Tooth Abnormalities In Individuals With Unilateral Alveolar Clefts: A Comparison Between Sides Using Cone-Beam Computed Tomography

Unusual Indications of Teeth Transplantation: A Literature Review

Dental implants are one of the best valid tooth replacement options, though these are not always appropriate in growing young patients. Tooth autotransplantation can be indicated then. However, this is not the only scenario where dental transplantation can be indicated. This comprehensive literature review discusses a wide range of unusual indications of dental transplantation as reported throughout the medical literature. Surprisingly, these indications include management of some developmental dental anomalies, hypodontia, oroantral communications, alveolar clefts, deficient alveolar ridges, ectopic teeth, and maxillofacial injuries. Limited high-quality evidence in this field regarding most of these unusual indications warrants further research of high-quality design.

Tooth abnormalities associated with non-syndromic cleft lip and palate: systematic review and meta-analysis

OBJECTIVE

To evaluate the association between orofacial clefts (OFC) and tooth abnormalities (TA).

METHODS

We searched PubMed, Scopus, Web of Science, Cochrane Library, LILACS, and BBO, and in the gray literature and selected observational studies that evaluated the association between TA and OFC. The risk of bias was analyzed using the Newcastle-Ottawa Scale. A random-effects meta-analysis was performed comparing the presence and absence of OFC, cleft type-cleft palate (CP) and cleft lip with or without palate (CL/P)-and cleft laterality-unilateral and bilateral. The certainty of evidence was evaluated using the GRADE approach.

RESULTS

A total of 99 studies were included in the qualitative analysis, and 37 were included in the meta-analysis. Only four studies were classified as low risk of bias. Significant associations were observed between the presence of OFC and tooth agenesis (OR = 19.46; 95%CI = 4.99-75.96), supernumerary teeth (OR = 4.04; 95%CI = 1.26-12.99), developmental defects of enamel (OR = 3.15; 95%CI = 1.28-7.80), microdontia (OR = 15.57; 95%CI = 1.06-228.51), and taurodontism (OR = 1.74; 95%CI = 1.74-2.86). Individuals with CP had a lower frequency of supernumerary teeth (OR = 0.22; 95%CI = 0.08-0.64), peg-shaped tooth (OR = 0.31; 95%CI = 0.12-0.80), and morphological TA (OR = 0.13; 95%CI = 0.04-0.45) than individuals with CL/P. No TA was significantly associated with cleft laterality (p > 0.05). The quality of the evidence was very low in all analyses.

CONCLUSION

Individuals with OFC had a higher frequency of TA than those without OFC. Individuals with CP had a lower frequency of TA than individuals with CL/P. No TA was associated to cleft laterality.

CLINICAL RELEVANCE

Help to identify the treatment needs of individuals affected by OFC, improving the services provided to this population.

A Comparative Study of Oral Health-Related Quality of Life among Cleft Lip and Palate Patients and Their Families during Orthodontic Treatment

(1) Background: It has been recognized that CLP condition may affect oral health-related quality of life (OHRQoL) due to dental anomalies and abnormal craniofacial development. Aim: To assess whether orthodontic treatment affected the levels of OHRQoL in CLP patients and their families. (2) Methods: 226 individuals (111 with cleft and 115 control) and their parents were invited to complete the Oral Health Impact Profile-14 (OHIP-14) and Family Impact Scale (FIS), respectively. The Mann–Whitney test was used for quantitative variables and the Fisher’s exact test for categorical variables. The Spearman Rank Correlation Coefficient was used to correlate the results of the OHIP and FIS questionnaires. (3) Results: No significant difference was found between groups in OHIP-14 but FIS score revealed a significant difference between the two groups evaluated (p < 0.001). Only the social limitation in OHIP score revealed a significant difference (p = 0.001). Regarding FIS score, the most affected dimensions were family activities (p < 0.001), parental emotions (p = 0.001), and family conflict (p = 0.011). (4) Conclusion: Undergoing orthodontic treatment had a similar impact on the overall quality of life in CLP patients and non-cleft patients. Parents of cleft children had a poorer OHRQoL compared to what was perceived by their children and parents of non-cleft children.
