Introduction:The p.oven radio sensitivity and the p.sition of the thyroid gland make it a significant organ during the dental radiograp.y ***:This study comp.red the surface radiation dose to the thyroid gland region during two different techniques of two dimensional(2D)conventional orthop.ntomograp.y(Op.)and three dimensional(3D)Op. reconstructed from cone beam comp.ted tomograp.y(CBCT).Methods:The entrance surface dose to the thyroid region of the p.tients was evaluated using a p.rsonal dosimeter in a samp.e of 156 p.tients who p.escribed for an Op. ***:The obtained mean dose values for conventional Op. and reconstructed Op. from CBCT are 7.47μSv and 28.65μSv,*** a significant difference(p.0.05)was observed between those two ***:A significant amount of dose reduction to the thyroid gland region can be obtained when using conventional Op. comp.red to the CBCT.
