Nickel-titanium (NiTi) rotary instruments have transformed endodontics by enabling efficient, predictable root canal shaping. However, concerns persist about their impact on dentin integrity, particularly microcrack formation and long-term fracture risks. This narrative review evaluates evidence on contemporary NiTi systems—including thermally treated alloys and reciprocating files—and their effects on dentin structural integrity. While advanced designs reduce torsional stress, in vitro studies report conflicting outcomes on microcrack induction. Clinicians must balance shaping efficiency with preservation of dentin strength. Further in vivo studies are needed to correlate laboratory findings with clinical outcomes.

Imaging of the dental implant site has become a mandatory protocol, to determine whether the patient can tolerate the surgical procedure. Prior to the invention of Cone Beam Computed Tomography (CBCT), dentists used orthopantomogram (OPG), but it had its limitations. CBCT offers improved accuracy and reduced distortion. The identification of underlying bony pathologies, assessment of bone density, proximity of vital anatomical structures, and prognosis of the implant to be inserted became easier with CBCT.
