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.

Conditions

Black Stain Dental, Dental Black Stain, Black Stain*, Black Stains, Tooth Stains

Study Design

• Observational Model Type: CASE_ONLY
• Study Time Perspective: CROSS_SECTIONAL

Interventions

Salivary bacterial and pH level

1. Saliva sample will be collection ask the patient to stop eating and drinking for one hour before collecting the sample,(2) Give the patient distilled water and ask them to rinse their mouth well for 1 min,five minutes after this oral rinse, ask the patient to spit into 50ml sterile tube, collect 5ml of saliva and return to the laboratory within an hour.

2. 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.

Intervention Type: OTHER

Other Intervention Names

Dental caries experience using dmft caries index
