The effectiveness of mouthwash on orthodontic and prosthetic complications: a systematic review

---

BACKROUND AND AIM

The present study aimed to determine the effectiveness of mouthwashes on the complications of orthodontic treatments and dental prostheses, in addition to filling research gaps, to identify and present scientific methods to improve oral health.

METHODS

The present study investigated the issue by reviewing ten articles published from 2001 to 2024 with keywords including “Oral Wash Serum”, “Oral Dental Health”, “Orthodontics”, “Prosthetics and “Dental Abnormalities” in ubMed/Scopus, MEDLINE (Ovid), Cochrane Library, and Embase.

RESULTS

Studies have shown that herbal mouthwashes, such as propolis and Matricaria chamomile, have similar effects to CHX in reducing plaque and gingivitis. Rinsing with aloe vera or chlorine dioxide also showed a reduction in plaque and bleeding indices and could be a suitable alternative with minimal side effects. Evidence shows that rinsing duration and frequency of use are important factors in the effectiveness of mouthwashes. Regular use twice daily significantly reduces indicators of gingivitis. Overall, mouthwashes are an effective adjunct to gum health care in orthodontic patients.

CONCLUSIONS

Proper use of mouthwash during orthodontic treatment plays an important role in reducing dental plaque, preventing gingivitis, and improving oral health. Choosing the right type of mouthwash, following instructions carefully, and paying attention to oral hygiene can optimize orthodontic treatment outcomes and improve patients’ quality of life.

CLINICAL SIGNIFICANCE

Regular and correct use of mouthwashes effectively reduces dental plaque, inflammation, and gingival bleeding in patients undergoing orthodontic and prosthetic treatments. Using herbal mouthwashes can be a good alternative to chemical mouthwashes such as chlorhexidine, especially in sensitive patients or those who avoid long-term use of chemical products due to side effects.
