Selected methods for the early diagnostics of oral malignant lesions – a literature review

Early diagnostics of oral cancerous lesions plays a crucial role in the process of treatment and evaluation of the patient's chances for recovery. The article presents new techniques of identifying and detecting abnormal lesions within oral mucosa, such as oral lumenoscopy (ViziLite), TBlue (toluidine blue marking system), VELscope screening system, OralCDx and the brush biopsy. Their application does not allow a definite diagnosis, nor does it replace biopsy or histopathologic assessment, but it permits a more accurate examination of the oral cavity, as well as oral lesion detection at the early stage of progression

The Self Adjusting File – a review. New system, a new look into the root canal space?

The Self Adjusting File (SAF) is the only representative among endodontic files which enables preparation of the surface of a tooth with irrigation. Nickel-titanium alloy in the form of a grid allows to adjust the flexible file to the canal wall and expand according to its three-dimensional anatomy. Simultaneous rinsing increases the efficacy of cleaning. Unlike most of the available systems endodontic rotary motion was replaced by movement in the vertical axis. The cutting blade characteristic for conical cores turned into an abrasive surface. The combination of in and out movements with the abrasive surface resembles the effect of sandpaper. The first part of the paper takes into account the description of The Self Adjusting File and its the manner of operation while the second is a description of its characteristics in the clinical aspect

Application of Metagenomic Analyses in Dentistry as a Novel Strategy Enabling Complex Insight into Microbial Diversity of the Oral Cavity

The composition of the oral microbiome in healthy individuals is complex and dynamic, and depends on many factors, such as anatomi­cal location in the oral cavity, diet, oral hygiene habits or host immune responses. It is estimated at present that worldwide about 2 billion people suffer from diseases of the oral cavity, mainly periodontal disease and dental caries. Importantly, the oral microflora involved in local infections may spread and cause systemic, even life-threatening infections. In search for etiological agents of infections in dentistry, traditional approaches are not sufficient, as about 50% of oral bacteria are not cultivable. Instead, metagenomic analyses are particularly useful for studies of the complex oral microbiome – both in healthy individuals, and in patients with oral and dental diseases. In this paper we review the current and future applications of metagenomic studies in evaluation of both the composition of the oral microbiome as well as its potential pathogenic role in infections in dentistry

Surveys of public knowledge and attitudes with regard to antibiotics in Poland: Did the European Antibiotic Awareness Day campaigns change attitudes?

BACKGROUND:Antimicrobial resistance is a global public health problem. Monitoring the level of knowledge regarding antibiotics is a part of the European Union Community strategy against antimicrobial resistance. OBJECTIVE:To assess knowledge by the general public in Poland regarding antibiotics, AMR, and the impact of the European Antibiotic Awareness Day campaigns. METHODS:The repeated cross-sectional study was developed and carried out among the general public in Poland (in 5 waves between 2009 and 2011, embracing a total of 5004 respondents). The survey was based on a self-designed questionnaire, and carried out by Millward Brown SMG/KRC, using Computer Assisted Telephone Interviews (CATI). RESULTS:A high percentage of Polish adults had used antibiotics within the 12 months preceding their participation in the study (38%). Statistically relevant differences were observed regarding the respondents' gender, age, education and employment status. The majority of the antibiotics used were prescribed by physicians (90%). In all five waves, 3% of the respondents purchased an antibiotic without a prescription. Prescriptions were mostly obtained from a general practitioner. The prevailing reasons for taking antibiotics were the common cold, sore throat, cough and flu. Approximately 40% of the respondents expected a prescription for an antibiotic against the flu. The vast majority knew that antibiotics kill bacteria (80%) but at the same time 60% of respondents believed antibiotics kill viruses. Physicians, pharmacists, hospital staff and nurses were mentioned as the most trustworthy sources of information. A third of the respondents declared to have come across information on the prudent use of antibiotics in the preceding 12 months. In the fifth wave, nearly half of the participants (48%), who had come across information about antibiotics in the preceding 12 months declared that the information resulted in a change in their attitude towards antibiotic use. CONCLUSION:The survey generated information about the knowledge, attitude, and behavior regarding antibiotics among the general population of Poland. Inappropriate antibiotic use is still highly prevalent in Poland, although a positive trend in behavioral change was observed after the educational campaigns. Additional didactic and systematic education campaigns regarding appropriate antibiotic use are needed and the use of the Internet as an education tool should be enhanced

Prevalence of erosive lesions with respect to risk factors in a young adult population in Poland-a cross-sectional study.

OBJECTIVE The study was conducted to investigate the prevalence of erosive lesions and related risk factors in the population of 18-year-old young adults in Poland. MATERIALS AND METHODS Calibrated examiners measured erosive tooth wear according to Basic Erosive Wear Examination (BEWE) scoring system in 1869 patients and assessed the impact of risk factors with a questionnaire. RESULTS Erosion was present in 42.3% of the patients. Early damage to the enamel was the most frequent finding (BEWE 1)-28.9%. More advanced lesions (BEWE 2) were observed in 12% of the patients. Advanced damage to the teeth (BEWE 3) was diagnosed rarely-1.4% of the examined population. Acidic diet, hygienic habits, and medical conditions such as asthma, eating disorders, and esophageal reflux showed statistical significance, as associated with erosion in the examined population. CONCLUSIONS The present study indicates that dental erosion is a common oral disease in the 18-year-old population with prevalence of frequency and intensity in males. However, on the basis of observations carried out in recent years, it may be assumed that the prevalence of this type of lesion is increasing. CLINICAL RELEVANCE Present findings support other longitudinal studies toward evaluation of the BEWE system as a valuable standard for assessing erosive and related risk factors among different populations
