A comparative in vitro study of microscope-enhanced root scaling and conventional root scaling

Objectives: The benefits of surgical microscope applied to periodontal therapy were mainly based on subjective statements made by patients or periodontists. In this work, we conducted a quality scientific evaluation to determine the advantages of surgical microscope application during root surface conditioning of extracted teeth. Methods: Extracted teeth were assigned into four groups: NC group, normal teeth( A group ); PC group, untreated periodontitis teeth(B group); Macro group, the root surface instrumented with the naked eyes(C group); Micro group, the root surface instrumented with a microscope(D group). Results: Methylene blue staining and SEM displayed fewer residual calculi on the root surface in the Micro group, compared with that in the Macro group (p
