Review
OBJECTIVES
A narrative review on the NO properties and their relationship with the oral environment describing NO's molecular origin, role, and perspectives regarding oral pathological, physiological, and regenerative processes for future applications and possible use as prevention or treatment in dentistry.
MATERIALS AND METHODS
Pubmed was searched using the word "nitric oxide." Reviews, clinical studies, and experimental studies were eligible for the screening process. Similar search procedures were then performed with the additional search words "conservative dentistry," "orthodontics," "endodontics," "implants," "periodontics," "oral cancer," "pulp revascularization," and "oral surgery." Furthermore, references of included articles were examined to identify further relevant articles.
RESULTS
There is a relationship between NO production and oral diseases such as caries, periodontal diseases, pulp inflammation, apical periodontitis, oral cancer, with implants, and orthodontics. Studies on this relationship and uses of NO, in diagnosis, prevention, and treatment, are being developed. Also, some NO and oral cavity patents have already registered.
CONCLUSIONS
The understanding of how NO can interfere in oral health maintenance or disease processes can contribute to elucidate the disease development and optimize treatment approaches.
CLINICAL RELEVANCE
NO has considerable biotechnological potential and can contribute to improving diagnostics and treating the oral environment. As a biomarker, NO has an important role in the early diagnosis of diseases. Regarding treatments, NO can possibly be used as a regulator of inflammation, anti-biofilm action, replacing antibiotics, inducing apoptosis of cancerous cells, and contributing to the angiogenesis. All these studies are initial considerations regarding the relationship between NO and dentistry.

Review
Dental impressions are used to produce a replica of an oral structure for use as a permanent record or in the production of a dental restoration or prosthesis. Accurate impression-taking is an essential procedure in implant dentistry. Traditionally, clinicians have used two different implant impression techniques: transfer and pick-up. The pick-up impression technique is considered to be the more accurate of the two because with this technique the impression copings are maintained within the impression upon removal from the mouth, thus eliminating the potential for error that may occur when manually placing the copings in the impression as in the transfer technique. This design has become increasingly popular and useful for multi-unit impressions. The purpose of this article is to review various pick-up impression copings and propose a new impression coping design for accurate, easy impression-taking without discrepancies.

STATEMENT OF PROBLEM
Marginal fit of zirconia restorations is an important criterion for their long-term success. However, in spite of the wide use of zirconia in dentistry, the relationship between marginal fit and low-temperature degradation from aging is unclear.
PURPOSE
The purpose of this in vitro study was to compare the marginal adaptation of veneered and monolithic zirconia and metal-ceramic computer-aided design and computer-aided manufacturing (CAD-CAM) crowns before and after cementation and to evaluate the influence of artificial aging on the adaptation of zirconia crowns.
MATERIAL AND METHODS
Seventy-two standardized dies were prepared to receive a posterior crown and randomly divided into 6 groups (n=12) as per the material and the presence or not of cement: metal-ceramic, veneered zirconia, and monolithic zirconia. The zirconia groups were subjected to accelerated low-temperature degradation through hydrothermal aging in an autoclave at 131 °C and 0.17 MPa for 5 and 20 hours. A scanning electron microscope with a magnification of ×1000 was used for marginal adaptation measurements, and X-ray diffraction (XRD) was used to characterize phase transformation degradation. The data were statistically analyzed using 2-way ANOVA, repeated measures ANOVA with Greenhouse-Geisser correction, and the t test (α=.05).
RESULTS
No significant differences in the marginal discrepancy were recorded among the analyzed groups. The presence of cement did not influence marginal fit in any treatment group. No significant differences were observed in the marginal adaptation values before and after aging (P>.05). After 20 hours of aging, the monoclinic phase increase to 8.3% on veneered zirconia and to 3.1% on monolithic crowns.
CONCLUSIONS
Monolithic and bilayer CAD-CAM zirconia crowns showed marginal gaps that were within an acceptable range of clinical discrepancy, regardless of cementation. Marginal adaptation was not influenced by aging. Low-temperature degradation did not lead to a significant transformation from the tetragonal to monoclinic phase.

STATEMENT OF PROBLEM
New computer-aided design and computer-aided manufacturing (CAD-CAM) lithium disilicate glass-ceramics have been marketed. However, information concerning their biomechanical behavior is lacking.
PURPOSE
The purpose of this in vitro study was to compare the fit and fatigue behavior of two recently introduced CAD-CAM lithium disilicate materials with the standard IPS e.max CAD ceramic and to investigate the effect of the thermal treatment for crystallization on crown fit.
MATERIAL AND METHODS
Monolithic crowns (n=15) were milled from 3 CAD-CAM lithium disilicates: IPS e.max CAD (Ivoclar AG), Rosetta SM (Hass), and T-lithium (Shenzhen Upcera Dental Technology). Marginal and internal fit were evaluated using the replica technique before and after crystallization, and the fatigue behavior of the luted crowns was evaluated by the step-stress method. One-way ANOVA and the Tukey test were used to compare fit among the materials. Fatigue failure load was evaluated by the Kaplan-Meier and Mantel-Cox tests. The effect of crystallization on fit was evaluated with the paired t test (α=.05).
RESULTS
Marginal fit was different between IPS e.max CAD (74 μm) and Rosetta SM (63 μm) (P=.02). T-lithium was similar to the other ceramics (68 μm) (P>.05). Occlusal internal space was similar among all materials (P=.69). Fatigue failure loads of Rosetta SM (1160 N) and T-lithium (1063 N) were similar to IPS e.max CAD (1082 N) (P>.05). The fatigue failure load of Rosetta SM was higher than that of T-lithium (P=.04). Crystallization reduced the axial internal space of all materials (P<.05) without significantly affecting marginal fit (P>.05).
CONCLUSIONS
The fit and fatigue behavior of Rosetta SM and T-lithium were similar to that of IPS e.max CAD. Crystallization reduced the internal space of the crowns.

Review
AIMS
This work discusses the procedures and outcomes of restorative and endodontic treatments performed under general anesthesia, with examples from the Unit of Special Care Dentistry at the University Hospital of Clermont-Ferrand.
METHODS AND RESULTS
The restorative and endodontic treatment techniques used in the Special Care Unit are described. These techniques are compared to existing reports in the literature of treatment procedures under general anesthesia. Little evidence was found in the literature regarding sealants or restorative protocols. A few studies described root canal treatment and pulpotomy protocols carried out under general anesthesia, and the results of these met academic outcome standards.
CONCLUSION
Patients with equal needs should have equal access, equal quality of treatment and equal treatment outcomes, regardless of whether a facilitatory procedure is used to achieve treatment. The provision of restorative treatment under general anesthesia is essential to avoid an excessive number of extractions in patients unable to receive treatment in the chair. Restorative care provided under general anesthesia should be standardized and evaluated in the same way as treatment performed under local anesthesia. In this way, the provision of conservative dental care under general anesthesia could be promoted and the maintenance of a functional dentition encouraged.
