Comparative study of mandibular linear measurements obtained by cone beam computed tomography and digital calipers.

Objectives: Cone beam computed tomography (CBCT) is an innovative dental of imaging system characterized by rapid volumetric imaging with patient exposure to a single dose of radiation. The present study was carried out to compare the linear measurements obtained with CBCT and digital caliper in 20 mandibles from human cadavers.

Study Design: A total of 4800 linear measurements were measured between different mandibular anatomical points with CBCT and digital caliper.

Relationships between bone density values from cone beam computed tomography, maximum insertion torque, and resonance frequency analysis at implant placement: a pilot study.

Purpose: The aim of the present study was to determine bone density in designated implant sites using cone beam computed tomography (CBCT) and to evaluate possible correlations between age, gender, insertion torque measurements, and resonance frequency analysis (RFA) values.

Materials And Methods: Completely and partially edentulous patients were treated with implants between 2007 and 2008 and evaluated retrospectively. The preoperative examination included a panoramic radiograph, CBCT, diagnostic casts, and a clinical examination of the jaws.

Salivary gland application of botulinum toxin for the treatment of sialorrhea.

Sialorrhea or excessive salivation, and drooling, are common and disabling manifestations in different neurological disorders. A review is made of the literature, based on a PubMed search, selecting those articles describing clinical trials involving the injection of botulinum toxin A in the salivary glands of patients with different diseases characterized by sialorrhea. The most frequently treated diseases were infant cerebral palsy (30%), Parkinson's disease (20%) and amyotrophic lateral sclerosis (15%).
