Vertical relationships between the divergence angle of maxillary molar roots and the maxillary sinus floor: A cone-beam computed tomography (CBCT) study.

Aim: To assess the relations between the divergence angle of the maxillary molar roots and their proximity to the maxillary sinus floor using CBCT.

Method: This study comprised CBCT scans of the maxilla, including at least the inferior one-third of the maxillary sinus and at least one molar present in any quadrant with complete eruption and root formation. Evaluation included the vertical relations between the maxillary molar root apices and the maxillary sinus floor (MSF), and the root divergence was measured from the root apices to the floor of the pulp chamber.

Study of Lateral Wall Thickness of the Maxillary Sinus in Left and Right Sides for Female and Male: A Cross Sectional Retrospective Study Using Cone Beam Computed Tomography.

Background: Dental implants are considered the first option to replace missing teeth. Alveolar bone resorption gradually progresses following tooth extraction leading to loss of vertical bone dimension for implant placement. The lateral window approach is the most commonly used procedure to treat vertical bone loss.

Knowledge, Attitude, and Management of General Dentist toward Medication-related Osteonecrosis of the Jaws.

Background: Medication-related osteonecrosis of the jaw (MRONJ) is an intense negative drug response causing increasing bone destruction in the maxillofacial area of patients.

Aims And Objectives: To evaluate the knowledge and attitude of dental practitioner regarding risk factors of MRONJ in Saudi Arabia.

Materials And Methods: A cross-sectional, questionnaire survey was carried out in King Khalid Hospital, Al-Kharj among dental practioners.
