“…[ 27 ] The finding that maxillary laterals were most frequently missing in the arch was consistent in the previous studies that excluded third molars. [ 4 7 9 12 28 29 55 ] Interestingly, in contrast to previously reported, the incidence of missing mandibular laterals is most significant in our study. This study also deduced that agenesis is of higher occurrence in the mandibular arch, contradictory to the findings among the Iranian populations, wherein more missing teeth were found on the maxillary arch.…”

“…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.…”

“…Several studies concluded that hypodontia was the most prevalent dental anomaly,[ 7 9 23 24 ] and this phenomenon is a result of disturbances during the early stages of development. [ 25 ] A survey done by Rakhshan, analyzing the previous reports varying in size from about 200 subjects to about + 100,000, revealed that the prevalence of agenesis in the permanent dentition excluding the third molars ranged between 0.15 and 16.2%.…”

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.

“…En el presente estudio, la frecuencia de supernumerarios estuvo dentro del rango reportado: 4,5%; al igual que el 5% citado en una investigación en Costa Rica en el 2009 (17), o un 3,6% reportado en un estudio en Colombia en el 2014 (2). Dichas frecuencia son altas si se comparan con estudios en España (4), Turquía (22), Australia (23) e India (24) donde la frecuencia de supernumerarios fue inferior al 1%.…”

Dental anomalies can produce alterations in dental shape, number, size, and structure, affecting function and aesthetics. The objective of this study is to determine the frequency and location of teeth number anomalies in healthy Costa Rican children between 6 and 12 years old. An observational and retrospective study was carried out with 157 panoramic radiographs of the patients of the pediatric dentistry and orthodontics clinic of the University of Costa Rica between the years 2015-2017. Hyperdontias and hypodontias were the anomalies observed. Data were analyzed using a Fisher exact test with a significance level of 5% . The results showed that the overall frequency of dental anomalies was 8.3%, 4.5% were hyperdontias and 3.8% hypodontias. Double or multiple hyperdontia and hypodontia were also found. The difference between sex was not significant (p= 0.145). Supernumeraries were more frequent in maxilla and hypodontias in mandible. Mesiodens was the most frequently found supernumerary teeth. Mandibular second premolars were the most commonly missing teeth.

“…4,[7][8][9] The most common dental anomalies in Turkish population is said to be hypodontia. 10 In Turkey, studies showed that the frequency of hypodontia were found between %1.77-%21.6, 11,12 the prevalence of oligodontia were found to be between %0.13-%0.3. 10,13 The most commonly missing teeth were found to be maxillary lateral incisors and followed by mandibular second premolars.…”

Hypodontia is defined as the congenital deficiency of one or more teeth and is one of the most common dental anomalies in humans. Multifactorial etiology can include environmental factors as well, since a combination of environmental and genetic factors might contribute to the occurrence of dental agenesis. Patient with missing teeth; reduced masticatory ability, inarticulate pronunciation may encounter esthetics and periodontal problems. Tooth agenesis definition, etiology, genes that cause tooth agenesis and treatment of tooth agenesis is mentioned in this review. Nowadays, many genes which play role in tooth development reported to be a potential candidate gene in tooth agenesis. Functional changes seen in genes which play role in tooth agenesis are mentioned that there may be a relationship with the development of cancer and tooth agenesis may be a significant marker for cancer.
