Abstract

The aim of this study is to evaluate the effect of type ofthe tooth and the placement site of electrode on electrical pulptesting of the anterior teeth. Twenty persons were participatedin this study. The six maxillary and mandibular anteriorteeth were checked to evaluate the response threshold to electricalpulp testing; each tooth was examined at four placementsites on its labial surface, which are the incisal edge, incisalthird, middle third and the cervical third.The results showed that the response threshold of themandibular anterior teeth was lower than that of the maxillaryanteriors. The canines may respond to the electrical stimulusin a highest threshold than the lateral incisors and the centralincisors which had the lowest response threshold. Also, thisstudy showed that the best placement site of electrode was inthe incisal edge of the tooth and the pulp tester reading wasincreased as the electrode moved toward the cervical regionof the tooth.

Abstract

The aim of this study was to evaluate clinically the intracoronal restorations among people in Sharkhan village. A sample of (180) persons was selected randomly for the study. The age range between 18-60 years old. A clinical examination was performed. The restorations were examined for different types of failures. A percentages of failures are observed with expose margins (37%), recurrent caries (27%), over - hang fillings (18%), restoration fractures (11%), open contacts (7%), over filling (7%), corrosion (6%), color failure for anterior restoration (4%) and finally fracture of restored teeth (3%).

Abstract

Aims :evaluate the effect of abutment angulation on fracture strength of pre-fabricated zircon implant abutment supported CADCAM zircon crown. Material and methods: Ten analog with 3.75×14mm were placed into resin blocks divided in to 2 groups: group A (n=5) parallel to long axis and group B (n= 5) fixed at angulation (17°) to long axis. Then ten abutments were tightened to 25 N/cm2. Ten full anatomic zircon (CAD/CAM) crowns constructed as upper right central incisor: 5 on each group. After luting all crowns with dual cure resin-based luting, all samples passed to artificial aging using thermocycling machine, 500 cycles at (5 to 55 C°±2) degree. Then the load was applied by universal testing machine at 30 degree to the long axis until fracture occurred. Results: Statistical analysis showed that the implant abutment angulations significantly (p < 0.05) reduced the fracture resistance of zircon implant abutment. Conclusions: Within the limitation of this in vitro study it may be concluded that: the fracture strength of zircon implant abutment supported CADCAM zircon crown is significantly reduced in respect to the angulation fromstraight to angulated (17°) zircon abutment.

Abstract

Aims: To investigate the incidence of handpiece asepsis in general dental practice in Mosul City and toevaluate the problems associated with routine handpiece sterilization which are commonly needed bythose practitioners. Materials and Methods: A questionnaire was designed to collect the informationabout handpiece asepsis techniques performed by dentists. One hundred twenty dentists in Mosul Citywere randomly selected and the data were analyzed. Results: About 55.8% of the respondents knowabout the importance of handpiece sterilization, but no one do ideal sterilization between each patientdue to absence of sufficient number of handpiece and lack of autoclave system in clinics. No onedisinfect the handpiece scientifically; 59.38% smear the handpiece between each patient by one of theantiseptic solutions. Conclusion: Handpiece asepsis in Mosul dental clinics is poor. Most of dentistsdepend 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 aftereach patient.

Abstract

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

Abstract

A survey of (213) subjects from Sharkhan village near Mosul city was involved by questioner to evaluate the methods used to maintain the oral and dental health and involved also a clinical examination for the sample to evaluate the incidence of dental carries according to G.V Black classification. The study showed that only (1.66%) of Sample were visit the dentist regularly, (53.33%) were visit the dentist on need only and (45.01%) never visit the dentist. A bout the methods used to maintain the oral hygiene, the questioner showed that (61.92%) of sample never used tooth brush, (15%) used the brush regularly, while (23.08%) brushing there teeth intermittently. The questionnaire explained that (28.43%) using mouth wash, (4.68%) using dental floss, (109) using picks and only (3.84%) using wood stick (Miswak). The examination showed that tooth (23.27%) of sample having (1-3) carious teeth, (34.06%) having (46) carious teeth and this mean that (3.16% 0 of sample were caries free. The pits and fissures caries was the type of highest percentage (67.06%) followed by proximal caries (22.8%) and other types of classification were less.

Abstract

The aims of this study are to determine the prevalence of dental discoloration in the rural area and to identify, if there is any variation between sex and age group in a sample of (114) subjects aged (5-44)years. The sample was divided into four age group (5-14),(15-24),(25-34) and (35-44) years. The results revealed high percentage of teeth discoloration in all age groups & it was particularly due to natural or acquired cause and there were no differences between the age groups or sex. Also, the result of this research showed that about (82%) of the total sample are with discoloration defect in their teeth.
