The various causes include local, systemic, and genetic factors. To prevent complications, early prediction and age-appropriate intervention are crucial for initiating timely interceptive orthodontic treatment, thereby reducing treatment duration and cost.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aim:<\/jats:title>\n                    <jats:p>To validate the modified Erickson\u2019s and Kuroll\u2019s method in predicting the prevalence of canine impaction in children aged 14\u201318 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>Children visiting the outpatient department in the department of pediatric dentistry from October 2024 to December 2024 with orthopantomograms (OPGs) available during their mixed dentition stage of age 7\u201313 years were screened.

Based on the inclusion criteria, 90 OPGs of children were included, traced, and analyzed by a single operator using Modified Erickson and Kuroll\u2019s sectorial method.
