Assessment of the Relationship between Sella Turcica Morphology and Delayed Dental Age

Abstract

The purpose of this study was to evaluate the relationship between sella turcica morphology and delayed dental age. In total, 389 participants under 16 years old were selected. Dental age was evaluated by the Demirjian method and age discrepancy (AD), the value subtracted from dental age to chronological age, was calculated. The participants were divided into 8 groups based on the sella turcica type. Bridging ratio (BR) was defined as interclinoid distance divided by sella turcica length to determine the degree of sella turcica bridging (STB) and the participants were classified into 4 groups by BR. The data were statistically analyzed using the Kruskal Wallis test and the Mann Whitney test. Some groups with sella turcica abnormality showed lower AD than that of the normal group and the AD differences varied from 4 months to 1.3 year. As the STB severity increased, AD decreased. AD differences varied from 7 months to 1.19 year. No distinct differences were observed in sella turcica type and STB groups according to sex. The results indicate that sella turcica morphology is associated with delayed dental age. Sella turcica can be used as a supplementary indicator to predict dental development.

Trends of conscious sedation in the Department of Pediatric Dentistry at the Dankook University Dental Hospital for 11 Years

“…Corresponding to this result, the number of males who visited pediatric dentistry was higher than that of females over the past 11 years, and the sex distribution of patients who underwent sedation also reflected this. Additionally, according to a study by Choi and Park in 2003, males showed higher anxiety than females in a dental environment, and according to a study by Boyar and Cross in 1997, the behavioral patterns of males before separation from their parents were worse than those of females [ 17 18 ]. Based on these results, it can be said that in the case of males, patients and dentists tend to prefer sedation.…”

Comparing the Temporal Aspects of Velopharyngeal Closure in Children with and without Cleft Palate

“…The current study found that high vowel contexts were more sensitive to temporal aspects of nasalization than low vowel contexts. Similarly, Cho et al [28] emphasized that high vowel contexts had more significant nasalization components than low vowel contexts [28]. Moreover, Kulak Kayikci and Ozgen [29] organized Turkish vowel contexts from high to low according to the mouth structures of 10 healthy adults using magnetic resonance imaging as follows: /i/, /ü/, /e/, /u/, /ı/, /ö/, /o/, and /a/.…”
