Objective:Discusses the maxillary the first premolar X-ray method pulp cavity physical quantities of data. Method: Use X line parallel shots were taken tooth cheek entity according to the tongue is about and to X-ray image teeth, according to this paper pulp cavity root canal set points to roots type standard pipe type points. Using the computer matching kodak imaging system measurement (mm) X-ray of the pulp is high, the pulp tooth width, root in diameter, tongue in cheek root diameter, diameter and root root buccal tongue size. SPSS17.0 software with statistical processing X-ray of the medullary cavity teeth physical quantity. Results:In the 100 of the maxillary first premolar in X-ray root tube has 6 type: Ⅰ-1-1 type 33%,Ⅰ-2-2 type 17%,Ⅰ-2-1 type 13%,Ⅰ-1-2 type 4%,Ⅰ-2-1-2 type 3%,Ⅱ-2-2 type 30%. X-ray of the tooth with high of the pulp chambers 3.09±1.18,wide of the pulp chambers 3.88±0.61,diameter of the root middle buccal 1.76±1.18,diameter of the root middle tongue 0.59±0.34,diameter of the root tip buccal 0.79±0.89,diameter of the root tip tongue 0.35±0.28. Medullary cavity physical quantity measured value differences have statistical significance. Conclusion: the results show that Hubei region of the maxillary first premolar root canal are the main types of Ⅰ-1-1, Ⅰ-2-2, Ⅱ-2-2 type. X ray tooth physical measurement by correlation and regression analysis, if there is a correlation between the pair, can be used in regression equation of values of an independent variable ( X ) to estimate the value of the dependent variable ( Y ). Oral clinical practice with the medullary cavity physical quantity unknown data. Tooth teeth by X-ray study physical quantity method is simple, feasible, practical.
