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.

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 
Las fracturas radiculares son vistas con más frecuencia en estos días, afectando con mayor frecuencia a los premolares superiores posiblemente por su particular conformación anatómica. También parecen, antaño, haber sido sub diagnosticadas. 
El “TAC” -Tomografía axial computarizada- ha cobrado un inusitado interés en la población odontológica. De hecho, es el segundo tema más requerido en el sitio de Odontoclínica en el último año. Lo anterior podría se consecuencia del auge de los implantes en nuestro medio, aunque también, resulta una herramienta de mucho valor en otros planos como Cirugía. Tanto la Bibliografía, como la publicación sobre “Historia de la Tomografía” han sido una cooperación del Dr. Gustavo Moncada Cortés. ( gmoncada@adsl.tie.cl ). Int J Comput Assist Radiol Surg. 2010 Jan;5(1):57-67. Epub 2009 Jul 24. A fully 3D work context for oral implant planning and simulation. Chiarelli T, Lamma E, Sansoni T. Dipartimento di Ingegneria, University of Ferrara, Via Saragat 1, 44100 Ferrara, Italy. tommaso.chiarelli@unife.it Abstract PURPOSE: Most software systems for oral implantology are based on a two-dimensional multi-view approach, often accompanied with a surface rendered model. Usually they are affected by common errors like anisotropy of the volume and distortion on measurements. A more integrated and realistic 3D approach for implant surgery is desirable in order to gain a deeper and surer knowledge of patient’s anatomy before inserting the implants, thus reducing the risk of damaging surrounding structures. METHODS: We present a 3D software system for oral implant planning where computer graphic techniques have been used to create a smooth and user-friendly fully integrated 3D environment to work in. Both volume isotropy and correctness in measurements are obtained through slices interpolation to achieve, respectively, an isotropic voxel and the freedom of choosing arbitrarily, during the planning, the best cross-sectional plane. Correct orientation of the planned implants is also easily computed, by exploiting a radiological mask with radio-opaque markers, worn by the patient during the CT scan. RESULTS: Precision in measures was validated by considering several different scans and comparing the measures achieved with the ones got through the common methodology. It has been also calculated error percentages, algorithms efficiencies, and performances. Precision achieved outperforms usual DentaScan multi-view approach one, and it is comparable with or better than that obtained by the DentalVox tool (from 0.16 to 0.71% error in measures). CONCLUSIONS: The proposed software system provides a user-friendly, correct and precise work context for oral implant planning, avoiding similar software common errors. The 3D environment can be also exploited in the final surgical phase, in order to provide a flapless surgical guide, through the use of an anthropomorphic robot.

Department of Orthodontics, University of Rome Tor Vergata, Italy. AIM: This was to correlate the dosimetric evaluation with high diagnostic accuracy by suggesting a protocol that significantly reduces the dose administered by a Dentascan exam without affecting diagnostic accuracy.

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.
