Genetic power of a Brazilian three-generation family with generalized aggressive periodontitis. II

The genetic power of a Brazilian three-generation family with generalized aggressive periodontitis (GAgP) has been reported. The empirical logarithms of the odds (LOD) score thresholds for genetic linkage analysis of complex diseases proposed by Haines rely on confirmation from independent datasets. This study estimated the power of another large Brazilian family with GAgP for future linkage analysis. The three-generation family was seen at the Dental School of the Federal University of Bahia. Following the previously described methodology, full-mouth periodontal probing at 6 sites/tooth was performed in all 19 family members. Six out of 12 siblings were affected with GAgP. All affected family members were non-smokers and did not present diabetes or any other systemic condition or consanguinity. A parametric simulation (θ=0) was performed on 100 replicates using the statistical software SLINK for linkage analysis. There was maximum expected LOD scores of 3.75 and 3.45 at penetrance rate F=0.98, and both studied phenocopy rates P=0.0 and P=0.02, respectively. The power of the study increased with the increase of the adopted penetrance rates in both studied phenocopy rates. The studied Brazilian three-generation family showed statistical power for future genetic linkage analysis of candidate genes to GAgP.     

Roughness of human enamel surface submitted to different prophylaxis methods

The purpose of this in vitro study was to evaluate alterations in the surface roughness and micromorphology of human enamel submitted to three prophylaxis methods. Sixty-nine caries-free molars with exposed labial surfaces were divided into three groups. Group I was treated with a rotary instrument set at a low speed, rubber cup and a mixture of water and pumice; group II with a rotary instrument set at a low speed, rubber cup and prophylaxis paste Herjos-F (Vigodent S/A Indústria e Comércio, Rio de Janeiro, Brazil); and group III with sodium bicarbonate spray Profi II Ceramic (Dabi Atlante Indústrias Médico Odontológicas Ltda, Ribeir?o Preto, Brazil). All procedures were performed by the same operator for 10 s, and samples were rinsed and stored in distilled water Pre and post-treatment surface evaluation was completed using a surface profilometer (Perthometer S8P, Marh, Perthen, Germany) in 54 samples. In addition, the other samples were coated with gold and examined in a scanning electron microscope (SEM). The results of this study were statistically analyzed with the paired t-test (Student), the Kruskal-Wallis test and the Dunn (5%) test. The sodium bicarbonate spray led to significantly rougher surfaces than the pumice paste. The use of prophylaxis paste showed no statistically significant difference when compared with the other methods. Based on SEM analysis, the sodium bicarbonate spray presented an irregular surface with granular material and erosions. Based on this study, it can be concluded that there was an increased enamel surface roughness when teeth were treated with sodium bicarbonate spray when compared with teeth treated with pumice paste.     

Scapular dyskinesis in trapezius myalgia and intraexaminer reproducibility of clinical tests

The aims were to test the intraexaminer reproducibility and report the presence of specific clinical variables of scapular dyskinesis in cases with trapezius myalgia and healthy controls, along with general health and work ability. A total of 38 cases and 23 controls were tested for scapular dyskinesis, general health, and work ability, and 19 cases and 14 controls participated in the reproducibility study. Intraexaminer reproducibility was good to excellent for 6 of 10 clinical variables (Intraclass Correlation Coefficient [ICC] 0.76-0.91; kappa 0.84-1.00), and fair to good for four variables (ICC 0.42-0.74), test for muscular weakness having the lowest ICC (0.42). Cases showed significantly larger medial border misalignment, larger lower horizontal distance of the inferior scapular angle and larger passive shoulder internal rotation, by 110% (1.02?cm), 15% (1.38?cm), and 8% (5.5°), respectively. Cases with the highest degree of scapular dyskinesis showed reduced work ability and general health. The present specific clinical variables on scapular dyskinesis showed satisfactory intraexaminer reproducibility. An increased standardization must be implemented to increase reproducibility of tests for muscular weakness, and the interexaminer reproducibility must be tested for all variables. Finally, scapular dyskinesis in cases with trapezius myalgia must be followed longitudinally for clinical importance.
