Introduction: Antiresorptive drugs (AR) have been used for many years in the treatment of various bone conditions such as osteoporosis, osteopenia, Paget's disease, bone metastases, multiple myeloma and the associated malignant hypercalcemia. As a side effect of AR therapy, medication-related osteonecrosis of the jaw, which affects the mandible more commonly than the maxilla, (MRONJ) has become an increased risk regarding patients' health and quality of life. The incidence of osteonecrosis has increased significantly in the last few years. One of the main methods of the disease prevention is the education of patients and doctors of dental medicine (DDMs). This is evidenced by the national program of information and prevention of antiresorptive therapy side effects, which was also the impetus for this study.

Purpose: This study aims to test the knowledge of DDMSs on AR, especially on bisphosphonate (BF) therapy, MRONJ as well as on the risk factors of the disease itself.

Material and methods: 458 DDMs from the Republic of Croatia participated in the survey and responded by an anonymous questionnaire to questions about the knowledge of AR/BF and the risk of MRONJ.

Results: The results showed that 36.68% of DDMs do not know that MRONJ is the main complication of AR/BF therapy. The results are significantly different in terms of academic degree, specialization, workplace, and work experience. 60.26% of respondents do not know the main indications for AR/BF use, 53.26% do not know the factors affecting the onset of the disease, and 42.58% do not know which therapy is not recommended for patients on AR/BF therapy. 93.89% of respondents expressed the desire to educate on this issue. This current study was carried out to further investigate the pilot study findings which was conducted in the year 2015, but it had a significantly lower number of participants.

Conclusion: This research suggests that further education of DDMS on this topic is necessary to prevent or to start early treatment of MRONJ.

Objectives: Dental caries first occurs within primary dentition in toddlers and preschool children, in a form of early childhood caries (ECC). In every day's busy and employment burdened parenting, caretakers and institutions have become important even more nowadays, not only for forming child general behavior and character, but also for maintenance of their general and oral health as well.

Aims: To evaluate the presence and severity of ECC in children who attended public kindergartens in Sarajevo, and to offer basic information for the maintenance and improvement of child oral health to their parents and kindergarten teachers.

Methods: The study included 1722 preschool children aged 3-6 years who attended kindergartens within Sarajevo public kindergarten institution, together with their parents and kindergarten teachers. Dental team members gradually visited all kindergartens situated in four Sarajevo city municipalities and examined kindergarten children according to the WHO Oral Health Survey Manual. Oral health promotion material for parents and kindergarten teachers was also distributed simultaneously during sequential visits.

Results: ECC was present in preschool kindergarten children in Sarajevo, with its high prevalence (67.71%); dmft-value (3.97) and severity (SiC index 8.79). There was also a significant lack of dental healthcare to examined children mostly related to lack of visiting dental offices by children's parents (CI=10.55%, RI=10.80%, TI=12.98%).

Conclusion: Parental role in preserving and improving of their children oral health should be systematically and profoundly improved. Kindergarten officials and staff should recognize the importance of anticariogenic diet menus and oral hygiene maintenance within their institutions.

Objectives: Molar crown wear is often used in bioarchaeological research as a proxy for age at death. However, a small number of researchers have used premolars or compared the application of different methods of relative age estimation.

Material and methods: Using a sample of 197 previously extracted maxillary first premolars from US dental patients, we considered three protocols for estimating age: the Bang and Ramm/Liversidge and Molleson (BRLM) age estimate method, occlusal topographic analysis, and the Smith system of macrowear scoring. A previous study utilizing the Bang and Ramm method yielded an age estimate range of 9.4 to 10.8 years for the sample.

Results: Our analyses showed no associations between occlusal topography parameters (occlusal slope, relief, or faceting) and BRLM age estimates, but some concordance was found between Smith scoring and BRLM ages estimates and between Smith scoring and occlusal topography parameters.

Conclusion: The results of the present study suggest that relationships between gross tooth wear, tooth shape, and dental age estimates are complex, and available methods should be considered together to gain a more comprehensive understanding of how teeth change their shape with wear throughout the lifecourse.

Objective: The increasing significance of medicolegal evaluation following maxillofacial traumatic events constitutes a complex issue. This clinical research aimed to assess the current etiology of oral and maxillofacial injuries in Portuguese population.

Material and methods: An epidemiological clinical observational study was conducted in Centro Hospitalar Lisboa Norte on a sample of 384 subjects diagnosed with oral and maxillofacial trauma, between 2018 and 2020. Data were collected through clinical reports and analyzed using SPSS version 27.

Results: Women and men were nearly identical in the number and distribution, with 49.5% females and 50.5% males. In 2020, there was a decrease in the number of traumatic incidents compared to other years. Falls or accidental descents were found to be the most common cause of injury, accounting for 44.3%, followed by assaults accounting for 24.7%. A total of 84 subjects exhibited soft tissue injuries related to periodontal region. The upper central incisors (174) were the most frequently affected teeth with uncomplicated fractures, and the predominant form of treatment was the administration of pain medication.

Conclusion: A correlation between falls or accidental descents, female subjects, and advancing age, as well as between assaults, male subjects, and adults, has been established. Falls or accidental descents and assault were the predominant etiologies, and the year 2020 exhibited a decrease in the incidents of traumatic events.

Objectives: Smokers with periodontitis are therapeutically challenging. Azithromycin (AZM) may be used as an adjunct to periodontal treatment. The aim of this randomized, double-blind, controlled clinical study was to determine the effect of azithromycin in shallow, moderate, and deep pocket depths in smokers when combined with non-surgical periodontal treatment.

Material and methods: Forty-nine patients who smoked at least 20 cigarettes per day for more than 5 years were included in the study; however only 40 completed it. The number of teeth, plaque index (PI), gingival index (GI), PPD, CAL, bleeding on probing (BOP) and gingival recession were recorded at baseline and months 1, 3 and 6. The pocket depths (PD) were grouped as shallow, moderate, and deep. Twenty-four patients assigned to the AZM+ (test) group received AZM (500 mg tablets) once a day for 3 days, beginning on the first day of SRP.

Results: The decline in the total number of pockets in all groups was statistically significant from baseline to 1^st, baseline to 3^rd, baseline to 6^th; and from 1^st to 3^rd and 1^st to 6^th months. There was a statistically significant increase in the number of shallow pockets between baseline and 3^rd, baseline and 6^th; and 1^st and 6^th months (p=0.000) for both groups.

Conclusion: Antibiotic administration significantly increased the number of shallow pockets at all time points. However, larger scale controlled clinical studies are needed to verify the efficiency of AZM in smoker periodontitis patients.

This is the first case report where two patients were under uniform denosumab administration protocol in diffuse sclerosing osteomyelitis (DSO) treatment and were closely monitored for 18 months. Objectives: This study aimed to describe the beneficial effects of denosumab in DSO treatment as well as pain relief and the significant lack of long-term use due to poorer outcomes after repeated use. DSO of the jaw is a poorly understood rare chronic disease the treatment of which is still very challenging despite a rapid development of medicine. Different medical treatments have been proposed without any significant long-lasting success. Bisphosphonates have offered substantial clinical benefit in DSO therapy, but due to harmful pharmacodynamic properties, denosumab therapy has been used to replace bisphosphonate therapy. Patients had a reduction in pain intensity with each subsequent application of denosumab but with less success than the first administration of denosumab. This case report has shown that denosumab could be a promising conservative treatment option for pain treatment in patients suffering from DSO.

Background: General anesthesia is a well-documented therapeutic option for the provision of dental treatment, particularly in patients with special healthcare needs and uncooperative pediatric patients.

Objectives: This retrospective study aimed to analyze the characteristics of dental general anesthesia (DGA) procedures for uncooperative patients of all ages in a tertiary healthcare facility, Clinical Hospital Dubrava, in Zagreb, Croatia.

Material and methods: The hospital records for the patients treated for various dental reasons under GA were obtained at the Clinical Hospital Dubrava in Zagreb, Croatia.

Results: Between 2014 and 2019, a total of 810 DGA procedures were performed including 607 patients. The median age was 18 years. Almost half of the patients referred to undergo DGA procedures were from the City of Zagreb and Zagreb County, 27.8% (N=225) and 21.0% (N=170), respectively. More than 90% of patients undergoing DGA procedures were referred with 1 to 3 medical conditions. 47.9% of patients had 1 to 3 dental conditions, of which caries was the most common condition (95.7%). The mean waiting time (±SD) was 113.06 (±62.62) days. 90 patients (14.8%) were referred for dental procedures under GA more than once, accounting for 203 procedures (25.1%).

Conclusions: DGA remains a single dental treatment option for specific individuals. There is an institutional and, also, an organizational need to address the long waiting times and high repeated DGA rates.

Objectives: Estimating age is a crucial determinant of forensic science. Various methods have been used to estimate dental age (DA) and skeletal age (SA).The aim of the current study was to compare the Cameriere's DA method with the Cameriere's SA method in estimating CA in children.

Materials and methods: A total of 216 radiographs of 130 females and 86 males (between 9 to 14.99 years of age) were evaluated in northwestern Turkey. DA was calculated on the panoramic images using Cameriere's open-apex method. SA was determined on the lateral cephalograms using the fourth cervical vertebrae method by Cameriere. The DA, SA, and CA data were compared using a paired t-test and Wilcoxon test.

Results: The mean CA of all groups was calculated as 12.96±0.30, the mean DA of 12.74±0.68 and the mean SA of 12.89±0.89. In males, the DA method presented an underestimation between ages of 14.00 and 14.99 (p<0.05) and an overestimation between ages 9.00 and 11.99 (p<0.05). In females, the DA method showed an underestimation in the 13.00- and 14.99-year-old age groups (p<0.05) and an overestimation in the 10.00- and 11.99-year-old age groups (p<0.05). The SA method revealed a significant underestimation in females between the ages of 13.00 and 14.99 and in males between the ages of 14.00 and 14.99 (p<0.05).

Conclusions: The SA estimation method may provide more accurate results compared to the DA method with children of both sexes aged between 9.00 to 12.99 in the determination of CA.

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.

Objective: This study evaluated in vitro, the effects of carbamide peroxide 10% (CP) associated with Carbopol® (CP-ct) and Aristoflex® (CP-at) thickeners on human gingival fibroblasts (HGF) cytotoxicity and assessed in situ their effects on dental enamel.

Material and methods: The cytotoxicity was analyzed using MTT - Vybrant® proliferation test. For in situ stage, 144 bovine enamel/dentin blocks were randomized into seven groups (n=12). Samples were stained, fixed in intraoral palatal devices and bleached for 4 h, during 14 days, with: Carbopol thickener (ct), Aristoflex thickener (at), CP-ct, CP-at, CP without thickener (CP-wot), Commercial CP (CP-com). The samples had their microhardness (SMH), roughness (Ra) and color analyzed using a microdurometer, a rugosimeter and a spectrophotometer, respectively. The analyses were performed at baseline and 24-h after completion of tooth bleaching.

Results: Different thickeners were similar regarding their cytotoxicity. The experimental gels with Carbopol exhibited lower SMH values, while the groups treated with CP exhibited higher Ra values. For the color change results, the groups treated with CP had values above the acceptability and perceptibility limits.

Conclusion: CP-at was able to promote an effective bleaching with less alterations of the tooth surface compared to the CP-ct. Hence, Aristoflex stands as a promising thickener in conjunction with CP in order to preserve the physical properties of dental enamel after home bleaching.
