Authors: Matsuki Y, Matsuura N, Ichinohe T Abstract Application of nitrous oxide during anesthesia causes an increase in tracheal tube cuff pressure over time. The purpose of this study was to investigate the effect of an increase in cuff pressure on 3 types of tube (the Portex, Mallinckrodt, and Parker) commonly used for nasotracheal intubation. A cylindrical vessel was used to simulate a trachea. Cuff pressure was set at 0 cmH2O (R0) or 20 cmH2O (R20) at room temperature, or at 20 cmH2O (H20), 40 cmH2O (H40), 60 cmH2O (H60), or 80 cmH2O (H80) in 38°C hot water and pressure applied for 30 min. The value obtained at R0 was used as a reference (100%) and the rate of change under each condition determined. No change was observed at R20 in any of the 3 groups. In 38°C hot water, int…

Tooth Loss in Problem-oriented, Irregular, and Regular Attenders at Dental Offices.
Authors: Yoshino K, Ito K, Kuroda M, Sugihara N Abstract The aim of this retrospective study was to compare number of teeth lost among regular attenders (RAs), irregular attenders (IRAs), and problem-oriented attenders (POAs) at dental offices over a 10-yr observation period. Information on tooth loss was obtained from general practitioners. Patients were divided into 3 groups based on appointment adherence. A total of 1,886 teeth were lost in 1,400 patients. The mean number of teeth lost in men was 2.2±2.6 per patient over 10 yr in POAs, 1.2±1.7 in IRAs, and 1.5±1.5 in RAs. This number was significantly lower in IRAs (p = 0.011) or RAs (p=0.012) than in POAs. When the dependent variable was defined as “a patient with at least 2 or more extracted teeth”, the independent variable…

Application of 17% EDTA Enhances Diffusion of (45)Ca-labeled OH(-) and Ca(2+) in Primary Tooth Root Canal.
Authors: Ximenes M, Cavalcanti Taguchi CM, Triches TC, Sartori N, Pereira Dias LA, de Araujo EB, Cardoso M Abstract Proper cleaning of the root canal is key to the success of endodontic treatment as it allows more effective diffusion of medication throughout the dentinal tubules. The aim of this in vitro study was to investigate the efficacy of 17% ethylenediaminetetraacetic acid (EDTA) in enhancing diffusion of hydroxyl (OH(-)) and calcium ions (Ca(2+)) throughout the root canal in primary teeth. The canals of 25 primary tooth roots were cleaned with endodontic files and 1% sodium hypochlorite. Three groups (G) were then established: GI, in which final irrigation was performed with 1% sodium hypochlorite; GII, in which 17% EDTA was used; and GIII, in which no irrigation was perfor…
