04 WORLD NEWS Dental Tribune Asia Pacific Edition | 1+2/2018 Study shows positive influence on dental caries using a multilevel approach By DTI SAN FRANCISCO, US: According to a new study, a multilevel approach that includes a dental caries risk as- sessment, aggressive preventive measures and conservative restora- tions can dramatically reduce caries incidence. The findings, which sup- port earlier research demonstrating positive results of the assessment and treatment method in a univer- sity setting, show that the protocol has the potential to transform den- tal care for high-risk patients. “We put the 2012 UCSF [Caries Management by Risk Assessment] clinical study into the real world and showed it works,” said lead author Dr. Peter Rechmann, Pro- AD www.idem-singapore.com 13 -15 APRIL 2018 SUNTEC SINGAPORE THE LEADING DENTAL EXHIBITION AND CONFERENCE IN ASIA PACIFIC THE BUSINESS OF DENTISTRY BUSINESS MATCHING Schedule your meetings with buyers, traders and distributors before you step foot into IDEM!

Those in the con- trol group also reduced their risk to a lesser degree, simply by using over-the-counter products that also protect teeth and affect the bacteria.” Caries Management by Risk Assessment (CAMBRA) is a method that was originally developed in 2003 by a team led by the Dean of the UCSF School of Dentistry Prof. John Featherstone. The method adopts a multilevel approach in which dentists collect patients’ dental and medical histories, con- duct clinical examinations to as- sess caries, and utilise behavioural approaches and chemical treat- ments to optimise protective fac- tors. For their two-year study, Rech- mann and his colleagues recruited 30 dentists to take part, 18 from private practices and three from community clinics. The study in- volved 460 patients aged between 12 and 65, split into two groups: the CAMBRA group and control group, with 239 and 221 partici- pants, respectively. In the CAMBRA group, high-risk patients received prescription fluoride toothpaste, a chlorhexidine antibacterial rinse, xylitol mints and a fluoride var- nish. The control group received regular fluoride toothpaste, an as- sumed inactive mouthrinse, sorbi- tol candies and a nonfluoride var- nish. In follow-up visits at six, 12, 18 and 24 months, new carious le- sions or changes in caries risk level were recorded. According to the re- sults, a significantly greater per- centage of high-risk participants were classified as lower risk after receiving CAMBRA preventive therapies. Dental caries was low in both groups. Among 242 patients (137 inter- vention, 105 control) initially iden- tified as high risk for caries, only a quarter of the patients remained at high risk in the CAMBRA group at 24 months, and just over half (54 per cent) in the control group. Of the 192 low-risk participants (93 intervention, 99 control), most participants remained low risk. The researchers believe this points to the assessment correctly identi- fying those at risk for caries. The study, titled “Changes in caries risk in a practice-based ran- domized controlled trial,” was published in the February issue of the Advances in Dental Research journal.
