Aim: Low-level laser therapy (LLLT) has been increasingly used over the past few decades in both medicine and dentistry. It has been suggested that LLLT may be helpful in pulpal wound healing following pulp exposure. The purpose of this study was to evaluate the histological changes in dental pulp tissue after a pulpotomy procedure using a low-level diode laser in comparison with the gold standard formocresol. Materials and methods: In this experimental split-mouth study, 20 teeth were randomly selected from five dogs. The animals were anesthetized and pulpotomized using a low-level diode laser (660 nm, 36 mW) and formocresol respectively. One week later, the pulpotomized teeth were extracted and subjected to histological evaluation. Histological changes seen in the pulp tissues of all the interventional groups were subjected to statistical analysis using Mann-Whitney U test for pairwise comparison; p < 0.05 was considered as statistically significant and p > 0.05 nonsignificant. Results: On histologic evaluation, least amount of inflammation and maximal healing was evident in the LLLT group. On the contrary, the formocresol group showed severe inflammation. Conclusion: Low-level laser therapy promises to be a safe, minimally invasive, yet maximally effective modality for pulpotomy.
The present study aims to clinically evaluate the performance of a glass hybrid glass ionomer cement (GIC), Equia forte (GC India) and a bulk fill composite, Tetric N Ceram (Ivoclar Vivadent) in restoration of class II carious lesions in primary molars for a period of 12 months. A total of 39 patients of 5-9 years with occlusoproximal carious lesion on primary maxillary or mandibular molars were selected and randomly allotted into two groups i.e Group A (Equia Forte) and Group B (Tetric N Ceram). A total of 78 restorations (39 teeth for each group) was placed using Equia Forte and Tetric N Ceram using a split mouth design and were evaluated for a period of 12 months at regular time intervals using FDI criteria by two blinded examiners for esthetic, functional and biological properties. The data were analyzed using one way ANOVA for intragroup comparison and student t test for intergroup comparison. There was no statistically significant difference seen at baseline, 3, 6, 9 and 12 months for esthetic, functional and biological properties within the group. On inter group comparison, there was no statistically significant result observed except for functional property at 6 months with a p value of 0.02. The current study suggests that both Equia Forte and Tetric N Ceram can be a choice of restorative material in class II carious lesions in primary molars.
Introduction: Pedodontists have always looked for newer techniques, safer materials, and ergonomic technologies to treat pulpal infections so as to help children heal faster. Low-level laser is one such innovation that needs to be assessed for its efficacy as a potential pulpotomy medicament.Aim: To evaluate the histological changes in the dental pulp of dog's primary premolars after pulpotomy using low-level diode laser therapy (LLLT) in comparison with mineral trioxide aggregate (MTA), and Pulpotec.
Design:In this experimental study, 30 teeth were randomly selected from five dogs. The animals were anesthetized and pulpotomized using LLLT, MTA, and Pulpotec respectively. One week later, the pulpotomized teeth were extracted and subjected to histological evaluation for inflammation. Histological changes seen in the pulp tissues of all the groups were subjected to statistical analysis using Kruskal-Wallis test for groupwise analysis (p-value of < 0.001) and for pairwise Mann-Whitney U test (p-value of < 0.05).Results: On histologic observations, least inflammation was seen in low-level laser group followed by Pulpotec. Severe inflammatory cell infiltrates were seen in MTA.
Conclusion:Low-level laser therapy appears to be a safe, minimally invasive, yet an effective modality for pulpotomy followed by Pulpotec.
Pierre robin sequence is characterized by the triad of mandibular micrognathia, ‘U’ shaped cleft palate, and glossoptosis. Infants with this condition usually present with airway obstruction and feeding difficulties. This in turn leads to low weight and nutritional deficiencies which might delay the surgical intervention for the same. This case report describes a one-month-old infant with Pierre Robin sequence presenting with feeding difficulty and nasal regurgitation due to a ‘U’ shaped cleft palate. Elastomeric impression followed by fabrication of feeding plate with auto-polymerizing resin was done. Additional ‘S-shaped’ retentive arms were provided from the intra-oral to extra-oral side wire to provide additional retention and to prevent injury to both the child and parent while feeding. Early insertion of a feeding plate helps to prevent nasal regurgitation, to gain weight, and to guide the growth of the mandible in a child with Pierre Robin Sequence.
