Preferred Abstract (Original): 
This study reports the relationship between occupational noise levels with arterial blood pressure (systolic and diastolic), and heart pulse rate for dentists in their offices chosen randomly in Jenin City. The noise levels measured during operational periods in the chosen dental offices were found to be between 90.5 and 91.7 dB. The arterial blood pressure (systolic and diastolic) and heart pulse rate of doctors were measured before and after exposure to noise for four hours. Positive correlation (Pearson Correlation Coefficient) with noise pollution was found for all measured variables. The mean blood pressure, for examples, has Pearson's Coefficient R = 0.629 for systolic and R = 0.475 for diastolic. In addition, heart pulse rate has a Pearson's Coefficient R = 0.560. This study shows that after four hours of work, there is a significant increase in the mean measured values of blood pressure (systolic and diastolic) and heart pulse rate. The mean of systolic blood pressure, for example, is increased by 4.4 mm-Hg, while the mean of diastolic blood pressure is increased by 3.8 mm-Hg. Finally, the heart pulse rate mean is increased by 3.6 beats/minute.
