Dental Implants in Patients With Osteoporosis: A Clinical Reality?

Osteoporosis is a systemic disorder characterized by generalized decrease in bone mineral density. Dental implantology is a specialty with high predictability when both quantity and quality of the bone are respected. Therefore, the diagnosis and the implant treatment in patients with osteoporosis are important. In the current study, a literature review about osteoporosis and dental implant therapy was conducted. PubMed, Cochrane, ISI, Dentistry Oral Science, SciELO, and Bireme databases were consulted over the last 20 years. English- and Portuguese-language articles were included in this revision. Some authors stated that the osteoporotic bone is similar to the proposed model of bone type IV. Randomized clinical studies reported implant failure in patients with osteoporosis after menopause. Studies that contraindicate the use of implants in patients with osteoporosis infer that the impaired bone metabolism led to reduction of bone healing around the implants. Nevertheless, other authors believe that the presence of osteoporosis is not a definitive condition to contraindicate the therapy with dental implants. In these cases, the dentist should perform a proper treatment planning, modifying the implant geometry, and use larger implant diameter and with surface treatment. Thus, osteoporosis is not a contraindication for implant surgery because an accurate analysis of bone quality by means tomography is performed.

Foreign Body in Preauricular Region

Foreign bodies, although they are often found throughout the body, to a lesser degree in the face, still constitute a diagnostic challenge for the trauma surgeon. Its removal means danger of damaging important facial anatomic structures, even if its exact position from the image data was known. So, the objective is to describe a clinical report of a patient (42 years of age, male sex) who experienced falling to the ground, attended by the Department of Surgery and Traumatology Bucco-Maxillo-Facial Surgery, Faculty of Dentistry of Aracatuba, São Paulo State University, and 2 days after the trauma, he reported difficulty in mouth opening and pain. After clinical evaluation, we observed the presence of injury in the left preauricular region already in the process of healing. During the intraoral physical examination, a limitation of the mouth opening was noted. Radiographic posteroanterior and profile of the face showed 2 radiopaque foreign bodies in the left side, lying apparently at the region of the mandibular condylar process. Under local anesthesia, foreign body removal was carried from there with access to it through the preexisting facial injury. Further clinical examinations showed an improvement in mouth opening, absence of pain complaints, and/or functional complaints.

Comparative Analysis of 2-Flap Designs for Extraction of Mandibular Third Molar

Objective: The objective of the study was to analyze 2-flap designs for surgical extraction of third molar, evaluating the periodontal status of the second lower molar.Study Design: Forty-five lower third molars were extracted from 24 patients. In 23 teeth, a vertical incision to the mandibular ramus was used (technique A), whereas 22 teeth were submitted to classic L-shaped flap (technique B) with controls at 60 and 90 days postoperatively.Results: Pearson correlation coefficient analysis showed a significant correlation only between immediate preoperative probing depth variables from techniques A and B in the studied surfaces. Statistical significances in the preoperative (vestibular) and postoperative day 60 (distovestibular and vestibular) were noted. In contrast, Student t-test showed no statistical difference in probing depths between preoperative and postoperative values, as well as no statistically significant difference regarding the type of incision alone.Conclusions: Technique A allowed a less traumatic surgery, guaranteeing a more comfortable postoperative period.

Sialolithiasis of the Submandibular Gland

Sialolithiasis of the salivary gland is a benign pathology that occurs most frequently in the submandibular gland because of its anatomic features. Depending on the sialolith size and calcification degree, it can be visible in radiographic examinations. Commonly, patients may experience pain and/or edema, when the ducts are obstructed. The authors report the case of sialolithiasis of the submandibular gland in a 42-year-old, female, white-skinned patient, noticed during routine dental examination. Following diagnosis confirmed by clinical and radiographic examinations, the treatment plan consisted of surgery for removal of the calcified mass. The prognosis is often good, and generally there is no recurrence.

Occurrence of tooth injuries in patients treated in hospital environment in the region of Aracatuba, Brazil during a 6-year period

Dental trauma has been considered as a public health problem that affects mainly children and youngsters and due to its impact on the patient's quality of life. This study presents the results of a 6-year survey of the occurrence and characteristics of dental trauma in patients admitted to the Service of Surgery and Oral and Maxillofacial Traumatology of the School of Dentistry of Aracatuba (UNESP, Brazil) after emergency care in hospital facilities in the region of Aracatuba, SP, Brazil. For such purpose, the clinical files of patients treated at the Service between 1999 and 2005 were reviewed. Information regarding gender, age, number of traumatized teeth, etiology and diagnosis of the trauma was collected from the files of patients with tooth injuries and recorded in case report forms specifically designed for this purpose. The results showed that from a total of 4112 patients admitted to the Service within the surveyed period, 266 (6.5%) had tooth injuries (172 males - 64.7%; 94 females - 35.3%). The total number of traumatized teeth was 496. Most patients belonged to the 16-20 year-old age group (20.3%) and the most frequent causes of tooth injuries were bicycle accidents (28.6%), motorcycle accidents (19.2%) and falls (18.8%). Injuries to the periodontal tissues were the most frequent type of tooth injuries (408 teeth; 82.26%), occurring in 118 primary and 290 permanent teeth. Among the injuries to the periodontal tissues, avulsion was the most common (32.86%) (29.41% for primary and 34.0% for permanent teeth), followed by extrusive luxation (19.15%) (25.21% for primary and 17.24% for permanent teeth). In conclusion, in the surveyed population, cases of tooth injuries were more frequent in males aged 16-20 years old due to cyclist accidents with predominance of injuries to the periodontal tissues, in particular, avulsions.

Parâmetros na marcha na paralisia supranuclear progressiva: um estudo de caso

INTRODUÇÃO: Comprometimentos na marcha de pacientes com paralisia supranuclear progressiva (PSP) podem aumentar o risco de quedas durante o andar, especialmente em ambientes complexos. OBJETIVO: Descrever o comportamento locomotor de uma paciente com PSP, nas condições de marcha livre e marcha adaptativa. MATERIAIS E MÉTODOS: Estudo de caso de uma paciente com PSP (71 anos). Para análise cinemática, nas condições de marcha livre, com obstáculo baixo e alto, uma câmera digital registrou uma passada completa da paciente. RESULTADOS: Com o aumento da complexidade do ambiente (marcha livre, obstáculo baixo e alto, respectivamente), foi observada diminuição do comprimento do passo (0,37 ± 0,07; 0,30 ± 0,07; 0,26 ± 0,06 m), do comprimento da passada (0,71 ± 0,11; 0,58 ± 0,15; 0,47 ± 0,07 m) e da velocidade da passada (0,55 ± 0,14; 0,43 ± 0,11; 0,36 ± 0,11 m/s). Aumento progressivo ocorreu na duração do duplo suporte da passada livre (29,47%) para a passada antes do obstáculo alto (41,11%). Observou-se, ainda, ligeira diminuição na distância vertical pé/obstáculo alto (membro/abordagem: 7,18 ± 1,88; e membro/suporte: 8,84 ± 2,57 cm) em relação ao obstáculo baixo (membro de abordagem: 8,86 ± 1,88; e membro de suporte: 11,67 ± 2,09 cm). CONCLUSÃO: A PSP afetou de forma evidente a marcha da paciente. Inflexibilidade para a adaptação da marcha às demandas do ambiente foi observada durante a aproximação e a transposição dos obstáculos, o que pode aumentar o risco de tropeços e quedas.
