Introduction: Dentistry is a demanding profession requiring focus, accuracy, and skills. However, with scientific advances, various new advances and types of equipment have developed enhancing the general dental care. It has been reported that chairs intended for right-handed users result in manual uneasiness or discomfort for left-handed dentists. This might constrain the left handers to adjust, thereby leading to decrease in their performance with increased perception of inconvenience.

“…Still regarding inclusion in the educational environment, the majority of left-handed participants in a study [29] reported that they preferred an educational model that took into consideration the lateral dominance of students and it would be more functional if at least the equipment was mobile/reversible. Some students described reduced clinical performance due to back pain and inadequate work posture.…”

Objectives: To verify the existence of difficulties throughout the course of dentistry clinical practices, identify musculoskeletal pain, and evaluate frequency and intensity of pain/discomfort (if existent) in different regions of the body, experienced by lefthanded students in comparison to right-handed students of the odontology courses of the state of Rio Grande do Norte (Northeast Brazil). Methods: A general questionnaire was applied to identify left-handed students in a population of 750 students, enrolled in clinical courses. An adaptation of the Grad-Corllet Diagram and a specific questionnaire on clinical practices were applied to the selected students.Descriptive statistics was utilized to analyze data of the specific questionnaire, and Mann-Whitney statistics, chi-square or Fisher's Exact tests (with a 5% significance level) were utilized for the Grad-Corllet Diagram, searching for an association between discomfort/pain in different body regions and manual laterality. Results: All students presented higher percentage of pain in the lumbar and neck/cervical regions. However, left-handed students presented higher values, with statistical significance levels of p = 0.041 for lower back, p = 0.002 for neck and p = 0.003 for cervical region. Conclusions: The majority of left-handed students classified "moderate" the difficulty of working with equipment designed for right-handers. There was high frequency of musculoskeletal pain/discomfort, with relevant statistical results for lefthanded students regarding intensity. It is suggested that the participating institutions evaluate the adoption of inclusion politics, re-adapt the infrastructure to include 248equipment designed for left-handers, and finally provide adequate work conditions for all students.

“…It is pertinent to mention that both this and the Nigerian studies used the Edinburgh Handedness Inventory questionnaire (Alibeik and Angaji, 2010). The global prevalence of left-handedness has not yet been established (Odabas et al, 2012). However, it was estimated that 10% of the world's population are left handers (Lui et al, 2012).…”

Work environment in dentistry benefits the right-handed dental practitioners. This situation requires the left-handers to work in an adjusted position causing them discomfort and inconvenience. The aim of this study was to explore the experiences of the identified left-handed undergraduate dental students in Faculty of Dentistry, Universiti Sains Islam Malaysia (USIM) in performing dental procedures. The first phase of the study was to determine handedness of the students using the Edinburgh Handedness Inventory Questionnaire that was distributed to all the dental students. This was followed by a qualitative study using the phenomenology approach. Semi-structured interviews were conducted on left-handed students to determine their perceptions on left-handedness in performing dental procedures. The number of students interviewed was based on attainment of the saturation point. The interview was recorded and transcribed verbatim. The transcripts were analysed through coding, categorising and grouping responses into themes. Prevalence of left-handedness in this faculty was 7%. The participants were not aware of the right-handed situation when they enrolled in the faculty. This situation gave rise to psychological impact such as anxiety and stress. Although some participants were able to use their right hand for certain procedures, the dominant hand continued to be their preference. The difficulties encountered when using the non-dominant hand were grip-strength, angulation and positioning of the instruments. Dental procedures in periodontology (such as scaling, root debridement) and oral surgery (tooth extraction, incision and suturing) were found to be very challenging. They experienced muscle fatigue, reduced precision and prolonged time to complete the dental procedures. They felt that they should be given more time to adapt using the right hand under the tutelage of left-handed faculty members. Left-handed dental students faced difficulties in adapting to the right-handed situation and affect their effectiveness and efficiency. Specific activities need to be designed for left-handers to adapt to the situation under the guidance of left-handed faculty members.
