[Bone densitometry of periapical lesions]. / Densitométrie osseuse dans les lésions périapicales.

The aim of the work was to evaluate the bone density of chronic periapical lesions in the area of maxillary incisors and canines. Twenty-six radiographies were made in a systematic way in patients with periapical lesions and were valued using densitometry (0-256), the grey levels by computer and the analysis program image (IBAS 2000 Kontron, Germany), taking four values in each periapical lesion from the center to the periphery within the same radiography, by using the pseudocolor to identify the four areas, always in the same coloration. Correlation was proved with significative statistically results between lower densitometric values and osteolysis and radiolucency areas.
