The antibacterial effect of chlorohexidine, Er:YAG laser and diode laser 980 nm as dental cavity disinfectants of dentine: an in vitro study.

ABSTRACT:

Objectives

Comparison between different disinfection modalities in reducing Streptococcus mutans count within dental cavities.

Research question

whether using an antibacterial agent has a value in reducing the bacterial load in the dental cavity and what is the best modality. Cariogenic bacteria can remain viable in the dentine even after complete removal of caries, so the use of cavity disinfectants before restoration placement is crucial, such as chlorohexidine, Er:YAG and Diode laser 980 nm. The aim of this study was to evaluate and compare the antibacterial effect of chlorohexidine, Er:YAG and diode laser 980 nm as cavity disinfectants.

Methods

Forty sound extracted human primary molars were randomly assigned to four groups (ten teeth in each group); group I: (neg
