摘要: The objective of this retrospective study was to evaluate the influence cemental tear as a risk factor in periodontal attachment loss. Seventeen extracted, singlerooted teeth showing loss and having one surface opposite intact were examined. stained 0.1% toluidine blue visualize attached ligament remnants examined light microscope under incident light. On each tooth, measured along long axis root from cemento-enamel junction most coronal level on well defect surfaces. Cemental surfaces demonstrated significantly greater than (P < 0.0001). In specimen, fragment partially after extraction procedure. This specimen processed for microscopy determine location fracture. Histological examination clea...
