Introduction: Artificial intelligence has been applied in various fields throughout history, but its integration into daily life is more recent. The first applications of AI were primarily in academia and government research institutions, but as technology has advanced, AI has also been applied in industry, commerce, medicine and dentistry. Objective: Considering that the possibilities of applying artificial intelligence are developing rapidly and that this field is one of the areas with the greatest increase in the number of newly published articles, the aim of this paper was to provide an overview of the literature and to give an insight into the possibilities of applying artificial intelligence in medicine and dentistry. In addition, the aim was to discuss its advantages and disadvantages. Conclusion:The possibilities of applying artificial intelligence to medicine and dentistry are just being discovered. Artificial intelligence will greatly contribute to developments in medicine and dentistry, as it is a tool that enables development and progress, especially in terms of personalized healthcare that will lead to much better treatment outcomes.

Objectives: The study aimed to determine the relationship between the mandibular asymmetry index according to Kjellberg between patients with painful unilateral anterior disc displacement (DD) and asymptomatic volunteers without disc displacement. Vertical measurements were performed on a panoramic single-image radiograph, and the disc status was confirmed by magnetic resonance imaging (MRI). Material and methods: Two groups of subjects were retrospectively selected, 40 patients (the overall mean age was 35.5 years; 75% female) with temporomandibular disorder symptoms confirmed by RDC/TMD axis I and manual functional analysis. Unilateral DD was determined by MRI. A comparative group of asymptomatic volunteers (20 dental students with a mean age of 23.4 years; 72% female) had the physiological position of the disc determined by MRI. The vertical asymmetry of the condyle was determined by the method of Kjellberg et al. The symmetry of the gonial angle of the mandible was also measured. Results: A comparison of the mean of the asymmetry index between patients (average 90.89±7.08%) and asymptomatic volunteers (mean 95.86±4.44%) showed a statistically significant difference (p=0.0029). There was no difference (p=0.088) in gonial angle symmetry between the patients (mean 96.48±2.96°) and the asymptomatic volunteers (mean 97.52±2.31°). The distribution of the presence of individual DD diagnoses (partial and total displacement with reduction, displacement without reduction) in patients diagnosed with asymmetry of the mandible was without statistical significance (p>0.05). Conclusion: This study actually points to the asymmetry of the mandible as a potential morphological risk of anterior DD.

Objectives: Dental profession is characterized by a high risk of injuries at work due to exposure to specific working conditions. The operating area in a patient’s mouth is small, and it is handled by a large number of sharp instruments and drills that rotate at high speed, which creates an aerosol contaminated with particles of saliva and blood. This poses a risk of transmitting infections from patients to the dentist through stabbing incidents and cuts, which are some of the most common occupational injuries that are reported in the scientific literature. Objective: The aim of this study was to examine the frequency of occupational injuries among dentists in Croatia, to establish most common injuries, and to determine the main risk factors. The aim of this research was also to determine the dentists’ opinion on causes that are responsible for the occupational diseases and injuries. Material and methods: The survey was conducted based on a sample of 406 dentists from Croatia as respondents to an electronic survey. Results: 63.05% of the respondents suffered injuries caused by dental practitioners. The most common injuries were needle puncture incidents (57.75%) and cuts (20.86%), followed by eye injuries (13.37%), patient bite (4.81%) and punches (1.60%). The largest number of respondents stated the improper posture as the most important cause of occupational diseases and injuries, followed by stress, infection and noise. Conclusion: knowledge of risk factors is the first step of injury prevention. Our respondents were largely aware of the dangers surrounding them. Nevertheless, the frequency of injuries was high and there is still a need for preventive measures to minimize the frequency of injuries in dentistry.

Objective: Turner syndrome (TS) and Klinefelter syndrome (KS) represent the two most common X chromosome aneuploidies, each associated with systemic disruptions to growth and development. Effects of these conditions on tooth crown morphology are explored in a sample of Croatian individuals. Material and Methods: The sample included 57 TS, 37 KS and 88 control individuals. Dental crown morphology was scored on dental casts according to the Turner-Scott Dental Anthropology System. Results: Incisor shoveling and the hypocone were significantly different between TS individuals and both control and KS individuals. Individuals with TS exhibit lower grades of expression than either group. Furthermore, the number of lingual cusps on the mandibular premolars, the hypoconulid on the mandibular second molar, and cusp 7 on the mandibular first molar were significantly different, though pair-wise comparisons did not elucidate these differences. Tuberculum dentale, distal accessory ridge, and Carabelli’s trait were expressed similarly to the control. KS individuals were not significantly different from control individuals for any trait, though this may be related to sample size. Conclusions: Previous studies suggest the loss of an X chromosome has a reducing effect on dental crown morphology, which is confirmed in this research. TS individuals exhibit generally simpler dental morphology compared to the control sample, though some traits are expressed comparably to the control sample. The effects of KS are less clear. Though previous studies suggest that the presence of an extra X chromosome increases dental crown dimensions, there was no notable effect on crown morphology in this study.
