Evaluation of dental anomalies in permanent dentition as a part of cleft spectrum -A radiographic study

Prevalence of dental anomalies in deciduous dentition and its association with succedaneous dentition: A cross-sectional study of 4180 South Indian children.

The objective of this study was to estimate the prevalence of dental anomalies in primary dentition of Indian population. This cross-sectional study was conducted on 4180 children in the age of 2-6 years. Anomalies were classified based on Kreiborg criteria. The term "double tooth" was used to avoid misinterpretation between gemination. and fusion. Patients having radiographs were also examined for associated dental anomalies in permanent dentition. The occurrence and gender prevalence were evaluated using descriptive statistics. About 95. (2.27%) children exhibited at least one dental anomaly. Thirty.seven children showed 51 missing teeth. (0.88%), mostly in lower right incisors with a statistically significant difference between arches. (P = 0.0056) Nine children. (0.21%) had supernumerary teeth commonly in the right maxilla. Two cases of oligodontia. (0.04%) and talon cusps. (0.04%) and one case of triple tooth. (0.02%) were observed. Forty children. (0.95%) had 43 double teeth mostly in the right mandible with a statistically significant difference between the arches. (P = 0.0105). No significant difference was observed based on gender and arch, but they were statistically significant between the right and left sides. (P = 0.018). Among the children with radiographs available, 45% showed anomalies in the succedaneous dentition. The prevalence rates of children with double tooth, hypodontia, and hyperdontia in our study are 0.95%, 0.88%, and 0.21%, respectively. The overall prevalence rate of anomalies among boys was higher than girls.

Prevalence of Dental Anomalies in Permanent Dentition of Brazilian Individuals with Down Syndrome.

Objective:The aim of this study was to evaluate the incidence of dental anomalies in the permanent dentition of individuals with Down Syndrome (DS) to increase the knowledge on the dental issues in this syndrome. Method:One hundred and five panoramic X-rays of patients with DS (61 males and 44 females), aged 7 to 42 years were used. The data were statistically analyzed using bivariate analyses test (p <0.05). Results:Dental anomalies were observed in 50.47% of the sample. More than one anomaly was observed in 9.52% of the individuals. The most frequent dental anomalies were hypodontia and microdontia (16.19%), followed by retained tooth (10.47%), taurodontism (9.52%), supernumerary teeth (5.71%), macrodontia (2.85%) and root dilaceration (0.95%). There was no statistically significant difference between genders for any of the anomalies. Conclusion: A high prevalence of dental anomalies was observed in individuals with DS. The results of the present study reinforce the importance of good dental care, offering a greater basis for professionals who provide dental service to these patients.

Treatment of Dental Anomalies in Children with Complete Unilateral Cleft Lip and Palate at Sickkids Hospital, Toronto

To quantify dental anomalies in permanent dentition associated with complete unilateral cleft lip and palate and to survey treatment modalities used to address these problems. Retrospective study of 116 children with complete unilateral cleft lip and palate treated at SickKids since birth. Presence and morphology of lateral incisors and second premolars were determined. Orthodontic, surgical, and/or prosthetic procedures were analyzed. The cleft-side lateral incisor was absent in 93.1% of finished cases. The lateral incisor mesial to the cleft was present in 4.3%, absent due to agenesis in 75.9%, and extracted in 19.8% of cases. The lateral distal to the cleft was present in 2.6%, absent due to agenesis in 33.6%, and extracted in 63.8% of cases. Of 105 lateral incisors, only one had normal morphology. Noncleft-side lateral incisors were absent in 16% of finished cases. Absence was due to agenesis in 12.1% of cases and extraction in 4.3%. When the lateral incisor was missing, closure of the dental space occurred by orthodontic tooth movement after alveolar bone grafting (45%); surgical closure with simultaneous alveolar bone grafting (35%); prosthetic closure (17%); and 3% were failures. Agenesis of premolars occurred in 12.1% of cleft-side and 10.3% of noncleft-side maxillary second premolars. The cleft-side lateral incisor is rarely present at the conclusion of orthodontic and surgical treatment of complete unilateral cleft lip and palate. Often absent due to agenesis, when present it is typically abnormal in size and bone support and is commonly extracted in favor of canine substitution.

Bilateral fusion of permanent canine and lateral incisor

Fusion is described as the union of two or more tooth buds. It is characterized by a reduced number of teeth , when fused tooth is counted as one . The prevalence of fused teeth in primary dentition is below 1% and even more less in permanent dentition. The occurrence of fusion in primary dentition may be followed by dental anomalies in permanent dentition. This case report presents a case of bilateral fusion of lateral incisor and canine in primary dentition which was followed by similar fusion in permanent dentition. The aim of this report is to highlight the rarity of such condition by virtue of the number of such cases reported in literature and to evaluate their pulpal morphologies to understand the type of fusion and presence of any other associated pathologies.
