title: [Evaluation of normal submandibular gland function by sialo-scintigraphy].
abstract: OBJECTIVE
  To study the normal glandular function of the submandibular gland as a background for evaluation of changes in submandibular gland diseases.
  
  
  METHODS
  The backgrounds of both submandibular area and temporal area were analyzed comparatively with Emission Computerized Tomography in eleven pairs of normal submandibular gland.
  
  
  RESULTS
  About 2.18 times of the temporal background equals to submandibular area background; the Concentrate Index of normal submandibular gland was 1.42 +/- 0.89; the Secretory Index was (109.4 +/- 39.8)%, the Secretory Index Ratio and the Concentrate Index Ratio were (77.2 +/- 17.2)% and 71.0 +/- 15.2% respectively; and the Function Index was (89.9 +/- 7.4)%.
  
  
  CONCLUSIONS
  The use of submandibular area background and functional index to represent submandibular gland function is more accurate and more sensitive. Normal functional index can provide the basis for researching submandibular gland disease.
