Email this article In vivo assessment of clinical, radiographic and laser fluorescence examinations for the detection of secondary caries in Class I restorations
Abstract
Introduction: Contemporary conservative dentistry is mainly based on work using composite materials. This is connected not only with the possibility of their comprehensive applications, but also the aesthetic effects that can be achieved through a wide variety of materials. In cases where it is not possible to make a composite restoration properly, replacing it with an alternative material which will determine the more stable reconstruction of the tooth tissues should be considered. Improper composite restoration in a relatively short period of time can lead to marginal leakage, which contributes to the accumulation of dental plaque and the development of secondary caries.
The aim of the study was to assess the effectiveness of clinical, radiographic, and laser fluorescence examinations for the detection of secondary caries under Class I amalgam fillings and composite restorations.
Materials and methods: The study involved 94 patients, aged 17–67 years. We examined 200 restorations with marginal ditching, staining, or discoloration of the adjacent tooth tissues. Teeth with visible secondary caries were not included. Clinical, laser fluorescence and radiographic examinations were performed.
Results: Secondary caries was found in 137 of the 200 examined teeth. The laser fluorescence and radiographic examination methods showed low sensitivity for detecting secondary caries (0.31 and 0.39 respectively). Both methods showed higher specificity (0.86 and 0.98 respectively) and accuracy (0.49 and 0.58 respectively).
Conclusions: Clinical examination is the most effective method of diagnosing secondary caries in Class I restorations. Laser fluorescence and radiographic examinations should only be performed in addition to clinical examination.
