A total of 62 patients diagnosed with Stage III-IV periodontitis underwent non-surgical periodontal therapy. At 24 hours post-treatment, patients were recalled to the clinic for reassessment using air-stimulated Visual Analog Scale (VAS) and Schiff Cold Air Sensitivity Scale measurements. Two teeth per patient were randomly selected based on a VAS score greater than 4 and a Schiff score of 2 or 3. A total of 52 patients who met the inclusion criteria were included in the study. This study was designed as a randomized, parallel clinical trial. The 52 patients were randomly allocated into three treatment groups: Group 1 received the desensitizing agent Gluma, Group 2 underwent Er,Cr:YSGG laser treatment, and Group 3 received a combination of Gluma and Er,Cr:YSGG laser therapy. Desensitizing agent applications were performed according to the designated treatment protocols.To assess changes in dentin hypersensitivity over time, patients were recalled for follow-up evaluations at 1 week, 2 weeks, 1 month, 2 months and 6 months post-application. The 6-month follow-up of the study was completed with 48 patients (16 patients for each study group). At each follow-up visit, air-stimulated VAS and Schiff scale measurements were employed to quantify hypersensitivity levels.

Inclusion Criteria:
* 1\. No reported or clinically detected dentin hypersensitivity prior to the initiation of non-surgical periodontal therapy.
2\. Presence of at least five teeth with probing pocket depths (PPD) ≥6 mm. 3. Systemically healthy individuals with no history of systemic diseases that may interfere with periodontal outcomes.
4\. Absence of deep restorations or visible cracks in the teeth adjacent to those selected for hypersensitivity evaluation.
5\. No previous treatment for dentin hypersensitivity and no current use of desensitizing toothpaste or products.
6\. Clinical diagnosis of Stage III or IV periodontitis, involving periodontal support loss in more than 30% of teeth.
7\. A clinical attachment level (CAL) ≥5 mm and radiographic evidence of bone loss extending to the mid-root level.
8\. Age 18 years or older at the time of enrollment
Exclusion Criteria:
