Background: Left-handedness has been considered a simple inconvenience by some or something as convoluted as "the sinister," the Latin word for the left, by others. It has been suggested that majority of the humanity are right-handed because their early hominid ancestors are thought to have linked early speech to muscle actions already lateralized to our brain's left hemisphere at an earlier point in hominid evolution 9. Although, the level of modern technology enables the adaptation of the workplace for both groups of students (lefties and righties) under the same conditions, ensuring equal comfort for them all and avoiding possible psychophysical harm.
Objective: To find if there are any difficulties faced by Left-Handed dentists and dental students, identify these difficulties and how can we overcome them .
Methodology: The research was conducted through a paper and pencil questionnaire that was distributed to dentists , dental students and interns in 4 dental colleges in different regions in United Arab Emirates . The number of participants was 46, the age range was between 20-75 years old, among them there was 24 Female and 22 male.
The collected data were analyzed with the SPSS Inc., Chicago, IL; version 16.0. Descriptive statistics were used to summarize the responses,and independent proportional t-test were used to compare differences.
Results: the study found that out of the 46 participants n=8 (17.4%) were ambidextrous and n=38 were left handed. There was highly significant difference between the LH Students and Dentists ( i.e. r=0.68) and p=0.54 . The Survey revealed that 84.6% of the dentists and 57.6% of the students works on a right handed dental unit. 30.8% of the dentists and 6.1% of the students were forced to change laterality.61.5 % of the dentist and 36.4% of students reported not receiving guidance from their supervisor, and that their institution is not properly equipped . Not forgetting to mention that 76.9% of the dentists and 63.6 % of the students declared facing difficulties. 73.9%of the respondents reported having musculoskeletal complications due to the use of facilities of RH dentists. 69.2% of the dentists and 60.6% of the students sees that being a left-handed will affect the assistant’s ability to work.
Conclusion:The conclusion from this study is to highlight the needs of this minority group as many LH dental students face challenges. Dental schools should provide LH students with needed equipment and a proper learning environment. Expert senior LH dentists should help junior LH dental students to learn techniques and procedures used by left-handers.
