O dente tem vitalidade pulpar e tem lesão periapical: critérios para o diagnóstico e condutas / The tooth has pulp vitality and has a periapical lesion: Criteria for diagnosis and treatment

Muitos profissionais ficam confusos quando um dente tem lesão periapical e mantém a vitalidade pulpar. Muitas lesões imitam imagiologicamente as lesões periapicais crônicas inflamatórias e os dentes permanecem com vitalidade pulpar. Sempre devemos lembrar que: 1) dentes com vitalidade pulpar não devem ser abertos sem um diagnóstico prévio das lesões que são portadores; tratamento endodôntico não deve ser aplicado como meio de diagnóstico ou teste terapêutico de lesões periapicais em dentes com vitalidade pulpar. 2) Realizar tratamentos endodônticos em dentes com vitalidade pulpar e com lesões que imitam periapicopatias pode prolongar o tempo de uma abordagem adequada e piorar em muito o prognóstico da lesão. 3) Em dentes com vitalidade pulpar e lesões periapicais de origem a determinar, é muito importante a inter-relação clínica, imagiológica e microscópica para a troca de experiências e conhecimento, visando um diagnóstico seguro e terapêutica eficaz. 4) As lesões relacionadas devem ser mentalizadas ou anotadas para que se aplique sempre frente a dentes com lesões periapicais e com vitalidade pulpar!

Implante imediato associado ao enxerto de tecido conjuntivo: relato de caso clínico / Immediate implants with connective tissue association: a case report

Os implantes imediatos são uma realidade e também uma evolução das técnicas primeiramente preconizadas para reabilitação implantar, as quais visavam apenas, reabilitação de mandíbulas em axilas edêntulas, em que as exodontias tinham sido realizadas há algum tempo, e o osso alveolarjá se encontrava remodelado. A implantação imediata é uma técnica onde o implante é instalado no alvéolo fresco, imediatamente após a exodontia. A vantagem dessa modalidade de tratamento é a redução do tempo clínico, além da preservação da forma dos tecidos moles circundantes ao implante, preservando a arquitetura peri-implantar, otimizando a estética. Porém, antes de realizarmos este tipo de procedimento devemos avaliar a real indicação da colocação do implante concomitante a exodontia, através de exames clínico e radiográfico, pois um fator de extrema importância para o sucesso desta técnica, é que o implante instalado consiga uma boa estabilidade primária no momento da instalação. Os implantes imediatos podem ser incorporados como uma técnica a ser realizada em diversos casos clínicos, devendo sempre ser observadas as limitações dos casos a fim de serem alcançados excelentes resultados. Este trabalho tem por objetivo o relato de um caso clínico onde é realizada a instalação de implantes imediatamente após a exodontia.

Immediate implants are a reality and also an evolution of the first recommended techniques to implant rehabilitation, which were aimed only rehabilitation of the edentulous upper and lower jaws where the extractions were carried out for some time, and the alveolar bone was already renovated. The immediate implantation is a technique where the implant is installed in the fresh socket immediately after extraction. The advantage of this mode of treatment is to reduce the clinical time, inaddition to preservation of the shape from the surrounding soft tissue around the implant preserving the peri-implant architecture, optimizing the aesthetics. But before we perform this type of procedure we must assess the real indication of the placement of concomitant implant tooth extraction,through clinical and radiographic examinations cause a factor of great importance for the success ofthis technique is that the installed implant achieve a good stability primary at installation time. Immediate implants can be incorporated as a technique to be used in several clinical cases and should always be subject to the limitations of the cases to be achieved excellent results. This work aims to report a clinical case where implant installation is performed immediately after extraction.

Enxerto ósseo em bloco autógeno na maxila: relato de caso clínico / Autogenous block bone graft in the upper jaw: report of case

A instalação de implantes em áreas com perda óssea pode estar associada a uma relação coroa-implante desfavorável, resultado estético insatisfatório e dificuldades de higienização, prejudicando o prognóstico do tratamento. O enxerto ósseo possibilita a instalação de implantes em uma posição tridimensional favorável. Alguns métodos têm sido estudados e propostos para a reconstrução do osso alveolar perdido: enxertos ósseos autógenos, homógenos, substitutos ósseos alógenos, xenógenos e aloplásticos. Ainda existe a regeneração óssea guiada, distração osteogênica, fatores de crescimento e as combinações destas referidas metodologias. Dentre os materiais disponíveis, o osso autógeno é tido como primeira opção para a reconstrução óssea,tido como padrão ouro em enxertia óssea, pois fornece as condições mais favoráveis de reparo pós-cirúrgico, por apresentar as propriedades de osteocondução, osteoindução e osteogênese,auxiliando na correção de defeitos de espessura, desde que haja um bom suprimento vascular no local. Neste trabalho é demonstrada uma técnica de enxertia óssea em bloco autógeno, através da realização de um caso clínico, para a reconstrução de maxila atrófica, visando o aumento do volume ósseo disponível para a instalação de implantes dentais.

The installation of implants in areas of bone loss may be associated with an unfavorable ratiocrown-implant, unsatisfactory aesthetic result and cleaning difficulties, impairing treatment prognosis. The bone graft allows the installation of implants in a favorable three-dimensional position. Some methods have been studied and proposed for the reconstruction of lost alveolar bone: autogenous bone grafts, homogeneous bone, allogenic, xenogenous and alloplasticbone substitutes. There is still the guided bone regeneration, distraction osteogenesis, growth factors and combinations of these referred methodologies. Among the materials available, the autogenous bone is considered as the first option for bone reconstruction, considered the gold standard in bone grafting because it provides the most favorable conditions for post-surgical repair, presenting the properties of osteoconductive, osteoinductive and osteogenesis, helping the correction of the defects of thickness, since there is a good blood supply in the area. Thiswork shows a bone grafting technique in autogenous block by performing a case for the reconstruction of atrophic maxilla, in order to increase bone volume available for the installation of dental implants.

Checagem dos modelos precisos na Implantodontia através do “Index de resina” / Using the “resin Index” to check the accuracy of the plaster model in implantology

A perfeita adaptação passiva das próteses sobre implantes é um fator importante para a obtenção do sucesso na Implantodontia. Para tanto, a eliminação de variáveis que possam afetar o processo de confecção de uma estrutura protética é fundamental, essas vão desde o procedimento de moldagem até a execução da peça protética, sendo que essa fase representa a transição da situação clínica para a fase laboratorial; desta maneira, o modelo de trabalho deve ser o mais preciso possível para evitar qualquer tipo de diferença significativa na adaptação final do trabalho. A confecção, em boca, do “Index de resina” é para auxiliar a conferencia dessa precisão de adaptação no modelo de gesso, eliminando futuros problemas no assentamento das estruturas, na dissipação das cargas mastigatórias e comprometimento da qualidade final do trabalho. Isto se torna imprescindível quando utilizamos a tecnologia CAD/CAM, pois as estruturassão fresadas em monobloco, onde se obtém uma estrutura única em que o assentamento passivo depende diretamente das informações de posicionamento dos análogos, passadas ao software através do modelo de gesso que foi previamente escaneado.

The perfect passive adaptation of the implant prosthesis is an important factor to achievesuccess in implantology. Therefore, the elimination of variables that can affect the process ofprosthetic construction is critical. These variables range from dental impression technique until the final execution of the implant supported prosthesis. The Prosthetic phase is the transition ofthe clinical situation to the laboratory phase; this way, the working model must be as accurateas possible to avoid any significant difference in the final adaptation of the restoration. Theproduction, in mouth, of the “resin Index” is to assist the conference of the precision fit on thestone model, eliminating future problems in the settlement of structures, dissipation of masticatory loads and commitment of the final quality of work. This becomes more imperative whenwe use the CAD / CAM technology, because the structures are milled in a single block where youget a unique structure in which the liability settlement depends directly on the analog position information, passed to the software through the plaster model that was previously scanned.

High-power diode laser versus electrocautery surgery on human papillomavirus lesion treatment.

The use of high-power lasers has facilitated and improved human papillomavirus (HPV) treatment protocols and has also become very popular in recent years. This application has been more frequently used in hospitals, especially in gynecology. The present study aimed to evaluate the effects of high-power diode laser to remove oral lesions caused by HPV and the consequent effects on virus load following the wound tissue healing process compared with one of the most conventional surgical techniques involving electrocautery. Surgeries were performed on 5 patients who had 2 distinct lesions caused by HPV. All patients were submitted to both electrocautery and high-power diode laser. Following a 20-day period, when the area was healed, sample material was collected through curettage for virus load quantitative analysis.Observation verified the presence of virus in all the samples; however, surgeries performed with the laser also revealed a significant reduction in virus load per cell compared with those performed with electrocautery. The ease when handling the diode laser, because of the flexibility of its fibers and precision of its energy delivery system, provides high-accuracy surgery, which facilitates the treatment of large and/or multifocal lesions. The use of high-power diode laser is more effective in treatment protocols of lesions caused by HPV.

The use of surgical diode laser in oral hemangioma: a case report.

OBJECTIVE: To review the literature regarding the use of surgical lasers in hemangioma treatment and to report a clinical case involving diode laser. BACKGROUND: Hemangiomas are benign vascular proliferations consisting of numerous capillary structures and are especially common on the tongue, lips, jugal mucous membrane, and gums. A number of treatment modalities have been proposed for hemangioma treatment. METHODS: The patient was referred for evaluation complaining of chewing difficulty because of swelling in the right area of the upper lip, with no previous trauma. The lesion was located in the internal right jugal mucous membrane, measured 4 x 4 cm(2), presented a bluish coloration, and was diagnosed as a hemangioma. The treatment selected was surgical removal using gallium arsenide (GaAs) diode laser at 980 nm wavelength, with 4.0 W of power. RESULTS: During surgery, complications including hemorrhage were not observed, and no scarring developed after surgery. CONCLUSIONS: The use of GaAs high-potency diode laser in the treatment of hemangioma reduced bleeding during surgery, with a consequent reduction in operating time, and promoted rapid postoperative hemostasis. It is safe for use on large lesions and easy to manage, and postoperative problems, including potential scarring, and discomfort are minimal.

Different approaches to dental management of self-inflicted oral trauma: oral shield, botulinum toxin type A neuromuscular block, and oral surgery.

OBJECTIVE: To assess different approaches to the dental management of lip injuries caused by self-inflicted oral trauma in 7 patients. METHOD AND MATERIALS: The patients were grouped based on 3 treatment approaches: group 1, placement of an oral appliance; group 2, botulinum toxin type A neuromuscular block; and group 3, oral surgery. RESULTS AND CONCLUSION: Neuromuscular block can be the first choice of treatment for patients with self-injurious behavior since botulinum toxin A injection is a well-tolerated, safe, and effective procedure, permitting improvement in muscle spasticity, bruxism, range of mouth opening, oral hygiene, and lip trauma. The second option would be the use of the oral appliance, and the last choice is oral surgery. Laser therapy was also found to be effective when applied to traumatic injuries in patients who present self-inflicted oral trauma.

Photodynamic therapy for root canals infected with Enterococcus faecalis.

OBJECTIVE: The aim of this study was to investigate the effects of photodynamic therapy (PDT) on endodontic pathogens by evaluating the decrease in numbers of Enterococcus faecalis colonies in the canals of extracted human teeth. BACKGROUND DATA: Failure in endodontics is usually related to inadequate cleaning and disinfection of the root canal system. This is due to the establishment of microorganisms in areas where the instruments and chemical agents used during root canal preparation cannot eliminate them. PDT is a complementary therapeutic method that could be used to eliminate these remaining bacteria. PDT is a process in which radiation acts on a dye that is applied to the target organism, resulting in bacterial death. MATERIALS AND METHODS: Forty-six uniradicular teeth had their canals contaminated with bacteria and were incubated for 48 h at 35 degrees C. After that, the teeth were divided into a control group (CG) and a test group (TG). The 23 CG teeth did not undergo any intervention, whereas in the TG the teeth received a solution of 0.0125% toluidine blue for 5 min followed by irradiation using a 50-mW diode laser (Ga-Al-As) at a wavelength of 660 nm. Bacterial samples were taken before and after irradiation. In each of the samples, the number of colony-forming units (CFU) was counted. RESULTS: The mean decrease in CFU was 99.9% in the TG, whereas in the CG an increase of 2.6% was observed. CONCLUSION: PDT was effective as a bactericidal agent in Enterococcus faecalis-contaminated root canals.

Effect of GaAIAs laser on reactional dentinogenesis induction in human teeth.

OBJECTIVE: This study investigated the biomodulatory effect of the gallium- aluminum-arsenate laser (GaAlAs) in pulp cells on reactional dentinogenesis, and on the expression of collagen type III (Col III), tenascin (TN), and fibronectin (FN) in irradiated dental tissues and controls (not irradiated). BACKGROUND DATA: Several studies suggest a biomodulatory influence of low-intensity laser radiation in the inflammatory and reparative processes of biological tissues. METHODS: Sixteen human premolar teeth were selected (after extraction due to orthodontal reasons) and divided into irradiated and control groups. Black class V cavity preparations were accomplished in both groups. For the irradiated group, GaAlAs laser (670 nm, 50 mW) with an energy density of 4 J/cm2 was used. Soon after, the cavities were restored with a glass ionomer and the extractions made after 14 and 42 days. RESULTS: Histological changes were observed by light microscopy; less intense inflammatory reaction in the irradiated group was found when compared to the controls. Only the irradiated group of 42 days exhibited an area associated with reactional dentinogenesis. After immunohistochemical analysis by the streptoavidin-biotin complex (SABC) method, the expression of Col III, TN, and FN was greater in the irradiated groups. CONCLUSION: Our results suggest that a GaAlAs laser with energy density of 4 J/cm2 and wavelength of 670 nm caused biomodulation in pulp cells and expression of collagen, but not collagen of the extracellular matrix, after preparation of a cavity.

In vivo study of the Nd:YAP laser in persistent periapical lesion.

OBJECTIVE: The aim of this study was to evaluate the therapeutic effect of ND:YAP laser in persistent lesions through signs and symptoms such as the presence of fistulas and pain, respectively. BACKGROUND DATA: Periapical lesions with bacterial invasion, giving origin to bacterial infections, appear many times during the endodontic treatment, which aims at preparing and disinfecting the root canal system, in canals with mortified pulp. The endodontic treatment aim at eliminating infections and reinfection prevention; however, sometimes re-treatment is necessary, and it can be complemented with paraendodontic surgery due to reinfection, which can also persist. METHODS: Our study group consisted of six clinical cases (endodontic treatment), with the introduction of a 300-microm optic fiber through the fistula channel, where three applications were carried out with an interval of 15 sec, each with a discharge of 300 mJ of energy and frequency of 30 Hz. RESULTS: After a 7-day interval, the signs and symptoms were absent, even after a follow-up of 18 months. It was also observed, through a microbiological study, the decrease of the local microbiota. CONCLUSIONS: Our results supported the use of Nd:YAP laser, in part since it created an unfavorable environment for the continuing development of microorganisms.

Effect of low-intensity laser irradiation on the process of bone repair.

The effect of low-intensity laser (GaAsAl) irradiation on bone repair in the femurs of mice was investigated. An experimental model of hole injury with surgery drills was used in 20 mouse femurs followed by a study of the effect of low-energy laser irradiation on bone repair. The experimental model was divided into two groups. The first (10 left femurs) received laser irradiation immediately after injury and was followed for different time intervals (24, 48, and 72 h). The right femurs (control group) underwent hole injury but no laser irradiation. The rats were sacrificed after 14 days and the results were analyzed using a quantitative histometrical method. The Mann-Whitney test was used to perform the statistical analysis. Histometrical analysis revealed a more rapid accumulation of reparative new bone in the hole injury of the laser-irradiated legs. We conclude that GaAsAl laser irradiation after injury was effective on bone repair when compared to results in the control group.

Efficiency of laser therapy applied in labial traumatism of patients with spastic cerebral palsy.

The aim of this study was to report the effectiveness of laser therapy applied to traumatic labial injury of patients with spastic cerebral palsy. We report two cases of patients with internal mucosa and lower lip traumatism caused by oral reflex automatism with spastic tonic bite and lower lip interposition. One patient presented extensive lower lip ulceration, loss of tissue, crusty and hemorrhagic areas, with increasing pain and spasticity. The other patient presented local congestion signs, extremely enlarged tissue growth and increased labial volume. Laser therapy was applied to all injured areas, with a low-potency diode InGaAlP laser [685 nm Quasar (Dentoflex), 190 J/ cm2, with a 24-h interval between the first and second administration, and a 7-day interval between the two subsequent ones. At first re-evaluation, 24 h later, there was a striking reduction in inflammation, a decrease in vascular congestion, and a reduction of the ulcerated area with spasticity and pain reduction. At the 14-day re-evaluation, significant clinical differences in the advanced healing process were seen. Low-intensity laser showed to be effective in traumatic soft tissue treatment in cerebral palsy patients by accelerating the healing process, reducing secondary contamination, promoting analgesia; thus, it can be an important tool in the treatment of these patients.
