Dijagnostičke metode u oralnoj medicini - diplomski rad
No full textOralna medicina predstavlja interdisciplinarnu oblast stomatologije koja se bavi dijagnostikom i lečenjem oboljenja kože i sluznice usne duplje, pljuvačnih žlezda i orofacijalne regije. Dijagnoza u oralnoj medicini je kompleksna i zahteva integraciju iscrpnih podataka iz anamneze, kliničkog pregleda, dijagnostičkih testova, radioloških metoda i konsultativnih pregleda specijalista drugih grana medicine.
Savremene dijagnostičke metode, uključujući molekularne i imunohistohemijske tehnike, dopunjuju klasične pristupe i omogućavaju rano otkrivanje prekanceroznih i malignih promena. Rad se zasniva na standardnoj literaturi, pre svega „Burket’s Oral Medicine“, „Cawson’s essentials of oral pathology and oral medicine“, kao i relevantnim publikacijama sa PubMed-a i studentskim predavanjima
Tunel ili slot preparacija u zbrinjavanju lezija na aproksimalnim površinama zuba - diplomski rad
No full textMastikatorna efikasnost pacijenata sa različitim stadijumima parodontitisa - diplomski rad
No full textParodontitis predstavlja hronično inflamatorno oboljenje, karakterisano
progresivnom destrukcijom parodontalnih tkiva. U terminalnim stadijumima dolazi do
labavljenja, patološke migracije i gubitka zuba, što može narušiti funkcionalni
integritet stomatognatnog sistema. Etiologija bolesti je multifaktorijalna, pri čemu
dentalni biofilm predstavlja osnovni etiološki faktor, dok predisponirajući i
modifikujući faktori utiču na aktivaciju imunoinflamatornog odgovora domaćina, koji
dovodi do destrukcije parodoncijuma. Mastikacija je osnovna oralna funkcija,
obuhvata mehaničko usitnjavanje hrane i predstavlja prvi korak digestivnog procesa.
Kod pacijenata sa uznapredovalim parodontitisom javljaju se promene u obrascima žvakanja kako bi se kompenzovalo labavljenje i gubitak zuba. Kliničke manifestacije,
uključujući labavljenje zuba, gubitak okluzalnih kontakata i unilateralnu mastikaciju,
narušavaju biomehaničku ravnotežu žvakanja. Dodatno, opterećuju preostale zube i
mogu izazvati poremećaje temporomandibularnih zglobova. Kauzalna terapija
predstavlja osnovni terapijski pristup, čiji su ciljevi eliminacija inflamacije i
obnavljanje bioloških kapaciteta parodontalnih tkiva uklanjanjem supra- i
subgingivalnih naslaga i akcesornih faktora. Efikasna primena terapije doprinosi
očuvanju parodontalnog zdravlja i može doprineti poboljšanju mastikatorne funkcije,
što ima direktan uticaj na kvalitet života pacijenata.
Mastikatorna efikasnost procenjivana je testom žvakaćih guma (u dve boje), a
sposobnost putem upitnika, pre i osam nedelja nakon terapije.
Očekuje se da sprovođenje kauzalne terapije dovodi do poboljšanja
mastikatorne funkcije kod pacijenata sa parodontitisom, naročito u ranim stadijumima
bolesti, čime bi se ukazalo na značaj ove terapijske intervencije, u očuvanju oralnih
funkcija
Evaluation of HRCT parameters that could predict surgical complications in patients with otosclerosis - A pilot study
No full textPurpose/Objectives
In order to avoid intraoperative surgical complications during stapes surgery for otosclerosis, middle ear anatomy assessment in
preoperative HRCT plays an important role. As stated in the literature, preoperative HRCT should provide information about the
width of the oval window of the niche (Wown), depth (Down) and facial-promontory angle (FPA), preferably cochlear aqueduct
dimensions and possible inner ear malformations. The aim of this study was to determine if these morphological parameters and
conditions differ between the group of patients with otosclerosis and the control group, thus whether they are determined by this
specific condition.
Methods and materials
This prospective study included 37 patients with radiologically detectable foci of otosclerosis (47 ears) and 41 patients with a
diagnosis of noise-induced hearing loss. Their HRCT scans of the temporal bones were analysed for the previously mentioned
morphological parameters and presence of inner ear malformations.
Result
FPA, Wown and Down showed overall lower values in otosclerotic compared to the control group, but with the significant
decrease only in the value of FPA (p=0.034). Cochlear aqueduct dimensions showed a slight increase in length in otosclerotic
patients but without significant difference. Regarding inner ear malformations, we detected only one patient with enlarged
vestibular aqueduct in the control group.
Conclusion
We could suggest that morphological differences in the middle ear morphology occur as a diffuse effect on bone turnover within
a temporal bone in patients with otosclerosis; however, due to the sample size limitation, we cannot exclude morphological
variations.Dostupno na: [https://eshnr.eu/wp_live_eshnr12_R4xCa/wp-content/uploads/ESHNR-2025-Glasgow-Abstract-Syllabus.pdf

Design and application of a two-part quadrangular device for fabrication of uniform test samples for bond strength testing between artificial tooth and denture base
No full textTo improve the precision and standardization of biomechanical testing of bond strength between artificial teeth
and denture bases, an innovative two-part quadrangular device was developed using 3D printing technology
(Bambu Lab X-1 Carbon) with polymeric materials. The development was based on a digital model of a
scanned artificial tooth (Atos Core 200), which served as a reference for producing uniform and reproducible
samples. The lower part of the device is designed for forming the denture base and is filled with wax, while the
upper part contains an opening with a specially designed guiding surface matching the dimensions of the
scanned tooth, enabling precise positioning at a 90° angle relative to the base. This ensures that each sample
is identical in orientation and dimensions, which is crucial for reducing variability in testing. The fabricated
samples then undergo a standard dental laboratory waxing procedure identical to the waxing phase of
removable denture models. This process ensures full compatibility with real clinical conditions of removable
denture fabrication, contributing to the validity and relevance of the obtained results. The unique design of the
device allows easy and safe removal of samples without damage, further increasing the reliability of
mechanical testing. The produced test samples are then tested on a universal testing machine using a device
for bond strength testing under variable loading angles, simulating the complex biomechanical conditions
present during functional mandibular movements. This innovative approach enables more precise evaluation
of adhesive properties between the tooth and denture base and represents a significant step forward in the
development and optimization of removable dental prostheses, with the potential to improve their longevity
and clinical reliability.Dostupno na: [http://cnntechno.com/docs/9_CNN_book_of_abstracts_fin.pdf
CORRELATION OF CLINICAL, RADIOLOGICAL, FNAC, AND HISTOPATHOLOGICAL FEATURES IN SALIVARY GLAND MASSES
No full textObjectives: To assess the clinical, radiological, and Fine needle aspiration cytology (FNAC) features
of salivary gland tumors and evaluate the risk of malignancy (ROM) for different cytological
categories using Milan Classification System compared to histopathological report as the gold
standard.
Methods: This retrospective study evaluates clinical, radiological, and FNAC findings, classified using
MILAN system, from patients clinically diagnosed with salivary gland tumors between 2020. and
February 2024.
Results: Among 75 patients (30 males, 45 females), 86.7% had benign and 13.3% malignant tumors.
The parotid gland was the most commonly affected. Warthin tumor and pleomorphic adenoma were
the most frequent benign tumors, while adenoid cystic carcinoma was the most common malignant
type. Statistically significant differences were observed regarding tumor consistency, mobility, and
peripheral facial nerve palsy (p<0.05). Of 55 available FNAC results, the prevalence with MILAN
categories was: Non-diagnostic (3.6%), Non-neoplastic (7.3%), Atypia of undetermined significance
(1.8%), Benign neoplasm (72.7%), Salivary gland neoplasm of uncertain malignant potential (3.6%),
Suspicious for malignancy (5.5%), and Malignant (5.5%). The corresponding risk of malignancy
(ROM) was 0%, 25%, 0%, 0%, 50%, 67%, and 100%, respectively.
Conclusions: Meticulous clinical and radiological assessment followed by FNAC are unavoidable
diagnostic steps for proper planning of the treatment of salivary gland tumors. Preoperative findings
are of paramount importance within the individualized and personalized medicine approach in the
treatment of salivary gland masses.Oral Presentation: OP 63Dostupno na: [https://e-bass.org/29thcongress/wp-content/uploads/2025/04/Abstract-Book-FINAL.pdf
