Proximity of maxillary posterior teeth roots to maxillary sinus and adjacent structures using Denta scan®

AIM: . MATERIALS AND METHODS: images (based on the classification by Jung in 2009). The distance between the sinus floor and root, and the bone thickness between the root and alveolar cortical plate will be measured and analyzed. CONCLUSION: The buccal root of the maxillary molars was more commonly protruded into the maxillary sinus. Among the roots of maxillary posterior teeth, mesiobuccal root of first molar and palatal root of second premolar were found in close proximity to the floor of maxillary sinus. The bone thickness on the buccal aspect to the root was significantly thinner in the maxillary first premolar and maxillary first molar as compared to other maxillary posterior teeth roots. CLINICAL SIGNIFICANCE: Knowledge of anatomical relationship between the maxillary posterior teeth and maxillary sinus guides us not only in proper preoperative treatment planning but also avoids the possible complications encounter while performing the minor oral surgical procedures involving maxillary posterior teeth, which are close to the maxillary sinus.
