To evaluate the influence of bioactive glass and photobiomodulation therapy (PBMT) in calvarial bone repair process in rats submitted to zoledronic acid therapy. Methods: Twenty-four rats were selected and treated with the dose of 0.035 mg/kg of zoledronic acid every two weeks, totalizing eight weeks, to induce osteonecrosis. After the drug therapy, surgical procedure was performed to create 5-mm diameter parietal bone defects in the calvarial region. The rats were then randomly assigned to groups according to the following treatments: AZC: control group, treated with blood clot;
Osteogenesis imperfecta (OI) is a disease characterized by decreased bone mineral density, causing susceptibility to bone fractures by mild trauma and bone deformities. The aim of this study was to describe an osteogenesis imperfecta type III clinical case, its craniofacial and oral changes as well as its atypical radiographic findings. An eighteen-year-old, male patient diagnosed with osteogenesis imperfecta type III was referred for dental evaluation; the clinical examination showed the craniofacial and oral changes of the disease such as triangular face, class III malocclusion, anterior open bite and posterior crossbite, dentinogenesis imperfecta presenting amber discoloration. The radiographic examination revealed teeth with pulp chamber obliteration and root canals, however unusual findings were also observed such as: bilateral increase of the mandibular canals and preservation of the pulp chamber and third molar root canals. Our findings show that is essential an adequate knowledge of anatomy, a careful anamnestic evaluation and a complete radiological evaluation of the patient with OI. Key words: Dental anomalies, developmental disability, rare disorders.
Sialolithiasis is a common disease that affects the major salivary glands, which is characterized by obstruction of the gland itself or its excretory duct due to the formation of a sialolith, resulting in decreased salivary flow. It mainly affects the submandibular glands (80%-90%), probably because it has a long duct that surrounds the mylohyoid muscle and emerges against gravity through the Wharton's duct. The size of the salivary calculus can vary from below 1 millimeter (mm) to a few centimeters in diameter, where most stay below 10 mm. Only 7% are greater than 15 mm and these are classified as giant calculi. This report presents a case of asymptomatic giant sialolith (approximately 60 mm in diameter) located in the duct of the right submandibular gland, with 20 years of evolution. The treatment of choice was the surgical removal of the sialolith (calculus) through the salivary duct with maintenance of the gland. Although the individual did not present complaints related to the presence of the giant calculi, its removal had a great impact on their quality of life, since a significant respiratory improvement was reported by the individual. The major difference reported was better sleep quality.
Purpose:This study aimed to quantify, using cone-beam computed tomography (CBCT) in patients who underwent a mandibular advancement surgery associated with genioplasty, three-dimensional changes in airway space and to evaluate whether these changes differ between men and women.Materials and Methods:Preoperative and 8-month postoperative CBCT scans of 38 patients aged 18–45 years of either sex and any ethnicity who underwent mandibular advancement surgery associated with genioplasty were analyzed using the Xoran software (Xoran Technologies, Ann Arbor, MI, USA). The linear distances gonion-gnathion (Go-Gn) and condylion-menton (Co-Me) were obtained. Airway volume was measured using the Dolphin Imaging software, version 11.0. Then, data were tabulated and analyzed using Student's t-test.Results:Mean patient age was 30.3 years; 39.47% were men and 60.63% were women. The mean Go-Gn distance was 72.05 mm before surgery and 78.56 mm after surgery, with a mean gain of 6.51 mm. The mean Co-Me distance was 113.47 mm before surgery and 119.89 mm after surgery, with a mean increase of 6.42 mm. Both differences were statistically significant. The mean volume of airway space was 17,272.92 mm3 before surgery and 24,173.74 mm3 after surgery, with a statistically significant mean increase of 6900.82 mm3. There was no statistically significant difference in mean volumetric gain between men (7566.69 mm3) and women (7456.69 mm3).Conclusion:Mandibular advancement surgery results in significant increase of airway space, and there is no difference in airway volume between men and women.
This clinical report describes the implant rehabilitation for the treatment of pathological roots resorption due to inadequate orthodontic movement in prosthetic space reduced by means of load and immediate implants, computer-guided surgery and use of the own tooth crown in a 21-year-old-patient. The atraumatic exodontics of the right and left upper lateral incisors was performed, and then immediate placement of osseointegrated implants using the computer guided surgery technique. The crown teeth itself was used in the immediate aesthetic and functional rehabilitation. Completion of the treatment resulted in a functional and aesthetic successful outcome and a 27 months follow-up presented uneventful. The procedures included in this complex rehabilitation treatment in the esthetic zone were appropriate and essential for the maintenance of the soft and hard tissues contour and thickness ensuring the excellence in rehabilitation.
This study presents the case of a patient who required antrostomy under general anesthesia to treat a sinus lift complication. The patient was a 43-year-old woman with no systemic abnormalities, who underwent maxillary sinus lift surgery associated with mineralized bovine bone graft. The Schneiderian membrane was perforated during the procedure and the rupture was treated with collagen membranes to close the wound and contain the biomaterial, preventing its dispersion. The patient developed a maxillary sinus infection seven days after the surgery. This infection was initially treated with 875 mg of amoxicillin combined with 125 mg of clavulanic acid. Although the initial infection did not worsen, the patient developed maxillary sinusitis. Thirty days after the onset of the initial infection, the patient underwent an intraoral surgery under local anesthesia to remove the biomaterial and clean the sinus cavity. Despite this procedure, maxillary ostial patency was still compromised and antrostomy was performed endoscopically in a hospital setting under general anesthesia. This procedure resolved the sinus infection. Then, 12 months after hospitalization, the patient was treated with another sinus graft surgery without postoperative complications. The treatment of sinus infections due to graft surgery may require early and active intervention with antibiotics, graft removal, and antrostomy to prevent major complications.
Objetivo: Relatar o caso de extensa perda tecidual traumática do lábio por auto mordida após bloqueio do nervo alveolar inferior para exodontia de terceiro molar inferior incluso. Detalhamentos de Caso: Paciente gênero feminino, 20 anos de idade, leucoderma, sem alterações sistêmicas e psicológicas, compareceu à clínica para extração do elemento dentário 48 incluso. A paciente foi submetida à anestesia pterigomandibular sem intercorrências. Após o procedimento a paciente foi para sua casa ainda com o lábio anestesiado e acabou dormindo. Ao acordar notou que estava com o rosto e com a blusa de sangue, e ao olhar no espelho observou que havia perdido parte do lábio inferior e que provavelmente teria mastigado e engolido uma vez que ainda estava sob efeito da anestesia. A paciente procurou o serviço do Hospital onde foi submetida a um procedimento de cirúrgico pela equipe de cirurgia bucomaxilofacial e cirurgia plástica sob anestesia geral. Considerações finais: é de suma importância a explicação do cirurgião sobre o pós-operatório das cirurgias, sobre os cuidados com a anestesia local, o tempo de efeito de duração droga e os efeitos que ela pode causar enquanto se aguarda metabolização completa da solução em questão.
