Selected AbstractsAvulsed permanent incisors: knowledge and attitudes of primary school teachers with regard to emergency managementINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 5 2001C. Blakytny Summary. Objectives. This study was designed to examine the knowledge and attitudes of primary school teachers with regard to the emergency management of avulsed permanent incisors. Design. Data were collected by self-administered questionnaire. Setting. The study was conducted in primary schools lying within a 2-mile radius of the University Dental Hospital, Cardiff. Sample and methods. A total of 388 teachers in 31 participating schools were asked to complete a questionnaire, which was subsequently collected by two of the authors (CS and AT). Results. Two hundred and seventy-four teachers returned completed questionnaires, a response rate of 70·6%. One hundred and eighty-one respondents (60·1%) had received no advice about the emergency management of dental avulsion. Of the 133 teachers (48·5%) who possessed a first aid certificate, 39 (29·3%) had been given relevant advice as part of this training. Less than one-third of respondents (85 (31%)) cited an optimum extra-oral time of 30 min or less, with only 43 (15·7%) considering that this should be 10 min or less. However, 125 (45·6%) knew milk to be the best transport medium. Two hundred and four teachers (74·5%) stated that they would not be prepared to replant an avulsed tooth themselves, 133 (80%) basing this decision on lack of expertise and training. Two hundred and sixty-two teachers (95·6%) expressed a desire for further information. Conclusions. The majority of respondents possessed, at best, rudimentary knowledge of the emergency management of dental avulsion. Teachers, and other individuals who supervise children in schools, should receive simple instruction in dental first aid. [source] Clinical evaluation of Procera AllCeram crowns in Japanese patients: results after 5 yearsJOURNAL OF ORAL REHABILITATION, Issue 11 2009Y. KOKUBO Summary, Procera AllCeram crowns were prospectively evaluated clinically in both anterior and posterior regions in Japanese. One-hundred and one crowns were fabricated for 57 patients at the Tsurumi University Dental Hospital from August 2001 to October 2002 and evaluated according to the California Dental Association (CDA) quality evaluation system at baseline and annually at all follow-up examinations for 5 years. The plaque index (PI) and gingival index (GI) were recorded, and chipping and fracture were checked at the same time as well. A total of 75 Procera AllCeram crowns were evaluated, and the cumulative survival rate was 90·2% over the 5-year clinical trial. Six crowns experienced fractures within the veneering porcelain and from aluminium oxide coping, all of which occurred on the premolar and molar regions, and they had to be removed. Small chipping was observed on three crowns. According to the CDA criteria, 98% of Procera AllCeram crowns were rated as satisfactory, and PI and GI were comparable to those of control teeth during the observation period. [source] Factors associated with the temporomandibular disorder, pain dysfunction syndrome (PDS): Manchester case,control studyORAL DISEASES, Issue 6 2001TV Macfarlane OBJECTIVES:,To determine the individual and combined effects of potential risk factors in relation to the temporomandibular disorder, Pain Dysfunction Syndrome (PDS). DESIGN:,Case,control study. MATERIAL AND METHODS:,Cases were new referrals to the temporomandibular disorder clinic of the University Dental Hospital of Manchester, diagnosed with PDS. Controls were randomly selected from 24 dental practices. Using a postal questionnaire information was collected on socio-demographic, local mechanical, psychological factors, co-morbidities and illness behaviour. The adjusted participation rate was similar in cases and controls (64%), and 131 cases and 196 controls finally participated in the study. RESULTS:,Compared with the controls, the cases were more likely to report that their teeth felt as though they did not fit together properly [odds ratio (OR) 8, 95% Confidence Interval (CI) 6,13] and report history of facial trauma (OR 3, 95% CI 2,6). Both diurnal and nocturnal grinding were significantly associated with PDS, and individuals who reported grinding their teeth both during the day and at night had a risk of 6; 95% CI 3,13 for PDS compared with those who did not. A history of orthodontic treatment, having any dentures, having missing teeth, use of chewing gum or biting the fingernails did not show any relationship with PDS. People who took medication for the bowels had a higher risk of PDS (OR 2, 95% CI 1,4). Participants with frequent headaches had a threefold increase in risk of having PDS (OR 3, 95% CI 2,5) while having pain in parts of the body other than the head was associated with an OR of 3 (95% CI 2,5). An increased propensity to have PDS was seen in those individuals with higher levels of psychological distress (OR 3; 95% CI 1,4 in the highest category, test for trend P < 0.001) and sleep disturbance (OR 5; 95% CI 2,94 in the highest category, test for trend P < 0.001). Aspects of illness behaviour, such as disease conviction (OR 4; 95% CI 2,9 in the highest category) and perception of illness (0.3; 95% CI 0.2,0.5) were associated with PDS. The result for the denial scale became statistically significant after adjustment for age and gender (2; 95% CI 1,3). CONCLUSIONS:,The current case,control study provides complementary epidemiological information on oro-facial pain (OFP) and supports a multifactorial aetiology of PDS, with factors from many domains, including local mechanical factors, psychological and co-morbidities. People with PDS were characterized by frequent headaches, history of facial trauma, teeth grinding, sleep problems, pain elsewhere in the body and high levels of psychological distress. From the results of current study and available evidence it seems inappropriate to consider PDS in isolation and future research should adopt a multidisciplinary approach to OFP. [source] Willingness to pay for implant therapy: a study of patient preferenceCLINICAL ORAL IMPLANTS RESEARCH, Issue 8 2010Katherine C. M. Leung Abstract Aims: This study determined the amount of willingness to pay (WTP) for implant treatment and identified the factors affecting WTP. Methods: Subjects attending a university dental hospital were recruited (n=59). They were presented with two hypothetical clinical scenarios: missing one anterior/posterior tooth. The clinical procedures, outcome and plausible complications of various replacement options (fixed and removable partial dentures, implants) and sequelae of no treatment were presented. They were then asked how much they were willing to pay for tooth replacement under the two situations using a bidding method, with a starting bid of Hong Kong (HK)$20,000 in HK$1000 increment/decrement if they were willing/unwilling to pay that amount (1 USD=7.8 HKD). The amount was recorded at which the subject chose the opposite option or it reached HK$0. Demographic data were also collected. WTP values were compared between anterior and posterior replacements, and among various demographic subgroups. Spearman's correlations and linear regression analysis were also conducted. Results: Ninety-four percent and 84% of the subjects chose implant treatment to replace missing anterior and posterior teeth, respectively. The mean WTP amounts for anterior/posterior tooth replacement were HK$11,000/HK$10,000 (P>0.05). Higher WTP amounts were obtained from females, subjects without missing teeth or restorative need, and had attained higher level of education (P<0.05). Gender (P<0.05), level of education (P=0.042), and the presence of missing teeth (P=0.001) were independent predictors of WTP. Conclusions: The estimated WTP value for a single tooth replacement using dental implants was HK$10,000. Gender, level of education and presence of missing teeth were independent predictors that influenced WTP. To cite this article: Leung KCM, McGrath CPJ.
