Abstract: The extraction of teeth involves the elimination of extremely sensitive periodontal mechanoreceptors, which play an important role in oral sensory perception. Objectives: The aim of this study was to evaluate the recovery of interocclusal sensory perception for micro-thickness in individuals with different types of implant-supported prostheses. Materials and Methods: Wearers of complete dentures (CDs) comprised the negative control group (group A, n=17). The experimental group consisted of wearers of prostheses supported by osseointegrated implants (Group B, n=29), which was subsequently divided into 4 subgroups: B1 (n=5) – implant supported overdentures (ISO) occluding with CD; B2 (n=6) – implant-supported fixed prostheses (ISFP) occluding with CD; B3 (n=8) – wearers of maxillary and mandibular ISFP, and B4 (n=10) – ISFP occluding with natural dentition (ND). Individuals with ND represented the positive control group (Group C, n=24). Aluminum foils measuring 10 μm, 24 μm, 30 μm, 50 μm, 80 μm, and 104 μm thickness were placed within the premolar area, adding up to 120 tests for each individual. Results: The mean tactile thresholds of groups A, B1, B2, B3, B4, and C were 92 μm, 27 μm, 27 μm, 14 μm, 10 μm, and 10 μm, respectively. [Correction added after publication online 18 April 2008: in the preceding sentence 92 μm, 27 μm, 14 μm, 10 μm and 10 μm, was corrected to 92 μm, 27 μm, 27 μm, 14 μm, 10 μm and 10 μm.] The Kruskal-Wallis test revealed significant difference among groups (P<0.05). The Dunn test revealed that group A was statistically different from groups C, B3, and B4, and that B1 and B2 were statistically different from group C. Conclusion: Progressive recovery of osseoperception as a function of the combination of implant-supported prostheses could be observed. Moreover, ISO and/or ISFP combinations may similarly maximize the recovery of osseoperception.

Abstract: OBJECTIVES To compare the patient-reported effect of treatment with implant-supported fixed prosthesis (ISFP) and fixed dental prosthesis (FDP) in patients with a small number of tooth losses to replace. METHODS From a population of 155 patients receiving either ISFP or FDP, 68 patients were matched in pairs based on gender, number of teeth replaced, zone of replacement, age and number of remaining teeth. The patient-reported effect was prospectively obtained by measuring change in the short-form oral health impact (OHIP-14) from before to one month after treatment. Effect size (ES), standardised response mean (SRM) and a minimal important difference of two units were applied to estimate the magnitude of the change. RESULTS Both the ISFP and FDP groups decreased significantly in OHIP-14 after treatment (P < .01). The change was not significantly different between the ISFP and FDP groups. The magnitude of the change was for both treatments moderate and slightly higher in the ISFP group (ES = 0.52 and SRM = 0.58) than in the FDP group (ES = 0.48 and SRM = 0.47). Applying the minimal important difference showed that 23 participants in the ISFP group and 21 in the FDP group had good effect. CONCLUSIONS The patient-reported effect of treatment with ISFP or FDP was similar, clinically meaningful and of moderate magnitude in patients with a small number tooth losses to replace.

Abstract: College student-athletes face many unique role strains during their academic and athletic career, which may impact the way in which they understand themselves. This study was designed to explore whether college student-athletes have a different perceived personality preference than their non-athlete counterpart. Ninety-one college students took the Myers-Brigg Type Indicator. The researchers found no statistical differences between the athletes and the non-athletes, however, several of the results seemed noteworthy and are presented. ********** Student-athletes are a unique population among college campuses across the nation. In 2004, the NCAA (National Collegiate Athletic Association) encompassed 361,175 athletes at 1,263 universities (NCAA, 2005). Weiss (1999) found that athletes tend to have a higher likelihood of showing maladaptive behavior than nonathletes. Ferrante, Etzel, & Lantz (1996) point out that psychological development, health, and daily functioning create complex internal and external stressors that seem to make athletes more vulnerable than most college students to encounter greater frequencies and higher levels of personal-social distress. Based on the notion that being involved with competitive sports, usually for many years, may have an impact on a person's personality, or perceived sense of personality, the purpose of this study was to determine whether there were differences in perceived personality preferences between college student-athletes and college non-athletes. Procedure Participants were recruited through a convenience sampling technique from various areas of a large private southeastern university. After reading and signing the informed consent form, participants were given the Myers-Briggs Type Inventory (MBTI) Form G. The MBTI consists of 93 forced pair choices where the participant selects the answer that is closest to describing how s/he usually feels or acts or appeals to more. The test was designed off of Carl Jung's theory of psychological types and contains four separate indices (Myers & McCauley, 1985). The indices are El (Extraversion or Introversion), SN (Sensing or Intuitive), TF (Thinking or Feeling), and JP (Judgment or Perception). There are sixteen possible characteristic types which include one or the other of the four preference choices (i.e. ISFP or ENTJ). Each type has distinct personality characteristics. Participants took approximately 10 minutes to fill out the form. All forms were then scored by one of the researchers and the four lettered type was recorded, including the score on each of the eight dimensions. Data and Analysis The data consisted of ninety-one undergraduate students from a large NCAA Division II southeastern university who volunteered to take the Myers-Briggs Type Indicator (MBTI). There are approximately 3,300 undergraduate students on the main campus. The athletics department (NCAA Division II status) houses 174 athletes (70 male athletes and 104 female athletes). Participants consisted of 32% males and 68% females. Their ages ranged from 18-24 with a mean age of 20.07 and a standard deviation of 1.47. Of the participants, 47% were student-athletes and 53% were non student-athletes. Participants' stated ethnicities were compiled into four categories: 53% Caucasians, 21% Hispanics, 14% African-Americans, and 12% "other". Data analysis consisted of scoring the MBTI for each participant and comparing scores on each of the eight personality characteristic scales (E, I, S, N, T, F, J, P). t-tests were used to determine difference on each of the indices between the college student-athletes and the nonathletes. Findings and Discussion The data did not show significant differences in any of the indices of the MBTI (p
