Prosthetic rehabilitation of a patient with gastroesophageal reflux disease: 4-year followup

The gastroesophageal reflux disease (GERD) is one of the main causes of dental erosion. The aim of this case presented is to describe the prosthetic rehabilitation of a patient with GERD after 4 years of followup. A 33-year-old male patient complained about tooth sensitivity. The lingual surface of the maxillary anterior teeth and the cusps of the upper and lower posterior teeth presented wear. It was suspected that the feeling of heartburn reported by the patient associated with the intake of sports supplements (isotonics) was causing gastroesophageal changes. The patient was referred to a gastroenterologist and was diagnosed with GERD. Dental treatment was performed with metal-free crowns and porcelain veneers after medical treatment of the disease. With the change in eating habits, the treatment of GERD and lithium disilicate ceramics provided excellent cosmetic results after 4 years and the patient reported satisfaction with the treatment.

A influência da orientação motivacional durante o treinamento de atletas iniciantes no tênis de campo

The motivation in the sport has been one of the most studied subjects nowadays, as much that some authors say that the motivation is the base for the success of an athlete, that is, the psychological part must also well be stimulated so that if it reaches the maximum level of concentration during a game it will obtains the expected result. Tennis is one of the sports that more grew in recent years, and together with this fast ascension also increased the number of interested in researching in this area of the Psychology of the Sport. The present study has as objective to begin the adaptation and validation of the interest scale and to analyze the influence of the motivational orientation of the athletes in the sportive performance of the Tennis through the application of scale Teosq – Task and Ego Orientation in Sport Questionnaire (DUDA, 1992), translated, adapted and validated by Hirota and De Marco (2006), where we can identify if the individual is guided for a task or an ego’s goal. This research was carried through in a situated academy of Tennis in the City of Cotia – SP – Brazil, counting on the participation of 20 citizens with age between 09 and 18 years of both the practicing sexes of Tennis. The calculation of the Alpha Coefficient of Cronbach was adopted as statistical method, in order to identify the trust worthy and validity of the instrument beyond the average of each orientation, to be able to verify the athlete’s motivational orientation. For the analysis of the results, the Alpha Coefficient was observed high, compared with previous studies, reaching values of orientation for the ego of 0,90, and 0,70 of orientation for task. They had been registered the following averages, 4,20 (+0,93) and 2,42 (+0,85), respectively of orientation for task and ego. With those results we can point that, the scale applied with the proposal to identify the motivational orientation of the athletes of Tennis, revealed efficiency, and trust worthy in its application, and in accordance with the results, the athletes are guided for task, revealing self-determination, selfconfident, more creative and they judge its success for the quality of the carried through work.

Evaluation of the best-designed graded exercise test to assess peak treadmill speed

This study examined the influence of different speed increments during treadmill exercise tests on peak treadmill speed (Vpeak) and its relationship with a 1-h treadmill running performance. 18 male recreational and amateur runners (10-km running pace: 10–15 km·h−1) performed, in an alternate order, 3 continuous incremental exercise tests with different speed increments (0.5, 1.0 and 2.0 km·h−1) on a motorized treadmill to determine Vpeak. Thereafter they undertook a 1-h time trial on a treadmill. Vpeak was determined as either (a) the highest speed that could be maintained for a complete minute (Vpeak-60 s), (b) the speed of the last complete stage (Vpeak-C), or (c) the speed of the last complete stage added to the product of the speed increment and the completed fraction of the incomplete stage (Vpeak-P). The Vpeak values were highly influenced by the different speed-incremented rates and the Vpeak-P determined during the protocol comprising speed increments of 1 km·h−1 presented the highest correlation with 1-h time trial performance (r=0.89). The results suggest that a protocol with speed increments comprising 1 km·h−1 and with a 3-min stage duration should be used as standard for the determination of Vpeak to assess aerobic fitness and predict endurance performance in recreational runners. Furthermore, the Vpeak-P should be used for the determination of Vpeak.
