The general objective of this split-mouth study is to analyze the osteogenic action of BTCP during the bone regeneration process following the extraction of impacted mandibular third molars.
The proposed protocol is a multicenter clinical trial aimed at analyzing the osteogenic action of a medical device based on beta-tricalcium phosphate (hereinafter BTCP) in the bone regeneration process following the extraction of impacted mandibular third molars. The specific objectives of the study include a comparative analysis of clinical and radiological variables between a control group and a study group. Inclusion criteria for study subjects include being of legal age, providing informed consent, and requiring the extraction of both impacted mandibular third molars, among others. Exclusion criteria include the presence of severe mental disorders or medical contraindications for tooth extraction. The study involves a total of 60 third molars from 30 patients, divided into a control group and a study group. Data will be collected regarding patient demographics, the surgical procedure, and the bone regeneration assessment. The surgical procedure involves selecting patients with similarly complex third molars, followed by tooth extraction and the placement of BTCP in the study group or a standard material in the control group. Clinical follow-up will be conducted during the first 7 days, and radiological follow-up will take place over the following 6 months to evaluate bone regeneration. Patients will receive compensation for their participation in the study, which includes medical consultations, phone follow-ups, examination time, completion of questionnaires, and training in self-assessment.

The description of the intervention for BTCP in the study involves the application of this substance to promote bone regeneration following the extraction of impacted mandibular third molars. BTCP is indicated for the treatment of segmental and cavitary bone loss, aesthetic repairs, and bone augmentations (such as inlay or onlay grafts); for filling dental alveolar bone; for dental implant placement; and for the stabilization of osteotomies and prostheses in dentistry.
The intervention description for Bio-Oss in the study involves the application of this standard material to promote bone regeneration following the extraction of impacted mandibular third molars. Bio-Oss is a commonly used xenograft material known for its osteoconductive properties.

Bone Regeneration_Reduction in radiolucent volume
This outcome measure involves assessing the degree of bone regeneration in the extraction socket following the extraction of impacted mandibular third molars. It will be evaluated through radiological imaging using CBCT scans at specified time points, including immediately post-extraction, at one month, three months, and six months post-extraction. Reduction in radiolucent volume within the extraction socket, indicating new bone formation (Hounsfield unit (HU)). High values mean more radiopacity and better regeneration.
Time frame: A) Immediately after extraction B) 1 month. C) 3 months. D) 6 months
Bone Regeneration_bone volume
This outcome measure involves assessing the degree of bone regeneration in the extraction socket following the extraction of impacted mandibular third molars. It will be evaluated through radiological imaging using CBCT scans at specified time points, including immediately post-extraction, at one month, three months, and six months post-extraction. Evaluation of bone volume within the extraction site over time (mm3). The increase in bone volume means better regeneration
Time frame: A) Immediately after extraction B) 1 month. C) 3 months. D) 6 months
Bone Regeneration_bone density
This outcome measure involves assessing the degree of bone regeneration in the extraction socket following the extraction of impacted mandibular third molars. It will be evaluated through radiological imaging using CBCT scans at specified time points, including immediately post-extraction, at one month, three months, and six months post-extraction. Changes in bone density within the regenerated bone tissue (Hounsfield unit (HU)) High values mean more radiopacity and better regeneration.
Time frame: A) Immediately after extraction B) 1 month. C) 3 months. D) 6 months
Bone Regeneration_Fractal dimension
This outcome measure involves assessing the degree of bone regeneration in the extraction socket following the extraction of impacted mandibular third molars. It will be evaluated through radiological imaging using CBCT scans at specified time points, including immediately post-extraction, at one month, three months, and six months post-extraction. Evaluation of bone morphology within the extraction site over time analyzing the fractal dimension (FD) FD can vary between 1 and 2, with 1 being a very simple fractal dimension (such as a straight line) and 2 being a more complex fractal dimension (such as a completely irregular surface)

Pain levels through visual analog scale
Assessment of pain experienced by participants using a visual analog scale (VAS) at various time points post-extraction. It comprehends values between 0-10, where 10 is the worst situation.
Time frame: 24 hours, 48 hours, 72 hours, and 7 days
Clinical Inflammation evaluating by presence/absence
Evaluation of postoperative inflammation around the extraction site using clinical examination and assessment tools (presence/absence). The presence of inflammation means the worst prognosis.
Time frame: 24 hours, 48 hours, 72 hours, and 7 days
Healing measured by healing index
The healing progress will be assessed using the Healing Index (HI) developed by Hamzani \& Chaushu (2018) and Landry (1988). The HI score ranges from 0 to 5, where 0 indicates poor healing and 5 indicates excellent healing. To ensure consistency and reliability in the assessment of healing, two independent researchers will evaluate the healing progress for all participants. The level of agreement between the researchers will be assessed using Cohen's Kappa index (Mandrekar, 2011). A Cohen's Kappa index value of 0.91 was achieved for the assessment of inflammation level, indicating a high degree of agreement. Similarly, agreement levels exceeding 0.90 were obtained across all HI levels, demonstrating a high level of concordance in the assessment of healing progress.
Time frame: 24 hours, 48 hours, 72 hours, and 7 days
Post-surgical complications evaluated by presence or absense
Monitoring and recording of any complications following the extraction procedure, such as alveolitis, trismus, infection, and hematoma (presence/absence). The presence of complications is related to a worse prognosis.
Time frame: 24 hours, 48 hours, 72 hours, and 7 days
Oral Health-related Quality of Life measured by OHIP-14 test
Assessment of the impact of treatment on patients' quality of life using validated instruments (OHIP-14). The higher the average value of the seven dimensions, the more negative the impact of oral health on the quality of life of an individual.Minimum of 0 points and maximum of 56 points. Lower scores: They indicate that the person experiences less impact of oral health problems on their quality of life. That is, they have fewer problems or feel less the impact of these problems in their daily lives. Intermediate scores: Suggest a moderate impact of oral health problems on quality of life. The person may experience some difficulties or discomfort related to their oral health, but they do not necessarily significantly affect their daily functioning. Higher scores: Indicate a significant impact of oral health problems on quality of life. The person may experience a wide range of problems that affect their general well-being, including pain, eating difficulties, sleep problems, etc.
