Article Synopsis
- A study examined the effects of a standardization and calibration training program on the reproducibility of manual periodontal probing performed by a new periodontist.
- The training included 24 hours of instruction and required high levels of measurement agreement for the periodontist to successfully complete it.
- Results showed that the trained periodontist achieved excellent measurement consistency, though errors were greater in areas with more gum inflammation, indicating the program's effectiveness in improving probing accuracy.
Common and Unique Barriers to the Exchange of Administrative Healthcare Data in Environmental Public Health Tracking Program.
Int J Environ Res Public Health
April 2021
CDC's National Environmental Public Health Tracking Program (Tracking Program) receives administrative data annually from 25-30 states to track potential environmental exposures and to make data available for public access. In 2019, the CDC Tracking Program conducted a cross-sectional survey among principal investigators or program managers of the 26 funded programs to improve access to timely, accurate, and local data. All 26 funding recipients reported having access to hospital inpatient data, and most states (69.

Background: Susceptibility to periodontitis has been associated with several risk factors, including allelic variants at multiple gene loci. Variations in the IL-1 gene cluster have been linked with increased risk for periodontitis.
Feasibility of Capturing Cancer Treatment Data in the Utah All-Payer Claims Database.
JCO Clin Cancer Inform
October 2019
Purpose: Incompleteness of treatment data is a recognized limitation of cancer registry data. An all-payer claims database (APCD) is a tool that states use to capture health care information across systems and payer. We linked the Utah Cancer Registry (UCR) records to Utah's statewide APCD and evaluated how this linkage led to improvements in the capture of cancer treatment information.
View Article and Find Full Text PDFObjective: To evaluate the linkage of claims from the Utah All Payers Claims Database (APCD) and Utah Cancer Registry (UCR).
Data Sources: Secondary data from 2013 and 2014 Utah APCD and 2013 UCR cases.
Study Design: This is a descriptive analysis of the quality of linkage between APCD claims data and cancer registry cases.
Background: Patients who consult a physical therapist for low back pain (LBP) may receive initial and subsequent management from different therapists. The impact that physical therapy provider continuity has on health care use in patients with LBP is insufficiently studied.
Objective: The objective of this study was to examine the impact of continuity of the physical therapy provider on health care use and costs in patients with LBP referred from primary care.
Background: The root coverage esthetic score (RES) was published in 2009 as an esthetic scoring system to measure visible final outcomes of root coverage procedures performed on Miller I and II recession defects. The aim of this study was to evaluate the intra-examiner, intra-group, and inter-examiner reliability of the RES when used among periodontal faculty, post-graduate students in periodontology, and pre-doctoral DMD students when using the RES at Tufts University School of Dental Medicine (TUSDM).
Methods: Thirty-three participants (12 second-year DMD students, 11 periodontal residents, and 10 faculty members) were assembled to evaluate 25 baseline and 6-month post-treatment outcomes of mucogingival surgeries using the RES.
Guided Tissue Regeneration Involving Piercing-Induced Lingual Recession: A Case Report.
Int J Periodontics Restorative Dent
November 2017
Recession on the lingual aspect of mandibular incisors may occur in patients with history of tongue piercing and other factitious traumatic habits. Treatment of these areas is challenging due to the site-specific anatomical features of the region. This case report presents a novel approach for a specific type of mandibular lingual defect caused by tongue piercing.

- The study examines how different barrier membranes (collagen matrix vs. extracellular matrix) impact the preservation of soft and hard tissues after tooth extraction and alveolar ridge preservation (ARP) procedures.
- Researchers measured tissue dimensions before and 4 months after ARP in 23 patients, finding both membranes resulted in increased gingival thickness but some ridge width reduction.
- While the differences between the two membrane types weren't statistically significant, preoperative bone thickness affected the changes in tissue dimensions after the procedure.
This study assessed the subgingival occurrence of the flagellated, Gram-negative, anaerobic rod Centipeda periodontii in chronic periodontitis and periodontal health/gingivitis with species-specific nucleic acid probes, and evaluated the in vitro resistance of subgingival isolates to therapeutic levels of amoxicillin, metronidazole, and doxycycline. Subgingival plaque biofilm specimens from 307 adults with chronic periodontitis, and 48 adults with periodontal health/localized gingivitis, were evaluated with digoxigenin-labeled, whole-chromosomal, DNA probes to C. periodontii ATCC 35019 possessing a 10(4) cell detection threshold.

These mucogingival alterations may become a challenge to manage in the maxillary anterior region among patients with a high lip line upon smiling or high esthetic demands. To further complicate matters, the presence of physiologic gingival pigmentation in the esthetic zone creates challenges of its own.

Methods: An experimental hydroxyapatite (HA) grit-blasted and dual acid-etched titanium surface (BAE-1) was compared to an experimental HA grit-blasted and dual acid-etched surface treated with nanometer-scale crystals of HA (BAE-2). Both experimental implant surfaces were implanted onto the tibias of 4 New Zealand white rabbits.
Article Synopsis
- - This study analyzed the resistance of hard red winter wheat variety Halt to the Russian wheat aphid, comparing it to the susceptible variety TAM 107 across four growth stages.
- - Halt demonstrated antixenosis at growth stage Zadoks 30 and antibiosis affecting various reproductive factors of the aphid, with fewer nymphs and lower reproductive rates compared to TAM 107.
- - Damage assessments showed Halt was less affected by chlorosis and leaf rolling from aphid infestation than TAM 107, suggesting Halt may be suitable for integrated pest management, although care should be taken to avoid selecting for more resistant aphid biotypes.
Article Synopsis
- Dental implants for single-tooth replacements face challenges due to lack of support from surrounding teeth and increased masticatory forces, leading to a higher risk of failure compared to bridged implants.
- A clinical trial involving 59 patients assessed 71 implants for complications like mobility, infection, and crestal bone loss over an average of 45.9 months, with a notable success rate.
- The results showed a 98.6% success rate for dual acid-etched implants, indicating they perform well, even in poor quality bone and for immediate replacements, comparable to bridged implants.
