    The objectives of this study were to assess the practice of molar root canal treatment (RCT) among general dental practitioners (GDPs), confidence level of GDPs in performing molar RCT and to identify factors that influence their confidence in managing molar RCI. One hundred questionnaires were distributed to GDPs in Kuala Lumpur and Selangor. Fifty questionnaires were delivered by mail and the remaining fifty were hand-delivered. All data was coded and verified. Fiftysix OOPs rcsponded to the questionnaires. Only fortyfive questionnaires were accepted (n=45) as eleven OOPs had never performed molar RCI. Most of the OOPs followed the standard quality guidelines while performing molar RCT except for vitality testing (36.4%) and rubber dam usage (27.3%). In this study, 100% of the GDPs were confident in making diagnosis of perinidicular diseases and 95.4% were confident in performing molar RCT from history taking until obturation. Patients' tolerance and availability of instruments and materials (97.7%) were two factors that most influence the GDPs' confidence level. The. least influcncing factor was undergraduate training (78.1 %). Attending seminars and lectures on endodontic, large number of molar teeth treated for ReT, patLents' affordability to pay for RCT and postgraduate training also influencc GDPs' confidence to a certain degree. From this study, it can be concluded that majority of OOPs complied standard quality guidelines except for vitality testing and rubber dam usage. Most of them were confident in performing molar RCT and were greatly influenced by the availability or"instruments and materials in their clinic and patients' tolerance in receiving molar RCI.

    The aim of the study was to determine the frequency, size and location of apical and lateral foramina on anterior teeth. A total of 100 anterior teeth consisting of maxillary and mandibular incisors and canines were fixed in 10% formalin. Periodontal tissue remnants were mechanically removed and teeth were stained in 2% aqueous silver nitrate. The teeth were dried and examined using a Leica MZ 7.5 zoom stereomicroscope. The size of apical and lateral foramina and their distance from the anatomical apex of the tooth were measured directly using a calibrated eyepiece scale. Accessory foramina more than 1.8 mm from the apex were regarded as lateral foramina. Eighteen percent of teeth possessed more than one apical foramen. Seven teeth (three maxillary centrals, three maxillary canines, one mandibular lateral) had 11 lateral foramina each. The mean diameter of the lateral foramina was 0.14 mm (SD = 0.08) and their mean distance from the apex was 4.49 mm (SD = 2.63, range 1.9-10.5 mm). Multiple foramina were most common on maxillary canines and least common on maxillary laterals. The mean diameter of apical foramina for all teeth possessing a single foramen was 0.35 mm (SD = 0.10) and the mean apical foramen diameter for all teeth with multiple apical foramina was 0.22 mm (SD = 0.08). Most anterior teeth possess one apical foramen and no lateral foramina; about 20% possessed more than one apical foramen and about 10% possessed one or more lateral foramina. These findings should be considered when root-treating anterior teeth.

    BACKGROUND: The influence of scaler tip design on root surface roughness, tooth substance loss and patients' pain perception is investigated.

    METHODS: This article was divided into the following parts: Part 1 Surface roughness and substance loss: an in vitro study, which involves intact extracted teeth sectioned and treated using a piezoelectric ultrasonic device (PM200 EMS Piezon, Switzerland) with a conventional scaler tip (FS-407) and a Perio Slim (PS) scaler tip (Perio Slim DS-016A). All sectioned samples for tooth surface roughness (n = 20) and tooth substance loss (n = 46) analyses were measured and compared using a 3D surface texture analyser and scanning electron microscope (SEM) respectively, at baseline and following scaling. Part 2 Pain Perception: a clinical study, which was a split mouth study design including 30 participants with gingivitis and/or mild chronic periodontitis; treated with supra-gingival scaling from teeth #13 to #23. Subjects were randomised to group A or group B. Group A was treated first with PS scaler tips, whereas group B was treated first with conventional scaler tips. Pain perception was recorded using the visual analogue scale (VAS).

    RESULTS: In vitro study: both scaler tips caused significant reduction in root substance roughness after scaling (p  0.05) was observed. The PS scaler tip caused statistically significantly less root substance loss (p tooth was tooth substance loss compared to a wider scaler tip design. In the clinical study, less pain was observed compared than a wide (conventional) scaler tip design.
