Objectives: The objective of this study was to relate the CPOD index and limitation of brushing teeth in 12-year-old schoolchildren of the El Sagrario parish in 2016. Materials and Methods: The present study has a quantitative, descriptive, retrospective relational approach. The sample consisted of 155 observation files consisting of: registration number, age, sex, parish, CPOD index and limitation to brush teeth. Results: It was represented by tables and bar graphs; used the statistical analysis of Tau_b Kendall. Both sexes presented a very low level with respect to the DMFT index, in terms of impact and severity in brushing their teeth, the male sex presented a limitation with a lower percentage than the female sex. Conclusion: There was a very low correlation between the study variables.

Introduction: The post-exodontic alveolar atrophy requires quality bone regeneration techniques, and therefore, it is necessary to apply platelet concentrates, which are bioactive agents in the process of preserving the alveolar bone. The use of platelet concentrates proved to be an excellent　osteoinducer since it leads to three important effects for maintaining bone structure. Objective:　To analyze the use of platelet concentrates in post-exodontic bone regeneration. Materials and　methods: A descriptive, explanatory study. A narrative review in which data was collected from 26 scientific articles published in scientific databases such as PubMed, Redalyc, ScienceDirect, and　Ovid between 2012 and 2022. Conclusions: Platelet concentrates are physiological materials that　speed up the healing time of post-extraction wounds. They are autologous since they are taken　from the p...
