[The effect of instrumentation on original apical foramen shape using steel vs niti rotatory: computerized analysis]

2002

BACKGROUND. A fundamental requirement to obtain a correct endodontic preparation depends on the respect, during cleaning and shaping, of the original morphology of the apical foramen, (AF), so that the filling material will form a complete seal. METHODS. In our previous studies, in order to verify if this presumption was respected using rotary NiTi instruments with cutting tip, we instrumented extracted teeth characterised by a different degree of root curvatures. Using a standardized system to replace the sample, the original shape of the apical foramen of each tooth was recorded using a computerised technique and then compared to the shape after instrumentation. The data showed difference…

A combined treatment regimen for chronic desquamative gingivitis in patients with oral lichen planus

2007

Background: Chronic desquamative gingivitis (DG) is a condition characterized by erythema, ulceration, and desquamation of the free and attached gingiva, usually expression of a district-systemic disease, such as oral lichen planus (OLP). Methods: A combined protocol of oral hygiene and topic corticosteroid therapy was applied in 30 patients with DG associated with OLP. Plaque index (PI) and bleeding on probing (BoP) were evaluated at baseline and after 3 months. Results: PI scoring was significantly lower after treatment in anterior, posterior, and all sites (P < 0.0001) as well as in vestibular and lingual ones (P < 0.0001 and P = 0.0001, respectively). BoP measures were found to be reduc…
