Prosthetic failure (2 years) · Patients who have had radiotherapy and who have missing teeth that require replacement with osseointegrated dental implants

It is very uncertain whether hyperbaric oxygen (HBO) therapy changes prosthetic failure compared with no HBO therapy (very low certainty).

Acupuncture vs sham

Unstimulated whole saliva (UWS) · Adults with dry mouth due to radiotherapy (head and neck cancer) or Sjogren's Syndrome

Acupuncture may leads to higher unstimulated whole saliva (UWS) compared with placebo (sham acupuncture) (low certainty).

Two miniplates (transbuccal approach) vs One miniplate plus two screws (intraoral approach at external oblique ridge)

Post-operative infection · Adults with fractures of the mandibular angle

Two miniplates (transbuccal approach) showed no clear difference in post-operative infection compared with one miniplate plus two screws (intraoral approach at external…; GRADE not reported.

2 mm titanium plates vs 2.5 mm bioresorbable plates

Restoration of function (inability to chew hard food) · Adults (16 to 68 years) with mandibular fractures excluding condylar involvement

Electrostimulation (device) vs Placebo (sham/placebo device)

Stimulated whole saliva (SWS) · Adults with dry mouth due to Sjogren's Syndrome

It is very uncertain whether electrostimulation (device) changes stimulated whole saliva (SWS) compared with placebo (sham/placebo device) (very low certainty).
