This study aimed to evaluate the applicability of the Kvaal method in determining the age of a Serbian population. In this retrospective descriptive study, 170 dental patients (age range 16–77 years) were included. The measurements of six types of teeth were performed on digital orthopantomography radiographs according to the Kvaal method. Statistical inter-observer and intra-observer reliabilities were calculated to evaluate the reproducibility of the measurements, as well as to examine the correlation between chronological age and measured values. The evaluation revealed a substantial difference (over 12 years) between chronological and estimated age. The P ratio had the strongest correlation with chronological age for the maxillary central (r = ±0.293) and lateral incisors (r = ±0.240), whereas the pulp/root width ratio at level A had the strongest correlation for the mandibular first premolars (r = ±0.270). The lowest SD values, for measurements on teeth 15/25 (SD = 125,787), had the most accurate correlation with age. Thus, we can conclude that the original Kvaal method is not applicable in the age estimation of the Serbian population. For future research, we suggest using cone beam computer tomography as a precise technology to evaluate the applicability of Kvaal and other methods for age estimation.

Toothlessness and edentulism are conditions of stomatognathic system which directly reduce functional efficiency of masticatory system. The aim of this study was to determine the frequency of prosthetic restorations in the population of Central Serbia respondents. In a descriptive cross-sectional study, medical records of patients aged 20 to 74, who were prosthetically rehabilitated from 1st January 2014 till 1st January 2016 in public health institutions of the cities Kragujevac and Jagodina, were analyzed. 1206 dental records were checked, 577 belonged to female and 629 to male patients; there were 1730 removable dentures and 236 fixed prosthethic restorations. From removable dentures there were 723 complete upper dentures (41.8%), 487 (28.2%) complete lower dentures, 186 (10.8%) partial plate removable dentures in the upper jaw, 334 (19.2%) lower partial plate dentures. From fixed prosthethic restoration (crowns and bridges) most common prosthethic restoration was upper intercanine metal-ceramic crown 80 (33.9%). There is a statistically significant connection between cities and mobile compensation (χ2 test, p = 0.000, Cramer's V = 0.189). Statistically significant connection exists between the age of the respondent and the frequency of fixed restorations (χ2 test, p=0.002, p<0.05). Fixed restorations are significantly more frequent in the group of examinees under 65. The most common prosthetic restoration in the public-health institutions in Central Serbia cities was complete upper denture.

Introduction. Temporomandibular dysfunction (TMD) is a set of disorders that involve the masticatory muscles, the temporomandibular joint (TMJ) and its associated structures. Osteoarthritis (OA), as one of the forms of TMD, leads to permanent changes in the bone structures of TMJ. These changes can be the cause of serious functional disorders of the TMJ. Case outline. This article describes a case of a 24-year-old female patient who sought help due to pain and swelling in the area of the right and left TMJ, accompanied by muscular tension, severe headaches, which did not respond to medication. Аfter establishing the diagnosis, we have applied a therapy in the treatment of the bilateral OA of TMJ, where we used non-invasive methods. Six months later, the patient reported the absence of pain, swelling, headache, and muscle tension in the orofacial region. Conclusion. There is no “gold standard” for the management of ОА of ТМЈ. In our study, non-invasive therapy had a positive effect, where we achieved success in eliminating pain, increasing range of motion of the lower jaw, stopping the progression of the disease and advancing quality of life.

Prosthetic rehabilitation of edentulous patients and patients with one or two own teeth can be established by different treatment modalities. The most commonly used in the treatment of these patients is conventional complete denture or removable partial denture. However, due to increasing problems with this type of therapy, such as insufficient retention, stability, comfort and pain during mastication, it is suggested an overdenture supported by two natural teeth or implants. We will present series of clinical reports. In two clinical cases patients came to the dental office because of the impossibility of wearing lower partial denture, and in one case patient had problems with the upper partial denture. After clinical examination and radigraphic analysis, in all patients, dental implants were implanted. In first case there were implanted two dental implants in the region 41 and 43, in second case it was region 33, and in third case implanatiton is performed in the region of 14, 11, 21. Prosthetic rehabilitation was done after 3-months bone oseointegration period. The treatment consisted in the production of double crowns and overdentures that are retained with locator attachment. This design of the denture significantly improves the quality of patient’s life (the dentures are stable, chewing is improved, the feeling of thermal sensations of food and drink is present, the feeling of taste is complete, and the psychological patient becomes safer).
