Subgingival laser irradiation + povidone-iodine vs SRP

Dentist-reported organoleptic test (OLT) score (scale 0 to 5) · Adolescents and adults aged over 16 years with clinical or self-assessed halitosis of oral origin; excluding induced or physiological…

It is very uncertain whether subgingival laser irradiation + povidone-iodine changes dentist-reported organoleptic test (OLT) score (scale 0 to 5) compared with SRP alone (very low certainty).
