“…In other part of the world, prevalence of impaction has been reported at 3.74% in Indian population 37 and 8.4% in Norwegian population. 38 In similar studies done on non-orthodontic population, prevalence has been found to be 8.3% and 9.9% by Ezoddini et al 4 & Thongudomporn and Freer 39 respectively.…”

Background: Dental anomalies are significant deviation in the anatomy, morphology, number, dimension and eruption pattern of teeth. Their effects can range from being negligible to having extreme consequences on the stomatognathic system. Objective: The aim of this study was to evaluate the prevalence, gender and arch distribution of selected dental anomalies in the population of Najran city of Saudi Arabia. It also aims to compare the dental anomalies in Najran population with the other population of Saudi Arabia and other parts of world. Material and Methods: The study sample included 572 patients (196 male and 376 females) between the ages of 8-34 years, who visited the orthodontic department in dental college clinic of Najran university and Najran University hospital in the year 2019. The data was collected through clinical examination, dental cast evaluation and digital panoramic radiographic assessment. Seven dental anomalies including hypodontia, impaction (excluding third molars), supernumerary teeth, peg shaped laterals, hypercementosis, taurodontism and transposition were evaluated in the study. Results: The most prevalent dental anomaly was found to be transposition (29.4%) followed by impaction (23.4%), hypodontia (21.2%), peg shaped lateral incisor (8.4%) and hypercementosis (3.1%). Only hypodontia showed statistically significant difference between males and females. Taurodontism and supernumerary teeth were the least prevalent anomaly at 1.4%. Conclusion: Results of the study provide insights into the prevalence of dental anomalies in Najran population of Saudi Arabia. This data can be useful both epidemiologically and clinically to combat the problem of dental anomaly.

“…Its prevalence varies between countries and tribes. For example congenitally missing teeth is the most prevalent dental anomaly found in Indians [ 1 , 2 ], Saudi Arabians [ 3 ], Turkish [ 4 ] and Norwegian children [ 5 ]. In Nigeria however, enamel hypoplasia is the most common dental anomaly in children while hypodontia is a rare clinical feature [ 6 , 7 ].…”

Prevalence of developmental dental hard-tissue anomalies and association with caries and oral hygiene status of children in Southwestern, Nigeria

BackgroundDevelopmental dental hard tissue anomalies are often associated with oral health problems. This study determined the clinical prevalence of developmental dental hard tissue anomalies in the permanent dentition of children resident in southwestern Nigeria and its association with dental caries and poor oral hygiene status.MethodsThis was a cross-sectional study recruiting 1565 school children, 12 to 15 year old attending schools in Ibadan, Oyo State and Ile-Ife, Osun State. All eligible study participants had oral examinations conducted to determine presence of developmental hard dental tissue anomalies, caries and oral hygiene status. The prevalence of developmental dental hard tissue anomalies was determined. Logistic Poisson regression was used to determine the association of between developmental dental hard tissue anomalies, caries and oral hygiene status.ResultsOnly 65 (4.2 %) children had clinically diagnosed developmental dental hard tissue anomalies. The most prevalent anomaly was enamel hypoplasia (2.2 %). More females (p = 0.003) and more children with middle socioeconomic class (p = 0.001) had enamel hypoplasia. The probability of having poor oral hygiene was significantly increased for children with developmental dental anomalies (APR: 0.07; 95 % CI: 0.03 – 0.12; p = 0.002). The probability of having caries was insignificantly increased for children with developmental dental hard tissue anomalies (APR: 0.005; 95 % CI: −0.03 – 0.04; p = 0.08).ConclusionThe most prevalence clinically detectable developmental dental hard tissue anomalies for the study population was enamel hypoplasia. The presence of developmental dental hard tissue anomalies significantly increased the chances of having poor oral hygiene but not caries. Further studies are required to understand if poor oral hygiene is associated with dental caries in children with developmental dental hard tissue anomalies.

“…In studies conducted within the past 6 years, the prevalence ranged from 4.74 to 45.1%. [ 4 7 8 9 10 11 12 13 ] These variations are most likely due to the sampling technique, subject's inclusion criteria, and the study design. Unlike other researches which assessed the radiographs and dental records alone, this study was supplemented by the subjects’ study cast.…”

“…Our findings demonstrated 28.4% subjects with at least a single anomaly, at a very close range with the Norway and Iran population, at 28.2 and 29%, respectively. [ 10 11 ] However, both studies included those in mixed dentition. Uslu et al .…”

OBJECTIVE:This study was carried to study the prevalence of dental anomalies and treatment modalities/planning among the orthodontic patients.MATERIALS AND METHODS:A total of 370 orthodontic records including their pre-treatment orthopantomographs (OPG) and study models of orthodontic patients in permanent dentition who attended dental clinic were assessed for impaction, hypodontia, supernumerary, supraocclusion, infraocclusion, and any other anomalies excluding the third molars. The association of anomalies with gender status and racial status was analyzed using Pearson's Chi-square test. A P value of <0.05 is considered as significant. The confidence interval at 95% (CI) was set.RESULTS:Among the 370 subjects, 105 (28.4%) presented with at least one anomaly. Eighty-five (23%) demonstrated a single anomaly and 20 (5.4%) with more than one anomaly. The most prevalent anomaly was impaction (14.32%), followed by hypodontia (7.03%). The less common anomalies were microdontia (1.08%), dilacerations (0.27%), and generalised enamel hypoplasia (0.27%). Maxillary right lateral incisors and canines were the most common affected teeth and these are located on the maxillary right quadrant. It was evident that dental anomalies were statistically dependant on race (P = 0.025), but independent of gender. The most common treatment planned for these patients was fixed appliance.CONCLUSIONS:Impaction was predominant among 28.4% subjects observed with anomaly and most patients with anomaly are treated with fixed appliances (49%).CLINICAL RELEVANCE:These anomalies play a great role in occlusion and alignment in treatment planning and relapse for orthodontic treatment.
