Abstract
Aims: To determine the prevalence of traumatic dental injuries in the anteriorsegment and associated risk factors for 9-12 years old school children in Wad-Madani locality, Al-Gazira state, Sudan.Material and method: A cross-sectional school base study for six hundred and eighty 9-12 year- old school children (boys and girls) selected randomly from 25 basic schools. Andresen’s criteria were used to record traumatic dental injuries by visual examination and no radiographs were taken. Associated risk factors were assessed (age, gender, over jet and lip Competency). Chi-square test was used to test association between the different variables. P -value < 0.05 was considered statistically significant.Results: The prevalence of traumatic dental injuries was 9.1%. Boys experienced more injuries than girls 1:2.2. Enamel fracture (63%) was most common types followed by enamel and dentine fracture (27%). The maxillary central incisor was the most common affected tooth (79.7%). Collisions were the main cause of trauma and home the most common place. Most of the traumatized teeth were not treated. The high percentage of traumatized teeth associated with increased over jet (P = 0.000) and inadequate upper lip coverage (P = 0.000). Conclusion: The present study revealed a relatively low prevalence of dental trauma, but still high when compared with literature. Significant association between dental trauma and associated factors (age, gender, over jet and lip Competency) were found. Educational programs should be initiated for the community regarding causes, prevention and treatment of traumatic dental injuries is mandatory to elaborate preventive strategies and efficient treatment plans.
Highlights
Traumatic dental injuries are worldwide spread and one of the main reasons for dental emergencies among children and adolescent[1,2]
In the current study the maxillary central incisors were the most common teeth affected by dental trauma that was inagreement with the studies reported by many authors[22,23,24]
The present study is a cross sectional, school-based study, that investigated the prevalence, cause, common type, risk factors, and treatment received of traumatic dental injuries for sample of Sudanese school children in Wad-Madani locality
Summary
Traumatic dental injuries are worldwide spread and one of the main reasons for dental emergencies among children and adolescent[1,2]. Worldwide epidemiological studies of dental trauma have been reported a wide range of prevalence 5.1% to 58.6% regardlessto the type of study[4,5]. He majority of traumatic dental injuries affected the anterior teeth, especially the maxillary centrals. The prevalence of dental trauma had been early studied among 6–12 years old Sudanese school children by Baghdadi et al and 5.1% was recorded[4].
