ABSTRACT
AIM: The purpose of this prospective split-mouth, randomised clinical trial was to assess the clinical and radiographic success rate of pulpotomy in primary molars using calcium-enriched mixture (CEM) cement or placement of zinc oxide eugenol after electrosurgery (ES/ZOE). METHODS: Pulpotomy was performed for 102 primary second molars in 51 children aged between 4 and 6 years. Considering a split-mouth design, for each patient the right and left second primary molars randomly underwent pulpotomy using CEM cement or ES/ZOE. All teeth were restored using preformed metal crowns. Following pulpotomy procedure, teeth were blindly evaluated for clinical and radiographic success after 6, 12 and 24 months. McNemar test and SPSS 16 software were used for the statistical analysis. RESULTS: After 24 months, clinical success rates were 100% in both groups, however, radiographic success rates of ES/ZOE and CEM were calculated as 95.2 and 90%, respectively, with no significant difference (p = 0.625). The most common radiographic sign of failure was internal resorption. CONCLUSION: The results of this investigation show that the treatment success rate with CEM cement was similar to the electrosurgical pulpotomy.

BACKGROUND: Dental unit waterline system is considered potential source for contamination with Legionella species. The aim of this study was to determine if contamination of a dental unit water line system by Legionella pneumophila serogroup1 in the Mashhad School of Dentistry occurred in 2009. METHODS: A total of 52 dental units were selected from all clinical departments of the Mashhad School of Dentistry. Samples of water were collected from outlets of water/air spray, high-speed dental hand pieces and water cup fillers. Samples were tested via the ELISA method. RESULTS: At the beginning of the work day, a total of 36.1 percent of dental units were contaminated by Legionella pneumophila serogroup 1. CONCLUSION: Infection control of the dental unit water line system regarding legionella in the Mashhad School of Dentistry is a challenge and engineering controls should be used in contaminated clinics.
