The study looked at 83 children with hypodontia—defined in the study as the developmental ab- sence of up to five permanent teeth—and compared them with 253 children without the condi- tion. The children’s mothers re- ported their levels of exposure to active and passive smoking dur- ing pregnancy, along with their caffeine and alcohol intake. Prof. Mauro Farella, who led the research, said that hypodontia was positively linked to cigarette smoking. The study found no as- sociation between the condition and drinking alcohol or caffein- ated drinks however. bacco,” said Farella, who is head of orthodontics at the University of Otago’s Faculty of Dentistry. “The more cigarettes a mother reported smoking during pregnancy, the greater the likelihood was of her child having hypodontia.” “There was a suggestion of a ‘biological gradient’ effect with to- “Though more research is needed to confirm the association we found between maternal smoking and the condition, a plausible explanation is that smoking causes direct damage to neural crest cells in developing embryos,” he explained. The findings are in line with a growing body of evidence that demonstrates the negative impact Facial features Researchers in the US have found that genetics that shape dental and thus facial features might also in- crease the likelihood of specific hand- edness. In a recently published study, people with slender faces were found to be predominantly left- rather than right-handed. The findings of the study were based on three national health surveys, with a total of 13,536 participants, that were conducted in the US in the 1960s and 1970s. In a review of these, researchers at the University of Washington School of Dentistry found that bilateral retro- gnathism—the dental marker for a convex facial profile, slender jaws and overbite—was associated with 25 per cent increased odds for left- handedness in the study popula- tion. They further stated that prev- alence of bilateral retrognathism in all three surveys was significantly higher among European Americans than African Americans.

MELBOURNE, Australia: For the first time in the Osteology Foundation’s history, Melbourne played host to one of the three Asia-Pacific symposiums in 2017. Themed “Strategies for predict- able regeneration—Today and tomorrow”, the scientific pro- gramme delved intensively into the current status of knowledge and research in oral tissue regeneration, discussing new trends and techniques in the field. Held on 2 and 3 June at the Ar- thur Streeton Auditorium in Mel- bourne, the two-day event was one of four symposiums taking place over the next 12 months. Other host countries are Japan, China and Russia. In addition to such national events, the non- profit organisation holds its inter- national symposium in the Côte d’Azur in Monaco every three years. smoking while pregnant can have on an unborn baby. Various studies have shown that smoking during pregnancy increases the risk of pre- mature birth, a low birth weight or a stillbirth. The study, titled “Mater- nal smoking during pregnancy is associated with offspring hypodon- tia”, was published online on 23 May in the Journal of Dental Research.
