Students' attitudes and knowledge on pain and pain management in paediatric dentistry-An observational study.

INTRODUCTION: The dental and dental hygienist educational programs prepare students with knowledge on children's prophylactic pain treatment and pain management. Observing the students' understanding could help educational efforts to be more student oriented. The aim was to evaluate dental and dental hygienist students' knowledge and attitudes on pain prevention and pain management in children and adolescents, applying a multidimensional questionnaire previously used on general dental practitioners. MATERIALS AND METHODS: Three hundred and four dental and dental hygienist students at Swedish universities were eligible for the survey. Written and oral information was given about the study's aim, methods, anonymity and voluntary participation. The multidimensional questionnaire included 47 closed questions. RESULTS: The total responding rate was 65.4%; dental students 61.1% and dental hygienist students 92.8%. The total mean of knowledge and attitudes, beneficial for the treating of patient pain, varied between 57.1% and 83.3%. The biggest knowledge gap was identified regarding the items: Children under 2 years of age experience less pain than children over 2 years undergoing similar treatment(34.3%), The dentist is better suited than the parent to judge if a child is in pain (29.4%), and usually the child's pain experience diminishes when the parents are present (24.2%). CONCLUSION: Dental and dental hygienist students reported vastly spread knowledge and attitudes regarding pain prophylactic and pain management in children and adolescents, as measured by a multidimensional questionnaire previously used on GDPs. Knowledge on students' understanding of the young patient's pain could help educational efforts to be more student oriented. The questionnaire must be further modified and more extensively tested to meet each participating students' program level.

General dental practitioners' knowledge and attitudes on children's pain and pain management-A questionnaire survey.

The aim was to study general dental practitioners' knowledge and attitudes on pain and pain management in children and adolescents, using a multidimensional questionnaire. There is little information on dentists' views on pain in children. The research question was how attitudes and knowledge may correlate to the dentists' age, sex, years of professional experience, the proportion of working time devoted to treating children and adolescents, as well as being a parent. At the time of the study, 387 general dentists working for the Public Dental Service participated in a web-based, multidimensional validated questionnaire holding the categories (A) views on the care of children in pain, (B) physiology, (C) pain alleviation, (D) medication, (E) sociology/psychology, (F) Pain assessment instruments and methods, (G) non-medication methods of pain alleviation, and (H) documentation of pain management. The age categories were given as; below 25, 25-35, 36-45, 46-55 years, and older than 55 years of age. 71% of the responders were female. The dentists' age cohort, as well as the years of professional experience, tended to make a difference as to the pain interventions in children and adolescents (P < 0.03). The female dentists, in comparison to the male dentists, conveyed different pain treatment strategies (P < 0.03). The proportion of working time devoted to treating children and adolescents, as well as being a parent, did not show significant differences regarding pain strategies. Associations were observed between the age of the dentists studied, the number of years as professionals and the knowledge and attitudes that benefit children's pain treatment. Being a parent was not significant. In this studied group, female dentists displayed significantly more care regarding pain management, than did their male colleagues. Furthermore, the study highlighted the need for a short questionnaire, user-friendly yet with retained multidimensionality.

An explorative analysis of the recruitment of patients to a randomised controlled trial in adolescents with dental anxiety.

Randomised controlled trials (RCTs) are considered to provide the most reliable evidence on the efficacy of interventions. The aim of this study was to describe the recruitment process of an RCT study set up to evaluate a Cognitive Behavioural Therapy (CBT) intervention programme for adolescent patients with dental anxiety (DA). The participants were recruited from a consecutive sample of adolescent patients (12-19 yrs old) referred for DA to a specialised pediatric dentistry clinic. Age, gender, and reason for referral were recorded for the possible eligible patients as part of the drop-out analysis of the recruitment process. Participants were then randomized to the intervention (CBT integrated with dental treatment) or control (adapted dental treatment) condition. In the recruitment process, 138 possible eligible patients met inclusion criteria, of these 55 were enrolled, 44 declined participation and 39 patients were excluded.The patients enrolled in the RCT did not differ from the non-participants with regard to age, gender or cause of referral. As a result of difficulties in the recruitment process, the study period was extended. The considerable proportion of non-participants as evident from the recruitment process may pose a threat to the external validity of the clinical trial. From a clinical perspective, the reasons for the lack of motivation to participate in behavioural interventions and the failure to appear warrant further investigation.

Common experiences of pain in children and adolescents--an exploratory factor analysis of a questionnaire.

The aim of the study was to reduce everyday and dental treatment pain items included in the extended Children's Pain Inventory (CPI), used in a prior study on Swedish children and adolescents. Another aim was to, by means of exploratory factor analysis (EFA), expose hitherto undiscovered dimensions of the CPI pain variables and thus to improve the psychometric properties of CPI. As some pain items are relevant merely to some individuals, a new and more useful questionnaire construction would enhance the internal validity of the instrument in observational surveys. EFA was applied on the extended CPI instrument. 368 children, 8-19 years old, had answered a questionnaire comprising 10 dental and 28 everyday pain variables. These pain items were analysed using a series of sequentially implemented EFA. Interpretations and decisions on the final number of the extracted factors was based on accepted principles; Kaiser's Eigenvalue >1 criterion, inspection of the scree plot and the interpretability of the items loading. The factors were orthogonally rotated using the Varimax method to maximize the amount of variance. Of all tested EFA models in the analysis, a two, three, four, and five factor model surfaced. The interpretability of the factors and their items loading were stepwise examined; the items were modulated and the factors re-evaluated. A four factor pain model emerged as the most interpretable, explaining 79% of the total variance depicting Eigenvalues > 1.014. The factors were named indicating the profile of the content: Factor I cutting trauma to skin/mucosal pain, Factor II head/neck pain, Factor III tenderness/blunt trauma pain, Factor IV oral/dental treatment pain.

Everyday- and dental-pain experiences in healthy Swedish 8-19 year olds: an epidemiological study.

BACKGROUND: Very little is known about children's everyday pains and dental treatment pains. A child's gender, age, and level of dental anxiety are factors that could interplay with the perception of pain and are thus worth studying. AIM: The objectives of this study were to investigate the frequency and reported intensity levels of children's everyday- and dental-pain experiences, and to study the reported pains in relation to gender, age, and dental anxiety. DESIGN: Three hundred and sixty-eight consecutive patients (8-19 years, mean age 13.5 years) from three different Public Dental Service were recruited. Pain ratings were obtained using McGrath's Children's Pain Inventory list and some additional items. Dental anxiety was estimated by the Dental Anxiety Scale. RESULTS: Most frequently experienced everyday pains were headache and tummy/stomach ache. Among dental treatment events, dental injection was reported to be most often ranked as painful, and more frequently by girls. Both dental and everyday pains were rated higher grouping children with high dental anxiety. CONCLUSIONS: The frequency of pain experiences are the same in Swedish children as in other populations. There is a relation between dental anxiety and the perception of pain.

The effect of growth hormone therapy on mandibular and cranial base development in children treated with total body irradiation.

The aim of the present investigation was to study craniomandibular development during growth hormone (GH) therapy in nine girls and one boy, aged between 7.3 and 16 years, who exhibited pronounced growth reduction after total body irradiation (TBI) and bone marrow transplantation (BMT). Age- and sex-matched healthy children with normal dentofacial development constituted the control material. The investigation data were based on measurements made on lateral skull radiographs taken at the start and, on average, 6 months after cessation of GH treatment. The control group comprised similar longitudinal cephalographic records. The results showed that GH therapy in patients who exhibited growth retardation after TBI and BMT had only a minor effect on cranial base dimensions, probably due to the fact that the development of this area is completed at a relatively early age. The effect of GH treatment on mandibular growth was very obvious. The dimensional increase of the mandibular variables in the patients was equivalent to, or in some cases even exceeded, that of the controls. In relation to basion, the mandibular condyles were displaced in a backward/upward direction in the patient group. Displacement in the opposite direction was recorded in the controls. It seems likely that the development seen in the patients is a reflection of a normalization of the condyle-fossa relationship made possible by enhanced condylar growth. This change should be advantageous for the function of the craniomandibular complex.
