Primary malignant melanoma.

Malignant melanomas (MM) of the oral cavity are extremely rare, accounting for 0.2% to 8.0% of all malignant melanomas.

Evaluation of the effects of platelet-rich fibrin on bone regeneration in diabetic rabbits.

Objectives: This study aimed to investigate the effect of platelet-rich fibrin on bone regeneration in critical size defects in the calvaria of diabetic rabbits.

Study Design: In total, 40 male New Zealand rabbits, were divided into two groups a non-diabetic control group (Group A) and a diabetic experimental group (Group B). Two bicortical circular defects 15 mm in diameter were created in the parietal bone of each animal.

Assessment of heat generation during implant insertion.

Statement Of Problem: Many studies have investigated the heat generated during implant preparation, but data are needed to better predict heat generation during implant insertion.

Purpose: The purpose of this study was to measure the heat generated during insertion of an implant at speeds of 30, 50, and 100 rpm, and with manual insertion.

Material And Methods: Sixty-four uniform fresh bovine femoral cortical bone specimens were used.

Comparison of heat generation during implant drilling using stainless steel and ceramic drills.

Purpose: The purpose of this study was to compare the heat generated from implant drilling using stainless steel and ceramic drills.

Materials And Methods: A total of 40 fresh bovine femoral cortical bone samples were used in this study. A constant drill load of 2.

Effect of surgical drill guide on heat generated from implant drilling.

Purpose: The purpose of this study was to evaluate the heat generated in bone by 2 implant drill systems in vitro with and without using surgical drill guides.

Materials And Methods: Temperature was measured with K type thermocouple in vitro using the bovine femoral cortical bone model. A constant drill load of 2.

Influence of different suturing techniques on periodontal health of the adjacent second molars after extraction of impacted mandibular third molars.

Objective: The objective of this randomized controlled trial was to compare the effects of different suturing techniques (simple loop suture vs. anchor suture) on the periodontal health of the adjacent second molars after impacted mandibular third molar extraction.

Study Design: Fifteen patients with bilaterally identical impacted mandibular third molars were used.

A comparison of injection pain with articaine with adrenaline, prilocaine with phenylpressin and lidocaine with adrenaline.

Objective: The objective of the present study was to investigate the pain on injection of articaine with adrenaline, prilocaine with phenylpressin , and lidocaine with adrenaline.

Study Design: The study sample was comprised of 497 consecutively seen patients received 497 maxillary buccal infiltration injections or inferior alveolar block injections of 4% articaine with 1:200.000 adrenaline, 3% prilocaine with 1.

Comparison of the Wand with a conventional technique.

Objective: The objective of the present study was to compare the Wand computer-controlled anesthetic delivery system with a conventional technique as to pain of needle insertion and the pain during injection according to the patient's dental anxiety levels.

Study Design: The study sample comprised 52 healthy patients about to undergo routine tooth extraction. A dental anxiety scale was used to determine anxiety levels before anesthetic administration.
