Impact of inhalation therapy on the incidence of carious lesions in patients with asthma and COPD.

Objective: The aim of this study was to investigate the incidence of carious lesions, the amount of salivary flow rate and pH value in patients with asthma and chronic obstructive pulmonary diseases (COPD), using inhalation therapy. The obtained results were compared with the results of adult healthy subjects, forming a control group.

Material And Methods: The study included 80 participants aging between 18 and 65 years.

[The effect of gastric juice on the development of erosive changes in hard dental tissue].

Introduction: Gastroesophageal reflux disease (GERD) is an esophageal disorder where the refluxed gastric contents enters first into the esophagus followed by the pharynx, oral cavity, larynx, airway and middle ear, causing a range of disorders and symptoms. Hydrochloric acid from the gastric contents is responsible for the demineralization of dental hard tissues and release of matrix metalloproteinase from the dentin.

Objective: The aim of this study was to verify the SEM (scanning electron microscopy) analysis of the surface enamel, the enamel-dentin border and dentine after the exposure of intact teeth to filtrate of gastric contents obtained during routine endoscopy.

[Applicability of visual-analogue scale in patients with orofacial ain].

Introduction: Orofacial pain occurs in various disorders of the orofacial region.

Objective: The aim of this study was to examine applicability of the visual-analogue scale (VAS) in patients with orofacial pain (model of acute and chronic pain).

Methods: The study involved 60 patients, aged 18-70 years.

Canal wall thickness after preparation with NiTi rotary files.

Unlabelled: Root canal preparation is the most important phase of endodontic procedure and it consists of adequate canal space cleaning and shaping. In recent years, rotary instruments and techniques have gained importance because of the great efficacy, speed, and safety of the preparation procedure.

Aim: The aim of this research was to investigate measurement of maximal and minimal residual dentine thickness (RDT) and canal diameter after the canal preparation with different NiTi rotary files.

[Scanning electron microscopy investigation of canal cleaning after canal preparation with nickel titanium files].

Introduction: Root canal preparation is the most important phase of endodontic procedure and it consists of adequate canal space cleaning and shaping. In recent years, rotary instruments and techniques have gained importance because of the great efficacy, speed and safety of the preparation procedure.

Objective: The aim of this research was to investigate the influence of different NiTi files on the canal wall cleaning quality, residual dentine debris and smear layer.

[Reflux disease as an etiological factor of dental erosion].

Introduction: Gastroesophageal reflux is a frequent disease which has a significant influence on the development of dental erosions.

Objective: The aim of this research was to determine the frequency of dental erosions among the patients with gastroesophageal reflux, as well as to verify the most common symptoms of gastroesophageal disease.

Methods: The research comprised of two groups, each consisting of 30 patients aged 18-80 years.

Microleakage of contemporary composite systems in dentin cavities.

This study evaluated microleakage in vitro of self-etch and multi-step, total-etch adhesive systems. Ninety extracted non-carious human molars were randomly assigned to nine groups (n=10) and restored with nine different composite systems: Gluma CPS/Charisma, Syntac Sprint/Tetric Ceram, 3M Single Bond/Silux, Admira Bond/Admira, Optibond Solo Plus/Herculite, Trendy Bond/Saremco, Excite/Tetric Ceram, Syntac Sprint/Compoglass and Promt-L-Pop/Silux. Cavities (2 mm diameter/2 mm deep) were prepared on the facial and lingual surfaces of each tooth previously abraded with a silicon-carbide abrasion discs to produce two level dentin surfaces with whole margins in dentin.

[Multi-factoriality of dentine hypersensitivity].

Introduction: Dentine hypersensitivity has been defined as a sharp, short pain arising from exposed dentin in response to stimuli typically thermal, evaporative tactile, osmoticor, chemical and which cannot be ascribed to any other form of dental defect or pathology.

Prevalence: The most affected patients range in age from 20 to 40. The following teeth tend to be most sensitive: cuspids, premnolars and incisors, location-concentrated on the facial surface.

[Effects of fluoride in drinking water on health of deciduous teeth].

Introduction: High incidence of decayed deciduous teeth, as well as lack of adequate therapy, makes tooth decay prevention very important. One of the simplest ways to reduce tooth decay is fluoridation of drinking water. The optimal concentration of fluoride in drinking water is 1 ppm/l, and many waters naturally contain this quantity.
