Comparative Evaluation of Microleakage in Hall's with SDF, Hall's, and Conventional Technique Using Different Luting Cements.

The most common pathological condition, dental caries when remain untreated which shows pulpal involvement and may lead to invasive treatment, such as crown placement followed by pulp therapy. Larger carious lesions on primary molars stainless steel crowns (SSCs) placement by means of conventional tooth preparation. The modern approach to managing carious lesions concentrates on using less invasive treatment techniques, with the focus being on biofilm change. One among such alternative method of managing the primary molars is the Hall's technique. Another most important factor for the survival of a crown is its sealing ability, in which luting cements, such as adhesive cements, have a crucial role as they help in providing a suitable marginal seal and thereby cause a reduction in the microleakage. Silver diamine fluoride (SDF) has proven anticariogenic activity in arresting carious lesions. Hence the aim was to evaluate and compare the microleakage of SSCs placed by Hall's technique, Hall's technique with SDF, and the conventional crown technique using different luting cements. A total of 60 primary first and second molars with occlusoproximal caries, which were initial and moderate in nature. The blocks were randomly divided into three groups, in which precontoured SSCs were applied by using either the Hall's technique or the conventional technique. After subjecting tothermocycling, the samples were examined under stereomicroscopic for microleakage evaluation. A few samples were randomly selected from each subgroup, and a scanning electron microscopic (SEM) examination was done. Highest values of microleakage were noted with Hall's technique resin-modified glass ionomer cements (RMGIC) luting cement group. It can be concluded from the present study that the conventional technique was found to be superior over the Hall's technique with SDF and then by the Hall's group alone. SDF application beneath the Hall's crown appears to be promising approach for the reduction of microleakage. How to cite this article: Thakur NS, Tyagi P, Tiwari S,
