Ridge preservation of compromised extraction sockets applying a soft cortical membrane: A canine proof-of-principle evaluation.

OBJECTIVES: To explore whether placement of a soft cortical membrane can restore and regenerate the original alveolar ridge contour in deficient sockets. MATERIALS AND METHODS: One Beagle dog was used in this proof-of-principle evaluation. In a first intervention, a standardized buccal dehiscence defect was artificially created at the distal roots of the 3rd and 4th mandibular premolars. Four weeks later, following endodontic treatment of the mesial roots, teeth were hemisected and the distal roots were extracted without raising a flap. A cortical membrane (Lamina®, Osteobiol) was placed outside of the bony envelope of the extraction socket to rebuild the buccal bone contour. Afterwards, sockets were filled with a collagen-modified porcine bone graft material (Gen-Os®, Osteobiol) to the level of the surrounding bone height. The socket orifice was closed with a porcine dermal matrix (Derma®). After four months, block specimens containing the socket-sites and remaining roots were retrieved, histologically processed and analyzed. RESULTS: Surgery and post-operative healing were uneventful. Histologically, bone formation under the membrane was found, i.e. bony protrusions and ossicles by osteoblasts could be identified. Concomitantly, the membrane showed clear signs of degradation. Bone substitute was well integrated in newly formed bone and resorption of particles was found. CONCLUSION: Three major observations were made in the present proof-of-principle study: (i) regeneration of a compromised socket seems possible when applying the presented approach, (ii) the soft cortical membrane was sufficiently stable to allow for the establishment of the contour and to inhibit soft tissue invasion and (iii) the applied xenogenic graft material was undergoing remodelling processes while allowing adequate bone regeneration.

Odontología deportiva y prevención de trauma dentoalveolar / Sports dentistry and prevention of dentoalveolar traumas

La odontología deportiva es la rama de la medicina deportiva que se ocupa de la prevención y el tratamiento de las lesiones bucodentales y las enfermedades orales asociadas al deporte y el ejercicio. Por lo que se hace necesario la intervención de profesionales de la salud bucodental para hacer evaluaciones del deportista y el deporte que practica para ver los riesgos que puede tener de desarrollar y sufrir lesiones bucodentales como traumas dentoalveolares y lesiones no cariosas. Y de este modo realizar las recomendaciones a cada paciente que practica deporte, de los elementos que deben usar como equipamiento bucodental para evitar o reducir el daño dentoalveolar (AU)

Sports dentistry is the branch of sports medicine that deals with the prevention and treatment of oral injuries and oral diseases associated with sports and exercise. Therefore it is necessary the intervention of oral health professionals to make evaluations of the athlete and the sport he practices to see the risks that may have to develop and suffer oral injuries such as dentoalveolar trauma and non-carious lesions. And in this way make the recommendations to each patient who practices sports, of the elements that should be used as oral equipment to avoid or reduce dentoalveolar damage (AU)

Nasal septal abscess caused by anaerobic bacteria of oral flora.

Although nasal septal abscess (NSA) was formerly common, it has become rare since the development of antibiotics. NSA, if left untreated, can lead to intracranial complications such as meningitis and eventually result in saddle-nose deformity. NSA often occurs after injury, and indigenous skin bacteria such as Staphylococcus aureus are frequently detected. We treated a patient who had injured the upper alveolus in a fall on the stairs and developed NSA two weeks later. Anaerobic bacteria, including Veillonella parvula and Peptostreptococcus sp., were detected. Symptoms were relieved by needle and incisional drainage. Our patient represents a very rare case of NSA in terms of the cause of onset and the detected bacteria. Early drainage can result in good outcomes.

OBJECTIVES: To characterize consultations for odontogenic abscesses at the dental and maxillofacial unit of the public emergency hospital in Santiago, Chile. METHODOLOGY: descriptive study, involving consecutive sampling of patients with diagnosis of odontogenic abscess, conducted between august and september 2016. descriptive statistics were performed to determine the frequency of diagnosis, affected tooth, sex and need for hospitalization. RESULTS: odontogenic abscesses accounted for 6.3 percent (n=414) of a total of 6,535 consultations. males represented 59 percent; 42 percent of odontogenic abscesses presented in molars and maxillary premolars. the vestibular space was the most frequently affected anatomical space (50 percent), associated in 53 percent of the cases to submucosal abscesses. ninety-eight per cent of patients were successfully treated on an outpatient basis, 2 percent required hospitalization, mainly associated to abscesses involving the deep submandibular space. CONCLUSION: odontogenic abscesses account for a low percentage of dental emergencies at the public emergency hospital in Santiago, Chile. most cases receive outpatient treatment.

Diagnosis of alveolar and root fractures: an in vitro study comparing CBCT imaging with periapical radiographs.

OBJECTIVE: To compare periapical radiograph (PR) and cone-beam computed tomography (CBCT) in the diagnosis of alveolar and root fractures. MATERIAL AND METHODS: Sixty incisor teeth (20 higid and 40 with root fracture) from dogs were inserted in 60 anterior alveolar sockets (40 higid and 20 with alveolar fracture) of 15 macerated canine maxillae. Each fractured socket had a root fractured tooth inserted in it. Afterwards, each maxilla was submitted to PR in two different vertical angulation incidences, and to CBCT imaging with a small field of view (FOV) and high-definition protocol. Images were randomized and posteriorly analyzed by two oral and maxillofacial radiologists two times, with a two-week interval between observations. RESULTS: Sensitivity and specificity values were good for root fractures for PR and CBCT. For alveolar fractures, sensitivity ranged from 0.10 to 0.90 for PR and from 0.50 to 0.65 for CBCT. Specificity for alveolar fractures showed lower results than for root fractures for PR and CBCT. Areas under the ROC curve showed good results for both PR and CBCT for root fractures. However, results were fair for both PR and CBCT for alveolar fractures. When submitted to repeated measures ANOVA tests, there was a statistically significant difference between PR and CBCT for root fractures. Root fracture intraobserver agreement ranged from 0.90 to 0.93, and alveolar fracture intraobserver agreement ranged from 0.30 to 0.57. Interobserver agreement results were substantial for root fractures and poor/fair for alveolar fractures (0.11 for PR and 0.30 for CBCT). CONCLUSION: Periapical radiograph with two different vertical angulations may be considered an accurate method to detect root fractures. However, PR showed poorer results than CBCT for the diagnosis of alveolar fractures. When no fractures are diagnosed in PR and the patient describes pain symptoms, the subsequent exam of choice is CBCT.

[Histomorphometric evaluation of ridge preservation after molar tooth extraction].

OBJECTIVE: To evaluate bone formation in human extraction sockets with absorbed surrounding walls augmented with Bio-Oss and Bio-Gide after a 6-month healing period by histologic and histomorphometric analyses. METHODS: Six fresh molar tooth extraction sockets in 6 patients who required periodontally compromised moral tooth extraction were included in this study. The six fresh extraction sockets were grafted with Bio-Oss particle covered with Bio-Gide. The 2.8 mm×6.0 mm cylindric bone specimens were taken from the graft sites with aid of stent 6 months after the surgery. Histologic and histomorphometric analyses were performed. RESULTS: The histological results showed Bio-Oss particles were easily distinguished from the newly formed bone, small amounts of new bone were formed among the Bio-Oss particles, large amounts of connective tissue were found. Intimate contact between the newly formed bone and the small part of Bio-Oss particles was present. All the biopsy cylinders measurement demonstrated a high inter-individual variability in the percentage of the bone, connective tissues and Bio-Oss particles. The new bone occupied 11.54% (0-28.40%) of the total area; the connective tissues were 53.42% (34.08%-74.59%) and the Bio-Oss particles were 35.04% (13.92%-50.87%). The percentage of the particles, which were in contact with bone tissues, amounted to 20.13% (0-48.50%). CONCLUSION: Sites grafted with Bio-Oss particles covered with Bio-Gide were comprised of connective tissues and small amounts of newly formed bone surrounding the graft particles.

Relação entre características peculiares em radiografia panorâmica e a incidência de alteração sensorial do nervo alveolar inferior após cirurgia de remoção de terceiros molares inferiores / The relationship between peculiar features in panoramic radiograph and the incidence of sensory disturbance of the alveolar nerve after inferior third molar extraction

Há um crescente interesse na Odontologia em determinar a probabilidade e prevenir que ocorram alterações sensoriais no feixe vásculo-nervoso alveolar inferior (FVNAI) durante a remoção cirúrgica de terceiros molares inferiores. Este estudo tem por objetivo avaliar e descrever as observações encontradas na literatura sobre os sinais radiográficos correlacionados à proximidade das raízes dos terceiros molares inferiores com o FVNAI. A pesquisa bibliográfica foi realizada utilizando o banco de dados MEDLINE, via PubMed. Somente foram incluídos artigos escritos na língua inglesa. O resumo de todos os artigos da busca eletrônica foi avaliado de acordo com a pertinência para os estudos. De acordo com a revisão realizada, os sinais radiográficos mais associados com alterações sensoriais pós-exodontia dos terceiros molares inferiores foram escurecimento da raiz, interrupção da linha branca e desvio do canal. A verdadeira relação entre os terceiros molares inferiores e o canal mandibular aumenta o risco de lesão do nervo alveolar inferior e uma avaliação precisa deste relacionamento é essencial para evitar os riscos da cirurgia. Sendo assim, os cirurgiões devem estar cientes das limitações dos marcadores radiográficos das panorâmicas e devem considerar a imagem mais detalhada em casos específicos em que mais de um marcador radiográfico esteja presente...

There is a growing interest in determining the probability and preventing alterations in sensory-vascular bundle of the inferior alveolar nerve (SVBIAN) during surgical removal of lower third molars. This study aimed to evaluate and describe the observations in the literature about the correlation between radiographic signs and the proximity of the third molar roots with SVBIAN. A literature search was performed using the MEDLINE database via PubMed. Only articles written in English were included. The summary of all articles were evaluated according to relevance of the studies. According to the performed review, the radiographic signs most related with sensory changes after extraction of lower third molars were darkening of the root, interruption of the white line and diversion channel. The true relationship between third molars and mandibular canal increases the risk of injury to the inferior alveolar nerve, and an accurate assessment of this relationship is essential to avoid the risks related to this surgery. Therefore, surgeons should be aware of the limitations of the panoramic radiographic markers, and should consider more detailed image in specific cases where more than one radiographic marker is present...

Preparation and biocompatibility evaluation of bioactive glass-forsterite nanocomposite powder for oral bone defects treatment applications.

Bone defects which emerge around dental implants are often seen when implants are placed in areas with insufficient alveolar bone, in extraction sockets, or around failing implants. Bone regeneration in above-mentioned defects using of bone grafts or bone substitutes may cure the long-term prognoses of dental implants. Biocompatibility, bioactivity and osteogenic properties are key factors affecting the applications of a bone substitute. This study was aimed at preparation, characterization, biocompatibility and bioactivity evaluation of the bioactive glass-forsterite nanocomposite powder as a desired candidate for oral bone defect treatments. Nanocomposite powders containing 58S bioactive glass and different amounts of forsterite nanopowder were synthesized in situ by sol-gel technique. Characterization of the prepared nanocomposite powders and their cytotoxicity assessment was performed via MTT test. Bioactivity assessment was done by immersing the prepared powder in the simulated body fluid (SBF). Results showed that nanocomposite powders containing forsterite with crystallite size of 20-50nm were successfully fabricated by calcination at 600°C. The prepared bioactive glass-forsterite nanocomposite powders revealed high in vitro biocompatibility; besides, the nanocomposite containing 20wt.% forsterite showed a substantial increase in the cell viability compared with control groups. During immersion in SBF, the formation of apatite layer confirmed the bioactivity of bioactive glass-forsterite nanocomposite powders. According to the results, the fabricated nanocomposite powders can be introduced as a promising candidate for oral bone imperfection treatments and hard tissue mend.

Classification and Epidemiology of Traumatic Dentoalveolar Injuries in Dogs and Cats: 959 Injuries in 660 Patient Visits (2004-2012).

The objective of this study was to determine the epidemiology of traumatic dentoalveolar injuries (TDI) in dogs and cats and to evaluate the applicability of a human classification system for TDI in dogs and cats. All patients diagnosed with a TDI were identified from the University of Wisconsin-Madison School of Veterinary Medicine Dentistry and Oral Surgery Service case log and the hospital patient processing software. The study population consisted of 621 dogs and cats, in a total of 660 patient visits from 2004 to 2012, admitted for oral treatment and subsequently diagnosed with at least one TDI Medical records including diagnostic imaging studies were reviewed to group the injury according to a classification system used in humans for TDI. Patient signalment, tooth injured, and number of injuries per patient were recorded and tabulated. The overall prevalence of TDI was 26.2%. The mean +/- SD number of TDI per patient was 1.45 +/- 0.85. All 14 classes of TDI recognized by the classification system utilized in humans were identified, and all (100%) TDI identified in this study were classifiable using this system. Enamel-dentin-pulp fracture was the most common TDI (49.6%). The most commonly injured teeth were the mandibular or maxillary canine teeth (35.5%). The most common age for dogs and cats with TDI were 3-6 years (33.0%) and 7-10 years (31.3%). With a frequency of 1 in 4 animals, TDI are common and represent a significant pet health concern. Most TDI are considered severe and require timely, and sometimes immediate, treatment. The adoption and utilization of a complete classification system, such as the one used in this study, is recommended in order to improve future epidemiological study of TDI in animals.

Root amputation: a new look into an old procedure.

A treatment option for managing furcation invasions is root amputation. Long-term survival of resected molars requires a complete harmony of sequential endodontic, periodontic, restorative and maintenance procedures. The main objective of this article is to provide a concise historical perspective of this procedure and to review available literature regarding its efficacy and limitations. It also illustrates a current modification of the procedure using guided bone regeneration (GBR) and socket preservation to eliminate some of the potential disadvantages of the traditional root amputation procedure.
