Reflex epilepsy and non-ketotic hyperglycemia.

Epileptic seizures are paroxysmal events, and it is likely that many, if not most, of them are precipitated by known or unknown factors acting on a central nervous system that is predisposed to the production of epileptic discharges by the presence of an organic lesion, a genetically determined neuronal hyperexcitability, or both. Known precipitating influences are quite varied. We report the case of a 58 years-old patient, followed for non-ketotic hyperglycemia, who presented with focal seizures exclusively induced by specific, active or passive, postures and movements of the right arm or hand.

Four different bonding systems, 3M ScotchBond Multipurpose (SB), Clearfil Liner Bond 2 (LB2), Opti Bond (OB), and Prime & Bond 2.1 (PB 2.

The effect of simulated intrapulpal pressure on bond strength to enamel and dentine.

The purpose of this study was to evaluate the effect of simulated intrapulpal pressure on the shear bond strength (SBS) of a self-etching bonding system (Clearfil Liner Bond II) to both enamel and dentine surfaces. Forty-two caries-free human molar teeth were randomly assigned to two equal groups (n=21). One group of 21 teeth was connected to a special pulpal pressure machine, which is developed to simulate in vivo conditions.

Comparison of antibacterial activity of two dentin bonding systems using agar well technique and tooth cavity model.

Objective: This study compared the antibacterial activities of two dentin bonding systems (ABF, Kuraray and Reactmer Bond, Shofu) by a conventional agar well technique and a newly designed in vitro test using tooth model.

Methods: In the agar well technique, the test materials were filled in the wells of Muller Hinton agar plates inoculated with Streptococcus mutans NCTC10449, and the diameters of inhibition zones produced around the materials were measured after 24h of incubation. For the tooth model test, three cavities (diameter 1mm, depth 2mm) were prepared in the flat occlusal dentin of human extracted molar.

Shear bond strengths of tooth fragments reattached or restored.

This study investigated the shear bond strengths of sectioned human mandibular incisor edge fragments reattached using luting cements, bonding agents or restored with composite resins. Seventy teeth were randomly distributed among six experimental groups and a control group. Leaving half of the anatomic crowns exposed, the teeth were embedded in self-cure acrylic resins with the exposed part then sectioned.

1.3 Development of professional competences.

Competency-based education, introduced approximately 10 years ago, has become the preferred method and generally the accepted norm for delivering and assessing the outcomes of undergraduate (European) or predoctoral (North America) dental education in many parts of the world. As a philosophical approach, the competency statements drive national agencies in external programme review and at the institutional level in the definition of curriculum development, student assessment and programme evaluation. It would be presumptuous of this group to prescribe competences for various parts of the world; the application of this approach on a global basis may define what is the absolute minimum knowledge base and behavioural standard expected of a 'dentist' in the health care setting, while respecting local limitations and values.

Bond strength of five current adhesives to caries-affected dentin.

Five current dentin adhesives were evaluated for their ability to bond to caries-affected dentin. The materials were: total etch [Solid Bond (SB)], two self-etch [Clearfil SE Bond (CSE), Etch and Prime (EP)], two one bottle [Prime and Bond 2.1 (PB), One Coat Bond (OCB)].

Risk factors determining allergic airway diseases in Turkish subjects.

With regard to changes in life-style after the 1980s, the reflection of environmental factors on the evolution of allergic airway disease (AAD) has not yet been analyzed in Turkey. In this trial, we aimed to determine the factors related to AAD in Turkish subjects. Patients diagnosed as having asthma and/or rhinitis with positive skin prick tests (SPTs) were accepted as members of the "atopic group" (n = 235).

Necrotizing sialometaplasia of parotid gland: a possible vasculitic cause.

Necrotizing sialometaplasia at the parotid gland location is rare and simulates malignant disease. If it is seen at this location, the causes may be previous dental or parotid gland surgical procedures, which result in blood vessel injuries and thrombosis. We report a parotid gland necrotizing sialometaplasia of a 17-year-old girl, possibly caused by primary vascular damage or vasculitis.

Clinical features and atopy profile in Turkish subjects with analgesic intolerance.

The factors underlying analgesic intolerance (AI), particularly the role of ethnic characteristics, are readily not clear. In this trial, we aimed to assess the predictive features of AI in Turkish subjects. One hundred and ninety patients with AI were enrolled into the study conducted in our tertiary care clinic.

Amalgam repair: evaluation of bond strength and microleakage.

This study evaluated the tensile bond strength of "repaired" amalgams and compared the degree of microleakage. Amalgam (Cavex avalloy) was condensed into plastic tubes (3 mm in diameter, 10 mm in height) to the half-length. After storage in water at 37 degrees C for two days, the remaining parts of tubes were filled with amalgam (A), cavity varnish (CV)+A, Liner Bond 2V (LB2V)+A, 3M Opal Luting Cement (3MOLC)+A, Panavia F(PF)+A, Metabond(MB)+A, Fuji BondLC(FB)+A, HytacOSB(HOSB)+Hytac Aplitip (H), Liner Bond2V+Clearfil AP-X(CAP).

Restoring function and esthetics in a patient with amelogenesis imperfecta: a case report.

Amelogenesis imperfecta is a hereditary disorder that affects enamel on primary and permanent teeth. It is a rare dental disease but represents a major restorative challenge for the dentist. A 14-year-old boy presented with sensitive, discolored, and mutilated teeth and a decreased vertical dimension of occlusion.

Bonding strength to two different surfaces of dentin under simulated pulpal pressure.

Purpose: The purpose of this in vitro study was to measure and compare the in vitro shear bond strengths (SBS) of the following dentin bonding systems to different dentin surfaces under simulated pulpal pressure: Liner Bond 2 (self-etching) (LB2), Liner Bond 2V (self-etching) (LB2V), Opti Bond Solo (single component) (OBS), Fuji Bond LC (filled) (FBLC), Prime & Bond 2-1 (single component) (P&B2-1), and Solid Bond (total etching) (SB).

Materials And Methods: Occlusal and buccal surfaces of 60 extracted human molars were prepared to expose the dentin bonding surface. After being wet ground with 600-grit abrasive papers, teeth were randomly assigned to 6 equal groups of 10 each.

Regional bond strengths of adhesive resins to pulp chamber dentin.

Microleakage of oral microorganisms, which can occur due to the lack of sealing ability of permanent restorative materials, may cause failure of root canal treatments. Although a great deal of research has been done on sealing enamel and coronal dentin with resins, little research has been done on the adhesion of resins to the walls of pulp chambers. The purpose of this study was to evaluate regional bond strengths of two adhesive systems to the walls of pulp chambers.
