Introduction: Non-carious tooth substances loss pose a major health problem of a modern man. The literature often collectively describes all non-carious lesions and is therefore difficult to compare results obtained by different authors. Chemical factors are one of the predisposing factors responsible for the formation of wedge-shaped erosions. Aim: Examination of chemical risk factors as one of the predisposing causes responsible for the formation of wedge-shaped lesions. Method: We examined 62 patients with wedge-shaped erosions (mean age 45.52 ± 12.03 years, 58.1% of men) and 60 patients without erosions in the control group (mean age 34.40 ± 9.28 years, 60% men) . The entire examination was completed by using a questionnaire at the Dental Clinic of the University of Pristina - Kosovska Mitrovica. salivary pH was measured by the pH meter. Results: The results show that the wedge-shaped lesions often occur equally in both men and women. Considerably often it might appear in older people but can also occur in teenagers. Patients with wedge-shaped erosion have increased acidity of saliva, a heightened sense of acid in the mouth and consume a lot more carbonated drinks compared to patients without erosions. Conclusion: Wedge-shaped lesions are more common in people older than 40 years. Taking into account the results obtained in this study it can be concluded that the chemical risk factors truly fall within the predisposing factors that may be responsible for the creation of wedge-shaped erosions.

The mos Tooth whitening is a procedure that removes stains and various discolorations of tooth surface. Discoloration of teeth may be endogenous and exogenous nature. The aim of this study was to investigate the impact of bleaching combined with daily use of drinks that cause tooth discoloration. Evaluated the changes in surface structure of enamel, and changes in hardness after bleaching. Were 20 extracted teeth. The teeth are marked with longitudinal lines halves (medial vestibular and distal surfaces). Tretitana mesial half of the 16% carbamide peroxide, a distal was left as control. NDT device HL400DL, duroskopskom method of enamel hardness was measured before treatment, after treatment and after remineralization. Olympus inverted microscope GX41 enamel structures were observed in the treated and control half of the tooth. After bleaching there is a difference compared to the untreated surface, that surface is bleached a few shades lighter, but after the use of coffee and soft drinks teeth back to the original dark color. Enamel microhardness after the treatment is somewhat small but not significant. With a magnification of 2000x and see the structural changes in enamel. Tooth whitening, but that the remineralization and the abstinence from prebojenih beverages and tobacco.

Suštinu biološkog lečenja caries profunda čini proces 'ozdravljenja' koji se zasniva na stimulaciji dentinogenetske funkcije pulpe, što omogućava stvaranje mineralizovanog tkiva. U eksperimentalnom istraživanju postavljen je cilj da se skening elektronskom mikroskopijom i polarizacionom mikroskopijom: Analiziraju promene na celularnim i ekstracelularnim komponentama zubne pulpe posle direktnog i indirektnog prekrivanja alkalnim cementom (Dycal), Utvrdi izgled dentinske površine posle direktnog i indirektnog prekrivanja pulpe i Formira predlog za kliničku primenu preparata Dycal ukoliko obezbeđuje dobru i efikasnu dentinogenezu. Ispitivanje je izvršeno na eksperimentalnim životinjama (domaća svinja). Za ovo istraživanje korišćen je alkalni cement Dycal. Na zubima eksperimentalne grupe uradjene su preparacije V klase sa vestibularne strane. Na jedanaest zuba je uradjeno indirektno, a na jedanaest zuba direktno prekrivanje pulpe. Nakon završene preparacije dentin je direktno prekriven alkalnim cementom Dycal. Preko Dycal-a je postavljena podloga cink fosfatnog cementa i materijal za definitivno zatvaranje kaviteta (amalgam). Na zubima gde je urađena perforacija komore pulpe Dycal je ubacivan direktno u komoru pulpe, a preko toga je postavljena podloga cink fosfatnog cementa i kavitet je definitivno zatvaran amalgamom. Adekvatno pripremljeni zubi i pulpa posmatrani su SEM i polarizacionim mikroskopom. Rezultati: Posmatranjem i analizom dobijenih rezultata, na polarizacionom i skening elektronskom mikroskopu u poređenju sa kontrolnom grupom, dobijeni su rezultati koji mogu imati značajnu kliničku implikaciju u biološkom lečenju pulpe. Dycal direktno apliciran u komoru pulpe: uočava se granica između novostvorenog reparativnog dentina u normalnu dentinsku strukturu, sreću se degradirane smežurane ćelije, zapažaju se jezgra kalcifikacije, mladi krvni sudovi i ćelije (fibrociti, histiociti i fibroblasti). Indirektno aplikovan Dycal: uočava se normalna dentinska struktura , jasno su vidljivi dentinski kanalići, a sreće se i atubulusna dentinska struktura, vidi se slika dentinske strukture koja prožima acelularno pulpno tkivo, hipercelularnost na granici stvaranja novog dentina i brojni krvni sudovi. Prisustvo amorfnog kalcifikata dentinske strukture govori o početnom stvaranju barijere od čvrstog tkiva što je cilj eksperimenta. Dobijeni rezultati eksperimentalnim istraživanjem sugerišu Dycal kao dobar materijal za direktno i indirektno prekrivanje pulpe.

Telemedicina je kao sistem pružanja zdravstvene zaštite, definisana od Svetske zdravstvene organizacije (SZO) kao praktična zdravstvena zaštita koja koristi interaktivnu zvučnu, vizuelnu komunikaciju i razmenu podataka. Univerzitetski telemedicinski centar u Kosovskoj Mitrovici obezbeđuje stalnu dostupnost kadra neophodnih specijalnosti za brzu i efikasnu telekonsultaciju u slučajevima kada je ona neophodna ili se nameće kao metoda izbora u pomoći kod postavljanja dijagnoze, ali i planiranja i sprovođenja same terapije. Prikazana je 'store and forward' telemedicinska konsultacija u vidu slučaja normalnog nivoa hitnosti koji je zahtevao interdisciplinarni pristup između stomatologa endodonta i stomatologa oralnog hirurga. Kao pametna veza između telekonsultanata pri Univerzitetskom telemedicinskom centru korišćen je XPA3 online aplikacioni sistem. Nakon adekvatne telekonsultacije u kojoj su učestvovali lekari iz Kosovske Mitrovice, Niša i Podgorice, na pacijentu je uspešno sprovedena endodontsko oralnohirurška terapija, čime je pacijent u potpunosti zbrinut.

There are different stick types and shapes, different root canal preparation techniques, as well as different materials for stick cementing and making annexes around posts. The use of fiber-reinforced resin posts to restore endodontically treated teeth has gained popularity due to its mechanical and esthetic characteristics as well as properties of modern adhesive systems. The aim of this article was to show a clinical technique to reconstruct endodontically treated teeth with great loss of tooth structure using direct fiber-reinforced post systems and direct composite restorations. After the preparation of the root canal and cementation of a FRR post, particular attention was paid to the incremental and curing techniques adopted to reconstruct coronal part of the tooth. It is possible to place of fiber-reinforced resin posts. 

Materials wich use like base,and those used for direct and indirect capping should be, except certain physicalchemical and biological performance have and antibacterial effect, to act after the application on residual microorganisms. The aim of this study is that in vitro display antimicrobial activity of some selected resources that are used to protect the dentin below the permanent restoration, and some of this as medication in treating deep surface carious lesions and to directly cover any caries, either artificially open pulp. Antimicrobial activity was tested against microorganisms. On agar plates into the grooves 4 mm in diameter was inserted freshly prepared paste or base. After inserting the material into the surface of bloî od agar, was performed by incubation under aerobic conditions for 24 h in a thermostat at 37 C. Negative effect on the microorganisms, tested materials, it was estimated by the size of growth inhibition zone.

Vital extirpation is microsurgical intervention.Wellknowing of internal morpfology of pulp cavity and with patience, carefull and precise work is possible to extirpate, dilatate and fil in both distal and mesial root of down molars,even if in mesial root exists two canal (buccal and lingual) what is the ruosh aften finding. Vital extirpation is very frequenthy used method in the treatment of multi-root teeth.It is more requested intervention tlak usnal once,but patients mane less visits at the dentist and the results one good enongh. So, one session method isacceptable as from medical point of view but endodontic too.

Treatment, rehabilitation and aesthetics should be the main tasks of modern dentistry. Adequate prosthetic therapy and rehabilitation may be conditioned by different factors. The paper describes prosthetic rehabilitation of a patient, 55 years old woman, with abnormalities in the vertical dimension of occlusion and malocclusion of the third class, and all in order to return of aesthetics and the function of stomatognathic system. The patient came to the clinic due to disturbed aesthetics and function, where was achieved the appropriate amount of bite along with satisfactory aesthetics and functional results due to a combination of fixed and partial dentures. Two metal-ceramic bridges consisted of 13 pieces were built in the upper jaw, and 8 teeth mobile partial denture in lower jaw, thus resulting in satisfactory requirements set to re-establish aesthetics and function of stomatognathic system. 

The nature of herpes simplex virus as infective agens, which can grow in number, only in live cells, and fact that many herpes virus infections of oral tissue have atypic and asymptomatic course, makes their diagnosis more difficult and complicate from infections caused by other microorganisms. The aim of this investigation were to established cytological findings oral lesions of primary and recurrent herpes infections.

After restoration of approximative cavities where gingive wall is forming subgingivaly occurs an damage of epitel of gingival sulcus and subepitel fibrous tissue. These damages occur partially in order of direct irritative effect of materials, and partially because of inadequately made definite reisen. Anomaly which may occur while making reisen, is effect of micro leakage between reisen wall of cavities roughness and reisen parts which prominate above anatomic tooth sphere , enable faster and bigger accumulating of dental plaque. Gingive inflammation is widening deeper in parodontium trough vascular network situated in interdental bone septum. Inflammation is constantly spreading from the point and reaches parodontium. The aim of this study is to estimate clinical changes in parodontium within certain group of patients of different age and sex, caused by inadequate dental restoration. Results of this research present that anomaly in dental reisen , have great influence on inflammation reaction of parodontium. Composite reisen cause higher degree of inflammatory reaction in compared to amalgam reisen
