Intrapulpal temperature changes during root surface irradiation with an 809-nm GaAlAs laser

2002

The aim of this study was to explore, in vitro, whether the irradiation of human root surfaces with a diode laser might induce nonphysiologic intrapulpal temperature elevations and, therefore, jeopardize pulp vitality.The pulps were removed from human maxillary and mandibular incisors extracted for periodontal reasons. The root canals were enlarged to an apical size #60 file. The teeth were radiographed with standard dental films and a millimeter grid to determine root thickness. The thickness of dentin between the root surface and the pulp in the irradiation areas was 1, 2, and 3 mm. To determine intrapulpal temperature changes during laser irradiation, 0.5-mm K-type thermocouples were ins…

SISTEMI VERDI COME CULTURA RIGENERATIVA: STRUMENTI E TECNOLOGIE

2021

The study analyzes and proposes in the historical and in the area immediately to it adjacent, the "values-nature" of the buildings through the creation of gardens wall and vertical gardens in the elevatiloy of non-monumental buildings. The study deepens in particular the specificity of the garden roof and the garden vertical, recognizing benefits and critical issues that distinguish these green systems for construction. It also deepens the concept of resilience in close relationship sustainability and regenerative design applied to the built environment. The theme of regenerative design is studied and promoted as an adaptive strategy at the design stage; it requires you to leave nature stre…

Lo studio analizza e propone nel centro storico e nell’area immediatamente ad esso adiacente la ”valori-naturazione” degli edifici attraverso la creazione di giardini pensili e di giardini verticali nei prospetti degli immobili non monumentali. Lo studio approfondisce in particolare le specificità del tetto giardino e del giardino verticale riconoscendo benefici e criticità che contraddistinguono questi sistemi verdi per l’edilizia. Si approfondisce inoltre il concetto di resilienza in stretta relazione alla sostenibilità e al regenerative design applicato all’ambiente costruito. Il tema del regenerative design viene studiato e promosso come strategia adattiva in fase di progettazioneesso richiede di lasciare che la natura rafforzi le sue capacità di autoguarigione e la sua integrità mediante l’uso di metodologie rigenerative integrate. Lo studio intende proporre una base su cui poter fondare ulteriori sviluppi scientifici sui sistemi di inverdimento esistenti o su brevetti in fase di sviluppo applicabili ai centri storici del territorio siciliano. Si prevede la redazione di un libretto divulgativo per gli abitanti volto alla disseminazione di una cultura del verde tecnologico ancora poco presente nei centri siciliani. Per quanto concerne le modalità attuative del progetto di ricerca sono state individuate: sia azioni orientate alla sensibilizzazione dei cittadini di Alcamo e dei residenti nella provincia sia l’individuazione di possibili forme di incentivazione per la mobilitazione di risorse private. Tale studio si inserisce nell’ambito di un filone di ricerca in itinere sui sistemi tecnologici di inverdimento per la costruzione di “Città parco” e di “Green hill” le cui linee guida e modalità attuative sono già state individuate dall’autrice per diversi comuni siciliani.Settore ICAR/12 - Tecnologia Dell'Architettura

Healing of intrabony defects following treatment with a bovine-derived xenograft and collagen membrane

2003

Objectif: L'objectif de cette etude etait de comparer cliniquement le traitement de lesions intra-osseuses profondes avec xenogreffe d'origine bovine (BDX) associe a une membrane collagene bioresorbable pour acceder a la chirurgie a lambeau. Methode: Vingt-huit malades souffrant de parodontite chronique, chacun montrant une lesion intra-osseuse ont ete traites au hasard au BDX+membrane collagene (essai) ou avec chirurgie a lambeau (controle). Les mesures des tissus mous ont ete prises au depart et 1 an apres la therapie. Resultats: Aucune difference dans aucun des parametres etudies n'a ete observee au depart entre les deux groupes. La cicatrisation a ete sans incident pour tous les malades…

Management of shortened dental arches and periodontal health: 5-year results of a randomised trial

2014

Summary In a multicentre randomised trial (German Research Association, grants DFG WA 831/2-1 to 2-6, WO 677/2-1.1 to 2-2.1.; controlled-trials.com ISRCTN97265367), patients with complete molar loss in one jaw received either a partial removable dental prosthesis (PRDP) with precision attachments or treatment according to the SDA concept aiming at pre-molar occlusion. The objective of this current analysis was to evaluate the influence of different treatments on periodontal health. Linear mixed regression models were fitted to quantify the differences between the treatment groups. The assessment at 5 years encompassed 59 patients (PRDP group) and 46 patients (SDA group). For the distal meas…

Periodontal, salivary and IL-6 status in rheumatoid arthritis patients. A cross-sectional study

2017

Background: The aim of this study was to determine whether saliva interleukin-6 (IL-6) levels are elevated in patients with rheumatoid arthritis versus a control group and examine the possible relationship between the oral condition and the risk of RA. Material and Methods: In 30 patients with RA and 30 healthy controls, different periodontal indices were recorded; sialometric measurements were taken to determine resting whole saliva, stimulated whole saliva and stimulated parotid saliva flow; and the saliva IL-6 levels were measured. Logistic regression analysis was performed, with the presence or absence of RA as dependent variable. Results: The patients with RA had a greater presence of …

Efficacy of Subgingival Irrigation Using Herbal Extracts on Gingival Inflammation

2003

The aim of the present study was to investigate the efficacy of an herbal-based mouthrinse in combination with an oral irrigator in reducing gingival inflammation.A total of 89 patients (45 females, 44 males; mean age 49.1 +/- 1.31 years) were included in this prospective, randomized, double-blind clinical study and allocated to 3 treatment groups: group 1 (n = 34), treated with an oral irrigator with subgingival tips and an herbal-based mouthrinse; group 2 (n = 29), the oral irrigator was applied in combination with a conventional mouthwash; and group 3 (n = 26), treated with the conventional mouthwash without subgingival irrigation. Data collected at baseline and after 4, 8, and 12 weeks …

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…

Periodontal Treatment with an Er:YAG Laser or Scaling and Root Planing. A 2-Year Follow-Up Split-Mouth Study

2003

Non-surgical periodontal treatment with an Er:YAG laser has been shown to result in significant clinical attachment level gain; however, clinical results have not been established on a long-term basis following Er:YAG laser treatment. Therefore, the aim of the present study was to present the 2-year results following non-surgical periodontal treatment with an Er:YAG laser or scaling and root planing.Twenty patients with moderate to advanced periodontal destruction were treated under local anesthesia, and the quadrants were randomly allocated in a split-mouth design to either 1) Er:YAG laser (ERL) using an energy level of 160 mJ/pulse and 10 Hz, or 2) scaling and root planing (SRP) using han…
