’s group allocation will be revealed. 3 Evaluation the effect of non-eugenol periodontal dressing (Coe-Pak) on pain and wound healing after crown lengthening surgery. Intervention group: In the intervention group, after performing crown lengthening surgery and suturing, we apply periodontal Coe-Pak dressing according to the manufacturer’s instructions and in an adequate amount over the surgical site for a duration of one week..

Our primary outcome variable is pain assessment using the Visual Analog Scale (VAS). We will compare pain levels between individuals who receive a periodontal pack (Co-Pac) after crown-lengthening surgery and those who do no. Timepoint: Pain will be measured during the first 7 days following the crown-lengthening procedure. Method of measurement: pain will be measured using the Vas scales (0-10). Presence of infection after surgery. Timepoint: One week after the operation. Method of measurement: Infection is evaluated based on the presence of swelling, redness, and pain.
