What the trial is, and whether it could suit you
This study investigates whether the intraoperative application of a specialized regenerative gel (Emdogain®) can improve the periodontal health of the mandibular second molar by preventing or reducing the formation of tissue defects after the surgical removal of an adjacent impacted lower wisdom tooth.
Surgical extraction of a lower wisdom tooth frequently leaves a deep pocket or a permanent hard and/or soft tissue defect on the back side of the neighboring second molar. This defect compromise the surrounding tissues and predispose the healthy second molar to future complications like root caries, dentin hypersensitivity, or localized gum disease. While most existing treatments address these defects after they have formed, this trial evaluates a site-specific preventive approach during the extraction process itself.
The study will involve 70 systemically healthy adults (ages 18-45) req

📋 Eligibility rules (as published)
Inclusion Criteria:
* Healthy adult patients aged 18 to 35 years old (ASA I or II).
* Presence of an asymptomatic, partially or fully impacted mandibular third molar requiring surgical extraction.
* The third molar impaction must be mesioangular or horizontal, with its crown in direct physical contact with the adjacent second molar, as assessed by a preoperative panoramic radiograph.
* The adjacent mandibular second molar must be vital, fully erupted, and structurally sound (free of extensive dental caries or prosthetic crowns).
* Patients must demonstrate an adequate level of overall oral hygiene and gingival health (e.g., Full-Mouth Plaque Index \< 20% and Full-Mouth Bleeding Score \< 20% following initial prophylaxis and oral hygiene instructions).
* Willingness to comply with postoperative instructions and adhere to the scheduled follow-up visits.
* Ability to understand the study procedures and voluntarily sign the informed consent form.
Exclusion Criteria
* Presence of systemic diseases or conditions that could compromise wound healing or periodontal health (e.g., uncontrolled diabetes mellitus, autoimmune disorders).
* Current or recent use of medications known to affect bone metabolism or wound healing (e.g., bisphosphonates, long-term systemic corticosteroids, immunosuppressants).
* History of heavy smoking (e.g., \>10 cigarettes per day) or use of smokeless tobacco products.
* Pregnant or lactating females.
* Diagnosis of periodontitis (Stage II, III, or IV) affecting the remaining dentition, excluding the localized defect associated with the impacted third molar.
* Presence of active acute infection (e.g., purulent pericoronitis) or radiolucent pathologic lesions extending beyond the normal follicular space (e.g., dentigerous cysts) that would significantly alter the baseline bony defect morphology.
* Known allergy or hypersensitivity to any of the medications utilized in the surgical or postoperative protocol (e.g., local anesthetics, prescribed antibiotics, or analgesics).
* Previous orthodontic treatment utilizing bands on the mandibular second molars that could have affected the periodontal attachment.
