Peri-Implantational Loss clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Sensitivity and Specificity of Peri-Implantitis-Related Parameters

Start date: July 1, 2016
Phase: N/A
Study type: Observational

Bleeding on probing demonstrated to have high specificity with certain level of sensitivity to detect periodontal disease. Again, understanding the weak hemidesmosome attachment to the implant surface is imperative to discern on the probe penetration extent and subsequent bleeding. In the presence of inflammation, bleeding should be present indicating high sensitivity when probing deeper sites; nevertheless the lack thereof in healthy condition does not seem to translate high specificity. In this sense, it is noteworthy to mention that the mucogingival shift after implant placement often decreases the presence of keratinized mucosa, triggering a greater inflammatory condition on the peri-implant tissues. Thereupon, bleeding on probing, although might reliably indicate presence of disease, it does not seem to be a suitable diagnostic parameter. On the other side, suppuration characterizes the necrosis of peri-implant tissues, being rich in polymorphonuclear cells and as such, a sensitive indicator of bone turnover. In this sense, it must be noted that, if detected in early stages where bone resorption has not occurred yet, it might be a consequence of a foreign body reaction (i.e., residual cement or floss). Therefore, in the diagnosis of peri-implantitis, radiographic examination must be always incorporated to the clinical assessment as the 'gold standard'. Hence, the aim of this case-control study was to assess the diagnostic accuracy of peri-implantitis-related clinical parameters compared to otherwise healthy dental implants.
