ABSTRACT:

Objectives: We aimed in this analysis to interrogate the importance of dental examination using Denta Scan for observing the proximity of upper jaw teeth roots and floor of sinus through dental examination. Study Design: A retrospective and randomized study Duration: This analysis was started from January, 2018 to December, 2018 with the duration of 12 months at the Dental Unit of Liaquat University Hospital, Hyderabad. Methodology: Dental examination of 60 cases of maxillary first premolar and second molar was performed. The relativity of maxillary sinus tooth root is categorized in four categories of dental examination. Proximity of sinus root and floor, alveolar cortical plate and the root’s density was observed and evaluated. Results: Dental examinations of the 60 cases in which female and males were 26 and 34 respectively with range of 14 to 18 years of age were observed through this analysis. Category 0 association was very usually observed in the 1st and 2nd PM, while through the 1st and 2nd MM category 1 association was observed usually. The average proximity from the maxillary sinus floor to the root was maximum for the molars palatal root and the premolar oral root. Although it was minimum for the mesiobuccally root of upper jaw 1st molar and the 2nd premolar palatal root. The proximity in the association of root of teeth and upper jaw sinus from right to left was not expressive analytically where p-value is greater than 0.001, the association among various categories was vital analytically where p-value is greater than 0.001. Radix buccalis of upper jaw 1st PM and the mesiobuccally root of upper jaw 1st molar were observed mostly near to the cortical plate. The distobuccal root of upper jaw 3rd molar seen distant from the cortical plate. Including the four vertical associations, analytically vital variation was observed in the density of bone around the roots. Conclusion: As a difference between other upper jaw posterior roots of teeth,the density of bone was constantly slighter in the maxillary PM and MM. Anatomical association raised the information and directed us for the next diagnosis of absolute preoperative preparation. During execution of the major oral operative method prevented the evaluated casual complexities. Key words: Maxillary, sinus floor, anatomy.
