Posterior Restorations

Background: The most common restorative materials used in dentistry are amalgam and composite. Amalgam is a controversial material owing to its mercury toxicity. With recent advances in the properties of composite materials, there has been a shift towards its use. Objectives: The aim of this study was to understand the perceptions of undergraduate dental students in a northern Saudi Arabian dental school about the choice of restorative materials for restoring posterior teeth. Methodology: The study included undergraduate students studying in 4th and 5th year dental program in College of Dentistry, Jouf University. A four-item questionnaire with 18 close-ended questions was developed by the investigators, which were hand delivered to all the students. Data analysis is presented through tables and descriptive methods. Results: A total of 98 (out of 131) undergraduate students participated in this study. Overall, the students reported a significantly strong influence of the type of restorative materials in relation to the cavity size and margin of the restorations along with the esthetics factor(p<0.05). There was slight influence on the student’s choice because of the instructor's influence, whereas the students felt they were knowledgeable and had appropriate training to use either amalgam or composite. The study also found that patient’s preference had a strong influence on choosing composite material. The students were mostly not influenced while choosing the material as far as the safety of it was concerned. However, the patient’s influence was slight when it came to the choice of the material. A significant difference was noted among the students when it came to pregnancy-related safety concerns where the choice of material was not influenced by either amalgam or composite (p=.002). Conclusion: The undergraduate dental students at College of Dentistry, Jouf University are comfortable in using both amalgam and composite as a posterior restorative material. They are knowledgeable about both the materials and are adequately trained to use either one.

Objective: The objective of this study was to assess the knowledge, awareness, and practices of dental students regarding biomedical waste (BMW)management.Methods: A self-administered structured questionnaire consisting of 16 questions on knowledge, awareness, and practices about BMW managementwas distributed among 100 students randomly belonging to 3rd year, final year and intern students of Saveetha Dental College, Saveetha University,Chennai. The data extracted were tabulated, statistically analyzed using SPSS version 20.0 and results obtained. The data were analyzed using ANOVAtest (all the results are calculated at 1% level of significance) and Post-hoc test.Results: Overall, 67% respondents were aware of the existing BMW management policy systems in India. 62% of students were aware about thecorrect color coding management system for hospital waste management that prevails in India. 86% of students knew about the dental wastecategories of materials used in dentistry. There was a statistically significant difference of knowledge levels among the 3rd year, final year students andthe interns. 100% practice discarding sharps in the puncture-proof containers. Only 27% of the respondents discarded the extracted tooth in a properway. Only 51% of them have attended previous training programs on dental waste management. There was also a statistically significant difference ofBMW disposal practices among the three groups.Conclusion: The majority of dental students in our study have good level of knowledge and awareness regarding BMW management in dental clinics.However, their practice toward BMW disposal was poor. Hence, the knowledge acquired must be put into practice. Intern students have the highestlevel of knowledge and practices toward dental waste disposal when compared to final year and 3rd year students. Hence, these findings imply thatproper training, continuing education programs, and short-term courses about BMW management, and infection control procedures are requiredto motivate the dental students and dental auxiliaries. The importance of training regarding BMW management must be emphasized as the lack ofproper and complete knowledge about BMW management impacts practices of appropriate waste disposal.

Objective: To determine the differences of self-perception of halitosis and oral hygiene practices among the medical and dental undergraduate students. Methodology: A cross-sectional study conducted over duration of 9 months amongst the medical and dental undergraduate students of Bahria University Medical and Dental College. The questionnaires were distributed to 298 students. Questionnaire employed for this study was adopted and modified from the study conducted by Khalid Almas et al. Descriptive statistics were checked by means of percentages and frequency for all variables. Chi-square test was applied to check significant difference among the responses given by the medical and dental undergraduate students. Results: The response rate for the survey was about 85%. 55% of dental and 17 % of medical students were able to smell their breath. About having examination by dentist about 73% of medical students agreed as compared to 53% of dental students. Both medical and dental students preferred having examination done by the dentist. For management of halitosis, dentist was preferred by 62% of the dental students, while 97% of the medical students did not agree. 62% of the dental students preferred using traditional medications, while 82% of the medical students preferred using self-medications for treatment. Conclusion: The results suggest that there is not a high level of agreement among dental and medical students concerning the detection and management of halitosis. Although large percent of the respondents claimed to be aware of dentistry, our findings revealed low level of knowledge and attitude to Dentistry by the medical undergraduate students. Efforts should be made towards closing this knowledge gap to attain effective oral health.

Aim: The aim of this study is to evaluate the effects of whitening toothpaste applications on the color stability of different tooth-colored restorative materials (Fuji IX, GC Fuji II LC, Equia Forte, and Kerr Point 4)  Methodology: Standardized fourty disc-shaped specimens were prepared from esthetic restorative materials and polished. The baseline color values of each specimen were then measured using a spectrophotometer, according to the Commission Internationale de l'Eclairage L*, a*, and b* (CIELAB) color scale. Ten specimens from each group were then immersed in two different beverages (cherry juice and coke) for seven days. After immersion, the color value of each specimen was re-measured. Each sample was brushed with whitening toothpaste for 30 seconds using an electric toothbrush. The samples were kept in distilled water at room temperature and brushing continued twice a day for seven days. The color change value, Delta E (ΔE), was calculated. Data were analyzed by two-way ANOVA and post hoc Tukey's test. Results: When the results were evaluated, after the colored samples had been brushed with whitening toothpaste, a difference was found between the Delta E values according to the materials used (p<0.001), but no difference was found in relation to the beverages (p>0.001). When the values of the color changes were evaluated after the first brushing with whitening toothpaste and before the specimens were colored with drinks, a difference was observed in the Fuji II cola, Fuji II cherry, and Equia Forte cola groups (p<0.05). When the values of the color changes were evaluated for specimens in which brushing had been done twice a day for seven days with whitening toothpaste and before they were colored with drinks, a significant difference was observed in the Fuji II cherry and Equia Forte cola groups (p<0.05). Conclusion: Using Signal White Now whitening toothpaste for 2 min 2 times a day for seven days caused significant changes in the color of the restorative materials. The color change is dependent upon the type of restorative material that is used.   How to cite this article: Kahvecioğlu F, Çoban E, Ülker HE.

The aim of the present study was to assess the quality of canal obturation performed by undergraduate denal students at Saveetha Dental College and Hospitals, Chennai. Records of 200 endodontically treated teeth from patients who were visited by undergraduate students between month of November 2014 to May 2015. Periapical radiographs of all treated teeth were assessed in terms of canal obturation quality (adequate density and length). Forty-five percent of teeth fulfilled the criteria of an acceptable root canal obturation. Adequate length and density of root filling was found in 89% and 34% of teeth, respectively. There was a significant difference between maxillary and mandibular teeth regarding the length of root canal obturation. A significant difference was observed between molars and other tooth types. The frequency of root canals with an acceptable filling was significantly greater in the anterior teeth compared to premolars or molars. The technical quality of root canal treatment performed by undergraduate dental students was found to be less than ideal.

This retrospective study evaluated the clinical performance and the reasons for failure of anterior and posterior composite restorations placed by undergraduate dental students over a 3-year period. All cavities were restored using Prime & Bond 2.1 and TPH (Dentsply), according to the manufacturer's indications. One hundred and two patients who had received composite restorations by third and forth year undergraduate students were recalled and examined to analyze the quality of the restorations. The restorations were evaluated using the modified USPHS system. Two hundred and fifty-six composite restorations, 170 in anterior teeth and 86 in posterior teeth, were evaluated. Eighty-five percent of the restorations were considered satisfactory after 3 years. Class II and class IV restorations presented the highest prevalence of failure. Loss of the restoration and deficient marginal adaptation were the main causes of failure. No restoration failed due to secondary caries. Most restorations placed by dental students were considered satisfactory after long-term evaluation. Failure was more prevalent in larger restorations and was not associated with secondary caries.

ABSTRACT Aim To evaluate and compare the microleakage of various restorative materials used as coronal barriers between endodontic appointments. Materials and methods Eighty extracted human permanent posterior teeth were prepared for standardized access cavities with dimensions of 4 × 4 × 4 mm. The teeth were then randomly divided into four groups; Kalzinol, Caviton, GC Fuji IX and GC Fuji II LC. After incubation, the samples were immersed in 2% methylene blue for 7 days. The depth of penetration was measured using a digital macroscope after longitudinal sectioning of each tooth. Kruskal-Wallis (p < 0.05) and multiple Mann-Whitney test with Bonferroni correction (p < 0.008) were used for data analysis. Results The degree of microleakage varied at the material/ tooth interface among the test materials, and the difference was statistically significant (p < 0.05). GC Fuji II LC group showed the least median microleakage value (0.8105 ± 0.305), followed by Caviton (1.1885 ± 0.396), GC Fuji IX (3.3985 ± 0.305) and Kalzinol (4.161 ± 0.853). Conclusion Within the limitations of this study, GC Fuji II LC exhibited the best marginal seal, and has the potential to be used as a suitable coronal barrier between endodontic appointments. Clinical significance Given the prime importance that dental practitioners should thoroughly restore any tooth with a suitable coronal barrier between endodontic appointments, this study shows that Fuji II LC has the ability to maintain a hermetic seal for 7 days.
