Evolution of CPITN Index in Relation to Chlorhexidine Mouthwash Use in Patients with Deflective Occlusal Contacts

CHX mouthwash significantly improved periodontal parameters in patients with occlusal trauma during the first three months of use. However, improvements plateaued after this period, highlighting the short-term benefits and limitations of CHX. These findings support the adjunctive role of CHX in managing periodontal disease associated with occlusal trauma but reinforce the necessity of mechanical occlusal correction for long-term stability. The CPITN index provides moderate clinical utility compared with full-mouth clinical periodontal measurements.
