Longevity and risk factors of post restorations after up to 15 years: A practice-based study.
2020
Abstract Introduction The aims of this multicenter, practice-based cohort study were to evaluate the success and survival of endodontically treated teeth with post restorations (ETT+Ps) and to analyze factors associated with the longevity of ETT+Ps. Methods Eight general dental practitioners each placed up to 27 ETT+Ps without any restriction to post materials or dimensions. Only incisors, canines, and premolars were included. At the last follow-up visit, ETT+Ps were considered as successful if the post and the initially placed definitive restoration were sufficient, whereas ETT+Ps were considered as survived if the post was still in function. Multilevel Cox proportional hazards models were…
Papilla and pontic area regeneration in patient with gingival smile: A clinical case
2018
Purpose Connective tissue grafts are widely documented as a predictable technique for treating Miller Class I and II recessions, as well as procedures in which soft tissue augmentation is required for aesthetic reasons. This article aims to explore the resolution of a clinical case with this type of problema. Clinical case This case describes a technique for reconstructing a pontic area and adjacent papilla by means of two consecutive connective tissue grafts. The first graft served to increase the amount of tissue in the horizontal direction, and the second promoted vertical reconstruction of the defect. Results and conclusion In cases with aesthetic requirements, restorative intervention …
In assenza di intervento. Rappresentazioni digitali di restauri virtuali
2015
La simulazione della realtà attraverso le tecniche di rappresentazione digitale viene oggi in aiuto dei restauratori poiché consente loro di verificare l’impatto di un restauro ancor prima di intervenire. Ciò può contribuire a evitare interventi troppo invasivi e a contenere errate pratiche che, a volte, irrimediabilmente cancellano le tracce originali. Il saggio analizza alcune esperienze di ricerca sull’illuminazione nei modelli virtuali che sono emblematiche di un approccio possibile. Le ricostruzioni tridimensionali digitali analizzate forniscono non solo le informazioni spaziali e dimensionali ma anche gli aspetti cromatici e le caratteristiche di illuminazione di un’architettura. Lo s…
Augstā purva biotopu atjaunošana īpaši aizsargājamās dabas teritorijās Latvijā 2010-2013
2013
Purvs ir viena no jutīgākajām dabas ekosistēmām. Projekta mērķis ir atjaunot augstā purva biotopus četru dabas liegumu – Melnā ezera purva, Aklā purva, Rožu purva, Aizkraukles purvu un mežu – degradētajās platībās un pievērst sabiedrības uzmanību Latvijas dabas vērtībām.
Augstā purva biotopu atjaunošana īpaši aizsargājamās dabas teritorijās Latvijā
2010
Purvs ir mitra dzīvotne, kurai raksturīga aktīva kūdras veidošanās. Tā ir mājvieta daudziem augiem un dzīvniekiem, kuri nespēj dzīvot citur. Neskarti augstie purvi ir rets un apdraudēts biotops Eiropā. Nosusināšana, kūdras ieguve, mežu stādīšana un zemes rekultivācija pēdējās desmitgadēs ir nelabvēlīgi ietekmējusi purvus. Meliorācijas sistēmu ietekmes dēļ Aizkraukles purvā un mežos, Aklajā, Rožu un Melnā ezera purvā purva biotopi ir izmainījušies. Projekta mērķis ir atjaunot dabisko ūdens līmeni projekta vietās – augstā purva biotopos, kurus ir ietekmējusi nosusināšana – tādējādi aizsargāt Eiropas un Latvijas nozīmes purva biotopus, augus un dzīvniekus.

Microbiological characterization and effect of resin composites in cervical lesions
2017
Background Non carious cervical lesions associated to muscle hyperfunctions are increasing. Microhybrid resin composites are used to restore cervical abfractions. The purpose of this study was to investigate if resin composites modify tooth plaque, inducing an increment of cariogenic microflora and evaluate their effect, in vivo and in vitro, against S. mutans. Material and Methods Eight abfractions were restored with two microhybrid resin composites (Venus, Heraeus-Kulzer® and Esthet-X, Dentsply®), after gnatological therapy, in three patients with muscle hyperfunctions. For each abfraction three samples of plaque were taken from the cervical perimeter: before the restoration, one week and…
Re-establishment of zooplankton communities in temporary ponds after autumn flooding: Does restoration age matter?
2012
Abstract In temporary ponds, reestablishment of zooplankton communities depends on recruitment from the egg bank, the arrival of dispersers from within the region, and on successful establishment of newly arrived species following interaction with local abiotic and biotic factors. When the ponds dry up, zooplankton species may survive as dormant eggs, and since not all eggs hatch in the next season, eggs will accumulate in the sediment over time, representing an archive of the pond's historical biodiversity. To study the effect of “restoration age” (the time since a water body was restored), we studied groups of ponds that were restored in different years (1998, 2003 and 2007). The restorat…
Il progetto I-Access, intreccio di competenze ed esperienze
2021
Questo contributo descrive il progetto INTERREG Italia-Malta 1/16, di cui il Dipartimento di Architettura è stato beneficiario. La proposta, nell’ambito disciplinare del restauro, mira a creare un percorso di azione-apprendimento da applicare nei quartieri storici di Palermo e La Valletta attuando un metodo di lavoro integrato e totalmente interdisciplinare. Il progetto riguarda l’accessibilità fisica, con la progettazione di interventi architettonici, la fornitura di strumenti tecnologici e informatici di supporto per un trasferimento più agevole, e l’accessibilità culturale, che si esprime nella “rete” di comunicazione virtuale per aree non facilmente raggiungibili, e una parallela attivi…
The Use of Hall's Technique Preformed Metal Crown (HTPMC) by Pediatric Dentists in Malaysia
2021
Introduction. Hall’s technique preformed metal crown (HTPMC) has been used widely by pediatric dentists in developed countries as a new approach for managing decayed primary molars without local anesthesia, caries removal, and tooth preparation. Currently, inadequate information is available regarding the implementation of this technique (HTPMC) in Malaysia. This study is aimed at evaluating the implementation of HTPMC by Malaysia’s pediatric dentists and identify the co-occurrence frequencies of the HTPMC implementation with the respondents’ demographic profile. Materials and Methods. A cross-sectional questionnaire-based research was conducted among 65 pediatric dentists in Malaysia. Onli…
