– The aim of this study was to investigate pre‐injury factors, causes of dental injuries and healing complications after traumatic injuries to permanent teeth. The analysed sample comprised 889 ...permanent teeth of 384 patients, who were treated in the Dentistry Department in Faculty Hospital in Pilsen. Enamel‐dentin fractures 233 teeth (26.2%) and lateral luxations 207 teeth (23.3%) were the most frequent injuries. The age of the patients at the time of injury varied between 7 and 65 years. Predominantly, children were affected 587 injured teeth (66.0%). The most frequent causes of injuries in patients older than 11 years were various sport activities, predominantly bicycling. Pulp necrosis was observed in 239 teeth (26.9%). It was the most frequent post‐traumatic complication in all types of dental traumas. Teeth with a completed root formation demonstrated a higher prevalence of pulp necrosis than teeth with an incomplete root formation in all types of luxation injuries. External root resorption was observed in 144 teeth. The rate of inflammatory resorption differed between the various types of luxation injuries (extrusive luxation 5.6%, lateral luxation 11.6%, intrusive luxation 33.3%). Following avulsion and replantation, active inflammatory resorptions were diagnosed in 13 (26.5%) of 49 replanted teeth and ankylosis/replacement resorptions were observed in 21 (42.9%) of 49 replanted teeth. After avulsion, primarily, immature teeth were affected by these complications. Within the observation period of 5 years, 39 teeth (4.4%) had to be removed (16 teeth with root fractures, 19 avulsed and replanted teeth, 3 luxated teeth, 1 tooth with crown‐root fracture).
– Dental injuries are rather common during sport activities and at schools where children spend most of their time every day. The purpose of this study was to evaluate the knowledge of primary ...school teachers in Pilsen, Czech Republic, of how to provide first aid in cases of one of the most serious dental injuries, the tooth avulsion. To this end, a questionnaire which contained nine questions about avulsion of permanent teeth was prepared. The questionnaires were distributed in nine primary schools in Pilsen where almost 300 teachers are employed. Seventy‐four percent of the teachers replied. Sixty‐eight percent had never received any information about providing first aid in cases of dental injuries and 81% would place the avulsed tooth in a dry handkerchief until the transfer of the patient to dentist. Prevention of tooth injuries is very important, as they may result even in tooth loss. This demands an effort to properly inform and educate sport trainers and primary school teachers about providing first aid in dental trauma situations; this effort should be intensive and continuous.
– The aim of this study was to find out the causes that lead to dental avulsion in children, to analyze the effectiveness of our treatment and the response of the adults when such incidents occur ...and finally to determine the occurrence of posttraumatic complications some time after the injury, especially the resorption of the affected teeth root. We analyzed the documentations of a sample of patients containing 57 children who had a total of 90 avulsed teeth and were treated in Dentistry Department of Medical Faculty in Pilsen, Czech Republic, in the years between 1995 and 2005. We discovered that most frequently the children experience dental avulsion in the age between 8 and 11 years old, the most affected teeth are the upper central incisors and the most frequent causes are sports and games which are very common in these ages, in various environments, like schools, sport fields and home. The majority of the children were transferred to the Dentistry Department either quite long after the avulsion incident and without the avulsed teeth, or with the avulsed teeth which were carried in an inappropriate transport medium, indicating that there is insufficient knowledge of adult people, especially the ones who are in daily contact with children, on how to provide first aid in cases of dental avulsion.
This study deals with the evaluation of endodontic treatment using calcium hydroxide materials in immature permanent teeth that have sustained traumas, especially after severe periodontal tissue ...injuries. - The aim of this work was: a. to analyze the factors that contribute to occurrence of post-traumatic complications, especially after avulsion injuries in immature permanent teeth , b. to investigate the effectiveness of endodontic therapy of these complications with the use of calcium hydroxide materials in immature permanent teeth, c. to evaluate various calcium hydroxide materials, d. to compare our results with other studies in literature concerning calcium hydroxide properties in cases that it is used as an intra-canal medicament. - The pre-clinical and clinical parts of this thesis are divided in 3 parts: 1. Evaluation of primary schools teachers` knowledge on providing first aid in cases of tooth avulsion injuries: immediate and proper first aid and fast transfer of children to dental practitioner are determining factors for prognosis of the injured tooth and for future occurrence of post-traumatic complications. 300 teachers were asked to fill questionnaires about avulsion of permanent teeth. 69 % of the respondents had never been informed about providing first aid in dental trauma situations, 34 %...
