Oral Alkali Production & Caries Prevention in Children (Longitudinal)

Status Completed

Clinical Trial Summary

The fact that dental caries remains a major public health problem mandates that oral-health researchers explore new strategies for assessment of caries risk, as well as for caries prevention and management. Dental caries occurs when acids produced by bacterial glycolysis of dietary carbohydrates causes demineralization of the tooth enamel. A major focus of caries research has been on identifying and characterizing acid-generating bacteria and the mechanisms of acid resistance. The purpose of this study is to investigate over time the relationship between alkali production and caries.

Clinical Trial Description

This study will require a total of 6 study visits over a 2 to 3 year period. The first study visit will last about one hour. At this study visit, parent-administered questionnaires will be used to collect information on the following: (a) the participant's demographic background (age, gender, and race), (b) socio-economic status (parents' income and housing condition), (c) participant's oral health practice (feeding histories, diet habits, oral hygiene measures, and dental attendance), and (d) systemic diseases. During the study visit, the participant's complete medical and dental history will be obtained and reviewed, and a dental exam will be performed in order to determine participants' caries status, and intraoral pictures may be taken of participants' teeth. At this visit and remaining visits participants will not be allowed to brush or clean teeth using any type of oral hygiene procedures for 8 hours prior to the visit. Saliva and plaque (the solf white-yellowish material on the tooth surface) will be collected at each visit. The Investigator will use a small probe to measure the pH of the dental plaque that builds up on the teeth. The participant will be asked to dip one finger into a glass containing a buffer solution and the probe will be placed on the teeth from which plaque will be taken. Plaque samples will be collected by gently scrapping the tooth using a sterile instrument. If the participant does not have enough plaque samples, they will be asked to return on the following day. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
