Mortality (overall survival) · Adults with oral cavity cancer (tongue or floor of mouth) and clinically negative neck nodes
Elective neck dissection (at time of primary tumour resection) probably leads to lower mortality (overall survival) compared with therapeutic (delayed) neck dissection (moderate certainty).

Disease-free survival · Adults with oral cavity or oropharyngeal cancer
Sentinel node biopsy (neck dissection only if biopsy positive) showed no clear difference in disease-free survival (new disease, progression, and mortality) compared with elective neck dissection (low certainty).

Locoregional recurrence · Adults with oral cavity cancer (tongue or floor of mouth) and clinically negative neck nodes
1 finding from 1 review
Locoregional recurrence: data not presented usably and inconsistent; Pandey 2018 no difference (3/12 vs 3/20); Rastogi 2018 lower recurrence with superselective (Kaplan-Meier P<0.05); 72 participants (2 RCTs).

Duration of orthodontic treatment: alignment stage (mandibular arch) · Adolescents and adults with malocclusion undergoing fixed orthodontic appliance treatment
It is very uncertain whether light-emitting diode (LED) photobiomodulation changes duration of orthodontic treatment: alignment stage (mandibular arch) compared with conventional orthodontic appliance treatment (very low certainty).
