This study shows significant changes in the irrigation protocol applied in Serbian dental community. After 3 years of observation, NaOCl became widely accepted as the irrigant of choice, whereas H2O2 lost its popularity.
Background/Aim. The studies of hydroxyapatite (HAp) and growth factors as the materials used for direct pulp capping have produced conflicting results for both the issue of inflammmatory response and the issue of calcified bridge formation. Calcium hydroxyapatite/poly(lactide-co-glycolide) is a bioresorbable polymer with demonstrated good characteristics as the carrier for bone morphogenetic protein (BMP) necessary in bone tissue regeneration. The role of growth factors in dental tissue reparation (in both reactionary and reparative dentinogenesis) represents the new foundation and provides a different approach to dental pulp treatment. Growth factors-TGF-beta 1directly induce morphological and functional differentiation of neodontoblasts. The aim of this experimental study was to investigate the effect of calcium hydroxyapatite/poly(lactide-coglycolide) HAp/PLGA and growth factors (TGF-β1) in the formation of a calcified tissuedentine bridgeon the teeth of our experimental model. Methods. Rodent (rabbit) teeth were used as the animal model. After the trepanation of pulp space with sterile steel drills, the pulp was capped with calcium hydroxyapatite/poly(lactide-co-glycolide) HAp/PLGA (experimental group I; n=60); calcium hydroxyapatite/poly(lactide-co-glycolide) HAp/PLGA combined with TGF-β1 growth factor (experimental group II; n=60), and there was a control group of intact teeth (n=20). The experiment was performed in general anesthesia. The animals were kept alive for 1, 3 and 6 months. The extracted teeth were adequately prepared for scanning electron microscopy.Results. Scanning electron microscopy (SEM) demonstrated that the number of teeth with calcified tissue in the form of dental bridges in the HAp/PLGA+TGF-β1 group was statistically significantly greater 6 months (66.67%) than 3 months after the treatment (26.67%), at the statistical significance level of p<0.05. Conclusion. Direct pulp capping covers the artificially exposed dental pulp and makes possible the formation of a dentine bridge (a tubular structure composed of reparative dentine) in the period of 3 months.
<Zakljucak> Dobro poznavanje mogucih uzoraka prekomernog krvarenja, kao i stomatoloskih postupaka u toku oralnohirurskih intervencija kod obolelih od trombocitopenije, hemofilije, u slucaju snizene koncentracije faktora zavisnih od vitamina K i predozirane antitrombotske terapije, omogucava adekvatnu i blagovremenu oralnohirursku hemostazu u skladu sa predvidjenim protokolom lecenja. Ukoliko je, medjutim, oralnohirurska intervencija propracena produzenim krvarenjem u trajanju od nekoliko sati ili dana, bez pouzdanih anamnestickih podataka i pismene medicinske dokumentacije, problem postaje veliki. U takvim situacijama, podsecanje na stanja koja izazivaju prekomerno krvarenje, kao i na stomatoloske postupke u toku oralnohirurskih intervencija kod takvih bolesnika, moze biti dragocen doprinos dobroj stomatoloskoj praksi.
Dignostic, therapeutic and follow-up advantages afforded by teledentistry have markedly expanded in recent year, and it has been increasingly used in various areas of dentistry. Benefits related to pediatric oral and dental health maintenance and improvement are numerous, presenting an attractive challenge to both clinicians and researchers. The basis of success of teledentistry lies in the effective distant diagnosis of dental diseases and in the provision of a comprehensive insight into therapeutic options. This paper presents a review of teledentistry applications that could be used in pediatric dental. Furthermore, the paper presents critical reviews and recommendations concerning future research in the field.
Laparoscopic cholecystectomy (LC) is the method of choice of surgical treatment of gallbladder diseases. Operations in elderly people over 65 years because of chronic diseases, are often associated with high operative and postoperative morbidity and mortality. The aim of this study was to analyze the outcome of LC in the treatment of cholelithiasis in patients older than 65 years. For evaluation of LC effectiveness and security in old patients, we did this prospective analysis of 81 patients surgically treated because of symptomatic cholelithiasis. We had analyzed associated diseases, operative and postoperative complications, the reasons of conversion to open cholecystectomy. The research points to the small percentage of operative and postoperative complications, short hospital stay, less postoperative pain, quick recovery and savings in treatment. The age can not be contraindication for LC in older patients. In uncomplicated symptomatic cholelithiasis in elderly people, LC is a successful and safe procedure. Complicated symptomatic cholelithiasis, because of longer duration of operations is looking for a good assessment of general condition and associated diseases for LC.
Background / Aim. Hydroxyapatite (HAp) is one of the most commonly used calcium phosphate bioceramics with osteoconductive properties. Growth factors (ТGF-β) are capable of directly inducing morphological and functional differentiation of neodontoblasts. The aim of this paper was to investigate the effectiveness of biomaterials in combination with growth factors in the creation of new dentine and obturation of the root canal apex in the teeth of our experimental model. Methods. Rodent (rabbit) teeth were used as the experimental animal model. After pulp removal with a pulp extirpator in vital pulpectomy, the biomaterial was applied using a Lentulo spiral in the apex portion at the level of the physiological foramen apicale. The experiment was performed in general anesthesia. Animals were kept alive for 3, 6 and 12 months. The extraxted teeth were prepared for scanning electron microscopy (SEM) observation. Results. Using SEM, it was found that the number of teeth with newly created dentine and apex canal obturation was greater 12 months after the treatment. Conclusion. In our experimental groups, apex obturation of the dental root canal with newly created dentine took place.
