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.
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.
The incidence of dental anomalies related to number and size of teeth was found to be higher in cases with sella turcica bridging.
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.
本研究的主要目的是更广泛、更清晰地了解蝶鞍桥接与牙齿大小、形状、数量、结构及萌出等方面的牙颌畸形类型之间的关系。
在本研究中，从500例患者的现有病例记录中检索出50张显示完整蝶鞍桥接的治疗前头颅侧位X线片。对照组由通过简单随机抽样从同一病例记录中检索出的50张无蝶鞍桥接的治疗前头颅侧位片组成。收集样本后，进行回顾性研究，分析患者记录，以评估有蝶鞍桥接和无蝶鞍桥接患者的任何相关牙颌畸形情况。采用Shafer对牙齿大小、形状、结构、数量及萌出的形态学变异分类方法对牙颌畸形进行分析和分组。
发现蝶鞍桥接病例中与牙齿数量和大小相关的牙颌畸形发生率更高。
正畸医生通常使用头颅侧位片进行诊断和治疗计划制定；它也可作为牙颌畸形的预测工具。早期发现骨骼异常可用于预测后期生活中牙颌畸形的存在，这将有助于临床医生采取预防措施。
