AbstractObjectives: The aim of this study was to determine and compare the frequency of bacterial leakage of Streptococcus sanguinis biotype II along the implant–abutment interface between two systems of morse taper dental implants. Different methods of activation of the taper abutments were used: tapped‐in (Bicon©) and screwed‐in (Ankylos®).Materials and methods: Twenty sterile assemblies were used and attached, 10 Bicon© and 10 Ankylos® implants, according to manufacturers' specifications. They were then totally immersed within 20 test tubes containing a sterile nutrient solution brain–heart infusion (BHI). The internal part of the 20 implants was previously inoculated with 0.1 μl of S. sanguinis II (ATCC 10557) and then connected to the respective abutments. The assemblies were incubated under anaerobic conditions for 14 days in an autoclave at 37°C. They were monitored daily for solution cloudiness resultant from microbial leakage on the interface of the assemblies. For statistical analysis, the Fisher test was applied and significance was assigned at the 5% level.Results: There was solution cloudiness, indicating the finding of bacterial growth inside two Bicon© assemblies and two Ankylos® assemblies 48 h after incubation. Microbial leakage was further substantiated by testing the suspension for the presence of Streptococcus sp. None of the sterility controls were contaminated. The frequency of bacterial leakage along the implant–abutment interface, with the two different morse taper implant systems, was 20% of the assemblies of each system. There were no statistical differences between them.Conclusion: Irrespective of which of the two morse taper implant connection systems of activation was analyzed, tapped‐in (Bicon©) or screwed‐in (Ankylos®), this in vitro experiment showed bacterial leakage along the implant–abutment interface.

AbstractPurpose: The aim of this study was to evaluate crestal bone resorption and bone apposition resulting from immediate post‐extraction implants in the canine mandible, comparing a conditioned sandblasted acid‐etched implant surface with a non‐conditioned standard sandblasted implant surface.Material and methods: In this experimental study, third and fourth premolars and distal roots of first molars were extracted bilaterally from six Beagle dog mandibles. Each side of the mandible received three assigned dental implants, with the conditioned surface (CS) on the right side and the non‐conditioned surface (NCS) on the left. The dogs were sacrificed at 2 (n=2), 4 (n=2) and 12 weeks (n=2) after implant placement.Results: The microscopic healing patterns at 2, 4 and 12 weeks for both implant types (CS and NCS) yielded similar qualitative bone findings. The mean crestal bone resorption was found to be greater for all implants with NCS (2.28±1.9 mm) than CS (1.21±1.05 mm) at 12 weeks. The mean percentage of newly formed bone in contact with implants was greater in implants CS (44.67±0.19%) than with the NCS (36,6±0.11%). There was less bone resorption with the CS than the NCS.Conclusion: The data show significantly more bone apposition (8% more) and less crestal bone resorption (1.07 mm) with the CS than with the NCS after 12 weeks of healing. This CS can reduce the healing period and increase bone apposition in immediate implant placements. To cite this article:

AbstractObjectives: This study investigated the efficacy of new bone graft substitutes – biphasic calcium phosphates (BCP) made of submicron‐sized grains with fully interconnected wide‐range micron‐scale pores in two different macrodesigns: donut shaped with a 300–400 μm central macropore (n‐BCP‐1) or rod‐shaped (n‐BCP‐2) – in the healing of rabbit calvarial defects, and compared their bone‐healing properties with those of various commercial bone substitutes, which included substitutes with similar BCP composition (MBCP and Osteon), anorganic bovine bone (Bio‐Oss), and β‐TCP (Cerasorb).Material and methods: The surface morphology of the bone substitutes was investigated using scanning electron microscopy (SEM). Defects 8 mm in diameter were created in the calvaria of 30 adult male New Zealand White rabbits and were filled with six types of bone substitutes. The percentage of newly formed bone (NB%) was evaluated histomorphometrically 4 and 8 weeks after implantation.Results: SEM observation showed submicron‐sized grains with fully interconnected micropore structures in the n‐BCP‐1 and n‐BCP‐2 groups; these groups also showed considerable new bone formation in inner micropores as well as on the outer surfaces. The n‐BCP‐1 group exhibited enhanced new bone formation and direct ingrowth of bone tissue with blood vessels into central pores. Histomorphometric analysis showed significantly greater NB% in the n‐BCP‐1 group when compared with the other groups at 4 and 8 weeks (P<0.05).Conclusion: A new BCP ceramics made of submicron‐sized grains with a hierarchical pore structure was an effective osteoconductive material for the treatment of osseous defects of rabbit calvaria.

Daly B, Newton T, Batchelor P, Jones K. Oral health care needs and oral health‐related quality of life (OHIP‐14) in homeless people. Community Dent Oral Epidemiol 2010. © 2009 John Wiley & Sons A/SAbstract –  Objectives:  The aim of this study was (i) to determine the oral health status and oral health care needs of this population, (ii) to assess oral health‐related quality of life using OHIP‐14 and (iii) to explore whether there is a relationship between oral health status and oral health‐related quality of life.Methods:  A convenience sample was drawn from eight facilities catering for homeless people in south east London. Participants were invited to attend an outreach dental clinic and receive a clinical oral health and treatment needs assessment. The impact of oral disease was assessed using OHIP‐14.Results:  There were 102 people from a range of vulnerable housing situations invited to participate in the study. The mean age was 39.5 (SD ± 12.3) and 92% (n = 92) were men. The mean DMFT of dentate participants (n = 94) was 15.5 (SD ± 7.6), mean DT was 4.2 (SD ± 5.2), mean MT was 6.8 (SD ± 6.0) and mean FT was 4.6 (SD ± 4.8). Normative needs were extensive with 76% having a restorative need, 80% having a need for oral hygiene measures and periodontal treatment and 38% having a prosthetic treatment need. Ninety one per cent of homeless people experienced at least one impact and the mean number of impacts (n = 90) was 5.9 (SD ± 4.8).The most commonly experienced oral health‐related quality of life impacts were in the dimension of pain, with aching in the mouth having a prevalence of 65% and discomfort while eating foods having a prevalence of 62%. Forty‐four per cent felt handicapped by their oral condition. The experience of oral impact had only a slight relationship with clinical status and there were no differences in clinical status or oral impact by vulnerability of housing situation.Conclusions:  Oral health care needs were extensive and greater than that of the general population in the UK, although disease levels were similar. While homeless people experienced many more oral impacts (as measured with OHIP‐14) compared with adults of the same age in the general population in the UK, there was only a slight relationship with clinical status and oral health‐related quality of life.

Geyer S, Schneller T, Micheelis W. Social gradients and cumulative effects of income and education on dental health in the Fourth German Oral Health Study. Community Dent Oral Epidemiol 2010. © 2009 John Wiley & Sons A/SAbstract – Objective: To consider differential effects of income and education on oral health for each indicator separately and in combination. Finally the combined effects of the lowest income level and the lowest level of education were examined.Methods: Data were drawn from the Fourth German Oral Health Study. They were collected using proportional random sampling in order to obtain information also for less densely populated regions. The subjects included in the study were between 35 and 44 years of age (n = 925). It included a clinical dental examination and a sociological survey. Social differentiation was depicted by education and income (divided into categories), oral health was measured using the DMFT‐index.Results: Social gradients emerged for both indicators of social differentiation. The effects derived from single analyses were somewhat higher than those obtained by simultaneous estimations. The odds ratio of the lowest as compared with the highest income category was OR = 3.74 and OR = 2.34 in the analysis with both indicators. For education the respective effects were OR = 3.75 and OR = 2.95. The cumulative effect of the lowest income and the lowest educational level combined was OR = 6.06.Conclusion: Education and income are shaping social inequalities in oral health independently from each other, and they are only moderately correlated. They refer to different dimensions of disadvantage thus making preventive measures more complicated.

Community Dent Oral Epidemiol 2010. © 2010 John Wiley & Sons A/S.Abstract –  Objective:  To determine whether a Portuguese language version of the Child Perceptions Questionnaire for 11–14‐year‐olds (CPQ11‐14) showed differential item functioning (DIF) when compared with the original English language version.Methods:  CPQ11‐14 data from a school‐based Brazilian study (n = 138) was compared with CPQ11‐14 data collected as part of a school‐based study conducted in New Zealand (n = 322). In order to detect DIF, ordinal logistic regression analysis was performed with each CPQ11‐14 item as the dependent variable. The independent variables were language group (English versus Portuguese), the CPQ11‐14 sub‐scale score of which the item was a part, and an interaction term for language*sub‐scale score. Nonuniform DIF was deemed to be present if the interaction term was significant. Moderate to large uniform DIF was deemed to be present if after removing the interaction term the β coefficient (log odds ratio) for language group was significant and numerically greater than 0.64. Analyses were also undertaken to detect pseudo‐DIF.Results:  Nonuniform DIF was found in five items and moderate to large uniform DIF in an additional four items. Analyses using ‘purified’ sub‐scale scores indicated that little of the DIF detected was pseudo‐DIF. A comparison of the language groups using DIF affected and DIF‐free overall and subscale CPQ11‐14 scores revealed that the DIF detected had only a marginal effect on the differences between language groups in scores.Conclusion:  Oral health‐related quality of life questionnaires, particularly those that have been translated, need to be assessed for DIF and its likely impact on group comparisons.
Original Research—Ejaculatory Disorders: The Role of Short Frenulum and the Effects of Frenulectomy on Premature Ejaculation
Authors: Gallo Luigi , Perdonà Sisto , Gallo Antonio 
Published: January 2010

ABSTRACTIntroductionThe role of short frenulum and the effects of frenulectomy on premature ejaculation (PE) were never investigated.AimsThe aims of this study were to evaluate the prevalence of short frenulum in a population of patients affected by lifelong PE and to investigate the role of frenulectomy as first-line treatment for this condition.MethodsWe performed frenulectomy to patients complaining of lifelong PE in which we found the presence of a short frenulum at physical examination. We evaluated intravaginal ejaculatory latency time (IELT) and the score of a validated PE questionnaire at baseline and after frenulectomy.Main Outcome MeasuresWe evaluated the change in mean IELT and in mean PE questionnaire score.ResultsWe found the presence of a short frenulum in 59 out of 137 (43%) subjects who came to our center complaining of lifelong PE. Mean age of study population was 38.2 years (±5.3 standard deviation). At baseline period, mean IELT was 1.65 minutes (±1.15), and mean PE questionnaire score was 15.8 (±2.85). No complications related to surgery occurred. Mean follow-up time was 7.3 months (±3.18). After frenulectomy, mean IELT was 4.11 minutes (±1.77), and mean PE questionnaire score was 9.85 (±3.2). An increase in mean IELT of 2.46 minutes (P &lt;0.0001) and a reduction in mean PE questionnaire symptoms score of 5.95 (P &lt;0.0001) were noted.ConclusionShort frenulum is a genital anomaly found in 43% of individuals affected by lifelong PE in our data set. We suggest always ruling out at physical examination the presence of a short frenulum in all patients complaining of PE and to propose frenulectomy as first-line treatment in these cases.

Published: January 2010

ABSTRACT

Introduction
Menopause requires psychological and physical adjustments because of the occurring significant hormonal changes. Sexuality is one of the aspects that undergoes the most profound modifications. Preliminary data suggest that sometimes women do not regard sexual changes as problematic and often readjust their life and relationship according to their new physical status.

Aim
The aim of our study was to evaluate sexual function and the way women feel by comparing healthy postmenopausal and premenopausal women.

Methods
One hundred menopausal (M) and 100 premenopausal (pM) healthy women were asked to complete anonymous questionnaires to assess sexual function and stress related to sexual activity.

Main Outcome Measures
Female Sexual Function Index (FSFI), Female Sexual Distress Scale (FSDS) were completed by M and pM women.

Results
Medium FSFI score was 20.5 ± 9.6 and 26.4 ± 7.7 (P &lt;0.0005) and medium FSDS score was 12.1 ± 11.7 (95% CI 9.7–14.4) and 11.3 ± 10.2 (P = 0.917) for M and pM women, respectively. Twenty-five of the 69 M women and 20 of the 31 pM women with a pathological score in the FSFI questionnaire scored higher than 15 in the FSDS (P &lt;0.0005). The overall prevalence of sexual dysfunction was 20% and 25% (P = 0.5) in the M and pM women.

Conclusions
Our data confirm that menopause is associated with changes in sexual function that may be compatible with sexual dysfunction. However, personal distress caused by these changes in sexual life appears to be lower among menopausal women (36.2%) as compared with premenopausal women (64.5%). These data suggest that medical treatment for sexual health in menopause must be highly personalized and carefully prescribed.
The Phallus Tree: A Medieval and Renaissance Phenomenon
Authors: Mattelaer Johan J. 
Published: January 2010

ABSTRACT

Introduction
In the year 2000, an exceptional mural was discovered at a fountain in Massa Marittima, Italy. It depicts a tree with phalluses, which are distributed across all the branches, are disproportionately large and in an aroused state, and include a scrotum.

Methods
Other examples were identified by systematic literature research.

Results
Several other depictions of a phallus tree from the medieval and Renaissance periods exist, for example in manuscripts, as wood carvings, on pilgrimage badges, or frescoes, and were retrieved in Germany, Italy, Belgium, the Netherlands, Turkey, and France.

Discussion and Conclusions
The phallus tree was a well-known phenomenon in Western Europe during the late Middle Ages and the beginning of the Renaissance, and mostly find their roots in the link between infertility and impotence on the one hand, and sorcery and witchcraft on the other.
Rheological Behavior of High‐Concentration Sodium Caseinate Dispersions
Authors: Loveday Simon M. , Rao M. Anandha , Creamer Lawrence K. , Singh Harjinder 
Published: January 2010

ABSTRACT:  Apparent viscosity and frequency sweep (G′, G″) data for sodium caseinate dispersions with concentrations of approximately 18% to 40% w/w were obtained at 20 °C; colloidal glass behavior was exhibited by dispersions with concentration ≥23% w/w. The high concentrations were obtained by mixing frozen powdered buffer with sodium caseinate in boiling liquid nitrogen, and allowing the mixtures to thaw and hydrate at 4 °C. The low‐temperature G′−G″ crossover seen in temperature scans between 60 and 5 °C was thought to indicate gelation. Temperature scans from 5 to 90 °C revealed gradual decrease in G′ followed by plateau values. In contrast, G″ decreased gradually and did not reach plateau values. Increase in hydrophobicity of the sodium caseinate or a decrease in the effective volume fraction of its aggregates may have contributed to these phenomena. The gelation and end of softening temperatures of the dispersions increased with the concentration of sodium caseinate. From an Eldridge–Ferry plot, the enthalpy of softening was estimated to be 29.6 kJ mol−1.Practical Application: The results of this study should be useful for creating new products with high concentrations of sodium caseinate.
Innovation and Conflict Management in Work Teams: The Effects of Team Identification and Task and Relationship Conflict
Authors: Desivilya Helena Syna , Somech Anit , Lidgoster Helena 
Published: January 2010

AbstractThe current study attempted to elucidate the mechanisms whereby constructive‐cooperative conflict management (integrating) fosters innovation in work teams. The proposed conceptual model postulated that the positive function of integrating in precipitating innovation is motivated by prosocial team atmosphere as manifested in team identity, the team’s capacity to mitigate the adverse impact of relationship conflict and its capability to maximize the potential gains of task conflict. Specifically, it was hypothesized: (a) integrating would predict innovation. (b) Team identity would be positively related to integrating, and that integrating would mediate the positive relationship between team identity and team innovation. (c) Task conflict would be positively related to integrating whereas relationship conflict would be negatively related to integrating. This research embraced a team‐level perspective and analysis. Seventy‐seven intact work teams from high‐technology companies participated in the study. The findings, by and large, supported the proposed conceptual model, especially the contention that teams’ proclivities with respect to conflict management play a pivotal role in their capacity to function in an innovative manner. A team’s integrating pattern meaningfully predicted team innovation. The mediating effect of the integrating strategy on the relationship between team identity and team innovation was also demonstrated. Finally, relationship conflict was negatively associated with a team’s integrating pattern, while the positive association of task conflict with the cooperative strategy was marginally significant.
Electronic Signatures and Interpersonal Trustworthiness in Online Negotiations
Authors: Kurtzberg Terri R. , Naquin Charles E. 
Published: January 2010

AbstractCorporate‐mandated signature lines in professional e‐mail messages (i.e., those required and often added automatically by the company’s server) are an increasingly common practice in organizations. This research empirically explores the impact of one such electronic signature upon judgments of interpersonal trustworthiness in online negotiations. Specifically, we compare the impact of what we call the “disclaimer” signature (statements that the e‐mail represents the opinion of the sender and not necessarily the organization) to “non‐disclaimer” signatures (statements of confidentiality.) Findings indicate that negotiators who received such a disclaimer signature tended to judge the sender as less trustworthy and also receive lower objective outcomes than did those who either did not have any statement, or those who had one with different (non‐disclaimer) content.
Prospective contralateral eye study to compare conventional and wavefront‐guided laser in situ keratomileusis
Authors: D’Arcy Fiona , Kirwan Caitriona , Qasem Qasim , O’Keefe Michael 
Published: January 2010

Abstract.Purpose:  To compare outcomes of customized/wavefront guided with conventional ablation in myopic patients with or without astigmatism undergoing laser in situ keratomileusis.Methods:  A prospective, comparative, contralateral eye study was performed. Sixty‐eight eyes of 34 myopic patients with similar refractive error in both eyes were included. One eye was randomly selected to undergo conventional and the fellow eye customized ablation. Surgery was performed using the Technolas 217z laser (Bausch & Lomb, Surrey, UK). Uncorrected visual acuity, manifest refractive spherical equivalent (MRSE), astigmatism, aberrometry and contrast sensitivity were recorded pre and 3 months postoperatively.Results:  Mean MRSE treated in the conventional and customized groups were 3.77 ± 1.61 dioptres and −3.83 ± 1.59 dioptres respectively. Three months postoperatively there was no significant difference between the groups in mean MRSE (p = 0.99) or cylinder (p = 0.56). The factor increase in postoperative total higher order aberrations (HOAs) was less in the customized (1.32) compared with the conventional (1.54) treatment group but did not reach statistical significance (p = 0.08). Scotopic contrast sensitivity decreased significantly postoperatively in the conventional but not in the customized treatment group.Conclusion:  Visual acuity and refractive error outcomes were similar in both treatment group and no patient preference was observed. Customized ablation was associated with a smaller but not statistically significant postoperative increase in HOAs, better preservation of scotopic contrast sensitivity, quicker treatment time and removal of less corneal tissue.
