Background Better understanding of the danger zone anatomy in mesial roots (MRs) of
mandibular first molars (MFMs) may serve to decrease the risk of mishaps. This study aimed …

Introduction This study aimed to evaluate the effects of root canal enlargement on the
danger zone (DZ) of mandibular molars. Methods Thirty mesial roots of mandibular first …

Objectives This study evaluated the danger zone (DZ) in mesial roots of mandibular molars
and the correlation between anatomical references of the DZ and some anatomical …

Objectives This study aimed to evaluate the effects of different shaping protocols on the root
canal geometry and remaining dentin thickness of mandibular premolars with radicular …

Objective The effects of brushing on shaping with three different instruments were assessed
in oval canals. Design Mandibular incisors were assigned to 6 groups (n= 12/group) …

Background The preparation of the middle mesial (MM) canal of mandibular molars
represents a challenge because it is often curved, narrow, and close to the root concave …

Aim. To determine the minimum dentin thickness in the mesial and distal walls of the
mesiobuccal (MB) and mesiolingual (ML) canals of the mandibular first molars using cone …

BACKGROUND: Mandibular first molars appear to be the most commonly tooth subjected to
a root canal treatment, therefore a better understanding of the anatomy critical zones for …

Results: There was no statistically significant difference between two experimental groups in
terms of remaining dentin thickness at 2 and 4 mm levels below the highest point of the …

Objective: The purposes of the present study were to evaluate dentine thickness and
concavity depth below the furcation level of the mesial canals of the mandibular first and …
