Seqüelas em dentes permanentes após trauma nos predecessores decíduos e sua implicação clínica

In regarding to the high prevalence of traumatic dental injuries in primary teeth and the possible disturbances on developing permanent successor germs, an early diagnosis and an adequate establishment of treatment planning are very important to minimize the damage caused by the trauma. Sequelaes can affect the coronal portion (white or yellow-brown discoloration associated or not with enamel hipoplasia, dilacerations of the crown), the root portion (dilaceration, duplication or cessation of root formation) or the whole successor permanent tooth (odontoma sequestration or disturbances of permanent successor eruption). The aim of this study is to make a literature review of the developmental disturbances of permanent teeth followed by traumatic injuries to theirs primary predecessors and to present cases reports to advise the dentists, their patients and parents about the damage that developing permanents teeth can undergo.

Efeito da aPDT na osseointegração de implantes em alvéolos contaminados

Objective: The aim of this study is to evaluate by histometric and immunohistochemistry analysis the effects of antimicrobial photodynamic therapy (aPDT) in alveolar prior to placement of mini-implants in animals with or without induced periodontal disease. Material and method: Thirty-two rats were used. Periodontal disease (PD) was induced by ligature in the lower left first molar. After 7 days of PD evolution, it was performed removal of the ligature and extraction of the left lower first molars in all animals. Thus, animals were divided into 2 groups (n=16) according to the treatments in the dental alveolus before immediate implant installation: MD (control) : mechanical debridement (MD), irrigation with 1 ml of saline solution followed by implant installation; aPDT- MD, irrigation with 1 ml of Toluidine Blue-O and low intensity laser (LLLT) and implant installation. Eight animals from each group were euthanized at 15 and 30 days after the installation of mini-implants. Specimens were processed for histologic, immunohistochemical and histometric analysis. The histometric data were processed for statistical analysis (Kruskall-Wallis and Dunn test; p <0.05). Result: In treatment analysis, results indicated that there was a greater BIC in implants installed in uncontaminated alveolus treated with a PDT ( p<0,05) and greater imuno-reactivity to OPG in bone issue treated with aPDT. Conclusion: The aPDT proved to be effective in bone loss control in no contaminated area and it has increased the bone loss and metabolic activity in alveolus irradiated prior to implant installation.

Desgaste superficial do esmalte dental após microabrasão in vitro

The aim of this study was to investigate the enamel wear permanent teeth after plastic stick or low speed rubber cup microabrasion. Ten permanent molars were selected to evaluate enamel wear which were sectioned into mesial and distal halves. Each half of the molars was randomly assigned to one of two experimental groups (n = 10) according to the enamel microabrasion technique: plastic stick (GE) or rubber cup (GT). In both the groups, the enamel was submitted to 10 applications of an abrasive paste comprised of 35% phosphoric acid and pumice powder. The paste was applied for 20 seconds under a pressure of 30 g using the instrument defined for each group (plastic stick or rubber cup). The specimens were evaluated under a stereomicroscope connected to a computer. The enamel wear no was statistically different between GE and GT, which presented a mean wear of 304.74 µm (21.20%) and 338.35 µm (22.75%). In conclusion, superficial enamel wear was seen for both the groups, independent of the technique used for the accomplishment of the microabrasion.

Limitations of enamel microabrasion technique applied in a pediatric patient: case report

Enamel microabrasion is a non-invasive method that removes intrinsic and superficial defects from teeth aimed to improve dental esthetic with minimal loss of dental tissue. This case presentation describes the attempt for teeth color correction utilizing that conservative technique in a young girl whose upper central incisor presented an opaque white stain. Scanning electron microscopy (SEM) was conducted in order to illustrate the glasslike luster and a smooth texture of microabraded enamel surface. The correct diagnosis of defect is a difficult task, when consider this conservative approach.
