Ba.kground: There is pa.city of litera.ure on the determ.na.ion of the root ca.a. length of Ba.tu subjects in denta. professiona. pra.ticing in a.rica.a.d Dem.cra.ic Republic of Congo in pa.ticula.. a.m.: The a.m.of the present study wa. to determ.ne the root ca.a. length of teeth of Ba.tu pa.ients extra.ts a.tending the Tea.hing Hospita. of Kinsha.a.University. m.thods a.d m.teria.: Prospective cross-sectiona. study wa. ca.ried out in the service of Conserva.ive Dentistry. The pa.ients suffering with pulpitis of perm.nent teeth which were selected for root ca.a. trea.m.nt during the period of Ja.ua.y 2014 to Decem.er 2016 were included. a.l pa.ients whose m.in root ca.a.s were ina.cessible, teeth ca.rying prosthesis, teeth with la.ge corona. deca., teeth ha.ing peria.ica. periodontitis, supernum.ra.y teeth, wisdom.a.d prim.ry teeth were excluded. Results: The upper ca.ines presented som. significa.t longer ca.a.s com.a.ed to the lower ca.ine (23.4 ± 2.3 m. a.d 21.6 ± 1.8 m.). Pa.a.a. ca.a.s of the first a.d second m.la. were respectively longer a. com.a.ed to the superior teeth ca.a.s (21.5 ± 1 m., 21.3 ± 2 m.). The dista. ca.a.s of the first a.d second m.la. were the longest in the m.ndibula. a.ch respectively m.a.uring 20.7 ± 2.0 m. a.d 21.5 ± 1.7 m..

This study sets out to determ.ne the species diversity a.d im.lica.ions for biodiversity conserva.ion in Fm. 09-025 of the Ca.0}o m.’a. Na.iona. pa.k, South Region of Ca.0}roon. Due to hum.n a.tivities in the a.ea. the study site wa. divided into two Blocks (a.a.d B).
