Background: Pulp capping should always be considered as the primary treatment of choice for teeth without irreversible pulpitis in lesions approaching dental pulp. The predictability of vital pulp therapy has improved with the introduction of newer bioceramic materials.

Aim: The purpose of this randomized controlled trial was to compare the outcomes of mineral trioxide aggregate (MTA) (Angelus, Londrina, Brazil) and a pozzolan-based cement (ENDOCEM-Zr [Maruchi, Wonju, Korea]) as an indirect pulp capping (IPC) material.

Materials And Methods: IPC was performed in forty patients who were randomly divided into ENDOCEM-Zr and MTA groups. The outcome was assessed using clinical and radiographic tests at different time intervals. The prognostic factors on the outcome of IPC were also evaluated.

Results And Conclusions: The success rate of ENDOCEM-Zr and MTA groups was 94.7% and 89.4%, respectively. The results were not statistically significant. Binary logical regression showed that the age of the patient and the status of the pulp before treatment were deciding variables for the outcome of the study. Therefore, it was concluded from the study that the evaluated pozzolan-based cement could be used as an alternative to MTA because of its faster setting time and lower discoloration potential. In addition, pulp capping should be performed with caution in individuals above 40 years and in teeth with reversible pulpitis.

Evaluation of the effectiveness of fluoridated and non-fluoridated desensitizing agents in dentinal tubule occlusion using scanning electron microscopy. An in-vitro study.

Dent Res J (Isfahan) 2020 May-Jun;17(3):193-199. Epub 2020 May 23.

Department of Oral Pathology and Microbiology, Manipal College of Dental Sciences, Mangalore, Affiliated to Manipal Academy of Higher Education, Manipal, Karnataka, India.

Background: Dentin hypersensitivity is primarily caused due to patent or exposed dentinal tubules. Nonfluoridated-desensitizing agents deposit hydroxycarbonate apatite (HCA), within the dentinal tubules, thereby relieving hypersensitivity. Fluoride-containing bioactive glass-based agents form fluorapatite which is less soluble when compared to hydroxyapatite and HCA.

Materials And Methods: In this study forty dentin specimens obtained from extracted human premolars were divided randomly into four groups ( = 10): Group 1 - fluoridated bioactive glass (FBaG); Group 2 - bioactive glass (BaG); Group 3 - arginine calcium carbonate; Group 4 - saline. 37.5% phosphoric acid was used to ensure patent dentinal tubules. Test agents from each group were applied using a rubber cup. Half the treated samples were then subjected to 6% citric acid treatment. The degree of occlusion was evaluated using the scanning electron microscope, and the microscopic images were scored before and after the citric acid challenge by two blinded endodontists. Statistical analysis was performed using SPSS, one-way ANOVA, and post hoc Tukey test ( = 0.05).

Results: Group 1 demonstrated better tubule occlusion in comparison with Group 2 and a statistically significant difference when compared to Group 3 ( = 0.001). Following acid challenge, Group 2 showed significantly more occluded tubules when compared with Group 3 ( = 0.001) and comparable difference with Group 1.

Conclusion: All desensitizing agents showed satisfactory dentinal tubule occlusion. While fluoridated bioactive glass demonstrated better occlusion immediately after application, Bioactive glass showed better resistance to acid treatment.

Association of level of education and utilization of restorative dental care among rural women in India: Cross-sectional study.

Indian J Dent Res 2017 Nov-Dec;28(6):642-645

Department of Public Health Dentistry, Manipal College of Dental Sciences, Manipal University, Mangalore, Karnataka, India.

Background: The utilization of restorative dental care is very scarce in rural India. Association between level of education and health of a person has been well-documented in many countries and time periods with a range of potential factors shaping the connection between both.

Objectives: This cross-sectional survey was conducted to evaluate an association between the level of education (educational qualification) and utilization of restorative dental care among rural women associated with self-help groups.

Materials And Methods: A semi-structured questionnaire was administrated to 660 rural women associated with self-help group by trained research assistants. The 604 completed questionnaires were received and reviewed. The education levels were divided into three groups: Group 1 - illiterates (17.2%), Group 2 - school educated (69.4%), and Group 3 - college educated (13.4%). Chi-square test was applied to evaluate the utilization of dental services by rural women, and logistic regression was applied to evaluate the influence of their educational qualifications on utilization.

Results: A total of 604 properly filled questionnaires out of 660 (91.51% response rate) were included in the analysis. Only 56.9% of the sampled rural women indicated that they have visited dentists earlier. The maximum number of individuals who have never visited the dentist belonged to illiterate group (55.7%), and the association was statistically significant (0.004) when compared with educated individuals.

Conclusion: The results of this study concluded that the level of education has a significant influence on the utilization of dental care.

One-step apexification using platelet rich fibrin matrix and mineral trioxide aggregate apical barrier.

Indian J Dent Res 2014 Nov-Dec;25(6):809-12

Department of Conservative Dentistry and Endodontics, Manipal College of Dental Sciences, Mangalore, Manipal University, Manipal, Karnataka, India.

The absence of a natural apical constriction in a nonvital young permanent tooth makes endodontic treatment a challenge. There is a need to induce or create an apical barrier against, which the obturating material can be condensed. Traditionally, calcium hydroxide is the material of choice to induce apexification. Due to certain drawbacks such as prolonged treatment duration and unpredictable apical barrier formation, it is being replaced by materials, which have a more predictable outcome like mineral trioxide aggregate (MTA). One-step apexification with MTA reduces the treatment time when compared with traditional calcium hydroxide apexification, which requires an average time of 12-19 months. In one-step apexification using MTA, the technical problem encountered is controlling the overfill or underfill of MTA. The use of a matrix material helps to overcome this shortcoming. Platelet rich fibrin (PRF) is an immune platelet concentrate, which can be used as a matrix, it also promotes wound healing and repair. This case report presents a case of one step apexification using MTA as an apical barrier and autologous PRF as an internal matrix.

Evaluation of calcium ion release and change in pH on combining calcium hydroxide with different vehicles.

Contemp Clin Dent 2014 Oct;5(4):434-9

Department of Conservative Dentistry and Endodontics, Manipal College of Dental Sciences, Affiliated to Manipal University, Mangalore, Karnataka, India.

Introduction: Intracanal medicaments have traditionally been used in endodontics to disinfect root canals between appointments. Calcium hydroxide is widely used as an intracanal medicament for disinfection and to promote periapical healing. It is stable for long periods, harmless to the body, and bactericidal in a limited area. The efficacy of calcium hydroxide as a disinfectant is dependent on the availability of the hydroxyl ions in the solution that depends on the vehicle in which the calcium hydroxide is carried. In general, three types of vehicles are used: Aqueous, viscous or oily. Some in vitro studies have shown that the type of vehicle has a direct relationship with the concentration and the velocity of ionic liberation as well as with the antibacterial action when the paste is carried into a contaminated area.

Aim Of The Study: To evaluate the calcium ion release and measure the change in pH of the environment that occurred when calcium hydroxide was combined with different vehicles (distilled water, propylene glycol, calcium hydroxide containing gutta-percha points and chitosan) over different time periods.

Materials And Methods: Forty single rooted mandibular first premolar teeth were decoronated for this study. Working length was established and the root canals were enlarged and irrigation accomplished with 2 ml of NaOCl solution after every file. The teeth were then randomly divided into four groups. The canals were then packed with different preparations of calcium hydroxide using the following vehicles-distilled water, propylene glycol, gutta-percha points and chitosan. Calcium ion release in different groups was analyzed using an ultraviolet spectrophotometer at 220 nm. The change in pH of was determined using a pH meter. Results were statistically evaluated using one-way ANOVA test.

Result: For calcium ion release, Group 2 showed cumulative drug release of 81.97% at the end of 15 days, whereas Group 1, 3 and 4 showed a release of 99.53, 17.98, 74.93% respectively with a significant difference among all groups. Group 1 reached the highest Ca(2+) level (39.79%) at the end of 1 day but showed almost complete release of calcium hydroxide at the end of 15 days. Group 3 showed least calcium ion release (17.98%) at 15 days. Group 4 showed a sustained release of Ca(+2) ions from 74% at 15 days to 95% at the end of 30 days. After the 1(st) h; Group 1 showed the highest pH level (11.8). However, pH reduced to 7.8 at the end of 30 days in this group. Group 2 showed the highest pH value (10.35), followed by Group 4 (10.32) after 30 days.

Conclusion: Chitosan can be used as a promising vehicle for calcium hydroxide to maintain an alkaline pH and to allow sustained release of calcium ions in the root canal system.
