The aim of this study was to determine the impact of oral health on adolescent quality of life and to compare the results obtained using standard statistical methods and artificial intelligence algorithms. In order to measure the impact of oral health on adolescent quality of life, a validated Serbian version of the Oral Impacts on Daily Performance (OIDP) scale was used. The total sample comprised 374 respondents. The obtained results were processed using standard statistical methods and machine learning, i.e., artificial intelligence algorithms—singular value decomposition. OIDP score was dichotomized into two categories depending on whether the respondents had or did not have oral or teeth problems affecting their life quality. Human intuition and machine algorithms came to the same conclusion on how the respondents should be divided. As such, method quality and the need to perform analyses of this type in dentistry studies were demonstrated. Using artificial intelligence algorithms, the respondents can be clustered into characteristic groups that allow the discovery of details not possible with the intuitive division of respondents by gender.

U radu je ispitivana osetljivost na eritromicin, tetraciklin, i ciprofloksacin 16 sojeva Campylobacter jejuni i Campylobacter coli poreklom iz cekuma brojlera, primenom disk-difuzione metode i E-testom. Od 10 ispitivanih sojeva C. jejuni, 1 soj (10%) bio je rezistentan na eritromicin, 5 (50%) na tetraciklin, a 4 na ciprofloksacin (40%) (tabela 1 i 2, grafikon 2).

Background/Aim. Dental status and oral hygiene habits are poor in young population living in deprived socioeconomic conditions. The aim of this research was to ascertain oral hygiene habits in adolescents attending high schools in urban area, determine the incidence of tooth loss at the age of 15-16 years and the gender difference. Methods. The epidemiological cross-sectional study included 234 randomly selected high school students. The research instruments were questionnaire (focusing on socio-demographic characteristics, habits, attitudes and behavior related to general and oral health) and clinical examination (tooth loss, normative need for prosthodontics restorations and presence of restorations). Results. Gender-related data comparison revealed that 32.5% of girls and 8.1% of boys had at least one tooth extracted (p < 0.05). Also, 56.2% of girls and 75.7% of boys brushed their teeth twice a day. Caries complications were identified as the indication for tooth extraction in 82.8% of participants. The data analysis confirmed the correlation between gender and tooth loss as well as treatment needs. Tooth loss was correlated with oral hygiene habits and reasons for dental visits. Treatment need was also affected by the reasons for tooth extraction and the absence of adequate prosthodontics therapy (p < 0.05). Conclusion. Sociodemographic conditions significantly influenced the number of participants with extracted teeth. A prosthodontic treatment need was influenced by the reasons for tooth extraction, adolescents' knowledge about the importance of adequate treatment and previous unpleasant experience.

Introduction/Objective Somatosensory evoked potentials are a neurophysiological tool for testing the effects of drugs in humans and animals. The aim of this study was to estimate the way that bromazepam and ibuprofen had on tooth pulp-evoked potentials (TPEPs) after non-painful stimuli, as well as to detect possible differences in this activity. Methods Sixty young healthy subjects were included in the study. They were arranged into three groups: ibuprofen, bromazepam and placebo. To record TPEPs response, dental pulp was electrically stimulated through intact enamel with non-painful stimuli. For stimulation and registration, we used Xltek Protektor 32 system, software EPWorks, version 5.0. The experiment consisted of two testing sessions. Five recordings were performed in each session. The first test session was before, and the second was 45 minutes after administration of a single dose of the ibuprofen (400 mg), bromazepam (1.5 mg) or placebo. Results The results of the present study exhibit that both ibuprofen and bromazepam significantly increased all the latencies; ibuprofen decreased amplitudes of all the waves except the first one (p < 0.05), and bromazepam decreased amplitudes of all the waves except the first one (p < 0.05); placebo did not modified TPEPs waves (p > 0.05). Additionally, there were no significant differences in influence on TPEPs between bromazepam and ibuprofen (p > 0.05). Conclusion Our study showed that both bromazepam and ibuprofen had the same influence on TPEPs after non-painful stimuli. That indicates that anxiolytic dose of bromazepam affects neurotransmission in the same manner as non-opioid analgesics ibuprofen.

Periodontal (gum) diseases present one of the main threats to oral and general health; they are very prevalent across the globe and, if left untreated, lead to tooth loss, with a significant impact on the quality of life. In addition, the impact of gum infection and inflammation on diabetes and cardiovascular disease complications has been well documented. Having in mind the key role of bacteria and the host’s immune response in the development of periodontal diseases but also the subgingival niche anatomy that complicates the adequate management of the dental biofilm and post-treatment healing, the field of periodontics is open to new or additional therapeutic methods that would complement the conventional approaches to periodontal care. Lasers were one of the first instruments used for photon therapy in dentistry due to their ability to emit a collimated, coherent light beam with monochromatic and synchronous wavelengths. We reviewed here the possibilities of the application and therapeutic effects of lasers during the initial phase of periodontal therapy using Er:YAG, Nd:YAG, CO2, and diode lasers. Therefore, the aim of this paper is to summarize the use of lasers and their clinical effects as adjuncts to the conventional, nonsurgical treatment of patients with periodontitis and to facilitate a scientific debate on this under-researched and controversial field of dental care.
