    Notes: Abstract: The nucleus 166Hf has been populated by the reaction 96Zr(74Ge,4n) using a beam energy of 310 MeV. -rays were detected with the EUROBALL III detector array. Fourteen new normal-deformed rotational bands, of which six form coupled pairs, have been observed in 166Hf. Four previously known bands have been extended to considerably higher spin, and configurations of the new bands are proposed. Two different bands have been assigned configurations involving the same orbitals at high spin. The two coupling schemes, deformation and rotation alignment, are discussed in connection with this new observation, which calls for a formulation of co-existing coupling schemes in six-quasiparticle structures involving the same orbitals at high spin.

    Notes: Abstract: A number of previously unobserved γ-rays emitted from the neutron-deficient nuclide 171Pt have been identified using the recoil decay tagging technique. The level scheme has been updated using information from γ-γ coincidences and angular distribution measurements. To further confirm the assignments of the γ-rays to 171Pt, the events were correlated with the alpha-decay of the daughter nucleus 167Os.

    Patterns of tissue remodeling after placement of ITI® dental implants using an osteotome technique: a longitudinal radiographic case cohort study (2004)

    Notes: Abstract: The aim of this prospective study was to document radiographically tissue remodeling patterns around ITI® implants placed according to an osteotome technique. In 19 consecutive patients from a private practice, 25 implants of the ITI® Dental Implant System were placed subjacent to the sinus floor. Implant beds were pre-prepared with pilot drills and/or using the Summers Osteotome Kit®. Bio Oss® particles were mixed with autologous bone and inserted into the apex area. Implants were placed self-tapping. The sinus floors were thereby pushed up with attempts not to sever the Schneiderian membrane. Healing occurred submerged or semi-submerged and was uneventful in 24/25 implants. At 1 year, all implants had been restored with crowns or short fixed partial dentures. One implant was lost in the first 3 weeks, but was replaced 6 months later in a second attempt. Intraoral radiographs were obtained presurgically and postsurgically at 3 and 12 months. The mean preoperative distance between the sinus floor and the crest was 7.0 mm (range 2.3–10.3 mm). The mean distances between the implant apex and the initial sinus floor were: 3.66±1.74 mm mesially and 4.44±1.62 mm distally. The mean height of the new bone reaching apically and mesially to the implants was 1.52±2.48 mm at surgery, but was reduced significantly to 1.24±1.30 mm at 3 months and 0.29±1.91 mm after 12 months (Hotelling's test P≤0.01). Similar values were obtained at the disto-apical aspects. In an attempt to assess periapical bone/graft remodeling, a novel index was applied: 0=no bone/graft visible, 1=cloudy appearance of new bone/graft, 2=clearly visible new bone/graft disappearing structures of original sinus floor, 3=new bone/graft with new cortical plate and the former boundary of the sinus floor disappearing. This index increased statistically significantly from baseline to 12 months (Hotelling's test P≤0.02). In conclusion, this study shows that in areas with reduced bone height subjacent to the sinus, an osteotome technique may provide a minimally invasive way to obtain implant abutments predictably. The grafted area apical to the implants undergoes shrinkage and remodeling. The original boundary of the sinus is eventually consolidated and replaced by a new cortical plate. In addition to the linear measurements, the novel index may assist in assessing periapical remodeling at implants placed with an osteotome technique.

    Simultaneous or staged installation with guided bone augmentation of transmucosal titanium implants (2003)

    Notes: Abstract: A prospective cohort study of 45 nonsmoking consecutively admitted patients was studied for the treatment outcomes following jaw bone augmentation in conjunction with installment of oral implants. Twenty-eight patients were treated for both bone augmentation and implant treatment simultaneously, while 17 patients were treated with a staged approach with the bone augmentation being performed 6–8 months prior to implant installation. Three months following this, prosthetic reconstructions were incorporated. One year thereafter, baseline data and 3 years after reconstruction, follow-up data were obtained. Moderately low mean scores for the bleeding on probing percentage were found at baseline (24%) and after 3 years of function (17%), while the corresponding values at the implant sites were 40.6% and 52.4%, respectively. However, the modified gingival index (mGI)=2 was found in only 4.8%, and 6.9% at the baseline and 3-year examinations. Peri-implant Probing depth (PPD) and level of attachment mean values did not vary between baseline and follow-up examinations. Only a small proportion of 1.8% yielded PPD=6.0 mm after 3 years of function. Radiographic bone level measurements showed that 18.2% of the implants lost 0.5 mm during the observation period. Seventy percent of the sites were considered completely stable. It was concluded that predictable treatment outcomes resulted for oral implant installation combined with or staged after jawbone augmentation. Only 6.5% of the sites had lost 1.5% crestal bone with the staged approach while 14% of the sites had lost 1.5 mm, when the implants were placed simultaneously. This suggests that the staged approach may have a lower risk for greater amounts of crestal bone loss as the simultaneous approach. In general, crestal bone loss encountered in the present study corresponded very well with that reported following placement of the same implant system into nonaugmented bone.

    Comparison of the clinical effects and gingival abrasion aspects of manual and electric toothbrushes (2001)

    Notes: Aims: The clinical effects and gingival abrasion aspects of 2 electrical toothbrushes (Braun Oral-B Plak Control Ultra and the novel development Braun Oral-B Plak Control 3D) were to be compared with conventional manual toothbrushing.Material and Methods: In a cross-over study, 26 dental student volunteers participated and were assigned to 1 of 3 groups. Following instruction in the use of the electric as well as manual toothbrushes, the volunteers were timed for 2 min each day to apply one electric or the manual toothbrush, respectively, during 3 experimental phases of 2 weeks. No other methods of tooth cleaning were to be performed except the one specified for the respective test period. When brushing manually, the Bass toothbrushing technique was applied. Between each test period, a recovery period of 1 week was allowed during which no oral hygiene was performed at all. At the start and the end of each of the experimental periods, the extension of plaque deposits from the gingival margin in coronal direction was assessed using the Turesky et al. modification of the Quigley and Hein plaque index. Presence or absence of gingival inflammation was evaluated by bleeding and probing (BOP). The extent and severity of gingival abrasions were assessed by use of a modified method of Breitenmoser et al. and adapted by Danser et al.〈section xml:id="abs1-2"〉〈title type="main"〉Results:The plaque-reducing effect was similar in all groups with the same cleaning regime. For that reason, the result of the different experimental phases with the respective cleaning modalities were collapsed. Cleaning with the Braun Oral-B Plak Control Ultra electric toothbrush resulted consistently in the lowest plaque scores when compared to both the Braun Oral-B Plak Control 3D and the manual toothbrush. Although the differences in plaque reduction were statistically significant between cleaning with Braun Oral-B Plak Control Ultra and 3D, they were small and of questionable clinical relevance. No significant differences in plaque reductions were found between manual brushing and any of the 2 electric brushes. Gingival abrasions were least pronounced following brushing with the Braun Oral-B Plak Control 3D electric toothbrush. However, no significant differences in gingival abrasion were encountered following brushing with the Braun Oral-B Plak Control Ultra electric in comparison with the manual toothbrush.Conclusions: The results of the present study have shown that in a group of dental students trained in manual brushing technique, where efficacy was similar with the 3 toothbrushes tested, there is no evidence of greater gingival abrasion with either Braun Oral-B Plak Control Ultra or 3D when compared with a manual brush.

    Notes: A 6-year-old girl with consanguineous parents presented with a history of progressive ataxia and patchy, segmental pigmentary changes, some reminiscent of Blaschko's lines. There was no evidence of oculocutaneous telangiectases or signs of immunodeficiency. A clinical diagnosis of ataxia–telangiectasia (AT) was suggested and confirmed by the presence of a low serum IgA, raised α-fetoprotein and chromosomal rearrangements of chromosomes 7 and 14. This case of AT is unique for having hypopigmentation and hyperpigmented patches adjacent to each other, which is a feature that has been described as ‘cutis tricolor’, and is unusual for having pigmentary skin changes, some in the lines of Blaschko without telangiectases. Clinicians should be aware that a diagnosis of AT may be made in the absence of telangiectases.

    Notes: Abstract The formation and evolution of galaxies is one of the great outstanding problems of astrophysics. Within the broad context of hierachical structure formation, we have only a crude picture of how galaxies like our own came into existence. A detailed physical picture where individual stellar populations can be associated with (tagged to) elements of the protocloud is far beyond our current understanding. Important clues have begun to emerge from both the Galaxy (near-field cosmology) and the high redshift universe (far-field cosmology). Here we focus on the fossil evidence provided by the Galaxy. Detailed studies of the Galaxy lie at the core of understanding the complex processes involved in baryon dissipation. This is a necessary first step toward achieving a successful theory of galaxy formation.
