Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Patients referred to the department of endodontics at Post Graduate Institute of Dental Sciences (PGIDS) Rohtak or any patient from routine opd requiring specialist endodontic consultation will be thoroughly examined .The examination will consist of a proper medical history and clinical examination, such as inspection, palpation, probing and percussion of the area of interest. When appropriate, additional tests such as sensitivity tests (cold and electric pulp tests) and conventional radiography will be performed. After the initial examination, patients judged to be in need of CBCT examination will be referred to the radiology department.
Stages of evaluation
Stage 1(before CBCT examination) Before referral, the examiner will write down the best available diagnosis and therapeutic plan using clinical examination and conventional radiography. The radiographs will be carefully viewed for periapical changes, vertical root fractures, internal or external resorption, perforation or any other radiographic finding.
Stage 2(after CBCT examination)
After the CBCT examination, the previous diagnosis and treatment plan will be considered and, if needed, a new diagnosis and treatment plan will be made by the same examiner, taking into consideration all of the data. The examiners will have access to all image reconstructions performed by the radiologist. These reconstructions will include images in the axial, coronal and sagittal planes throughout the entire volume.
Stage 3(patient dismissal) As per requirement therapy will be performed on the patients. The findings of orthograde treatment, explorative surgery, endodontic microsurgery, or extraction will serve as a gold standard for definitive clinical diagnosis.
Radiological investigation All intraoral periapical radiographs will be done with at least two angled (mesial and distal) views.
CBCT examination (Kodak CS 9300 Care Stream) done with exposure parameters 85 kilovolt and 5ma isotropic voxels with a size of 90\*90\*90 microns 5 \*5 cm volume FOV Slice thickness will vary from .9 to 1.3 mm.
The images will be viewed on a screen with a resolution of 1280\*1024pixels (Dell E19135).
Diagnostic decision making The diagnosis with periapical radiograph and CBCT will be made as per following choices
1. Healthy
2. Pulp necrosis
3. Apical periodontitis
4. External resorption
5. Root fracture
6. Non-endodontic diagnosis
7. Others
Therapeutic decision making
Treatment plans decided by radiographs and CBCT will be divided into following choices
1. No treatment
2. Wait and watch
3. Orthograde endodontics
4. Retrograde endodontics
5. Explorative surgery
6. Extraction
7. Referral to other specialist
8. Others

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
1. patients with symptomatic vital teeth otherwise judged healthy (no exposed dentin; normal sensitivity pulp tests; no tenderness to palpation or percussion; with radiographic apical/marginal periodontal normalcy; and no cracks/fractures)
2. patients with symptomatic root-filled teeth otherwise judged healthy (good quality of root filling that did not need to be revised or completed; no tenderness to palpation or percussion; with radiographic apical/marginal periodontal normalcy; and no cracks/fractures)
3. when conventional radiology failed to demonstrate if a finding was a pathological process or a normal anatomical structure.
2. Patients in which suspected disease had to be confirmed:
1. suspected dental fractures that could not be demonstrated
2. suspected external or internal resorptions.
3. As an aid in performing the therapeutic intervention:
1. in established external or internal resorptions to assist in the approach of complex cases
2. before apical surgery when important anatomical structures interfered with the surgical approach
3. in diagnosing foreign body structures, their location and, when needed, as a guide in the surgical removal
4. in understanding tooth anatomy of abnormal teeth in need of endodontic treatment
5. in assessing the number and location of root canals after at least one unsuccessful attempt to find them under oral microscope.
Exclusion Criteria
1. presented themselves with an accessible previous volume tomography in the region of interest. This was, however, not a strict restriction if the examiner judged that new and relevant information could be obtained by a new CBCT examination
2. had a definite diagnosis and treatment plan after a complete clinical and conventional radiographic examination and therefore did not need a CBCT examination. This group represented the vast majority of all patients
3. needed any other special imaging technique for soft tissue assessment such as CT or magnetic resonanace imaging.
