Pre-eruptive intracoronal resorption as an entity of occult caries.
نویسنده
چکیده
"Occult" or "hidden" caries refers to occlusal caries which is not diagnosed clinically because the occlusal surface appears ostensibly intact, and radiographs show radiolucencies in dentin. The prevalence of occult caries has been reported to range from 2.2% to over 50% of permanent molars. In spite of its relatively high prevalence, the etiology and pathogenesis of occult caries remain unclear. The author hypothesizes that occult lesions could have resulted from processes which are pre-eruptive or post-eruptive. Pre-eruptive processes include intracoronal resorption of unerupted teeth, and the post-eruptive process is occlusal fissure caries. Although the prevalence of intracoronal resorption has been shown to be around 3-6% by subject and 0.5-2% by teeth, the percentage contribution of this process to the overall prevalence of occult caries is unclear. When affected teeth are fully erupted, it is difficult to determine if pre-eruptive resorption had been present previously. The prevalence of occult lesions does not appear to be affected by fluoride exposure. Radiographs are useful adjuncts to aid in the diagnosis of occult lesions. Bitewing radiographs are useful for detecting early occlusal fissure caries while panorex radiographs of unerupted developing teeth aid in the diagnosis of pre-eruptive intracoronal lesions. It is suggested that all unerupted, developing teeth on radiographs be examined for pre-eruptive resorptive lesions.

Pre-Eruptive Intracronal Resorbtion at Unerupted Three Molar Teeth: A Case Report
Pre-Eruptive Intracronal Radiolucency (PEIR) is seen as a radiolucent anomaly at coronal dentin of unerupted teeth. PEIR is often confused because of similarities with dental caries. Pre-eruptive intracoronal resorptions are typically observed as radiolucency in dentin tissue, and the lesions are close to the enamel dentin junction. Lesions are often coincidentally noticed on the radiographs of...
متن کاملTreatment of severe pre-eruptive intracoronal resorption of a permanent second molar.
Pre-eruptive intracoronal resorption is a lesion often located within the dentin, adjacent to the dentin-enamel junction, in the occlusal aspect of the crown. As the lesions resemble caries, they are often referred as "pre-eruptive caries." The purpose of this case report was to describe the diagnosis and treatment of a permanent molar with pre-eruptive intracoronal resorption and to elaborate ...
