   Abstract:	The purpose of this case report is to present a bone defect restoration after radicular cyst enucleation using guided bone regeneration procedure with immediate implant insertions. The patient was a 50-year old female with an odontogenic cyst of the first premolar in the right maxilla and a second molar root resorption caused by an impacted third molar. The surgical procedure involved a cyst enucleation followed by guided bone regeneration, immediate implantations, and surgical removal of the impacted third molar. The patient was supplied with an interim partial denture during the osseointegration period. Six months after surgical treatment, the implant stability was assessed by resonance frequency analysis. Mean scores for the first premolar and first molar implants were 74 and 78, respectively. Both implants were monitored clinically and radiographically during the following 6-month period. Implant stability was considered adequate. Neither clinical nor radiological complications were present throughout the postoperative 6-month period. The implants were used to support a fixed partial denture. Immediate implantations after odontogenic cyst enucleation minimized the number of surgical procedures and led to a satisfactory result.

   MeSH:	TOOTH EXTRACTION DENTAL CARIES
   Abstract:	Svrha rada bila je istražiti i ustanoviti primarne razloge za ekstrakciju zuba u trajnoj denticiji. Materijali i postupci: Istraživanje smo organizirali od siječnja do ožujka 2007. na Stomatološkom fakultetu u Zagrebu, u Zavodu za endodonciju i restaurativnu stomatologiju i Zavodu za oralnu kirurgiju. Kao metodu odabrali smo upitnik koji je, osim osobnih podataka pacijenta, sadržavao i osnovne razloge za ekstrakciju. Prikupljene podatke statistički smo obradili parametrijskom i neparametrijskom analizom varijance, ovisno o distribucijama dobivenih podataka. Rezultati: Ukupno je bilo anketirano 113 ispitanika u dobi od 10 do 85 godina - 61 (54%) žena i 52 (46%) muškarca. S obzirom na to koliko su često odlazili stomatologu, više je bilo neredovitih pacijenata (54,9%). U svim dobnim skupinama najčešći razlog za ekstrakciju bio je karijes (53,4%), a kod većine pacijenata (75,7%) prije toga nije bila provedena nikakva endodontska terapija. Najčešće ekstrahirani zubi bili su prvi trajni molari zbog karijesa (25,3%), a donji frontalni bili su uglavnom izvađeni zbog parodontopatija i to u dobnim skupinama iznad 45 godina (8,7%), a kod mlađih bili su ekstrahirani prvi premolari uglavnom iz ortodontskih razloga. Zaključak: Zbog opsežnih karioznih destrukcija molara nije bilo moguće obaviti adekvatnu endodontsku i/ili konzervativnu terapiju, pa je ekstrakcija bila jedina terapijska mogućnost. Zbog toga se mora više truda uložiti u preventivne programe kako bi se sačuvalo oralno zdravlje.

   MeSH:	DENTAL IMPLANTATION ESTHETICS, DENTAL MINIMALLY INVASIVE SURGICAL PROCEDURES
   Abstract:	The current trend in dental implantology is to develop techniques that can provide function, esthetics, and comfort with a minimally invasive surgical approach. Minimally invasive one-stage flapless technique in maxillary anterior region is usually considered in conjunction with functional or non-functional immediate loading. In this report, a clinical case of using minimally invasive one-stage flapless technique for maxillary right incisor replacement with immediate non-functional loading is presented. A patient was a 21-year-old male with clinical and x-ray signs of a vertical fracture of the endodontically treated maxillary right incisor. After the tooth extraction, guided bone regeneration procedure was performed to prevent post extraction alveolus collapse and provide a better site for the future implant. After 4 months transmucosal surgical approach was used to insert a tapered implant. Location was determined on the basis of slice ortopantomogram x-rays and surgical drill guide was made for precise definition of implant site and angulation. The implant was immediately restored with final zirconium oxide ceramic abutment and temporary acrylic crown without any occlusal contacts. After a healing period of 6 months, the osseointegration was assessed with resonance frequency analysis (value 75.3) and considered adequate. The implant was then treated with the final fixed prosthetic restoration. The patient exhibited neither clinical nor radiologic complications throughout the 6 months period of clinical monitoring.

   MeSH:	MOUTH NEOPLASMS LYMPHOMA, NON-HODGKIN
   Abstract:	Malignant lymphoma of the oral region are uncommon and account for approximately 3.5% of all oral malignancies. In this report, a case of primary non-Hodgkin lymphoma of the left mandible is presented. The spontaneous and intermittent pain of the left mandible had continued after third left molar extraction. Intraoral examination revealed healing retardation of the postextraction socket. A panoramic radiograph revealed a radiolucency in the posterior mandibular region with irregular margins. After the 10-day course of antibiotics the spontaneous pain diminished, but the inadequacy of the healing at the extraction site was still present. We initially misdiagnosed it as chronic osteomyelitis. Based on the histological and immunohistochemical examination, we made the diagnosis of diffused large cell lymphoma of the B-cell type. After the combination of chemotherapy and radiotherapy patient showed complete remission with the disappearance of all clinical evidence of disease. The diagnosis of extranodal lymphoma of the jaw may be chalenging, because frequently there is a low index of clinical suspicion and malignant tumor may mimic common oral and dental pathological conditions. Dentists can play the important rule in the early detection of the malignant lymphoma of the oral cavity.

   MeSH:	ALVEOLAR RIDGE AUGMENTATION MAXILLARY SINUS ORAL SURGICAL PROCEDURES
   Abstract:	Distal edentulousness of the maxilla, together with extensive resorption of the alveolar crest or high pneumatization of the maxillary sinus, is often a limiting factor for implant-prosthetic rehabilitation. It is possible to compensate insufficient bone volume by elevating the floor of the maxillary sinus using an operative procedure (sinus floor elevation or sinus lifting). Elevation of the sinus floor is an operative procedure based on moving the bottom of the sinus cranially while simultaneously augmenting the bone defect, with the purpose of creating sufficient height at the bone fundament needed for the placement of dental implants. This operative technique has been routine in clinical practice since 1986 and is constantly being improved and modified. The purpose of this review is to present the different techniques in sinus lifting with all their advantages and disadvantages in order to render their implementation in clinical practice as successful as possible. Elevating the maxillary sinus floor by augmentation with allograft or autologous bone implants is a reliable method which broadens the indications for the placement of dental implants in the molar region of alveolar bone A, where, due to extensive pneumatization of the maxillary sinus, it was not previously possible.

   MeSH:	DENTAL IMPLANTATION + methods COMPOSITE RESINS
   Abstract:	Fibre reinforced composites (FRC) are a specific group of materials consisting of composites in which determined types of fibre are inserted. The fibres differ according to their chemical composition and method of construction. With regard to the chemical composition, polyethylene and glass fibres are most frequently used today in restorative and aesthetic dentistry (apart from these two types, carbon and kevlar fibre can be found). According to the method of construction the fibres can be parallel or plaited. Plaited fibres differ mutually with regard to the size and method of plaiting. In the last few years application of fibres in daily clinical work has become increasingly important. Their application has been found in almost all areas of the dental profession: periodontology, restorative dental medicine, traumatology, orthodontics, etc. The fibres can be constructed in two basic forms: impregnated and unimpregnated. Impregnated fibres are packed in a special way and already coated with the composite base, while in the case of unimpregnated fibres prior preparation is necessary before insertion in the composite material. The application of fibre reinforced composites has opened up new possibilities in the treatment of specific problems which can occur during implantological-prosthetic therapy. The purpose of the lecture is to show the possibilities of the application of fibre reinforced composites in different clinical cases and to describe possible errors during clinical construction.

   Title in Croatian:	Komplikacije i neuspjesi u dentalnoj implantologiji
   Type of Article:	congress abstract
   MeSH:	DENTAL IMPLANTATION + adverse effects
   Abstract:	The increasing use of dental implants in everyday dental practice, and the systematic and documented years of monitoring patients with implanted and prosthetically supplied dental implants, leads to frequent confrontations of the therapist with different kinds of complications, and also failures. Although complications and failures are not the same, they are closely connected in dental implantology. However, not every complication necessarily leads to failure. Thus every therapist must be capable of envisaging possible complications, and eventually prevent them in time, or if they arise to know how to treat them. Complications in dental implantology can be divided into surgical and prosthetic complications. Surgical complications can be intraoperative, early postoperative and late postoperative complications, of which the most frequent are periimplant changes/lesions. Prosthetic complications are usually connected with unsatisfactory direction and localisation of the implant, instability and fracture of elements of the reinforcement, fracture of bridge constructions, aesthetic and functional complications and loss of the implant. In the broadest sense failure in dental implantology is clearly loss of the implant due to any reason, but also dissatisfaction of the patient with the functional or aesthetic effect also leads to failure. The paper presents our experience to date with complications, and also failures, during the use of different types of implantological systems.

   Type of Article:	congress abstract
   MeSH:	JAW, EDENTULOUS + therapy REHABILITATION DENTAL IMPLANTATION
   Abstract:	Immediate placement of an implant in the fresh alveoli of an extracted tooth has many advantages compared to delayed implantation. In the first place the shortened period of implant prosthetic rehabilitation of approximately 6-8 months, which is the time necessary for the alveoli to fill with the newly formed bone, the smaller number of surgical interventions, prevention of bone resorption and better positioning of the implant. Histomorphometrical analyses on an experimental model have demonstrated that healing of the bone defect around the immediately placed implant in post-extraction alveoli is complete and that the possibility of osseointegration better than in the case of delayed implantation. The reason is the greater potential for healing fresh extractive alveoli. Schultes’s investigation showed that the percentage of osseointegrated surface 6 months after immedi-ate placement of implants was 80%, compared with delayed implantation where this percentage was somewhat less, 75%. An example is given of a female patient, aged 56 years, with distal partial edentulousness/edentia of the left side of the upper jaw. Complete implantoprosthetic rehabilitation was achieved by a combination of two different types of implants and the technique of immediate implantation of a conical, screw implant into the fresh alveoli of an extracted left upper canine. An example will also be given of immediate implantation with augmentation of the bone defect by autologous bone transplant in the case of loss of one tooth in the frontal region and an example of immediate implantation on the site of extracted lower canines, with anchors of the lower supporting prostheses.

   MeSH:	ABSCESS
   Abstract:	The aim of this study was to show the importance of a detailed clinical examination, diagnostic analysis and good knowledge of the pathology of the oral cavity, in order to avoid erroneous treatment and loss of precious time.The first patient, R. J., a 36-year-old man, was admitted to the ENT Department of the General Hospital, Karlovac, because of a perimandibular swelling and trismuss of the right side of the face. Because an odontogenic abscess was suspected extraoral incision was performed on two occasions. After the arrival of an oral surgeon to the hospital and examination of the oral cavity the patient was transferred to the Clinical Department of Oral and Maxillofacial Surgery, University Hospital Dubrava. During an intraoral examination an ulcer was detected beneath the tongue on the right side and a massive infiltrate of almost the whole of the anterior two thirds of the tongue. Immovable metastasis was detected by palpation in regions two and three, 50 millimetres in size. After consultation at an oncological Meeting irradiation only was indicated. A check-up six months later showed partial regression of the disease.The second patient, K. J., a 33 year-old man, came to the Out-patient Department of Oral Surgery with suspected palatinal abscess of the upper left molar. The upper left six was trepanated and the suspect abscess incidirated twice. For a period of six months no regression occurred and consequently the patient was sent to the Clinical Department of Oral and Maxillofacial Surgery, University Hospital Dubrava, where cytopuncture, biopsy, CT of the maxilla were performed which confirmed mucoepidermoid carcinoma of the hard palate. After preoperative preparation partial resection of the upper jaw was performed. Therapy is presently in course.These two cases indicate the need to know the causative agents of swellings in the area of the head and neck, and if odontogenic inflammation is the case it quickly responds to appropriate therapy.

    Abstract:	A case of a patient with osteoma of the lower jaw is presented. Osteoma caused compression of the mental nerve and neuralgiform pain. During an intraoral examination, osseous deformity of the mandibula was not found. Diagnosis was confirmed by X-ray, which showed enostosis or a central osteoma. The presentation describes the surgical technique of external decompression by which the nerve epineural integument is released from the pressure caused by the benign osseous formation. Six months after the surgery the patient had no symptoms and had normal sensibility in the lower jaw and no irregularities.

    Abstract:	The aim of this study was to determine the appearance of odontogenic keratocysts (OKC) and keratocyst-like lesions ( KLL) in patients with Gorlin-Goltz syndrome, according to age and gender of participants, and in relation to the place of origin (mandible, maxilla, soft tissues, which include the mucosa of the alveolar ridge, skin of the nose and face, parotid gland together with maxillary sinuses). From 1965 until 1998, 58 OKC were found in 30 patients with Gorlin Goltz syndrome and confirmed by histopathologic analysis. Patients were aged from 10 to 90 years. Average age of the patients with Gorlin-Goltz syndrome was 33.71 years. Average age in males was 35.53 years and in females 31.12 years. OKC connected with Gorlin Goltz syndrome were more frequently found in males (58.62%) compared to the females (41.38%). The peak incidence of OKC in patients with Gorlin-Goltz syndrome was between ages 21-30 years. According to the location, OKC were found predominantly in the mandible (60.34%), the maxilla (15.52%), soft tissues (13.79%), and in maxillary sinuses (10.34%).

    MeSH:	DRY SOCKET FACIAL PAIN + etiology
    Abstract:	Postextraction pain or alveolitis sicca dolorosa is a complication which appears after tooth extraction, usually in the molar region of the lower jaw. In this paper two methods were compared: conservative and surgical-conservative method. The research was carried in order to establish which method is more advantageous and more effective. The pain treatment lasted for one year. Thirty patients were treated and each of them were separately conducted during three weeks after the treatment. Fifteen patients were submitted to conservative therapy, and fifteen others to surgical-conservative therapy. The results (tables and charts) show that both methods are effective and that both methods lead to symptom termination. However, surgical- conservative method appeared to be more effective, because inthe first seven days after the therapy, approximately 75% of the patients no longer had alveolitis symptoms.

    Abstract:	The aim of the study was to evaluate the sealing quality of mineral threeoxide aggregate (MTA), Super EBA and IRM cement in an ultrasonically prepared cavity using a dye penetrating technique. The experiment was carried out on 35 single rooted permanent teeth. Their roots were treated by a conventional “step back” technique and filled by a cool lateral condensation technique. After hardening in a physiological solution, root-ends were resectioned and a retrograde cavity 1.5 mm in diameter, 3 mm deep was prepared by an ultrasonic tip. MTA, Super EBA, IRM, filled ten samples and a control group of 5 samples were filled by amalgam. A dye was added to the samples, which were left in a testing rood. After reaching tooth transparency, results were noted by a stereomicroscope with the use of a calibrated scale on the ocular. Statistical results indicated that samples filled with MTA had least leakage in comparison to those filled with IRM and Super EBA cement.

    Abstract:	The aim of the study was to explain in detail the usage of KaVo DIAGNOdent 2095 and to determine its advantages in clinical detection of early demineralisation of oclusal enamel surfaces, pronounced as initial occlusal caries lesins.The great advantage in diagnosis offered by KaVo DIAGNOdent laser based on its ability to register and evaluate fluorescent emission of the pulsed beam of the 655 nm wavelength. It enables access to the most minute occlusal routes, otherwise unreachable by other means of diagnosing techniques. Specificity and multidimensional approach is based on the pssibility of diagnosin dental plaque, discoloration and calculus. Simplicity and the ability to produce a reliable and objective clinical diagnosis (> 90 %) are the advantages in comparison with classical radiographic methods and inspection using a probe. It is of great importance in planning noninvasive and preventive conservative treatments. It is recommended for use more frequently in everyday clinical diagnosis of caries lesions, because of it’s less invasive approach in restorative dentistry, which leads to preservation of healthy tooth tissue.

    MeSH:	DENTAL PROSTHESIS, IMPLANT-SUPPORTED REHABILITATION
    Abstract:	Edentulousness is a considerable problem in Croatia. So far prevention has not become the most important part of the dental profession. On the other hand,poor medical knowledge, reduced rights concerning health insurance costs as well as an increasing number of impoverished people in Croatia has resulted in postponed prosthetic rehabilitation. For the above mentioned reasons the Croatian people suffer from premature loss of their teeth. Also lower jaw atrophy occurs, which makes prosthetic rehabilitation even more difficult to achieve. In spite of some disadvantages, the double-implant borne prosthetic suprastructure has proved to be a simpleand good solution to the patient's problem, mainly because it is cost-effective. This particularly applies to Croatia patients. Over the last five years we have placed double -implants in 26 patients, in the anterior region of the mandible. The implants were placed in the region of the lower canine or slightly more mesially. Severe atrophywas determined in 13 patients (50%) which impeded their complete denture wearing even before the implant placement started. However, we made up for the loss in two patients by placing the implants again. This time we placed them slightly more mesially.We made one borne implant complete denture for one patient because the examination revealed severe atrophy in one segment of his mandible. In addition since the osseointegration prognosis for this patient was questionable we decided against any additional surgical treatment. Since the belts of the attached gingiva in our patients were wide enough and the diameters of the implants were not very long, no vestibuloplasty was necessary. We installedITI, IMZ, ASTRA and Ankylos implants. All systems proved to be equally functional.

    Type of Article:	professional paper
    MeSH:	PERIAPICAL DISEASES + pathology
    Abstract:	Chronic periapical lesion is a result of the mutual activity of microbiota in the root canal and multilateral response of the host to infection. Nonspecific, acute and chronic inflammations, including humoral and cellular immunological responses, participate in the occurrence, development and perpetuation of these lesions. Biopsy samples of periapical tissue were taken by surgical procedure in 34 patients, with the object of verifying immunoglobulin classes G, A and M. The study involved determination of total proteins by Lowry’s method. Concentrations of IgG, IgA and IgM were determined by the method of radial immunodiffusion. Their correct amount was obtained by placing them in relation to the verified amount of total proteins. The study revealed different percentages of the share of immunoglobulins, classes G, A and M, and diversity in their values. IgG was found in 100% of cases, IgA in 76% and IgM in 44%. Mean value of the quantity of IgG amounted to 385.2 mg/g protein, ranging in value from 27.3 to 826.0 mg/g protein, IgA 51.0 mg/g protein, ranging from 0 to 336.8 mg/g protein, and IgM 20.3 mg/g, ranging from 0 to156.2 mg/g protein.The results obtained on the basis of this study indicate the local synthesis of immunoglobulins in chronic periapical lesions, and the involvement of nonspecific inflammatory and specific immunological reactions, which together are responsible for the pathogenesis of these lesions.

    MeSH:	BONE RESORPTION
    Abstract:	The problem of healing bone defects of odontogenetic aetiology is the most frequent cause of failure in surgical treatment of an ostitic process. The aim of this study was to valorise the successfulness of healing of bone defects after implantation of a new alloplastic copolymer - polyglycol bone implant (Fisiograft). A group of 45 subjects was examined with an ostitic process on teeth of the intracanine region. The results were valorised on the basis of densitometric measurement over a period of 12 months after implantation. The results obtained indicate that polyglycol copolymer bone implants can be successfully used in the treatment of bone defects of odontogenetic aetiology. Their fundamental advantage is slower biodegradation, which ensures a more suitable area for the apposition of new bone in the lumen of the bone defect, simple application in clinical work and the possibility of a mutual combination of all three available forms.

    Abstract:	Bone morphogenetic proteins are a group of nine known proteins which represent factors of growth and differentiation with the ability of inducing new bone. Osteoinduction is a precisely defined sequence of biological reactions which lead to the transformation of mesenchymal cells into cartilage and bone.In vitro and in vivo, studies have demonstrated that in order for proteins to realise their clinical function they need carriers. So far ACS (absorbable collagen sponge) has been most frequently used as a carrier. However the search for the best carrier continues. Investigations carried out so far on experimental models (rats, dogs, minipigs and chimpanzees), and in human volunteers, have indicated the great potential of BMP in the reconstruction of bone defects of the stomatognathic area. Promising results have been obtained so far in periodontal surgery, augmentation of alveolar ridges, augmentation of the floor of the maxillary sinus, treatment of periimplantitis and treatment of larger bone defects after extirpation of tumours.

    Abstract:	Large bone defects of the jaw have, so far, been filled with various types of bone implants, mainly synthetic nonresporative aloplastic implants (hydroxilapatite). As we have data only for two types of resorptive xenogenic bone implants, the purpose of this investigation was to examine resorption and osteoinductive capability of OSTEOVIT as a material for filling bone defects after removing large cysts (more than 20 mm in diameter) and after apicectomy of the tooth, where more than 1/3 of the tooth has no strong bone bases.Osteovit is a collagen matrix of calf spongiose consisting of porous collagen purified of antigens, fats minerals, enzymes and all other noncollagen materials.Forty-one patients, 9 female and 32 male aged 15-54 years were included in the investigation Nineteen of them had a clinical diagnosis of OPC and 22 a clinical diagnosis of cysts radicularis. All patients had a indication for apicectomy indicating that they had bone defects larger than 20 mm in diameter or destructive alveolus along more than 1/3 of the tooth root.The results are shown on the basis of a clinical follow up and radiographic examination 6 months, 1,2,3 and 4 years after surgery. If, in some cases, a fistula was found during the postoperative followup the treatment was recorded as clinically unsuccessful. Success on the basis of radiographic criteria was also evaluated. First we classified defects into periapical (circumscriptive) and those along the tooth root and than divided the rays into two groups.Unfortunately results for only for 22 patients were abtained and the others were excluded from the investigation because of incomplete follow-up.With regard to total success, according to clinical criterium, 20/22 patients had good clinical diagnosis, i.e. 91%. By radiographic analysis we found complete healing in 13/22 patients or 59%. We also analysed results according to the localization of the periapical change. It was concluded that patients with circumscriptive changes were 88% clinically successful while those with a defect along the tooth root were 93% clinically successful.According to the results of this investigation it can be concluded that OSTEOVIT is a very good resorptive material for filling bone defects and with OSTEOVIT it is possible to widen indication for apicotomy to include cases where more than 1/3 of the tooth has no strong bone base.

    Abstract:	The paper presents two cases of clinical application of polyglycolicpolylactic co-polymer Fisiograft. In the first case periodontal abscess and damaged interradicular alveolar bone of tooth 46 was diagnosed. Interradicular damage to the bone was visible after opening the mucoperiosteal flap. Scaling of the root and careful elimination of the inflamed tissue was performed and the defect filled with Fisiograft implant (Ghimas S.p.A - Italy) in the form of gel and powder, moistened with blood and covered with a coronally positioned flap. Postoperatively the patient was advised to rinse her mouth with 0.2% chlorhexidine digluconate solution. The results of the treatment were monitored clinically and radiographically six months after the procedure. Probing the periodontal pockets before the procedure revealed a depth of 8 mm and loss of the level of periodontal attachment of 10 mm on tooth 46. Clinical evaluation six months after the procedure showed a reduction in the depth of the periodontal pocket from 8 to 4 mm and attachment level gain of 5 mm, which amounts to 50% of the original defect. In the second case, after raising the mucoperiosteal flap of tooth 21, an extensive intrabony defect was revealed, which involved several bony walls. After scaling and planing the root we filled the defect with a Fisiograft implant in the form of gel and powder, moistened with blood. Because of the activity of the periodontal pocket we prescribed Amoxicilin tablets 500 mg, 3 times daily for 5 days. Postoperatively, the patient was advised to rinse his mouth with 0.2% chlorhexidine digluconate solution. Six months after the procedure the clinical finding showed reduced depth of the periodontal pocket and gain of attachment level 4 mm, i.e. 44.5% of the original clinical defect. The radiograph showed reduced radiolucency of the alveolar bone of tooth 21, indicating the formation of new supporting alveolar bone. Thus, it can be said that the application of Fisiograft proved to be successful in regeneration of the alveolar intrabony defect. Six months after the procedure the radiograph showed considerably reduced radiolucency and depth of the periodontal pocket was reduced by around 50%.In the presented two cases the application of Fisiograft proved successful in the process of healing alveolar bone, damaged by periodontitis, and it is therefore proposed that this implant is applied in a larger number of subjects and further investigation carried out.
