Patient Scenarios

Patient Scenario 1

An eight-year-old male patient, David, arrives for a new patient appointment accompanied by his mother. Review of the patient’s dental and medical histories are noncontributory. Further discussion with David’s mother indicates that the family lives outside the city limits and drinks non-fluoridated well water. It has been a year or two since her son has seen a dentist due to a new employment opportunity and subsequent family relocation. David has had several new permanent teeth erupt. The mother reports that she had several missing permanent teeth as a child and wonders if her son has any missing permanent teeth. The clinical evaluation of David’s oral cavity demonstrates evidence of poor oral hygiene, occlusal carious lesions in the 1st molar teeth, and marginal gingivitis.

No clinical or radiographic caries were found at that time and her periodontal status was good. Her chief complaint is discomfort and swelling behind the second molar teeth. The third molars are not erupted but she thinks they might be trying to come in. She is planning to attend an out-of-state college in a few months. Today your patient interview and oral examination reveal excellent general and oral health with the exception of inflammation and slight swelling in the third molar areas. No clinical carious lesions were found.
