Objective: The
aim of this study was to compare the relationship between the morphology and
the morphology of sella tursica in 20 upper teeth.

Materials and
Methods: 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 different
morphologies due to Sella tursica bridging in lateral cephalometric films of
individuals were evaluated.

Results:
One-Way ANOVA and Tukey multiple comparison tests were used to evaluate the
groups. There was no statistically significant difference between the skeletal
groups whether the maxillary third molar teeth were unilateral or bilateral. On
the other hand, unilateral buried 20 year old females were found to be
statistically significant in the normal morphology of sellan among the groups
depending on the morphology.

Conclusion:
Unilateral or bilateral unilateral maxillary third molars revealed no
significant difference in terms of sella tursica morphology. In our study,
normal variation of the most common sella tursica was observed in individuals
with different skeletal anomalies.

Relationship of Impacted Maxillary Third Molar Teeth with Sella Turcica Morphology

Öz

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.
