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

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.

Keywords: Dental bleaching, Dentin, Endodontics, Hydrogen peroxide, Lasers.

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

Gingival recession is one of the most common soft tissue problems, especially when it hinders the esthetics of a patient. Gingival recession can further lead to root caries, sensitivity, and difficulty in plaque control. Moreover, exposed roots are prone to abrasion and erosion. Periodontal plastic surgery is one of the emerging fields, which helps to meet such soft tissue problems. Currently, a variety of techniques are being used for root coverage, like pedicle grafts, coronally advanced flap, free mucosal graft, epithelial connective tissue graft, guided tissue regeneration, and acellular dermal matrix. This article highlights a case that was successfully managed by double papilla graft technique in combination with amnion membrane for root coverage of Miller class II recession defect in the mandibular canine region. In this technique, the soft tissues adjacent to the recession area were positioned over the recession defect. The main advantage of this technique is that the flap remains attached at its base so that it retains its own blood supply during transfer to a new position. It also preserves the interdental papilla, thus preserving the gingival height. As an alternative to the epithelial connective tissue graft, amnion membrane has the advantage of no invasive palatal wound, regenerative potential, and improved esthetic results. This procedure is highly sensitive and had predictable results, with a clinically significant amount of root coverage.

Keywords: Amnion membrane, Double papilla technique, Recession, Root coverage.

ABSTRACT

Alveolar bone deficiency is a major postoperative complication in the treatment of traumatic injuries, periodontal diseases and likewise. Hence, alveolar bone repair remains a major hurdle in tissue engineering. Autogenous bone can be wellthought- of as benchmark for bone grafting sans its limitations and complications. In order to overcome these limitations, there is an increased demand of bone graft materials that led to numerous studies on different techniques and materials for bone regeneration over the years. Dentin and bone having same biochemical similarities led to the idea of using it as a bone regenerative material. Demineralized dentin matrix (DDM), an organic material obtained from dentin has been shown to possess osteogenic capacity. Demineralized dentin matrix may prosper in future endodontic world as an apexification material and as a permanent root canal filling material as well. Quick in bone forming as compared to conventional bone graft, this material is a boon to the dental world in this era. This manuscript reviews various studies on different types of DDM as a bone grafting material, and also summarizes the suggested pathway of bone regeneration.

Keywords: Autogenous, Bone, Bone morphogenic protein, Demineralized dentin matrix, Grafting.

ABSTRACT

Background: Early childhood caries (ECC) is a common disease affecting very young children in today’s era. The prevention of ECC depends upon the vital information parents are available with during the upbringing of the child.

Aim: This survey was undertaken to evaluate the awareness among parents about preventive aspects of ECC in Abha City, Kingdom of Saudi Arabia.

Methodology: A questionnaire study was conducted among young parents about preventive aspects of ECC in Abha City, Kingdom of Saudi Arabia. Descriptive statistics was used to observe the awareness.

Results: A total of 157 parents participated in the study of which 126 were mothers and 31 fathers. The mean age of the parents participating in the study was 34 years, and 55% of the participants had education till the university level. About half (53%) of the parents were unaware that the child should be taken for the first dental visit by 1 year of age. Around 60% of the participants had taken their children to the dentist only when the dental problem was in persistence and 48% of the participants allowed their child to sleep with milk bottle or juice in their mouth.

Conclusion: Hence, it can be concluded that the parents in Abha, KSA, are moderately aware of dental needs of their young children.

Keywords: Awareness, Dental caries, Early childhood caries, Knowledge, Saudi Arabia.
