Periodontal Referral Patterns of General Dentists: Lessons for Dental Education

The objectives of this study were to investigate periodontal treatment and referral patterns and the considerations used in the process of dentists who make no periodontal referrals, relatively few referrals, or more referrals. Specifically, the role of disease characteristics, patient‐ and provider‐related factors, attitudes towards periodontal referrals, and perceptions of dental education were explored. The relationships between the perceived quality of dental education concerning periodontal diagnosis and treatment and the considerations used in this process were evaluated as well. Data were collected from 160 members of the Michigan Dental Association using a mailed questionnaire. The respondents were predominantly male (77 percent) and white (96 percent) and had practiced for an average of twenty‐three years (SD=10.7). While 13 percent of the respondents had not made any periodontal referrals during the past month, 69 percent had referred between one and five patients, and 18 percent more than five patients. Dentists who referred more than three patients per month considered the patients’ oral hygiene as more important, had fewer patients from lower socioeconomic backgrounds and more patients with private insurance, and felt less well prepared by their dental education compared to general dentists who referred fewer than three patients per month to a periodontist. The more positively dentists evaluated their dental education in periodontics, the more conservative they were when considering percentage of bone loss as a basis for referral (r=.228; p=.014), the more frequently they used systemic antibiotics in their treatment of periodontal disease (r=.180; p=.036), and the more they considered whether their patients would return after the periodontal treatment (r=.185; p=.028) as a factor in their referral decisions. General dentists’ perceptions of the quality of their dental school education in periodontics decreased their willingness to refer patients and increased their desire to treat these patients in their own practices. Future research should analyze the ways in which dental school curricula could prepare students to make timely and necessary periodontal referrals.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/153664/1/jddj002203372009732tb04655x.pd

Dust Reddening in SDSS Quasars

We explore the form of extragalactic reddening toward quasars using a sample of 9566 quasars with redshifts 0<z<2.2, and accurate optical colors from the Sloan Digital Sky Survey (SDSS). We confirm that dust reddening is the primary explanation for the red ``tail'' of the color distribution of SDSS quasars. Our fitting to 5-band photometry normalized by the modal quasar color as a function of redshift shows that this ``tail'' is well described by SMC-like reddening but not by LMC-like, Galactic, or Gaskell et al. (2004) reddening. Extension to longer wavelengths using a subset of 1886 SDSS-2MASS matches confirms these results at high significance. We carry out Monte-Carlo simulations that match the observed distribution of quasar spectral energy distributions using a Lorentzian dust reddening distribution; 2% of quasars selected by the main SDSS targeting algorithm (i.e., which are not extincted out of the sample) have E_{B-V} > 0.1; less than 1% have E_{B-V} > 0.2, where the extinction is relative to quasars with modal colors. Reddening is uncorrelated with the presence of intervening narrow-line absorption systems, but reddened quasars are much more likely to show narrow absorption at the redshift of the quasar than are unreddened quasars. Thus the reddening towards quasars is dominated by SMC-like dust at the quasar redshift.Comment: 29 pages including 8 figures. AJ, September 2004 issu

Correlative In Situ Multichannel Imaging for Large-Area Monitoring of Morphology Formation in Solution-Processed Perovskite Layers

To scale up production of perovskite photovoltaics, state-of-the-art laboratory recipes and processes must be transferred to large-area coating and drying systems. The development of in situ monitoring methods that provide real-time feedback for process control is pivotal to overcome this challenge. Herein, correlative in situ multichannel imaging (IMI) obtaining reflectance, photoluminescence intensity, and central photoluminescence emission wavelength images on areas larger than 100 cm2 with subsecond temporal resolution using a simple, cost-effective setup is demonstrated. Installed on top of a drying channel with controllable laminar air flow and substrate temperature, IMI is shown to consistently monitor solution film drying, perovskite nucleation, and perovskite crystallization. If the processing parameters differ, IMI reveals characteristic changes in large-area perovskite formation dynamics already before the final annealing step. Moreover, when IMI is used to study >130 blade-coated devices processed at the same parameters, about 90% of low-performing devices contain coating inhomogeneities detected by IMI. The results demonstrate that IMI should be of value for real-time 2D monitoring and feedback control in industrial-scale, high-throughput fabrication such as roll-to-roll printing

Accuracy and Consistency of Radiographic Interpretation Among Clinical Instructors in Conjunction with a Training Program

There are inaccuracies and inconsistencies of radiographic interpretation among clinical instructors. The purpose of this investigation was to determine if a training program could improve the accuracy and consistency of instructors’ ratings of bone loss. A total of thirty-five clinical instructors consisting of periodontal faculty (periodontists and general dentists), dental hygiene faculty, and periodontal graduate students viewed projected digitized radiographic images and quantified bone loss for twenty-five teeth into four descriptive categories. Ratings of bone loss were made immediately before (pretest) and after (post-test 1) initiation of the training program and then again three months later (post-test 2). Ratings were compared to the correct choice categories as determined by direct measurement using the Schei ruler. Overall agreement with the correct choice improved over time (from 64.5 percent to 85.2 percent) with the greatest change from pretest (64.5 percent) to post-test 1 (76.5 percent). Mean and absolute differences improved in three of the four categories, but worsened in one from pretest to post-test 1. This category returned to its original high value at post-test 2. The greatest improvement in consistency among instructors’ ratings was seen in one of the four categories, which was “none” (no bone loss). Extension of the training program may further enhance the accuracy and consistency of instructors’ radiographic interpretation
