[Ab] Resumo:This article demonstrates the clinical application of biomechanical and occlusal principles to conservatively provide optimal clinical outcomes in restoring an eroded anterior dentition. The authors manage a challenging case involving limited palatal clearance (ie, deep bite) coupled with palatal erosion and wear by combining the centric relation (CR) and Dahl principles to create anterior interocclusal space to reduce the need for more invasive palatal reduction. The combined use of adhesive restorations-resin composites on the palatal surface and indirect porcelain veneers on the facial/incisal surfaces-through enamel and dentin bonding helped optimize esthetic and functional/biomechanical aspects. This ultraconservative approach enabled the desired esthetic and biomechanical outcomes to be achieved through the treatment of localized anterior tooth erosion and wear. In short, when treating eroded maxillary anterior teeth with deep bite, adequate restorative space should first be created by conjoining CR and Dahl principles before using adhesive dentistry to restore with bonded composites and porcelain veneers.

[Ab] Resumo:For patients with a single discolored tooth who desire to have it lightened, a thorough examination and radiographic analysis need to be performed prior to initiating any bleaching treatment so that the cause of the discoloration can be determined. Underlying pathology, such as internal resorption, is often asymptomatic and difficult to diagnose and if left untreated could result in tooth loss. This article describes a case of a patient with a discolored maxillary central incisor resulting from internal resorption and the subsequent endodontic and bleaching therapy performed to resolve the pathology and achieve an acceptable esthetic result.

[Ab] Resumo:Placement of an implant in the posterior maxilla often relies heavily on a variety of procedures that increase the vertical dimensions of available bone. With numerous bone graft substitutes now available and recent advancements having been made in technique, the question arises of whether residual bone height still remains an absolute indicator for simultaneous implant placement in lateral wall sinus grafting. In addition to reviewing the literature, the authors present a case in which a direct sinus lift procedure was performed with simultaneous implant placement. The case report demonstrates how implants can be placed in a severely atrophic posterior maxilla and be successful.

[Ab] Resumo:BACKGROUND: A combination of horizontal and vertical third molar impaction is a rare occurrence.When the tooth is unable to erupt to its proper position and fail to achieve a normal occlusion, it is known as impacted tooth. CASE DETAILS: In this scientific article, case report of a female patient aged 30 years reported with acombination of horizontally and vertically impacted third molars in the maxilla and mandible has been presented. The treatment included surgical removal of the impacted teeth without any damage to underlying structures. CONCLUSION: Horizontal impaction of left maxillary third molar, vertical impaction of right maxillary third molar and left mandibular third molar is a rare occurrence. If symptomatic, surgical removal has to be planned as earlier as possible rather than late complications.

[Ab] Resumo:When splinting multiple implants passive fit of the framework should be achieved to avoid excessive force distribution on the implants. Recently, a protocol was suggested for immediate loading of multiple implants by welding a titanium bar to implant abutments directly in the oral cavity so as to create a customized, precise and passive metal-reinforced provisional restoration. The intraoral welding technique subsequently proves to be a successful option in the full-arch immediate restorations of the mandible and maxilla. The aim of this article is to present a case report in which a new prosthetic approach, using trans-mucosal implants, is described. Dental implants are instantly loaded with a provisional prosthesis supported by an intraoral welded titanium framework to obtain a precise passive fit of the immediate loaded prosthesis.

[Ab] Resumo:Labial grooves in maxillary incisors have been reported in several wild-type rodent species. Previous studies have reported age-dependent labial grooves occur in moderate prevalence in C57BL/6 mice; however, very little is known about the occurrence of such grooves. In the present study, we observed age-dependent groove formation in C57BL/6 mice up to 26 months after birth and found that not only the frequency of the appearance of incisor grooves but also the number of grooves increased in an age-dependent manner. We examined the molecular mechanisms of age-dependent groove formation by performing DNA microarray analysis of the incisors of 12-month-old (12M) and 24-month-old (24M) mice. Amelx, encoding the major enamel matrix protein AMELOGENIN, was identified as a 12M-specific gene. Comparing with wild-type mice, the maxillary incisors of Amelx mutants indicated the increase of the frequency and number of labial grooves. These findings suggested that the Amelx gene impacts the age-dependent appearance of the labial incisor groove in C57BL/6 mice.

[Ab] Resumo:INTRODUCTION: The purpose of this study was to evaluate the reliability of the radiographic images of the main conventional x-ray techniques compared with the information from cone-beam computed tomography (CBCT). METHODS: Twenty patients with unilateral or bilateral impaction of the maxillary canines had radiographic examinations by means of periapical x-rays, occlusal x-rays, panoramic x-rays, and CBCT scans. Three experienced orthodontists examined all x-rays from each patient and evaluated the radiographic images of the impacted canines. The examiners were asked to detect resorption in adjacent teeth and the buccal-palatal position of the impacted canines. Agreement between examiners was statistically tested. RESULTS: Different diagnoses were produced by the 3 examiners regarding localization of the impacted canines and the presence or absence of root resorption of the adjacent teeth in conventional radiographic images. It appears that whereas panoramic x-ray is more sensitive in detecting resorption and tooth position, occlusal and periapical imaging have higher specificity and positive predictive value. The examiners were in good or excellent agreement when occlusal and periapicals were used for the definite diagnosis of resorption and tooth position. There was no disagreement of the examiners in CBCT images, which were used as the gold standard. CONCLUSIONS: Conventional radiographic methods demonstrated a more subjective diagnostic procedure compared with CBCT images. CBCT is a more accurate and precise examination method compared with conventional radiography for the localization of impacted teeth and root resorption of the adjacent teeth.

[Ab] Resumo:INTRODUCTION: Orthodontic treatment of palatally impacted maxillary canines raises many difficulties; to minimize complications, careful planning of orthodontic extrusion and the use of physiologic force are crucial. The aim of this study was to quantitatively evaluate a simple and reproducible system for orthodontic extrusion of impacted canines that can provide the correct amount of force. METHODS: Ten specimens were constructed, consisting of a cantilever made with a 0.6-mm or 0.7-mm stainless steel wire modeled around a transpalatal bar with 3, 5, or 7 loops in the shape of a helical torsion spring. A mechanical testing machine was used to measure the force produced by the cantilever at 3, 6, 9, 12, and 15 mm of activation. RESULTS: The force values ranged from 1.24 ± 0.13 N for the 0.7-mm wire with 3 loops to 0.48 ± 0.04 N for the 0.6-mm wire with 7 loops. The forces measured for the 0.6-mm wire with 3 loops and the 0.7-mm wire with 7 loops were similar at 15 mm of deflection. CONCLUSIONS: The proposed system has a simple and robust design, is easy to construct and manage, and can provide the desired amount of force by changing the wire diameter and number of loops.

[Ab] Resumo:To establish SD rat model with type 2 diabetes mellitus (DM) and concomitant chronic periodontitis (CP) and to evaluate the influence of periodontitis on the vascular lesions of type 2 diabetes rats. Totally 241 clean level SD rats were randomly divided into four groups, group A (normal control, NC, 27), group B (DM, 34), group C (CP, 90) and group D (DM+CP, 90). The rats of DM group were fed with high-fat and high-sugar diet for 8 to 10 weeks, and then were multiply injected with small dose streptozotocin under the condition of ice bath. Blood sugar levels after the injection were dynamically monitored at 72 h, 1 week, 2 weeks and 4 weeks, respectively. The CP model was established by means of ligation. Bilateral maxillary first and second molars were selected and ligated using 0.2 mm orthodontic wires binding with 4-0 surgical suture soaked with (Pg) suspension. After a period of 14 weeks, all the rats were put to death. Maxillary samples were subjected to methylene blue staining to observe alveolar bone loss. Bilateral carotid artery specimens were collected. The left carotid artery specimens were used to detect the prevalence of Pg using quantitative real-time PCR. The right carotid artery specimens were used to observe pathological changes. Blood sugar levels of rats in group B and D increased and changed sharply after Streptozotocin injection with in 1 week. Symptoms of 'more drink, more food and body weight loss' appeared. The fasting blood glucose (FBG) was more than 7.8 mmol/L and (or) the random blood glucose (RBG) was more than 17.8 mmol/L. Both FBG and RBG became stable after 2 to 3 weeks. Levels of HbA1C in group B and D ([7.32±0.45]%, [9.41±0.45]%) were significantly higher than that of group A ([4.02±0.45]%) ( 0.01). Rats of group D were observed the most severe bone loss showing wider interdental space and furcation involvement. Pathological results of carotid artery tissues of group D showed the worst lesions including thinning and calcification of vessel walls, and breaking down or disappearance of elastic fibers. The prevalences of DNA of Pg in groups of A, B, C and D were 3/7, 3/7, 6/7 and 7/7, respectively. The bacteria numbers detected by quantitative real-time PCR in groups C and D were significantly higher than that of groups A and B ( 0.01). Rat model of type 2 DM with periodontitis was successfully established in the present study. Carotid artery specimens from DM+CP model rats showed typical vascular lesions such as calcification and fiber disorders. Pg was found in all carotid specimens and the highest bacteria numbers were detected in the composite model rats. The Pg might play a role in the progress of diabetes vascular lesions.
