Objective: To investigate the prevalence of dental anomalies in Chinese children with complete unilateral cleft lip and palate (UCLP).

Methods: Dental histories and radiographs of 244 Chinese children with UCLP were collected. The diagnosis of dental anomalies was based on panoramic radiographs before alveolar bone grafting. All patients were over 8 years old.

Results: In the UCLP group, 66.8% of the patients was presented with hypodontia. The maxillary lateral incisors were the most common teeth affected, followed by maxillary second premolars, mandibular incisors and mandibular second premolars. A total of 33.6% the patients was presented with dental malformation, most were microdontic laterel incisors. A total of 4.9% the patients was presented with hyperdontia. The supernumerary teeth were more frequently found in the cleft region. The prevalence of missing maxillary lateral incisor in the noncleft side was statistically different between genders, which was higher in male (P < 0.050). This group of Chinese children with UCLP demonstrated significantly higher prevalence of hypodontia, hyperdontia, and malformation on the cleft side than on the noncleft side (P < 0.01).

Conclusions: Hypodontia is the most common type of dental anomalies. The prevalence of dental anomalies is higher in the UCLP patients than in the normal population. Dental anomalies occur more frequently on the cleft side than on the noncleft side.

BCL11B is a Cys2-His2 zinc-finger (C2H2-ZnF) domain-containing, DNA-binding, transcription factor with established roles in the development of various organs and tissues, primarily the immune and nervous systems. BCL11B germline variants have been associated with a variety of developmental syndromes. However, genotype-phenotype correlations along with pathophysiologic mechanisms of selected variants mostly remain elusive.

SOX9 encodes an SRY-related transcription factor critical for chondrogenesis and sex determination among other processes. Loss-of-function variants cause campomelic dysplasia and Pierre Robin Sequence, while both gain- and loss-of-function variants cause disorders of sex development. SOX9 has also been linked to scoliosis and cancers, but variants are undetermined.

: The orthodontic management of pediatric patients with rare diseases, such as Ectodermal Dysplasia (ED) and Osteogenesis Imperfecta (OI), requires complex protocols due to dental anomalies in both the number and structure of teeth. These conditions necessitate a departure from traditional orthodontic approaches, as skeletal anchoring is often required because of these anomalies. A patient with ED, characterized by hypodontia and malformed teeth, presented with insufficient natural teeth for anchorage.

Mandibular gingival squamous cell carcinoma (SCC) is the second most common oral cancer after tongue cancer. As these carcinomas often invade the mandible early, accurately defining the resection extent is important. This report highlights the use of preoperative virtual surgery data, computer-aided design and manufacturing (CAD/CAM) technology, surgical guidance, and extended reality (XR) support in achieving highly accurate marginal mandibulectomy without recurrence or metastasis.
