Low polymerization shrinkage resin composite (silorane, ormocer, bulk-fill or other modified-monomer composite) vs Conventional methacrylate-based resin composite

Marginal discoloration · People with permanent posterior teeth restored with class I or II direct restorations

At 24 months, marginal discoloration did not differ significantly (7 groups; p = 0.77; ungraded).

Low polymerization shrinkage resin composite (silorane, ormocer, bulk-fill or other modified-monomer composite) vs Conventional methacrylate-based resin composite

Retention (restoration loss) · People with permanent posterior teeth restored with class I or II direct restorations

At 24 months, retention did not differ significantly between the composites (6 studies; ungraded).

Low polymerization shrinkage resin composite (silorane, ormocer, bulk-fill or other modified-monomer composite) vs Conventional methacrylate-based resin composite

Postoperative sensitivity · People with permanent posterior teeth restored with class I or II direct restorations

Postoperative sensitivity at 12 months did not differ significantly between low polymerization shrinkage and methacrylate composites (OR 1.65, 95% CI 0.71 to 3.81; Moderate certainty).

Populations with a lower proportion of university-educated people (<33.78% with university level) vs Not applicable

Dental caries · Adult participants in 25 meta-regression studies

The Model 1 adjusted meta-regression coefficient for lower university education was -4.132903.

Low level of schooling (>33.60% of the population) vs Not applicable

Dental caries · Adult participants in 25 meta-regression studies

The unadjusted meta-regression coefficient for low schooling was -2.301079.

Gamified mobile health app vs Conventional method

Plaque control · Children or adolescents

One RCT reported superior plaque control with a gamified mobile health app versus a conventional method; no effect estimate or GRADE assessment was reported.

Composite strip crown (CSC) with a post (microhybrid composite resin, Amelogen) vs Post type: composite post (CP) vs fibre post (FP) vs reverse metal post (RMP)

Treatment failure (annual failure rate) · Children with severely decayed maxillary primary incisors treated by pulpectomy (non-vital pulp therapy)

Composite strip crowns with composite posts had a low annual failure rate (2.3%) in maxillary primary incisors after pulpectomy (single high-risk-of-bias RCT; low quality of evidence; not GRADE-rated).

Dental examinations at three-month intervals and preventive treatments vs usual care

MRONJ (incidence proportion) · Men with metastatic prostate cancer receiving intravenous zoledronic acid (at risk of MRONJ)

It is very uncertain whether dental examinations at three-month intervals and preventive treatments changes MRONJ (incidence proportion) compared with standard care (very low certainty).

Conventional GIC vs Amalgam or metal-reinforced GIC

Treatment failure (annual failure rate) · Children with previously unrestored, vital carious lesions in primary teeth (no pulp therapy); aged 1.5-11 years

Conventional GIC had an annual failure rate of 7.6-16.6% (2 RCTs) and failed more than amalgam in one trial; low quality of evidence (ungraded).

Dental examinations at three-month intervals and preventive treatments vs usual care

MRONJ (incidence rate: cases per patient-year) · Men with metastatic prostate cancer receiving intravenous zoledronic acid (at risk of MRONJ)

It is very uncertain whether dental examinations at three-month intervals and preventive treatments changes MRONJ (incidence rate: cases per patient-year) compared with standard care (very low certainty).

Amalgam vs Preformed metal crown (PMC)

Treatment failure (annual failure rate) · Children with carious primary molars treated by pulpotomy (vital pulp therapy)

Preformed metal crowns had a low annual failure rate (2.4%) in primary molars after pulpotomy, lower than amalgam in the same trial (single high-risk-of-bias RCT; low quality of evidence; not GRADE-rated).

Selective carious tissue removal (selective excavation, SE) vs Hall Technique (sealing with a preformed metal crown)

Failure of therapy · Children and/or adults with permanent or primary teeth, vital (sensitive) pulps, and cavitated or dentine carious lesions conventionally…

It is very uncertain whether selective carious tissue removal (selective excavation, SE) changes failure of therapy compared with hall Technique (sealing with a preformed metal crown) (very low certainty).

Non-selective carious tissue removal and conventional restoration (CR) vs Hall Technique (sealing with a preformed metal crown)

Failure of therapy · Children and/or adults with permanent or primary teeth, vital (sensitive) pulps, and cavitated or dentine carious lesions conventionally…

Non-selective carious tissue removal and conventional restoration (CR) may leads to higher failure of therapy compared with hall Technique (sealing with a preformed metal crown) (low certainty).
