New research suggests 3-D photography could offer better orthodontic diagnosis using less radiation

first_imgCommon orthodontic problems such as crossbite, overbite, underbite, and crowding of the teeth can have a negative impact on a person’s physical appearance, dental function, and overall self esteem. To make a diagnosis and plan treatment, orthodontists currently take multiple x-ray images of the entire skull before, during and after orthodontic treatment. Part of the skull, the cranial base, is used as a stable reference for determining the position and orientation of the jaws and teeth when planning treatment changes. While the amount of radiation is small, x-rays of the whole skull taken multiple times during treatment can be a concern, especially for pediatric patients who are generally more susceptible to the harmful effects of ionizing radiation than adults.A recent study published in the European Journal of Orthodontics, suggests that another approach using non-radiographic 3-D dental photogrammetry could offer accurate dental and facial measurements based on using the eyes and natural head orientation as references rather than the cranial base.Mohamed Masoud, director of Orthodontics in the Department of Developmental Biology at the Harvard School of Dental Medicine, along with his research team studied 180 females and 200 males between the ages of 18 and 35 using 3-D facial and dental imaging to produce an adult sample with near ideal occlusion and a pleasing facial appearance. The goal was to provide reference values that can aid practitioners in determining the relative position and orientation of a patient’s dental and facial structures without exposing the cranium to radiation.

Syracuse bolsters attacking options to replace Raposo, Ferrin, Soerlie

first_imgThe Daily Orange is a nonprofit newsroom that receives no funding from Syracuse University. Consider donating today to support our mission.Syracuse advanced to the second round of the NCAA tournament in 2019 after earning an at-large bid, but the team was eliminated in a 2-1 loss to No. 16 St. John’s. The Orange struggled to string together consistent results, evident in their 2-4-2 conference record. Due to the Atlantic Coast Conference’s coronavirus schedule adjustments for 2020, Syracuse will play a shortened schedule with a minimum of six conference games. Here’s a complete breakdown of the Orange’s 2020 roster:Who’s gone The biggest question heading into the season is who will emerge as the Orange’s main offensive threat. Gone is All-ACC first-team forward Ryan Raposo, who was selected 4th overall in the MLS SuperDraft. Gone is attacking midfielder Massimo Ferrin, who played as SU’s second forward. And gone is forward Severin Soerlie, who graduated last year.AdvertisementThis is placeholder textRaposo’s 22 goal contributions (15 goals, seven assists) combined with Ferrin’s 16 (seven goals, nine assists) and Soerlie’s eight (four goals, four assists) mean that Syracuse will be replacing the vast majority of its attacking output this season. The trio scored 63% of the Orange’s goals last season. There will be significant turnover in the backline, too. If Syracuse continues to play its 3-5-2 formation, it will have to replace two of its starting defenders, wingback John-Austin Ricks and center back Nyal Higgins. Toronto FC selected Higgins as 19th overall in the MLS SuperDraft. Rotational defender Matt Orr and midfielder Brian Hawkins have also graduated. Who’s backSophomore forward Luther Archimede should be first in line to replace Raposo, but he’ll have to improve his scoring output and refrain from earning red cards. He only had two more goals (4) than red cards (2) last season. In midfield, the Orange have a lot of continuity outside of Ferrin. Versatile midfielder Hilli Goldhar, who mainly played at left wing in 2019, returns alongside fellow starters Amferny Sinclair — the NCAA’s 2019 leader in yellow cards — Julio Fulcar and Simon Triantafillou. Center back Sondre Norheim returns for his senior season with senior Dylan McDonald and sophomore Noah Singelmann. Starting keeper Christian Miesch, who kept five clean sheets in the regular season, will be in goal for Syracuse in 2020.  Who’s new Along with its annual recruiting class, Syracuse has replenished its squad with seven transfers, three of whom are graduate students.Matt McDonnell, a second team All-Patriot League selection in 2019 with Boston University, headlines the graduate transfers. McDonnell should immediately compete for playing time in a revamped Orange attack, while Max Kent (Macalester College) and Tim Ekpone (Pittsburgh) should bolster Syracuse’s defensive depth. The Orange added other attacking options with transfers Roque Viegas (Monroe College) and Manel Busquets (Duquesne). Viegas recorded 14 goals and 12 assists with Monroe in 2019, while Busquets was an All-Atlantic 10 first-team selection last season. Syracuse added eight freshmen in defenders Kyle Gruno, Stephen Betz, Jackson Glenn, Kenny Clapp, midfielders Tony Shaw, Jack Coleman and forward Deandre Kerr. Midfielder Jeorgio Kocevski, a graduate of Liverpool High School, is also part of the group. What to expectSU head coach Ian McIntyre needs to replace the scoring of Raposo and Ferrin, and he’ll likely rely on Archimede, McDonnell, Viegas and Busquets to share the goal-scoring burden. Any contributions from Kerr, a freshman, would be a bonus.Improvement from set pieces, alongside more goals from midfield, could help alleviate any early growing pains with Archimede, the only forward returning from 2019. Still, with a largely unchanged midfield and defense, Syracuse will likely be a solid, if unspectacular offensively, team in 2020.
