The assessment of side effects of substances encountered in odontology by patients and the dental team must include the direct and indirect effects of irradiation emitted from polymerisation devices. The eyes of the lamp operators are at risk from acute and cumulative effects, mainly due to back-reflection of the blue light. Furthermore, phototoxic and photoallergic reactions originating from absorbed radiation in endogenous or exogenous substances accumulated in the operators' eyes and skin (hands) as well as the patients' oral mucosa must also be taken into consideration. Preventive measures include reading the manufacturers' operating instructions for curing devices and using radiation-filtering protection goggles.
A study was made of differences between children who had a history of refusing dental treatment in the community and control children, as rated by their parents. History of treatment refusal was found to be associated with a general fear of 'medical' people, intolerance for any pain or discomfort and greater difficulty in approaching novelty or adapting to change. These children were also rated by their parents as being generally more negative in their mood and having greater difficulty in playing with unfamiliar children. The implications of these findings are discussed.

PURPOSE: Accurate reporting of medical history information is essential to provide safe and successful dental treatment to children. The purpose of this study was to evaluate the accuracy of health histories reported by parents/guardians of pediatric patients presenting for dental treatment by comparing them to the histories provided in the child's medical chart. METHODS: Data collection from the dental record was performed using the medical history questionnaire from the child's first visit as the data source. Data collected focused on knowledge of the child's medical conditions, current medications, allergies, immunization status, and need for prophylactic antibiotics. Corresponding data were collected from the child's medical chart. Statistical analysis included kappa analysis and calculation of sensitivity, specificity, and failure-to-report rates. RESULTS: The study group consisted of 226 children (99 girls, 127 boys), with a mean age of 10.35 years. The patients were divided into 2 groups based on their medical status (healthy vs medically compromised). For the medically compromised children, parents had high sensitivity reporting rates (>75% sensitivity) for only 2 out of the 9 medical categories. For both groups, <50% of the medicine, allergy, and need for prophylaxis categories had sensitivity rates above 75%. Failure-to-report rates of 40% to 60% were common, with some as high as 80%. Weighted failure-to-report rates were consistently higher for medically compromised children compared to healthy children. CONCLUSIONS: Parents/guardians of children presenting for dental treatment are not always able to accurately report vital medical history information. Therefore, pediatric dentists need to more closely examine the dental health questionnaire and make every attempt to obtain accurate information to provide appropriate care for each patient.
This article, the fourth in a series, examines nonradiographic procedures and devices such as standard clinical and visual examination, apex locators, vitality testers and colour shade guides in light of the tools described in the first 2 articles in the series. A variety of nonradiographic indices and scales are used in detecting periodontal disease and monitoring and assessing its treatment. The reliability of these diagnostic procedures directly affects treatment success, decisions to initiate more aggressive clinical interventions, and the ability to make an informed prognosis about the course of the disease. However, in many instances, the dependability of the measurements remains to be established.
