¿ A alguien le parece a primera vista que la primera fotografía muestra una boca relativamente limpia? Pues es posible que si, sin embargo, una magnificación del canino inferior derecho, exhibe un brackett que prácticamente está siento sobre pasado por la acumulación de saburra. (Ya lejos de ser placa bacteriana…). [...] 
Una erosión más que engrosa el número día a día. La foto superior, muestra un primer molar superior izquierdo con una restauración antigua y una erosión sobre la cúspide mesio vestibular. Los brillos que parecen atípicos, corresponden a la aplicación de un Flúor barniz el que debería [...]
Un caso de Fluorosis, de los pocos que me toca ver por estos días. 
Foto 1. Caso previo, después de aislar con dique de goma y limpiar las superficies a tratar con escobilla y piedra pómez. Foto 2. Mesurada aplicación de ultrasonido sobre los surcos del molar con una punta acondicionada para estos efectos. Foto 3. Aplicación de ácido ortofosfórico al 35% [...]
Llama la atención que un tema tan relevante como la prevención -en este caso desde la óptica del Fluor- no merezca mayor investigación, la blibliografía no es muy abundante, (si la comparamos con la investigación en materiales restauradores) pero si, concluyente.

Federal University of Alagoas, Maceió, AL, Brazil. jilreis@uol.com.br The purpose of this study was to evaluate the effect of the application of fluoride products on the development of enamel caries in deciduous teeth. A total of 108 deciduous teeth were chosen for the study. Acid-resistant varnish was applied on the teeth, leaving only one area of 5 mm x 1 mm of dental enamel exposed. The teeth were allocated randomly to one of the following groups: 1) control – toothpaste without fluoride; 2) 1.23% fluoride gel; 3) Duraflur fluoride varnish; 4) Duraphat fluoride varnish; 5) Fluorniz fluoride varnish; 6) Fluorphat fluoride varnish; 7) varnish with Duofluorid; J Indian Soc Pedod Prev Dent. 2007 Oct-Dec;25(4):157-63.

Jeevarathan J, Deepti A, Muthu MS, Rathna Prabhu V, Chamundeeswari GS. Department of Pediatric Dentistry, Meenakshi Ammal Dental College and Hospital, Chennai, Tamilnadu, India. dr_rathan@rediffmail.com Dental caries is one of the most prevalent infectious diseases and although of multifactorial origin, Streptococcus mutans is considered the chief pathogen in its development. Fluoride is one of the most effective agents used for the reduction of dental caries apart from oral hygiene maintenance. AIMS: The aim of this study was… Continue reading Fluor. Bibliografía |

12% silver fluoride diamine (Cariestop); 9) children’s fluoride toothpaste (500 ppm). The tested products were applied on the teeth according to the manufacturer’s recommendations and the teeth were stored in a moist environment for 24 hours. Each group of teeth was then subjected to a pH cycling model for 14 days, after which the teeth were cut through the center for an analysis of the depth of the carious lesion by polarized light microscopy. Comparisons were made between the treatments and the control group. The mean lesion depth values were 318 microm +/- 39 (control), 213 microm +/- 27 (fluoride gel), 203 microm +/- 34 (Duraflur), 133 microm +/- 25 (Duraphat), 207 microm +/- 27 (Fluor-niz), 212 microm +/- 27 (Fluorphat), 210 +/- 28 (Duofluorid), 146 +/- 31 (Cariestop) and 228 +/- 24 (fluoride toothpaste). None of the products used here was able to completely prevent the formation of lesions. The highest cariostatic effect was achieved by fluoride varnish Duraphat and the lowest by the fluoride toothpaste.
