The effect of low-level laser therapy as an adjunct to non-surgical periodontal treatment on gingival crevicular fluid levels of transforming growth factor-beta 1, tissue plasminogen activator and plasminogen activator inhibitor 1 in smoking and non-smoking chronic periodontitis patients: A split-mouth, randomized control study


Abstract

Background and Objective

This study aimed to investigate the effects of low-level laser therapy (LLLT) as an adjunct to scaling and root planing (SRP) on smoking and non-smoking patients with chronic periodontitis.

Material and Methods

The study was conducted using a split-mouth design with 30 patients with chronic periodontitis (15 smokers, 15 non-smokers) and 30 healthy individuals matched for age, sex and smoking status as controls. Groups were constituted as follows: Cp+SRP+Sham: non-smokers with chronic periodontitis treated with SRP; Cp+SRP+LLLT: non-smokers with chronic periodontitis treated with SRP+LLLT; SCp+SRP+Sham: smokers with chronic periodontitis treated with SRP; SCp+SRP+LLLT: smokers with chronic periodontitis treated with SRP+LLLT; C: control group comprised of periodontally healthy non-smokers; SC: control group comprised of periodontally healthy smokers. LLLT was first applied on the same day as SRP and again on days 2 and 7 after SRP treatment. Clinical parameters were recorded before non-surgical periodontal treatment (baseline) and on day 30. Gingival crevicular fluid samples were collected before periodontal treatment (baseline) and during follow-up visits on days 7, 14 and 30. Gingival crevicular fluid transforming growth factor (TGF)-β1, tissue plasminogen activator (tPA) and plasminogen activator inhibitor 1 (PAI-1) levels were measured using enzyme-linked immunosorbent assay.

Results

All clinical parameters showed significant reductions between baseline and day 30 following SRP treatment in both the LLLT and sham groups (P<.001). No significant differences were observed between the LLLT and sham groups of either the smokers or non-smokers (P>.05). Gingival crevicular fluid PAI-1 levels decreased significantly in the SCp+SRP+sham and SCp+SRP+LLLT groups (P<.05), and gingival crevicular fluid tPA levels decreased significantly in the Cp+SRP+sham, Cp+SRP+LLLT and SCp+SRP+LLLT groups (P<.05). Gingival crevicular fluid TGF-β1 levels decreased significantly in all treatment groups (P<.05). Although no significant differences were found between the gingival crevicular fluid PAI-1, tPA and TGF-β1 levels of the LLLT versus sham groups (P>.05) at any of the time points measured, both LLLT groups showed significant reductions in tPA/PAI-1 ratios over time.

Conclusion

Within the limits of this study, LLLT may be understood to play a role in the modulation of periodontal tissue tPA and PAI-1 gingival crevicular fluid levels, particularly in smoking patients with chronic periodontitis, and may thus be recommended as an adjunct to non-surgical periodontal treatment.

Probiotics and oral health: A systematic review.

Med Oral Patol Oral Cir Bucal. 2017 Apr 8:0. [Epub ahead of print]

Abstract

BACKGROUND:

Probiotics are microorganisms, mainly bacteria, which benefit the host's health. Many studies support the role of probiotics as a contributor to gastrointestinal health, and nowadays many authors are trying to prove its influence in oral health maintenance.

OBJECTIVES:

To review the published literature with the purpose of knowing the importance of using probiotics as a preventive and therapeutic method for oral infectious diseases management.

MATERIAL AND METHODS:

An electronic search in PubMed database with the keywords "oral health AND probiotics AND dentistry" was conducted. The inclusion criteria were: randomized clinical trials (RCTs) that assess the action of any probiotic strain in the treatment and / or prevention of an infectious oral disease, RCTs that assess the action of any probiotic strain on counting colony forming units (CFU) of oral pathogens, systematic reviews and meta-analysis. The Jadad scale was used to assess the high quality of RCTs.

RESULTS:

Fifteen articles were considered for this review. Of which, 12 were RCTs of good / high quality (Jadad scale), two meta-analysis and one systematic review.

CONCLUSIONS:

The literature reviewed suggests probiotics usage could be beneficial for the maintenance of oral health, due to its ability to decrease the colony forming units (CFU) counts of the oral pathogens. However, randomized clinical trials with long-term follow-up periods are needed to confirm their efficacy in reducing the prevalence/incidence of oral infectious diseases. Furthermore, the recognition of specific strains with probiotic activity for each infectious oral disease is required, in order to determine exact dose, treatment time and ideal vehicles.

In-Office Application of Fluoride Gel or Varnish: Cost-Effectiveness and Expected Value of Perfect Information Analysis

Caries Res 2017;51:231-239


April 08, 2017 
 

Abstract

Application of fluoride gel/varnish (FG/FV) reduces caries increments but generates costs. Avoiding restorative treatments by preventing caries might compensate for these costs. We assessed the cost-effectiveness of dentists applying FG/FV in office and the expected value of perfect information (EVPI). EVPI analyses estimate the economic value of having perfect knowledge, assisting research resource allocation. A mixed public-private-payer perspective in Germany was adopted. A population of 12-year-olds was followed over their lifetime, with caries increments modelled using wide intervals to reflect the uncertainty of caries risk. Biannual application of FV/FG until age 18 years was compared to no fluoride application. Effectiveness parameters and their uncertainty were derived from systematic reviews. The health outcome was caries increment (decayed, missing, or filled teeth; DMFT). Cost calculations were based on fee catalogs or microcosting, including costs for individual-prophylactic fluoridation and, for FG, an individualized tray, plus material costs. Microsimulations, sensitivity, and EVPI analyses were performed. On average and applied to a largely low-risk population, no application of fluoride was least costly but also least effective (EUR 230; 11 DMFT). FV was more costly and effective (EUR 357; 7 DMFT). FG was less effective than FV and also more costly when using individualized trays. FV was the best choice for payers willing to invest EUR 39 or more per avoided DMFT. This cost-effectiveness will differ in different settings/countries or if FG/FV is applied by other care professionals. The EVPI was mainly driven by the individual's caries risk, as FV/FG were significantly more cost-effective in high-risk populations than in low-risk ones. Future studies should focus on caries risk prediction.

Effect of different composite core materials on fracture resistance of endodontically treated teeth restored with FRC posts

Journal of Applied Oral Science
Print version ISSN 1678-7757On-line version ISSN 1678-7765
J. Appl. Oral Sci. vol.25 no.2 Bauru Mar./Apr. 2017
http://dx.doi.org/10.1590/1678-77572016-0306 

Objective
This study evaluated the fracture resistance of endodontically treated teeth restored with fiber reinforced composite posts, using three resin composite core build-up materials, (Clearfil Photo Core (CPC), MultiCore Flow (MCF), and LuxaCore Z-Dual (LCZ)), and a nanohybrid composite, (Tetric N-Ceram (TNC)).

Material and Methods
Forty endodontically treated lower first premolars were restored with quartz fiber posts (D.T. Light-Post) cemented with resin cement (Panavia F2.0). Samples were randomly divided into four groups (n=10). Each group was built-up with one of the four core materials following its manufacturers’ instructions. The teeth were embedded in acrylic resin blocks. Nickel-Chromium crowns were fixed on the specimens with resin cement. The fracture resistance was determined using a universal testing machine with a crosshead speed of 1 mm/min at 1350 to the tooth axis until failure occurred. All core materials used in the study were subjected to test for the flexural modulus according to ISO 4049:2009.

Results
One-way ANOVA and Bonferroni multiple comparisons test indicated that the fracture resistance was higher in the groups with CPC and MCF, which presented no statistically significant difference (p>0.05), but was significantly higher than in those with LCZ and TNC (p<0 .05="" aligned="" flexural="" fracture="" from="" highest="" in="" loads.="" materials="" modulus="" of="" p="" ranking="" same="" tendency="" terms="" the="" values="" was="" with="">
Conclusion

Among the cores used in this study, the composite core with high filler content tended to enhance fracture thresholds of teeth restored with fiber posts more than others.

External and internal resin infiltration of natural proximal subsurface caries lesions: A valuable enhancement of the internal tunnel restoration

Quintessence Int 48 (2017), No. 5  (18.04.2017)

Page 357-368, doi:10.3290/j.qi.a37799, PubMed:28294198



Objective: The aim of this ex-vivo study was to evaluate both the external and the internal penetration ability of a resin infiltrant into natural proximal and macroscopically intact white spot lesions, and to merge this approach with the internal tunnel preparation concept.

Method and Materials: 20 premolars and 20 molars with proximal subsurface lesions (ICDAS, code 2) and respective radiographic lesion depths extending into the middle third of dentin (D2 lesions) were selected and divided into two groups. Treatment needs were confirmed using digital imaging fiber-optic transillumination and laser fluorescence. Deproteinization (NaOCl; 2%) followed, and lesions of Group 1 (control; n = 20) were etched (HCl; 15%) and externally infiltrated (Icon). Accordingly, the specimens of Group 2 (n = 20) were treated with the resin infiltrant from external; then, internal Class I tunnels were prepared, lesions were internally infiltrated (Icon), and the occlusal cavities were restored (G-ænial Flo X) after etching (H3PO4 gel; 40%). Teeth were cut perpendicular to the proximal lesion surfaces, and percentage infiltrations were analyzed using confocal laser microscopy and a dedicated image manipulation program (GIMP).

Results: Regarding the external infiltration, no differences between both groups were detected (P = .114; Mann-Whitney). Additional internal application of the resin infiltrant significantly increased the percentage amount of enamel lesion infiltration (P < .0001; Wilcoxon).

Conclusion: External and internal infiltration seem to complement the internal tunnel approach, thus remediating the drawbacks of the latter by occluding and stabilizing the porous areas of the proximal caries lesion, and preserving both the marginal ridge and the proximal contact area.

Dentsply Sirona Orthodontics announces the expansion of treatment indications for the MTM® (Minor Tooth Movement) Clear•Aligner. The clear aligner combines proven orthodontic techniques with advanced digital modeling to provide dental professionals with a streamlined solution for treating minor anterior misalignments.
MTM® Clear•Aligner is uniquely engineered to deliver the space and
force needed to accomplish tooth movement. The technology utilizes a proprietary “open pathway” architecture that allows teeth to move easily into the desired positions. Unlike other clear aligners, MTM® Clear•Aligner does not require clinicians to bond unsightly attachments to teeth, to accomplish movement. No attachments saves practice chair time and provides for a more esthetically pleasing treatment solution for the patient. To facilitate tooth movement MTM® Clear•Aligner uses integrated “force points”, programmed into the aligner, to provide a greater range of tooth movements, while making aligner placement and removal easy for the patient. 

MTM® Clear•Aligner targets the movement and positioning of the six most visible teeth, on both the upper and lower arches. These teeth are known as the social six. The aligner movements address tooth; spacing, tipping, torqueing, intrusion, extrusion, and rotation. Ideal candidates are those who are experiencing adult tooth crowding, orthodontic relapse, or those who seek cosmetic enhancements. Of the thousands of cases completed since the products’ launch, many dental professional note that most of their patients sought simply to improve their smile.
Brad Clatt, Group Vice President of Orthodontics states, “Whether a dental professional currently prescribes clear aligners, or has been waiting for an aligner system that better fits the needs of their patients, MTM Clear•Aligner is a simple solution to address one of the most common misalignments seen in adult patients today. Dentsply Sirona prides itself on keeping patient care, where it belongs, in the hands of the clinician, and offers each clinician a customized approach to treating their patients. MTM Clear•Aligner is a highly affordable solution for both doctor and patient, with the ability to move the social six to the desired position, creating the patient’s Ideal Smile.” 

To help offices get started with MTM Clear•Aligner, Dentsply Sirona Orthodontics offers an attractively-priced Welcome Kit that includes discounted patient cases, a web based training course, practice marketing and office integration resources. To learn more about the MTM Clear•Aligner visit the Dentsply Sirona booth #2414, during the American Association of Orthodontists (AAO), Annual Session.
