The effect of professional tooth cleaning or non-surgical periodontal therapy on oral halitosis in patients with periodontal diseases. A systematic review.

Abstract in brief

• This systematic review examined how professional tooth cleaning and nonsurgical periodontal treatments like scaling and root planing affect bad breath caused by periodontal diseases, focusing on reducing volatile sulphur compounds.
• The review included only high-quality studies (like randomized controlled trials) that measured changes in bad breath through specific tools, and found that these treatments, especially when combined with oral hygiene instructions, effectively reduced bad breath indicators regardless of additional measures like tongue cleaning or mouth rinses.
• Overall, the evidence suggests that professional dental cleanings and periodontal treatments can help improve bad breath in patients with gum issues, reinforcing the importance of such procedures alongside good oral hygiene practices.]
