“…A possible explanation for this finding lies in the fact that dental agenesis and DEI may have the same genetic background. 17 The findings of this study cannot be generalized to all ethnic and age groups nor can it be generalized to nonorthodontic patients. Future studies are warranted to identify the prevalence of dental anomalies in larger samples of orthodontic population presenting from different race, age group, and severity of malocclusion and explore the causes of occurrences.…”

“…10 Dental agenesis is frequently associated with various types of dental anomalies such as microdontia, delayed dental development and isolated tooth ectopias. 16,17 The objectives of this retrospective study were to determine the prevalence of permanent tooth anomalies present in patients attending the orthodontic clinic at the State University of New York at Buffalo and the types of malocclusions associated with them.…”

Objective: To determine the prevalence of permanent tooth anomalies in patients attending the graduate orthodontic clinic at the State University of New York at Buffalo. Materials and methods:Charts of 496 subjects (310 females and 186 males) met the inclusion criteria for this study. The mean ages were 16 years and 3 months for the combined gender sample that received orthodontic treatment in the graduate orthodontic clinic between 2007 and 2010. Full pretreatment records (intraoral photographs, digital study models, lateral cephalograms and panoramic radiographs) were used for the assessment. Charts were examined for these anomalies: agenesis, supernumerary, impaction and delayed tooth eruption. Subjects were categorized by gender and ethnicity. The percentages of the anomalies were assessed according to type of malocclusion, gender, race, location, tooth class and region in the dental arches.Results: Sixty-four subjects (12.9%) had at least one occurrence of delayed eruption and impaction (DEI), followed by 47 subjects (9.5%) who had at least one occurrence of agenesis, and seven (1.4%) had a supernumerary condition. Approximately 80% of the subjects had no dental anomalies. The presence of more than one anomaly was observed in 61 subjects. Twelve subjects (2.4%) had both agenesis and DEI. Agenesis tended to be more common in class II malocclusions (p = 0.012). Conclusion:The prevalence of permanent tooth anomalies was (20.4%). The percentage occurrence of DEI was the highest (12.9%) followed by dental agenesis (9.5%) and supernumerary teeth (1.4%) in the orthodontic patients at the State University of New York at Buffalo.

“…Later on, the patient develops malignant intestinal tumors that are hard to treat and have a more doubtful prognosis. A dentist on the alert may suspect a new case of Gardner syndrome by observing atypical osteoma-like lesions in a young patient and referring him/her to medical evaluation 10 . Palatally impacted maxillary canines seem to have a genetic etiology 6,11 , and are frequently associated with other changes, such as microdontia of maxillary lateral incisors [11][12] , delayed tooth eruption 13 and fusion of the clinoid processes of the sella turcica 14 .…”

Aim: To investigate the association between palatally impacted maxillary canines (PIC) and idiopathic osteosclerosis. Methods: A sample of 54 subjects (28 females and 26 males, mean age of 12.98±1.59 years) with PIC was selected from the records of 1,650 orthodontic patients treated at the Discipline of Orthodontics clinics at the Dental School of the Pontifical Catholic University of Paraná (PUCPR), in Curitiba, PR, Brazil. A control group of 54 subjects with normally erupted canines was also selected from the same files (mean age of 12.93±1.58 years). Panoramic, lateral skull, postero-anterior skull, periapical and occlusal radiographs, as well as stone casts of the patients were examined. The Kolmogorov-Smirnov test revealed a normal distribution of gender and age in the groups. The results were analyzed with the Chi-square test (α=0.05). Results: There were no statistically significant differences (p>0.05) between the groups. Four patients from each group had idiopathic osteosclerosis (7.41%), a rate that falls in the prevalence range reported in the literature. Conclusions: No correlation was observed between palatally impacted maxillary canines and idiopathic osteosclerosis.

“…Yaqoob et al (2011) stated that isolated bilateral absence of maxillary lateral incisors is associated with reduced mesiodistal tooth widths of both maxillary and mandibular anterior segments. Some authors stated that permanent tooth agenesis, maxillary lateral incisor microdontia, palatally displaced canines, and distoangulation of mandibular second premolars are frequently associated with maxillary lateral incisor agenesis, providing additional evidence of genetic interrelationship as cause for these dental anomalies (Garib et al, 2010). For others, the factors involved in third molar agenesis and that of other teeth are probably the same (Baum & Cohen, 1971).…”
