Incidental finding of two rare developmental anomalies: Fusion and dilaceration: A case report and literature review

Abstract

A number of developmental anomalies of morphology are there. However, as compared to the more common oral diseases like caries or periodontal problems, they account for a relatively lower number. When present, they may pose various problems of esthetic, function, malocclusion, or possible disposition to other oral problems. Hence, though rare, their timely diagnosis is very vital in proper treatment planning to avoid unseen complications during extractions, endodontic or orthodontic treatment. The present case is of a patient reporting with two very rare developmental anomalies, that is, fusion and root dilaceration, in contralateral sides of the same patient. To the knowledge of the author, reportedly it is the first such case. The terminologies, etiology, and epidemiology of both these anomalies are also discussed.

Dental anomalies in non‐syndromic orofacial clefts: A clinical approach

“…In the general population, the frequency of root dilaceration varies in different ethnic groups, between 0.3 and 27.2%, with no gender predilection. (Cao et al, 2021; Nabavizadeh et al, 2013; Sultan, 2015; Topouzelis et al, 2010; Weckwerth et al, 2016). However, in patients with NSOC, the prevalence ranged from 7.5% to 31.2% in CL; 6–29.6% in CLP and 8.3–26.3% in CP.…”

“…Root dilaceration can occur in both dentitions, less frequently in the primary dentition, with no gender predilection (Sultan, 2015). The diagnosis of root dilaceration is exclusively through imaging examinations (intraoral, extraoral, and CBCT radiographs).…”

“…Other authors consider root dilaceration only cases in which the angle formed between the crown and root is equal to or greater than 90° (Fuentes et al, 2018; Jarzadeh & Abbott, 2007; Malcić et al, 2006). Root dilaceration can occur in both dentitions, less frequently in the primary dentition, with no gender predilection (Sultan, 2015). The diagnosis of root dilaceration is exclusively through imaging examinations (intraoral, extraoral, and CBCT radiographs).…”

“…The diagnosis of root dilaceration is also extremely important for endodontics, as its lack of knowledge can lead to inadequate endodontic treatments and treatment failure (Nabavizadeh et al, 2013; Sultan, 2015). The evaluation of root curvatures is essential for the correct choice of the endodontic technique.…”
