The use of lasers in treating periodontal disease has been seen by some dental professionals as controversial. [6] The American Academy of Periodontology stated in 1999 that it was "not aware of any randomized blinded controlled longitudinal clinical trials, cohort or longitudinal studies, or case-controlled studies indicating that 'laser excisional new attachment procedure (or Laser ENAP)' or ...
In restorative dentistry, precision attachments are the functional mechanical parts of the removable partial denture made of plastic, metal or a combination of both. [1] They consist of two parts referred as the 'male' part that is fixed to a crown inside the patient's mouth and a 'female' part which holds the partial denture.
Consequently, substantial amounts of attachment may have to be sacrificed when crown lengthening is accomplished with an apically positioned flap technique. Importantly, for esthetic reasons, symmetry of tooth length must be maintained between the right and left sides of the dental arch.
1: Total loss of attachment (clinical attachment loss, CAL) is the sum of 2: Gingival recession, and 3: Probing depth. Gingival recession, also known as gum recession and receding gums, is the exposure in the roots of the teeth caused by a loss of gum tissue and/or retraction of the gingival margin from the crown of the teeth.

The lamina dura surrounds the tooth socket and provides the attachment surface with which the Sharpey's fibers of the periodontal ligament perforate. On an x-ray , a lamina dura will appear as a radiopaque line surrounding the tooth root .
A three unit porcelain fused to metal bridge (PFM) made by a dental technician A semi-precision attachment between teeth #3 and #4, with the mortise on #4. Note the lingual buttons extending, in the photo, upward on #2 (on the left) and downward on #4.
Dental abscesses can cause resorption of bone and consequent loss of attachment. Depending on the type of abscess, this loss of attachment may be restored once the abscess is treated, or it may be permanent. Many other conditions can cause permanent or temporary loss of attachment and increased tooth mobility.
The PDL is a part of the periodontium that provides for the attachment of the teeth to the surrounding alveolar bone by way of the cementum. The PDL appears as the periodontal space of 0.4 to 1.5 mm [ citation needed ] on radiographs, a radiolucent area between the radiopaque lamina dura of the alveolar bone proper and the radiopaque cementum.
