Ball (stud) attachment system vs Magnetic attachment system

Re-treatment: repair of attachment system (medium term) · Edentulous adults receiving mandibular implant overdentures (opposing conventional complete maxillary dentures)

It is very uncertain whether ball (stud) attachment system changes re-treatment: repair of attachment system (medium term) compared with magnetic attachment system (very low certainty).

Ball (stud) attachment system vs Telescopic attachment system

Prosthodontic maintenance: reline of implant overdenture (short term) · Edentulous adults receiving mandibular implant overdentures (opposing conventional complete maxillary dentures)

It is very uncertain whether ball (stud) attachment system changes prosthodontic maintenance: reline of implant overdenture (short term) compared with telescopic attachment system (very low certainty).

Ball (stud) attachment system vs Telescopic attachment system

Prosthodontic maintenance: matrix replaced (short term) · Edentulous adults receiving mandibular implant overdentures (opposing conventional complete maxillary dentures)

It is very uncertain whether ball (stud) attachment system changes prosthodontic maintenance: matrix replaced (short term) compared with telescopic attachment system (very low certainty).

Keratinocyte growth factor (KGF; palifermin or repifermin), intravenous vs placebo

Normalcy of diet (mean worst ability to eat, 1 to 4 scale) · Adults with cancer receiving treatment

Keratinocyte growth factor (KGF; palifermin or repifermin),… showed no clear difference in normalcy of diet (mean worst ability to eat, 1 to 4 scale) compared with placebo; GRADE not reported.

G‐CSF vs placebo or no treatment

Interruptions to cancer treatment (radiotherapy interruptions) · Adults with cancer receiving treatment

Granulocyte-colony stimulating factor (G-CSF) showed no clear difference in interruptions to cancer treatment (radiotherapy interruptions) compared with placebo or no treatment; GRADE not reported.

Granulocyte-macrophage colony-stimulating factor (GM-CSF), mouthwash vs Sucralfate mouthwash

Interruptions to cancer treatment · Adults receiving radiotherapy to the head and neck

Granulocyte-macrophage colony-stimulating factor (GM-CSF), mouthwash showed no clear difference in interruptions to cancer treatment compared with sucralfate mouthwash; GRADE not reported.

Analgesic (any: NSAID, paracetamol, local anaesthetic or opioid) vs placebo or control

Patient‐reported pain intensity or pain relief (VAS, NRS or categorical scale) · People undergoing orthodontic treatment (any age; 9 to 34 years in included studies)

Analgesic (any: NSAID, paracetamol, local anaesthetic or opioid) probably leads to lower pain intensity (VAS 0-100 mm) compared with control (placebo or no treatment) (moderate certainty).

Salivary flow rate (unstimulated) · Patients receiving radiotherapy on its own or in addition to chemotherapy to the head and neck region

Bethanechol led to higher salivary flow rate (unstimulated, ml/min) compared with artificial saliva; GRADE not reported.
