“…However, the literature has conflicting results (5,6,8,19), perhaps explained by the different populations studied. Regarding the tooth size, microdontia was the most frequent anomaly, and the upper lateral incisors were the most affected teeth, in line with the findings of Guttal et al (21).…”

“…Other authors also reported the absence of these teeth (6)(7)(8)(22)(23)(24). Congenital absence of teeth in modern man is not surprising from an evolutionary perspective and there are various genes involved in this change.…”

“…In Australian orthodontic patients, the most missing permanent teeth were the second lower premolars (27), as well as in Swedish (28) and Brazilian children (8). Indian (29), Turkish (13), and Japanese (30) populations revealed upper lateral incisors as the most missing teeth.…”

“…Patients with tooth agenesis have an increased risk of infraocclusion of deciduous molars and gemination or fusion of deciduous incisors (8). In addition, dental anomalies have been associated with Class II, division 2 malocclusion (9), thus indicating a strong genetic influence in the development of this type of malocclusion (10).…”

Developmental dental anomalies have been associated with different malocclusions in various populations. This study verified this association in Brazilian non-syndromic orthodontic patients. The prevalence of dental anomalies was evaluated by examining 2,052 pretreatment records of orthodontic patients. Panoramic radiographs, study designs, intraoral photographs and medical history were collected in order to identify hypodontia, hyperdontia, microdontia, macrodontia, taurodontism, transposition, impaction, and ectopia. Epidemiological data and classification of malocclusion were also obtained. Data were analyzed using chi-square and Fisherʼs exact test (P < 0.05), and the prevalence ratio was obtained from cases that had a significant association between anomaly and malocclusion. The results showed that 27.4% of the patients evaluated had some dental anomaly, and most of them were white women aged 11-20 years. Ectopia, microdontia, impaction, and hypodontia were more prevalent in patients with Class I malocclusion. Macrodontia was the only anomaly associated with Class II division 1. Impaction was associated with Class III malocclusion, at a 1.84-times higher prevalence. In conclusion, impaction was correlated with Class I malocclusion; macrodontia showed association with Class II division 1; and impaction and ectopia were associated with Class III malocclusion in Brazilian orthodontic patients.

“…Dentre as particularidades odontológicas mais comuns encontram-se as alterações dentárias presentes tanto na dentadura decídua como na permanente com uma prevalência de 36% a 53% nesse grupo (LARSON et al, 1998;MONTANDON;DUARTE;FURTADO, 2001;VANZIN;YAMAZAKI, 2002;HELIOVAARA;RAUTIO, 2004), ocorrendo com maior freqüência em indivíduos com fissura completa de lábio e palato. A agenesia dentária é a alteração de maior ocorrência na dentadura permanente, com prevalência variando de 16% a 46% em indivíduos com fissura em comparação com uma prevalência entre 1,5% e 10% na população geral, com exclusão das agenesias de 3 os molares (RANTA; STEGARS; RINTALA, 1983;HELLQUIST;JAKOBSON, 1998;VASTARDIS, 2000;MONTANDON;DUARTE;FURTADO, 2001;HELIOVAARA;RAUTIO, 2004;VIEIRA et al, 2007b;KÜCHLER et al, 2008).…”

Purpose Third molar agenesis (TMA) is the most common craniofacial anomaly and has been associated with craniofacial patterns in different populations. Therefore, the aim of this retrospective cross-sectional study was to assess a possible association between craniofacial patterns and TMA in German orthodontic patients. Methods Patients undergoing orthodontic treatment with dental records including anamnesis, pretreatment lateral cephalograms and orthopantomograms were evaluated. Cephalometric analyses were conducted digitally and lines, angles and proportions were measured to investigate craniofacial morphology. Skeletal classes were determined by the individualised Wits appraisal and ANB angle. The TMA was identified with the help of orthopantomograms. Patients showing agenesis of at least one third molar were included in the TMA group. Statistical analysis was performed to assess the association between TMA and craniofacial patterns (α of p ≤ 0.05). Results A total of 148 patients were included, 40 (27.0%) presented at least one missing tooth (TMA group) and 108 (73.0%) showed full dentition (control group). Skeletal class determined by the individualised Wits appraisal revealed statistical significance between the TMA and control groups (p = 0.022), in which TMA patients were 11 times more likely to present with an individualised skeletal class III (odds ratio 11.3, 95% confidence interval 1.7–139.5). Skeletal cephalometric analysis revealed no statistical differences between TMA and control groups for any further angular, linear and proportional parameters. Conclusion Third molar agenesis was associated with skeletal class III determined by the individualised Wits appraisal.
