Objective To introduce a simple and practical digital equipment for photographic children's oral cavity.Methods Using the existing panoura ULTRA pantomography dental equipment,its axletree pole of imaging carrier bracket and the position of the handle of film box were improved,as a result,the traditional intensifying screen film was changed into the IP board carrying digital X-ray imaging to take pictures and using FCR5000R to read the IP board,and then the acquired images were dealt with through terminal processor,and printed with FUJIFILM DRY PIX7000 laser camera to print.Consequently,the clear digital tooth image with high quality were got.Results 200 children were examined randomly with the improved pantomography dental equipment.The excellent image guality was up to 98%.Conclusion The improved pantomography dental equipment is of advantages,and it should be of a promising future in the field of oral cavity clinic,scientific research and teaching.

Objective To introduce a kind of simple and practical digital dental photographic equipment. Methods PanouraULTRA Orthopantomograph dental equipment was adopted to improve its axletree pole of imaging carrier bracket and the position of the handle of film box, so as to make it possible to change the traditional screen film into the IP board carrying digital X-ray imaging to take pictures. By reading the IP board with FCR5000R read implement, dealing with the acquired images through terminal processor, and then using FUJIFILM DRY PIX7000 laser camera to print, a highly clear digital tooth image with high quality would be got. Results Taking Orthopantomograph photos with the improved imaging carrier bracket, successful photos were over 98% of the total. Conclusion This applied machine is characterized by several advantages as follows: appropriate design, convenient operation, low cost, energy-saving and environment protection; high quality of imaging and low quantity of radiation. It can be combined with PACS, which is convenient for distant consultation. This equipment has a promising future in the fields of clinical oral cavity, scientific research and teaching.
