1.) Measure the pipes. Starting at the water heater, measure lengths of insulation needed to cover all accessible hot water pipes, especially the first 3 feet of pipe from the water heater. It's also a good idea to insulate the cold-water inlet pipes for the first 3 feet.
B, which stands for buccal, is the surface of the tooth that faces the cheek. L, which stands for lingual, is the surface towards the tongue. Now, if the dentist says number 3MOD, you know you have a cavity on your upper right first molar and that it involves the front, top, and back parts of the tooth.eeth 24 and 25 are the lower front teeth (called the lower left and right central incisors). The code letter refers to different parts or surfaces of the tooth. For example, M stands for mesial (the front surface of the tooth). D stands for distal (the back surface).
Out of nowhere, he or she rattles off alpha-numeric jargon: 3MOD, 5DO, 13MFD and so on. The dentist is using a form of dental shorthand. Numbers represent teeth that have cavities or other problems. The upper right, third molar or wisdom tooth (this is the one farthest back in the mouth) is tooth number one. Tooth 16 is the upper left, third molar. Number 17 is the lower left, third molar. And 32 is the lower right, third molar.
