BACKGROUND: Increasing evidence implicates biofilms, consisting of species such as Porphyromonas gingivalis, in the etiology of peri-implantitis. Multiple approaches to ablate biofilms on failing implants have been proposed, include the use of lasers; most recently the Er,Cr:YSGG laser. The purpose of this study is to establish an in-vitro single-species biofilm model on implant surfaces and determine power settings of the Er,Cr:YSGG laser that remove the biofilm while not causing physical damage to the disk...

BACKGROUND: The aim was to unravel how the air-polishing behaves on a titanium surface by evaluating the size and the shape of the cleaned area, influence of the different device settings, and pocket depths and cleaning movements. METHODS: 48 titanium SLA surface film-coated discs were treated with an air abrasive system using a subgingival plastic nozzle. Two subgingival models were employed: open-ended (step 1) and defined-size (step 2). In step 1, the most effective parameters were investigated by 5 sec static applications under different settings...

David Polak, Oren Ferdman, Yael Houri-Haddad
BACKGROUND: Porphyromonas gingivalis capsule enables evasion from phagocytosis, invasion of keratinocytes and bacterial survival. In mixed infection, the capsule also participates in coaggregation, which may lead to characteristic virulence not present in the mono-infection. The aim of the study was to evaluate the role of P.gingivalis capsule as a virulence factor in co-aggregated mixed infection with Fusobacterium nucleatum. METHODS: Mixed infections containing F...

BACKGROUND: A possible association between periodontitis and obstructive sleep apnea (OSA) has been suggested. The aim of this study was to compare periodontitis prevalence between control and OSA patients by assessing clinical periodontal parameters and the levels of gingival crevicular fluid (GCF) interleukin-1 beta (IL-1β), tumor necrosis factor alpha (TNF-α), high-sensitive C-reactive protein (hs-CRP) and serum hs-CRP. METHODS: A case-control study was performed that included 163 individuals: 83 individuals (18 females; 65 males) with OSA and 80 non-OSA individuals (23 females; 57 males) as controls...

BACKGROUND: Statins have been widely used to treat hypercholesterolemia. In addition to the inhibition of cholesterol synthesis, recent reports suggest bone anabolic property of statins. However, little notice has been paid to the direct effect of statins on osteoclastogenesis and bone resorption. METHODS: The effect of fluvastatin on osteoclast differentiation was determined using in vitro culture of mouse bone marrow macrophages (BMMs) in the presence of macrophage colony-stimulating factor (M-CSF) and receptor activator of nuclear factor kappa B ligand (RANKL)...

BACKGROUND: Peri-implantitis represents a disruption of the biocompatible interface between the titanium (Ti) dioxide layer of the implant surface and the peri-implant tissues. Increasing preclinical data suggest that the peri-implantitis microbiota not only triggers an inflammatory immune response but also causes electrochemical alterations of the Ti surfaces, i.e. corrosion, that aggravate this inflammatory response. Thus, we hypothesized that there is an association between the dissolution of titanium from dental implants, which suggests corrosion, and peri-implantitis in humans...

BACKGROUND: Periodontal wound healing has been accelerated by different low-level laser therapy (LLLT) protocols. However, just few studies evaluated the use of this therapy as adjunctive for periodontal plastic surgery procedures. The present study shows a 2-year result of connective tissue graft associated with LLLT in the treatment of gingival recession defects. METHODS: Forty patients presenting Miller Class I and II gingival recessions were previously treated by: Connective tissue graft (Control group, n = 20) or Connective tissue graft + LLLT (Test group, n = 20)...

BACKGROUND: Controversy exists as to possible correlation of periodontal disease with rheumatoid arthritis and ankylosing spondylitis. Confounding factors may relate to stringency of inflammatory disease diagnosis and to effect on periodontal disease of therapeutic intervention for rheumatoid arthritis. These were investigated. METHODS: Forty-five individuals with documented rheumatoid arthritis, spondyloarthropathy and calcium pyrophosphate deposition disease were examined from the Hamann-Todd collection of human skeletons compiled between 1912 and 1938, in addition to fifteen individuals contemporarily incorporated in the collection were examined for tooth loss, cavity occurrence, average and maximum lingual and buccal depth of the space between tooth and bone, periosteal reaction, serpentine bone resorption, abscess formation and root penetration of bone surface and analyzed by analysis of variance (ANOVA)...

BACKGROUND: To date, limited evidence is available specifically evaluating ridge preservation (RP) and implant placement in molar sites. The primary aim of this study was to radiographically compare alveolar ridge changes with and without RP with cone-beam computed tomography (CBCT). METHODS: This parallel, two-arm RCT included forty patients evenly distributed between two treatment groups. Following molar extraction, sites were allowed to heal naturally or received RP with freeze-dried bone allograft covered by a non-resorbable dense polytetrafluoroethylene (dPTFE) membrane...

BACKGROUND: Peri-implantitis is a complex polymicrobial biofilm-induced inflammatory osteolytic gingival infection that results in orofacial implant failures. There are no preclinical in vivo studies in implant dentistry that have investigated the inflammatory response to known microbial biofilms observed in humans. The aim is to develop a novel peri-implant rat model using an established model of polymicrobial periodontitis. METHODS: Wistar rats were used for the study of experimental peri-implantitis...

Roger P Levin
While getting patient reviews posted on online sites appears problematic for periodontal practices, the author urges periodontists to encourage their patients to review their practices online on Yelp and other sites. The more positive online reviews practices receive, the higher the rankings on review sites, which will translate into more website visits and, ultimately, more new patient appointments.

BACKGROUND: Previously published research for a single metropolitan market (Austin, Texas, USA) found that periodontists fared poorly on the Yelp website in regards to nearly all measured metrics including average star ratings, number of reviews, review removal rate, and evaluations by Elite Yelp users. The purpose of the current study was to confirm or refute these findings by expanding the data sets to additional metropolitan markets of varying sizes and geographic locations. METHODS: A total of 6,559 Yelp reviews were examined for general dentists, endodontists, pediatric dentists, oral surgeons, orthodontists, and periodontists in small (Austin, Texas), medium (Seattle, Washington), and large (New York City, New York) metropolitan markets...

OBJECTIVE: The collection of subgingival plaque samples with paper points is time-consuming and accident-sensitive. The collection of saliva, however, is simple and contains pathogens of all intraoral surfaces. The aim of this study is to investigate whether sampling with a mouthrinse (mouthrinse sample/MSP; test) leads to comparable results as the standard sampling method (multiple site test from the deepest pocket of each quadrant/MT4; control). METHODS: In 50 patients with periodontitis, subgingival plaque was sampled from the deepest pocket of each quadrant by using paper points and by gaining saliva with a saline mouthrinse...

BACKGROUND: The use of statins on adult chronic patients showed a positive effect on their periodontal status. However, The effect of locally delivered statins on periodontal treatment has not yet been systematically analyzed. Hence, the present systematic review and meta-analyses aimed to evaluate the efficacy of statins on treating localized periodontal intrabony defects. MATERIAL AND METHODS: An electronic search of 3 databases (1965-2016 March 1(st)), including PubMed, Embase, CINAHL, and a hand search of peer-reviewed journals for relevant articles were performed...
