Antibiotic Therapy in Impacted Mandibular Third Molar Surgery

This study compared three antibiotic approaches in healthy young adults undergoing surgical removal of impacted lower wisdom teeth: a single dose of antibiotics before surgery, antibiotic treatment after surgery, and no antibiotics. Participants had similar impacted lower wisdom teeth on both sides and underwent surgery in two separate sessions. The study evaluated postoperative pain, facial swelling, mouth opening, and changes in blood markers related to inflammation, including C-reactive protein, erythrocyte sedimentation rate, procalcitonin, and white blood cell counts. The aim was to determine whether antibiotic use before or after surgery affected postoperative recovery and systemic inflammatory responses compared with no antibiotic use.

Chlorhexidine Versus Normal Saline Socket Irrigation for Prevention of Dry Socket After Lower Wisdom Tooth Extraction

Dry socket, also called alveolar osteitis, is a painful complication that can occur after tooth extraction, particularly following removal of impacted lower wisdom teeth. It occurs when the blood clot that normally forms in the extraction socket is lost or breaks down, resulting in pain and delayed healing. This study will compare two solutions used to irrigate the extraction socket immediately after removal of an impacted lower wisdom tooth: normal saline and chlorhexidine. The study will determine whether immediate socket irrigation with chlorhexidine reduces the frequency of dry socket compared with normal saline. A total of 174 eligible patients undergoing surgical extraction of impacted lower wisdom teeth will be randomly assigned to receive either normal saline or chlorhexidine for immediate post-extraction socket irrigation. Participants will not be informed which irrigation solution they receive. The extraction will be performed by a single surgeon, and postoperative assessment will be performed by a co-researcher. Participants will be assessed for signs and symptoms of dry socket on postoperative days 2, 3, and 5. The occurrence of dry socket will be determined using predefined clinical criteria, including pain, trismus, halitosis, gingival inflammation, exposed or bare bone, radiating pain, and ipsilateral lymphadenopathy. The study will compare the frequency of dry socket between the chlorhexidine and normal saline groups. The findings may help determine whether chlorhexidine is more effective than normal saline for reducing the occurrence of dry socket after surgical extraction of impacted lower wisdom teeth.

Bone Defects Reconstruction After Dentigerous Cyst Enucleation With Autogenous Demineralized Dentin Matrix- ADDM and Advanced Platelet-Rich Fibrin- A-PRF.

This prospective clinical study evaluates bone healing following dentigerous cyst enucleation associated with impacted mandibular third molar extraction. The study compares spontaneous blood clot healing, Advanced Platelet-Rich fibrin (A-PRF), and A-PRF combined with Autogenous Dentin Demineralized Matrix (ADDM). Bone healing is assessed as the primary outcome, while postoperative pain intensity assessed using the Numerical Rating Scale (NRS) with graphical representation represents a secondary outcome. The study aims to determine whether the use of A-PRF or A-PRF combined with ADDM improves postoperative healing outcomes compared with spontaneous blood clot healing.

Evaluating The Use of CGF Made Gel in Mandibular Extraction Sites of Lower Impacted 3rd Molars.

The goal of this clinical trial is to learn if Concentrated Growth Factor (CGF) Gel help improve bone healing and reduce pain after the surgical removal of impacted lower third molars. The study aims to answer the following: Does packing CGF Gel into the extraction site improve bone density? Does the use of CGF Gel reduce postoperative pain for the patient? Researchers will evaluate the healing outcomes of patients receiving this treatment in a prospective case series study. Because this is a case series, all participants will receive the CGF Gel intervention rather than being compared to a placebo group. Participants in this study will: Undergo a blood draw to create the autologous CGF Gel from their own growth factors. Undergo the surgical extraction of an impacted lower third molar under local anesthesia. Have a CGF Gel placed in the extraction socket immediately following the tooth removal. Report their pain levels using a numeric scale on Day 1, Day 3, and Day 7 after surgery. Return for a follow-up CBCT scan three months after the procedure to evaluate bone density changes.

Evaluation of the Use of CGF Based Sticky Bone Packed in Fresh Odontectomy Site of Impacted Lower 3rd Molars

This clinical study aims to evaluate the effectiveness of Concentrated Growth Factor (CGF)-based sticky bone in enhancing bone healing after surgical removal of impacted mandibular third molars. Surgical extraction of impacted lower third molars is one of the most common procedures in oral and maxillofacial surgery and is often associated with postoperative complications such as pain, swelling, delayed healing, and bone defects within the extraction socket. CGF is an autologous platelet concentrate derived from the patient's venous blood through a specific centrifugation process. It contains a high concentration of growth factors that play a key role in angiogenesis, tissue regeneration, and bone formation. When combined with particulate bone graft material, CGF forms a cohesive structure known as "sticky bone," which can provide both biological stimulation and structural support for bone regeneration. In this study, CGF-based sticky bone will be placed into the fresh extraction socket immediately after surgical removal of the impacted mandibular third molar. Participants will be followed clinically and radiographically over a defined postoperative period. Clinical parameters such as pain intensity, soft tissue healing, and postoperative complications will be assessed, while radiographic analysis will be used to evaluate bone density and bone regeneration within the extraction site. The findings of this study may contribute to improving regenerative techniques in oral and maxillofacial surgery and provide evidence regarding the potential benefits of CGF-based sticky bone in enhancing postoperative healing and bone regeneration following third molar extraction.

Evaluating The Use of CGF Made Plugs in Mandibular Extraction Sites of Lower Impacted 3rd Molars.

The goal of this clinical trial is to learn if Concentrated Growth Factor (CGF) plugs help improve bone healing and reduce pain after the surgical removal of impacted lower third molars. The study aims to answer the following: Does packing CGF plugs into the extraction site improve bone density? Does the use of CGF plugs reduce postoperative pain for the patient? Researchers will evaluate the healing outcomes of patients receiving this treatment in a prospective case series study. Because this is a case series, all participants will receive the CGF plug intervention rather than being compared to a placebo group. Participants in this study will: Undergo a blood draw to create the autologous CGF plug from their own growth factors. Undergo the surgical extraction of an impacted lower third molar under local anesthesia. Have a CGF plug placed in the extraction socket immediately following the tooth removal. Report their pain levels using a numeric scale on Day 1, Day 3, and Day 7 after surgery. Return for a follow-up CBCT scan three months after the procedure to evaluate bone density changes.

Effect Of Electroacupuncture With Local Anesthesia On Pain And Stress During Impacted Lower Third Molar Surgery

This randomized controlled trial investigates the effect of electroacupuncture as an adjunct to local anesthesia on perioperative pain and stress during ambulatory surgical extraction of impacted lower third molars. Participants will be randomized into three groups: electroacupuncture, sham acupuncture, and control. Pain intensity and perceived stress will be assessed using validated scales, while biological stress and nociceptive markers (salivary cortisol, alpha-amylase, and substance P), as well as hemodynamic parameters (blood pressure and heart rate), will be measured. The study aims to provide an integrated evaluation of the effects of electroacupuncture on subjective, biological, and physiological indicators of perioperative response in oral surgery.
