Systematic review of the adjunctive effects of antimicrobial photodynamic therapy (aPDT) for periodontal treatment (scaling root planing (SRP)).

Author and Year (Ref.)	Treatment Arms	Results
Smiley et al., 2015 [14]	Test: SRP + aPDT; Control: SRP	aPDT with a diode laser adjunctive to SRP had a beneficial effect with a moderate level of certainty
Sgolastra et al., 2013 [12]	Test: SRP + aPDT; Control: SRP	The use of adjunctive aPDT with conventional SRP provided short-term benefits
Sgolastra et al., 2013 [79]	Test 1: SRP + aPDT; Test 2: aPDT; Control: SRP	The use of aPDT adjunctive to conventional treatment provided short-term benefits. There was no evidence of effectiveness for the use of aPDT as an alternative to SRP
Azarpazhooh et al., 2010 [43]	Test 1: SRP + aPDT; Test 2: aPDT; Control: SRP	aPDT as an independent treatment or an adjunct therapy to SRP was not superior to SRP
Atieh et al., 2010 [80]	Test: SRP + aPDT; Control: SRP	The use of aPDT in conjunction with SRP was associated with significant clinical parameter improvements
