Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

Review question

ElementPlanned (methods)Found (results)
PopulationAdults (> 18 years) with a clinical diagnosis of periodontitis (aggressive or chronic per 1999 classification, or Stage II/III per 2017 World Workshop); adults with peri-implant mucositis; adults with peri-implantitis; included regardless of smoking status; excluded systemic disease/medication affecting periodontal disease, antibiotics within prior 6 months, and necrotising periodontitisAdults with periodontitis in the active (non-surgical) phase (n=44 studies); adults with periodontitis in the supportive/maintenance phase (n=7 studies); adults with peri-implant mucositis (n=1 study, Al Rifaiy 2022, e-cigarette users); 50 RCTs, 1407 participants total (studies ranged from 10 to 88 participants); mostly non-smokers; none on antibiotics in the prior 6 months
InterventionAdjunctive antimicrobial photodynamic therapy (aPDT) applied subgingivally after subgingival or submucosal instrumentation (SI); during active (non-surgical anti-infective) treatment or supportive (maintenance) treatment; single or multiple sessions; any photosensitising agent; laser or LED at any wavelengthAdjunctive aPDT after SI, single session (n=39 studies); multiple sessions of 2 to 4 (n=11 studies); one study included both single and multiple sessions; various photosensitisers with diode laser/LED devices; SI by hand or power-driven instrumentation, or both
ComparisonSubgingival/submucosal instrumentation (SI) alone (negative control; hand or power-driven, or both); or SI plus sham/placebo aPDT (sham laser device and sham photosensitising agent)SI alone / negative control (n=45 studies); SI plus placebo/sham aPDT (n=5 studies)
OutcomesCritical: Change in probing pocket depth (PPD)/probing depth (PD); Change in bleeding on probing (BOP); Change in clinical attachment level (CAL/RAL); Change in gingival recession (REC); Pocket closure (proportion of pockets changing from >= 5 mm to <= 4 mm); Any adverse effect related to aPDT. Other important: Change in bone level (peri-implantitis); Patient satisfaction; Quality of lifeChange in PPD (n=15 studies at 6 months; n=35 at 3 months); Change in BOP (n=5 at 6 months; n=11 at 3 months); Change in CAL (n=13 at 6 months; n=34 at 3 months); Change in REC (n=4 at 6 months; n=13 at 3 months); Pocket closure (n=3 at 3 months; n=0 at 6 months); Any adverse effect related to aPDT (n=24 active, n=3 supportive); Patient satisfaction (n=0); Quality of life (n=0); Change in bone level (n=0)
Study designsRandomised controlled trials (RCTs), parallel-group and split-mouth designs, with at least one month of follow-up (cross-over studies excluded)RCT, split-mouth design (n=32); RCT, parallel-group design (n=18)
TimingChange from baseline to three months or six months (six months prioritised for GRADE/SoF); bone level to end of studyChange from baseline measured at 3 months and 6 months (6 months prioritised for GRADE); the single peri-implant study reported at 3 months only
