In this study, the application of additional flowable composite lining with various thicknesses presented different influences in marginal quality of class II box only composite restorations. A new technique applying an ultrathin flowable composite lining with cocuring technique improved the marginal sealing with decreased microleakage. Restorations with thin lining presented reduced marginal integrity after thermocycling.

Dentigerous cysts are the most common developmental odontogenic cysts of the jaw, arising from impacted, embedded or unerupted permanent teeth. They apparently develop by accumulation of fluid between the reduced enamel epithelium and the tooth crown of an unerupted tooth. There is usually no pain or discomfort associated with the cyst unless there is an acute inflammatory exacerbation. Careful evaluation, coupled with meticulous clinical and radiological investigations could help clinicians to arrive at the correct diagnosis as well as address the implicated etiologies, before instituting the most appropriate therapy. Here, we report a case of a dentigerous cyst in the mixed dentition of a 10-year-old female patient and outline its comprehensive management for the benefit of pediatric and general dentists involved in the care of such patients.

Supernumerary teeth are common in general population and occur frequently in patients with familial trait. However, it is rare to find supernumeraries in individuals with no associated disease or syndrome. Supernumerary teeth are found in any region of maxilla and mandible, with a predisposition for anterior maxilla. A case of endodontically involved supernumerary lateral incisor is described.
