- Assessment of the penetration of an endodontic sealer into dentinal tubules with three different compaction techniques using confocal laser scanning microscopyPublication . Barbero-Navarro, Ignacio; Velázquez-González, Diego; Irigoyen-Camacho, María Esther; Zepeda-Zepeda, Marco Antonio; Maurício, Paulo; Ribas-Perez, David; Castano-Seiquer, AntonioAdequate root canal sealing is essential for the success of endodontic treatment. There are numerous techniques available; identifying simple and efficient techniques is important to provide good patient care. The purpose of the study was to compare the maximum penetration depth and the percentage of sealant penetration of an endodontic sealer into dentine tubules using cold lateral condensation, continuous wave, and hybrid techniques, and to contrast the effectiveness of two different tapered gutta-percha master cones (0.02 and 0.04). A sample of sixty single root teeth was used. Six experimental groups were formed from the three filling techniques and the two tapered master cones. Images were acquired using a confocal laser scanning microscope. In the apical root third, the penetration percentage was higher in the hybrid compared with the continuous wave technique. The results indicated a higher penetration depth of hybrid compared with cold lateral condensation in the middle and coronal thirds, and in the apical third, a higher penetration was identified in the hybrid group compared with the continuous wave group. No significant differences in penetration were found comparing 0.02 with 0.04 taper gutta-percha groups. The coronal cross-sections presented a higher penetration than the apical third sections. In conclusion, the hybrid technique a had higher maximum sealer penetration than the continuous wave in the apical third, and the coronal third hybrid and continuous wave had a higher penetration than cold lateral condensation.
- Oral health in migrants children in Melilla, SpainPublication . Kizi, Gunel; Barata, Ana Raquel; Ventura, Irene; Flores-Fraile, Javier; Ribas-Perez, David; Castaño-Seiquer, AntonioNumerous developing countries’ socioeconomic and political issues resulted in a significant migratory phenomenon, which poses a health burden for the nations that receive migrant populations. Often, the greatest age group of migrants is children and teens. Oral problems are one of the most common reasons that immigrants in the receiving nations visit the healthcare system. Cross-sectional research was conducted on children and teenagers housed at the Temporary Stay Center for Immigrants (CETI) of the Autonomous City of Melilla (Spain) with the aim of identifying the state of the oral cavity of these group of migrants. Information on the condition of the research group’s oral cavity was gathered using the World Health Organization’s standards. The research comprised all of the children and teenagers who were enrolled in the CETI for a defined period of time. A total of 198 children were assessed. It was determined that 86.9% of the youngsters were of Syrian descent. There were 57.6% males and a 7.7 (±4.1) average age. The average caries index for children under the age of six was dft =6.4 (±6.3), and for children aged six to eleven, it was 7.5 (±4.8), taking into account both the temporary and permanent dentition, and for children aged twelve to seventeen, it was 4.7 (±4.0). A total of 50.6% of children between the ages of 6 and 11 needed extractions, compared to 36.8% of children under the age of 6. The population under study had a significant incidence of sextants where bleeding occurred during periodontal probing (mean 3.9 (±2.5)), according to an examination of the community periodontal index (CPI). It is crucial to study the oral cavity status of refugee children when designing intervention programs to improve their oral health and provide health education activities that favour the prevention of oral diseases.
