There are various situations when we see Class V restorations, that are either due to caries or Toothbrush Trauma. Most of the lesions get noticed by the patient themselves during brushing, or are indicated by the people who see the ugly lesions. Most common etiology of such lesions are:
1. Poor Oral Hygiene
2. Hard Brush
3. Vigorous Brushing Technique, which employs Brushing along the gum margin, 90 degrees to the surface of the tooth
4. Food Impaction, if there are removable denture clasps in the vicinity of the area
Such lesions are very easy to treat, and the most common choice of material is the Composite. With the advent of nanohybrid composites, and their easy availability, these materials are actually catching up with the normal dental practitioners.
Composites, are resin modified filling materials, that not only bond chemically with the available tooth structure, but are also aesthetically pleasing. A wide variety of shade selection, and natural staining techniques with the restoration, composites stand very suited to produce excellent results.
Class V cavities were located on the facial aspect of 34 and 35, in the cervical areas, the cavities were prepared by the following steps:
1. Placement of retraction cords around 34 and 35
2. Since there was no catch on probing the carious lesions, they were still cut using a round bur.
3. The margins along the lesion were cut so that there was a gradient shift in the cross sectional area of cutting and when it is to be filled, the margin of restoration should blend with the tooth surface.
During preparation, Isolation was not important, but after the cavity preparation, the cavity was kept isolated. It was etched with a 37% Phosphoric acid, and rinsed thoroughly with water, so that there were no residue on the etched surface. Bonding/Primer application was done, and it was light cured, followed by Composite placement.
