This is referred to as a white spot lesion, an incipient carious lesion, or a "micro-cavity". [13] As the lesion continues to demineralize, it can turn brown but will eventually turn into a cavitation ("cavity"). Before the cavity forms, the process is reversible, but once a cavity forms, the lost tooth structure cannot be regenerated. A lesion ...
Non-carious cervical lesions on an incisor belonging to Australopithecus africanus. Arrows show the location of the lesions. Non-carious cervical lesions (NCCLs) are a group of lesions that are characterised by a loss of hard dental tissue at the cementoenamel junction (CEJ) region at the neck of the tooth, without the action of microorganisms or inflammatory processes. [1]
Heavy tooth wear is commonly found on the occlusal (chewing) surface, but non-carious cervical lesions from tooth wear are also common in some populations. [7] Multiple indices have been developed in order to assess and record the degree of tooth wear, the earliest was that by Paul Broca. [8]
Classical restorative dentistry has traditionally followed the century-old approach of G. V. Black in classification and treatment of tooth decay.This was based on very limited knowledge at the time about the pathology of the underlying dental caries disease, and the need to specially prepare a cavity to repair a lesion (decayed area) with the limited available materials.
Graham J. Mount's classification: Mount classified cavities depending on their site and size. [ 11 ] The proposed classification was designed to simplify the identification of lesions and to define their complexity as they enlarge.
Diet plays a key role in the process of dental caries. The type of foods along with the frequency at which they are consumed can determine the risk for developing carious lesions. Infants and young children may consume fermentable carbohydrates, in the form of liquids such as: fruit juices, and soda pop. [1]
Periapical readiograph of lower right teeth, showing a large carious lesion in the distal of the lower right second molar. The same tooth also has an extensive periodontal defect. At this stage, without further information, it is difficult to tell which process has occurred first and lead to the death of the pulp.
Presence of carious lesion. Aesthetically unpleasant. Arresting the progression of the lesion. Reducing potential onset of caries or periodontal disease as these lesions can present as a plaque retention factor. Where there is a risk of pulpal exposure if lesion depth is severe enough. When retention of a removable appliance is interfered, i.e ...
