Prevalence of Ocular Injuries, Conjunctivitis and Musculoskeletal Disorders-Related Issues as Occupational Hazards Among Dental Practitioners in the City of Salem: A Randomized Cross-Sectional Study.

J Pharm Bioallied Sci 2019 May;11(Suppl 2):S335-S337

Department of Conservative Dentistry and Endodontics, Vinayaka Missions Sankarachariyar Dental College, Salem, Tamil Nadu, India.

Background: Similar to several other occupations, dentists are also stricken by bounteous occupational health hazards (OHHs) such as musculoskeletal disorders (MSDs) and ocular health-related issues.

Aims: The aim of this study was to evaluate the diffusion of MSDs and ocular health-related issues among dental surgeons in Salem city, Tamil Nadu, India, according to age, sex, and number of practicing hours per week.

Objectives: A survey was conducted to examine the rate of prevalence of these OHHs amidst the dental surgeons in Salem city.

Materials And Methods: The study was performed through a questionnaire amidst 150 dentists practicing in Salem City, Tamil Nadu, India. Dental surgeons were questioned about any occupational disorder that they had experienced related to a musculoskeletal pain and its location whether in the back, upper limbs, or lower limbs. In extension to this, dental surgeons were asked about any ocular injury that they had.

Results: MSD showed higher rate of occurrence correlated to ocular health-related issues.

Conclusion: The practice of protective measures is crucial, in perspective of the high rate of these disorders in the community of dental surgeons.

Erosion Infiltration Technique': A Novel Alternative for Masking Enamel White Spot Lesion.

J Pharm Bioallied Sci 2017 Nov;9(Suppl 1):S289-S291

Department of Conservative Dentistry and Endodontics, Vinayaka Missions Sankarachariyar Dental College, Salem, Tamil Nadu, India.

Enamel White spot lesions are early signs of demineralization under the intact enamel, which may or may not lead to the development of caries. An inactive white spot lesion might act as an arrested dental caries and impair the esthetic appearance by displaying a milky white color from its interior opacity. The first choice of treatment is remineralization with various remineralizing agents such as fluoride and ACP-CCP. Caries infiltration is a less invasive and effective method for arresting the white spot lesions. It also improves the esthetics by masking the chalky white appearance by the process of optical adaptation to the adjacent healthy enamel. This is achieved by the hydrophobic resin, which has a similar refractive index to that of the healthy enamel.

Musculoskeletal Disorders and Mental Health-related Issues as Occupational Hazards among Dental Practitioners in Salem City: A Cross-sectional Study.

J Pharm Bioallied Sci 2017 Nov;9(Suppl 1):S228-S230

Department of Conservative Dentistry and Endodontics, Vivekanandha Dental College for Women, Tiruchengode, Tamil Nadu, India.

Background: Like in any other profession, dental surgeons are also afflicted by many occupational health hazards such as Musculoskeletal disorders (MSD) and mental health related issues.

Aims: To assess the distribution of MSD and mental health related issues amidst dentists in Salem City according to age, sex and number of working hours per week.

Objectives: A survey was organized to check the rate of occurrence of these occupational health hazards among dental practitioners in Salem city.

Materials And Methods: The study was conducted among one hundred and fifty dentists practicing in Salem City in the form of questionnaire. Dentists were asked about any occupational disease that they suffered related to a musculo-skeletal pain and its location whether in the back, upper limbs or lower limbs. In addition to this, dentists were asked about mental stress that they had experienced.

Results: MSD showed higher rate of prevalence compared to mental health related issues.

Conclusion: The application of preventive measures is necessary, in view of the high rate of these disorders in the society of dental practitioners.

Effect of Biomineralization Ability on Push-out Strength of Proroot Mineral Trioxide Aggregate, Mineral Trioxide Aggregate Branco, and Calcium Phosphate Cement on Dentin: An Evaluation.

J Pharm Bioallied Sci 2017 Nov;9(Suppl 1):S121-S126

Department of Oral Medicine and Radiology, AJ Shetty Dental College, Mangalore, Karnataka, India.

Context: Biomineralization is a process which leads to the formation of an interfacial layer with tag-like structures at the cement-dentin interface. It is due to interaction of mineral trioxide aggregate (MTA) and Portland cement with dentin in phosphate-buffered solution (PBS). This study is aimed to evaluate the effect of influence of biomineralization process on push-out bond strength of ProRoot MTA (Dentsply Tulsa Dental, Tulsa, OK, USA), MTA Branco (Angelus Soluc¸o˜es Odontolo´gicas, Londrina, PR, Brazil) and calcium phosphate cement (BioGraft CPC).

Aim: The aim of this study was to evaluate the effect of biomineralization process on the push-out strength of ProRoot MTA, MTA Branco, and CPC after mixing with 0.2% chlorhexidine gluconate solution (0.2% CHX) and 2% lidocaine solution (2% LA) on the bond strength of MTA-dentin.

Materials And Methods: Dentin discs with uniform cavities were restored with ProRoot MTA, MTA Branco, and calcium phosphate cement after mixing with 0.2% CHX solution and 2% lidocaine solution. The samples were uniformly distributed into two groups. Experimental group being immersed in PBS solution and control group being immersed in saline for 2 months. Instron testing machine (Model 4444; Instron Corp., Canton, MA, USA) was used to determine the bond strength.

Statistical Analysis Used: A two-way analysis of variance and analysis by Bonferroni test.

Results: All samples immersed in experimental group displayed a significantly greater resistance to displacement than that observed for the samples in control group ( < 0.05). MTAs displayed a significantly greater resistance to displacement than calcium phosphate cements.

Conclusion: The main conclusion of this study was that the push-out bond strength of the cements, mainly the MTA groups, was positively influenced by the biomineralization process.

Apical Extrusion of Intracanal Bacteria following use of Two Engine-driven Instrumentation Techniques: An in vitro Study.

J Contemp Dent Pract 2016 Nov 1;17(11):939-942. Epub 2016 Nov 1.

Department of Conservative Dentistry and Endodontics, The Vinayaka Mission's Sankarachariyar Dental College, Salem Tamil Nadu, India.

Aim: The aim of the present study was to compare in vitro the amount of debris extruded apically from extracted teeth, using Twisted files and ProTaper rotary during two different instrumentation systems.

Materials And Methods: Forty-five human single-rooted mandibular premolar teeth were randomly divided into three groups and contaminated with Enterococcus faecalis. The teeth in experimental groups were instrumented until reaching the working length with ProTaper rotary instruments and Twisted files with XSmart and XSmart Dual groups. Debris extruded from the apical foramen was collected into glass vials and the amount of bacteria was calculated. The data obtained were analyzed using Kruskal-Wallis one-way analysis of variance and Mann-Whitney U tests, with p = 0.05 as the level for statistical significance.

Results: The XSmart Dual group extruded comparatively lesser bacteria compared to the XSmart group. Lesser amount of bacterial extrusion was seen when Twisted files were used compared to the ProTaper files (p < 0.05).

Conclusion: Under the circumstances of this in vitro study, it can be concluded that all instrumentation techniques produced measurable apical extrusion of debris. So, it is upon the practitioner to decide which system best fits their individual needs and their level of skill and experience that will provide the best possible endodontic care for our patients.

Clinical Significance: The newer instrument designs, including noncutting tips, different cross sections, radial lands, and variable tapers, are better for the clinicians to improve working safety, to reduce the working time, and to create a greater flare within the preparations.
