Title Non-Surgical Periodontal Therapy Is As Effective As Surgical Periodontal Therapy In Treating Patients With Furcation Involvements
Clinical Question In a middle aged patient with mild furcation on multi-rooted teeth, does periodontal surgery treatment improve the longevity of teeth better than scaling and root planing?
Clinical Bottom Line Non-surgical conservative therapy is as effective as surgical periodontal therapy in preventing loss of furcation-involved teeth. (See Comments on the CAT below)

Key resultsThe survival rate of molars treated non-surgically was >90% after 5-9 years. The corresponding values for the different surgical procedures were: 1) Surgical therapy- 43.1%-96%, observation period: 5-53 years 2) Tunneling procedures: 42.9%-92.9%, observation period: 5-8 years 3) Surgical resective procedures including amputation(s) and hemi-sections: 62%-100%, observation period: 5-13 years 4) Guided tissue regeneration (GTR): 83.3%-100%, observation period: 5-12 years. The most frequent complications included caries in the frucation area after tunneling procedures and root fractures after root-resective procedures.

Comments on
The Evidence
The Huynh-Ba article reported a systematic review of various treatments for furcation involvement on multi-rooted teeth, including 22 trials, comparing non-surgical periodontal treatment to several different types of surgical treatment. The author reported a comprehensive, detailed search for relevant trials and assessed the individual studies for validity using clear criteria, and found the evidence to be of high quality. No meta-analysis was done.
Applicability Subjects were representative of patients that have furcation involvement on multi-rooted teeth. The benefits patients could potentially experience are improvement in the longevity of furcation-involved teeth with both non-surgical conservative therapy and surgical periodontal therapy. However, other outcomes could be complications including recurrence of periodontitis, periodontal abscesses, combined endodontic-periodontal lesions, caries, and root fractures.

A systematic review done by Needleman in 2010 ( 20577278 ) further supported the conclusions reached in this CAT. This review analyzed twenty-two publications and found that the survival rate for non-surgically treated molars with furcation involvement was >90%. Nonsurgical mechanical debridement is a successful treatment for initial furcation involvement and it avoids the complications associated with resective surgeries.
