A short-term longitudinal study was carried out to assess how microbiological and clinical characteristics, measured surrounding periodontal sites with amalgam class II fillings intentionally made to overhang, vary following their replacement with a correct form of filling. The results of the study showed a significant reduction of the total bacterial count and the percentages of Gram-negative and anaerobic organisms spreading from overhanging fillings to non-overhanging fillings. The paper concludes that, as has been already demonstrated in the case of onlays, there are both qualitative and quantitative variations in the subgingival plaque in the presence of overhanging fillings which can lead to periodontal damage.
开展了一项短期纵向研究，以评估在故意制作成悬突的II类汞合金充填物周围的牙周部位进行测量的微生物学和临床特征，在更换为正确形状的充填物后会如何变化。研究结果显示，从悬突充填物扩散到非悬突充填物的细菌总数以及革兰氏阴性菌和厌氧菌的百分比显著降低。该论文得出结论，正如嵌体的情况已经表明的那样，存在悬突充填物时龈下菌斑在定性和定量方面都会发生变化，这可能导致牙周损害。
