Low‐level laser therapy vs Low-level laser therapy (LLLT) + calcium hydroxide

Radiological failure · Children with extensive decay involving the dental pulp in primary teeth

Low-level laser therapy (LLLT) showed no clear difference in radiological failure compared with low-level laser therapy (LLLT) + calcium hydroxide; GRADE not reported.

Low‐level laser therapy vs Placebo (sham) laser therapy

Patient-reported altered sensation (spontaneous or evoked: anaesthesia/paraesthesia/dysaesthesia/hyperalgesia/allodynia) · Patients of any age in any setting requiring intervention for iatrogenic injury to the inferior alveolar or lingual nerve

It is very uncertain whether low-level laser therapy (photon-plus GaAlAs diode laser; 70 mW… changes patient-reported altered sensation (spontaneous or evoked:… compared with placebo (sham) laser therapy (very low certainty).
