Abstract: We encountered a case of impacted maxillary molars in a 14-year-old girl. The mandibular
right second permanent molar was over-erupted. It was a very rare and complicated case requiring
prolonged and costly orthodontic treatment. School children undergo a dental examination every year at
school. A school dentist should have previously suspected a delay in the eruption of the maxillary first
molar when the present patient was 8 years old during school dental examination. However, the patient
visited a dental clinic at the age of 14, indicating that post-examination care was not given. School dental
examination had been conducted for a total period of 5 years without any post-examination care. If the
patient had been referred to a family dentist or an orthodontist promptly, less complicated treatment
would have been possible. This was a typical case that showed the importance of post-examination care
after conducting a school dental examination. It is the social responsibility of dentists to not only treat
patients at dental clinics but also contribute to the promotion of school children s health through schoolbased examinations. School dentists should therefore be strongly requested to conduct oral examinations
carefully based on a sense of duty.
