Patient Entrance Doses from Intraoral Dental Radiography in Regional Health 2

Abstract

Intraoral dental radiographic examinations are used to diagnose and monitor oral diseases.

Therefore, should using radiation dose to the maximize benefits and minimal radiation dose. The primary risk is radiation - induced cancer. Patient entrance doses (PED) was studied by Regional Medical Sciences Center 2, Phitsanulok, including Phitsanulok, Phetchaboon, Uttaradit, Sukhothai and Tak. Eighty - eight of intra-oral X-ray units were forty-five hospital and forty-three dental clinics from 2013 to 2015.Patient entrance doses (PED) in adult patients from 6 types including upper anterior, upper premolar,upper molar, lower anterior, lower premolar and lower molar were measured by solid state detector. The third quartile of the group were 2.8, 4.0, 5.0, 2.5, 3.0, and 3.8 milligray, respectively. The radiation dose used in the imaging of upper molar teeth of adults which higher the diagnostic reference levels (DRL) of European guidelines of thirty-three units (37.5%). They were compared the radiation doses of hospitals and dental clinics did not differ statistically significant (p>0.05). In conclusion, the radiation dose patients receive higher than the reference value. Therefore, using high dose of hospitals and dental clinics should edit causal factors of the high doses and improve the current techniques to suit reduce patient dose to be as low as possible and lower than the reference dose.
