An analogical study of two mouth rinses on plaque and gingivitis among school children aged 12-15 years in Jamshedpur, Jharkhand, India
Context and Background: Mechanical methods are known for prevention and control of periodontal diseases since long. It is important to consider these procedures too yet they are labor-intensive and difficult for many patients. Based upon this consideration and aiming to make dental plaque control more accessible to a significant proportion of population, less labor-intensive methods are highly desirable. Consequently, efforts have been made to utilize chemical agents in conjunction with or even instead of mechanical plaque control procedures and have been tested by incorporating them into mouthwashes.
Methods: Using a double blind randomized controlled clinical trial, 60 subjects aged 12-15 years were grouped into 3 groups: CHX; CHX+NaF; and Placebo. In each one of the 3 groups, the subjects discontinued all oral hygiene measures and continued with the experimental set-up randomly assigned. Levels of gingivitis and plaque scores were assessed at baseline and at the end of 1and 3 months by using Silness and Loe Plaque Index and Loe and Silness Gingival Index.
Results: The effectiveness of CHX+NaF mouth rinse is superior with regard to inhibition of plaque and gingivitis scores as compared to CHX alone. For CHX+NaF, mean reduction was 1.37854 whereas for CHX, it was 1.18486 for plaque score between baseline and 3 months. For gingivitis score, the mean reduction was 1.0516 for CHX+NaF whereas 1.0659 for CHX between baseline and 3 months.
Conclusion: Chlorhexidine in combination with active ingredient Sodium Fluoride inhibit the plaque and gingivitis more effectively as compared to Chlorhexidine alone. This combination along with the well-established effect of fluoride in the prevention of caries is an important contribution to dental public health.
