Their ages ranged from 25 to 40 years with normal BMI (18.5-25) will be divided into subgroups according to neck position during their work. Procedures: Pain intensity will be determined by visual analog scale (VAS), hand grip strength will be measured by Jamar hand dynamometer in kilogram (Kg) unit. Result: Among 25 dentists the result showed extremely significant correlation between neck pain and hand grip strength (direct proportional). The p value (0.0001).
