Abstract
ABSTRACTBackground: The depth of the floor of the maxillary sinus is very important to be assessed radiographically prior tocommencing any dental procedure that may involve or be in a close proximity to the sinus to avoid unwanted postoperativecomplications. The aim of the present research was study the following: 1- Individual variation in the levelof the floor of the maxillary sinus in both dentate and edentulous alveolar ridges. 2- The relation between the level ofthe floor of the maxillary sinus and the age, sexMaterials and methods: Two hundred alveolar ridges (154 dentate and 46 edentulous) were studied by viewing 100panoramic radiographs.Results: They were as follows:a-In dentate ridges, the average level of the floor of the maxillary sinus was 10.36 mm (S.D. 3.51), results fell in thefollowing categories: 30 % of the measurements were between 2-8mm. 58.44 % between 8.5-14.5mm. 11.04 %between 15-21 mm.b- In edentulous ridges, the average level of the floor of the maxillary sinus was 6.99 mm (S.D. 3.49), results fell in thefollowing categories: 67.39% of the measurements were between 2-8mm. 30.43 % between 8.5-14.5mm. 2.17 %between 15-21mm.Conclusion: This study found that there is relation between the depth of the maxillary sinus floor and the age of thepatients in dentate alveolar ridges while there is no relation in edentulous ridges, while There is no relation betweenthe depth of the maxillary sinus floor and the sex in dentate alveolar ridges while there is relation in edentulous ridges.There is difference between the sexes in alveolar ridge resorption after tooth loss.Key words: Floor of maxillary sinus.
