Minimum age (years): 20
Maximum age (years): 60
Standard ages: ADULT
Accepts healthy volunteers: no
Observational model: OTHER
Time perspective: CROSS_SECTIONAL
Sampling method: PROBABILITY_SAMPLE
Study population: • CBCT of a sample of Egyptian subpopulation in Cairo governorate

Brief summary: to date there is no detailed examination of the root and root canal system of maxillary first and second premolars in an Egyptian subpopulation. in this study the investigators do an Observational analysis of available records of cone-beam computed tomography (CBCT) of root and canal morphology in the permanent maxillary first and second premolars in this population

Detailed description: Failure of endodontic treatment of upper first and second premolar because of presence of missed canals with lack of data of its morphological variations in the Egyptian population.There are different methods to study canal morphology as tooth clearing and root canal staining, conventional and digital radiographs, radiographic assessment enhanced with contrast media. Recently cone-beam computed tomographic (CBCT) images have been found to be useful in providing accurate anatomic details in 3 dimensions for diagnosis and treatment planning before endodontic therapy.

in this study the investigators do an Observational analysis of available records of cone-beam computed tomography (CBCT) of root and canal morphology in the permanent maxillary first and second premolars in this population

Eligibility criteria: Inclusion Criteria:

* CBCT scans with minimum of one premolar.
* Maxillary premolars with fully formed apices

Exclusion Criteria:

* CBCT scans with all maxillary premolars missed.
* Maxillary premolars with open apices
* Maxillary premolars with root resorption
* Maxillary premolars with calcifications or extensive coronal restoration.
* Maxillary premolars with root canal fillings, posts, crown restorations.
