Dental TribuneAsia Pacific Edition | 11/2015 02 ASIA PACIFIC NEWS By DTI KYOTO, Japan: Although some stud- ies have suggested an association between second-hand smoke and caries, it is still uncertain whether reducing passive smoking among children would contribute to caries prevention. However, a Japanese studyhasnowfoundthatinfantsex- posedtosmokingat4monthsofage showedanincreasedriskoftoothde- cay at age 3 compared with children fromasmoke-freefamily. Researchers from the Graduate SchoolofMedicineandPublicHealth atKyotoUniversityanalyseddatafor 76,920 children born between 2004 and2010.Allofthechildrenattended routine health check-ups at 0, 4, 9 and 18 months and at 3 years of age. Information on second-hand smoke exposure from pregnancy to 3 years ofageandotherlifestylefactors,such as dietary habits and oral care, was obtainedthroughquestionnaires. The findings showed that 55.3 per cent of children in the study were exposed to second-hand smoke by family members in the household at 4 months and 6.8 per cent had evidenceoftobaccosmokeexposure. The latter was defined as smoking in frontoftheinfantbytheresearchers. Overall, 12,729 incidents of dental caries, mostly decayed teeth, were foundinthestudygroup. Comparedwithhavingnosmoker in the family, exposure to tobacco smoke at 4 months of age was asso- ciated with an approximately two- fold increased risk of caries at age 3. The risk of caries was also increased among those children exposed to household smoking, whereas the effect of maternal smoking during pregnancy was not statistically sig- nificant. Although these findings cannot establish causality, they support extending public health and clini- cal interventions to reduce second- hand smoke, the researchers con- cluded. Health statistics show that the levelofdentalcariesinprimaryden- tition remains high in developed countries. In Japan, one-fourth of all 3-year-old children experience caries, whereas 20.5 per cent of chil- dren aged 2 to 5 are affected in the US,accordingtotheresearchers. The study, titled “Secondhand smokeandincidenceofdentalcaries in deciduous teeth among children in Japan: Population based retro- spective cohort study”, was pub- lishedon21OctoberinTheBMJ.

Second-hand smoke increases risk of tooth decay in children CAPP Managing Director Dr Dobrina Mollova remarked that the growth of CAD/CAM dentistry alongside new technology, materi- als and equipment has seen rapid integration into dental offices and laboratories. “Without a doubt, digital technol- ogy is becoming essential for every dental practice and laboratory,” she said. “The question is: are we pre- pared to keep up to date with this growing industry, and are we able to implementthispoolofinformation in our practices without the proper expertise? This will be the main challengeforus.” A spin-off of CAPP’s event series in Dubai, the CAD/CAM and Digital Dentistry International Conference was first held in Singapore in 2012. Over 400 dental professionals at- tended the last edition, which took place at the Marina Bay Sands hotel twoyearsago.
