ABSTRACT Objectives To compare the normal eruption pattern and angulation in impacted maxillary canines using panoramic radiographs to predict maxillary canine impaction. Materials and Methods Patients aged 6 to 15 years were classified into the normal eruption group (n = 229) and the impaction group (n = 191). At least two panoramic radiographs were taken in the normal eruption group during the eruption process of the maxillary canine. The growth pattern of the maxillary canine was analyzed using an XY coordinate system, with the tip of the maxillary lateral incisor as the origin and the tooth's long axis as the Y-axis and measurement of the relative position of the crown tip and angulation of the maxillary canine. Results The crown tips of normally erupted maxillary canines were intensively distributed along the distal surface of the maxillary lateral incisor, while those of impacted canines were widely distributed. The angulations of the normally erupted canines increased as eruption increased along the lateral incisor and then decreased at the cervical point of the lateral incisor. The angulations of the impacted canines were scattered, with no uniform pattern. Conclusions While using the normal eruption path of the maxillary canine and the pattern of change in angulation based on the distal surface of the maxillary lateral incisor, early intervention or regular follow-up is needed to prevent maxillary canine impaction.

Objective: To investigate the probability and pattern of maxillary canine impaction in relation to anomalous adjacent lateral incisors. Subjects and Method: A total 66 patients (M=24, F=42) in the age range of 12 to 18 years who had at least one impacted maxillary canine were included for the study. The maxillary lateral incisor anomalies and nature of canine impactions were diagnosed from the radiographs and study models. Maxillary lateral incisors were classified as normal, peg shaped, impacted and congenitally missing. The maxillary canine impactions were classified as buccal and palatal impaction. Each affected maxillary side was considered separately. This resulted total 88 cases for which the probabilities of different canine positions adjacent to the different categories of lateral incisor anomalies were evaluated statistically. Results:The occurrence of palatal canine impaction was almost1.6 times more than the buccal canine impaction. Total 11.76% of the bucally impacted canines and 38.89% of the palatally impacted canines were associated with anomalous lateral incisors. There was no positive association between anomalous lateral incisors and maxillary canines. In relation to anomalous lateral incisor, the probability of palatal canine impaction was more than the buccal canine impaction. Conclusions: There was no positive association between lateral incisor anomalies and maxillary canine impaction. However, there was a high probability of palatal canine impaction when adjacent lateral incisors were anomalous.

Objective. The purpose of this study was to investigate the interrelationships between displacement of maxillary canine and tooth agenesis in age from 10 to 19 years. Study design. The panoramic radiographs of 128 subjects with displacement of maxillary canine and 600 subjects without displacement of maxillary canine were examined. The panoramic radiographs taken between 2003 and 2013 were used for diagnosis other related dental anomalies, including permanent tooth agenesis and small maxillary lateral incisor. Results. Patients with maxillary canine displacement had a significantly higher prevalence rate of permanent tooth agenesis excluding of third molars (p < 0.05). Significant increase in occurrence of tooth agenesis of maxillary lateral incisor (p < 0.05), maxillary second premolar (p < 0.05) and small maxillary lateral incisor (p < 0.05). In contrast, the mandibular second premolar did not show any significant difference (p > 0.05). Conclusion. This study indicates that there is positive relationship between displacement of maxillary canine, small maxillary lateral incisor and permanent tooth agenesis. Especially, maxillary lateral incisor and maxillary second premolar have strong association with maxillary canine displacement. Consequently, permanent tooth agenesis and small maxillary lateral incisor can be a predictor of maxillary canine displacement.

Uncommon Tumor

Adenomatoid odontogenic tumor (AOT), a benign (hamartomatous) lesion of odontogenic origin, is an uncommon tumor which affects mainly females in the second decade. This lesion is most commonly associated with an impacted maxillary canine. This paper reported a case of AOT, in a 16-year-old female, associated with an impacted maxillary left lateral incisor. The evolution of this tumor was followed over 36 months and 24 months after excision.

Criteria For Selection

Background/Aim. Many authors find that impacted maxillary canines is associated with missing and peg-shaped lateral incisor. The aim of this study was to examine the prevalence of peg-shaped and missing lateral incisor in subjects with impacted maxillary canines, and compare the size of maxillary lateral incisor on the side with palatally impacted canines and on the opposite side of the jaw where there is no impaction. Methods. The study included 64 patients with 80 impacted maxillary canines (23 males and 41 females, mean age 16.3). For each maxillary unerupted canine, precisely correct localization and classification into groups was done. We analyzed the morphology of the lateral incisor (normal, atypical) and frequency of missing of lateral maxillary incisors with canine impaction. Then, from the mentioned examinees sample with the maxillary canine teeth, a subgroup was formed. The criteria for selection were those with unilateral palatally impacted canines (33 subjects, 22 females and 11 males, mean age 17.8 years). The linear variables of the maxillary lateral incisor were measured by using digital measurements tools. The t-test was used to test the differences between the groups. Results. Normal morphology of the lateral incisors was found in 72% of the subjects with the impacted canines, 11.2% of the subjects had the peg-shaped lateral incisors, 6% had a bilateral and 4% had unilateral deficiency of lateral incisors. In the subgroup of the patients with unilateral palatal impaction, the middle value of the length of the lateral incisors was 1.9 mm shorter and the middle value of the width of the lateral incisors was smaller by 0.9 mm when comparing to the control group. Conclusion. The frequency of the deficiency of lateral incisors was statistically significantly higher in the group with palatal canine impaction. The maxillary lateral incisors on the side with palatally impacted canines were smaller than those on the side where there was no impaction.

ABSTRACT The relationship between maxillary lateral incisor anodontia and the palatal displacement of unerupted maxillary canines cannot be considered as a multiple tooth abnormality with defined genetic etiology in order to be regarded as a “syndrome”. Neither were the involved genes identified and located in the human genome, nor was it presumed on which chromosome the responsible gene would be located. The palatal maxillary canine displacement in cases of partial anodontia of the maxillary lateral incisor is potentially associated with environmental changes caused by its absence in its place of formation and eruption, which would characterize an epigenetic etiology. The lack of the maxillary lateral incisor in the canine region means removing one of the reference guides for the eruptive trajectory of the maxillary canine, which would therefore, not erupt and /or impact on the palate. Consequently, and in sequence, it would lead to malocclusion, maxillary atresia, transposition, prolonged retention of the deciduous canine and resorption in the neighboring teeth. Thus, we can say that we are dealing with a set of anomalies and multiple sequential changes known as sequential development anomalies or, simply, sequence. Once the epigenetics and sequential condition is accepted for this clinical picture, it could be called “Maxillary Lateral Incisor Partial Anodontia Sequence.”

Two groups of subjects who demonstrated unilateral maxillary canine impaction were examined, a Caucasian group and an Oriental group. It was found that there are significant differences between the groups for sex of patients seeking treatment, site of impaction (buccal/palatal), and arch form. The Oriental group was significantly more crowded in the canine area than the Caucasian group. In almost all cases the dimensions of the lateral incisor on the side of impaction were smaller than the non-impacted side, although five subjects from the Caucasian female sub-group did not conform to this pattern, and for the Oriental male sub-group the mesiodistal crown width was larger on the impacted side.
