Changes in the epidemiology and aetiology of dental traumatic injuries in permanent teeth in children before and after German unification.

AIM: To evaluate the longitudinal occurrence of traumatic dental injuries in permanent teeth comparing recent data from 2014 to 2016 in Greifswald after German unification with a historic sample from socialist times (1974-1989). MATERIALS AND METHODS: In this retrospective study, traumatic dental injury parameters as type, date, location, and cause of injury as well as tooth affected were extracted from the trauma records of patients from 1974 to 1989 and 2014-2016. RESULTS: The descriptive analysis of 444 teeth in 245 patients revealed that the recent and historic samples had a very similar pattern of dental trauma (201/243 teeth in 117/128 patients, respectively): Maxillary permanent central incisors were affected in 70.7% and 68.3%, respectively. Enamel-dentine fractures were the most prevalent fracture injury in both recent and historic samples (64% and 43.1%, respectively) followed by enamel fractures (20.7% and 36.9%, respectively). Subluxations were the most common luxation traumatic dental injury (44.7%) followed by lateral luxation (39.8%) as reported in the historic sample while in the recent sample subluxation constituted 42.9% of luxation injuries followed by concussion (36.2%). CONCLUSION: This study detected a very stable pattern of dental traumatic injuries over 40 years, even after the change from a socialistic society to a market economy.

Forty years of national surveys: An overview of children's dental health from 1973-2013.

INTRODUCTION: The first national survey of children's dental health in England and Wales was carried out in 1973. Subsequent surveys, in 1983, 1993 and 2003, included all United Kingdom health departments. The 2013 survey involved England, Wales and Northern Ireland. AIM: To consider all five surveys, from 1973 to 2013, so as to summarise trends in the dental health of children in the UK over the last 40 years. MATERIALS AND METHOD: The 2013 survey was commissioned by the Health &Social Care Information Centre and all surveys used data collected during dental examinations conducted in schools on a random sample of children by NHS dentists, together with a questionnaire to parents of those children. In 2013, a pupil questionnaire for 12- and 15-year-olds was introduced, to complement information received from parents and carers. RESULTS: A total of 69,318 children, aged 5-15 years, were involved, from 1973-2013. Caries prevalence has reduced from 72% to 41% in 5-year-olds, and from 97% to 46% in 15-year-olds in 40 years. Changes in periodontal disease, orthodontic treatment, accidental damage to anterior teeth, tooth surface loss and enamel defects, are also summarised. Behavioural and attitudinal characteristics observed in the 2013 report are listed. CONCLUSIONS: Caries is now concentrated in a minority of children. The prevalence of gingivitis has not changed a great deal in 40 years. About half of those children assessed 'in orthodontic need' receive treatment.

History of the Dental Trauma Guide.

The history of the Dental Trauma Guide dates back to 1965, where guidelines were developed for trauma records and treatment of various trauma entities at the Department of Oral and Maxillofacial Surgery at the University Hospital in Copenhagen. In 1972, a unique possibility came up at the Serum Institute in Copenhagen to test various dental trauma procedures in monkeys, which served as kidney donors in the polio vaccine production. Over the years, 40 000 dental trauma patients were treated at the Trauma Centre according to established guidelines, and 4000 of these have been enrolled in long-term follow-up of various trauma entities. This has resulted in 79 clinical studies, and 64 studies in monkeys have examined the effect of various treatment procedures and the aetiology of most healing complications.

Most of the external forces hitting the body (automobile injuries, sport injuries, job accidents, falls, hits and fights) reach the head, and especially the oral and maxillofacial region. Statistics show the head is injured in more than 70 per cent of car accidents. The incidence of head injuries, specifically tooth injuries, is high among both infancy and school children. Authors give a review about the changing approaches of treatment principles in the reports published in the Hungarian dental journal 'Fogorvosi Szemle' in the past 100 years, and how today's modern treatment trends have evolved.

Dental mutilation in southern African history and prehistory with special reference to the "Cape Flats Smile".

Southern Africa has a long history of dental mutilation in the form of dental chipping and of intentional removal of anterior teeth. The first evidence is found in the skeletons of Early Iron Age populations (ca. 1500 years before present), but the incidence decreases in archaeological sites of more recent origin. In modern times, dental mutilation appears to have been limited to the people of the countries further north in Africa, but the one exception is the presence of deliberate incisor removal amongst the communities of the Western Cape. It is hypothesised in this paper that the modern practice in the Cape is associated with youthful gangs in the poorer communities, and acts as part of a rite of passage into adulthood. The "socio-sexual" theory, as reflected in such names as the "passion gap", is shown to be both wrong and insulting. The name "Cape Flats Smile" is recommended as a more appropriate and respectful term for the phenomenon.
