The Antibacterial Effect of Diode Laser versus Sodium Hypochlorite in Root Canals of Primary Anterior Teeth Inoculated with Enterococcus Faecalis

Abstract

1.1 Introduction Recovered micro-organisms from the infected root canals has described by Miller since 1890 [1]. Starting from that time, the microbiological basis of both endodontic disease and treatment failure has become firmly established [2]. The teeth with infected root canals, particularly those in which infection has reached the periradicular tissues are a common problem in primary dentition [3]. Early loss of primary teeth may cause a number of problems in the permanent dentition. Examples are: space loss for the successor, ectopic eruption or drifting of erupted teeth, disturbance of eruption sequence and development of aberrant habits such as tongue thrusting; all may lead to malocclusion in addition to impairment of function and alterations in speech [4, 5]. Thus it is important that primary dentition should be maintained in the dental arch, provided it can be restored to function and remain free from the disease.
