Presentation of DMFT/dmft Index in Croatia and Europe.

BACKGROUND: Dental caries is the most common oral disease affecting all age groups and a major cause of tooth loss. Although a decrease in the prevalence of dental caries has been marked across the globe, in many countries it has remained a major oral-health problem. AIM: The objective of this paper was to show the trends in the DMFT/dmft index ​​in Croatia, compare it with European countries and present further courses of action oriented towards promotion of oral health and decrease in caries prevalence. MATERIAL AND METHODS: The DMFT index databases have been generated based on online database searches for the period from 1985 to 2015. RESULTS: Croatia is one of European countries with a high DMFT index relating to 12-year old children (4.18). The experience of countries with a low DMFT index has shown that dental caries can be controlled through education and prevention activities, which eventually lead to diminished financial costs, at individual and national level, improving overall health and quality of life. CONCLUSION: Tracking and monitoring of oral health i.e. dental caries need to be improved in terms of creation of data base systems on the prevalence of dental caries, determining multi-factorial causes of its occurrence and with respect to the implementation of national oral-health prevention programs.

Trigeminal neuralgia--case and treatment analysis at the Department of Oral Surgery of the University Hospital Dubrava.

The aim of the study was to explore certain risk factors for trigeminal neuralgia (TN), assess the prevalence of misdiagnoses of TN made by primary care dentists, compare the treatment practice for TN at the Department of Oral Surgery with the guidelines, and the importance of interdisciplinary approach in TN treatment. The study included 237 patient records (70 men and 167 women, aged 5-91 years) referred to the Department under the diagnosis of TN. From their medical records, demographic data, referral diagnose, clinical diagnose, additional diagnostic procedures and treatment were analysed. Neuralgia of the trigeminal nerve affects predominantly elderly female population, while the impact of the season on the incidence of the disease has not been determined. The most common therapy used at the Department were blockades, carbamazepine or their combination. 63.3% patients were referred for further diagnostic tests following the first examination. The number of misdiagnosed cases referred by primary care dentists (33.6%) points that better training in diagnosing TN is needed for the dental practitioners. The treatment methods at the Department need to be harmonized with the latest guidelines on neuralgia treatment. Due to the complexity of etiological factors, an interdisciplinary approach is necessary.

Jaw injuries of independence victims from the 1991 War in Croatia.

In the aetiology of maxillofacial injuries, car accidents, violence, sports injuries and lately war injuries are frequently mentioned. The purpose of this study was to exhibit and analyse types of jaw injuries on bodies exhumed from massive and individual graves located in regions temporarily occupied during the War in Croatia that lasted from 1991 to 1995. The sample was the post-mortal documentation of the orofacial region (set of teeth, photographs, radiographic images) of 1068 victims exhumed from massive grave sites in Croatia. The jaw traumatism was analysed on the whole sample as well as on individual graves, whilst the analysis of trauma frequency was performed separately. Descriptive statistics were computed and the value of P < .05 was accepted as statistically significant. Results of this study showed that out of 1068 examined corpses, 332 had midface and lower face fractures, which was 31.1% of the total number. Lower face fractures were more frequent with 28.1%. Age related frequency analysis showed a significant dependency. There were 34.6% of fractures in the under 30 age group, 34.2% in those aged 30-60, while 21.3% of fractures were noted in the over 60 age group. Female bodies had the lowest number of jaw fractures regardless of the osteoporotic changes. The results of this study suggest that younger and middle aged persons were molested more. Jaw fractures suggest ante-mortal molestation. In females, the more likely fracture causes were the falls of the bodies into the graves or body to body hits.

Prevalence of third molars and pathological changes related to them in dental medicine.

The purpose of this study was to determine the prevalence of third molars in terms of respondents' age. Furthermore it was desired to determine the extent of the manifestation of pathological changes, such as caries, apical lesions, and alveolar bone resorption. This study was based on 500 OPGs of patients from the Faculty of Dentistry, University of Zagreb. Patients were divided into seven age groups. The total number of molars, the number of cavities on remaining molars, the quality of endodontic treatment and the evaluation of their performance and presence of periapical lesions was analyzed. As apart of the periodontal status, the number of inadequate fillings, the number of damaged furcations and bone resorption was analyzed. The statistical analysis was performed by means of STATISTICA 7 statistical package (StatSoft, Tulsa, USA). The correlation between the total number of molars and the age of patients was analyzed by means of Spearman's correlation to the level of significance of 0.05. The number of first, second and third molars significantly decreased in higher age groups. The prevalence of caries in third molars as compared to first and second molars was generally lower, third molars were endodontic treated at least. Assessment of involved furcations showed that the lowest percentage of 8% was found in third molars. The majority of all remaining molars had bone resorption of 1-3 mm.

Influence of hormonal status on thermography findings in breast cancer.

The aim of this study was to investigate the association of infrared imaging findings and hormone receptor (estrogen and progesterone) status in breast cancers. The study was carried out at Department of Surgical Oncology and Department of Pathology, Sestre milosrdnice University Hospital Center, in collaboration with licensed infrared thermography experts. The study involved 75 female patients with invasive breast tumors. Thermography findings were compared with different immunohistochemical findings (hormone status positive or negative). Seventy-five female patients aged 36 to 86 years, mean age 64 +/- 11.36 years, were examined. The tumor itself and the breast containing the tumor were statistically significantly warmer (p < 0.001) than the healthy breast in all study patients. There was no statistically significant difference (p > 0.05) between patients with positive and those with negative estrogen receptors. Unlike all previously published results of various thermographic studies, results obtained in this study on the hormone receptor status analyzed and its impact on thermographic findings indicated that estrogen negative tumors had a higher maximum and average temperature than estrogen positive tumors. It was also observed that estrogen negative tumors had lower impact on warming of the entire breast, and that maximum and average temperature of the affected breast was higher in estrogen positive tumors. Arithmetic means of maximum and average tumor temperatures were statistically significantly higher for progesterone negative tumors compared with progesterone positive tumors (p < 0.05). Thermographic findings correlated with the specific hormonal status of breast invasive tumors, which reflects the biological behavior of tumors as well as their clinical variables.

Displacement of a mandibular incisor--an infrequent complication of mandibular fracture.

A case of a mandibular fracture with an unusual complication is reported. A 13-year-old boy was admitted four years after conservative treatment of a symphyseal fracture. He complained of recurrent swelling. A radiographic evaluation showed a horizontally laid permanent mandibular left lateral incisor (PMLLI) that had probably slid into the fracture line and provoked repetitive infection episodes. After a surgery, a clinical and radiological analysis showed satisfactory healing.
