Intrusive luxation is the most common trauma during early infancy which results in the displacement of the tooth into its alveolus. Depending on the severity of the intrusion, the American Academy of Pediatric Dentistry recommends either extraction or spontaneous re-eruption for the primary tooth. This case report provides a brief insight into surgical repositioning as an alternative treatment option for the management of intruded primary tooth in a 4-year-old girl.

Objective The aim of the present study is to compare and assess the risk of periodontitis due to the presence of four putative periodontopathic bacteria viz., Eikenella corrodens , Campylobacter rectus , Prevotella intermedia and Prevotella nigrescens . To fulfil the above objective, polymerase Chain reaction using the primers targeting 16S rRNA gene of the bacterial species was performed with the subgingival plaque collected from the permanent first molars of type 1 diabetic children and age matched healthy children. Results The prevalence of periodontal pathogens in diabetic and healthy children was 6% and 16% for E. corrodens , 18% and 36% for C. rectus , 2% and 2% for P. intermedia , 4% and 0%, for P. nigrescens respectively. Statistically, significant difference was not observed for the prevalence of all the four periodontal pathogens between type 1 diabetic and healthy children (P = 1.00). The results of the present study thus reveal a negative correlation of type I diabetes to periodontitis in association to Eikenella corrodens , Campylobacter rectus , Prevotella intermedia and Prevotella nigrescens .
