The axial, sagittal and coronal reformations shown above depict a generalized cortical of bone porosity and lose trabeculation, features consistent with osteoporosis.

Patient Presentation

A 79yo Caucasian female presented for evaluation and possible endodontic treatment of mandibular left first molar. There was no mention of osteoporosis in her medical history. Osteoporosis is a systemic disease characterized by low bone mass and micro-architectural deterioration, with a consequent increase in bone fragility and features.*

The mandibular cortex is generally porous. Surrounding periodontal structures of visualized teeth are within normal limits. Some lose bone marrow space is noted between the apices of the molars and the mandibular canal. 

Impressions and recommendations

Mandibular cortical porosity and lose trabeculation are highly suggestive of osteoporosis. Referral to patient’s physician for further evaluation was recommended.
