NCT07874789

Brief Summary

This randomized, single-blind, controlled clinical trial aims to evaluate the effects of a topical curcumin spray on post-extraction wound healing and postoperative symptoms in adults undergoing first molar extraction. Participants will be randomly assigned to one of three groups: curcumin topical spray, 0.12% chlorhexidine topical spray, or standard postoperative care without a topical spray. The interventions will be applied twice daily for 7 days. Postoperative pain will be assessed using a visual analog scale, while wound healing will be evaluated using the Landry, Turnbull, and Howley Healing Index. Wound dimensions will also be recorded during follow-up. In addition, salivary levels of inflammatory biomarkers, including interleukin-1β (IL-1β), tumor necrosis factor-alpha (TNF-α), and prostaglandin E2 (PGE2), will be analyzed to assess the local inflammatory response during the postoperative healing period.The study aims to compare the clinical effects of topical curcumin with chlorhexidine and standard postoperative care during the early healing period after tooth extraction.

Outcome Measures

Primary Outcomes (1)

  • Extraction Socket Healing Assessed Using the Landry, Turnbull and Howley Healing Index

    Extraction socket healing will be assessed using the Landry, Turnbull and Howley Healing Index, ranging from 1 (very poor healing) to 5 (excellent healing). Higher scores indicate better wound healing. Scores will be compared among the curcumin spray, chlorhexidine spray, and standard postoperative care groups.

    postoperative 7. and 14. days

Secondary Outcomes (5)

  • Postoperative Pain Intensity

    Postoperative days 1, 3, 5, and 7.

  • Change in Extraction Socket Wound Size

    Day 0 following extraction and postoperative days 7 and 14.

  • Change in Salivary Interleukin-1 Beta Concentration

    Before extraction (day 0) and postoperative days 2 and 7.

  • Change in Salivary Tumor Necrosis Factor Alpha Concentration

    Before extraction (day 0) and postoperative days 2 and 7.

  • Change in Salivary Prostaglandin E2 Concentration

    Before extraction (day 0) and postoperative days 2 and 7.

Study Arms (3)

Curcumin Topical Spray

EXPERIMENTAL

Participants will receive a Curcuma longa-containing topical spray applied to the extraction site as two sprays twice daily for 7 days, in addition to standard postoperative care.

Dietary Supplement: Curcumin Topical Spray

Chlorhexidine Topical Spray

ACTIVE COMPARATOR

Participants will receive a 0.12% chlorhexidine topical spray applied to the extraction site as two sprays twice daily for 7 days, in addition to standard postoperative care.

Drug: Chlorhexidine Topical Spray

Standard Postoperative Care

NO INTERVENTION

Participants will receive standard postoperative care following tooth extraction without the use of an additional topical spray.

Interventions

Curcumin Topical SprayDIETARY_SUPPLEMENT

A commercially available Curcuma longa-containing topical spray (Minerelax®) will be applied directly to the extraction site as two sprays twice daily for 7 days following tooth extraction, in addition to standardized postoperative care.

Curcumin Topical Spray

0.12% chlorhexidine topical spray administered to the extraction site as two sprays twice daily for 7 days.

Also known as: Chlorhexidine 0.12% Topical Spray
Chlorhexidine Topical Spray
