This study aims to determine the correlation between the mean value of bone density measured on the CBCT device and the primary stability of dental implants determined by resonant frequency analysis. An experimental study was conducted on a material of animal origin: bovine femur and pig ribs. Two types of implants were used in this study: self-tapping and non-self-tapping of the same dimensions. Results of the experimental study showed a statistically significant correlation between bone density expressed in HU units and the primary stability of self-tapping and non-self- tapping dental implants expressed in ISQ units in bovine femur bones and self-tapping implants and pig rib bones. There was no statistically significant correlation between non-self-tapping dental implants in pig rib bones. Self-tapping and non-self-tapping implants did not show statistical significance in the primary stability in bones of different qualities. The analysis of bone density from CBCT images in the software of the apparatus expressed in HU units can be used to predict the degree of primary stability of self-tapping and non-self-tapping dental implants in bones of densities D1 and D2, and self-tapping dental implants in bones of the lower quality D4.

We present a very rare case of a child with nine supernumerary teeth to analyze the potential, benefits, and limitations of artificial intelligence, as well as two commercial tools for tooth segmentation. Artificial intelligence (AI) is increasingly finding applications in dentistry today, particularly in radiography. Special attention is given to models based on convolutional neural networks (CNN) and their application in automatic segmentation of the oral cavity and tooth structures. The integration of AI is gaining increasing attention, and the automation of the detection and localization of supernumerary teeth can accelerate the treatment planning process. Despite advancements in 3D segmentation techniques, relying on trained professionals remains crucial. Therefore, human expertise should remain key, and AI should be seen as a support rather than a replacement. Generally, a comprehensive tool that can satisfy all clinical needs in terms of supernumerary teeth and their segmentation is not yet available, so it is necessary to incorporate multiple tools into practice.

Background and objectives: Atherosclerotic cardiovascular disease (ASCVD) remains a major global cause of mortality, with chronic infections and systemic inflammation, including those arising from periodontal pathogens, contributing to vascular pathology. This study aims to investigate the presence of bacterial DNA from oral cavity microorganisms in atherosclerotic plaques of patients with abdominal aortic aneurysm (AAA) and to explore correlations with oral health indices and clinical variables. Materials and Methods: Forty patients (mean age 61 ± 6 years; 60% male) with periodontitis and AAA were included. Subgingival biofilm and arterial plaque samples were analyzed using PCR for A. actinomycetemcomitans, P. gingivalis, P. intermedia, T. forsythensis, and T. denticola. Dental indices (PI, GI, SBI, and PPD) were determined in all patients, and concordance of the findings was assessed by Cohen’s κ, and correlations were evaluated using Spearman’s coefficient. Results: P. gingivalis exhibited the highest concordance between oral and arterial plaques, followed by T. forsythensis and A. actinomycetemcomitans. T. denticola DNA was not detected in aortic samples. Positive correlations found between A. actinomycetemcomitans and P. gingivalis with dental indices were found to be statistically significant. Conclusions: The detection of periodontal pathogens, particularly P. gingivalis and T. forsythensis, in both oral and arterial plaques supports their potential role in atherosclerotic and aneurysmal changes. The findings highlight the relevance of periodontal health in cardiovascular risk prevention and the need for longitudinal studies to reveal causal mechanisms.

According to numerous studies conducted here and abroad, ailments of the bone support surrounding teeth are common among humans. Pathological symptoms occur with gingiva inflammation which later on spreads and leads towards the changes of deeper periodontal tissues. This paper deals with the current conditions of oral hygiene and its influence on prevalence as well as health risks of Kosovo and Metohija residents from periodontal and gingivitis. Research has been conducted on 120 subjects of the age from 20 to 60 years with slightly more male participants. After the examination of all subjects, 9.7 % males and 44.8% females had healthy gingiva. Results show notably better gingiva condition with females. 11.66% subjects had healthy periodontals while 40% had early symptoms of gingiva inflammation. Periodontal pockets with 4 to 5 mm depth were found on 15% of examinees, while the most serious symptoms of periodontal disease were found only on 3.33% of male examinees. Compared statistical results show that, according to CPITN index, periodontal disease is significantly less common among female participants than among males. According to approximately- spatial Plaque index, high oral hygiene is found only among non-smokers or precisely among 13% of all examinees. Low oral hygiene was recorded with 21.67% smokers and 14% non-smokers. According to results we can conclude that gingiva health condition as well as health condition of the whole support surrounding teeth apparatus among the northern part Kosovska Mitrovica residents, is on the higher level among females than among males. Also, considering the same examinees, results show that oral health is higher among non-smokers than among smokers. These results show the need for further activity of preventive services in raising consciousness on oral health importance as well as for the conducting appropriate measures concerning oral hygiene with northern part of Kosovska Mitrovica residents.

Eradication of microorganisms present in the root canal system during endodontic therapy is one of the critical factors affecting the final outcome of endodontic treatment. However, even adequate technique of the root canal treatment and use of irrigants according to the established protocol does not lead to the complete elimination of microorganisms during endodontic treatment. The presence of Enterococcus (E.) faecalis inside the root canal system may be an important factor contributing to the failure of the treatment. Introducing agitation techniques in irrigation, such as passive ultrasonic irrigation (PUI) and the use of the activating instrument XP-endo Finisher (XPF), contribute to a better debridement and disinfection of the root canal. This study was conducted on 42 root canals experimentally inoculated with E. faecalis and exposed to three irrigation protocols. These have included a standard irrigation protocol using a syringe and needle, passive ultrasonic irrigation, and activation of the irrigant using an XPF instrument. The reduction in microorganisms was evaluated using the quantitative polymerase chain reaction in real-time (RT-PCR) as well as via the method of determining the number of colony forming units on nutrient medium (CFUs). The results of this study showed that the use of supplementary irrigation protocols, PUI, and XPF led to a significant decrease in the number of microorganisms inside the root canal of experimental teeth. These findings indicate a significant positive impact of these procedures on the disinfection of the root canal system.
