Objective: To compare the pulp vitality of deciduous molars before and after selective caries removal (SCR) or nonselective caries removal to hard dentin (NSCR) over one year, using oxygen saturation percentage (%SaO2). Material and Methods: Deciduous molars with deep occlusal/proximal-occlusal caries lesions were randomized to SCR (n=22) or NSCR groups (n=22). After the caries removal, the teeth were protected with calcium hydroxide cement and restored with composite resin (Filtek Z250). The pulp condition diagnosis was evaluated at baseline, immediately after caries removal, and follow-up (7 days, 1-, 6- and 12-months) by %SaO2. Pulp exposure and pulp necrosis were primary outcomes, and %SaO2 was secondary. Results: Intraoperative pulp exposure occurred in four teeth of the NSCR group (18.2%) and one tooth of the SCR group (4.5%) (p>0.05). Two cases of pulp necrosis occurred in the NSCR group (10%). No difference in %SaO2 pulp was observed in the inter-and intragroup comparison over time (p>0.05). Conclusion: Advantageously, the %SaO2 minimizes preoperatory pulp vitality diagnosis subjectivity before SCR/ NSCR treatments. Furthermore, the pilot study results suggest the pulp response of deciduous molars, when evaluated by clinical, radiographic, and pulp %SaO2 seems not to differ between teeth treated with SCR or NSCR.

This systematic review aimed to investigate if there is a better interceptive treatment for palatally displaced canines (PDC) in the mixed dentition stage. The PubMed/MEDLINE, CENTRAL, Scopus, and EMBASE databases were searched for randomized clinical trials related to the research topic. The gray literature and reference lists were also assessed. Network meta-analysis was conducted to analyze the effects of different approaches on PDC eruption. The surface under the cumulative ranking area was calculated to rank the treatments. The certainty of the evidence was evaluated using the GRADE approach. Of the 892 eligible studies, 18 were selected for full-text analysis and 9 for meta-analysis, involving 506 participants and 730 PDC, to compare 9 approaches. The proportion of erupted PDC was significantly higher for all interceptive treatments compared with control (no intervention). Furthermore, the proportion of erupted PDC was higher in patients subjected to rapid maxillary expansion (RME) than those who underwent double extraction of primary canine and primary molar (relative risk (RR) = 2.68 ICr95%: 1.12–9.35). A higher proportion of erupted PDC was found for RME (RR = 3.07 ICr95%: 1.31–10.67), RME plus use of transpalatal arch (TA) plus extraction of primary canine(s) (EC) (RR = 1.43 ICr95%: 1.09–1.95), EC plus use of cervical pull headgear (RR = 1.38 ICr95%: 1.11–1.79), and EC plus use of TA (RR = 1.36 ICr95%: 1.00–1.9) than for EC. RME was most likely to be considered as the best interceptive treatment. Overall, the certainty of the evidence was considered low due to imprecision and indirectness. In conclusion, no intervention in the mixed dentition stage is the worst choice for PDC.

La sistematización de información productiva es una de las acciones que realiza el INTA desde su creación. A fin de 2019 se incorporaron las Plataformas de Innovación Territorial (PIT) como ámbitos para identificar y priorizar problemas y oportunidades que aporten a la innovación territorial. Su propósito es gestionar con otras instituciones y actores del territorio para el desarrollo de procesos y productos que sirvan de insumo de las políticas públicas. Para ello deben contribuir a mantener actualizados los diagnósticos y estrategias territoriales con visión prospectiva. Este trabajo se propone contribuir a conformar una capa base de información con estimación de superficies de actividades intensivas del territorio, así como desarrollar una metodología situada para mantener actualizados los datos, combinando técnicas de teledetección con relevamiento a campo de observación directa. En esta etapa se puso el foco en las principales producciones intensivas de los partidos costeros: San Nicolás, Ramallo, San Pedro, Baradero y Zárate: fruticultura, horticultura intensiva (a campo y bajo cubierta), viveros y avicultura. La generación de esta información será de utilidad como diagnóstico del territorio para la gestión y la investigación. EEA San Pedro Fil: Delprino, Maria Rosa.

Objetivo: Avaliar a progressão de cárie e a necessidade de reintervenção em lesões oclusais ICDAS 4 após diferentes tratamentos. Material e Métodos: A amostra consistiu de prontuários de crianças atendidas em ambiente público que apresentavam pelo menos uma lesão oclusal ICDAS 4 em molares decíduos e/ou permanentes. As imagens radiográficas de lesões ICDAS 4 na primeira e última consultas foram classificadas como ausência de radiolucidez, imagem radiolúcida na junção esmalte-dentina, em metade externa ou interna da dentina. A necessidade de retratamento após diferentes tratamentos (não invasivo – aplicações tópicas de flúor, orientações de higiene e dieta, micro-invasivo – selante resinoso ou invasivo – restauração) foi avaliada por meio da revisão dos registros clínicos e radiográficos. A necessidade de retratamento foi definida como qualquer complicação que requer intervenção (por exemplo, progressão da lesão, perda total do selante ou falha na restauração). O modelo de regressão de Poisson foi utilizado para investigar a associação entre as variáveis individuais e dentárias e o desfecho. Resultados: Entre as 111 lesões em 81 pacientes, a maioria (73,0%) das lesões eram em molares decíduos. A maioria das lesões (52,3%) não exibiu radiolucidez, enquanto que 29,7% apresentaram radiolucidez em metade externa de dentina. O tempo de acompanhamento médio foi de 18,8 ± 6,5 meses. Após o acompanhamento, 82,9% das lesões não necessitaram de retratamento. A prevalência de lesões ICDAS 4 que não necessitaram de retratamento foi maior entre as lesões com radiolucidez em dentina (p=0,01). Conclusão: A maioria das lesões oclusais ICDAS 4 não requerem reintervenção, especialmente aquelas que exibem radiolucidez em metade externa da dentina. Objective: To assess the caries progression and the need for reintervention on occlusal ICDAS 4 lesions after different treatments. Material and Methods: The sample consisted of records of children treated in a public setting who had at least an occlusal ICDAS 4 lesion in primary and/or permanent molars. The radiographic images of ICDAS 4 lesions at the first and last appointments were classified as absence of radiolucency, radiolucent image at the enamel–dentin junction, at the outer half or inner of the dentin. The need for retreatment after different treatments (non-invasive - topical fluoride applications, oral hygiene instructions and dietary guidance, micro-invasive - resin-based sealant, or invasive - restoration) was assessed by reviewing clinical and radiographic records. The need for retreatment was defined as any complication requiring mending (e.g., caries progression, total loss of sealant, or restoration failure). The Poisson regression model was used to investigate the association between individual and tooth-related variables and the outcome. Results: Among the 111 lesions in 81 patients, most (73.0%) lesions were in primary molars. Most lesions (52.3%) did not exhibit radiolucency, whereas 29.7% had radiolucency at the outer half of the dentin. The mean follow-up was 18.8 ± 6.5 months. After follow-up, 82.9% of the lesions did not require retreatment. The prevalence of ICDAS 4 lesions that did not need retreatment was higher among lesions with radiolucency at dentin (p=0.01). Conclusion: Most occlusal ICDAS 4 lesions did not require reintervention, especially those exhibiting radiolucency in the outer half of the dentin.
