Oropharyngeal cancer (OPC) represents a significant portion of head and neck cancers. In most cases, it is localised in the soft palate, lingual and palatine tonsils, base of the tongue, and the surrounding tissues. Alcohol and tobacco exposure are well-known evidence-based risk factors for developing OPC; however, over the last decade, there has been a rapid increase in OPC linked to human papillomavirus (HPV). Dental implant therapy faces many challenges related to immediate and long-term success, and patients who are rehabilitated with implant prosthodontic therapy often have numerous comorbidities. Tantalum is a rare transitional metal element which has high corrosion resistance and is extremely inert. Porous tantalum trabecular metal (PTTM) has high volumetric porosity, a low modulus of elasticity, and very high friction. PTTM implant surface enhancement allows "osseoincorporation," which means the neovascularisation and formation of new bone directly onto the implant. A 65-year-old patient presented to the Department of Oral Surgery of Clinical Hospital Centre Zagreb after resection of the mandible due to OPC had oral rehabilitation. Three Zimmer Biomet Trabecular Metal™ implants (4.1 × 10 mm) were inserted in the area of lower left first incisor, lower left second premolar, and lower right second premolar, and after four months, a new upper partial denture and the bar-retained mandibular overdenture were made. Implant prosthodontic rehabilitation of head and neck cancer patients is usually challenging in terms of achieving an improvement in its main aim, quality of life; however, today it is a safe and reliable therapy. Although radiation therapy may negatively affect the patient's oral condition and influence the short- and long-term success of the implant, the presented case report showed that the excellent properties of PTTM-enhanced dental implants may give great basis for future comparative researches of using these implants in the treatment of oncologic patients.

Epidemiology of oral mucosal lesions in Slovenia.

Radiol Oncol 2018 09 11;52(3):263-266. Epub 2018 Sep 11.

Private Dental Practice, Ljubljana, Slovenia.

Background Among the diseases of oral mucosa, malignant tumors are the most dangerous, but not the most common lesions that might appear in the oral cavity. Since most of the studies are focused on the detection of cancer in the oral cavity, we were interested in detecting the frequency of benign changes of the oral mucosa in Slovene population. Oral mucosal lesions are important pointer of oral health and quality of life, especially in elderly. The prevalence of oral mucosal lesions, together with information on the risk habits associated with oral health, such as tobacco and alcohol use, can help in planning future oral health studies and screening programs. Patients and methods Survey upon oral mucosal lesions was conducted during the national project for oral cancer screening in spring 2017 in the Slovenia in which more than 50% of dentists participated and 2395 patients (904 men and 1491 women) were included. Results Clinical examination, which was conducted according to the WHO standards revealed that 645 patients (27%) had oral mucosal lesions. The ten most common oral lesions detected were fibroma, gingivitis, Fordyce spots, white coated tongue, cheek biting, linea alba, denture stomatitis, geographic tongue, recurrent aphthous ulcerations and lichen planus. Conclusions Overall, these epidemiological data suggest need for specific health policies for prevention, diagnosis and treatment of oral mucosal lesions.

SUBJECTIVE ASSESSMENT OF CROATIAN DENTAL MEDICINE STUDENTS ON THEIR KNOWLEDGE AND SKILLS IN PROSTHODONTICS.

Acta Stomatol Croat 2017 Dec;51(4):271-282

Department of Prosthodontics, School of Dental Medicine, University of Zagreb, Zagreb, Croatia.

Objectives: The aim of the study was to establish the subjective perception of dental medicine students' knowledge and skills in prosthodontics and to determine both how their perception changed during their study, by gaining clinical experience. Also, the aim was to investigate if there were any socio-demographic factors that influenced students' perception.

Methods: The research, based on an anonymous survey for dental medicine students was carried out at the School of Dental Medicine, University of Zagreb in 2015. YES/NO/DO NOT KNOW questions were used for assessment of students' knowledge, and a 50 mm visual analog scale was used for assessment of their abilities and skills. The Chi-square test, t-test for independent samples, analysis of variance and the Pearson's correlation coefficient were used for statistical data analysis.

Results: Students' response (4th, 5th and 6th year of study) to the study amounted to 71,3%. The results showed that clinical experience and the number of correct answers from knowledge assessment increased with the year of study. Students with completed dental laboratory technician school took statistically significantly larger number of impressions and fabricated a significantly larger number of fixed restorations. Additionally, the results showed a significantly higher level of agreement with the statements about their perception of knowledge and skills.

Conclusion: Students' perceptions on learning positively correlated with the number of completed semesters in prosthodontics and the students' own clinical experience.

Treating patients with HIV and Hepatitis B and C infections: Croatian dental students' knowledge, attitudes, and risk perceptions.

J Dent Educ 2011 Aug;75(8):1115-26

Department of Prosthodontics, School of Dental Medicine, University of Zagreb, Gunduliceva 5, HR-10000 Zagreb, Croatia.

Dentists and dental students can be exposed to the human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) during routine work. The aims of this study were to assess a group of dental students' knowledge about HIV, HBV, and HCV infections; assess their attitudes and risk perceptions about the treatment of patients with HIV, HBV, and HCV; and identify factors associated with their knowledge and willingness to treat these patients. An anonymous survey was administered to 534 predoctoral students at the School of Dental Medicine, University of Zagreb, Croatia. The response rate was 71.9 percent. Students' knowledge increased with each year of study. Senior students (in their third, fourth, and fifth years) had more professional attitudes and were significantly more positive about dentists' professional obligation to treat patients who are HIV-positive than were junior students (in their first and second years; p=0.0002). Senior students also expressed significantly more willingness to treat intravenous drug users and patients with hepatitis (p=0.016 and p=0.033, respectively). Female students were significantly more convinced than male students that routine dental treatment carried a significant risk of HIV and hepatitis infection (p=0.025). These students' knowledge negatively correlated with the lack of willingness to treat intravenous drug users and patients with hepatitis, and they expressed their willingness to receive further theoretical and practical education on this topic.

[Temporomandibular disorders and headaches].

Acta Med Croatica 2008 May;62(2):179-87

Zavod za stomatolosku protetiku, Stomatoloski fakultet Sveucilista u Zagrebu, Zagreb, Hrvatska.

Temporomandibular disorder (TMD) is a common name for a series of pathologic conditions with similar signs and symptoms, which can lead to a disturbed and altered function of the stomatognathic system. Most of these conditions are of a multifactorial etiology, which can pose difficulties in obtaining a precise and accurate diagnosis. However, TMD is an ever more common and serious problem in contemporary dental practice and at general medical offices, so a more systematic approach in its diagnosis including data collection and interpretation is necessary. Accordingly, accurate diagnosis of TMD requires proper identification and classification of the dysfunction, as well as recognition of the mechanism and origin of pain occurrence.

Prevalence of root dilaceration in adult dental patients in Croatia.

Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2006 Jul 28;102(1):104-9. Epub 2006 Feb 28.

Department of Endodontics and Restorative Dentistry, School of Dental Medicine, University of Zagreb, Gundulićeva 5, 10000 Zagreb, Croatia.

Objective: To determine the prevalence and distribution of dilaceration in all tooth groups by using radiographs.

Study Design: The sample included 953 periapical intraoral radiographs and 488 panoramic radiographs from different caucasian patients. The ages of the patients ranged from 18-65 years. Dilaceration of the root was detected by measuring the degree of deviation from the long axis (deviation ł 90 degrees), and evaluating the "bull's eye" appearance. The prevalence of root dilaceration for each tooth-type was expressed in percentages.

Results: The teeth showing the highest prevalence of root dilaceration were mandibular third molars (24.1%), maxillary first molars (15.3%), second molars (11.4%) and third molars (8.1%). In the mandible, dilacerations were less common than in the maxilla.

Conclusions: In the adult population examined in Croatia, dilaceration was most frequently found to affect posterior teeth.
