Purpose. To compare errors in digital panoramic radiographs of permanent and mixed dentitions.Methods. 143 and 146 digital radiographs of mixed and permanent dentitions were examined.Results. Significantly fewer errors presented in the mixed dentition. Positioning too forward significantly prevalent in the mixed dentition; slumped position and nonpositioning of chin properly were significantly prevailed in the permanent dentition. Blurred or shortened upper incisors were significantly more prevalent in the mixed dentition. Diagnostic ability could be improved by manipulating the brightness or contrast in nearly 45% of all radiographs. In the mixed dentition, tilting the chin down and a slumped position made the lower incisors significantly nondiagnostic. In the permanent dentition, tilting the chin down made the lower incisors to be significantly nondiagnostic.Conclusions. More errors were prevalent in panoramic radiographs of permanent dentitions. Properly positioning the patient is the most important factor in preventing a cascade of errors.

Aim: To evaluate parents' acceptance of management techniques in Israeli pediatric dental clinics. Study Design: Ninety parents who accompanied their children to three pediatric dental clinics provided information on selected parameters including their attitudes about management techniques. Results: 68.9% of the parents preferred to stay in the treatment room. The most accepted technique was positive reinforcement (81.1%) followed by tell-show-do (TSD) (76.7%, with younger parents more accepting than older, p = 0.049). The least accepted techniques were restraint (1.1%) and voice control (7.8%, especially by parents with the highest dental anxiety, p = 0.002). Sedation was unacceptable by 15.6% of the parents: those with the lowest dental anxiety agreed to sedation significantly more than those with greater dental anxiety (p = 0.031). Conclusions: Parents preferred more positive approaches and management techniques that involve demonstrations geared for the child's level of understanding. Restraint and voice control were more strongly rejected than sedation.
