OBJECTIVE
To assess the effect of different stages of intervention on volatile sulphur compounds (VSCs) of periodontitis patients with halitosis, before and after non-surgical periodontal therapy.
METHODS
This clinical trial included 18 adults with chronic periodontitis and halitosis. After initial examination, patients received oral hygiene (OH) instructions and tongue cleaner. One week later, non-surgical periodontal therapy was completed within 48 h. Measurements were at baseline, 1 week after OH, 1 and 6 weeks post therapy. These included simplified plaque index (sPlI), probing pocket depth (PPD), bleeding on probing (BoP), Winkel Tongue Coating Index (WTCI), organoleptic scores (OLSs) of nose and mouth air and VSCs.
RESULTS
sPlI, BoP, WTCI, OLS of the mouth air and VSCs showed significant differences (p < 0.05), even after 1 week of OH. A further significant decrease was determined 1 week after non-surgical therapy for WTCI, OLS (nose and mouth air) and methyl mercaptan concentration. A significant decrease, 6 weeks post therapy, was observed for sPlI, BoP, WTCI, PPD, OLS of the nose and mouth air and VSCs (p < 0.05).
CONCLUSIONS
Oral hygiene and tongue cleaning improve the OLSs of the mouth air and reduce VSCs. Periodontal therapy further improves the OLSs and reduces the concentration of VSCs.
