Abstract: Aim: The aim was to compare the efficacy of two local drug delivery systems, one containing chlorhexidine and the other containing tetracycline hydrochloride as adjuncts to mechanotherapy in the treatment of a chronic periodontitis case.
Background: Recent development of science and technology has revolutionized the basic outlook and approach to the problems of periodontal disease. Although mechanical therapy (scaling and root planing) are the basic treatment modality for periodontal disease, mechanical treatment is limited by physical impediments and biochemical considerations. Hence a thorough understanding of the etiopathogenesis of periodontal disease has provided the clinicians and researchers a number of diagnostic tools and techniques that has widened the treatment options. A promising treatment modality would be the use of antimicrobial agents as an adjunct to overcome limitations of mechanotherapy. Modern concepts of treating inflammatory periodontal disease aim at changes in the subgingival ecosystems within the periodontal pockets to alter the complex microbial community into a microbiota compatible with good periodontal health. Systemic antimicrobial therapy, although effective, involves a relatively high dose with repeated intakes over a prolonged period of time to achieve the required inhibitory concentrations in the sulcular fluid. The adjunctive use of local drug delivery may provide a beneficial response, especially in specific areas where conventional forms of therapy might fail.
Conclusion: In conjunction with scaling and root planning, the adjunctive use of local delivery of drugs like chlorhexidine and tetracycline may enhance the results in isolated periodontal pocket sites that do not respond to conventional therapy.
