C-shaped Root Canal Prevalence and Configurations in Egyptians

NCT03635203 | Unknown

• 1 other identifier: C-shaped_root_canal
• Study Type: observational
• Target: 374
• Locations: 1 country
• Sites: 1

Brief Summary

The aim of this study is to investigate the prevalence and configuration of C-shaped root canal of mandibular first and second molars among members of an Egyptian sub-population using cone beam computed tomography (CBCT). The prevalence and distribution of the C-shape canal configurations with respect to gender and age will be also investigated. Data regarding the prevalence and configurations of C-shaped root canal in the first and the second mandibular molars in Egyptian sub-population is lacking which might affect the correct implementation of chemo-mechanical instrumentation and obturation.

Conditions

Keywords

C-shaped root canal / C-shaped canals

Outcome Measures

Primary Outcomes (1)

• Prevalence of C-shaped root canal in the whole sample

  Using CBCT / Binary system (Yes/No)

  Immediately

Secondary Outcomes (1)

• Configurations of C-shaped canals of mandibular first and second molars in the whole sample

  Immediately

Interventions

CBCT DEVICE

Observation of C-shaped root canal in mandibular first and second molars in Egyptian sub-population

Also known as: Cone beam computed tomography

Eligibility Criteria

• Age: 15 Years - 70 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

1. The data collection will be obtained from the data base available at a private radiographic center (oral and maxillofacial imaging center located in Cairo, Egypt). 2. CBCT images will be obtained from Egyptian patients who had CBCT examination as part of their dental examination including diagnosis, treatment planning and follow-up during the years before 2015.

You may qualify if:

• CBCT images of good quality at which the mandibular first and second molars could be seen adequately.
• Mandibular first and second molars with fully developed roots.

You may not qualify if:

• Tomographic images of poor quality or artifacts interfering with the detection of the root canals
• Tomographic images without demographic data including gender and age of the patient
• Mandibular first and second molars having:
• coronal fillings or deep caries reaching the pulp floor
• root caries specially reaching the bifurcation area or root fracture
• external or internal root resorption
• root canal calcification or a periapical lesion (s)
• previous root canal treatment
• post or crown restoration
• evidence of apicectomy or periapical surgery.
• developmental anomalies.
