Abstract
A 10-year-1-month-old girl presented an unerupted maxillary primary right second molar and a congenitally missing permanent 2nd premolar case. Long term oral management and continued observation and treatment were done.1.X-ray findings and a thorough oral examination during the initial visit showed an impacted primary maxillary right second molar. At this point, the succeeding permanent 2nd premolar was not yet visible.2.After one month from the initial visit, bone fenestration of the maxillary impacted molar was done to promote natural eruption. Observation was done for 3−6 months.3.3 months after bone fenestration, there was a tendency of eruption but no marked change. Thus, a decision to do bone fenestration again was done to move the tooth orthodontically.4.3 months after orthodontic treatment, the right permanent maxillary second premolar became visible by x-ray examination.5.The patient came back at 17 years and 5 months of age after regular recalls and presented a right permanent maxillary second premolar in the first stage of eruption. At age 18 years 10 months, she presented a premolar that almost reached the occlusal plane.
