Dental TribuneAsia Pacific Edition | 9/2015 02 By DTI KANNUR, India: A recent study has shown that oil pulling using coconut oil could be an effective method to reduce plaque formation and plaque- induced gingivitis. Coconut oil is an easily usable and safe substance with minimal side-effects and could thus becomeanalternativetoconventional oral antimicrobial agents such as chlorhexidine,thefindingssuggested. Thepilotstudyincluded60adoles- centsaged16–18withplaque-induced gingivitis, half of whom performed coconutoilpullinginadditiontotheir oral hygiene routine over the course of30days,whiletheremainderserved as a control group. The researchers observed a steady reduction in both plaque and gingival index values al- ready after one week of therapy. In addition,theynoteda50percentde- crease in these values in four weeks, which is comparable to the decrease producedbychlorhexidine. A number of studies have shown that oil pulling or swishing reduces gingivitis. In 2007, for example, oil pulling with sunflower oil was found to reduce plaque and gingival indices after 45 days. However, the current study is the first to investigate the benefitsofcoconutoilinthisrespect. To date, the mechanism by which oil pulling works is not fully under- stood. According to the researchers, its plaque-decreasing effect could be attributed to mechanical shear forces that can reduce adhesion of plaque. Another possible explanation is the compositionofcoconutoil.Itcontains 92 per cent saturated acids, approxi- mately 50 per cent of which is lauric acid, which has proven anti-inflam- matoryandantimicrobialeffects.

Coconut oil pulling reduces gingivitis By DTI DAVANGERE, India: Toothbrushes are prone to contamination by micro- organisms originating not only from the oral cavity but also from the sur- roundings in which they are stored. Indian researchers have now investi- gated how different dental disinfec- tantsaffectbacterialcolonisation. Inordertoinvestigatetheimpactof disinfectants such as chlorhexidine gluconate, sodium hypochlorite and wateronthepresenceofstreptococcal micro-organisms, the toothbrushes of 21 children aged 5–12 were evalu- ated after five consecutive days of twicedailytoothbrushing. Following the five-day trial, the brusheswereincubatedinRobertson’s cooked-meat broth for four to five hours before immerging them in the different disinfec- tants in groups of seven toothbrushes. Group 1 was immersed in 0.2% chlorhexidine, Group2in1%sodium hypochlorite, and Group3inwateronly. After 24 hours, all of the brushes were placed in Robertson’s cooked-meat broth again andthencultured. The final analyses showed that treatment with chlorhexidine re- sulted in a 100 per cent reduction of streptococci colonies, while sodium hypochlorite reduced the micro-or- ganismsby71percent.Incontrast,the tooth- brushesthatwereimmergedinwater only showed a 14 per cent reduction instreptococcicolonies. The results indicate that both chlorhexidineandsodiumhypochlo- rite are effective disinfecting agents. According to the researchers, the sig- nificantincreaseincontaminationof thetoothbrushesinGroup3suggests that rinsing one’s toothbrush only in water and air-drying could lead to toothbrushcontamination. In light of the findings, the resear- chers concluded that it is essential for every individual to disinfect his or her brush at regular inter- vals, hence preventing reinfection and help- ing maintain good oral hygiene and general well- being. Since the present approach did not consider all the vari- eties of micro- organismspres- ent in the oral cavity, future re- search should focus on the survival of other micro- organisms, such as other bacteria, fungi and viruses, the scientists stressed. Moreover, they noted that otherantimicrobialsolutions,suchas products of the neem plant or salt, might be economical, non-toxic and easy-to-usealternativesworthtesting fortheirdisinfectantproperties. Contaminated toothbrushes are associated with various oral health problems, including dental caries, gingivitis and stomatitis. Health or- ganisations,suchastheAmericaDen- tal Association, recommend chang- ing toothbrushes every two to three months. AD According to a recently published report by market research firm MarketsandMarkets, the global ortho- donticsuppliesmarketisexpectedto reach about US$3.9 billion by 2020, representing a compound annual growth rate of 6.9 per cent over the nextfiveyears.TheAsia-Pacificregion is expected to be the fastest growing market during the forecast period owing to constant health care ex- penditure and increasing awareness aboutorthodonticprocedures,among otherfactors. Overall, the growth in the ortho- dontic supplies market is primarily stimulatedbythegrowingnumberof patients with malocclusion, jaw dis- eases and tooth loss; technological advances;theincreasingpopularityof orthodontictreatmentamongadoles- centsandadults;andrisingdisposable incomesindevelopingcountries,such asIndia,ChinaandBrazil.Asreported byMarketsandMarkets,NorthAmerica is estimated to hold the largest share oftheorthodonticsuppliesmarketas of2015,followedbyEurope.
