Introduction: With the society becoming more conscious on aesthetics and parents being more influential in choosing the crown for children, evaluating the parental satisfaction becomes a crucial element to be considered. Aim: The present study aims at evaluating the parental satisfaction and child’s acceptance of SSCs and Figaro crowns in primary molars. Materials and method: 50 children who received SSCs and Figaro crowns in the primary molars were identified for participation in the study. The children were clinically examined and the questionnaire for parent satisfaction was administered. Data was collected and subjected to statistical analysis. Results: The parental satisfaction with the colour of Figaro crowns was superior and was statistically significant (p=0.01). None of the parents were dissatisfied with the shape of the crown in both the crowns. All the parents in Figaro crown group were either satisfied or very satisfied with the size of the crown. With reference to the children’s overall rating score, 100% of the children were satisfied with Figaro crowns whereas only 36% of the children were satisfied with SSCs (p=0.01). Conclusion: Figaro crowns has a significant acceptance from both the parents and the children.

The esthetic lag in the full coverage restoration of preformed stainless steel crowns led to the development and use of open-face techniques, pre veneered crowns, and zirconia crowns. Fibreglass crowns (Figaro Crowns, Inc.; USA) were recently introduced which required lesser crown reduction when compared to Zirconia crowns and also satisfied the esthetic needs. The periodontal health at the vicinity is still unaddressed. Aim: To evaluate the periodontal health status of primary molars restored with PSSCs and Figaro crowns. Materials and Methods: This split mouth randomised clinical trial involved 25 children requiring bilateral pulp therapy in primary mandibular second molars between 6-9 years of age. Following pulp therapy, the teeth were randomly allocated into either NuSmile ZR or Figaro crown group. A single operator performed the treatment procedures for all the children to avoid operator variability. The children were recalled at 3, 6, 9 and 12 month intervals for assessment of periodontium. A research scholar who was not involved in the treatment procedure performed the periodontal assessments in the followup visits. Plaque accumulation was recorded using the Loe and Sillness Index. The collected data were subjected to statistical analysis. Results: At 3 months, 6 months, 9 months and 12 months follow ups, the mean PI scores and mean GI scores of the participants for Zirconia crowns were slightly lower than Figaro crowns but had statistically significance. (p>0.05). Conclusion: Within the limitations of the present study, both Zirconia crowns and Figaro crowns had reasonable amounts of plaque accumulation scores during the 12 month periodical follow ups.

The world is swiftly moving towards the renewable sources of energy owing to the depletion of fossil fuel reserves and detrimental impacts of green house gases on mankind and environment. Hydrogen is gaining more importance in the technical community around the globe as an energy carrier for the on-board vehicular applications. Solid state hydrogen storage is relatively emerged as an alternative option for storing hydrogen on-board as the conventional technologies viz., high pressure compression and cryogenic liquefaction failed to meet the storage goals. Profound research has been done to improve the hydrogenation properties of intermetallic compounds. The current paper aims at reviewing the latest advancements in the properties of intermetallic compounds for solid-state hydrogen storage applications viz., adsorption/desorption pressure and temperature, kinetics, hydrogen-storage capacity and cyclic stability.

Individuals with systemic conditions are at more risk of dental disease,have a greater prevalence and incidence of periodontal diseases. The aim of the study is to assess the periodontal status in medically compromised patients. It is a retrospective study regarding the association of periodontal disease status with systemic conditions in patients visiting a university dental hospital in Chennai in between June 2019 March 2020, the data of 86000 patients were reviewed and analysed. It included parameters - age, gender, periodontal disease status, systemic conditions. Chi-square test was used to detect the significance between the periodontal disease status and systemic conditions. In this study we observed that patients who were medically compromised were more prone to periodontal diseases.The most affected age group with systemic conditions and periodontal diseases was 46-90 years (74%). Males were found to be more affected (56%). Patients with diabetes and hypertension were more prone to periodontal diseases when compared with the other systemic conditions. Within the limits of this study, it is concluded that patients who were medically compromised were more prone to periodontal diseases. Patients with diabetes and hypertension were more prone to periodontal diseases when compared with the other systemic conditions.

Gingivitis is a non-destructive disease of inflammation of gums. Microorganisms inhabiting the oral biofilm anaerobes which release endotoxins when they penetrate periodontal tissues which result in periodontal damage. Dental caries occur as a result of the imbalance of the indigenous bacteria that accumulate onto the surface. Both dental caries and periodontal disease coincide with each other. Aim: This study aims to find the prevalence of carious lesions and non-carious lesions among patients with gingivitis. Materials and Methods: The study involves the assessment of patients visiting saveetha dental college. The clinical assessment of both perio-pathogenic, carious lesions, and the non-carious lesion was collected. The data was retrieved and was computed in excel format. It was then compared and analyzed statistically. Result: There were 59 males and 41 female patients in this study. Based on age the patients were grouped into 3 groups (20-29 age patients in group 1, 30-39 age patients in group 2, and 40-50 age patients in group 3). It was found that about 71%of the patient examined had gingivitis. Among the patients with gingivitis, about 51% of the patients had caries. Conclusion: The study concludes there is a close relationship between gingivitis and dental caries.
