Ítem Pénfigo vulgar y su manejo integral: Reporte de dos casos y revisión de literatura(2021-04-15) Boza Oreamuno, Yadira Vanessa; González Quesada, JorgeEn la cavidad oral se pueden presentar lesiones en gíngiva que no están asociadas a placa bacteriana, las cuales requieren de un adecuado diagnóstico y tratamiento. La gingivitis descamativa está usualmente relacionada con desórdenes mucocutáneos, como el pénfigo vulgar (PV), donde las lesiones orales incluyendo las lesiones gingivales, pueden preceder las lesiones cutáneas. El manejo es multidisciplinario y el tratamiento incluye terapia farmacológica tópica y sistémica, se requiere un adecuado control de la placa bacteriana por parte del paciente y una estricta supervisión en el tiempo por parte del profesional para el mantenimiento y estabilidad de los tejidos gingivales. Se presentan dos casos clínicos de pacientes con diagnóstico de PV los cuales fueron manejados de manera oportuna e integral para controlar y estabilizar el factor sistémico y local.Ítem Dental caries in 12-year-old schoolchildren who participate in a preventive and restorative dentistry program(2021-06-09) Ramírez Chan, Karol Gabriela; Gómez Fernández, AdriánSince 2013, the Faculty of Dentistry of the University of Costa Rica has provided a preventive and restorative oral health program at Carmen Lyra Public School. The first generation of students that received dental care from this project were examined in 2019 for caries status. A total of 62 twelve-year-old schoolchildren were examined (31 boys and 31 girls). First, all teeth surfaces were cleaned with a brush and then rinsed. Subsequently, examination was performed in each person by a calibrated examiner using the International Caries Detection and Assessment System (ICDAS). Prevalence of dental caries was 59.7%. ICDAS code 2 was the most prevalent (68.8%), followed by 1 (19.3%), 5 (4.5%), 3 (3.5%), 6 (2.5%), and 4 (1.4%). Regarding number of carious surfaces, the highest prevalence was observed in the occlusal surfaces (77.3%), followed by the vestibular (13.9%), mesial (4.2%), palatal/lingual (4,1%) and distal (0.5%). Of these carious surfaces, 7% were caries associated with restorations and were present only on the occlusal surfaces. Boys had more cavities than girls (54.1% compared to 45.9%), however, this difference was not significant. Regarding the condition of restorations in teeth, 92 dental restorations (resin or amalgam) were found in the population studied and were well adjusted. Most of these restorations were found on the occlusal surfaces (82.6%), followed by vestibular surfaces (8.7%,) palatal/lingual (5.4%) surfaces, mesial surfaces (3.3%), and no restorations were detected on the distal surfaces. Sealants were identified in 11.3% schoolchildren; 98% were identified on the occlusal surfaces and the other 2% were found on the palatal/lingual surfaces. DMFT Index was 1.6±0.71. The prevalence of dental caries in this sample was low compared to other studies in twelve-year-old schoolchildren in Costa Rica. This may suggest that the oral health program had a positive impact in the studied population.Ítem Prevalence of Dental Caries Among Costa Rican Male Students Aged 12-22 Years Using ICDAS-II(2021) Gudiño Fernández, Sylvia; Gómez Fernández, Adrián; Molina Chaves, Katherine; Barahona Cubillo, Juan; Fantin, Romain Clement; Barboza Solís, CristinaObjective: Dental decay is a public health challenge in Low- and Middle-Income Countries, particularly for young people, often confronted to healthcare access barriers. The aim of this study was to determine the prevalence and severity of dental caries among young male students in Costa Rica. Study design: A cross-sectional study was performed in 428 Costa Rican male students aged 12-22 years, who attended a nonprofit social welfare boarding school in 2019. A clinical examination was ran by three calibrated examiners following the International Caries Detection and Assessment System (ICDAS-II). Results: Caries prevalence was estimated at 83%, 15% have lost a tooth due to dental decay, 61% have at least one filled tooth, 36% have at least one filled and decayed tooth. The most frequent caries lesions were codes 2-Inactive (46.7%), and code 1-Inactive (23.8%). DMFT indicated a mean index using ICDAS-II 1-6>0 codes of 7.89. Using ICDAS-II 3-6>0 as threshold, the index decreases to 3.94. Finally, the lower and upper first permanent molars were found to be the most affected teeth. Conclusions: Dental caries experience represents a significant public health burden in young people, requiring better access to public dental healthcare.Ítem The Oral Microbiota: a Literature Review for Updating Professionals in Dentistry-Part II(2021) Barboza Solís, Cristina; Acuña Amador, Luis AlbertoIn the first part of this literature review, published in October 2019 in this journal, we summarized the conceptual background of the oral microbiota, and the main methods used in microbiology to characterize oral organisms. We also presented the most studied bacteria species in the oral microbiota. In this second part, we will discuss the evidence regarding the biological plausibility linking the oral microbiota dysbiosis and systemic diseases, as well as the main factors and mechanisms suspected in this association.Ítem Correlación del diagnóstico clínico e histopatológico de lesiones de la mucosa oral entre 2008-2015 en la Universidad de Costa Rica(2020) Boza Oreamuno, Yadira Vanessa; López Soto, AndreaRESUMEN: El objetivo de este estudio es determinar la concordancia existente entre el diagnóstico clínico e histopatológico de las lesiones en la mucosa oral en la Facultad de Odontología de la Universidad de Costa Rica (UCR). Es un estudio retrospectivo de 261 informes de lesiones orales recuperados del archivo de biopsias de la Facultad de Odontología de la UCR de 2008 a 2015, fueron analizados 165 reportes que cumplian con los criterios de inclusión. La concordancia entre el diagnóstico clínico e histopatológico fue verificada mediante el test Kappa. Del total de los informes, 96 (36.8%) no contaban con alguna hipótesis diagnóstica. La concordancia con la primera hipótesis diagnóstica se presentó en 114 (69.1%) casos, el valor de kappa fue de 0.663 (concordancia sustancial). Las lesiones premalignas presentaron una concordancia excelente (kappa=0.902). La concordancia del grupo de lesiones proliferativas no neoplásicas fue moderada (kappa=0.504) y las condiciones dermatológicas y autoinmunes con una concordancia insignificante (0.157). La concordancia se produjo en la mayoría de los pacientes investigados con un valor correspondiente a un acuerdo sustancial, sin embargo, se debe mejorar el porcentaje de informes que no contaban con hipótesis clínica.Ítem Manifestaciones bucales de la enfermedad celiaca y alergia al trigo: Reporte de tres casos y revisión literatura(2018) Boza Oreamuno, Yadira Vanessa; Rugama Flores, María FernandaLa Enfermedad Celíaca (EC) es una enfermedad sistémica inmunomediada, provocada por el gluten y prolaminas relacionadas, en individuos genéticamente susceptibles. Se caracteriza por manifestaciones clínicas dependientes del gluten, anticuerpos específicos de EC, haplotipos HLA DQ2 o DQ8 y enteropatía. La mayoría de los pacientes son asintomáticos o con manifestaciones leves. Afecta principalmente el sistema gastrointestinal causando síntomas y signos como diarrea, dolor abdominal recurrente y distensión abdominal; además manifestaciones extradigestivas. Los pacientes con EC pueden tener manifestaciones bucales que incluyen estomatitis aftosa recurrente (EAR), hipoplasia del esmalte, glositis atrófica, entre otras. El diagnóstico de EC se basa en la historia clínica, serología, endoscopía e histología. Existen otras entidades que deben diferenciarse de la EC, como la sensibilidad al gluten no celíaca y la alergia al trigo. El objetivo de este trabajo es presentar tres pacientes con antecedentes de EAR y otras manifestaciones clínicas asociadas al diagnóstico precoz de EC y alergia alimentaria
