Context: Traumatic dental injury is one of the detrimental injuries faced by paediatric population. It has short or long lasting after effect on developing dentition and surrounding perioral structure. The prevalence and severity of traumatic dental injuries among in vitro fertilization (IVF) children of West Bengal is not documented till date.
Aims: The aim of this study is to evaluate the prevalence of traumatic dental injury among IVF children of West Bengal evaluated through Ellis and Davey’s (1960) criteria.
Settings and Design: In a cross-sectional case control study, a total of 239 teeth of 158 IVF children (aged 6 month to 14 years) seen from 2009 to 2011 were surveyed, comprising of both traumatized primary and permanent teeth. A total of 947 teeth of 763 spontaneously conceived children (aged 6 month to 14 years) comprising of both traumatized primary and permanent teeth were kept as control fulfilling the inclusion and exclusion criteria.
Methods and Material: The information of the samples was collected using a predesigned data sheet by a single examiner using WHO criteria and Ellis and Davey’s (1960) classification. Case group consisted of term, singleton babies who were the outcome of IVF in the studied area in 2009- 2011. The control group consisted of spontaneously conceived children of the same area.
Statistical analysis used: Statistical analysis was carried out using Z-test.
Results: No statistically significant difference found in studied (IVF children) and control group (spontaneously conceived children) except in 8 category like fall fight, TDI due to other causes group, in age wise division such as group I, II and III, as well as in class IX type of TDI and in permanent maxillary lateral incisor category, where the results are statistically significant at P < 0.05.
Conclusions: IVF children are considered nearly same as spontaneously conceived children when studied according to TDI except in 8 categories. So they may be treated in the same manner as like spontaneously conceived children with a little bit of more precaution because they are more precious to their parent.
