RESUMO
AIM: The aim of the present study was to determine the success rate after 12 months of follow-up in a series of cases in which chemo-mechanical caries removal (CMCR) was performed with Papacarie(TM), followed by restoration with glass ionomer cement. BACKGROUND: The development of conservative techniques for carious tissue removal and improvements in dental restoration materials have allowed better preservation of dental structures in the treatment of decayed teeth. Chemo-mechanical caries removal (CMCR) is a conservative atraumatic treatment option. Papacarie(TM) is a papain-based material developed to act only on the carious dentin, allowing its easy removal with a blunt curette. CASE REPORT: The study involved a total of 84 deciduous posterior teeth with occlusal dentinal caries. Only teeth without risk of pulp exposure were studied. After a period of 12 months, the restorations were evaluated based on criteria employed in previous studies. The radiographic evaluation revealed resorption and calcification of the affected teeth. The data were submitted to descriptive statistical analysis with the aid of the XLSTAT program. The success rate was 88.1% and 98.8% based on the clinical and radiographic evaluations, respectively. The difference between the success and failure rates was statistically significant (p < 0.0001). CONCLUSION: Papacarie(TM) is an effective product for CMCR on occlusal dentinal tissue in deciduous teeth, demonstrating a high clinical and radiographic success rate after 12 months of follow-up.

O tumor odontogênico queratocístico (TOQ) é uma neoplasia benigna dos ossos gnáticos, que apresenta agressividade local e alta taxa de recorrência. O TOQ é uma lesão intra-óssea, invasiva e destrutiva dos maxilares que apresenta crescimento lento e infiltrativo sendo, geralmente, uma lesão assintomática. A radiografia e a tomografia computadorizada auxiliam no diagnóstico, sendo necessária a biópsia e análise histopatológica para diagnóstico definitivo. Entre as técnicas de tratamento estão a ressecção, a enucleação, a curetagem, a descompressão e a marsupialização. É de suma importância que o cirurgião conheça a neoplasia e a recente classificação da Organização Mundial da Saúde para que, após o diagnóstico, os tratamentos sejam adequadamente escolhidos. Este estudo visou abordar atualidades acerca do TOQ por meio da revisão da literatura.
The keratocystic odontogenic tumor (KOT) is a benign neoplastic lesion of the jaws, disclosing a high local aggressiveness and a high recurrence rate. The KOT is an asymptomatic slow growing tumor of the jaws with an infiltrative, invasive and destructive intraosseous behavior. Radiography and computed tomography images aid the diagnosis but biopsy and histopathology must be carried out to point a definitive diagnosis. The treatment is a surgical procedure. The techniques are resection, enucleation, curettage, decompression and marsupialization. It is paramount that the surgeon knows the lesion features after the recent World Health Organization remarks to perform the best treatment after diagnosis. This study aimed to address updates about KOT through a literature review.

PURPOSE: The aim of this study was to compare the effect of polishing after scaling and root planing on supragingival plaque, calculus formation, and gingival bleeding. MATERIALS AND METHODS: The study was designed as a split-mouth randomised clinical trial. Seventy-six patients were submitted to supragingival scaling on the six mandibular anterior teeth with manual curettes until a smooth surface was achieved. Subsequently, quadrants were randomly selected to be polished (test) or not (control) with a rubber cup and pumice. One, two and three weeks following treatment, a blinded examiner evaluated the visible plaque index, gingival bleeding index and the presence of supragingival calculus on the lingual tooth surfaces. RESULTS: The results showed that unpolished surfaces exhibited higher mean percentages of visible plaque in the third week. No statistically significant differences were observed between unpolished and polished sites related to gingival bleeding. Calculus formation was higher on unpolished sites than on polished sites at 2 and 3 weeks. Dental polishing after supragingival scaling contributed to reducing plaque and calculus formation. CONCLUSIONS: Polishing exerts an inhibitory effect on plaque and calculus formation.

BACKGROUND: The present study aims to compare the performance of minimally invasive non-surgical and surgical approaches for the therapy of intrabony defects. METHODS: Twenty-nine patients who presented with intrabony defects were randomly assigned to: 1) a minimally invasive non-surgical technique (MINST) group, or 2) minimally invasive surgical technique (MIST) group. The chair time of each therapeutic procedure was calculated. The probing depth (PD), position of the gingival margin (PGM) and relative clinical attachment level (RCAL) were evaluated at 3 and 6 months after treatments. The patient perception of discomfort/pain experienced during and after therapy and patient satisfaction regarding treatments were also evaluated. RESULTS: Significant PD reductions, RCAL gains, and no changes in the PGM were obtained at 3 and 6 months in MINST and MIST groups (P <0.05). No differences were observed between groups at any time points (P >0.05). Patient-oriented outcomes did not demonstrate differences between therapeutic approaches (P >0.05). Significant higher chair times were required in the MIST group than in the MINST group (P <0.05). CONCLUSIONS: Minimally invasive non-surgical and surgical approaches were successfully used for the treatment of intrabony defects and achieved periodontal health in association with negligible morbidity and suitable patient satisfaction. However, non-surgical therapeutic modality presented an advantage in terms of a reduction of treatment chair time.

BACKGROUND: Newly formed biofilm after implant debridement may challenge the long-term stability of peri-implant therapy. This in vitro study aimed to assess the roughness and adherence of Streptococcus sanguinis after treatment of smooth and rough titanium surfaces with an erbium-doped:yttrium, aluminum, and garnet (Er:YAG) laser, metal and plastic curets, and an air-powder abrasive system. METHODS: Forty titanium disks with smooth-machined surfaces and 40 with sand-blasted and acid-etched surfaces were divided into the following treatment groups: Er:YAG laser; plastic curet; metal curet, and air-powder abrasive system. The surface roughness (roughness average [Ra]) before and after treatments was determined using a profilometer. S. sanguinis (American Type Culture Collection 10556) was grown on treated and untreated specimens, and the amounts of retained bacteria on the surfaces were measured by the culture method. Rough and smooth surfaces with and without a suspension of S. sanguinis were also analyzed using scanning electron microscopy (SEM). RESULTS: For smooth surfaces, the roughest surfaces were produced by metal curets (repeated-measures analysis of variance [ANOVA] and Tukey test; P <0.05). The rough-surface profile was not altered by any of the treatments (repeated-measures ANOVA; P >0.05). Rough surfaces treated with metal curets and air-powder abrasion showed the lowest level of bacterial adhesion (two-way ANOVA and Tukey test; P <0.05). SEM analysis revealed distinct surface profiles produced by all devices. CONCLUSIONS: Metal curets are not recommended for smooth titanium surface debridement due to severe texture alteration. Rough surfaces treated with a metal curet and the air-powder abrasive system were less susceptible to bacterial adhesion, probably due to texture modification and the presence of abrasive deposits.

This study evaluated, in vitro, fibroblast attachment to periodontally involved root surfaces which were either root planed or acid/chelated by different agents. Specimens were divided into 3 groups of 12 specimens each. The root surfaces were root planed with a Gracey 7/8 curette, an EMS or an Amdent piezo-electric scaler and treated with saline, citric acid, tetracycline hydrochloride or EDTA to produce different surface textures. They were then cultured with fibroblasts for 72 h and examined by scanning electron microscopy. There was a significantly greater number of fibroblasts attached to specimens treated with citric acid, tetracycline and EDTA than to those root planed only. Furthermore, fibroblasts were more likely to attach to rough-surfaced than to smooth-surfaced specimens.

Estudos demonstram haver concordância de que a causa fundamental da necrose avascular da cabeça do fêmur seria a interrupçäo da irrigaçäo da cabeça femoral, embora ainda existam discussöes sobre a etiologia e o tratamento adequado. A curetagem da necrose mais enxerto ósseo tem sido muito estudada, dentre os tratamentos que näo empregam material sintético, pois, além de manter o próprio osso, näo impede futuras intervençöes. A utilizaçäo desse método na prática apresentou dificuldades, tais como a necessidade de grande abertura no colo femoral para curetagem da cabeça, causando destruiçäo de grande quantidade de vasos e problemas na retirada do osso ebúrneo com curetas convencionais. Baseado nesses elementos, desenvolveu-se um instrumental para realizaçäo de ampla curetagem da cabeça, independente da textura óssea, e, conseqüetemente, com menor destruiçäo do colo femoral
