Effectiveness of intra-oral botulinum toxin injection in comparison to the extra-oral approach on pain and quality of life in patients with myofascial pain: a randomized clinical trial.

Objective: To evaluate and compare the effectiveness of the ultrasound-guided intra-oral and extra-oral transcutaneous injection techniques on the clinical outcome variables in patients with myofascial trigger points within the masseter muscle.

Materials And Methods: This prospective randomized trial included 42 patients diagnosed with myofascial pain. Patients were randomly allocated into one of two groups based on the technique of trigger point injection: intraoral and extraoral injection technique groups.

Alveolar cleft reconstruction using bone marrow aspirate concentrate and iliac cancellous bone: A 12-month randomized clinical study.

Objective: This study aimed to compare the bone density and volume in patients with alveolar cleft reconstructions utilizing bone marrow aspirate concentrate with iliac graft versus iliac graft alone.

Material And Methods: Thirty-six patients with unilateral alveolar cleft were randomly allocated into either an intervention group receiving an iliac bone graft mixed with bone marrow concentrate or a control group receiving an iliac bone graft. Cone beam CT was obtained preoperative, 6 and 12 months postoperatively to assess the bone density of the graft and bone volume of the alveolar defect, and then, the bone loss ratio was calculated.

Diode laser in management of loss of taste sensation in patients with post-COVID syndrome: a randomized clinical trial.

Objective: Loss of taste (ageusia) is a symptom observed following recovery from COVID-19 infection. The loss of taste and smell sensation may negatively affect patients' quality of life (QoL). The present study aimed to evaluate the effectiveness of the Diode Laser in managing loss of taste sensation in patients with post-COVID syndrome versus the placebo.

The Effect of Local Melatonin Application Following the Removal of an Impacted Mandibular Third Molar.

Purpose: Pain, swelling, limitation of the mouth opening, development of intra-bony defects, and bone loss are common side effects of removing the impacted third molar. The purpose of this study was to measure the association of applying melatonin in the socket of an impacted mandibular third molar with osteogenic activity and the anti-inflammatory effects.

Methods: This prospective, randomized, blinded trial comprised of patients who required removal of the impacted mandibular third molar.
