Periodontal Diagnosis in a Young Patient with an Unusual Presentation of Dental Calculus.

This report details the periodontal diagnosis and phase I treatment of an 18-year-old male patient dissatisfied with his teeth. The patient, on 20 mg Isotretinoin for acne, exhibited heavy calculus and plaque, generalized gingival inflammation, carious lesions, remaining roots, an anterior open bite, bilateral cross-bite, and an ectopically erupted tooth (#25). Initial scaling enabled examination, revealing FMPS and FMBS of 100%, PD of 1-7 mm, gingival recession of 1-2 mm, a maximum CAL of 6 mm, and radiographic bone loss of around 48% of teeth, reaching up to 15% of the root length.
