Clinical
eliminated using dental floss on the vestibular surface. A polymerisation step was performed
for 40 seconds before a second, similar infiltration step was carried out. This minimises the surface porosityıı. To finish the session, the rubber dam
was removed and the surfaces were very carefully polished to prevent any future external discolouration (Fig ı0). Any excess was eliminated using dental floss and, if necessary, fine abrasive strips. All vestibular surfaces were polished using silicone tips. The microgeographyı2 was then copied before final polishing, using silicon carbon brushes (Enamel Plus; Shiny 4 (Micerium)), diamond pastes associated with a goat’s-hair brush (Enamel Plus; Shiny A and B (Micerium)) and aluminium oxide paste (Enamel Plus; Shiny C (Mice- rium)) associated with a felt disk. Considerable improvement in the aesthetic appearance of this patient’s teeth was achieved immediately (Fig ıı). An examination was carried out every six months to assess the aging of the resin over time. This minimally invasive treatment made a significant improve- ment in the patient’s smile, which caused
a considerable change in her personal and social relationships.
Clinical case two Initial examinations revealed that the patient was concealing the white fluorosis stains with her lower lip when she smiled (Fig ı2). • Fig ı3. Initial condition: vestibular view showing very slight porosity of the central incisors.
• Fig ı4. Results after 2ı days of external outpatient whitening.
• Fig ı5. Erosion procedure, after the operating field had been prepared. A palatal fixed orthodontic retainer made placing the rubber dam extremely complex.
• Fig ı6. Drying step, before the second erosion.

Conclusion The combination of an outpatient whitening treatment with a caries- infiltration treatment represents a therapy that is very appealing in cases of clinical fluorosis. In fact, the fluorosis lesions,
which appear as opaque white stains on the vestibular surfaces, may be masked simply by the infiltration of microporosities, which are responsible for the appearance of the lesions. Therefore, this superficial fluorosis
does not need the in-depth infiltration that was recently described by Attal et al.ı4. The combination of whitening and caries-infiltration shows a satisfactory result in these two patients. This therapy preserves the structures
of the tooth and does not cause any pain to the patient. They are also quick and simple for
the practitioner to carry out. Therefore, for all these reasons, this treatment should be considered as an alternative to micro-invasive treatments for concealing the white stains of fluorosis. However, long-term studies are
necessary to follow the progress of this therapy over time.
