Background: Knowledge about the anatomy of root canals is an important facror in the prognosis of  root canal  therapy .The purpose  of  this  study is to derermine  the root  canal
anatomy in  mandibalar anterior  reeth and  premolars by clear and dye peneration
method.
Materials and methods:In this  study, 350 human mandibular anterior teeth and  mandibular  and  maxillary premolars(from each:50 teeth)were used to determine the number of root canals and accessory and lateral canals . The examination of  root  canal  systems was  based on vertucci’s classification and with the method of clear and dye penetration with a little difference to compare with other researches.
Results:The frequency of type I in central,lateral incisors and cuspids averaged 84.%78and %94, type II:%10 ,%12 and%4, typeIII%2 ,%2 and%0, typeIV averaged%8 and%2. The frequency  of lateral  canals  in these  teeth averaged %10 , %12  and %10 and accessory canals averaged %24,%28 and%20.
The frequency of type I in mandibular premolars averaged %78 and%90,typeII%2 and%4,typeIV%6 and %4, type V averaged %14 and%2.The frequency of lateral canals in these teeth was %34 and %28 and accessory canals was %20 and %20.
The frequency of type I in maxillary permolars averaged %10, %54, typeII %24 and %20, type IV %4 and %24 , type V averaged %2 and %2. The frequency of lateral canals in these teeth was %14 and %4 and accessory canals averaged %18 and %22.
Conclusion : Our method with a little difference to compare with other researches is a good and precise way for evaluation of root canal anatomy.
