Introduction As a modern alternative to conventional therapies, the Laser Assisted New Attachment Procedure LANAP protocol utilizes an NdYAG laser to treat periodontal disease. Purported advantages of LANAP include improved access to root surfaces, more predictable hemostasis, and increased patient acceptance due to a lack of need for conventional surgical flaps and suturing. Despite widespread use of the LANAP protocol, there is limited research that reports on general treatment outcomes, post-operative pain, and rapidity of healing. Objectives The primary purpose of this study is to investigate the clinical healing and resolution of periodontal disease after LANAP by comparing full-mouth clinical measurements at baseline and 12 months after treatment. Secondarily, the study will assess the patient-reported outcome measures of pain and perceived improvement in oral health. Methods Thirty patients with generalized Stage II to Stage IV Periodontitis will be enrolled in the study. Qualifying subjects will have at least 4 sites per quadrant with a probing depth of 4 mm and bleeding on probing. Full-mouth clinical measurements recorded at baseline, including plaque, probing depth, clinical attachment level, recession, bleeding on probing, purulence, mobility, and furcation involvement, will be compared to measurements gathered 12 months after LANAP therapy. Additionally, after each LANAP procedure, the patients level of post-operative pain will be recorded via a visual analog scale VAS-based pain questionnaire. Lastly, at baseline, 6, and 12 months after treatment, patients perceived improvements in their oral health status will be analyzed through an oral health impact profile OHIP-14 questionnaire. Results This human research study is pending approval by the Institutional Review Board.
