Full-mouth disinfection (FMD): scaling/root planing (subgingival instrumentation) of all quadrants within 24 hours plus adjunctive antiseptic (chlorhexidine) treatments (rinsing, pocket irrigation, tongue/tonsil brushing) vs Quadrant scaling and root planing (control): SRP of each quadrant in separate sessions at least one week apart

Change in probing pocket depth (PPD) · Adults with a clinical diagnosis of (chronic) periodontitis (1999 classification); studies of aggressive periodontitis, systemic disorders…

Full-mouth disinfection (FMD): scaling/root planing (subgingival… showed no clear difference in change in probing pocket depth (PPD) compared with quadrant scaling and root planing (control): SRP of each quadrant in… (low certainty).

CBT vs alternative treatment

Mental distress · People aged 12 years and over with painful TMD lasting 3 months or longer

Cognitive behavioural therapy (CBT) may leads to lower psychological distress at follow-up compared with alternative (active) treatment (e.g. oral splint, medication,… (low certainty).

Pulpotomy with mineral trioxide aggregate (MTA) vs Pulpotomy with Calcium Enriched Mixture (CEM)

Overall success (composite of clinical and radiographic success) · Human permanent teeth with irreversible pulpitis due to carious pulp exposure

MTA and CEM did not differ significantly in pulpotomy success (indirect comparison); ungraded.

Periodontal treatment (subgingival instrumentation, with or without antimicrobials/surgery) vs usual care or no treatment

Gingival index (GI) · People with diabetes mellitus (type 1 or type 2, mostly type 2) and periodontitis, at least 16 years of age

Periodontal treatment (subgingival instrumentation, with or without… led to lower gingival index (GI) compared with no active intervention/usual care; GRADE not reported.

Cleft lip and/or palate (CL/P) vs No cleft lip and/or palate (non-CL/P)

Early childhood caries experience (mean dmft) · Children in the primary dentition with non-syndromic cleft lip and/or palate (CL/P) and comparable children without CL/P

In the combined primary and mixed dentition, there was no evidence of a difference in caries experience between children with and without CL/P (SMD 0.09, 95% CI -0.59-0.76; 5 studies; ungraded).

Transillumination and OCT vs Reference standard (histology, excavation, or enhanced visual examination)

Specificity for detection of enamel caries · Asymptomatic children or adults suspected of enamel caries (clinical studies); extracted teeth (in vitro studies)

Transillumination and OCT had a summary specificity of 0.82 (95% CrI 0.68, 0.91) for detecting enamel caries; low certainty.

  • Psychological therapies for temporomandibular disorders (TMDs) 2022 · Cochrane All outcomes
    Only 1 study reported adverse events as an outcome (Litt 2010): it found worsening symptoms in 13 people treated with an oral splint (as part of standard treatment) and 4 people treated with CBT.

CD4+ T-cell count below 250 cells/mm3

Prior application of silver diamine fluoride (SDF), with or without a rinsing step vs No prior SDF application (untreated dentin control)

Immediate bond strength (MPa) · Dental adhesives/resin composite bonded to dentin (in vitro), sound or caries-affected

Prior SDF application significantly reduces the immediate bond strength of adhesives to dentin overall (MD 7.12 MPa favoring untreated dentin, 95% CI 1.38 to 12.85; ungraded), with very high heterogeneity (I2=98%).

Oral hygiene measured by mean gingival scores · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)

The effect of school-based interventions on gingival scores is uncertain and not statistically significant (SMD 0.12; very low certainty).
