Rather, this is more greatly influenced by envi- ronmental factors like diet and oral hygiene habits. To understand exactly the role of genetics in the make-up of the oral microbiome, the research team conducted a twin study. They profiled the supragingival plaque microbiome of 205 pairs of genetically identical twins and 280 sets of non-identical twins between 5 and 11 years old based on mouth swabs. From this, they concluded that, while certain components of oral microbiome composition are influenced by genetic background, these inher- ited bacteria are not linked to dental caries.

According to article author Prof. Laurence James Walsh, from the Uni- versity of Queensland, dental pro- fessionals must be prepared for the sheer number of older patients, re- taining their natural teeth for longer. “A central tenet of modern preven- tive dentistry is to avoid intervening before prevention has been given a chance to work,” emphasised Walsh. “Protocols for oral care must be tai- lored to the patient’s needs and be re- alistic given the limitations in time, finance and energy which can be expended.” Particular problems in- clude root surface caries in pa- tients with a strong history of coro- nal caries and those who suddenly develop salivary hypofunction. Furthermore, elderly patients suf- fer from more chronic diseases. ihe presence of bacteria in the oral microbiome associated with dental caries is influenced more by environmental factors than genetic ones, the results of a new study have suggested. “There may be a perception in the community that bad teeth are inherited,” said study co-author Dr Jeff Craig, an associate professor at MCRI. “But this research is an im- portant message because it means parents and children themselves can take control. We’re not doomed by genetics in tooth decay.” The researchers also found that the level of inherited bacteria tended to decrease over time, whereas the bacteria associated with environmental factors in- creased. In light of these findings, Craig reiterated that limiting children’s intake of sugary foods and drinks, combined with a con- sistent oral hygiene routine, is the best way to prevent caries. The study, titled “Host ge- netic control of the oral microbi- ome in health and disease”, was published online on 13 Septem- ber in the Cell Host & Microbe journal. IV_Image_Anz_102z128_Layout 1 01.12.11 17:10 Seite 1 School bullying Verbal bullying at school can negatively impact an adolescent’s mental health, causing distress and anxiety. A Brazilian case-control study has now shown that this stress may be reflected in oral health too and possibly result in nocturnal bruxism. The cases were composed of 103 school pupils between the ages of 13 and 15 with possible sleep brux- ism (i.e. self- or parent-reported) and the controls of 206 adolescents without possible sleep bruxism. Among the participants, 134 (43.3 per cent) reported involvement in verbal school bullying episodes as a victim, perpetrator or both. The vast majority (90.3 per cent) of them were males. Overall, these teenagers were found to be four times as likely to suffer from sleep bruxism (65 per cent) compared with those who were not involved in verbal school bullying (17 per cent). ihe first-ever robot-led dental surgery was conducted in Xi’an in China in Septem- ber. In the 1-hour procedure, the robot independently placed two 3-D-printed im- ” NEWS Page 02 plants into the patient’s mouth. Sydney to host FDI 2021 Tweaking study results The Australian Dental Associa- tion (ADA) has announced that the FDI World Dental Congress will be held in Sydney in September 2021. “It is proof that Australia occupies an enviable place at the forefront of world dentistry and that this has, once again, been recognised by lead- ing figures in the world of dentistry,” ADA President Dr Hugo Sachs said. Researchers from Australia have found that more than a quar- ter of biomedical scientific papers may utilise practices that distort the interpretation of results or mis- lead readers—a practice known as “spin”. The highest, but also great- est, variability in the prevalence of spin was present in the clinical trials included in the review.
