Golf Ball

1. The rough bands of depressions are arranged in a parallel, spaced relationship on the outer surface of the golf ball.
2. Preferrably the rough bands comprise a plurality of spaced depressions in the outer surface of the golf ball.
3. Similarly, the geometry of the spiral depressions 16 also contributes to and improves the aerodynamic of the golf ball.

Tooth Surfaces

1. Sealants form a protective barrier by bonding to tooth surfaces and covering the natural depressions and grooves.

Teeth Surfaces

1. This plastic resin bonds into the depressions and grooves (pit and fissure) of the teeth surfaces making them smooth and much easier to clean by brushing.

Tooth Decay

1. These depressions and grooves accumulate plaque, which promotes tooth decay.
2. Food and bacteria build up in these depressions, placing your child in danger of tooth decay.
3. Dental sealants fill in these depressions, preventing bacterial formation that causes tooth decay and other damage.

Enamel

1. The painted on liquid sealant quickly bonds into the depressions and grooves of the teeth forming a protective shield over the enamel of each tooth.
2. The painted on liquid sealant quickly bonds into the depressions and groves of the teeth forming a protective shield over the enamel of each tooth.

Dimples

1. In use, the ball is arranged such that the rough bands of depressions or dimples are disposed substantially parallel to the ground.
2. The dimples may also comprise spiral depressions directly on the spherical surface of the ball.

Surface

1. Cut glass: Any glass whose surface has been cut into facets, grooves and depressions by a large, rotating wheel.
2. Look for depressions around vent pipes where water can collect and begin leaking through cracks in the surface.
3. Inlays fill cavities or depressions while onlays lie on the surface of the tooth, building up damaged cusps.

Form

1. The spiral shaped depressions are arrayed to form a generally rounded or circular perimeter shape.

3. This plastic substance bonds into the depressions and grooves of the teeth and acts as a barrier, protecting enamel by "sealing out" plaque and acids.

Food Particles

1. Tooth sealants protect these susceptible areas by sealing the grooves and depressions, preventing bacteria and food particles from residing in these areas.

Calderas

1. Depressions such as Crater Lake, formed by collapse of volcanoes, are known as calderas.
2. Calderas are different from craters, which are smaller, circular depressions created primarily by explosive excavation of rock during eruptions.

1. We apply a plastic resin to the chewing surfaces of your permanent teeth, bonding into the depressions and grooves of the premolars and molars.
2. When the teeth are developing, depressions and grooves form in the chewing surfaces of the enamel.
