Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals aged 16 to 50 who need clinically indicated extraction of their wisdom teeth.

Probably not a fit

Patients who are pregnant, nursing, or have medical conditions that prevent safe extraction will not benefit from this study.

What this trial studies

This observational study aims to collect data and surgical waste tissue from individuals aged 16 to 50 who require third molar extraction at the NIH NIDCR Dental clinic. Participants will undergo a screening visit, a surgery visit for tooth extraction, and a follow-up visit for post-operative evaluation. The collected specimens will be used for research to enhance understanding of oral health and improve dental surgical skills. The study seeks to enroll a convenience sample of up to 10,000 subjects to gather generalizable knowledge about tooth diseases.

Why it matters

Potential benefit: If successful, this study could lead to improved oral health practices and enhanced surgical techniques for dentists.

How similar studies have gone: While this approach of collecting surgical waste for research is not novel, it has shown potential in enhancing dental education and research outcomes in similar studies.

Who can join: the full rules

Show full inclusion / exclusion criteria
* INCLUSION CRITERIA:
* Ages greater than or equal to 16-50 years
* Clinical evidence of need for third molar extraction as determined by medical, dental, and radiographic evaluation by a NIDCR oral surgeon
* Willing to allow for the collection of extracted waste tissue (e.g., teeth, alveolar bone, excessive gingival tissue) to be used for research
* In good general health as defined by the American Society of Anesthesiologists (ASA) status I or II
* Able to understand and sign an informed consent

EXCLUSION CRITERIA:

* Pregnant or nursing women
* Unable to have third molar extraction as determined by NIDCR surgeon/dentist, due to medical conditions (beyond ASA I or II), complexity of the surgery, or history that precludes safe outpatient conscious sedation. These clinical decisions will be based on the risks and benefits related to the surgery.
