Arms Assigned Interventions
Experimental: sugar substituted chewing gum A Dietary Supplement: casein phosphopeptide amorphous calcium phosphate complex
two pieces of the commercial presentation three times daily after meals
Other Name: CPP-ACP complex
Experimental: Sugar substituted chewing gum B Dietary Supplement: xylitol
6 g/day, for a month, by chewing 2g three times daily after meals.
Other Name: sugar alcohol

Detailed Description:

The purpose of this paper is to compare the effect of daily consumption of two sugar-free chewing gum, one with Recaldent and one with Xylitol, added to traditional hygiene (brushing, fluoridated toothpaste and dental floss), in clinical features such as the accumulation of plaque and gingival inflammation, microbiological characteristics of saliva as the counts of cariogenic microorganisms and facultative anaerobes, and some physicochemical properties of saliva such as pH and concentrations of calcium and inorganic phosphate.

To this there was a general call among dental students at the University of Antioquia and those who expressed their intention to participate voluntarily with informed consent, were examined clinically and randomly assigned to one of the study groups (Recaldent or Xylitol) or the control group.

After a month of baseline examination and the daily use of the same instruments of oral hygiene and chewing of 6 pellets of each chewing gum (in the case of study groups), all variables are re-examined.
