This course will demonstrate the role of periodontal endoscopy in non-surgical treatment of periodontal disease and peri-implant diseases. The advanced diagnostics of magnified sub-gingival visualization allow the clinician to identify periodontal and peri-implant etiologies and potential complications with healing. The use of sub-gingival visualization allows the clinician to thoroughly decontaminate the tooth and implant surface. This creates an ideal environment for gingival attachment and in some cases, bone regeneration. The utilization of periodontal endoscopy in conjunction with other treatment aids such as lasers and biofilm management is a non–invasive, tissue sparing technique that restores health. Combined with individualized patient care to reduce host inflammation, enhanced visualization is a powerful tool that will prove to be the new standard of care in non-surgical treatment of periodontal and peri-implant disease.
