Comparative Microflora Assessment of Natural Sulci vs. Deep and Shallow Implant Sulci in Partial Edentulousness.

The main cause of peri-implantitis and crestal bone resorption is bacterial infection. The present study aimed to comparatively assess the microbiological parameters in sulci around teeth and crowns supported by dental implants and also compare microbiological parameters around deep and shallow implant sulci. In this cross-sectional study, 34 partially edentulous patients with a total of 72 implants (22 deep vs.
