Assess Needs: Fill & Download for Free

If you look at medieval skulls one of the thing you’ll notice is that many people had a very good alignment with both molars and incisors matching each other on the bite. Overbites did exist and its not likely everyone had perfect teeth but very few would have needed braces to get the typical Hollywood smile.Modern orthodontists looked at ancient skulls to determine what kind of treatment they would get if they were alive today.Only 36% of the medieval group showed objective assessed needs for orthodontic treatment, compared with 65% of the present-day sample. Among the skulls, the objective needs for treatment were 27% for the males and 49% for the females. No sex differences related to severity or prevalence of malocclusion were found in the modern sample. The medieval sample arranged according to severity was great need (B), 7%; obvious need (C), 29%; and little/no need (D/E), 64%. The findings in the modern sample were B, 20%; C, 44%; and D/E, 35%. The female skulls showed greater severity and prevalence than the male skulls. No skull had very great need (A). Conclusions: This study indicates a significant increase in both the prevalence and the severity of malocclusions during the last 400 to 700 years in Oslo, Norway. Furthermore, although no sex differences were found in the modern sample, females had both a higher prevalence of malocclusions and more severe malocclusions than did males in the past. - Are malocclusions more prevalent and severe now? A comparative study of medieval skulls from NorwayBesides this many had a jaw that could accommodate the wisdom teeth without it impacting. Then there’s the fact that the majority of people with impacted wisdom teeth have no complications arising from it and certainly not to the age most people were dead in the Middle Ages.Taking out the third molar as a prophylactic against future issues has only been a routine procedure since we’ve figured out local anesthetics to aid in the procedure. Before that people just left them in until they actually started to cause trouble.People who did experience issues with their wisdom teeth either lived with the pain or had them extracted without anesthesia.A strong arm and pliers that went by names such as toothkey or pelican were the instruments of torture.Now if I made it sound like all was good an well in the past I should you remind you that death by dental infection was not unheard of in the past.
