An Evaluation of Root Length Measurements Using Intraoral Scan and Panoramic Radiographs

2016-07-05 22:38:21 | BioPortfolio


This study will attempt to validate a method of estimating root length on panoramic radiograph by crown measurement on intraoral digital scans.


Intraoral digital scans will be taken on patients who have completed orthodontic treatment, and measurements will be made on the crown dimensions. These dimensions will then be applied onto the same teeth as seen on panoramic radiographs and a mathematical relationship will be determined for root length. Changes in root length will be measured from initial records to treatment complete panoramic radiographs and these estimates will be compared to actual root length changes as measured in CBCT (Cone Beam Computed Tomography) records.

Medical and Biotech [MESH] Definitions

Resorption in which cementum or dentin is lost from the root of a tooth owing to cementoclastic or osteoclastic activity in conditions such as trauma of occlusion or neoplasms. (Dorland, 27th ed)

The use of combination of imaging techniques or platforms (e.g., MRI SCAN and PET SCAN) encompassing aspects of anatomical, functional, or molecular imaging methods.

Resorption of calcified dental tissue, involving demineralization due to reversal of the cation exchange and lacunar resorption by osteoclasts. There are two types: external (as a result of tooth pathology) and internal (apparently initiated by a peculiar inflammatory hyperplasia of the pulp). (From Jablonski, Dictionary of Dentistry, 1992, p676)

Conditions in which a bifurcation or trifurcation of the molar tooth root becomes denuded as a result of periodontal disease. It may be followed by tooth mobility, temperature sensitivity, pain, and alveolar bone resorption.

A large multinuclear cell associated with the BONE RESORPTION. An odontoclast, also called cementoclast, is cytomorphologically the same as an osteoclast and is involved in CEMENTUM resorption.
