Subepithelial connective tissue graft (palate) at implant placement vs No augmentation

Soft tissue thickness change · Partially edentulous patients receiving posterior mandibular implants

Subepithelial connective tissue graft (palate) at implant placement led to lower soft tissue thickness change compared with no augmentation; GRADE not reported.

Higher consumption of snacks / sugar / soft drinks vs Lower consumption

Dental caries · Healthy children and adolescents in the United Arab Emirates

Higher snacking and soft-drink/sugar consumption were associated with more caries in most studies, though one study found no association with sweet-consumption frequency (narrative synthesis; not GRADE-rated).

Minimally invasive caries removal (MIT): selective removal to soft dentin, self-limiting chemomechanical removal, or partial/incomplete caries removal vs Conventional caries removal (CT): selective removal to firm dentin, stepwise excavation, or complete caries removal

Pulp exposure rate · Patients with deep carious lesions in permanent (mainly posterior) teeth

Minimally invasive caries removal was associated with a lower mean pulp exposure rate than conventional removal (1.2% vs 8.1%), but the difference was not statistically significant (Wilcoxon, p = 0.068); certainty of evidence was not graded.

Minimally invasive caries removal (MIT): selective removal to soft dentin, self-limiting chemomechanical removal, or partial/incomplete caries removal vs Conventional caries removal (CT): selective removal to firm dentin, stepwise excavation, or complete caries removal

Treatment success (caries lesion arrest or restoration survival) · Patients with deep carious lesions in permanent (mainly posterior) teeth

Minimally invasive caries removal showed a marginally higher mean restoration success rate than conventional removal (83.6% vs 75.4%), but the difference was not statistically significant (Mann-Whitney U, p > 0.05); certainty of evidence was not graded.

Silver diamine fluoride (SDF) vs Other methods (pooled: ART/glass ionomer cement, nano-silver fluoride, sodium fluoride varnish, placebo)

Adverse effects (tooth staining and other side effects) · Children and adults with active dental caries (aged 1-50; mostly preschool/school children with primary dentition)

SDF commonly causes black staining of arrested lesions; only mild, transient adverse events were reported, with no major adverse events (ungraded).

Concentrated growth factor (CGF) and primary wound closure vs primary closure

Healing of MRONJ (soft tissue healing) · Women with osteoporosis and established MRONJ

It is very uncertain whether concentrated growth factor (CGF) and primary wound closure changes healing of MRONJ (soft tissue healing) compared with primary wound closure only (very low certainty).

Soft tissue pathology · Children with carious vital pulp exposure in primary incisors

No statistically significant difference in soft tissue pathology between pulpotomy and pulpectomy (RR 3.11, 95% CI 0.54 to 17.7; ungraded).
