Abstract :

The aim of this study was to evaluate the antimicrobial effect of 10% water extraction of Salvadora persica (Miswak) when used clinically as an endodontic irrigant. Twenty four uniradicular teeth with necrotic pulps were chosen. The patients were divided randomly into 2 groups: Experimental group, in which water extract of Salvadora persica (10%) was used as a root canal irrigant; and control group, in which distilled water was used as a root canal irrigant.
Bacteriological samples were obtained from the canal at the step of working length determination (before the canal was subjected to instrumentation and irrigation procedures), and at the end of the biomechanical instrumentation procedures by using a sterile K–file. The file was separated from the handle using a sterile wire cutter, and the severed portion was placed in a sterile screw–capped vial containing 5 ml of thioglycollate broth as a transport media. A 0.1 ml of thioglycollate broth was inoculated on each of two brain–heart infusion agar plates: One plate was incubated under aerobic conditions, and the other was incubated under anaerobic conditions using anaerobic jar and gas pack anaerobic system. Both plates were incubated at 37 ºC for 24 hours; then, the number of bacterial colonies was counted. The results revealed that 10% water extraction of Salvadora persica is an effective antimicrobial agent when utilized clinically as an irrigant in the endodontic treatment of teeth with necrotic pulps.

Abstract :

To investigate the incidence of handpiece asepsis in general dental practice in Mosul City and to evaluate the problems associated with routine handpiece sterilization which are commonly needed by those practitioners.
Materials and Methods
A questionnaire was designed to collect the information about handpiece asepsis techniques performed by dentists. One hundred twenty dentists in Mosul City were randomly selected and the data were analyzed.
About 55.8% of the respondents know about the importance of handpiece sterilization, but no one do ideal sterilization between each patient due to absence of sufficient number of handpiece and lack of autoclave system in clinics. No one disinfect the handpiece scientifically; 59.38% smear the handpiece between each patient by one of the antiseptic solutions.
Handpiece asepsis in Mosul dental clinics is poor. Most of dentists depend on disinfection by disinfectant solution to prevent cross infection by handpieces. Most dentists, because of their poor equipment in both private and national clinics, cannot sterilize handpieces after each patient

Abstract :

The aim of this study was to evaluate the diagnosis accuracy of approximal carries by visual, fiber optic transillumination (FOTI) and bitewing radiograph examination performed by two observers. A total of (372) unrestored posterior pertinent approximal surfaces of (186) patients were examined in Conservative Department during final clinical examination for under-graduate students, using the diagnostic methods under the study. The results were compared with the validation. The accuracy of each diagnostic method for identification of cavitated carious lesions was expressed by the terms: sensitivity, specificity and predictive values. The sensitivities for identification of cavitated lesions using visual examination about (0.28), for FOTI and radiography were (0.04) and (0.59) respectively. The specificity collectively was about (0.9). On the basis of these results, it was concluded that FOTI was the least reliable of the diagnostic methods tested. Also, it was found that visual examination should precede theradiographical examination for identification of cavitated carious lesions.
