ABSTRACT


Purpose: The Aim Of This Study Was To Assess The Anatomical Variations Of The Nasopalatine Canal (shape, Length, Diameter, Inclination Of The Canal, Thickness Of Labial Bone, Distance Between The Canal And Upper Central Incisors) In Adult Egyptian Normal Population In Both Sexes Using Cone Beam Computed Tomography. Patients And Methods: 54 Participants Were Included In The Study (27males And 27 Females) Where They Were Indicated For CBCT Scanning For Purposes Rather Than Any Pathological Condition In The Anterior Maxilla. All The Participants Were Free Of Any Systemic Disease Affecting Bone Density And Shape As Well As Absence Of Any Pathological Lesions Or Fractures. Canal Morphology And Measurements Of The Canal Dimensions, Inclination And Its Relation With The Central Incisors Were Statistically Analyzed.

Results: The Morphology Of The NP Canal Showed The Highest Score Recorded For Y-shaped Canal; 31 (57.41%) Followed By Two Canals; 12 (22.22%) While The Lowest Score Recorded For Single Canal; 11 (20.37%) In The Coronal Views. It Was Found That Canal Length In Males Recorded Statistically Significant Higher Mean (9.477�1.85mm) Than Females (8.151�1.79mm) With A Total Length Mean Value (8.814�0.66mm). The Dimensions Of The Canal Showed In The Sagittal Cuts The Total Mean Value (3.307�0.18mm) Of The NP Foramen , Canal Recorded Total Mean Value (2.695�0.04mm) While Incisive Foramen Recorded Total Mean Value (3.557�0.04mm) With No Statistically Significant Differences Between Males And Female.

Conclusions: CBCT Is A Valuable Tool To Record The Morphology And Measurements Of The Nasopalatine Canal Where The Gender Showed Influence On The Recorded Findings Of This Study. In Egyptian Population, The Form Of The NP Canal Is Variable, Predominantly Hourglass Or Cylinder Shaped Laterally And Frontally They Are Mainly Y Shaped. For The Canal Length, It Was Noticed The Canal Was Shorter In Our Female Sample
