The study aims to investigate the impact of missing maxillary lateral incisors on canine impaction in the human oral cavity. Specifically, it seeks to validate or refute the “Guidance Theory,” which suggests that maxillary lateral incisors play a pivotal role in guiding the proper eruption of canines. After examining 1021 panoramic radiographs, we identified individuals who met the inclusion criteria and were devoid of any syndromic or hereditary anomalies affecting root formation. Our findings corroborate the “Guidance Theory.” This conclusion is based on the observation that 6 (5.41%) out of the 111 panoramic radiographs exhibited both dental anomalies missing maxillary lateral incisors and canine impaction. To deepen our understanding, we also conducted measurements concerning the angulation and depth of impacted canines. These additional analyses further elucidate the interconnected impact of the two associated dental anomalies.
