Photodynamic therapy for the treatment of peri-implant diseases: A network meta-analysis of randomized controlled trials

Background Photodynamic therapy in peri-implantitis has been tested in randomized clinical trials. Though systematic review and meta-analysis on human and animal studies, identifies the utility of photodynamic therapy, a comparison of other interventions with photodynamic therapy for peri-implantitis does not exist. Hence the aim of this network meta-analysis is to identify the role of photodynamic therapy for peri-implantitis compared with other interventions tested in randomized human clinical trials. Method Randomized controlled trials comparing photodynamic therapy and other interventions in patients with peri- implantitis was searched for in electronic databases. The risk of bias was calculated using Cochrane risk of Bias tool. The heterogeneity between the studies in direct comparison was assessed using Chi-square and I2 tests. GRADE working group approach was used to assess the quality of evidence. Publication bias was assessed using Funnel plot and Trim and Fill method was used to identify the number of missing studies. Results We observed a significant reduction in the level of attachment scores with the use of combined photodynamic therapy with mechanical debridement when compared with other interventions tested. For bleeding on probing, pocket depth and plaque scores no statistically significant results were obtained. Conclusion The use of photodynamic therapy with mechanical debridement will definitely bring about significant improvement in patients with peri-implantitis. Further trials on the use of photodynamic therapy with other treatment modalities need to be tested to arrive at the best possible treatment option for peri-implantitis.

1,2-Didehydrophenothiazines: Preparation of 1-Alkyl and 1-Aryl-substituted Phenothiazines by Lithium-directed Alkylation

A general route to 1-alkyl substituted phenothiazines is described.Reactions of 2-chlorophenothiazine with an excess of methyl-, n-butyl-, s-butyl-, t-butyl- or phenyl-lithiums give the corresponding 1-substituted phenothiazines via 10-lithio-1,2-dehydrophenothiazine.Attempts to trap the presumed 1,10-dilithio intermediate failed.The reaction of 1-chlorophenothiazine with s-butyl-lithium results in preferential metallation of the 9-position. 2-Chlorophenothiazine reacts with nitrogen nucleophiles (lithium dialkylamides) to give 2-substituted products.

Studies on Diamagnetic Susceptibility of Biologically Active Heterocycles. 1. Diamagnetic Susceptibility of Phenothiazines

Diamagnetic susceptibilities for a number of phenothiazines are reported.A theoretical method to estimate the diamagnetic susceptibility of these biologically active heterocycles is presented.Phenothiazines have been considered to be composed of two units: one consisting of a benzene nucleus containing amino and thio groups at ortho positions to the substituents and the other consisting of a benzene ring with substituents.The diamagnetic contributions of these two units have been obtained from the diamagnetic susceptibilities of substituted o-aminobenzenethiols and benzenes and have been used in estimating the diamagnetic susceptibilities of phenothiazines.It has provided excellent theoretical results.Such an excellent agreement between measured and estimated values is due to the fact that the interactions between substituents which affect the diamagnetism have been duly accounted for in such calculations.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 1910-85-6, you can also check out more blogs aboutProduct Details of 1910-85-6

Mass Spectral Fragmentation Patterns of Heterocycles. VII. Reinvestigation of Fundamental Processes in Phenothiazines

Electron impact induced fragmentation patterns of simple phenothiazines have been reinvestigated using metastable ion studies, exact mass measuremants and deuterated derivatives.Secondary fragmentation processes involving ions m/e 198, 171, 167, 166, 154, 140 and 139 have been clarified.Mechanisms for the release of sulfur (SH. and CSH.) nitrogen (HCN and H2CN.) containing fragments from phenothiazine molecular ion are proposed based on the deuterium content of the daughter ions obtained from 1,9-dideuteriophenothiazine.A revised mechanism for the expulsion of ketene from 10-acetylphenothiazine is suggested based on the fragmentation pattern of the 1,9-dideuterioderivative.The composition of m/e 140 was determined by high resolution measurement to be C10H6N and not C11H7 as previously reported.

The effects of repeated applications of antimicrobial photodynamic therapy in the treatment of residual periodontal pockets: a systematic review

The aim of this study was to assess the effects of repeated applications of antimicrobial photodynamic therapy (aPDT) on the non-surgical periodontal treatment of residual pockets. This work was performed and reported according to the Cochrane and PRISMA recommendations, respectively, and registered at the PROSPERO registry (number CRD42017058403). An extensive search of the biomedical literature was conducted on four databases from January 1960 to August 2018, followed by hand searching. Analysis of the quality of the selected studies was based on the risk of bias. Only two randomised controlled clinical trials (RCTs) met the inclusion criteria although they had unclear risk of bias. One study showed that repeated applications of aPDT in association with conventional non-surgical treatment during periodontal maintenance improved all clinical outcomes after 6?months. The other study, which assessed the effects of repeated applications of aPDT in association with ultrasound debridement on periodontal pathogens, showed no significant reduction of the main pathogens after 3?6?months but reported reductions of probing pocket depth and C-reactive protein after 3 and 6?months, respectively, compared to mechanical therapy alone. Concluding, it was not possible to state that repeated applications of aPDT, in association with non-surgical treatment of residual pockets, have effective clinical effects in the periodontal maintenance therapy. Although one can consider that aPDT is a promising adjuvant therapy, it is still necessary to carry out more RCTs with low risk of bias in order to confirm or refute the benefits of multiple applications for residual periodontal pockets.

REACTION OF CHLORO DERIVATIVES OF 10-BENZYL- AND 10-(4′-FLUOROBENZYL)PHENOTHIAZINES WITH NITRILES AND AMINES UNDER ARYNE-FORMING CONDITIONS

2-Chloro-10-benzylphenothiazine (1) and 2-chloro-10-(4′-fluorobenzyl)phenothiazine (2) react with aliphatic nitriles (3 and 4) and LDA to yield typical 2-substituted aryne products (9a,b and 9g,h, respectively).However, treatment of 1 with aromatic nitriles (5-8) and LDA supplies 2-(arylmethyl)-1-cyano rearranged nitriles (10c-f), whereas 2, when treated similarly, affords both rearranged nitriles (10i-l) and typical 2-arylated nitrile products (9i-j).An explanation in terms of the effect of substituents on the competing aryne and tandem addition-rearrangement pathways is presented.The crystal structure of one of the rearranged 1-cyanophenothiazines (10c) was obtained and reveals that the molecule adopts the “extra” conformation in which the 10-benzyl group is in the pseudo axial position.The reaction of 1 and 2 with various lithium amides in the corresponding free amine solvents gives the corresponding 2-aminated products (11) and (12) in excellent yields.Both 1-chloro-10-benzylphenothiazine (18) and 1 supply the same product, 10-benzyl-2-N,N-diisopropylaminophenothiazine (11a), when made to react with LDA in diisopropylamine solvent, indicating that each of these reactions proceeds via the same aryne intermediate, and not through the SRN1 mechanism.

Adjunctive application of antimicrobial photodynamic therapy in the prevention of medication-related osteonecrosis of the jaw following dentoalveolar surgery: A case series

Background: Medication-related osteonecrosis of the jaw (MRONJ) is a debilitating complication strongly associated to antiresorptive agents. The present study aimed to describe the use of antimicrobial photodynamic therapy (aPDT) in the prevention of MRONJ. Methods: The sample consisted of 11 non-oncologic osteoporotic subjects in therapy with non-intravenous antiresorptive agents, requiring tooth extractions and/or implant removal. After minimally invasive surgical extractions, each alveolar socket was debrided and bony edges were smoothened. At this point, aPDT was performed using methylene blue-based phenothiazine chloride dye irradiated with a hand-held 100 mW diode laser with a wavelength of 660 ¡À 10 nm. Flaps were sutured to achieve first intention closure. Soft tissue healing was promoted with weekly applications of low-level laser therapy for 6 weeks. Recall visits were scheduled weekly for the first two months and monthly thereafter up to 6 months. At the 6-month appointment, healing was assessed clinically and radiographically. Results: A total of 62 surgical extractions were performed in both jaws, including 51 natural elements and 11 dental implants. No intraoperative complications were observed. Immediate post-operative period was generally uneventful except for mild pain and ecchymosis that occurred rarely and resolved spontaneously. Healing proceeded uneventfully, with no clinical or radiological prodromal manifestations of MRONJ up to the latest follow-up visit. Conclusions: aPDT might constitute a promising preventive treatment to reduce the risk of MRONJ in non-oncologic osteoporotic patients treated with non-intravenous antiresorptive agents that underwent dentoalveolar surgery.

Clinical effects of photodynamic therapy as an adjunct to full-mouth ultrasonic scaling and root planing in treatment of chronic periodontitis

Background and aims: Photodynamic therapy (PDT) is a potential strategy to eliminate infection in the specific tissue. It uses lower-power laser to activate a photosensitizing agent. Studies have shown the benefit of PDT in the periodontal treatment. The aim of this study was to evaluate the periodontal changes after applying PDT as an adjunct to one visit full-mouth SRP (scaling and root planing) with subgingival piezoelectric ultrasonic scaler compared with full-mouth SRP alone. Methods: A split-mouth randomized clinical trial was designed. Twenty patients with moderate to severe chronic periodontitis were treated with subgingival piezoelectric ultrasonic device alone in control group and adjunct treated with PDT in the test group. Probing pocket depth (PD), clinical attachment level (CAL), plaque index (PI), gingival bleeding index (GBI) and gingival inflammation index (GI) were evaluated at baseline, 1 month, 3 and 6 months after treatment. Only sites with PD ? 4 mm at baseline were calculated. Results: All periodontal parameters were significantly improved in both groups at 1 month, 3 and 6 months after treatment. All parameters in test group were better than that control group, with statistically significant differences of GBI and GI (P < 0.05) at 3 and 6 months after treatment but no statistically significant differences of PD, CAL and PI. Conclusions: One visit full-mouth ultrasonic SRP seems to have good enough effort for the periodontal status till 6 months. The adjunct treatment of PDT provided positive effect in term of GBI and GI.

Bactericidal efficacy of photodynamic therapy against Enterococcus faecalis in infected root canals: A systematic literature review

Objective: The aim was to review the bactericidal efficacy of photodynamic therapy (PDT) against Enterococcus faecalis (E. faecalis) in infected root canals. Methods: To address the focused question “Does PDT exhibit bactericidal effects against E. faecalis in infected root canals?” PubMed/Medline and Google-Scholar databases were searched from 1985 up to August 2013 using various combinations of the following key words: “antibacterial; “bactericidal; “endodontic; “root canal” and “photodynamic therapy”. Original studies, experimental studies and articles published only in English language were included. Letters to the editor, historic reviews and unpublished data were excluded. The pattern of the present review was customized to primarily summarize the pertinent information. Results: Seventeen studies (16 ex vivo and one in vivo) were included. In these studies, numbers of teeth used ranged between 30 and 220 teeth. In these studies, wavelengths of diode laser used, diameter of fiber and power output ranged between 625 and 805. nm, 200. mum and 0.4. cm, and 40. mW and 5. W respectively. Twelve studies reported PDT to be effective in eliminating E. faecalis from infected root canals. Four studies reported conventional irrigation and instrumentation to be more efficient in killing E. faecalis than PDT. One study reported PDT and conventional endodontic regimes to be equally effective in eliminating E. faecalis from infected root canals. In most studies, toluidine blue and/or methylene blue were used as photosensitizers. Conclusion: Efficacy of PDT in eliminating E. faecalis from infected root canals remains questionable.

Antimicrobial efficacy of photodynamic therapy and light-activated disinfection on contaminated zirconia implants: An in vitro study

Background: We aimed to evaluate the antimicrobial efficacy of photodynamic therapy (PDT) and light-activated disinfection (LAD) on zirconia dental implants contaminated with three bacterial species and investigate if the PDT and LAD cause implant surface alterations. Methods: Seventy-two zirconia dental implants were contaminated with a bacterial suspension of Prevotella intermedia, Actinomyces actinomycetemcomitans, and Porphyromonas gingivalis. The implants were subsequently randomly divided into four groups (n = 12 dental implants/each) according to the decontamination protocol: Group 1 (PDT1) ? PDT (660 nm, 100 mW) with toluidine blue; Group 2 (PDT2) ? PDT (660 nm, 100 mW) with phenothiazine chloride dye; Group 3 (LAD) ? light emitting diode (LED) with toluidine blue; and Group 4 (TB) ? toluidine blue without the application of light. Implants in the positive control (PC) group were treated with a 0.2% chlorhexidine-based solution, and implants assigned to the negative control (NC) group did not undergo any treatment. Each implant was then placed in tubes containing phosphate buffered saline (PBS) and vortexed for 60 s to remove the remaining bacteria from the implant surface. After 10-fold serial dilutions, 30 mul of the suspension was plated on Brucella agar plates. After 72 h, the colony forming units (CFU) were counted. Distinctive colonies were confirmed with MALDI Biotyper. The implants were analyzed using scanning electron microscope (SEM) to evaluate the possible surface alterations due to PDT or LAD. Results: All study groups had significant reductions in the number of CFUs compared with the NC (p < 0.05). PDT1, the PDT2, and the LAD groups had the largest bacterial reduction with respect to each bacterial species separately and the total bacterial count, and they were more efficient compared with the TB group (p < 0.05). SEM analysis did not reveal any alterations of the implant surface after the treatment procedures. Conclusion: Both PDT protocols and LAD showed high and equal effectiveness in decontamination of zirconia dental implants.
