Proximal caries in anterior teeth is big challenges to dentist because it's in esthetic zone , SO the shade selection should be accomplished prior to rubber dam isolation to prevent improper color matching that may result from dehydration and elevated values.



Img.1 - frontal view in occlusion showing the proximal carious lesion in multiple teeth .

Img.2 - palatal view showing the carious lesion more clearly .

Img.3 - frontal view showing the proximal carious lesion in four anterior teeth .

Img.4 - isolation in such case is mandatory to be work in clean field .

Img.5 - isolation provide more visible area to the target ( the field is ready to work on ) .

Img.6 - another view with further magnification .

Img.7 - frontal view after removing the caries .

Img.8 - palatal view showing the cavities after caries removing .

Img.9 - another view showing the cervical enamel free from caries and clean .

Img.10 - total etching with 37% phosphoric acid .

Img.13 - light curing .

Img.14 - palatal view before finishing and polishing . 

Img.15 - frontal view immediately after finishing .

Img.16 - the filling is marked , don't worry , wait the rehydration.

Img.20 - palatal view after rehydration ( one month control ). 

Img.21 - frontal view showing the result after rehydration and color matching .

Img.22 - Before and After .

Conclusions

When the teeth dehydrate , the air replaces the water between the enamel rods , changing the refractive index that makes the enamel appear opaque and white . If the correct shade color is selected before isolation with rubber dam , don't worry , just trust to rehydration .
