Estimado Editor, Hemos leído el artículo de revisión titulado “Flúor y fluorosis dental” de Martínez-Cántaro N, et al.,1 publicado en su importante Revista Odontológica Basadrina (2021;5(1):75-83). Claramente, es un artículo de revisión de suma importancia odontológica que pretende sintetizar los beneficios y desventajas de la exposición al flúor, a través de sus diferentes formas, y el impacto que se tiene sobre la salud humana, principalmente en la forma de fluorosis dental. Queremos felicitarlos y a la par hacer algunas contribuciones. El flúor (F), nombre que proviene del latín fluere «fluir», descubierto por el químico Carl Wilhelm Scheele en 1771 y aislado en 1886 por el ganador del Premio Nobel de Química en 1906, Henri Moissan, nos hace alusión, por su etimología, a sus características físicas: un gas corrosivo de coloración amarillo-pálido. Además, ...

Objective. To report the epidemiological profile and the presence of polymorphisms of the IFR6 (rs2235371) and TGFA (rs3771494) genes, in individuals with non-syndromic cleft lip and palate. Methods. Case series study, focused on individuals with orofacial clefts, referred to the School of Dentistry of Durango, Mexico, for review and assessment within the period from January 2018 to December 2019. Information of interest for the study was obtained on the characteristics of pregnancy and family history of the mothers of the individuals. For the analysis and description of the data, the statistical software R Studio was used. Results. There was a higher frequency of men (67%), most of the individuals had the diagnosis of cleft lip and palate at birth (75%), the extension of the complete affection (75%), the left side affected (63%), and corrective surgeries (62%). Only 4% were exposed to m...

Objective. The purpose of this study was to compare the changes by conical beam computed tomography in the condylar positioning of Class III patients before and after a sagittal osteotomy of the bilateral mandibular ramus in Class III indicated for mandibular retroposition. Methods. Thirty patients were analyzed, 16 women and 14 men with an age range of 15 to 40 years and untreated Class III dentofacial deformity who were attended by diagnostic consultation during the period from 2013 to 2016 at the “General Ignacio Zaragoza” Regional Hospital (CDMX, Mexico), performing measurements of the condylar position in three stages: presurgical, intermediate (4 days after surgery) and final (9 months after surgery), in two planes: sagittal section and coronal section. Results. No significant difference was observed in the anterior, central and posterior spaces before (2.56 ± 0.55 mm; 1.78 ±...

Objective: The objective was to estimate the prevalence of temporomandibular disorders (TMD), in students of the Faculty of Dentistry. Material and Methods: This was a descriptive, observational, prospective, cross-sectional study. The study included 18 to 28-year-old students from the Faculty of Dentistry of the Universidad Juárez del Estado de Durango, México, attending the 1st to 8th semester of the 2018-A school year in whom the simplified Fonseca anamnestic index (sFAI) was applied to characterize TMD. The sample size was determined using the Epi InfoTM software, obtaining a total sample size of 263 individuals. The R Studio (2019) statistical package was used to describe the data. Results: The prevalence of TMD in the study population was 63%, with a mild disorder being the most prevalent in 44%. The Chi2 test showed statistically significant differences between sex and TMD (p = ...
