“…Previous reports showed associations between microdontia and peg-shaped teeth with IMC [10, 12]. This study coincided with the association between microdontia and IMC, but barrel-shaped rather than peg-shaped incisors were the second association.…”

“…The prevalence of IMC was also associated with the presence of other impacted teeth, which agrees with data from a Chinese population [10]. Associations between anomalies can often be explained genetically [21, 22] especially when the impacted tooth is far from the IMC in question.…”

“…If third molars are excluded, the maxillary canines are the most common teeth to experience impaction [3, 6–8], and patients with impacted maxillary canines (IMC) often exhibit other associated dental anomalies [9, 10]. The frequent association of these anomalies has led some researchers to suggest their use as markers to indicate the need for further clinical and/or X-ray analyses to create early diagnosis [11].…”

Objective. We quantified the prevalence of impacted maxillary canines (IMC) and their association with other dental anomalies (DAs). Materials and Methods. A retrospective study was done with 860 patients 12 to 39 years of age. The prevalence of IMC was calculated and compared by sex. The sample was divided into a control group and an impaction group, and the prevalence was calculated in both for a series of anomalies: agenesis, supernumerary teeth, shape anomalies of the upper laterals (microdontia, peg and barrel shape, and talon cusp), fusion, gemination, other impacted teeth, transposition, and amelogenesis imperfecta. The prevalence values for both groups were compared (Pearson's χ2 test, p ≤ 0.05). Results. IMC were present in 6.04% of the sample with no difference by sex (p = 0.540). Other DAs occurred in 51.92% of the IMC group and in 20.17% of the controls (p < 0.05). Significant associations (p < 0.05) were identified between IMC and four other DAs: microdontia, barrel shape, other impacted teeth, and transposition. The prevalence of all anomalies was lower in the control group. Conclusion. IMC were seen in 6.04% of patients. Patients with this condition also had a higher prevalence of other DAs. These other anomalies should be used as risk indicators for early diagnosis.

Aim:The aim of the present study was to investigate the association between unerupted permanent incisors and dental anomalies among children and adolescents. Methods:The clinical records of patients between January 2005 and December 2014 were retrieved to identify those with unerupted permanent incisors. A retrospective audit on the presence or absence of any dental anomalies was done from all available records of the included patients. Results:A total of 266 patients with 320 unerupted permanent incisors were identified from the 15 987 patients in the study. Among the unerupted permanent incisors, 222 (69.4%) were associated with dental anomalies, which was significantly higher than those showing an absence of dental anomalies (N = 98, 30.6%, P < 0.001). For the unerupted maxillary central incisors, a significantly higher proportion was associated with supernumerary teeth (P < 0.001). For the unerupted maxillary lateral incisors, a significantly higher proportion was associated with the ectopic eruption of permanent canines when compared with other dental anomalies (P < 0.001). The presence of the ectopic eruption of permanent canine, double teeth, and hyperdontia was significantly higher among male patients with unerupted permanent incisors. Conclusions:Unerupted permanent incisors were associated with supernumerary teeth and ectopic eruption of permanent canines. Specifically, a higher proportion of unerupted maxillary central incisors was associated with the presence of supernumerary teeth, whereas a higher percentage of unerupted maxillary lateral incisors was associated with the ectopic eruption of permanent canines. K E Y W O R D S dental anomalies, ectopic eruption, permanent canines, supernumerary teeth, unerupted permanent incisors 1 | INTRODUC TI ON According to the updated clinical guidelines of Royal College of Surgeons of England, an observation or intervention is needed for unerupted permanent maxillary central incisors when there is aberration from the standard sequence of eruption, or the contralateral teeth have erupted >6 months ahead of the unerupted incisors, or both central incisors remain unerupted and the lower incisors erupted >1 year prior. 1 The incidence of unerupted maxillary incisors in 5-12-year-old children has been reported to be 0.13%, 2 while the How to cite this article: Tan C, Ekambaram M, Lee GHM, Yiu CKY.

Background The study evaluates the position and displacement tendency of unerupted maxillary canines in orthodontic patients with non-syndromic craniofacial disorders (CD) compared to a control (C) group. Methods Canine position and displacement tendency were evaluated using panoramic radiographs (PAN) examined with parameters such as sector classification (sectors 1–5) and inclination angles (α and β). The displacement tendency was defined as the positioning of the tip in sectors 1 or 2, as well as its combination with increased angles (α > 30° and β > 39°). In addition, the correlation of the tooth position and agenesis, cleft side, and sex was assessed. Results A total of 116 pre-treatment PAN, divided into the CD group (n = 50; mean age 8.32 ± 2.27 years) and the C group (n = 66; mean age 10.80 ± 2.82 years), were evaluated in this study. The sector classification showed no displacement tendency in both groups. Inclination angles α/β showed a statistically significant higher displacement tendency (p = 0.01) of the CD group (n = 5) on the right side, compared to healthy subjects (n = 1). Male CD patients had a statistically significant higher displacement tendency on the right side (p = 0.03). A statistically significant correlation between cleft and non-cleft-side (p = 0.03) was found. Conclusion Patients with CD showed a statistically significant higher displacement tendency of the maxillary canine affected by the cleft side. The inclination angle was found to be the better predictor compared to the sector classification which should be considered in the orthodontic treatment planning.
