However, important ethical issues encompass treatment for purely esthetic reasons. Also, perceptions of what is esthetic differ among patients and clinicians. Therefore, the aim of this article is to make suggestions regarding some of the issues surrounding the ethical, esthetic treatment of patients, as well as present three cases illustrating the different meanings of esthetic health to different people.

The first groups of 15 teeth were kept for 1 day, the second for 1 week, the third for 4 months, the fourth for 6 months and the fifth for 12 months at 37 °C (80% relative humidity). The teeth were immersed in Indian ink for 90 h, split and sectioned longitudinally. The extent of leakage was measured under magnification (6×).

Methods: Fifty maxillary sound premolars were evaluated applying axial forces (range 98-294N) on their occlusal surface by the use of a mechanically controlled loading device inducing cuspal deflection while sophisticated Laser LTS twin sensor registered their cuspal movement. Cusp deflection values in micron were recorded for each tooth sequentially in intact condition and after conclusion of endodontic and restorative procedures (MOD cavity. Teeth were randomly divided in 10 groups (n =5) and restored with ten different materials as reported on Tab. 1. For all ten groups were evaluated: a) amount of cusps deflection; b) average stiffness; c) percentage structural recovery, in both intact and restored state. Results: Average stiffness in intact and restored status and percentage of structural recovery have been calculated for all experimental groups respectively. Results are reported on table below. Conclusions: Bonded composite restorations in endodontically treated teeth could be an appropriate way to afford good resistance to occlusal loads. It is important to highlight how the use of fibber glass posts and micro-hybrid composite materials in such restorations came out to be a suitable solution for structural recovery of the treated element. Concluding, direct composite techniques could guarantee an adequate aesthetic and structural recovery of endodontically treated elements.

Methods:A mechanically controlled loading device induced cuspal deflection by axial force (range 98-294 N) on an occlusal surface while sophisticated Laser LTS twin sensor registered the amount of deflection. Cusp deflection values in micron, were recorded for each tooth (Cerutti et al., IADR-Washington 2000, Goteborg 2003, Am. J. Dent 2004). Fifteen maxillary sound premolars teeth were sequentially evaluated in the following conditions: a) intact tooth; b) completion of restorative (cavity MOD preparation: depth 4mm. and width of a half of intercuspidal distance) and endodontic procedures; c) after cyclic fatigue test in a 50% AgNO3 solution, at a frequency of 2 Htz. for five ...

Methods: for the shear bond strength (SBS) testing, thirty molars were ground with 400-grit SiC paper to expose the dentin surface and assigned randomly to 6 groups (n=5). The provisional cement (TempBond, Kerr) was applied in 5 groups and scaled off with a curette after 24h at 37°C; 1 group was maintained as a control (freshly prepared dentin, not contaminated with provisional cement). The cleaning procedures considered were: no further treatment after scaling (NO_T), air abrasion treatment using 50 micron aluminum oxide (AlO), Air Flow treatment using NaHCO3 powder (Airflow), Prophylaxis Paste treatment (P_P), 10% sodium hypochlorite gel conditioning (AD Gel, Kuraray) after dentin etching (ADGel). In all samples, dentin surface was etched for 20s with 35% orthophosphoric acid (3M); all groups were treated by a bonding agent (Scotchbond Multipurpose Adhesive, 3M). A 4mm metal ring in diameter was used to set the dual-curing composite resin cement (DuoCement, Colténe). Specimens were stored at 37°C for 24h, prior to SBS tests that were performed using an Instron at a cross head speed of 1mm/min. Means and standard deviations were compiled and values (expressed in MPa) were analyzed by ANOVA. Results:

Methods: Sixty freshly non carious human molars were grounded to expose middle dentin, which was polished to 600-grit. Half of the samples was prepared with an Nd:YAG laser for 20 seconds at 10Hz and 80mJ (LASER); the other half was maintained as a control (CONTROL). Three dentin adhesive systems were applied, according to manufacturer's instructions, to the laser irradiated surfaces and to the control surfaces: Scotch Bond Multi-Purpose -3M ESPE (SBM); Scotch Bond 1 -3M ESPE (SB1); Adper Prompt L-Pop -3M ESPE (LP). For SBM and SB1 groups dentin surface was etched with 35% phosphoric acid gel for 15s. A 5mm metal ring was used to set the resin composite (Z100, 3M ESPE) and specimens were stored in water at 37% for 24h. Shear Bond Strength (SBS) was conducted by means of a universal testing machine with a cross head speed of 1mm/min. The results were statistica...

Methods: One hundred disc-shaped specimens (6 mm in diameter, 2 mm in thickness) were made using five different dental restorative composite materials (Filtek Silorane and Filtek SupremeXT, 3M ESPE; CeramX Duo, Dentsply; Venus, Heraeus; Tetric EvoCeram, Ivoclar Vivadent). The samples were light cured with a halogen lamp (1000 mW/cm2 ) for 40 seconds in oxygen-free conditions below a glass slide device to prevent roughness, then sterilized by means of a UV-lamp. Specimens for each material were divided in 5 groups, then incubated for 2, 4, 6, 24 and 48 h at 37 C with Streptococcus mutans NCTC 10449 and processed to extract DNA from the bacteria adhered to the surfaces. Real-time PCR amplification was performed. Using a standard quantitative curve b...

Aim of this paper is to evaluate, by a clinical longitudinal study, the type of sealing and the outcome of endodontic treatment, performed by new Profile and Thermafil technique, in teeth with or without periapical lesions. A total of 122 teeth in 64 patients were consecutively enrolled in the study; 63 teeth had normal periapical status (Group A) and 59 teeth had periapical lesion (Group B). Endodontic therapy was carried out by Profile .04 and Profile .06 NiTi engine driven files and the obturation was made by Thermafil, a filling technique based on heated gutta-percha surrounding a plastic carrier. The type of sealing was evaluated by a score (A best - D worst) and the type of healing was classified as complete, incomplete and failure according to previous published data. The radiographical outcome of the teeth was evaluated by indep...

The changes affect the chemical, physical and elastic properties of the dentin, the resistance to fatigue, the morphology and bio-mechanical behavior. Nevertheless survival of a tooth endodontically treated is influenced so much greater the quantity and quality of remaining tooth structure. The removal of decayed tissue and tooth preparation for endodontic treatment are therefore the first factors which weaken the structure of the tooth. The tooth endodontically treated may require complex strategies of restoration and a vision of multidisciplinary treatment. There are situations for which the choice to insert a fiber post is crucial to support ...

In order to be part of the study, every patient was to need at least 2 restorations on vital teeth, which had to be located on opposite quadrants of the oral cavity. All the restorations were made with micro-layering technique using Swiss Master Light (EMS) curing light (800 mW/cm 2 for 20s). The test groups were randomly assigned to the class V cavities using composite and adhesive materials as follows: A)testing material -Venus-Diamond and GlumaComfortBond (Heraeus) B)competitor -CeramX-Duo and Prime&Bond-NT (Dentsply) A quadrant-based randomization was used to assign to every restoration its filling material and adhesive system: restorations have been performed according to the adhesive dentistry techniques by one expert clinician (>10 years of clinical experience). Each restoration was polished with the 2-step polishing system provided by Heraeus Kulzer (pre-polisher and high-gloss finisher...

Methods: Intact and restored molars and premolars were digitized with a micro-CT scanner. Surface contours of the dental structures were meshed and imported in a FE software package to create 3D solid models. 12 models of endodontically-treated molars and premolars with different preparations for resin-composite indirect restorations (Class II mesial-occlusal, MO and mesial-occlusal-distal, MOD; overlay) and different thickness of luting agents were submitted to occlusal load. Von Mises equivalent stresses (Mpa) were evaluated for all the proposed models. Models of sound teeth were used as controls. Results: The maximum values of stresses were always reached in the zones of application of the load and accordingly in the enamel, except in the cases of overlay where such zones belonged t...
