This randomized, double-blinded clinical trial was designed to evaluate the effects of a bioactive mineral-ionic mouthrinse (THERAVEX® Total Oral Care Plus) on postoperative healing and patient comfort following simple tooth extraction. Tooth extraction is one of the most common dental procedures and is frequently associated with postoperative pain, inflammation, and delayed soft tissue healing. Conventional mouthrinses such as chlorhexidine are widely used for their antimicrobial properties; however, alternative approaches aimed at supporting the physiological healing process are increasingly being investigated.
A total of 94 systemically healthy patients requiring simple tooth extraction were enrolled and randomly allocated into three parallel groups receiving either a bioactive mineral-ionic mouthrinse, chlorhexidine 0.12%, or normal saline as postoperative oral rinses. Participants and investigators were blinded to group allocation throughout the study period.
The primary objective of the study was to assess early soft tissue healing of the extraction socket using standardized clinical measurements of buccolingual (BL) and mesiodistal (MD) socket dimensions at different postoperative time points. Secondary objectives included the evaluation of postoperative pain using a visual analog scale (VAS), as well as clinical assessment of tissue response during the healing period.
The study aims to investigate whether a bioactive mineral-ionic oral rinse may serve as a supportive postoperative strategy for enhancing early wound healing and improving patient-reported comfort after dental extraction procedures
Tooth extraction is one of the most frequently performed procedures in clinical dentistry and is commonly associated with postoperative discomfort, inflammation, and temporary impairment of oral function during the healing period. Early soft tissue closure and patient comfort are important factors influencing postoperative recovery and overall treatment experience.
Postoperative oral rinses are routinely prescribed following extraction procedures to support oral hygiene and reduce local microbial accumulation. Chlorhexidine-based mouthrinses are widely used due to their antiseptic properties; however, interest has increased in alternative approaches that may additionally support the biological processes involved in tissue repair.
Bioactive mineral-ionic formulations have been proposed as supportive agents capable of modulating the local wound environment through physicochemical mechanisms that may contribute to tissue stabilization and postoperative comfort. The present study was designed to clinically investigate the postoperative use of a bioactive mineral-ionic oral rinse in patients undergoing simple tooth extraction.
This study was conducted as a randomized, double-blinded, parallel-group clinical trial comparing a bioactive mouthrinse with commonly used postoperative rinsing approaches. Clinical follow-up evaluations were performed during the early healing phase after extraction in order to assess tissue response and patient-reported postoperative experience under standardized clinical conditions.
The purpose of this investigation is to further explore the potential role of bioactive oral care strategies as supportive postoperative adjuncts in routine dental extraction procedures.

Sterile isotonic saline solution used as a control intervention. Participants were instructed to rinse according to the study protocol.
Chlorhexidine gluconate solution (commonly 0.12%) used as an antimicrobial oral rinse following standard postoperative instructions.
A bioactive mineral-based oral rinse designed to support postoperative oral tissue healing. Participants followed the same rinsing protocol as other groups.
Early Soft Tissue Healing of the Extraction Socket
Assessment of early postoperative soft tissue healing following tooth extraction using clinical measurements of buccolingual (BL) and mesiodistal (MD) socket dimensions. Measurements will be performed at baseline (Day 0), Day 3, and Day 7 using standardized periodontal measurement techniques to evaluate dimensional changes during the healing process.
Time frame: 7 days
Postoperative Pain Intensity
Assessment of postoperative pain intensity using a Visual Analog Scale (VAS) ranging from 0 to 10, where higher scores indicate greater pain intensity.
Time frame: 7 days
Soft Tissue Healing Percentage (3D Analysis)
Quantitative assessment of soft tissue healing using 3D intraoral scanning and digital analysis to measure the percentage of wound closure.
Time frame: Day 3 to Day 7 post-extraction
Clinical Soft Tissue Appearance
Clinical evaluation of soft tissue healing based on visual assessment of tissue closure, inflammation, edema, and overall wound appearance during follow-up visits.
Time frame: Day 3 and Day 7 post-extraction
Patient-Reported Postoperative Comfort
Assessment of patient-reported postoperative comfort and oral function during the healing period using standardized clinical follow-up questionnaires.
Time frame: Day 3 and Day 7 post-extraction.
