Abstract

BACKGROUND:

The aim of this systematic review is to evaluate the long term (≥ 2 years) effect of four surgical and non-surgical therapies in treating periodontal disease.

METHODS:

An electronic search of four databases and a hand search of peer-reviewed journals for relevant articles were conducted. Prospective human controlled clinical trials were included that compared surgical therapy to non-surgical therapy in ≥ 10 patients diagnosed with chronic periodontitis with a follow-up period of ≥ 2 years and that reported change in probing depth (PD) and clinical attachment level (CAL) after the therapy. Random effect meta-analysis was performed to compare the outcome of surgical and non-surgical therapy in shallow, moderate, and deep PD.

RESULTS:

Eight human prospective clinical trials were included. In 1- to 3-mm PD, scaling and root planing (SRP), modified Widman flap (MWF), and osseous surgery (OS) resulted in 23.2%, 39.4%, and 61.39% CAL loss, respectively; SRP, MWF, and OS resulted in increased mean PD of 2.5%, 3.3%, and 6.3%, respectively. In 4- to 6-mm PD, SRP, MWF, and OS resulted in 8.4%, 6.5%, and 5.22% CAL gain, respectively; SRP, MWF, and OS resulted in 18.7%, 25.4%, and 30.8% PD reduction, respectively. In PD ≥ 7 mm, SRP, MWF, and OS resulted in 9.8%, 14.2%, and 9.38% CAL gain, respectively; SRP, MWF, and OS resulted in mean PD reduction of 21.6%, 33.1%, and 42.8%, respectively.

CONCLUSIONS:

Surgical therapy had significantly more CAL loss than non-surgical therapy in shallow PD. In moderate PD, MWF had significantly more PD reduction than SRP, and there was significantly less CAL gain with surgical therapy. In deep PD, OS had significantly higher PD reduction than SRP.
