Completed

• Conditions: Impacted Third Molar Tooth

• Registration Number: NCT03894722
• Lead Sponsor: Cansu Gül Koca

Brief Summary

The aim of the present study was to evaluate the effects of different concentrations of povidone iodine (PVP-I) on postoperative swelling and trismus when used as a coolant and irrigation solution during the surgical removal of impacted mandibular third molars.

Primary Outcome Measures

Name	Time	Method
Postoperative Facial Swelling (assessed 3 facial lines (in millimeters) for determination of difference in facial contours before and after surgery)	Preoperative (on the day of surgery)- postoperative 2nd day-postoperative 7th day	For the assessment of facial swelling, three facial lines (in milimeters) were measured with a digital tape on the operated side using following (4) landmarks: the external canthus of the eye, the gonion angle, the lower border of the tragus, soft pogonion and the mouth commissure; Facial Lines between: 1. the external canthus of the eye- the gonion angle; 2. the lower border of the tragus-the mouth commissure; 3. the lower border of the tragus- soft pogonion
Postoperative Trismus (difference in interincisal distance at the maximal mouth opening (in millimeters) before and after surgery)	Preoperative (on the day of surgery)- postoperative 2nd day-postoperative 7th day.	The degree of trismus was assessed by measuring the distance between upper and lower incisal borders of the central incisors with a digital caliper.
