Summary
This study measured bone density in chronic periapical lesions using digital radiography. Lower bone density correlated with osteolysis and radiolucency, indicating bone loss in these dental infections.
Area of Science:
- Dentistry
- Oral Radiology
- Bone Densitometry
Background:
- Chronic periapical lesions are common dental conditions.
- Assessing bone density is crucial for understanding lesion progression.
- Limited data exists on bone density variations within these lesions.
Purpose of the Study:
- To evaluate bone density in chronic periapical lesions affecting maxillary incisors and canines.
- To correlate bone density measurements with osteolysis and radiolucency.
Main Methods:
- Twenty-six patients with periapical lesions underwent standardized radiography.
- Digital densitometry (0-256 grey levels) and image analysis (IBAS 2000) were employed.
- Four measurements were taken from the center to the periphery of each lesion.
Main Results:
- Statistically significant correlations were found between lower densitometric values and areas of osteolysis.
- Reduced bone density was associated with radiolucent regions within the lesions.
- A gradient of bone density was observed from the lesion center to the periphery.
Conclusions:
- Digital densitometry is effective in quantifying bone density changes in periapical lesions.
- Lower bone density in periapical lesions is indicative of active bone resorption (osteolysis).
- Findings support the use of densitometry for assessing the severity and extent of periapical bone destruction.
