AIM Root debridement by scaling and root planing may not completely remove contaminated cementum particularly in more apical areas. The smear layer formed during root planing inhibits cell migration and attachment leading to impaired marginal periodontal healing. The present study was done to compare the morphological effects of root surface demineralization using citric acid and EDTA as root-c...

Aim and objective: This study was conducted to evaluate and compare the effectiveness of various root planing instruments, namely the curette, standard smooth ultrasonic tip and diamond coated ultrasonic tip under conditions of nonsurgical root debridement. Materials and methods: A total of 20 incisors from 14 patients, with a pocket depth of 5 to 10 mm, indicated for extraction were selected f...

Complete debridement and thorough disinfection of infected root canals are considered mandatory for the success of root canal treatment. However, canal preparation and irrigation are not always effective in eliminating total microflora from the root canal system. Traditionally, calcium hydroxide has proven to be an excellent intracanal medicament for infected root canals. However, it is known t...

Chemomechanical debridement is an integral part in endodontics. Mechanical debridement results in the formation of smear layer on root canal surfaces whereas chemical debridment results in removal of smear layer resulting higher success of root canal treatment. This present study evaluates the chelating and antimicrobial ability of phytic acid alone and in combination with different irrigating ...

BACKGROUND Long term successful root canal treatment requires effective debridement and disinfection of root canal system. Persistent periradicular lesions are usually associated with Enterococccus faecalis. Prompt research for natural alternatives for irrigation is mainly due to the constant increase in antibiotic resistant strains and side effects caused by synthetic drugs. Sodium hypochlorit...

Successful root canal treatment is based on diagnosis, treatment planning, knowledge of tooth anatomy, and the traditional concepts of debridement, sterilization, and obturation. Several obturation techniques are available for root canal treatment. The choice depends on the canal anatomy and the unique objectives of treatment in each case. The two basic obturation procedures are lateral condens...

UNLABELLED Periodontal debridement (PD) remains a gold standard for the treatment of inflammatory periodontitis. BACKGROUND/PURPOSE The evidence base regarding the causal relationship between oral biofilm and the host inflammatory response to the etiology of periodontal disease has substantially increased over the years. What has not changed significantly during that time is the conservative ...

A fifty eight year old man with Marfan's syndrome and an aortic composite graft with a Björk-Shiley mechanical prosthesis presented with a large aortic root abscess caused by Staphylococcus aureus endocarditis. Despite extensive surgical debridement and implantation of an aortic homograft as a composite graft, early postoperative transoesophageal echocardiography continued to demonstrate a larg...

Biofilm and calculus removal are very important components of periodontal therapy, and a variety of instruments may be used for debridement purposes. In recent years, the application range of sonic and ultra sonic scalers in such debridement procedures has been extended to the subgingival area as slim instrument tips allowing good access to the root surfaces have been developed. Treatment using...

Files of Greater Taper (GT) are rotary nickel-titanium files of three tapers (0.06, 0.08, 0.10) with file tips of sizes 20, 30, and 40. The purpose of this study was to compare in an in situ model the efficacy of root canal debridement in the apical 3 mm when instrumenting to a GT size 20 or a GT size 40 at working length. Twenty matched human cadaver teeth with 32 canals were decoronated at th...
