Majolica tiled spires in Sicily. Shape, structure and problems
2014
From the Classical era, the architecture of the Mediterranean were characterized by strong polychrome obtained with various decorative forms by elements of poor workmanship in the building smaller. This decorative forms were more ornate on the monumental architecture; among these the tiles are very present in the border regions. According to the architecture of the Islamic world and the local building culture, the tiles were reworked from surface decorations in brick and shingle, to less frequent three-dimensional elements that can be found in large numbers in the Sicilian area. The spires in majolica wedges, placed at the top of bell towers of urban centers Sicilian, represent striking arc…
The Effect of Age, Gender, and Insertion Site on Marginal Bone Loss around Endosseous Implants: Results from a 3-Year Trial with Premium Implant Syst…
2014
Objectives.The goal of this study was to evaluate bone changes around endosseous implants in partially edentulous patients.Materials and Methods.A total of 632 two-stage implants were placed in 252 patients. The implants had straight emergence profile, ZirTi surface, 3.3 to 5 mm diameter, and 8.5 to 13 mm length. Bone levels were assessed on orthopantomography immediately after surgery and after 36 months and marginal bone loss (MBL) was calculated from their difference.Results.Cumulative survival rate was 98.73%. Overall MBL was 0.8 mm ± 0.03 (mean ± SEM). Higher MBL was observed around implants in the maxilla than in the mandible (P<0.007). A relation between implant diameter and MBL (…
Living on the edge: assessing the extinction risk of critically endangered Bonelli’s eagle in Italy
2012
Background: The population of Bonelli’s eagle (Aquila fasciata) has declined drastically throughout its European range due to habitat degradation and unnatural elevated mortality. There are less than 1500 breeding pairs accounted for in Europe, and the species is currently catalogued as Critically Endangered in Italy, where the 22 territories of Sicily, represent nearly 95% of the entire Italian population. However, despite national and European conservation concerns, the species currently lacks a specific conservation plan, and no previous attempts to estimate the risk of extinction have been made. Methodology/Principal Findings: We incorporated the most updated demographic information ava…
Functional Rehabilitation of Mandibular Continuity Defects Using Autologous Bone and Dental Implants – Prognostic Value of Bone Origin, Radiation The…
2008
<i>Aim:</i> The aim of this retrospective study was to investigate prognostic parameters for the rehabilitation of mandibular continuity defects with free autologous bone and dental implants for patients after intraoral squamous cell carcinoma. <i>Methods:</i> Following potential prognostic factors for implant survival were analyzed: bony bed (local bone versus augmented iliac crest bone), radiation dose (no radiation, <50 Gy, ≥50 Gy) and implant dimensions. Kaplan-Meier survival estimates of the inserted implants were performed. <i>Results:</i> After 5 years, the cumulative survival rate of all investigated implants was 82.6%. Dental implantation into…

Background and objectives: To compare the medium- to long-term mechanical behavior of overdentures with two different retention systems: overdentures with Locator®
Comparative Analysis of Peri-Implant Bone Loss in Extra-Short, Short, and Conventional Implants. A 3-Year Retrospective Study
2020
Objective: To evaluate the influence of implant length on marginal bone loss, comparing implants of 4 mm, 6 mm, and >
Dystrophic epidermolysis bullosa: oral findings and problems.
2006
Dystrophic epidermolysis bullosa (DEB) is one of the three major types of epidermolysis bullosa (EB), an inherited cutaneous disease with blister formation following minor trauma. A subtype of DEB is recessive dystrophic epidermolysis bullosa, Hallopeau-Siemens type (RDEB-HS), where marked scarring leads to deformities of extremities. In RDEB-HS the mucous membranes may also be involved and form adhesions with ankyloglossia and microstomia. Oral hygiene is difficult. A 7-year-old boy with RDEB-HS was brought to the Johannes Gutenberg University dental clinic with dental pain. He had multiple carious lesions, poor oral hygiene and gingivitis. Because he was noncompliant and had microstomia, …
Platform switch versus platform match in the posterior mandible – 1-year results of a multicentre randomized clinical trial.
2014
Objective The purpose of this ongoing randomized study was to assess differences in bone level changes and success rates using implants supporting single crowns in the posterior mandible either with platform matched or platform switched abutments. Material and Methods Patients aged 18 and above, missing at least two teeth in the posterior mandible and with a natural tooth mesial to the most proximal implant site were enrolled. Randomization followed implant placement. Definitive restorations were placed after a minimum transgingival healing period of 8 weeks. Changes in crestal bone level from surgery and loading (baseline) to 12-month post-loading were radiographically measured. Implant su…
Dietary Habits in a Child Population in Relation to Caries Experience
2008
Sugar consumption in Spain has remained constant at around 80 g/day since the 1970s. Although intake as sugar has fallen considerably, to around 13.5 g/person/day, the intake in processed foods has risen. Meanwhile, caries prevalence is falling or stabilizing. This situation is common in developed countries, where the impact of diet on caries has altered, probably through greater use of fluoridated products. In the Valencia region, children habitually eat sugary foods and drinks and snacks that contain starches or sugars and starches. The present study analyzed the association between caries experience, quantified as the sum of the dfs and DMFS indices, and the consumption of cariogenic foo…
Oral and dental health of non-institutionalized elderly people in Spain.
2011
With aging of the populations, the oral health and hygiene of elderly people has become an important public health issue. In this cross-sectional study we investigated the prevalence of tooth decay and other periodontal diseases in a representative cohort of 480 non-institutionalized adults ≥65 years from the province of Valencia, Spain. Using a World Health Organization standard for an adult oral survey methodology, we obtained data on remnant teeth with the decayed, missing and filled teeth (DMFT) index, a Community Periodontal Index of Treatment Needs (CPTIN), attachment loss, and temporo-mandibular articulation (TMA) status. The prevalence of these conditions were compared by age and ge…
