Dental TribuneAsia Pacific Edition | 11/2015 ASIA PACIFIC NEWS 03 By DTI OTAGO,New Zealand: Dental decay is one of the most prevalent chronic diseases in New Zealand and the rest of the world. Now, researchers at the University of Otago have developed a new method that could help preserve caries-infected teeth and prolong the life of dental fillings in the future. While caries-inhibiting prod- ucts use silver that can cause significant discoloration of teeth, the new technology uses specif- ically formulated, non-staining silver particles to arrest caries and render teeth more resistant to decay. According to the re- searchers, the product has to be applied after caries removal but before filling. It diffuses into the tooth, where it can kill remaining bacteria that may cause further decay. “We believe that our non-stain- ing formula will be an important step forward for oral care and pub- lic health,” said Dr Don Schwass, senior lecturer and prosthodontist at the university’s Department of OralRehabilitation.“Theresultwill be that recurrent caries will be sig- nificantly reduced and dental fill- ingswilllastlonger,providingboth economic and health benefits.” Otago Innovation, the univer- sity’s technology transfer office, has recently licensed the rights to this formula to a global dental ma- terials manufacturer for further product development.

A wide- scale review conducted by clinicians from the Melaka Manipal Medical College’s Department of Dentistry in Melaka and published by the Cochrane Oral Health Group in Manchester has recently found no evidencethatanyofthesestrategies areineffectiveatpreventingorman- agingthecondition. After a search for randomised clinical trials evaluating strategies for managing the gag reflex, the researchers only found one study, from Brazil, on the effects of acupuncture at Point P6 versus placebo acupuncture, to be eligible forthereview.Oftheother256stud- ies they took into consideration, none qualified to be included in the paperowingtobias,irrelevanceand severalotherreasons. For their review, the Malay re- searchersconsultedCochrane’sreg- istration database and other med- ical search engines for clinical trials spanning from 1980 to the present day. Owing to the inconclusive re- sults,theyrecommendedthatmore studies be conducted on both phar- macologicalandnon-pharmacolog- ical interventions, with special em- phasisonbehaviouralmodification techniques. Future research should alsotakeintoaccountamorevaried population range and factors such aspatientsatisfaction,theystated. Moreover, more comparable studies are needed in contrast to only trials involving a dummy or aplacebotechnique. Although little is known about its prevalence, an exaggerated gag reflex during dental treatment is a problem encountered by many dental practitioners, often during denturetry-insessions.Theresponse can be triggered by a variety of pro- cedures, including third molar re- movalorintra-oralimagetaking.
