Background:Macro-bond strength tests resulted in cohesive failures and overestimation of bond strengths. To reduce the flaws, micro-bond strength tests were introduced. They are the most commonly used bond-strength tests.Objective:Thus the objective of this review is to critically review the reliability of micro-bond strength tests used to evaluate resin-tooth interface.Data Collection:Relevant articles published between January 1994 and July 2013 were collected from Pubmed database, Google scholar and hand searched journals of Conservative Dentistry, Endodontics and Dental materials.Data Synthesis:Variables that influence the test outcome are categorized into substrate related factors, factors related to specimen properties, specimen preparation and test methodology. Impact of these variables on the test outcome is critically analyzed.Conclusion:Micro-bond tests are more reliable than macro-bond tests. However, no standard format exists for reporting the bond strength tests which could lead to misinterpretation of the data and bonding abilities of adhesives.

Adhesive systems are selected based on their bond strengths achieved while testing in laboratories. These bond strengths can predict the longevity of a restoration to some extent. There were several discrepancies in the reported bond strengths. To critically review the reliability of macro-bond strength tests used to evaluate resin-tooth interface. Relevant literature published between January 1983 and May 2013 was collected from PubMed database, Google scholar, and hand-searched journals of Conservative Dentistry, Endodontics and Dental materials. Variables that influence the test outcome are categorized into substrate-related factors, factors related to specimen properties, preparation of specimens, and test methodology. Impact of these variables on the test outcome is critically analyzed. There is lack of a standard format for reporting the bond strength tests, which could lead to misinterpretation of the data and bonding abilities of adhesives.

Odontogenic myxomas are benign but locally aggressive neoplasms found almost exclusively in the jaws and arise only occasionally in other bones. We present a rare case of odontogenic myxoma occurring in the mandible of a 19-year-old male patient with a brief review of clinical and radiological features, and diagnostic and operative dilemmas in managing the same.

Background:Work related musculoskeletal disorders (MSDs) are one of the common occupational hazards among health care providers.Aim:The objective of this study was to evaluate MSDs in terms of perception of pain experienced by physicians, surgeons and dental surgeons during professional work.Subjects and Methods:The study was conducted with 100 physicians practicing either modern or alternative medicine, 100 surgeons of various specialties and 100 dental surgeons. Self-reporting work related questionnaire on MSDs were distributed, including information on the location of MSD symptoms in the past 12 months and the pain experienced.Results:Musculoskeletal pain was most prevalent among dentists 61% (61/100), followed by surgeons 37% (37/100) and physicians 20% (20/100). Nearly 15% of physicians (3/20), 40% (15/37) of Surgeons and 60% (35/61) of Dentists had MSD problems in more than one site.Conclusion:Within the limitations of the study, there is a higher prevalence of MSDs experienced by dental surgeons than physicians and surgeons. More research is needed on musculoskeletal problems with dental surgeons and other specialty doctors with an emphasis on a larger sample sizes and correlating other factors such as age and sex of the doctor, duration of practice, working hours per week, physical activity and working environment.

Background:Work-related musculoskeletal pain is one of the occupational hazards in dentists. Aims: To find the prevalence and severity of musculoskeletal pain in dentists, to compare musculoskeletal pain among dentists practicing yoga, those practicing physical activities, and those without any physical activity, and also to know the effects of sex, age, and workload on musculoskeletal pain.Materials and Methods:A self-reporting work-related questionnaire and the Nordic questionnaire for analysis of musculoskeletal disorders were given to graduated dentists attending Indian dental conference in Mumbai, to know the musculoskeletal pain experienced in the last 12 months and feedback was obtained from 220 dentists.Results:The prevalence of musculoskeletal pain in dentists was 34.5%. Prevalence of musculoskeletal pain was 10.5%, 21.7%, and 45.6% in dentists with regular yoga practice, other physical activity, and no physical activity, respectively. There was statistically significant difference in the prevalence of musculoskeletal pain among dentists who were practicing yoga when compared with those in no regular activity group.Conclusion:Within the limitations of the study, there was significant role of physical activity on the quality and quantity of work-related musculoskeletal disorders experienced by dentists. Yoga was found to be more effective than other modes of physical activities. More research is needed on musculoskeletal problems in dentists, with an emphasis on larger sample sizes and correlating other factors like age and sex of the dentists, duration of practice, years of practicing yoga, and working hours per week.
