A Randomized, Self Controlled Clinical Study of Hemostatic Efficacy of the HemCon Dental Dressing

Inclusion Criteria: * Patients requiring 2 or 4 3rd molar tooth extraction procedures. * Index pairing must reflect anatomically similar extraction locations, i.e., for 2 extractions both must be upper or both must be lower extractions. * Patients must be 14 years of age or older * Patients must be available for a minimum of one post operative evaluation to be scheduled at the time of the procedure approximately 7 days post surgery. Additional follow-up visits may be scheduled at the discretion of the surgeon based on the severity of particular patient cases or the patient's need for earlier follow-up. * Extraction sites do not require primary closure or suturing * Willingness and ability to provide informed consent/ assent for participation * Patients with seafood allergies * Patients who have discontinued the use of anticoagulant medications (e.g., aspirin, coumadin, Plavix, etc.) for a minimum of 3 days prior to their planned surgical visit. Exclusion Criteria: * Scheduled to undergo a surgical procedure other than 3rd molar tooth extractions * Scheduled to undergo 2 extractions whereby one is an upper 3rd molar and the other is a lower 3rd molar. These will not reflect a proper index pairing for statistical calculations and data analysis based on anatomical similarities. * Extraction procedures are expected to require primary closure or suturing of the HemCon® Dental Dressing within the oral wound. * Unable or unwilling to provide informed consent/ assent for participation as a subject * Patients who are currently taking anticoagulant medications (e.g., aspirin, coumadin, Plavix, etc.) or have discontinued their anticoagulant medications less than 3 days prior to their surgical visit. * Patients who are undergoing bisphosphonate therapy.
