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 was to evaluate the presence of Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans) and Porphyromonas gingivalis (P. gingivalis) in subgingival plaque of healthy young children aged between 3 and 15 years using Polymerase Chain Reaction (PCR) and to compare their presence in children in their primary, mixed and permanent dentitions. Method: Subgingival plaque samples were collected from 120 healthy children and were grouped as Group I-Deciduous dentition, Group II- Mixed dentition and Group III- Permanent dentition, and were subjected to PCR assay. Results: Binomial test and Proportions test were used for statistical analysis. A. actinomycetemcomitans and P. gingivalis were detected in 5% and 35%, 12.5% and 20%, and 0% and 27.5% samples in group I, II and III respectively Conclusion: Both the microorganisms were present in group I and II. In group III only P. gingivalis was present. The results from this study do not necessarily pertain to differences in dentition but possibly to inter-individual differences.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
