dc.description.abstract The macromorphology of pulp chambers has been carefully studied in the last few decades. But there is a serious lack of knowledge on the sizes in different dimensions of the pulp chambers of molars. Aims of the present study are jo measure the range and mean dimensions of the pulp chambers of upper and lower molars; to detect the relation between the sizes of clinical crowns and pulp chambers for better endocavity preparation. 286 upper and lower molars, 161 fi rst and second upper molars, 125 fi rst and second lower molars – matured, fully mineralized and sound are used for the study. Measurements of the clinical crownthree dimensions for each tooth in mm: mesio-distal, from the approximal marginal ridge, bucco-lingual, from the top of buccal cusp to the top of the mesio-lingual (palatal) cusp. The height of the crown is measured from the buccal side. Measurements of the pulp chambers: 40 randomly selected upper and lower molars, 20 in each group without severe root canal curvatures are measured under the following technology: the pulp chambers are opened with horizontal cuts, 1 mm apically from the equator with diamond blend. After polishing the ridges the fi nal size of the endocavity is 2 mm bellow the equator. Both buccolingual dimensions are measured as L1 and L2, and the mean as L with endodontic fi le and endoblock in mm. It can be useful for the lecture courses BL sizes less than ½ of the cusp distance to be avoided for endocavity preparation. A careful approach to this sizes of crowns and chambers can lead to safe hard dental tissues during endocavity preparation and especially careful approach to the approximal walls of the teeth. This fi ndings are important for the prevention of crown fractures, of posts and pins and of crowns and bridges in young age groups. en_US
