Chlorhexidine varnishes prevent gingivitis in adolescents

Area of Science:

• Pediatric Dentistry
• Periodontology
• Antimicrobial Therapy

Background:

• Gingivitis is a prevalent periodontal disease in children and adolescents.
• Chlorhexidine is a cationic antimicrobial agent that inhibits plaque accumulation.
• Professional application of chlorhexidine varnish may improve gingival health.

Purpose of the Study:

• To evaluate the efficacy of a chlorhexidine varnish in improving the gingival status of adolescents.
• To assess the impact of professional chlorhexidine varnish application on adolescent gingival health.

Main Methods:

• Adolescents aged 10-15 were randomized into control (n=53) and treatment (n=57) groups.
• Treatment group received a 10% chlorhexidine varnish application at baseline, one week, and three months.
• Gingival Index (GI) was blindly assessed by a calibrated examiner over a six-month period.

Main Results:

• The treatment group showed a significant reduction in sites with moderate to severe gingivitis (GI scores 2 or 3) over six months.
• Average percentage of sites with GI scores 2 or 3 decreased from 3.68% at baseline to 0.16% at six months in the treatment group.
• The control group showed minimal changes in GI scores over the same period, with values ranging from 2.11% to 1.59%.

Conclusions:

• Professional application of chlorhexidine varnish significantly improves gingival health in adolescents.
• Chlorhexidine varnish is an effective intervention for managing gingivitis in pediatric and adolescent populations.
• The study demonstrates a sustained positive effect of chlorhexidine varnish on gingival status over six months.
