Brief summary

This study compared four mouth rinses/chews for their ability to reduce Streptococcus Mutans after usage. The four that were compared were chlorhexidine gluconate (0.12%), sodium fluoride (0.05%), paraffin wax chewing gum (sugar free), and deionized water. The paraffin wax chewing gum replaced the originally planned coconut oil and served as a placebo comparator.

Detailed description

The study was a randomized controlled clinical trial, unblinded. After obtaining consent and assent, respectively, and following review of medical history with regard to inclusion/exclusion criteria, if the participant met eligibility criteria, the participant was randomly assigned to one of four groups being studied: chlorhexidine gluconate (0.12%), sodium fluoride (0.05%), paraffin wax chewing gum (sugar-free) or deionized water with a randomization ratio of 1:1:1:1. A pre rinse/chew salivary sample was obtained by having the participant spit into a sterile test tube. The participant then either rinsed with 10mL of the assigned rinse for a timed 30 seconds and expectorated, or chewed paraffin wax chewing gum for 2 minutes. A post rinse/chew salivary sample was taken similarly to the pre rinse/chew sample. The samples were transported to a microbiology lab for incubation and quantitative analysis of Streptococcus Mutans. Morphological identification of the bacterial colonies was then confirmed using Matrix Assisted Laser Desorption/Ionization Time of Flight (MALDI-TOF) mass spectrometry.

Outcome results

Primary

Change in Salivary Streptococcus Mutans Levels After 30 Second Oral Rinse Time (Chlorhexidine Gluconate, Sodium Fluoride, or Deionized Water) or 2 Minute Chew Time (Paraffin Wax Chewing Gum)

Oral salivary sample obtained and plated on MSB (mitis salivarius-bacitracin) agar petri dish to determine Streptococcus mutans (S. mutans) levels. Values in each row in the Outcome Measure Data Table represent percentage change (increase denoted by positive number, decrease denoted by negative number) in S. mutans colonies from baseline (pre rinse/chew) sample for a single participant within that particular Arm/Group. Row titles have been arbitrarily identified as 'First Participant', 'Second Participant', 'Third Participant' and 'Fourth Participant.' No values are shown for 'Third Participant' and 'Fourth Participant' for the Chlorhexidine gluconate (0.12%) and Deionized water Arm/Group since only 2 participants were enrolled within each group. One result is obtained from each pre and post sample combination (percentage change).

Time frame: Sample obtained at baseline (pre rinse/chew) and immediately after treatment (post rinse/chew). Timed for 30 seconds (oral rinses) or 2 minutes (chewing gum)

Population: 1 pre (baseline) and post sample was collected and analyzed from each participant. As such, there were 2 pre and 2 post samples for the Chlorhexidine gluconate Arm/Group, 4 pre and 4 post samples for the Sodium Fluoride Arm/Group, 4 pre and 4 post samples for the Paraffin wax chewing gum Arm/Group, and 2 pre and 2 post samples for the Deionized water Arm/Group. Values in Outcome Measure Data table reflects percentage change (increase/decrease) in S. mutans colonies from pre (baseline) to post.
