Objectives: This study purposed to examine the effect of mastic dentifrice in reducing dental plaque and oral
malodor, and to provide data to be used as basic and ground materials in developing mastic-containing commercial toothpaste and oral rinse.
Methods: From 150 volunteers, we excluded those who were under outpatient care for systemic disease and
those who had 23 or fewer natural teeth (with orthodontic extraction considered), and sampled 120 who participated in the research before the experiment and through 1, 2, 4, 8, and 12 weeks. For the subjects, we conducted oral examination and measured PMA Index, phase-contrast microscopy, oral malodor index, and Patient Hygiene Performance (PHP) Index each time.
Results: Oral PHP was lowered by the use of mastic dentifrice or the simultaneous use of mastic dentifrice and
oral rinse(p<0.05). Early gingivitis was eased by the use of mastic dentifrice or the simultaneous use of mastic dentifrice and oral rinse(p<0.05). Oral malodor was reduced by the use of mastic dentifrice or the simultaneous use of mastic dentifrice and oral rinse(p<0.05). The motility of bacilli, which are microorganisms causing periodontitis, decreased after 8 weeks in the group using mastic dentifrice only(p<0.05). As to change in the count and motility of microorganisms causing oral malodor, among oral microorganisms, filamentous microorganisms and spirochetes decreased differently according to the period of use between before the experiment and 12 weeks in the group using mastic dentifrice and the group using both mastic dentifrice and oral rinse(p<0.05).
Conclusion: In the results of experimenting on the antimicrobial effect of mastic against cariogenic bacteria and
periodontopathogens, when mastic dentifrice and oral rinse were used, the effect was different according to the period of use. Thus, it is recommended to apply the optimal period of use in order to maximize the effect of mastic in removing dental plaque and reducing/removing oral malodor. As a whole, it was concluded that the experimental dentifrice and oral rinse containing mastic contributed to the removal of dental plaque and the alleviation of early gingivitis.
