ABSTRACT

Aim: To evaluate and compare the effect of epoxy resin-based sealer and a pozzolan-based mineral trioxide aggregate (MTA) sealer on the fracture resistance of endodontically treated teeth.

Materials and methods: Thirty single-rooted mandibular premolars were decoronated to a standardized root length of 15 mm. ProTaper rotary files up to a master apical file size of F3 were used for cleaning and shaping the root canals followed by 2.5% sodium hypochlorite irrigation. The teeth were randomly divided into three groups (n = 10 each), and the obturation was completed using gutta-percha with Endoseal MTA (group I) and AH Plus (group II) as root canal sealers. Group III served as control (instrumented and unfilled). Each specimen was then subjected to fracture testing by using a universal testing machine at a crosshead speed of 1.0 mm/minute until fracture. The force required to fracture each specimen was recorded and the data were subjected to statistical analysis using one-way analysis of variance (ANOVA), followed by pairwise comparison using post hoc Games-Howell test (p < 0.05).

Results: The fracture resistance of groups I and II were significantly higher than those of group III. No significant difference in the fracture resistance was observed between group I (Endoseal MTA) and group II (AH Plus) groups.

Conclusion: It can be concluded that the new root canal sealer, Endoseal MTA, is able to reinforce the tooth against fracture as good as AH Plus.

Clinical significance: Endoseal MTA is a sealer for the reinforcement of endodontically treated teeth.

Keywords: AH Plus, Endodontically treated teeth, Fracture resistance, Sealer.

ABSTRACT

Aim: This study was carried out to compare the dentinal defects induced by single rotary file system, multiple rotary file system, and hand files.

Materials and methods: Sixty single-rooted premolars were selected based on predetermined criteria. They were divided into three groups: Group I (hand K files), group II (Hero Shaper), and group III (One Shape). Biomechanical preparation was carried out as per the manufacturer’s instructions. Each specimen was sectioned horizontally and divided into apical, middle, and coronal sections. These sections were visualized under stereomicroscope to evaluate the dentinal defects using predetermined criteria.

Results: Roots prepared with Hero Shaper showed more number of defects than One Shape, whereas in roots prepared with hand files lowest percentage of dentinal defects were present. There was statistically significant difference between the Hero Shaper group and the One Shape group (p < 0.05).

Conclusion: All rotary files induce defects in root dentin, whereas the hand instruments induce minimal defects.

Clinical significance: With single rotary file system, preparation time is reduced and it is easier for patients to accept the treatment. Moreover, the potential of root fracture is reduced.

Keywords: Dentinal defects, Hero Shaper, K files, One Shape.

ABSTRACT

Context: Tobacco is the foremost cause of preventable death and disease in the world today, and India is the second largest consumer of tobacco products in the world. The Cigarettes and Other Tobacco Products Act (COTPA) promulgated in 2003 by the Government of India, not only mandates ban on the sale of tobacco within a 100-yard radius around schools, but also provides guidelines for tobacco-free schools.

Aim: To determine if the provisions of the COTPA are being complied with, in Mangaluru, India.

Materials and methods: A cross-sectional study was conducted among 30 randomly selected schools in Mangaluru, India. Information was collected regarding sale of tobacco at vendor locations within 100-yard radius of these schools. An interview schedule was administered to the representative of the school, pertaining to the guidelines for tobacco-free schools.

Statistical analysis used: The data were coded and analyzed using the Statistical Package for Social Sciences (SPSS) version 11.5. The level of statistical significance was kept at p < 0.05.

Results: There were 48 shops located within 100-yard radius of the schools, out of which 46 (95.8%) sold single cigarettes but only one shop displayed surrogate advertisement. Among the 30 schools surveyed, only 3 (10%) displayed signages prohibiting smoking. Although the guidelines for tobacco-free schools explicitly state that all schools must have a copy of the COTPA, only 3 (10.0%) schools maintained a copy.

Conclusion: This study showed that there was a widespread violation of Section 6 of the COTPA 2003 in Mangaluru, India.

Keywords: Health policy, School health, Smoking, Tobacco.

ABSTRACT

Aim: This study was performed to evaluate the biocompatibility of pure titanium and Ti-6Al-4V metals coated with hydroxyapatite (HA) by plasma spray using different plasma gas atmospheres.

Materials and methods: The cell viabilities for each HA-coated sample in an atmosphere of argon, argon-hydrogen, nitrogen, and nitrogen-hydrogen were studied using MTT assay and platelet adhesion test.

Results: The mean cell viabilities by MTT [3-(4,5-dimethylthiazol- 2-yl)-2,5-diphenyltetrazolium bromide] assay of samples coated with HA in argon-hydrogen plasma atmosphere showed maximum cell viability at different time intervals compared with other coating atmospheres of argon-hydrogen, nitrogen, and nitrogen-hydrogen. A statistically significant value of cell viability (p < 0.001) was observed between and within the groups of argon, argon-hydrogen, nitrogen, and nitrogen-hydrogen plasma gas atmosphere. The platelet adhesion study showed agglomerates of platelet cells in some isolated regions of HA for all atmospheres.

Significance: The results obtained in this study can serve as a guide for the development of new Ti-based HA-coated implants in different plasma gas atmospheres.

Keywords: Cytocompatibility, Hydroxyapatite, MTT assay, Plasma coating, Platelet adhesion, Titanium, Ti-6Al-4V.

ABSTRACT

Introduction: Wakefulness about periodontal disease as of today is more than ever before. In spite of advancements in periodontal therapy, limitations do occur. Aggressive periodontitis being the most intricate as the etiopathogenesis is not clearly understood. Effective management of the disease is challenging during the advanced stages of the disease, and with the current therapeutic choices, it seems to be rather incomplete. Coping the patient to the situation is perhaps the least acknowledged and the most undervalued aspect in generalized aggressive periodontitis. As depression/stress influences the immune system and also alters the behavioral habits, it is extremely important to psychologically prepare the patient. Referral to appropriate professional for assistance and counselling should be included in the protocol for periodontal management. Adjustment, adaptation, and confrontation strategies need to be overlooked when preparing the patient. The quality of dentist-patient communication is a key determining factor in patient satisfaction, participation, and compliance with therapeutic planning. This paper aims to think through ways in which communication and incorporation of counselling as part of treatment protocol could improve the experience for the patient and allow better treatment by the team. Henceforth, psychotherapy promotes active participation of the patient rather than a passive receiver of the therapy.

Keywords: Aggressive periodontitis, Coping, Depression, Psychotherapy, Stress, Tooth loss.

ABSTRACT

Objectives: To evaluate the effects of number of bleaching sessions on fracture resistance and dentin microhardness in endodontically treated teeth using 15% hydrogen peroxide with titanium dioxide nanoparticles (15HPTiO2) associated to light emitting diode (LED)-laser system.

Materials and methods: Forty human incisors were endodontically treated and divided according to the number of bleaching sessions (n = 10, each group): G1 - no treatment G2 - one; G3 - two; and G4 - three sessions. The 15HPTiO2 was applied within the pulp chamber and on the buccal surface, then photoactivated using LED-laser. All experimental specimens were restored with ionomer glass cement between each session and in the final treatment. Specimens were then subjected to the fracture resistance test (kN), using an electromechanical machine. To the dentin microhardness evaluation, 40 crown extracted endodontically treated human teeth were longitudinally sectioned, divided into groups as previously described (n = 10), and submitted to similar bleaching protocol. Dentin microhardness was evaluated before and after the final dental bleaching session in each group using Knoop indentator. Data were analyzed by analysis of variance (ANOVA) and Tukey tests (p = 0.05).

Results: The fracture resistance values were similar among all groups (p > 0.05). The number of dental bleaching sessions had a negative influence on the microhardness dentin, because G4 > G3 > G2 > G1 (p < 0.05).

Conclusion: The number of bleaching sessions using 15% hydrogen peroxide with titanium dioxide nanoparticles associated to LED-laser system had no influence on the fracture resistance of the endodontically treated teeth crowns, but promoted a reduction in dentin microhardness.

ABSTRACT

Introduction: Radiation exposure encountered in dentistry is minimal; however, their harmful effects cannot be ruled out. Though there are several guidelines established to minimize exposure to X-rays in dentistry, earlier studies have reported that practitioners are not entirely compliant with the same. There is, therefore, a definite need to identify factors that influence compliance with radiation protection practices among general dental practitioners (GDPs).

Objective: The objective is to assess various factors influencing radiation protection practices among Indian GDPs. Materials and methods: A cross-sectional study design using a pretested, self-administered, structured questionnaire comprising of 37 items was employed in the present study. Information pertaining to demographics and radiation protection practices among GDPs was collected.

Results: A total of 66.7 and 49.4% did not follow position and distance rule respectively; overall, 88.5 and 94.3% did not use lead apron and thyroid collar respectively, for their patients. It was observed that 60.9% did not adjust exposure parameters according to tooth position; a total of 94.2% did not use personal dosimeters, while 63.2% disposed radiographic waste in common drain. Correlation analysis revealed significant association of awareness about governing bodies with educational course, distance rule with years of practice, personal dosimeter usage with gender, and other patients’ exposure to radiation with type of practice of the participants (p < 0.05).

Conclusion: The present study revealed poor radiation protection practices among GDPs. Low compliance with personnel- and patient-related protection measures was observed. A majority of the respondents were not familiar with radiation protection guidelines. Correlation analysis revealed important demographics that were influencing radiation protection practices among the respondents. The present study highlights crucial policy implications to ensure greater compliance with appropriate radiation protection guidelines among GDPs in India.

ABSTRACT

Aim: This study aims to evaluate the impact of soft skills’ formal assessment on the students’ interpersonal competency as evaluated by their own patients.

Materials and methods: A validated eight-item questionnaire with a 5-point Likert rating scale addressing relevant soft skills and rated by patients was used for two different cohorts of final year dental undergraduate students at the Universiti Kebangsaan Malaysia, Kuala Lumpur, Malaysia. The first cohort (class of 2009) did not receive a formal daily assessment during their clinical work, while the second batch (class of 2011) did. The daily assessment was used as a formative evaluation and included aspects of professionalism, patient empathy and education, organization of work area, and time management.

Results: For all the eight items in the questionnaire, more than 97% (total = 340) of the patients responded positively for both batches (2009 and 2011) of dental students. As for the scores related to specific items, there was improvement in the proportions of patients who were satisfied with all the items for the batch of students who had the formal assessment for their clinical work. These improvements, however, did not demonstrate any statistical significance (p > 0.05).

Conclusion: Patients were equally satisfied with the soft skills among two groups of final year dental students during clinical encounters. The formal assessment of soft skills did not have any impact on the measured outcomes.

Clinical significance: Soft skills are a learning experience for every dental student, which is useful in personal and professional life. An increase in health service and competitive dental practices emphasizes the need for soft skills to understand the dynamics of workplace and use of soft skills.

Keywords: Competency, Dental students, Patients’ assessment, Soft skills.

ABSTRACT

Introduction: Effective teaching is critical for student learning, especially in professional field, such as dentistry. To cope with the dynamic state of society, the changing pattern of diseases, a clear understanding of the links between basic sciences, technology, and health care systems are crucial. Future health care provider’s education system should encourage the development of learning characteristics, such as critical thinking and problem-solving. Problem-based learning (PBL) is one such method.

Aims and objectives: To evaluate the efficacy of PBL vs lecture method of teaching among the final-year dental undergraduates.

Materials and methods: A comparative study with 38 finalyear dental students, 19 students in PBL and 19 students in lecture groups were undertaken. The PBL group was further divided into three smaller groups. Both the groups were given a topic from the undergraduate curriculum of Public Health Dentistry prescribed by Dental Council India (DCI) and were assessed for their academic performances through an internal assessment examination.

Results: Both the groups consisted of higher number of females. Mean marks obtained by PBL group was 6.63 ± 1.80, which was significantly higher as compared with the lecture group which was 4.84 ± 1.17 (p = 0.001**).

Conclusion: Students in PBL group showed better academic performance as compared with students in the lecture group.
