ABSTRACT
Aim: The present research was conducted to assess the microleakage of stainless steel crowns along with pedo jacket crowns following cementation with different luting cements. Materials and Methods: A total of 60 deciduous teeth subjected to extraction were employed in this in vitro research. These 60 specimens were randomly divided into two groups: Group I: Stainless steel crowns and Group II: Pedo Jacket crowns. Both crowns were subjected to cementation using self-cure resin-modified glass ionomer (RMGI) cement as well as by means of self-adhesive universal resin cement (RelyX luting cement). The specimens were subjected to storage in distilled water at 37°C for 24 h and were subjected to 500 thermal cycles between 5°C and 55°C using a dwell span of 30 s. Individual surfaces were assessed for the amount of dye infiltration at the boundaries by the side of the tooth-cement border beneath a stereomicroscope under 50× magnifying power. At the mesial and distal surfaces, the amount of microleakage was measured in micrometers (µm), and the mean value was computed for each sample. Results: Stainless steel crowns subject to cementation with RelyX luting cement exhibited the lowest microleakage (0.88 ± 0.78) versus self-cure RMGI cement (0.94 ± 0.78). There was no statistically significant difference found between the groups. Pedo Jacket crowns subject to cementation with RelyX luting cement exhibited the lowest microleakage (0.96. ± 0.32) while self-cure RMGI cement (1.83 ± 0.16) depicted the maximum microleakage. There was an extremely statistically noteworthy dissimilarity noted among the groups. Conclusion: The current research concluded that Pedo Jacket crowns subjected to cementation with RelyX luting cement can be regarded as an esthetically pleasing restorative alternative for numerous young patients. Applying RelyX luting cement to Pedo Jacket crowns provides a strong bolstering by composite materials that ensures the success of the therapy provided.
ABSTRACT
AIM: The aim of this study was to evaluate the effect of the Aculief acupressure device on the reduction of pain during local anesthesia (LA) in children and to compare it with the cryotherapy technique. METHODOLOGY: 20 children of age group between 6 and 9 years, requiring pulpectomy or extraction bilaterally were chosen for the study. After ethical clearance and parental consent, children who were not experienced to prior local anesthesia were chosen for the study. A split-mouth study design was done to avoid bias, and children were divided into two groups. During the first visit cryotherapy application was done on any one side followed by the LA, and during the second visit Aculief acupressure application was done, which was followed by the LA. The objective and subjective evaluation of pain during the LA was carried out and analyzed. RESULTS: The objective perception of pain was evaluated using the Sound-Eye-Motor Scale by an observer who was blinded, and the subjective perception of pain by the Wong-Baker Faces Pain Rating Scale was evaluated by the child patient. The statistical analysis and comparison of values were done using the Wilcoxon signed-rank test. The pain during administration of LA was eliminated after the application of the Aculief acupressure device, and the results were superior to the cryotherapy technique. CONCLUSION: The Aculief acupressure device can be effectively used to eliminate pain perception while administering LA in children. It is a simple, safe, noninvasive, and effective device and is easy to perform.
