Periapical
The tissue that appears as a fine white line surrounding the root of the tooth in a dental x-ray is known as the periodontal ligament. It helps to attach the tooth to the surrounding bone and provides support and stability to the tooth.
Connective tissue coverings surrounding muscles include the epimysium (surrounding the entire muscle), perimysium (surrounding bundles of muscle fibers or fascicles), and endomysium (surrounding individual muscle fibers). For nerves, the coverings are the epineurium (surrounding the entire nerve), perineurium (surrounding bundles of nerve fibers), and endoneurium (surrounding individual nerve fibers). In bones, the periosteum covers the outer surface, while the endosteum lines the inner surfaces.
The perimysium is the connective tissue that surrounds a fascicle (bundle of muscle fibers), while the epimysium surrounds the entire muscle. The endomysium is a connective tissue sheath that surrounds individual muscle fibers within a fascicle.
The hardened deposits that form on the teeth and can irritate the surrounding tissue, is called tartar or dental calculus. If good oral hygeine is not practiced, tartar can build up on the teeth and become hardened. This can irritate the gums and cause them to bleed.
D7951 refers to a specific code in dental coding, particularly within the American Dental Association's Current Dental Terminology (CDT) system. It describes the surgical access of an unerupted tooth, typically involving the removal of bone or tissue to expose the tooth. This procedure is often necessary for impacted teeth, such as wisdom teeth, that may not emerge properly. For an accurate diagnosis, clinical evaluation and radiographic imaging are essential.
excisional and incisional. An excisional biopsy is a surgical procedure where the entire area of concern and some surrounding tissue is removed
An operculectomy is a dental procedure that is performed to remove to remove a flap of tissue surrounding an impacted tooth. The ADA code for this procedure is D7971 for the excision of pericoronal gingiva.
Pericardectomy is surgical removal of a portion or all of the tissue surrounding the heart. This tissue is known as the pericardium.
The eponychium, also known as the cuticle, is the thickened layer of skin surrounding fingernails and toenails.
Overall darkness of a radiographic image, also known as radiographic density, refers to the degree of blackening on the image. It is influenced by factors such as exposure factors (milliamperage, kilovoltage, exposure time), processing techniques, and characteristics of the anatomical structure being imaged. A darker image generally represents increased tissue density or thickness.
To open a calcified root canal, a dentist typically starts by using a dental microscope for enhanced visibility. They may employ ultrasonic instruments or specialized rotary files to carefully locate and negotiate the canal while applying gentle pressure. Additionally, a chelating agent can be used to soften the calcified tissue, facilitating access. Throughout the process, continuous radiographic monitoring can help ensure proper navigation without damaging surrounding structures.
