Kinesio taping use to reduce pain and edema after third molar extraction surgery: A randomized controlled split-mouth study.

OBJECTIVE: Evaluating Kinesio Taping (KT) use to reduce pain and edema in individuals subjected to surgical extraction of impacted mandibular third molars. MATERIALS AND METHODS: Thirteen individuals (5 men and 8 women, mean age: 23.25 years) were subjected to mutual extraction of two mandibular third molars based on the same surgical protocol and pharmacological approach. All individuals were subjected to kinesio taping application on one side of patients' face (test group - KT), in the immediate postoperative period. The other side of the face was not subjected to KT application, and it was used as control (No KT). An examiner assessed individuals' pain and edema based on the visual analog scale (VAS) and on the Todorovic-Markovic method, respectively, at the preoperative, immediate postoperative, and second and fifth postoperative days. Statistical analysis was based on the Scheirer-Ray-Hare test. RESULTS: Edema (48 h and 120 h after surgery) and pain intensity (24 h, 48 h and 120 h after surgery) were lower on the KT side (p < 0.05). Moreover, edema and pain intensity fully reduced on the KT side 120 h after surgery (p < 0.05). CONCLUSION: Kinesio taping adopted in the current study was effective in reducing edema and postoperative pain in patients subjected to oral surgery. CLINICAL RELEVANCE: KT enables patients to experience a more comfortable postoperative period and helps improving their quality of life.

Oral Hygiene of Patients with Cancer in the Intensive Care Unit / Higiene Bucal de Pacientes com Câncer em Unidade de Terapia Intensiva

Dental care in Intensive Care Units - ICU, plays an important role in maintaining the health and well-being of critically ill patients. Although infection is a frequent manifestation in Intensive Care Unit (ICU) patients, the risk of infection by the oral cavity should also be considered. The immune response of this patient may be compromised, and consequently latent infections may intensify. The mouth is considered an ideal microbial incubator because of its characteristic of pH, presence of nutrients and hard surfaces. The relationship between periodontal disease and systemic conditions, including lung infections, is being explored. This study had the purpose of evaluating the odontology conditions in hospitalized patients with cancer in an intensive care unit at the Cancer Hospital of Londrina - Paraná, Brasil, quantifying the oral microbiota and evaluating bacterial resistance. Inclusion criteria involved critical patients of both sexes, two male and two female, ranging from 40 to 80 years old, submitted to mechanical endotracheal breathing. The presence of visible biofilm and xerostomia were the most prevalent. The results obtained are three patients who presented Klebsiella pneumoniae producer of Carbapenemase, due to the oral hygiene deficiency in patients hospitalized in the ICU, which are responsible for major systemic complications, increasing hospitalization time.(AU).

O atendimento odontológico nas Unidades de Terapia Intensiva - UTI, tem papel importante na manutenção da saúde e bem-estar dos pacientes criticamente doentes. Embora a infecção seja uma manifestação frequente em pacientes de Unidade de Terapia Intensiva (UTI), o risco de infecção pela cavidade bucal também deve ser considerado. A resposta imune desse paciente pode ser comprometida e consequentemente infecções latentes podem intensificar. A boca é considerada uma incubadora microbiana ideal devido à sua característica de pH, presença de nutrientes e superfícies duras. A relação entre doença periodontal e condições sistêmicas, incluindo infecções pulmonares, está sendo explorada. Este estudo teve a finalidade de avaliar as condições odontológicas em pacientes com câncer internados em unidade de terapia intensiva do Hospital do Câncer de Londrina estado do Paraná, Brasil, quantificando a microbiota bucal e avaliando a resistência bacteriana. Os critérios de Inclusão envolveram pacientes críticos de ambos sexos, dois masculinos e dois femininos com idade variando dos 40 aos 80 anos, submetidos à respiração mecânica endotraqueal. A presença de biofilme visível e xerostomia foram a alteração mais prevalente. Nos resultados obtidos encontrou-se três pacientes que apresentaram Klebsiella pneumoniae produtoras de Carbapenemase, pela deficiência de higienização bucal nos pacientes internados na UTI, que são responsáveis por grandes complicações sistêmicas, aumentando o tempo de internamento.(AU).

Evaluation of the presence of VEGF, BMP2 and CBFA1 proteins in autogenous bone graft: histometric and immunohistochemical analysis.

AIMS: The purpose of this study was to evaluate the expression of proteins that participate in the osteoinduction stage (VEGF, BMP2 and CBFA1) of the process of bone regeneration of defects created in rat calvariae and filled with autogenous bone block grafts. MATERIALS AND METHODS: 10 adult male rats (Rattus norvegicus albinus, Wistar) were used, who received two bone defects measuring 5 mm each in the calvariae. The bone defects constituted two experimental groups (n = 10): Control Group (CONT) (defects filled with a coagulum); Graft Group (GR) (defects filled with autogenous bone removed from the contralateral defect). The animals were submitted to euthanasia at 7 and 30 days post-operatively. RESULTS: Quantitative analysis demonstrated significantly greater bone formation in Group GR, but the presence of the studied proteins was significantly greater in the CONT Group in both time intervals of observation. CONCLUSION: It was not possible in this study in cortical bone block groups to detect the osteoinductive proteins in a significant amount during the repair process.

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 Araçatuba, 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.

Bone regeneration in surgically created defects filled with autogenous bone: an epifluorescence microscopy analysis in rats.

UNLABELLED: Although the search for the ideal bone substitute has been the focus of a large number of studies, autogenous bone is still the gold standard for the filling of defects caused by pathologies and traumas, and mainly, for alveolar ridge reconstruction, allowing the titanium implants installation. OBJECTIVES: The aim of this study was to evaluate the dynamics of autogenous bone graft incorporation process to surgically created defects in rat calvaria, using epifluorescence microscopy. MATERIAL AND METHODS: Five adult male rats weighing 200-300 g were used. The animals received two 5-mm-diameter bone defects bilaterally in each parietal bone with a trephine bur under general anesthesia. Two groups of defects were formed: a control group (n=5), in which the defects were filled with blood clot, and a graft group (n=5), in which the defects were filled with autogenous bone block, removed from the contralateral defect. The fluorochromes calcein and alizarin were applied at the 7th and 30th postoperative days, respectively. The animals were killed at 35 days. RESULTS: The mineralization process was more intense in the graft group (32.09%) and occurred mainly between 7 and 30 days, the period labeled by calcein (24.66%). CONCLUSIONS: The fluorochromes showed to be appropriate to label mineralization areas. The interfacial areas between fluorochrome labels are important sources of information about the bone regeneration dynamics.

Management of a complicated crown-root fracture using adhesive fragment reattachment and orthodontic extrusion.

Dental trauma is more common in young patients and its sequelae may impair the establishment and accomplishment of an adequate treatment plan. This paper reports a case of complicated crown-root fracture in a young adult that was treated using adhesive tooth fragment reattachment and orthodontic root extrusion. Considering the time elapsed to follow up, the fracture extension, the amount of remaining root portion and the patient's low socioeconomic status, the treatment approach proposed for this case provided good functional and aesthetic outcomes. Clinical and radiographic results after 2 years were successful. This case report demonstrates the importance of establishing a multidisciplinary approach for a successful dental trauma management.
