| Statement of Problem: There are different views about the optimal time for detection and prevention of maxillary canine impaction. With respect to the large individual variation in the timing of eruption of the teeth, it seems reasonable not to consider chronological age as a valid criterion in this regard.Purpose: The aim of this study was to compare dental and chronological ages in the diagnosis of potential maxillary canine impaction.Methods and Material: This analytical cross-sectional study was done on 2704 students aged 10-11 year in Mashhad. In the first group (1232 children), all of the children whose maxillary canine bulges were not palpable were suspected with impaction and referred for radiographic examination. In the second group (1472 children), the children whose canine bulges were not palpable were referred for radiographic examination if only the first premolars had erupted or were erupting. The condition of the lateral incisor teeth was inspected in children suspected with impaction. The data were analyzed by comparing the proportion of success and Fisher’s exact test.Results: From the children examined in the first group, 9.3% and from those examined in the second group, 5.5% were suspected with impaction in the clinical examination. The application of dental age reduced the number of referrals for radiographic examination significantly ( p <0.05). There was an association between palatal position of the maxillary canines and anomalous lateral incisors ( p <0.05).Conclusion: Consideration of chronological age in early diagnosis of maxillary canine impaction may result in unnecessary radiographic examination. The number of referrals for radiographic examination will be significantly reduced when the developmental stage of dentition is considered.Key words: Impaction, Maxillary canine tooth, Chronological age, Dental age | ||
