ABSTRACT
Cone-beam computed tomography (CBCT) is routinely recommended for dental diagnosis and treatment planning. CBCT exposes patients to less radiation than does conventional CT. Still, lack of proper education among dentists and specialists is resulting in improper referral for CBCT. In addition, aiming to generate high-quality images, operators may increase the radiation dose, which can expose the patient to unnecessary risk. This letter advocates appropriate radiation dosing during CBCT to the benefit of both patients and dentists, and supports moving from the concept of "as low as reasonably achievable" (ALARA) to "as low as diagnostically acceptable" (ALADA).
ABSTRACT
Panoramic radiography and computed tomography were the pillars of maxillofacial diagnosis. With the advent of cone-beam computed tomography, dental practice has seen a paradigm shift. This review article highlights the potential applications of cone-beam computed tomography in the fields of dental implantology and forensic dentistry, and its limitations in maxillofacial diagnosis.
ABSTRACT
Sodium hypochloride is the most commonly used endodontic irrigant, despite limitations. None of the presently available root canal irrigants satisfy the requirements of ideal root canal irrigant. Newer root canal irrigants are studied for potential replacement of sodium hypochloride. This article reviews the potential irrigants with their advantages and limitations with their future in endodontic irrigation.
ABSTRACT
BACKGROUND: Lingual vascular canal (LVC) is an important anatomical structure in mandibular anterior region. Trauma to this structure during implant placement has been reported in this study. Dental computed tomography (DCT) provides a three-dimensional visualization of lingual vascular canal. AIM: To assess the frequency, location, and size of LVC using dental CT. MATERIALS AND METHODS: A retrospective analysis of 75 mandibular DCT was done. Evaluation was done to detect the frequency, size, and number of lingual vascular canal using Seimens Somatom Sensation 64. RESULTS: About 73.3% patients (male=34, female=21) demonstrated presence of LVC with only one patient showing two canals. The mean distance from the inferior border of mandible was 0.5 mm, S.D.±0.70. The mean diameter of the canal was 0.31 mm, S.D.±0.70. CONCLUSION: Dental CT provides adequate information regarding frequency, number, and size of lingual vascular canal, which is an important anatomical structure in mandibular anterior region.
