Incidence of traumatic dental injury in Valencia, Spain.

BACKGROUND: While traumatic dental injuries (TDI) are an increasingly frequent occurrence in everyday dental practice, little research on TDIs has been published in Spain. The aim of this study was to determine the incidence of TDIs in a population in Valencia (Spain) and investigate influential variables. In addition, a protocol for TDI data collection is proposed. MATERIAL AND METHODS: This retrospective study compiled data from patients attending a private dental clinic between January 2003 and December 2014. The data were collected using a specially-elaborated protocol entitled "Emergency care of acute dental trauma". Patients responded to each item, and data was added from case radiographs and photographs. Data were entered in a Microsoft Office Excel spreadsheet and submitted for analysis by SPSS 15.0 software (Chicago, IL) applying 2-way analysis of variance (ANOVA) (p<0.01). RESULTS: 481 TDIs in 251 patients were examined at a private dental practice in Valencia. The population comprised 62.5% men and 37.5% women, aged 1 to 78 years. The highest frequency of tooth injuries occurred in children aged 9 years or younger. The most frequent injury was non-complicated crown fracture (43.2%). Upper central incisors were the most commonly affected teeth. The most frequent place where TDI was produced was in the street (28.7%), tripping over an immobile object being the most common cause (29%). CONCLUSIONS: Thanks to the protocol elaborated for the purposes of this work, it was possible to compile a large quantity of data on TDI, facilitating future prevention and comparison with other regions. The results obtained concur with those published in the literature.

Composite resin inlays: a study of marginal adaptation.

Ten mesio-occlusodistal composite resin inlays were fabricated by the indirect method and cemented in extracted posterior teeth. The restorations were subjected to thermocycling and subsequently placed in a 50% silver nitrate solution. Specimens were prepared and inspected under a stereoscopic microscope and a scanning electron microscope. The results showed a total absence of microleakage at the margins terminating in enamel and a slight degree of microleakage in only two margins terminating in cementum. This corresponded with the general absence of defects and gaps that was observed in the scanning electron microscope. The exception was in the two specimens that exhibited dye penetration; these were found to have material in the marginal areas.

[Diagnosis of compound odontoma. Apropos of 2 cases]. / Diagnóstico del odontoma compuesto. A propósito de dos casos clínicos.

We have a bibliografical study of the composite odontomas from the diagnostical point of view. We will present two clinical cases. Once the medical revision is done, and the tumor is localized, we analyze lesions associated with the tumor and compare the diagnostic from the clinical point of view as well as the radiografical point of view.
