Brief Summary

Periodontitis, a bacterial dental biofilm based infectious disease, is a chronic inflammatory disease of the periodontium which results in irreversible destruction of supporting structures of the teeth such as periodontal ligaments, connective tissues, cementum and alveolar bone. More than 700 species of bacteria are estimated to be found in the sub-gingival dental biofilm in which periodontopathogens are found to be responsible in initiating periodontal disease. Chronic periodontitis, although termed as 'chronic', starts as an acute inflammation. Low levels of bacteremia and endotoxins provides a stimulus for the systemic inflammatory response. In periodontitis, the interaction of lipopolysaccharide (LPS) from gram-negative bacteria with host cells initiates the secretion of cytokines and the expression of cell adhesion molecules in gingival tissue which leads to loss of alveolar bone and connective tissues supporting the teeth. In the management of chronic periodontitis, non surgical periodontal therapy (NSPT) which includes oral hygiene instruction (OHI), scaling and root planing, is administered to improve clinical parameters as well as controlling the bacterial count responsible in initiating the disease and the resultant inflammatory response. Success of the treatment can be analyzed when the clinical parameters, counts of the microbes is reduced and inflammatory response is controlled. Studies which have evaluated the microbiological and immunological response following NSPT clearly demonstrates an improvement in clinical parameters, reduction in inflammatory mediators present as well as a decrease in microbial count. OHI which includes tooth brushing and inter-dental cleaning is found beneficial in removing microbial plaque, thus, preventing periodontal diseases such as gingivitis and periodontitis. Studies have evaluated the role of OHI on clinical and immunological parameters and microbiological profiles of periodontal maintenance subjects, while none of them evaluated its role alone in the management of chronic periodontitis subjects. Therefore, the purpose of the following investigation was to compare the changes in the clinical parameters, inflammatory mediators as well as level and frequency of detection of periodontopathogens that take place after 3-months of NSPT versus OHI and to evaluate if clinical parameters have an effect on these inflammatory mediators and microbiological changes.

Study Arms (2)

Nonsurgical periodontal therapy

EXPERIMENTAL

Nonsurgical periodontal therapy was given to all patients at baseline

Procedure: Nonsurgical periodontal therapy

Oral hygiene instructions

ACTIVE COMPARATOR

Oral hygiene instructions were given to all patients at baseline

Procedure: Nonsurgical periodontal therapyProcedure: Oral hygiene instructions

Interventions

All patients were instructed in oral hygiene methods using a soft bristled toothbrush, a compact-tuft toothbrush, interdental brushes and dental floss utilizing the modified Bass technique. Full mouth debridement, which consisted of scaling and root planing, was done in a single visit for all subjects using an ultrasonic scaler and gracey curettes. Additionally, all patients were given a 0.12% Chlorhexidine mouthrinse (Hexipro®). They were instructed to rinse three times a day using 15ml each time for a period of 14 days commencing immediately after completion of full mouth debridement. Thereafter at each recall visit, all participants were re-motivated and professional prophylaxis was performed.
