Impact of Replacing Conventional Complete Dentures with Implant-Supported Fixed Complete Dentures

The aim of this study was to assess the impact of replacing conventional mandibular complete dentures with implant-supported fixed complete dentures (ISFDs) on the oral health related quality of life (OHOOL) of edentulous patients and on the associated kinesiographic parameters. The patients had their complete dentures replaced by ISFDs and were assessed after 1, 2, 3, 6, and 12 months. An improvement of general OHQOL was observed 2 months after treatment with ISFDs. Kinesiographic recordings revealed significant mandibular vertical and horizontal opening increases and a greater vertical intrusion of the maxillary complete dentures during clenching after the treatment with ISFD.

Acidentes na infância atendidos no pronto socorro de pediatria do Hospital das Clínicas de Botucatu que motivaram internação

Accidents represent a major public health problem as they are frequent, preventable, and account for high morbidity and mortality rates. Children are the most vulnerable to accidents due to their inherent characteristics, and as a result of their physical, sensorial, psychomotor and cognitive limitations, which will only develop with time. Watchfulness and careful attention are of paramount importance, especially as children develop locomotor skills that are accompanied by curiosity about their surroundings. Child accidents, particularly those that could have been avoided, are the accidents most commonly seen in emergency and urgency departments. Urgency and emergency departments are the greatest allies in the attention to pediatric accidents as they offer adequate, immediate and specific high complexity care to patients at risk, viewing their vital stabilization. Investigating the causes and consequences of this insult is essential to establish a diagnosis and to contribute for the adoption of measures of prevention, control, and assistance. To identify the epidemiologic characteristics of the accidents involving children that received care at the pediatric emergency department of Botucatu Medical School Hospital and required hospitalization. This quantitative, retrospective, descriptiveanalytic epidemiologic study included all children aged 0-14 years who had had an accident and were seen at the Pediatric Emergency Department of Botucatu Medical School Hospital of São Paulo State University/UNESP between January 1/2008 and December 31/2009. A total of 227 medical charts were reviewed and 178 (78.4%) patients were included in this study. Of these, 116 (65.1%) were males and 62 (34.8%) were females. Children aged 5 - 9 years (38.9%) were the most affected, followed by those aged 10 - 14 years (37.5%). Fractures occurred in 138 (77.5%) of the cases, followed by foreign bodies...

Avaliação das alterações dentárias e esqueléticas induzidas pelo uso do aparelho de Herbst no tratamento da classe II na dentadura mista: Revisão sistemática

Objective: evaluate the immediate dental and skeletal changes induced by the Herbst appliance on early treatment of Angle´s Class II malocclusion. Material and Method: several electronic databases such as Scopus, Pub Med, Medline, Cochrane Library, Lilacs and Scielo were searched. The abstracts that fullfilled the selection criteria were selected and those that did not provide enough information about these criteria were selected but the final decision of including them or not on the research, was taken after the complete reading of the article. The selection criteria were: clinical studies with Class II individuals, both male and female, with initial age of 7 to 10 years, treated with the Herbst appliance that analysed the dental and/or skeletal changes evaluated on lateral cephalometric radiographs; researches where the treatment performed did not involve extractions or surgical interventions; studies that included patients without syndromes or health concerns and articles published in English or Portuguese. Results and Conclusions: five articles were selected. The articles showed that significant changes happened in the mandibular sagittal lenght, on facial convexity angle, on maxillo-mandibular relationship, on retroclination of the upper incisors and on distal movement of the upper molars, on proclination of the lower incisors and on extrusion of the lower molars. The appliance exerted a limited effect on the anterior relocation of the maxillary complex and on facial heights. However, more studies about the performance of the Herbst appliance on early treatment of Class II are needed.

Aesthetic rehabilitation of oligodontia in primary dentition with adhesive partial denture

The primary teeth are essential for bone development and establishment of the arches on occlusion. Thus, the congenitally absence of teeth may trigger a shift in the balance of the occlusion, promoting disharmony in the structures of the maxilla-mandibular system. However, some interventions are possible to be performed in these cases even in pediatric patients, to redirect growth, preventing growth deviations and reestablishing the aesthetic. The aim of this paper is to report the treatment of a 4-year-old child presenting congenitally absence of mandibular central and lateral incisors and maxilla lateral incisors, which consequently compromises aesthetics, occlusal function, and the development and the functional growth of the bones. The oral rehabilitation was performed with an adhesive partial denture, which was able to restore the aesthetic and the occlusal function, therefore being a viable alternative in the treatment of this patient of little age.

Immediate human pulp response to ethanol-wet bonding technique

To evaluate the short-term response of human pulps to ethanol-wet bonding technique. Methods Deep class V cavities were prepared on 17 sound premolars and divided into three groups. After acid-etching, the cavities from groups 1 (G1) and 2 (G2) were filled with 100% ethanol or distilled water, respectively, for 60 s before the application of Single Bond 2. In group 3 (G3, control), the cavity floor was lined with calcium hydroxide before etching and bonding. All cavities were restored with resin composite. Two teeth were used as intact control. The teeth were extracted 48 h after the clinical procedures. From each tooth serial sections were obtained and stained with haematoxylin and eosin (H/E) and Masson's trichrome. Bacteria microleakage was assessed using Brown & Brenn. All sections were blindly evaluated for five histological features. Results Mean remaining dentine thickness was 463 ± 65 μm (G1); 425 ± 184 μm (G2); and 348 ± 194 μm (G3). Similar pulp reactions followed ethanol- or water-wet bonding techniques. Slight inflammatory responses and disruption of the odontoblast layer related to the cavity floor were seen in all groups. Stained bacteria were not detected in any cavities. Normal pulp tissue was observed in G3 except for one case. Conclusions After 48 h, ethanol-wet bonding does not increase pulpal damage compared to water-wet bonding technique. Clinical significance Ethanol-wet bonding may increase resin-dentine bond durability. This study reported the in vivo response of human pulp tissue when 100% ethanol was applied previously to an etch-and-rinse simplified adhesive system.

Radical management of solid ameloblastoma of the mandible: report of a case with 5-year follow-up

Ameloblastoma is a true neoplasm of odontogenic epithelial origin. This pathology can be classified into 4 groups: unicystic, solid or multicystic, peripheral, and malignant. Solid ameloblastomas of the mandible are the most common of them, and represent a challenging group of tumours to treat; in addition the follicular histopathological subtype has a high likelihood of recurrence. Thus, the challenges in the management of this tumour are to provide complete excision in addition to reconstruct the bony defect, in order to provide the patient with reasonable cosmetic and functional outcome. With this in mind, this paper aimed to describe the management of a solid multilocular ameloblastoma of follicular subtype in a 39-year-old female. Case report The authors report a case of a solid multilocular ameloblastoma of follicular subtype in a 39-year-old female who was successfully treated by partial resection of the mandible with immediate reconstruction using an iliac crest, as a donor site. After 15 months, the patient was rehabilitated using titanium implant dentistry, and has been followed up for 5 years without signs or symptoms of recurrence. Conclusion Correct surgical planning is the key for successful management of solid ameloblastoma with multilocular features, which is best treated using radical resection with immediate reconstruction, which ensures complete tumour excision, prevents recurrence, and enables fast and safe dental rehabilitation. Biomedical prototypes should be used since they provide acceptable precision and are useful for surgical planning.

A utilização do enxerto ósseo autógeno para tratamento de lesão de furca grau II

Destruction of bone and periodontal ligament as a result of periodontal disease can lead to anatomical defects in the furcation area. Treatment of these lesions is a major challenge to the clinician. Periodontal instruments have limited access to this area and plaque and calculus removal from root surfaces are extremely difficult. For proper treatment planning a number of factors must be taken into consideration to achieve immediate and long term success. Surgical therapy associated with bone grafts may be a viable option in the treatment of class II furcation defects, aiming to restore lost tissues. The aim of this paper is to report a clinical case where a simplified surgical approach with the use of autogenous graft was used to treat a class II furcation defect Twelve months after the surgery, an increase in clinical attachment level and pocket depth reduction resulted in a complete closure of the furcation lesion.

A combined approach for the treatment of resorbed fresh sockets allowing immediate implant restoration: a 2-year follow-up

Introduction: The demand for optimal esthetics has increased with the advance of the implant dentistry and with the desire for easier, safer and faster technique allowing predictable outcomes. Thus, the aim of this case report was to describe a combined approach for the treatment of a periodontally compromised tooth by means of atraumatic tooth extraction, immediate flapless implant placement, autogenous block and particulate bone graft followed by connective tissue graft and immediate provisionalization of the crown in the same operatory time. Case Report: A 27-year-old woman underwent the proposed surgical procedures for the treatment of her compromised maxillary right first premolar. The tooth was removed atraumatically with a periotome without incision. A dental implant was inserted 3 mm apical to the cement-enamel junction of the adjacent teeth enabling the ideal tridimensional implant position. An osteotomy was performed in the maxillary tuber for block bone graft harvesting that allowed the reconstruction of the alveolar buccal plate. Thereafter, an autogenous connective tissue graft was placed to increase both the horizontal and vertical dimensions of the alveolar socket reaching the patient functional and esthetic expectations. Conclusion: This treatment protocol was efficient to create a harmonious gingival architecture with sufficient width and thickness, maintaining the stability of the alveolar bone crest yielding excellent aesthetic results after 2-years of follow-up. We suggest that this approach can be considered a viable alternative for the treatment of periodontally compromised tooth in the maxillary esthetic area enhancing patient comfort and satisfaction.

Reabilitação oral de paciente com síndrome da combinação: relato de caso

The Combination Syndrome represents an important pathologic condition of the masticatory system that requires a complex rehabilitation treatment. The presence of flaccid mucosa is one of the most common features due to bone resorption of the pre-maxilla caused by anterior hyperfunction of the mandibular teeth on the maxillary complete denture, where the impact of oclusal loading in this region results in movement of the maxillary prosthesis into the ridge, resulting in increased resorption of the residual ridge, internal misfit and loss of the retention of the maxillary complete denture. The presence of flaccid mucosa, in such cases, leads to problems of support and stability of the maxillary complete denture, which can be treated by surgical reduction of the thickness of the tissue or using specific techniques of fabrication of prostheses. This article describes the oral rehabilitation of a patient with the Combination Syndrome where the surgical reduction of flaccid mucosa was not performed, using a modified technique of functional impression in two steps, with the objective of generating forces and less distortion in flaccid mucosa during functional impression.
