Assessment of Salivary Bacterial Level and Dental Caries Experience in a Group of Egyptian Children With Black Stained Teeth

• Conditions: Black Stain Dental, Dental Black Stain, Black Stain*, Black Stains, Tooth Stains

• Registration Number: NCT03563469
• Lead Sponsor: Cairo University

Brief Summary

Black stains (BS) are type of extrinsic discoloration of the tooth. It's characterized as dark lines or an incomplete coalescence of dark dots found mostly on cervical third of the crown. Most studies worldwide found that children with the black stained teeth have low caries prevalence. A study on Brazilian population also suggested that black stains might be protective factor against development of dental caries. A study reported that chromogenic bacteria were proposed as etiological factor in production of black stains.The most common microbiological composition of BS was found to be Actinomycetes. Dental examination and saliva samples collection will be done for black stained teeth children of outpatient clinic of Pediatric Dentistry and Dental Public Health Department, Faculty of Dentistry, Cairo University. This research adopts null hypothesis; it assumes that there is no effect on dental caries experience in children with black stained teeth.

Primary Outcome Measures

Name	Time	Method
Salivary bacterial level	6 months	salivary sample collection by passive drooling

Secondary Outcome Measures

Name	Time	Method
Dental caries experience	6 months	The dental caries of all patients will also be recorded using dental mirror and explorer. The caries experience will be recorded in diagnostic chart using the World Health Organization (WHO) criteria for deciduous teeth and dmft caries index
Salivary pH level	6 months	salivary sample collection and measured by the pH meter
