Aim & Objective The aim of the present study was to assess the unpredictable working postures of dentists using the postural analysis tool, Rapid entire body assessment (REBA) and Rapid Upper Limb Assessment (RULA). Materials and Methods: The study was conducted on one hundred and seventy five dentists working in different clinics having an experience of 3 to 20 years with age ranging from 25 – 50 years. Posture was assessed using the posture analysis tools like Rapid entire body assessment (REBA) and Rapid Upper Limb Assessment (RULA). Data are collected about the body posture, forces used, type of movement or action, repetition, and coupling. After the data for each region is collected and scored, tables on the form are then used to compile the risk factor variables, generating a single score that represents the level of MSD risk. Results: The REBA score for 85% of the subjects were 7 and above which indicates the risk level is medium to high. The RULA Score for most of the subjects (54%) were left 3 and right 5. This score indicates investigation and changes may be required in their posture. 47% of subjects were having a left score 4 and right score 5&6
