Assessment of tobacco dependence curricula in Italian dental hygiene schools
2013
The aim of this study was to assess the level of tobacco dependence education offered by Italian dental hygiene programs. A fifty-question survey was mailed to the thirty-one active public and private dental hygiene programs in Italy during the 2008-09 academic year. The survey assessed faculty confidence in teaching tobacco treatment, which courses contained tobacco dependence content, the number of minutes spent on specific content areas, and the level of clinical competence that dental hygiene graduates should be able to demonstrate. Surveys were returned by sixteen programs for a response rate of 52 percent. Respondents indicated tobacco dependence education was included in clinic or cl…
Oral colonization by Levilactobacillus brevis KABPTM-052 and Lactiplantibacillus plantarum KABPTM-051: A Randomized, Double-Blinded, Placebo-Controll…
2021
Background To determine the oral colonization capacity of the strains Levilactobacillus brevis KABPTM-052 (CECT 7480) and Lactiplantibacillus plantarum KABPTM-051 (CECT 7481) in healthy subjects. Material and methods This randomized, double-blinded, placebo-controlled study included 40 volunteers (22 females, 18 males; age range 18-55 years) with healthy gingiva or mild gingivitis, allocated to receiving probiotic chewing gum (n=20) or placebo (n=20) b.i.d for 6 weeks. At baseline and after 6 weeks of treatment, a periodontics specialist collected saliva samples to assess probiotic colonization by qPCR, and analysed dental plaque, gingival index and dental probing pocket depth in Community …
Alendronate-related oral mucosa ulcerations
2000
Alendronate is widely used in the treatment of osteoporosis and other bone diseases. Although it is considered a well-tolerated drug, there are numerous reports of adverse effects on the mucosa in the upper aerodigestive tract, with oesophagitis as the most common complication. The strict regulations for the proper administration of the drug indicate that these side effects might well be the result of a direct, irritant mechanism on the upper aerodigestive tract. We present two clinical cases of patients who developed extensive palatal ulcers as a result of taking alendronate. We discuss possible mechanisms implicated in the production of the ulcers and some clinical factors of interest.
Clinical evaluation of the Er:YAG laser in combination with an enamel matrix protein derivative for the treatment of intrabony periodontal defects: a…
2003
OBJECTIVES The aim of the present study was to compare the combination therapy of deep intrabony periodontal defects using an Er:YAG laser (ERL) and enamel matrix protein derivative (EMD) to scaling and root planing+ ethylenediaminetetraacetic acid (EDTA)+EMD. MATERIAL AND METHODS Twenty-two patients with chronic periodontitis, each of whom displayed 1 intrabony defect, were randomly treated with access flap surgery and defect debridement with an Er:YAG (160 mJ/pulse, 10 Hz) plus EMD (test) or with access flap surgery followed by scaling and root planing (SRP) with hand instruments plus EDTA and EMD (control). The following clinical parameters were recorded at baseline and at 6 months: plaq…
Root coverage with connective tissue graft associated with coronally advanced flap or tunnel technique: a randomized, double-blind, mono-centre clini…
2016
Aim: The aim of this randomized clinical trial was to compare the coronally advanced flap (CAF) with the modified microsurgical tunnel technique (MMTT) for treatment of Miller class I and II recessions. Material and Methods: Forty patients with 71 gingival recessions were recruited and randomly assigned to either CAF or to MMTT. In both groups, a connective tissue graft was applied. Clinical evaluations were performed after 3, 6, and 12 months. Impressions were taken and digitally scanned three-dimensionally to evaluate the quantitative soft tissue changes in the operative region. Patient satisfaction was measured with the root coverage aesthetic score (RES). Results: After a period of 12 m…
Bactericidal Effect of the Er:YAG Laser on Dental Implant Surfaces: An In Vitro Study
2002
The aim of the in vitro study was to examine the bactericidal effect of an Er:YAG laser on common dental implant surfaces.Seventy-two titanium platelets with 3 different surfaces--sandblasted and acid-etched (SA), titanium plasma-sprayed (TPS), and hydroxyapatite-coated (HA)--were incubated with a suspension of Streptococcus sanguinis (ATCC 10556). Irradiation at pulse energies of 60 and 120 mJ and a frequency of 10 pps was performed on a computer-controlled XY translation stage. After laser treatment the specimens were sonicated and the bacterial growth examined by counting colony forming units on blood agar plates. Temperature elevations during irradiation were investigated using K-type t…
In vitro and in vivo characterization of porcine acellular dermal matrix for gingival augmentation procedures
2013
Recently, porcine acellular dermal matrix (PADM) has been proposed as a possible alternative to autogenous grafts in periodontal plastic surgery. The aim of the present study was to investigate the in vitro responses of four different oral cell lines cultured on a novel PADM. Furthermore, tissue reaction to PADM was evaluated histologically after subcutaneous implantation in mice.Human gingival fibroblasts (HGF), human osteoblast-like cells, human umbilical vein endothelial cells and human oral keratinocytes (HOK) were cultured and transferred on to the PADM. A tissue culture polystyrene surface served as the control. The viability of all tested cell lines on PADM was measured by using the …
The effect of orally administered probiotic Lactobacillus reuteri -containing tablets in peri-implant mucositis: a double-blind randomized controlled…
2015
Background and Objectives Probiotics create a biofilm and protect the oral tissues against the action of periodontal pathogenic bacteria. The aim of this study was to evaluate the effects of the oral probiotic Lactobacillus reuteri Prodentis upon the peri-implant health of edentulous patients with dental implants and peri-implant mucositis, establishing comparisons vs implants without peri-implant disease. Material and Methods A double-blind, placebo-controlled, prospective cross-over study was made. The patients were all edentulous and were divided into two groups, (A) no peri-implant disease, and (B) peri-implant mucositis affecting one or more implants. Patients with peri-implantitis wer…
Epigenetics and periodontics : a systematic review
2019
Background Despite decades of research, our knowledge of several important aspects of periodontal pathogenesis remains incomplete. Epigenetics allows to perform dynamic analysis of different variations in gene expression, providing this great advantage to the static measurement provided by genetic markers. The aim of this systematic review is to analyze the possible relationships between different epigenetic mechanisms and periodontal diseases, and to assess their potential use as biomarkers of periodontitis. Material and Methods A systematic search was conducted in six databases using MeSH and non-MeSH terms. The review fulfilled PRISMA criteria (Preferred Reporting Items for Systematic re…
Oxidative stress in bisphosphonate-related osteonecrosis of the jaws
2013
Objectives To analyze whether oxidative stress (OS) changes are present in patients with bisphosphonate-related osteonecrosis of the jaw (BRONJ) versus controls. Materials and Methods Oxidative stress was analyzed in serum and unstimulated saliva of three groups: Group 1 consisted of 24 patients who had been treated with intravenous bisphosphonates (ivBPs) and developed BRONJ, group 2 consisted of 20 patients who had received ivBPs and did not develop BRONJ, and group 3 comprised 17 control subjects. Reduced glutathione (GSH), malondialdehyde (MDA), oxidized glutathione (GSSG), and 8–oxo-7,8-dihydro-2-deoxyguanosine (8-oxo-dG) levels, as well as the GSSG/GSH ratio, were measured. Results Me…
