[Ab] Resumo:Gutta-percha is a tough plastic substance from the latex of several Malaysian trees of the sapodilla family that resembles rubber but contains more resin. It is especially used as insulation and in dentistry. Gutta-percha endodontic filling points were found to contain approximately 20% gutta-percha (matrix), 66% zinc oxide (filler), 11% heavy metal sulphates (radiopacifier), and 3% waxes and/or resins (plasticiser). The mechanical properties were indicative of a partially crystalline viscoelastic polymeric material.

[Ab] Resumo:Endodontic surgery aims at the resolution of a periapical inflammatory process by surgical access followed by enucleation of the lesion and root-end filling to curb any potentially noxious agent within the physical confines of the affected root. Guided bone regeneration could be associated to endodontic surgery aiming to enhance periradicular tissue regeneration. The objective of this paper was to review the scientific literature about guided bone regeneration in endodontic surgery, evaluating the effects on periapical lesion healing process. The included articles are classified considering the anatomical characteristics of the lesion. Fourteen articles were included in the review after abstract and title selection. Eight articles were on studies on lesions affecting only the periapical region (three about through-and-through lesions) while six were about the treatment of apico-marginal lesions. On the basis of the currently available literature, there is a low scientific evidence of a benefit related. to the use of guided bone regeneration procedure in endodontic surgery.

[Ab] Resumo:The aim of this study was to analyze the radiopacity and filler content of three experimental glass fiber posts (EGFP) in comparison with other glass/carbon fibers and metal posts from the dental market. Three EGFP were obtained by pultrusion of glass fibers in a polymer matrix based on 2,2-bis[4-(2-hydroxy-3-methacryloyloxypropoxy)-phenyl]propane (bis-GMA) and triethyleneglycol dimethacrylate (TEGDMA) monomers. Using intraoral sensor disks 27 posts, as well as mesiodistal sections of human molar and aluminum step wedges were radiographed for evaluation of radiopacity. The percentage compositions of fillers by weight and volume were investigated by combustion analysis. Two EGFP showed radiopacity higher than enamel. The commercial endodontic posts showed radiopacity as follows: higher than enamel, between enamel and dentin, and lower than dentin. The results showed statistically significant differences (p b 0.05)when evaluatedwith one-way ANOVA statistical analysis. According to combustion analyses, the filler content of the tested posts ranges between 58.84wt.% and 86.02wt.%. The filler content of the tested EGFP ranged between 68.91 wt.% and 79.04 wt.%. EGFP could be an alternative to commercial glass fiber posts. Futureglass fiber posts are recommended to present higher radiopacity than dentin and perhaps ideally similar to or higher than that of enamel, for improved clinical detection. The posts with a lower radiopacity than dentin should be considered insufficiently radiopaque. The radiopacity of some glass fiber posts is not greatly influenced by the amount of filler.

[Ab] Resumo:The aim of this study was to present in detail the clinical steps of the root-membrane technique. This technique combines the benefits of conventional root submergence via intentional maintenance of a root fragment for ridge preservation with those of immediate implant placement for functional rehabilitation of the treated site. A case study of a tooth diagnosed with a horizontal root fracture is used to illustrate this technique step by step. The clinical application of the root-membrane technique not only allowed for immediate placement in a site with compromised buccal plate but also facilitated excellent clinical stability of soft tissue contours during the 3 years of follow-up.

[Ab] Resumo:Enduring a period of edentulism between extraction and final restoration is difficult for patients- especially when it concerns the esthetic zone. The approach described demonstrates key points of consideration when replacing a maxillary anterior tooth with a dental implant using immediate implant placement, hard- and soft-tissue augmentation, and provisionalization. The authors stress adherence to patient selection and prosthetic design guidelines, and recommend the use of a digital impression technique, rather than traditional, rubber-based impressions.

[Ab] Resumo:The Sturge-Weber (SWS) syndrome is a rare condition with congenital capillary malformations. Hemorrhages may occur on dental treatment, which can have a dramatic effect on a patient's vital sign. The aim of the present brief clinical study was to briefly report a case of a female patient with SWS who underwent an endodontic treatment. A 25-year-old patient (C.O.B.S.) with SWS and vascular malformation in cervicofacial right region was admitted to the dental clinic with pulsatile pain in tooth 16. An emergency dental treatment with cavity preparation and access to root canals was performed with intraligamentary and intrapulpal anesthesia with 3% prilocain 3% with felypressin 0.03 UI/mL because the tooth was located in the region of the vascular malformation, and any surgical treatment could lead to hemorrhages. After 7 days, the patient was recalled with the absence of painful symptoms. The endodontic treatment in patients with SWS is feasible, and safety should be an alternative to surgical treatments.

[Ab] Resumo:INTRODUCTION: The aim of this study was to compare the biological interaction of human osteoblasts and cells of the human periodontal ligament (PDL) with different endodontic restorative material as Mineral Trioxide Aggregate (MTA), Biodentine, amalgam and composite over a time period of 20 days. MATERIALS AND METHODS: Human PDL cells and osteoblasts were harvested, cultured and according to standardized protocols. The cell populations were characterized with the corresponding surface markers following standardized procedures. The specimens were produced with special regard to constant dimensions and volume in the different groups. Cell attachment and proliferation were evaluated morphologically after Richardson staining and cell count was performed after 1d, 8d, 13d and 20d. All experiments were performed in triplets. The results were statistically analyzed using the ANOVA- and Tukey-test (p < 0.05). RESULTS: Morphological analysis proved good proliferation and cell attachment in both cements. A remarkable result was the organized spreading and parallel alignment of the PDL cells in contact with MTA and especially Biodentine (cells maturing in a second cell layer crossway to the first one). From 8d onward Biodentine showed the highest quantity of PDL cells (p < 0.05). Biodentine and MTA resulted in a significantly higher cell density in osteoblast and PDL cell culture. The other groups showed a lower PDL cell density from 8d and a lower osteoblast cell density from 13d when compared to control and cement samples (p < 0.05). CONCLUSIONS: MTA and Biodentine showed a good biocompatibility in contact with the human osteoblasts and cells of the periodontal ligament. Regarding cell survival and proliferation particularly of PDL cells Biodentine showed good results and can be considered as a well-tolerated bioactive endodontic material.

[Ab] Resumo:OBJECTIVES: The goal of this study was to evaluate bone changes around endosseous implants in partially edentulous patients. MATERIALS AND METHODS: A total of 632 two-stage implants were placed in 252 patients. The implants had straight emergence profile, ZirTi surface, 3.3 to 5 mm diameter, and 8.5 to 13 mm length. Bone levels were assessed on orthopantomography immediately after surgery and after 36 months and marginal bone loss (MBL) was calculated from their difference. RESULTS: Cumulative survival rate was 98.73%. Overall MBL was 0.8 mm ± 0.03 (mean ± SEM). Higher MBL was observed around implants in the maxilla than in the mandible (P < 0.007). A relation between implant diameter and MBL (P < 0.0001) was observed in male and, more limitedly, female patients. Older patients had higher MBL in the maxilla, but not in the mandible (P < 0.0001). MBL progressively increased with age in male patients, but reached a peak already in the 50-60 years age group in the female subset (P < 0.001). CONCLUSIONS: The overall MBL is consistent with the available literature. Site difference and patient age and gender appear to significantly affect MBL, representing important factors to be considered during implant placement.

[Ab] Resumo:Previous studies on the endodontic broken stainless steel instruments have mainly focused on retrieval of specimens. However, the systemic consequences of the retained separated instruments need an investigation. The current study aimed to evaluate the correlation between broken stainless steel instruments inside the root canal space and the urinary level of iron (Fe) in patients. Sixty near-aged and same-gender patients were selected. Thirty patients in the control group had no endodontic treatment in their history, while the other 30 patients in the endodontic group had broken stainless steel instrument. The urine samples were collected in iron-free containers. All specimens were refrigerated for 1 day and then subjected to Fe level measurement by electrothermal atomic absorption spectrometry. Data were analyzed by Kolmogorov-Smirnov and t tests at P < 0.05. The correlation coefficients of age and sex were also evaluated in relation with Fe levels in the urine. The level of Fe did not show any significant increase in the experimental group (P > 0.05). There was a positive correlation between age and Fe levels of endodontic and control groups. However, the joint effects of age and sex on Fe levels were different for the two groups. The presence of broken stainless steel instruments inside the root canal space did not elevate the level of Fe in the urine of patients. However, this value was positively correlated with the patient age.
