Objective: Theaim of this study was to compare the relationship between the morphology andthe morphology of sella tursica in 20 upper teeth.Materials andMethods: The material of this study was divided into 3 skeletal groups(classes 1, 2 and 3) of 151 individuals (67 males, 84 females, mean age 19.02 ±1.62) on panoramic and lateral cephalometric films. Variations in differentmorphologies due to Sella tursica bridging in lateral cephalometric films ofindividuals were evaluated.Results:One-Way ANOVA and Tukey multiple comparison tests were used to evaluate thegroups. There was no statistically significant difference between the skeletalgroups whether the maxillary third molar teeth were unilateral or bilateral. Onthe other hand, unilateral buried 20 year old females were found to bestatistically significant in the normal morphology of sellan among the groupsdepending on the morphology.Conclusion:Unilateral or bilateral unilateral maxillary third molars revealed nosignificant difference in terms of sella tursica morphology. In our study,normal variation of the most common sella tursica was observed in individualswith different skeletal anomalies.Objective: To evaluate the relationship between the morphological variations of sella turcica and maxillary third molar teeth impaction. Material and Method: The material of this study consisted panoramic radiographs and lateral cephalometric radiographs of 170 individuals (79 men, 91 women, mean age 19.02 ± 1.62) (Class I, 79; Class II, 71; Class III, 20). Individuals, included in this study, had impacted maxillary third molars unilaterally (n = 121) or bilaterally (n = 49). The variations of the sella turcica morphology evaluated in 6 different sub-groups on the individual lateral cephalometric radiographs. And the unilateral or bilateral impaction was investigated in terms of skeletal anomaly. Chi-Square analysis comparison tests were used to evaluate the groups. Results: 170 individuals with impacted maxillary third molar, 91 were female and 79 were male. There is no statistical difference between them in terms of unilateral and bilateral impacted teeth (p> 0.05). Of the 170 molar cases impaction in total, 79 are Class I, 71 are Class II, and 20 are Class III. There is no statistical difference between unilateral and bilateral buried cases in facial skeletal classification (p> 0.05). In this study, which included 170 individuals, when the impacted teeth were evaluated as total, the 2nd sella variation was observed in the individuals in this study (170/79) (46.5%). This is statistically significant (p <0.001). The most evident sella variation in unilateral 121 impacted molar is 2 (121/69) (57%). This is followed by the sella 1, sella 4, sella 6 variations, respectively. In the bilateral 49 embedded molar, the prominent sella variation is 6 (49/21) (42.9%). This is followed by the sella 4, sella 2, sella 1 variations, respectively. However, these are not statistically significant (p> 0.05). Conclusion: Sella 2 variation is the one most associated with impaction. Bilateral maxillary third molar impaction is more common in female individuals with Class II malocclusion than in male individuals.
