This case presents a rare example of self-correction of a deeply impacted mandibular second premolar (LR5) in a medically fit 14-year-old male patient, referred in 2017 regarding a retained deciduous lower right second molar (LRe). CBCT imaging highlighted that the origin of the ID canal was in direct contact with the inferior buccal aspect of the LR5 root apex. The decision was made to monitor the patient in 2 years. In the meantime, the dentist extracted the retained LRe as it was seen to be erupting on routine bitewing imaging. At his review appointment, the LR5 had spontaneously erupted.
CPD/Clinical Relevance: To highlight the potential benefit of monitoring eruption in the event that high-risk surgery is the alternative option and involving the patient in the decision making.
Article
This case presents a rare example of self-correction of a deep and disto-angularly positioned impacted mandibular second premolar. A 14-year-old male patient was referred by his dentist to the Oral and Maxillofacial department in Prince Charles Hospital, South Wales, regarding a retained deciduous lower right second molar (LRe) and an impacted lower right second premolar (LR5). He was medically fit and well with no known allergies. He had good oral hygiene and was a regular attender at his dentist, with no history of previous trauma or orthodontic treatment.
He attended his referral appointment in 2017. He presented with a Class I malocclusion on a skeletal Class I base with increased lower anterior facial height. He had both an average Frankfort mandibular plane angle and nasolabial angle, with no asymmetry. His lips were competent at rest and 90% of his upper incisal surfaces showed on smiling. There were no abnormalities detected with his temporomandibular joint.
