Dental cavity liner (e.g. calcium hydroxide, glass ionomer, resin-modified glass ionomer, or flowable composite) placed under the restoration vs No cavity liner or a different liner material

Restoration longevity · Patients with deep caries lesions in mature or immature permanent (posterior) teeth, with no symptoms or reversible pulpitis

Cavity liners may make little or no difference to restoration longevity (high success across groups; low certainty).

Dental cavity liner (e.g. calcium hydroxide, glass ionomer, resin-modified glass ionomer, or flowable composite) placed under the restoration vs No cavity liner or a different liner material

Treatment failure · Patients with deep caries lesions in mature or immature permanent (posterior) teeth, with no symptoms or reversible pulpitis

The evidence is very uncertain about the effect of cavity liners on treatment failure; no significant difference between lined and unlined (or differently lined) restorations was found (very low certainty).

Dental cavity liner (e.g. calcium hydroxide, glass ionomer, resin-modified glass ionomer, or flowable composite) placed under the restoration vs No cavity liner or a different liner material

Postoperative hypersensitivity (POH), patient-reported (VAS score) · Patients with deep caries lesions in mature or immature permanent (posterior) teeth, with no symptoms or reversible pulpitis

The evidence is very uncertain whether cavity liners reduce postoperative hypersensitivity; no significant difference was found overall (very low certainty).

Dental cavity liner (e.g. calcium hydroxide, glass ionomer, resin-modified glass ionomer, or flowable composite) placed under the restoration vs No cavity liner or a different liner material

Tooth survival · Patients with deep caries lesions in mature or immature permanent (posterior) teeth, with no symptoms or reversible pulpitis

Cavity liners may make little or no difference to tooth survival (99.4% survival across groups; low certainty).

Dental cavity liner (e.g. calcium hydroxide, glass ionomer, resin-modified glass ionomer, or flowable composite) placed under the restoration vs No cavity liner or a different liner material

Oral health-related quality of life · Patients with deep caries lesions in mature or immature permanent (posterior) teeth, with no symptoms or reversible pulpitis

No included study reported oral health-related quality of life (a planned outcome), so no evidence is available.

Secondary prevention of caries · Patients with deep caries lesions in mature or immature permanent (posterior) teeth, with no symptoms or reversible pulpitis

Cavity liners may make little or no difference to secondary caries prevention (~100% prevention across groups; low certainty).

A 10-minute film followed by the same 30-minute one-to-one hygienist instruction on sugar consumption and dental health, plus oral hygiene, fluoride and regular visits (a multi-intervention) vs No special instructions (control)

Mean sugar consumption (self-reported, 1 to 5 scale; higher score = more positive behaviour) · Adults newly registered at a group dental practice in a suburban Dutch village, the Netherlands

Anorexia nervosa (as exposure; diagnosed by DSM-III/III-R/IV/V) vs Healthy controls

Salivary flow rate (stimulated) · Patients with anorexia nervosa aged >=12 years (mean age ~18.4; entirely female in reported data), general community-dwelling population

Stimulated salivary flow rate was significantly lower in anorexia nervosa patients than controls, but only unstimulated flow was meta-analyzed; this outcome is ungraded.

Anorexia nervosa (as exposure; diagnosed by DSM-III/III-R/IV/V) vs Healthy controls

Salivary flow rate (unstimulated) · Patients with anorexia nervosa aged >=12 years (mean age ~18.4; entirely female in reported data), general community-dwelling population

Anorexia nervosa probably reduces unstimulated salivary flow rate versus healthy controls (MD -0.27 ml/min, 95% CI -0.31 to -0.24; moderate certainty).

Pentoxifylline vs Placebo or no active treatment

Difficulty in swallowing (participant-reported proxy) · People of any age with a confirmed diagnosis, by clinical examination and biopsy, of oral submucous fibrosis (OSF)

Pentoxifylline led to lower difficulty in swallowing (participant-reported proxy) compared with placebo or no active treatment; GRADE not reported.

Antioxidants (lycopene, curcumin, Oxitard) vs Placebo or no active treatment

Difficulty in swallowing (participant-reported proxy) · People of any age with a confirmed diagnosis, by clinical examination and biopsy, of oral submucous fibrosis (OSF)

Antioxidants (lycopene, curcumin, Oxitard) led to lower difficulty in swallowing (participant-reported proxy) compared with placebo or no active treatment; GRADE not reported.

Oxitard (antioxidant) vs Topical aloe vera gel

Difficulty in swallowing (participant-reported proxy) · People of any age with a confirmed diagnosis, by clinical examination and biopsy, of oral submucous fibrosis (OSF)
