fracture pattern of maxillary incisors in children and adolescence: a new morphological classification

Traumatic dental injuries are frequent in the maxillary anterior teeth for variety of reasons like falling down in street or school, collision and sports. Many local occlusal factors such as increased overjet and general factors such as increased activity may predispose and modify these traumatic injuries. Many studies have attempted to classify the types of traumatic dental injuries based on the extent of the tooth structure involvement and the severity of the trauma. Central incisors act as one unified segment during traumatic injuries and do fracture always in certain repeated morphological patterns every time they are subjected to impact trauma. One hundred and forty [140] children were examined at their first presentation in the restorative-pe-diatric dentistry department and data was collected from new dental traumatic injuries in order to classify these morphological patterns of trauma and see which of them are happening more than others and their relationship with overjet. Data revealed that there were repeated fracture patterns which can be divided into seven morphological categories and increased overjet was more predisposeing factor

relationship between dental anxiety and reported dental treatment experience in children aged 11 to 14 years

The aim of the study was to determine the influence of reported dental experience on dental anxiety in children aged 11-14 years in Liverpool, United Kingdom. A total 366 children completed a two-part questionnaire. The first part invited the children to record which dental procedures they had experienced. These procedures were the same as those included in the Modified Child Dental Anxiety Scale, which formed the second part of the questionnaire. The scale consisted of eight questions, which invited the children to rate their anxiety about a variety of dental procedures, including going to the dentist in general, a dental examination, a scale and polish, local anaesthesia, dental restoration, dental extraction, dental treatment under general anaesthesia and dental treatment under inhalation sedation. The Modified Child Dental Anxiety Scale allowed the children to report on a five point Likert scale about how relaxed or worried they were for each of these scenarios. Cross-tabulation and t-tests were used to determine the relationship between dental anxiety and reported dental experience. The significance level for the study was set at p<0.05. Females were found to have significantly higher [p<0.05] mean anxiety score [21.87] than males [18.90]. Children were significantly less anxious about specific items of dental treatment if they had experienced that particular form of treatment. In the study group of 366 children, 232 [63.4%] reported that they had experienced a dental filling had a mean anxiety score of 2.23, 105 [28.7%] children reported that they had not experienced a dental filling had a mean value for the dental filling item of 2.70. Females were found to be statistically more dentally anxious than males. Children who reported that they had experienced dental treatment and visited the dentist more frequently were significantly less anxious than those who reported infrequent visits
