El objetivo de este estudio fue 1) determinar la AD en pacientes con periodontitis antes del primer paso y después del segundo paso del tratamiento de la periodontitis (tratamiento periodontal no quirúrgico) y 2) recopilar características sociodemográficas y clínicas de la población estudiada. Métodos: se invitó a participar a pacientes con periodontitis que nunca habían recibido instrumentación subgingival, que asistían a la Clínica de Periodoncia de la Facultad de Odontología de la Universidad de Costa Rica. Del expediente electrónico se obtuvo la siguiente información: estadio periodontal, Índice de Placa (PI) e Índice de Sangrado Gingival (ISG). Se aplicó un cuestionario antes del primer paso y después del segundo paso del tratamiento de la periodontitis. Los datos recolectados incluyeron: factores sociodemográficos, hábitos de tabaquismo, condición de exfumador, dolor y la Escala de Ansiedad Dental de Corah Modificada (MDAS). Resultados: 51 pacientes completaron el estudio, 19 hombres y 32 mujeres, con un promedio de edad de 46 ± 11,16 años. La mayoría de los participantes refirió haber terminado la enseñanza media (37,3%). En cuanto al hábito de fumado, el 46% de los participantes eran no fumadores. De los no fumadores, el 7,8% eran exfumadores. El dolor máximo del paciente en el último mes disminuyó después de completar el segundo paso del tratamiento de la periodontitis (p=0,002). El diagnóstico periodontal más prevalente fue el Estadio III seguido del Estadio II. El PI medio fue del 61,4 % y el GBI medio fue del 39,5 %. El miedo al sonido de los instrumentos rotatorios y los raspadores ultrasónicos mejoró después del tratamiento periodontal. La AD se redujo en comparación con el valor inicial, según la puntuación total del MDAS y para todas las sub-puntuaciones del MDAS. Conclusión: la autopercepción de la AD mejoró en el trascurso del tratamiento periodontal en nuestro entorno clínico.","PeriodicalId":272900,"journal":{"name":"Revista Facultad de Odontología","volume":"60 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139256624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This situation impacts their health situation. This study aimed to know the perceptions about health (physical, mental, and oral) of four women who work in prostitution in Medellin, based on their life experiences and those related to their social context. Methods: qualitative research with an ethnographic approach was conducted to analyze the situations mentioned. Four women participated, two Venezuelans and two Colombians, and semi-structured interviews were conducted. Qualitative content analysis was performed, which allowed the generation of four categories (mental health, oral health, general health, and quality of life). Results: her discourses made it possible to elucidate the connection between the living conditions and the health situation. The lack of job opportunities, a migratory process of profound economic and social changes, and a Colombia with inequities and barriers to access to health and social services are determining processes of a general and singular order of the precarious conditions of oral health and general. Conclusions: the participating population is in a situation of social and health vulnerability, which shows the need for public policies and strategies based on the social reality that contribute to generating equity in health.","PeriodicalId":272900,"journal":{"name":"Revista Facultad de Odontología","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121058647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to carry out a literature review with emphasis on clinical implications and treatment alternatives of a COA through an update and review of information of interest. Methods: a literature review was carried out through a collection and analysis of bibliography of oroantral communications and the comparison and treatment alternatives. Discussion: various techniques have been proposed for the management of an AOC, among which are local flaps, as well as the use of biomaterials, which have given favorable results in closing the defect. Conclusion: the treatment of an AOC has as purpose to prevent its progression to an AFO, the development of sinusitis and/or that the defect increases; To do this, the clinician must be familiar with the various techniques based on the patient's needs.","PeriodicalId":272900,"journal":{"name":"Revista Facultad de Odontología","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122621598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: we distributed 30 new endodontic files in three groups.

We measured the time to file fractureand the length of the fractured fragment. ANOVA analysis was used, followed by the Tukey test for multiple comparisons, with a significance level of 5% (P < 0.05). Results: the mean time in seconds until the file fractured was 170.7 ±15.1 for AFB files, 110.4 ±26.8 for X1B, and 163.3 ±22.9 for RB files. This difference was statistically significant when comparing X1B to AFB (p: 0.000) and X1B to RB (p: 0.000). However, there are no statistically significant differences between RB and AFB (p:0.739).

Methods: analytical cross-sectional study, the angle formed between the plane (Silla-Nasion) (U1-NS) and the inclination of the upper incisor and the angle between axial inclination of the lower incisor and mandibular plane (Go-Gn), were measured in 47 initial and final lateral radiographs of patients who finished orthodontic treatment. The anterior sector PAR index was applied to pretreatment (T0), posttreatment (T1) and follow-up (T2) casts. Statistical analysis was performed using frequency and percentage distributions, T test, Anova I, Anova II and Manova; significance p = 0,05. Results: no association was found between upper and lower incisor inclination, alignment stability and PAR weighted score between T2-T1 (p> 0,05).

Although the most common failure mechanisms have been established for motorized endodontic files, the information is scattered, making it difficult to develop clear research trends. Methods: a scoping review was carried out using Scopus, Dimensions.ai, Web of Science, and Science Direct databases to answer screening questions related to the predominant fracture mechanism in NiTi files, test types, and equipment used for experimentation and to identify the most active authors.Results: using the general search terms, 432 research papers were found, of which 75 were finally selected after eliminating duplicates and applying exclusion criteria. Conclusions: typical failure mechanisms for rotatory and reciprocating files were identified based on the panoramic review and bibliometric indicators. Also, the standard mechanical tests for endodontic files and the characteristics of their assemblies were summarized. The most active authors in the area and their nationality were tagged.
