This process can occur internally, in the tooth pulp, or externally, affecting the enamel or cementum. The latter is more common. Occasionally, external root resorption may occur alongside internal resorption. resorption, based on X-ray microfocus-tomographical scanning of a case, which Key words: cervical resorption; external root will aid the dental practitioner in recognizing characteristic features during clin- resorption; peripheral inflammatory root On the outside of teeth, external resorption may look like deep holes or chips. Resorption affecting the roots of a tooth can be seen in X-rays as a shortening of the lengths of the roots and a The contributory factors implicated in external root resorption are periodontal infection, traumatic injury, orthodontic pressure, tooth bleaching and jaw cyst lesions [4, 15, 17].
3D The mean root (2012 Physiologic apical resorption—External surface resorption, transient apical resorption, and transient root resorption are terms previously used to describe normal physiologic response of the root surface to physiologic stimuli of the masticatory system, such as chewing pressure and muscle forces on the teeth. 6,14,15 It is found in most teeth, is part of the repair process to the cementum External resorptions associated with inflammation in marginal tissues present a difficult clinical situation. Many times, lesions are misdiagnosed and confused with caries and internal resorptions. A External resorption is “resorption initiated in the periodontium and initially affecting the external surfaces of the tooth—may be further classified as surface, inflammatory, or replacement, or by location as cervical, lateral, or apical; may or may not invade the dental pulpal space.”.
What external root resorption treatments work? The best external resorption treatments are those that take place in the earliest stages of the condition. In this case, an ounce of prevention really is worth a pound of cure.

Authors X-Ray Microtomography Unfortunately, once a lesion shows up as a dark spot on an X-ray, external resorption has already progressed. What external root resorption treatments work?
External resorption associated with orthodontics (braces) occurs at the tip of your tooth’s root, is typically minor in severity and self-limiting in the vast majority of cases. Cervical (up at the neck of your tooth’s root by the jawbone line) external resorption is treatable and can be resolved as long as it is caught early enough.

2 It can also be caused by a sudden injury (trauma following reimplantation) or persistence … X-ray examinations showed root resorption in the teeth involved in an odontogenic keratocyst.Root canal treatment with calcium hydroxide mixed with propylenglicol was performed. Furthermore, the use of varying X-ray angles has been suggested to distinguish internal resorption from external resorption and to locate the site of entry (Seward 1963). Because the pulp in the root canal is not involved in cervical external resorption, it is usually possible to clearly distinguish the radiopaque mineralized outline of the canal through the radiolucency of the external resorptive defect (Fig. 1).
