The Radiographic Evaluation of Enamel Matrix Derivative for the Treatment of Periodontal Intrabony Defect in Human: A Retrospective Study
摘要
Previous studies have demonstrated that enamel matrix derivative (EMD) has the ability to improve periodontal parameters when used to treat intrabony defects. Limited data about digital radiographic evaluation for the difference between the baseline and post-operative of one-year is available. The aim of the present study was to assess the radiographic finding following EMD treatment at sites with intrabony defects in human after one year and compare with the baseline. A total of 26 intrabony defects in 17 individuals (9 females, 8 males), treated by EMD, were examined for digital radiographic evaluation. The standard periapical radiographs at the mesial and distal sites were determined by the electric digital caliper at 3x times magnification. The measurement of CEJ to root apex (RL), CEJ to bony defects (BD) was performed. The radiographic linear bone loss (RLBL) was present as BD/RL (%). The radiographic clinical attachment level (RCAL) was also calculated. The difference of RLBL nor RCAL. The difference of gain of RCAL between and post-operative was significant (P＜0.0001). The age was not correlated with RLBL nor RCAL. The difference of gain of RCAL between female and male was not significant. The present study concluded that treatment of periodontal intrabony defects using EMD was clinically predictable in radiographic evaluation.
