Gum grafting, also known as a gingival graft or periodontal plastic surgery, is a surgical procedure to reverse gum recession. Gum recession exposes the roots of teeth, [9] which can lead to sensitivity and put teeth at a higher risk of damage or disease [10] due to the loosening of their attachment within the gums and bones of the jaw.
The false positive rate is equal to the significance level. The specificity of the test is equal to 1 minus the false positive rate. In statistical hypothesis testing, this fraction is given the Greek letter α, and 1 − α is defined as the specificity of the test. Increasing the specificity of the test lowers the probability of type I errors ...
A free gingival graft is a type of gingival grafting performed to correct acquired deficiencies of the gum tissue around teeth or dental implants. Besides autologous tissues, xenogeneic collagen matrices are using for gingival augmentation after dental implantation. [ 1 ]
Failure to accomplish these methods prior restorations can lead to the complexity or risk of failure of treatment such as impression making, tooth preparation and restoration. Periodontal therapy should follow restorative method as the resolution of gingival inflammation may result in the repositioning of teeth or in soft tissue and mucosal ...
Failure rate is the frequency with which any system or component fails, expressed in failures per unit of time. It thus depends on the system conditions, time interval, and total number of systems under study. [1]
The rate of loss of attachment and bone loss is rapid. [19] Loss of attachment refers to the destruction of periodontium whereas the bone refers to the alveolar bone supporting the teeth. [23] The loss can be determined by using a calibrated periodontal probe and taking radiographs of the dentition. [24]
According to a 2012 review article by Demarco et al. covering 34 relevant clinical studies, "90% of the studies indicated that annual failure rates between 1% and 3% can be achieved with Class I and II posterior [rear tooth] composite restorations depending on the definition of failure, and on several factors such as tooth type and location ...
In statistics, when performing multiple comparisons, a false positive ratio (also known as fall-out or false alarm rate [1]) is the probability of falsely rejecting the null hypothesis for a particular test. The false positive rate is calculated as the ratio between the number of negative events wrongly categorized as positive (false positives ...
