Evaluación del canino maxilar permanente en niños entre 8 y 11 años en radiografía panorámica

The permanent maxillary canine (PMC) is the second most frequently impacted tooth due to its long intraosseous descent and eruption chronology. The objective of this study was to evaluate the degree of dental development and position of the PMC between the ages of 8 and 11 years 11 months in order to suggest an optimal chronological age for their early evaluation in panoramic radiography. A retrospective study was carried out, where 239 panoramic radiographs of children aged 8 to 11 years were analyzed. They were grouped according to age, gender and apical area; Then, the degree of dental development and position of the left PMC apex were analyzed. The results show that there are no significant differences in the position of the PMC with respect to chronological age. Furthermore, between eight years six months and nine years six months, 61% of the canines had more than half of the root formed. In conclusion, the early evaluation with panoramic radiography of the PMC is suggested from eight years six months to nine years six months, to alert the clinician in cases where the eruptive path is deviated.
