Introduction

Most of the clinical decisions are majorly influenced by information from diagnostic in a more directly. Best treatments are achieved when accurate data, planning decisions and highly predictable outcomes are also achieved when such data are accurately collected and analyzed. The need to have a more innovative technology to offer information on clinical relevance of the required data has led to the introduction of Cone beam computed tomography (CBCT). The new technology has been intended to solve the problem that could not be done by conventional radiography. Superimposition that is found within the conventional radiographic has been eliminated by the capability of assessing a specific area that interest 3 dimensions (3-D). Images that have objects that are superimposed on one another are usually produced by intraoral radiography. By use of a 2-D film, observers are able to make decision on 3-D. the greatest advantage of CBCT is the fact that it can offer clinicians the ability to clearly observe particular area in three planes that are different, known as sagittal, axial, and coronal as such, 3-D information is acquired. Sagittal and axial views are usually used for particular value and are normally not seen with conventional periapical radiography. CBCT is superior when compared by the conventional periapical radiography and this is a result of the ability to reduce or completely do away with superimposition of the structure. When the technology in use becomes more prevalent, CBCT applications, such as endodontic, are easily identified. Diagnosis of canal morphology and endodontic pathosis, assessing pathosis of a non-endodontic, analyzing of the internal and external root resorption, among many other form the application of potential endodontic. Treating root resorptions (RR) is usually a very complex and misdiagnosed. It is very crucial to have imaging to enhance diagnosis and a much more appropriate treatment. The description given to radiographic features of both the internal and external resorptions was done by a number of scholars. Off-angle radiographs have proved the differentiation of these entities. Technique such as parallel radiographic has been very instrumental in differentiating external resorption from internal resorption defects. Resorptive lesion nature is always confirmed by taking second radiograph in different position. When dealing with internal RRs, the position as per the canal of the radiographs should remain the same. According to radiological, internal resorption is presented as mottled, cloudy, and radiopaque lesion that have margins that are not regular. It is because of hard tissue deposits of metaplastic found within the canal space. There are always some difficulties in a clinical differentiation internal resorption from external resoprtion more so, when the entire resorptive captivity is has been occupied with metaplasia. The accuracy on the diagnostic relies on the examination by the radio graphic and conventional as are limited by the fact that produced images only give a 2-diamentional representation and that of 3-D. There is high chances that the images of the atomic structures are likely to be distorted, which can possibly promote misdiagnosis and result to incorrect treatment when managing internal as well external root resorptions. This paper will not dwell much on external resorption but on internal resorption. Internal root resorption was reported in the early times of 1830. Internal root resorption is a rare thing when compared to that of external root resorption. There is no clear literature that describes the etiology and pathogenesis of internal root resortiptions as does to external. It is therefore not very easy to understand etiology or even the pathogenesis of internal resoprtion. The major reason that has resulted to the clinical concern in the internal root resorption is its similarity with the external cervical resorption. If not properly examined, there may be a case such as incorrect diagnosis resulting from inappropriate treatment in particular cases. Clinicians can only perform decisions that involve prognosis of the tooth after the resorption of the internal root is diagnosed. When the diagnosis is done and the tooth found to be restorable and at the same time has reasonable prognosis then the canal treatment is considered treatment of choice. Treatment for root canalis aimed at ensuring that no any remaining necrotic coronal portion, apical tissue, and important tissues that may trigger resorbing cells through blood supply and disinfect have the root canal system obturate. There are unique difficulties when preparing and in the obturations on the tooth that is affected as presented by the international RR lesions. In the access of the cavity, preparation need to be conservative and highly preservative of as many tooth strictures as much as possible and ensure that there is no more weakening of tooth that is already compromised. While beginning chemomechanical debridement, teeth that has active resorbing lesions, granulation tissues, and bleeding that comes from pulpal that is inflamed may end up impairing the visibility. In normal cases, reasorption defects shape is what gives the inaccessibility to mechanical instrumentation directly. In treating root canal, the main objective is disinfecting root canal system. That step is usually followed by obturation of those disinfected can using appropriate root-filing things that will ensure that reinfection does not occur. It is normally very difficult to adequately obdurate internal RR defects by its very nature. It is required that the material use in obturation be flowable to ensure that resorptive defect is completely sealed. One of the mostly used as a filling material during endodontics is referred to as Gutta-percha. There are scholars who went ahead to examine the worth of root filling particularly in the teeth with artificially manufactured internal resorption cavities.
