ABSTRACT: The purpose of this retrospective study was to identify the types, causes, and other factors associated with traumatic dental injuries (TDIs) in the permanent teeth of children in Mosul, Iraq. Data were collected from the dental records of 6- to 12-year-old children with TDIs who attended the Pediatric Dental Clinic at the Mosul University School of Dentistry between October 2006 and October 2010. The gathered data included: demographic information, when and where the injury occurred, type of dental injury, cause of injury, and the time elapsed between the TDI and dental care. Data were evaluated using the chi-square test. A total of 294 children with TDIs were examined and treated. The highest frequency of TDIs was among 12-year-old children (29%), with more males being affected (P<.001). The most common type of injury was enamel-dentin fracture (56%). The most frequent cause of TDIs was falls (53%). The majority of the injuries happened outdoors (55%), and 37% of the cases occurred in the Fall. Only 5% of patients sought dental care within 24 hours of the injury. This 4-year retrospective study showed that the majority of children with TDIs sought dental treatment after one month of the injury. Educating parents and teachers about the benefits of trauma prevention and immediate treatment of injuries is a must.Journal of dentistry for children (Chicago, Ill.) 01/2013; 80(1):3-8.
Article: The effect of frequency of calcium hydroxide dressing change and various pre- and inter-operative factors on the endodontic treatment of traumatized immature permanent incisors.[show abstract] [hide abstract]
ABSTRACT: The objectives of this clinical study were as follows: (i) to determine the effect of frequency of calcium hydroxide [Ca(OH)(2)] dressing change on the apical barrier formation in immature permanent incisors with necrotic pulps and (ii) to investigate the effect of various clinical factors before and during treatment that may be associated with the frequency of Ca(OH)(2) dressing changes. The study involved 21 healthy subjects, 8-12 years old. Twenty-three immature traumatized permanent maxillary central incisors were treated using Ca(OH)(2) powder mixed with barium sulfate and distilled water. The progress of barrier formation was reviewed after 6 months of first placement of Ca(OH)(2) and then every 3 months until the detection of an apical barrier. Clinical and radiographic evaluations were performed before and after treatment. Data were evaluated using a chi-square test. Apical barrier formation was successful for all 23 teeth. Seventeen teeth (74%) needed only a single application of Ca(OH)(2), while six teeth (26%) required more than one application. The average time of apical barrier formation was 30 weeks, and the mean number of Ca(OH)(2) dressing changes was 1.3. A significant positive association was found between teeth that presented with displacement and the number of Ca(OH)(2) dressing changes (P = 0.004). An initial 6-month application of Ca(OH)(2) dressing followed by 3-month replacements (usually in teeth presenting with displacement and/or sinus tracts) may be successfully used in apexification treatment. This would assist in reducing the number of Ca(OH)(2) dressing changes, number of appointments, cost of treatment and radiation exposure.Dental Traumatology 11/2011; 28(4):296-301. · 1.20 Impact Factor
