A correlative study of sella turcica bridging and dental anomalies related to size, shape, structure, number and eruption of teeth

Abstract

OBJECTIVE: The main objective of this study is to get a wider and clearer idea about the relationship between sella turcica bridging and the type of dental anomalies related to size, shape, number, structure and eruption of teeth. MATERIALS AND METHODS: For the present study, 50 pretreatment lateral cephalometric radiographs showing complete sella turcica bridging were retrieved from the 500 existing case records of patients. The control group consisted of 50 pretreatment lateral cephalograms without sella turcica bridging retrieved from the same case records by using simple random sampling. After collection of the samples, retrospective study was performed with the analysis of patient records to assess any associated dental anomaly in patients with sella turcica bridging and patients without sella turcica bridging. Shafer's classification of morphological variations in size, shape, structure, number and eruption of teeth was used to analyze and group the dental anomalies. RESULTS: The incidence of dental anomalies related to number and size of teeth was found to be higher in cases with sella turcica bridging. CONCLUSION: Lateral cephalogram is used by orthodontist routinely for diagnosis and treatment planning; it can be used as a prediction tool for dental anomalies as well. Early detection of skeletal anomalies can be used to forecast the presence of dental anomalies later in life, which will help the clinician to adopt preventive measures.

Sella turcica bridging as a potential diagnostic tool for dental anomalies: A retrospective cross-sectional study at university dental hospital

“…[ 19 20 21 22 ] The findings of our study are consistent with those of another research conducted in 2022, which states a significant association between occurrence of dental anomalies in number and size of teeth higher in cases with STB. [ 4 ]…”

“…Conducting comprehensive studies in this area would contribute to our knowledge of craniofacial development and improve our ability to diagnose and predict specific dental conditions. [ 4 ]…”

Exploring the association between PITX2, third molars agenesis and sella turcica morphology

“…Excessive ossification of the ligaments between the anterior and posterior clinoid processes of the sphenoid lead to the development of the bridge [ 34 ]. Interestingly, some authors reported that sella turcica bridging is likely to complement the diagnostic parameters to predict the susceptibility of some dental alterations [ 35 ], and was also associated with skeletal malocclusion, in which skeletal class III malocclusion presented more sella bridging [ 34 , 36 ].…”

Morphology of the Sella Turcica: A Meta-Analysis Based on the Results of 18,364 Patients

“…A total of 15,752 articles were initially found. After the removal of duplicates and irrelevant reports, a total of 91 articles matched the required criteria and were taken into consideration in this meta-analysis [ 1 , 2 , 9 , 12 , 13 , 14 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 ,…”
