Lokalizacija glavnih i pomoćnih otvora na mezijalnom i distalnom korenu prvih donjih molara

Introduction. Understanding the morphology of the root canal system, and especially its apical third, represents the basic precondition for the successful treatment of diseased pulp and the apical endodontium. Aim. The aim of this study was to precisely locate the main and ancillary foramina in the mesial and distal first lower molars. Method. One hundred extracted first lower molars, originating from persons of both sexes and three different age groups, were used in the study. Results. The analysis of the sampled molars’ apical third was carried out using a binocular magnifier and a digital X-ray scanner (Trophy). The results showed that the main mesial and distal root foramina were located mostly on the distal surface. The ancillary mesial and distal root foramina were located at the lingual end, in most cases. Statistical analysis demonstrated the congruence of results achieved using the binocular magnifier and digital x-ray in 100% of cases if the main foramen is located on the very top of the mesial root (χ2 =17.23; p lt 0.001), and in 92.9% of cases if the main foramen is localised on the very top of the distal root of the first lower molar (χ2 =12.07; p lt 0.001). Conclusion. The most common localisation of the main foramina for all age categories and in both mesial and distal roots is on the distal surface of the root. The greatest number of ancillary foramina was observed in the youngest age category, while they were localised most often on the lingual side of the mesial and distal root.Uvod Poznavanje morfologije korenskog kanalskog sistema zuba, a naročito njegove apeksne trećine, predstavlja osnovni preduslov za uspešno lečenje obolele pulpe i apeksnog endodoncijuma.

Analysis of deformation and fragment breakage of rotary nickeltitanium instruments after preparation of different root canal systems

Savremena klinička endodoncija je težak i zahtevan mikrohiruški zahvat koji se sastoji se od niza postupaka, počev od formiranja kaviteta i pristupa kanalima pa sve do adekvatne trodimenzionalne opturacije očišćenog endodontskog prostora. Da bi bila uspešna, endodontska terapija mora zadovoljiti biološke i mehaničke ciljeve. Biološki aspekt se sprovodi adekvatnim debridmanom i dezinfekcijom unutrašnjeg endodontskog prostora, dok se mehanički ostvaruje preparacijom kanala u vidu konusa, uz maksimalno čuvanje originalne endodontske morfologije. Tokom poslednjih decenija, mašinska obrada kanala korena uz primenu nikltitanijumskih (NiTi) instrumenata, postala je standardna klinička procedura. Mašinski NiTi instrumenti, različitog dizajna i veličine, omogućili su lakšu i bržu instrumentaciju uklanjajući manju količinu dentina, uz značajno manju kanalnu transportaciju, bolju mogućnost centritanja duž kanala i bolju prilagođenost povijenosti kanala korena, posebno u apikalnoj zoni. Primena NiTi za izradu rotirajućih endodontskih instrumenata iskoristila je superelastična svojstva legure, njenu sposobnost povratka u prvobitni oblik (shape-memory effect), kao i visok stepen otpornosti na koroziju. Upotreba rotirajućih NiTi instrumenata u endodontskoj proceduri znatno olakšava i ubrzava njeno izvođenje, ali sa mogućnošću pojave proceduralnih greški (promena oblika kanala, formiranje stepenika i useka, transportacija, perforacija zida kanala, formiranje peščanog sata i fraktura instrumenta u kanalu). Fraktura NiTi instrumenta je najkompleksnija greška tokom mašinske instrumentacije. Za razliku od instrumenata od nerđajućeg čelika koji se vidno deformišu pre frakture, rotirajući NiTi instrumenti se vrlo često lome bez upozorenja i vidljivih znakova deformacije. Fraktura mašinskih NiTi instrumenata može nastati kao rezultat torzionog naprezanja, cikličnog zamora, ili kombinacijom ova dva faktora. Mogućnost frakture NiTi instrumenata svakako je povećana njihovom primenom u povijenim kanalskim sistemima ali i korišćenjem prekomerne sile tokom instrumentacije. Prisustvo iregularnosti površinske strukture i taloženje različitih naslaga na novim nekorišćenim instrumentima takođe može uticati na deformaciju i lom ovih instrumenata. Mogućnost deformacije ili čak loma instrumenata zavisi od brojnih različitih faktora: vrste materijala od kog su izrađeni instrumenti, anatomskih osobina kanala koji se obrađuju, dinamike i učestalosti primene instrumenata u kanalu, načina pripreme i sterilizacije, dizajna radnog dela instrumenta, kao i primene različitih hemijskih sredstava tokom instrumentacije. Svi ovi faktori su svakako i u bliskoj vezi sa manuelnom spretnošću i stručnošću terapeuta. Zalomljeni instrumenti su definitivno smetnja pri obradi, irigaciji i opturaciji kanala korena i mogu nepovoljno uticati na ishod endodontske terapije. Teškoće pri uklanjanu zalomljenih fragmenata mogu uzrokovati prekomerno uklanjanje dentina korena, što dodatno može oslabiti koren, ili čak dovesti do njegove perforacije. Posledice koje ova komplikacija uzrokuje, najčešći su razlog izbegavanja mašinske instrumentacije u endodontskoj proceduri. Imajući u vidu važnost predviđanja eventualnog loma NiTi rotirajućih turpija postavljen je osnovni CILJ istraživanja analize i provere površinskih i strukturnih promena, odnosno, nanostrukturnih karakteristika novih i NiTi rotirajućih instrumenata upotrebljenih u kanalskim sistemima različite povijenosti...Modern clinical endodontics is a difficult and demanding microsurgical procedure that consists of a series of procedures, ranging from cavity formation and access to the canals to adequate threedimensional obturation of the cleaned endodontic space. To be successful, endodontic therapy must meet biological and mechanical goals. The biological aspect is carried out by adequate debridement and disinfection of the internal endodontic space, while mechanically it is achieved by cone preparation, with maximum preservation of the original endodontic morphology. In past decades, rotary root canal treatment using nickel-titanium (Ni-Ti) instruments has become a standard clinical procedure. Rotary Ni-Ti instruments of different design and size, have made instrumentation easier and faster by removing less dentin, with significantly less canal transportation, better centering along the canal, and better adaptation to root canal curvature, especially in the apical zone. The use of Ni-Ti for the manufacture of rotary endodontic instruments utilizes the super-elastic properties of the alloy (shape-memory effect) as well as a high degree of corrosion resistance. The use of rotary Ni-Ti instruments in the endodontic procedure greatly facilitates and accelerates the performance, but with the possibility of procedural errors (change of canal shape, step and ledge formation, transportation, canal wall perforation, hourglass formation and instrument fracture in the canal). Ni-Ti instrument fracture is the most complex error during rotary instrumentation. Unlike stainless steel instruments that are visibly deformed before fracture, rotating Ni-Ti instruments often break without warning and visible signs of deformation. Fracture of rotary Ni-Ti instruments can result from torsional stress, cyclic fatigue, or a combination of these two factors. The possibility of fracture of Ni-Ti instruments is certainly increased by their application in curved canal systems but also by the use of excessive force during instrumentation. The presence of irregularities in the surface structure and the deposition of different deposits on new unused instruments can also influence the deformation and fracture of these instruments. The possibility of deformation or even fracture of instruments depends on a number of factors: the type of material from which the instruments are made, the anatomical properties of the canals being processed, the dynamics and frequency of application of the instruments in the canal, the method of preparation and sterilization, the design of the working part of the instrument, as well as the application of different chemical agents during instrumentation. All of these factors are certainly closely related to the therapist's manual dexterity and expertise. Broken instruments are a serious impediment to the treatment, irrigation, and obturation of the root canal and may adversely affect the outcome of endodontic therapy. Difficulties in removing broken fragments can cause excessive dentin removal of the root, which can further weaken the root, or even lead to its perforation. The consequences of this complication are the most common reason for avoiding rotary instrumentation in an endodontic procedure..

Debljina primarnog i sekundarnog dentina u predelu apeksnog otvora na mezijalnom i distalnom korenu prvog donjeg stalnog molara

Introduction Knowledge of the complexity of the root canal system in lower first molars and particularly the apical part of the root affects significantly the realization and success of the endodontic procedure. Aim The aim of this paper was to determine the thickness of the primary and secondary dentine around the main foramen of the mesial and distal root of the lower first permanent molar in teeth of various ages. Material and Method Fifty extracted lower first molars of both male and female patients extracted for various reasons were used in the study. All teeth were allocated to three age groups: under 25 years old (15 teeth), between 26 and 50 (20 teeth) and over 51 years old (15 teeth). After access cavity preparation, canal orifices were enlarged and root canals were explored using hand K-files #10. Using a diamond disc, the root tip was then cut off in the area of the apical foramen. Dentine thickness was determined using a complex configuration comprising of several devices which were interconnected by software. These included a polarised microscope (Leica DMLSP), a digital camera (Leica DC300) and a scanner. Results The results showed that the greatest mean thickness of the primary dentine was in the mesial root of the first lower molar in the first age group (0.177 mm), followed by the third (0.145 mm) whilst the least mean thickness was observed in the second age group (0.141 mm). In the distal root, the mean thickness of the primary dentine was in the second (0.175 mm), then the first (0.138 mm) and finally the third group (0.100 mm). The mean thickness of the secondary dentine in the mesial root was observed in the second group (1.25 mm), followed by the third (1.11 mm) whilst the least mean thickness was found in the first age group (0.95 mm). The mean thickness of the secondary dentine in the distal root was observed in the second group (1.26 mm), then the third (1.18 mm) whilst the least mean thickness was found in the first age group (0.99 mm). Conclusion The obtained results suggested that the mean thickness of the primary dentine in the mesial and distal roots was comparable. For both mesial and distal roots, the greatest mean thickness of the secondary dentine was observed in the second age group.Uvod Poznavanje kompleksnosti kanalskog sistema prvih donjih molara, posebno apeksnog dela korena zuba, značajno utiče na pravilnu realizaciju i uspeh endodontskog lečenja. Cilj rada Cilj rada je bio da se kod zuba različitih starosnih kategorija odredi debljina primarnog i sekundarnog dentina oko glavnog otvora kanala na mezijalnom i distalnom korenu prvih donjih stalnih molara. Materijal i metode rada Kao materijal u istraživanju korišćeno je 50 prvih donjih molara osoba oba pola ekstrahovanih zbog različitih indikacija. Svi zubi su, prema starosti, svrstani u tri kategorije: uzorci do 25 godina starosti (15 zuba), uzorci stari 26-50 godina (20 zuba) i uzorci stariji od 50 godina (15 zuba). Nakon formiranja pristupnog kaviteta, ulazi u kanale korena su levkasto prošireni i urađena je eksploracija kanala ručnim instrumentima tipa K10. Potom je pomoću dijamantskog diska odsečen vrh korena do mesta otvora kanala na korenu. Analiza debljine dentina oko glavnog otvora urađena je pomoću kompleksne konfiguracije nekoliko uređaja koji su međusobno bili softverski povezani. To su polarizacioni mikroskop (Leica DMLSP), digitalna kamera (Leica DC300) i skener. Rezultati Najveća prosečna debljina primarnog dentina na mezijalnom korenu prvog donjeg molara uočena je u prvoj grupi - 0,177 mm; u trećoj je bila 0,145 mm, dok je najmanja prosečna debljina zabeležena u drugoj grupi - 0,141 mm. Najveća prosečna debljina primarnog dentina na distalnom korenu zabeležena je u drugoj grupi - 0,175 mm; u prvoj je bila 0,138 mm, dok je najmanja prosečna debljina dentina uočena u trećoj grupi - 0,100 mm. Najveća prosečna debljina sekundarnog dentina na mezijalnom korenu prvog donjeg molara ustanovljena je u drugoj grupi - 1,25 mm; u trećoj je bila 1,11 mm, dok je najmanja prosečna debljina zabeležena u prvoj grupi - 0,95 mm. Najveća prosečna debljina sekundarnog dentina na distalnom korenu prvog donjeg molara uočena je u drugoj grupi - 1,26 mm; u trećoj je bila 1,18 mm, dok je najmanja zabeležena u prvoj grupi - 0,99 mm. Zaključak Rezultati su pokazali da je prosečna debljina primarnog dentina na mezijalnom i distalnom korenu bila približno jednaka. Prosečna debljina sekundarnog dentina bila je najveća na mezijalnom korenu zuba starih između 26 i 50 godina. Najveća prosečna debljina sekundarnog dentina uočena je na distalnom korenu takođe u ovoj grupi

Primena različitih sistema za fiksiranje protetičkih rešenja na implantatima - prikaz slučaja

Implantology has become an important therapeutic procedure that allows complete aesthetic and functional rehabilitation of the oro-facial system in edentulous patients. Implant supported prosthetic restorations can be fixed in two ways, by cement or screws. Both techniques have advantages and disadvantages and their selection depend on situation in patient’s mouth. The aim of this study was to describe complete process of prosthetic rehabilitation in an edentulous patient, from pre-implant preparation, through implant placement and fixation of final restoration on implants. In this case report, one ceramo-metal bridge was fixed by screws in the lower jaw while the other one was fixed using glass-ionomer cement in the upper jaw. After bone augmentation and time necessary for its osseointegration (6 to 8 months), 16 implants were placed in both jaws. Eight weeks after the implant placement, final prosthetic rehabilitation was achieved by cementation of one ceramo-metal bridge in the upper jaw using glass ionomer cement and fixation of the second bridge with screws in the lower jaw. To achieve successful implant supported prosthetic rehabilitation, the treatment protocol must be followed from the beginning to the end of the therapy.Ugradnja implantata je danas vrlo važna terapijska procedura u stomatološkom zbrinjavanju pacijenata bez zuba zbog mogućnosti potpune estetske i funkcionalne rehabilitacije orofacijalnog sistema. Protetičku restauraciju na ugrađenim implantatima moguće je fiksirati na dva načina: cementiranjem ili pomoću šrafova. Obe tehnike imaju prednosti i mane, a njihov izbor zavisi od stanja u ustima pacijenta. Cilj ovog rada bio da se prikaže celokupan postupak zbrinjavanja pacijenta bez zuba, počev od preimplantološke pripreme, preko ugradnje implantata, do fiksiranja završenog protetičkog rada na implantatima. Kod pacijenta je u donjoj vilici postavljen metalokeramički most na osnovi fiksiranoj šrafom, dok je u gornjoj vilici most fiksiran glasjonomer-cementom. Nakon ugradnje veštačke kosti i vremena neophodnog za njenu oseointegraciju (od šest do osam meseci), postavljeno je 16 implantata u gornjoj i donjoj vilici. Osam nedelja od ugradnje implantata urađena je konačna protetička rehabilitacija pacijenta, koja je završena cementiranjem jednog metalokeramičkog mosta u gornjoj vilici glasjonomer-cementom, te fiksiranjem drugog mosta pomoću šrafova u donjoj vilici. Da bi se postigla uspešna protetička rehabilitacija pacijenta pomoću implantata, potrebno je pridržavati se protokola od početka do kraja terapije

Dental status of institutionalized persons with special needs who live in Special institution “Srce u jabuci” in Pancevo

Introduction. Dental status of most people with special needs is not satisfactory. Many of them are edentulous or toothless, with acute extensive caries lesions present, high DMFT index and severe periodontal disease. The objective of this study was to examine the dental status of mentally impaired persons who live in the special institution “Srce u jabuci” in Pancevo. Material and Methods. Clinical examination was performed on 114 institutionalized patients (68 male and 46 female), age 22 to 71 years. Patients were divided in two groups; the first group consisted of 71 persons who had a moderate mental disorder (F71), while the second group included 43 respondents with severe mental retardation (F72). Oral examination revealed: the number of present teeth, caries lesions, the presence of restorations, the number of extracted teeth, the presence of residual roots, fractures and the presence and number of fixed restorations. Results. The mean DMFT of total examined teeth was 20.33±7.63. The greatest percentage found for extracted teeth (63.76%): in the first group 63.23%, and in the second 64.06%. The percentage of teeth that had caries lesions of all examined teeth was 33.48%, while the lowest percentage was for restored teeth (2.76%). In majority of examined people, initial caries, deep caries, or tooth with the exposed pulp (K1 - 51.74% K2 - 40.35%, K3 - 51.75%) were not found. A high percentage of examined people had more than 10 extracted teeth (52.63%). Most of them did not have any restoration in the mouth (81%) and only three persons had fixed denture. Conclusion. Dental status of institutionalized mentally impaired persons showed high prevalence of extracted teeth, significant presence of carious lesions and small percentage of restored teeth with inadequate oral hygiene

Udaljenost glavnih i pomoćnih otvora od vrha mezijalnog i distalnog korena prvog donjeg stalnog molara

The main prerequisite for a successful treatment of pulp disease in apex periodontium is knowledge of morphological characteristics of root canal system, especially one third of his apex. The aim of this work was to define the exact distance of the main and auxiliary openings from the top of medial and distal roots of the first lower permanent molars. Methods: as a research material it was used a hundred extracted first lower molars of the patients of both gender, divided into three age groups. The analysis of the one third of apex was done with the help of binocular magnifying glass and digital roentgenography analysis half of the samples, which were filed with capillary contrast. Results: The results obtained showed that the longest average distance of the main opening from the top of medial root was 0.84mm, and the shortest was 0.61mm; while for the distal root the longest average distance was 0.89mm, and the shortest was 0.62mm. Maximum distance of the auxiliary openings from the top of medial root in the first group was 3.5mm, and the maximum distance of the auxiliary openings from the top of distal root was 2, 5 mm. The results obtained with digital rentgenography showed that the longest average distance of the main opening from the top of medial root was the one noticed in the second age group (0.91mm) then the one from the first group (0,83), and the shortest one in the third age group (0,71mm); as for the distal root: the longest average distance of the main opening from the top of the root was noticed in the third age group (0,95mm) then in the first (0,90mm) and than shortest in the second age group (0,89mm). Conclusion: The distance of the main and auxiliary openings from the top of medial and distal root of the first lower molar varies in the range from 0 to 3,5mm and it depends on the tooth age.Poznavanje morfoloških karakteristika korenskog kanalskog sistema, a posebno njegove apeksne trećine, predstavlja osnovni preduslov za uspešno lečenje obolele pulpe i apeksnog parondodoncijuma.

Maksimalna udaljenost pomoćnih otvora od vrha mezijalnog korena u prvoj grupi je iznosila 3,5mm,a maksimalna udaljenost pomoćnih otvora od vrha distalnog korena je iznosila 2,5mm. Rezultati dobijeni digitalnom rengenografijom ukazuju da je najveća prosečna udaljenost glavnog otvora od vrha mezijalnog korena uočena u drugoj starosnoj grupi (0,91mm) potom u prvoj ( 0,83 mm) i najmanja u trećoj starosnoj grupi (0,71mm); dok je za distalni koren najveća prosečna udaljenost glavnog otvora od vrha korena uočena u trećoj starosnoj grupi (0,95mm) potom u prvoj (0,90 mm) i najmanja u drugoj starosnoj grupi ( 0,89mm). Zaključak. Udaljenost glavnih i pomoćnih otvora od vrha mezijalnog i distalnog korena korena prvog donjeg molara varira u opsegu od 0 do 3,5mm i u zavisnosti je od starosne kategorije zuba

Endodontska terapija donjeg molara kod pacijenta sa parestezijom donjeg alveolarnog nerva – prikaz slučaja

Root canal (endodontic) treatment is demanding and complex procedure. A variety of difficulties can occur in different phases of endodontic procedure. Complex anatomorphological tooth structure, curved canals, close proximity of lower molars and premolars to inferior alveolar nerve make endodontic treatment even more challenging. During endodontic treatment, an inferior alveolar nerve may become traumatized and symptoms may vary from mild neurosensory dysfunction to a complete loss of sensation in the innervation area of damaged nerve. The aim of this paper is to present a clinical case of endodontic treatment of lower second molar with C-shaped root canal in a patient with paraesthesia of inferior alveolar nerve due to endodontic origin.Endodontska terapija kanala korena zuba je težak i kompleksan zahvat, pa su zato česti i problemi u različitim fazama endodontskog postupka. Komplikovana anatomomorfološka struktura zuba, povijenost kanala, blizak odnos donjih molara i premolara i alveolarnog nerva dodatno komplikuje endodontsku proceduru. Tokom realizacije endodontske terapije može doći do traume donjeg alveolarnog nerva, a simptomi oštećenja alveolarnog nerva mogu da variraju od blage neurosenzorne disfunkcije do potpunog gubitka senzacija u predelu inervacionog područja oštećenog nerva. Cilj ovog rada je bio da se na jednom slučaju iz kliničke prakse predstavi endodontski postupak lečenja kanala korena donjeg drugog molara, karakterističnog c-oblika, kod pacijenta sa parestezijom donjeg alveolarnog nerva endodontskog porekla
