- OBJECTIVE: A previous sham-controlled multinational study demonstrated the short-term efficacy and safety for xerostomia treatment of an intraoral device that delivers electrostimulation to the lingual nerve. The objective of this study was to test the hypothesis that those beneficial effects would be sustained over an 11-month period. STUDY DESIGN: The device was tested on a mixed sample of 94 patients with xerostomia in an open-label, uncontrolled, prospective multicenter trial. Statutory outcome assessments were done at 5th, 8th, and 11th months and analyzed by multiple comparisons. RESULTS: Improvements achieved at month 5 from baseline were sustained throughout the follow-up period for the primary outcome, xerostomia severity, and the secondary outcomes resting whole salivary flow rate, xerostomia frequency, oral discomfort, and difficulties in speech, swallowing, and sleeping. No significant side effects were detected. CONCLUSIONS: The beneficial effects of a removable intraoral electrostimulating device were sustained for an 11-month period.

- 2020
-
In: Oral surgery, oral medicine, oral pathology and oral radiology. - : Elsevier. - 2212-4403 .- 2212-4411. ; 129:5, s. 523-530
-
Journal article (peer-reviewed)abstract
- Objectives: The aim of this study was to map the vertical locations of calcified carotid plaques (CCPs), osseous anatomic structures, and calcified soft tissues in the area of the carotid artery, determine to what extent CCPs are superimposed on the cervical spine in coronal images, and analyze the differences between men and women.Study Design: Computed tomography angiography (CTA) scans of 79 patients were studied. CCPs were discovered in 152 of the total 158 neck sides. Evaluations were performed by using sagittal and coronal reformatted CTA images with maximum intensity projection.Results: Most of the calcified anatomic structures studied, including the carotid bifurcation, were found in close relationship to the level of the third and fourth cervical vertebrae. In the coronal view, all or most of the areas of the CCPs were superimposed on the cervical spine in 22 of 44 (50%) neck sides with CCP in women and in 37 of 108 (34.2%) in men (P = .070).Conclusions: The carotid bifurcation is in close proximity to various calcified anatomic structures. This should be taken into account when diagnosing CCPs in panoramic radiographs. In the coronal view, CCPs and the cervical spine are often superimposed; thus, coronal images are not recommended for confirmation of putative carotid calcifications diagnosed on the basis of panoramic radiographs.

In: Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology. - : Elsevier. - 2212-4403 .- 2212-4411.
-
Journal article (peer-reviewed)abstract
- Objective: The aim was to optimize diagnostics for carotid artery calcifications (CACs) on panoramic radiographs (PRs) to identify cardiovascular disease (CVD) by investigating how 4 defined CAC shapes are associated with ultrasound (US) findings indicating CVD. Study Design: The study included 414 participants (802 neck sides) from the Malmö Offspring Dental Study, examined with PRs. The PRs were assessed for CAC shapes stratified into 4 categories: single, scattered, vessel-width defining, and vessel-outlining. The carotid arteries were examined with US for signs of CVD: the presence of plaques, largest individual area of a plaque, number of plaques, and percentage reduction of the lumen. Associations between the different CAC categories and US characteristics were analyzed. Results: All categories of CAC were significantly associated with a higher degree of US findings indicating CVD compared with no CAC (P < .001). The most significant differences were found for vessel-outlining CAC, with the mean of the largest individual plaque area of 17.9 vs 2.3 mm2, mean number of plaques 1.6 vs 0.2, and mean percentage reduction of the lumen 24.1% vs 3.5% (all P < .001). Conclusions: Independent of shape, CACs detected on PRs were associated with a higher degree of US findings of CVD. This was most pronounced for vessel-outlining CAC. With refined differential diagnostics of CACs in PRs, dentists may contribute to improved identification of patients in need of cardiovascular prevention.

Comparison of absorbed doses and organ doses measured with thermoluminescent dosimeters and Gafchromic film for cone beam computed tomography examination of the posterior mandibular region in a head phantom
- 2023
-
In: Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology. - : Elsevier. - 2212-4403 .- 2212-4411. ; 136:6, s. 769-776
-
Journal article (peer-reviewed)abstract
- Objectives: We aimed to map the correlation between thermoluminescent dosimeters (TLDs) and Gafchromic film for measuring absorbed doses and to compare minimum, maximum, and mean absorbed doses over larger regions of interest and at various craniofacial organs and tissues during cone beam computed tomography (CBCT) exposure of the mandibular third molar region. Study Design: We positioned TLDs at 75 measurement points in a head phantom. Gafchromic film was cut to the same shape as the 5 levels of the phantom and was placed on top of the TLDs. Both dosimetry methods thus included the surface of each level simultaneously. CBCT scans were made using a 5 × 5 cm field of view and a rotation angle of 200°. Measurements included absorbed dose distributions, doses at all 75 points, and minimum, maximum, and mean doses within organs and tissues. Results: The correlation of point-dose measurements at all TLD sites with doses measured on film was strong (R2 = 0.9687), with greatest correlation at lower doses (<2 mGy). Large deviations between TLD and film measurements of minimum and maximum doses and absorbed doses to the organs occurred at all 5 levels. TLD positioning failed to cover several organ sites; for these, only absorbed dose measurements from the film were available. Conclusions: TLDs were unable to sample dose distributions and gradients accurately. The characteristics of Gafchromic LD-V1 film make it a favorable alternative in dental CBCT dosimetry.

- 2015
-
In: Oral surgery, oral medicine, oral pathology and oral radiology. - : Elsevier BV. - 2212-4403 .- 2212-4411. ; 120:2, s. 269-274

Journal article (peer-reviewed)abstract
- OBJECTIVE: To determine calcium volume in extirpated carotid plaques, analyze correlations between calcium volume and degree of stenosis, and analyze whether calcium volume influences the possibility of detecting stenosis in panoramic radiographs.STUDY DESIGN: Ninety-seven consecutive patients with ultrasonography-verified carotid stenosis were examined with panoramic radiography before surgery. Extirpated carotid plaques (n = 103) were analyzed for calcium volume by cone beam computed tomography (CBCT). Panoramic radiographs were analyzed for carotid calcifications.RESULTS: The median calcium volume was 45 mm(3) (first quartile subtracted from the third quartile [IQR], 14-98 mm(3)). We observed no correlation between calcium volume and degree of stenosis. Seventy-eight stenoses were situated within the region included in the panoramic radiographs, and their volumes ranged from 0 to 509 mm(3). Of these, 99% revealed carotid calcifications on panoramic radiographs.CONCLUSIONS: We found no association between calcium volume and degree of carotid stenosis. Calcium volume did not influence the possibility of detecting carotid calcifications in panoramic radiographs.

Association of high cardiovascular risk and diabetes with calcified carotid artery atheromas depicted on panoramic radiographs
- 2022
-
In: Oral surgery, oral medicine, oral pathology and oral radiology. - : Elsevier. - 2212-4403 .- 2212-4411. ; 133:1, s. 88-99
-
Journal article (peer-reviewed)abstract
- Objective: To evaluate whether estimates of risk of future cardiovascular events and death and established or unknown diabetes are significantly associated with calcified carotid artery atheromas (CCAAs) on panoramic radiographs (PRs). The main focus was on men and women without previous myocardial infarction (MI). Methods: The PAROKRANK (Periodontitis and its Relation to Coronary Artery Disease) study included patients with a first MI and matched control subjects. In this substudy, 738 patients (138 women) and 744 control subjects (144 women) with available PRs were assessed for CCAA. Cardiovascular risk estimates were determined according to the Framingham Risk Score (FRS) and Systematic COronary Risk Evaluation (SCORE). Established and previously unknown diabetes was also determined. Results: CCAA was detected on PRs in 206 control subjects (28%) and 251 patients (34%). FRS was significantly associated with CCAA among control subjects (P = .04) and patients (P = .001). SCORE was associated with CCAA among control subjects (P < .01) but not patients (P = .07). Among men, FRS and SCORE were associated with CCAA in both control subjects and patients. Diabetes was not significantly associated with CCAA after adjustments. Conclusions: Elevated cardiovascular risk scores were associated with CCAA on PRs among control subjects. Diabetes was not independently associated with CCAA, possibly owing to selection bias.

Bacterial diversity in medication-related osteonecrosis of the jaw
- 2017
-
In: Oral surgery, oral medicine, oral pathology and oral radiology. - : Elsevier. - 2212-4403 .- 2212-4411. ; 123:4, s. 436-444
-
Journal article (peer-reviewed)abstract
- Objective. The aim was to study the association between microflora and medication-related osteonecrosis of the jaw (MRONJ) by using culture-independent molecular techniques to detect bacteria in necrotic bone lesions. Study Design. Included were 18 consecutive patients with MRONJ, 10 with osteoporosis and 8 cancer patients. Bone biopsies were retrieved from the center of the necrotic bone and from visually healthy bone, and 16 S rRNA gene fragments from bacterial DNA were amplified with polymerase chain reaction. Results. The study revealed a diversity of bacteria represented by 16 S rRNA sequences in all the necrotic bone samples and in 60% of the visually healthy bone. Eight dominating taxa groups were identified at the genus level: Porphyromonas, Lactobacillus, Tannerella, Prevotella, Actinomyces, Treponema, Streptococcus, and Fusobacterium. Conclusions. The necrotic bone lesions contained mainly anaerobic bacteria, representative of periodontal microflora, suggesting that a periodontal infection in combination with antiresorptive treatment could initiate osteonecrosis.

Journal article (peer-reviewed)abstract
- OBJECTIVE: The aim of this study was to prospectively determine the incidence of medication-related osteonecrosis of the jaw (MRONJ) and define risk factors in patients with metastatic breast cancer treated with zoledronic acid and/or denosumab.STUDY DESIGN: In a prospective cohort study performed in Region Skåne, Sweden, from January 1, 2012, until December 31, 2015, all patients with breast cancer who had radiographic evidence of bone metastases and were treated with zoledronic acid or denosumab were included and followed up until May 31, 2018.RESULTS: Of the 242 patients, MRONJ developed in 16 (6.6%) during the 77 months of study. The incidence of MRONJ in patients treated with zoledronic acid was 4.1%, and in patients treated with denosumab, it was 13.6%. The risk of MRONJ was higher in patients on denosumab than in those treated with zoledronic acid (P = .011). Corticosteroid use was associated with a decreased risk of MRONJ (P = .008), and diabetes was associated with an increased risk of MRONJ (P = .02).CONCLUSIONS: The incidence of MRONJ is 6.6% (>3 times higher) in denosumab-treated patients with breast cancer compared with that in patients treated with zoledronic acid. Corticosteroid use decreased the risk of MRONJ.
