Ability of different methods to fill retrograde cavities with MTA.

The Mineral Trioxide Aggregate (MTA) has excellent biological property. However, its consistency makes it difficult to be inserted into retrograde cavities. Objective:To evaluate the ability of different methods to fill retrograde cavities with MTA. Material and methods: Root canals of thirty single-rooted resin teeth were prepared and filled. After the cut of 3 mm short of apical third, retrograde cavities with 3 mm deep were prepared using an ultrasound device and retrotips (CVD, São José dos Campos, SP, Brazil). The retrograde preparation was evaluate by using an operative microscope (D.F. Vasconcellos, São Paulo, SP, Brazil). The teeth were randomly divided into three groups (n = 10), according to the method: 1) condenser (Trinity, São Paulo, SP, Brazil); 2) MTA applicator (Angelus, Londrina, Brazil) + condenser; 3) condenser associated with ultrasound (CVD, São José dos Campos, SP, Brazil). After the filling of retrograde cavities with white MTA (Angelus, Londrina, Brazil), teeth were radiographed using a digital system (Kodak RVG 6000, Rochester, NY, USA). The images were analyzed by UTHSCSA Image Tool 3.0 software. The percentage of filling was calculated by the proportion between the total area of retrograde cavity and the filled area. The radiographic density mean of each third of retrograde cavity filled with MTA was measured by using the histogram tool of the software. The results were submitted to ANOVA and Tukey tests, with 5% of significance. Results: There was no difference in percentage of filling among the groups (p > 0.05) (approximately 85%). By comparing the thirds, the condenser and MTA applicator groups showed higher density for apical and middle third than cervical third (p < 0.05). The ultrasound group presented similar density among the thirds. Conclusion: The filling ability was similar for the studied methods. Ultrasound promoted better distribution of MTA in retrograde cavity, but did not increase the density of material.

De novo transcriptome assembly for a non-model species, the blood-sucking bug Triatoma brasiliensis, a vector of Chagas disease

High throughput sequencing (HTS) provides new research opportunities for work on non-model organisms, such as differential expression studies between populations exposed to different environmental conditions. However, such transcriptomic studies first require the production of a reference assembly. The choice of sampling procedure, sequencing strategy and assembly workflow is crucial. To develop a reliable reference transcriptome for Triatoma brasiliensis, the major Chagas disease vector in Northeastern Brazil, different de novo assembly protocols were generated using various datasets and software. Both 454 and Illumina sequencing technologies were applied on RNA extracted from antennae and mouthparts from single or pooled individuals. The 454 library yielded 278 Mb. Fifteen Illumina libraries were constructed and yielded nearly 360 million RNA-seq single reads and 46 million RNA-seq paired-end reads for nearly 45 Gb. For the 454 reads, we used three assemblers, Newbler, CAP3 and/or MIRA and for the Illumina reads, the Trinity assembler. Ten assembly workflows were compared using these programs separately or in combination. To compare the assemblies obtained, quantitative and qualitative criteria were used, including contig length, N50, contig number and the percentage of chimeric contigs. Completeness of the assemblies was estimated using the CEGMA pipeline. The best assembly (57,657 contigs, completeness of 80 %, < 1 % chimeric contigs) was a hybrid assembly leading to recommend the use of (1) a single individual with large representation of biological tissues, (2) merging both long reads and short paired-end Illumina reads, (3) several assemblers in order to combine the specific advantages of each.

Simplified periodontal record for pregnant women

The assessment using the PSR (Periodontal Screening and Recording) of the prevalence and severity of and the basic treatment needs for periodontal disease in a group of pregnant women who attended the Preventive Dentistry Clinic at the School of Dentistry of Araraquara--UNESP. Forty-one pregnant women of 16 to 37 years of age, were examined. The PSR index was evaluated with a suitable periodontal probe (Trinity-model 621-WHO) with index codes scores of from 0 to 4, capable of indicating the presence of the following conditions: periodontal health, bleeding on probing, calculus, shallow and deep pockets. These codes were attributed to each sextant and could be marked with an asterisk (*) to indicate the presence of gingival recession, furcation lesions, mobility or any other mucogingival alterations. It is shown that 100% of the pregnant women had some kind of gingival alteration, represented mainly by PSR code 2 (56.1%) and * (19.5%). The women in the youngest age groups, 15-19 and 20-24 years, had code 2 as their highest score with no sextant excluded. In the 25-29 age group, the PSR code 2 still prevailed (54.5%) although codes 3 and 4 were already appearing. The code * and the occurrence of excluded sextants tended to increase in the oldest age group (30-37). In general, the affected sextants showed codes 1 and 2 more frequently, corresponding to 41.6% and 39.8% respectively, which represented a mean of 2.49 and 2.39 sextants affected in each pregnant woman. Regarding the treatment needs, 90.2% of the women needed some treatment beyond the preventive measures begun, including scaling and root planning and/or corrections of defective restorative margins (61%), and more complex treatment (29.2%). The meeting of the treatment needs during pregnancy must include special efforts to increase motivation and promote oral health, minimizing the possibility of vertical transmission of pathogenic microrganisms to the child, and thus contributing to the primary prevention of the main oral diseases.
