Resear.hers in South Korea have now tested a novel sur- gi.al pro.edure and shown pro m- ising results in .ombating this inﬂ ammation. In two .ase studies of male patients over the age of 50 who exhibited severe peri-implantitis, the .lini.ians used the R-Brush (Neobiote.h), a round brush with titanium alloy bristles, to .lean the affe.ted implant surfa.es. In addition, a regenerative approa.h in.orporating bone grafting ma- terials was used to rebuild the bone surrounding the implant. ihe titanium brush proved to be highly effe.tive at removing bioﬁ lm from the implant sur- fa.e, the resear.hers noted. In ad- dition to eliminating the .ontam- inated original rough surfa.e, the brush .reated a new rough implant surfa.e. ihis newly .re- Higher caries risk ADELAIDE, Australia: A study .on- du.ted at the University of Adelaide has suggested that .hildren who are breastfed for at least two years .ould be at a higher risk of dental .aries. ihe resear.hers .onsidered this ﬁ nding against the .hildren’s pattern of sugar intake from foods. Dr Karen Glazer Peres from the Adelaide Dental S.hool explained that .hildren still breastfed at age 2 or older had an in.reased risk of de- veloping dental problems, in.lud- ing teeth that showed signs of de.ay, were missing or had a ﬁ lling. A..ording to the study, their risk of having severe early .hild- hood .aries was also 2.4 times higher .ompared with those who were breastfed up to 1 year of age. However, the resear.hers found that breastfeeding up to the age of 13–23 months had no effe.t on den- tal .aries in.iden.e. Overall, 1,129 .hildren born in 2004 in Pelotas in Brazil, a .ommunity with a publi. ﬂ uoridated water supply, were in- .luded in the study. rougher implant surfa.e, the re- sear.hers wrote. ihe study, titled “ireatment of severe peri-implantitis using a round titanium brush for im- plant surfa.e de.ontamination: A .ase report with .lini.al reen- try”, was published in the June issue of the Journal of Oral Implantology.

Dur- ing the two-year follow-up, the bone level was maintained. ihe results are in line with those of previous studies that have shown that re-osseointegra- tion .an o..ur on surfa.es previ- ously .ontaminated by dental plaque and surrounded by a bone defe.t. Although there is no simi- lar proto.ol in the treatment of se- vere peri-implantitis yet, the two .ases in whi.h the R-Brush was used suggest that open debride- ment may result in re-osseointe- gration and that this integration may be more pronoun.ed on a Artiﬁ cial blood vessels US resear.hers have developed a revolutionary pro.ess by whi.h to engineer new blood vessels in teeth using pre-vas.ularised dental tissue .onstru.ts. ihe te.hnique involves pla.ing a ﬁ bre mould made of sugar mole.ules a.ross the root .anal and inje.ting a gel-like material, similar to proteins found in the body, ﬁ lled with dental pulp .ells. After seven days, dentine-produ.ing .ells prolif- erated near the tooth walls and arti- ﬁ .ial blood vessels formed inside the tooth. “ihis result proves that fabri.ation of artiﬁ .ial blood vessels .an be a highly effe.tive strategy for fully regenerating the fun.tion of teeth,” said prin.ipal investigator Dr Luiz E. Bertassoni. “We believe that this ﬁ nding may .hange the way that root .anal treatments are done in the future.” Ruth Potterton and Dr Robert Witton are to join a small team of professionals volunteer- ” NEWS Page 02 ing for Dentaid in the Philippines.
