Abstract:

Purpose: The aim of this study is to assess the occurrence, type, and location of dental incidental findings with cleft lip and palate (CLP) prior to phase I orthodontic therapy, alveolar bone grafting, and related dental interventions

Methods: This was a retrospective radiographic and chart review evaluation for head and neck cone beam computerized tomography (CBCT) scans taken for non-syndromic CLP patients in the early mixed dentition stage between January 2010 - June 2023. Only subjects with CBCT scans taken prior to any alveolar bone graft procedure or phase I orthodontic therapy were included. Invivo 6 Software was used to view the images for the included subjects and screen them for aberrations in dental development including supernumerary teeth, teeth with atypical crown and/or root morphology, missing, ectopic, and impacted teeth. Age, gender, and severity of the cleft were extracted from the charts.

Results: We received a total of 65 patient charts, of which only 31 of the scans fit our inclusion criteria and were able to be viewed and evaluated. Of these scans, 10 of the patients had bilateral CLP and 21 had unilateral CLP. There were 30 patients (96.7%) that had some form of incidental finding noted. 83.9% of the patients presented with at least one congenitally missing tooth, 48.4% presented with some form of ectopic eruption, 38.4% presented with at least one supernumerary tooth, 12.9% presented with microdontia, and 9.6% presented with transposition.

Conclusions: Examining CBCT images of CLP patients to become aware of any dental findings is imperative when treatment planning for these patients as incidental dental findings were found to occur in a significant portion of the patients studied. Bilateral CLP patients showed the highest percentage of dental anomalies with 100% presenting with at least one finding. The majority of dental anomalies occurred on the side of the patient’s cleft with most being noted adjacent to the cleft itself. Congenitally missing teeth were the most common finding with the permanent lateral incisor on the side of the cleft the most common missing tooth.
