The results for the analysis of the number of instrumental striations (n) counted on each tooth and the number according to their orientation through the occlusal/incisal plane on the El Sidrón adolescent and juvenile Neandertals. * Indicate deciduous teeth. RC: right canine; RI2: right lateral incisor; RI1: right central incisor; LI1: left central incisor; LI2: left lateral incisor; LC: left canine. RO: right-oblique orientation; LO: left-oblique orientation; V: vertical orientation; H: horizontal orientation.
