Efficiency of the chronic apical periodontitis treatment while using depotphoresis

Abstract

Topicality. Caries complications are a major cause of early loss of teeth. The effectiveness of conservative treatment of apical periodontitis is quite low. The problem is rational additions to root canal instrumentation and appropriate medications to suppress conditionally pathogenic root canal microflora. The solution is to improve treatment and implementation in the dental practice. The research shows that a thorough treatment of root canal system reduces the level of microbial contamination on average by 40 %. To improve the quality of antibacterial treatment of root canals we used the method of depotphoresis by Knappvost. The success of this method reaches 80-95 %, which is particularly valuable in cases of bad walk-through of root canals. Thus, the problem of improving the efficiency of treatment of chronic apical periodontitis in patients with predominance of the parasympathetic nervous system is relevant and necessary to further explore the possibility of optimal use to this aim depotphoresis.Aim: To determine the effectiveness of depotphoresis copper-calcium hydroxide in the treatment of chronic apical periodontitis in patients with predominance of the parasympathetic nervous system in the next term observations.Material and methods. Clinical studies were conducted on a group of 60 patients with apical chronic periodontitis and predominance of the parasympathetic nervous system. The treatment of patients with chronic apical periodontitis was carried out according to treatment protocols approved by the Ministry of Health of Ukraine (2005). Patients with chronic apical periodontitis were administered depotphoresis by Knappvost. The root-canals were obdurate with permanent composite restoration. Efficacy of treatment was assessed on the basis of clinical and radiological data immediately after the treatment, and the results came a year later.Results. Using this method we have treated 60 teeth with chronic apical periodontitis. In most cases, 56 (93,33 %) teeth we did not find any exacerbation of process after the treatment. X-ray examination indicated the tendency to restore bone in periapical areas in 57 patients (95,0 %). Comparison of destruction areas before treatment and after treatment showed its decrease in 53 (83,33 %) patients.Conclusions. The results suggest high efficiency during the treatment of patients with predominance of the parasympathetic nervous system with chronic apical periodontitis using depotphoresis.
