Composition's effect of Origanum Syriacum essential oils in the antimicrobial activities for the treatment of denture stomatitis.

This research has several purposes: First to assess the bacterial and fungal minimum inhibitory concentration of Origanum Syriacum essential oil. Second to quantify its bactericidal and fungicidal minimal concentration against S. aureus, S.

Contribution of capsaicin-sensitive innervation to the continuous eruption of the rat mandibular incisors.

A major component of tooth innervation is made of capsaicin-sensitive primary afferents (CSPA). These fibers play a key role in tooth pain and inflammation; little is known, however, about the role of CSPA in tooth eruption. The aim of this study was to examine the role of the capsaicin-sensitive afferents in the process of eruption of intact rat incisors.

Modulation of incisor eruption in rats by sympathetic efferents.

Introduction: Intact neural supply is necessary for tooth eruption. Sympathetic denervation accelerates or decelerates the eruption rate depending on the tooth condition (intact or injured). The aim of this study is to reexamine the role of the sympathetic innervation, through the observation of the effects of pre or post ganglionic chemical sympathectomy on the eruption of intact rat incisors.

Fit of pressed crowns fabricated from two CAD-CAM wax pattern process plans: A comparative in vitro study.

Statement Of Problem: Subtractive and additive computer-aided design and computer-aided manufacturing (CAD-CAM) wax pattern processing are 2 methods of fabricating a pressed ceramic crown. Whether a subtractive milled wax pattern or a pattern from the micro-stereolithography additive process produces lithium disilicate crowns with better marginal and internal fit is unclear.

Materials And Methods: Ten silicone impressions were made for a prepared canine tooth.

Marginal and internal fit of pressed ceramic crowns made from conventional and computer-aided design and computer-aided manufacturing wax patterns: An in vitro comparison.

Statement Of Problem: To our knowledge, no studies have evaluated the influence of the wax fabrication technique on the internal adaptation and marginal accuracy of pressed ceramic single crowns.

Purpose: The purpose of this in vitro study was to compare the marginal and internal fit of a lithium disilicate crown fabricated either from conventional waxing or from a subtractive milled wax pattern.

Material And Methods: Ten silicone impressions were made for a maxillary canine prepared to receive a complete crown.

Considerations for Altering Preparation Designs of Porcelain Inlay/Onlay Restorations for Nonvital Teeth.

Purpose: The aim of this study was to compare all ceramic inlay/onlay survival rates in vital and nonvital teeth having the same cavity design. Filling the pulp chamber with ceramic materials or not was also discussed.

Materials And Methods: Ceramic class II inlays/onlays were made on 11 premolars and 30 molars: 14 vital, 27 endodontically treated.

Revisiting implant-retained mandibular overdentures: planning according to treatment needs.

Increasingly popular, implant-retained mandibular overdentures have a highly predictable success rate and provide many options in terms of design and attachment systems. General dentists may have some difficulties in choosing the appropriate system. This paper provides a general overview of the various options that are available, taking into consideration the specifications and challenges of each.

Prosthetic requirements for immediate implant loading: a review.

Purpose: The aim of this article is to review the current literature with regard to prosthetic considerations and their influence on the outcome of immediately loaded implants.

Materials And Methods: A broad search of the published literature was performed using MEDLINE and PubMed to identify pertinent articles.

Results: One hundred fifty six references were selected.

Oromandibular dystonia treatment following a loss of vertical dimension.

Unlabelled: Oromandibular dystonia is a rare condition of hyperkinetic motor dysfunction in the orofacial area. It is a centrally mediated disorder of unknown aetiology and manifested by a sustained contraction of masticatory muscles, involving one or both lateral pterygoids, and pushing the mandible forward. The prognosis is poor and the treatment is symptomatic.

Impression materials in fixed prosthodontics: influence of choice on clinical procedure.

The purpose of this article is to review impression materials used for fabricating fixed restorations in dentistry. Their compositions, properties, advantages, and disadvantages are presented and compared. How these properties influence clinical decisions is also described.

Inflammatory mediators released following application of irritants on the rat injured incisors. The effect of treatment with anti-inflammatory drugs.

The exchange of fluids and chemicals between the tooth pulp and the periphery, through the dentinal tubules has been well documented. Application of irritants on the open tubules produces aversion in awake rats that can be prevented by prior occlusion of these tubules. This study aims at characterizing the secretion of inflammatory mediators in tooth perfusates and assessing the effects of systemic pretreatment with anti-inflammatory drugs on the levels of these mediators.

Occlusion of dentinal tubules and selective block of pulp innervation prevent the nociceptive behaviour induced in rats by intradental application of irritants.

Objectives: Application of irritants on the exposed dentine of the incisors has been shown to produce aversive behaviour in awake rats. This study aims to demonstrate that the observed aversion is due to the infiltration of irritants through the dentinal tubules and the activation of capsaicin sensitive fibres in the tooth pulp.

Methods: Different groups of rats were subjected, under anaesthesia, to cutting of the distal 2 mm of their lower incisors and the fixation of an artificial crown that allows the application of 10-15 microl of solution.
