Assessing the Relationship between Sella Turcica Morphology and Dental Age with Dental Anomalies: A Cephalometric and Orthopantomographic Study

and type B, which entails an enlargement of the sella turcica bridge, were described by Becktor et al. 3 In cephalometric analyses of a healthy sample, full sella turcica bridging ranges in frequency between 1.10 and 11.7%.Studies by Kucia et al. 2 showed that those with sella turcica abnormalities show notably more retruded mandibular alveolus and angles of incisor inclination than those with a normal.Comparably, Motwani et al. discovered that malocclusion is linked to sella turcica abnormalities.Patients with oral abnormalities have shown a greater frequency of sellar bridging; rates range from 6.45 to 33.30%.Recent meta-analysis has reiterated a significant relationship between IntroductIonAnatomically, the sella turcica forms a saddle-like concavity on the superior aspect of the sphenoid bone within the cranial cavity.This framework comprises the S-point, which, in the sellar area, has a mid-position and is an essential anatomical landmark in orthodontics, as it helps to evaluate craniofacial development.Comprising three lobes, the anterior (adenohypophysis), the intermediate lobe, and the posterior (neurohypophysis), the pituitary fossa housed inside the sella turcica fits the pituitary gland.Dysfunction of the pituitary gland can alter sellar morphology and impair hormonal regulation, including secretions of prolactin, thyroid-stimulating hormone (TSH), growth hormone (GH), and follicle-stimulating hormone (FSH).Together with the usual anatomy of the sella turcica, Axelsson et al. noted five types of sellar irregularities: bridging, oblique anterior wall, double contour of the floor, sella turcica irregularity notching in the posterior part of the dorsum sellae, and pyramidal-shaped dorsum sellae. 1 Three further variants of sellar dysmorphology were also presented by Kucia et al. 2 : (1) oblique floor contour, (2) hypotrophic posterior clinoid process, and (3) hypertrophic posterior clinoid process. 2 Among these, sella turcica bridging is the most often investigated anomaly.Characteristic of bridging is the junction of the anterior and posterior clinoid systems.Type A, a visible fusion akin to a ribbon,
