Background. Thisstudy aimed to compare the effect of one and two sessions of antimicrobial photodynamic therapy (aPDT) as an adjunct to scaling and root planing (SRP) on clinical and microbial parameters in patients with chronic periodontitis. Methods. This study was conducted on 20 patients. The dental quadrants of patients were randomly assigned to SRP at baseline (group 1), SRP at baseline and one month (group 2), SRP plus aPDT at baseline (group 3) and SRP plus aPDT at baseline and one month (group 4). Probing depth (PD), clinical attachment level (CAL) gain, and bleeding on probing (BoP) were measured at baseline, and one and three months later. F. nucleatum counts were determined by PCR. ANOVA was used for the comparison of these variables between the groups. Results. In all the groups, PD reduction and CAL gain increased significantly at 1- and 3-month intervals compared to baseline (P=0.001). At three months, the difference in PD between groups 1 and 3 was statistically significant (P=0.014). CAL gain between groups 2 and 4 at one month (P=0.016) and three months (P=0.001) wasstatistically significant. Reduction in F. nucleatum counts was not significant between the four study groups (P>0.05). Conclusion. A combination of two sessions of aPDT and SRP could improve CAL gain; however, further long-term studies are necessary in this regard.

AbstractThe present clinical trial aimed to assess the effectiveness of antimicrobial photodynamic therapy versus Aloe vera gel as an adjunct to scaling and root planing on periodontal and microbial outcomes in patients with periodontitis. Eligible patients undergoing nonsurgical periodontal treatment were divided into 3 groups: group 1: antimicrobial photodynamic therapy; group 2: Aloe vera gel application; and group 3: scaling and root planing only. Clinical periodontal variables included the assessment of plaque scores, bleeding on probing, probing depth, and clinical attachment level gain. Plaque samples were collected to estimate microbial counts of Tannerella forsythia (T. forsythia) and Porphyromonas gingivalis (P. gingivalis). All measurements were recorded at baseline, 3 mo, and 6 mo. Statistical analysis of the given data was performed using the chi-squared test and ANOVA for clinical periodontal and microbiological data. Eighty-seven patients completed the trial. Bleeding on probing showed a significant reduction in group 2 compared with the other groups (p < 0.001). Group 1 showed a statistically significant reduction in probing depth and gain in clinical attachment level when compared to group 2 and group 3 (p < 0.05). Group 1 showed a statistically significant reduction in the counts of T. forsythia and P. gingivalis over a period of 3 mo (p < 0.05). The reduction was seen for T. forsythia only following 6 mo (p < 0.05). Group 2 showed a significant reduction for only T. forsythia at 3 mo (p < 0.05). Both antimicrobial photodynamic therapy and Aloe vera gel helped in reducing periodontal inflammation. Aloe vera gel showed additional benefit in reducing bleeding scores, while antimicrobial photodynamic therapy showed additional enhanced activity against periodontal pathogens and periodontal attachment level gain.

Aim. To compare the microleakage in class II composite restorations without a liner/with resin modified glass ionomer and flowable composite liner.Method. Forty standardized MO cavities were prepared on human permanent mandibular molars extracted for periodontal reasons and then divided into 4 groups of ten specimens. The cavity preparations were etched, rinsed, blot dried, and light cured and Adper Single Bond 2 is applied. Group 1 is restored with Filtek P60 packable composite in 2 mm oblique increments. Group 2 is precure group where 1 mm Filtek Z350 flowable liner is applied and light cured for 20 sec. Group 3 is the same as Group 2, but the liner was cocured with packable composite. In Group 4, 1 mm RMGIC, Fuji Lining LC is applied and cured for 20 sec. All the teeth were restored as in Group 1. The specimens were coated with nail varnish leaving 1 mm around the restoration, subjected to thermocycling, basic fuchsin dye penetration, sectioned mesiodistally, and observed under a stereomicroscope.Results. The mean leakage scores of the individual study groups were Group 1 (33.40), Group 2 (7.85), Group 3 (16.40), and Group 4 (24.35). Group 1 without a liner showed maximum leakage. Flowable composite liner precured was the best.

Oxidant Effect

Several studies have shown that some anti-oxidant natural compounds in combination with photodynamic therapy (PDT) can enhance the effectiveness of treatment. The aim of this study is to evaluate the effect of silymarin (SIL) in combination with 5,10,15,20-tetra-sulphonato-phenyl-porphyrin (TSPP) based photodynamic therapy, on experimental tumors. 30 Wistar rats with Walker carcinosarcoma, were divided into 6 groups: group 0 (control) — control, untreated group; group 1 (TSPP) — one dose of TSPP; group 2 (SIL) — silymarin; group 3 (PDT) — TSPP and irradiation 24 h after; group 4 (SIL[Formula: see text]PDT) — silymarin, TSPP and irradiation 24 h after; group 5 (SIL[Formula: see text]IR) and group 6 (IR) — irradiation and in addition, group 5 received SIL. Silymarin administered before photodynamic therapy decreased the lipid peroxidation ([Formula: see text] < 0.05) and modulated the antioxidant defense in tumor treated with PDT and silymarin suggesting that silymarin administration along with photodynamic therapy has an anti-oxidant effect. The caspase — 8 level and -3 activity increased in PDT and PDT [Formula: see text] SIL groups compared to the control; between the two groups there was a significant difference in term of apoptosis in favor to PDT. In conclusion, silymarin administration inhibited the reactive oxygen species generation and reduced the tumoral cells’ apoptosis, suggesting that natural compound administered before photodynamic therapy did not improve the therapy’s effect.

Aim. This study was aimed to determine the prevalence of Tannerella forsythia in subgingival plaque samples of chronic periodontitis patients having different level of periodontal destruction and to assess the effect of scaling and root planing (SRP) on prevalence of T. forsythia. Materials and Methods. Study included 3 groups: group 1 were healthy individuals, group 2 had periodontitis with probing depth ≤ 5 mm, and group 3 had periodontitis with probing depth > 5 mm. Subjects in groups 2 and 3 exhibited both healthy and diseased periodontal sites. Prevalence of T. forsythia was determined using polymerase chain reaction. Subjects in groups 2 and 3 received SRP and were reevaluated three months after SRP. Results. T. forsythia was not detected in group 1. It was found in diseased sites in 40% and 73.33% of patients from groups 2 and 3, respectively. It was also found in healthy sites in 6.67% and 13.33% of patients from groups 2 and 3, respectively. The detection frequency of T. forsythia after SRP was 6.67% and 13.33% in groups 2 and 3, respectively. Conclusion. The results indicate a possible association between periodontal disease and presence of T. forsythia. Also, the detection frequency of T. forsythia was reduced after SRP.

Drugs induced nephrotoxicity now considered as an essential reason for kidney failure. Aminoglycoside anti-infection agents, for example, gentamicin, which causes ototoxicity and nephrtotoxicity as a side effect , this research is centered around the utilization of natural materials as an antioxidants against the lethal oxidative activity that applied on the kidney cells ,the most imperative one of these materials is the honey. This work aimed to assess the defensive impact of citrus honey against the histopathological and biochemical harms of gentamicin induced nephrotoxicity .24 locally breed rabbits (Oryctolagus cuniculus) were used and divided into 4 study groups (6 rabbits per each group), group 1 received I.P daily dose of normal saline (control), group 2 received (80 mg/kg/day) I.P dose of gentamicin, group 3 received (80mg/kg/day) of gentamicin I.P dose in combination with oral dose of Citrus Honey625 mg/kg/day for 14 days and group 4 received (80mg/kg/day) of gentamicin I.P dose in combination with extra dose of Citrus Honey orally for 14 days. All animals (at 15th day) were anesthetized by ether and sacrificed; blood samples were gathered for the subsequent measurement of the serum creatinine, urea and albumin  while an isolated kidney was kept in 10 % of formaldehyde for the histopathological examination. The results demonstrated that gentamicin causes nephrotoxicity showen by elevation of serum level of creatinine, urea and  a decrease in the serum albumin. While the administration of honey in combination with gentamicin reduced the nephro-toxic effect of gentamicin that represented by a reduction of the serum creatinine and urea with improvement of the kidney histological findings.This study concluded that, honey decreased nephrotoxic effect of  gentamicin   http://dx.doi.org/10.25130/tjps.25.2020.001

Background: Social media has become a source of medical information. Cleft lip and palate is a visible congenital anomaly. The aim of the study was to analyze Instagram® posts on the topic of cleft lip. Methods: Instagram® posts with “#cleftlip” from March 2014–March 2017 were accessed. Separate lists of expressions (hashtags, meaningful words, words with emojis or emojis alone) were prepared for primary posts and for replies. Thirty expressions statistically most frequent in primary versus secondary posts and 30 in secondary versus primary posts were identified (Group 1) as well as 30 English words or hashtags (Group 2), non-English words or hashtags (Group 3) and emojis (Group 4). The frequencies of expressions were compared (Z-test for the difference of two population proportions). Results: There were 34,129 posts, (5427 primary posts and 28,702 replies), containing 62,163 expressions, (35,004 in primary posts). The occurrence of all expressions was 454,162, (225,418 in primary posts and 228,744 in replies). Posts with positive expressions such as “beautiful”, “love”, “cute”, “great”, “awesome” occurred more often than these with negative ones. In replies all emojis were positive. Conclusions: Numerous Instagram® posts referring to cleft lip are published and do provoke discussion. People express their solidarity and sympathize with persons affected by cleft.

Abstract Objectives The purpose of this in vitro study was to investigate the effects of different disinfection methods on microleakage of Class V Giomer restorations. Materials and Methods Class V cavity preparation was performed on 40 sound permanent central incisors. Class V cavities (3 x 2 x 2 mm) were prepared on the buccal surfaces of the selected teeth. The teeth were randomly divided into four groups, each to be disinfected with a different method: Group 1—Disinfection with 2% chlorhexidine, Group 2—Disinfection with 6% sodium hypochlorite, Group 3—Disinfection with erbium, chromium: yttrium-scandium-gallium-garnet laser, Group 4—Control (distilled water). BeautiBond adhesive and Beautifil II Giomer restoration materials were applied to all surfaces of the cavities after the disinfection of all groups. The teeth were thermocycled 5,000 times (5–55°C), and then were immersed in 0.5% methylene blue for 24 hours. After rinsing, the teeth were longitudinally sectioned and dye penetration was assessed under a stereomicroscope (40x) to evaluate microleakage. Statistical Analysis The results were statistically evaluated by using the Kruskal–Wallis and Mann–Whitney U tests. Results Statistically, no significant difference was found between all four groups (p > 0.05). There was no statistically significant difference in microleakage scores of study groups (p > 0.05). Also, the microleakage scores of the gingival margins were significantly higher than the incisal margins (p < 0.0001). Conclusions Application of the different cavity disinfectants has no effect on the microleakage of Class V Giomer restorations.

Purpose. Early diagnosis of keratoconus disease (KCN) is the first priority in the preoperative evaluations of refractive surgery (RS).The aim of this study was to investigate the correlation between findings of Belin Ambrosio enhanced ectasia display (BAD) software and conventional corneal imaging (Orbscan and topography) in the early diagnosis of KCN. Methods. For conducting this cross-sectional study, a total of 1000 eyes were selected from 500 patients that underwent the myopic photorefractive keratectomy surgery and were compared in four study groups during the years 2017–2018. In group 1, all topography, Orbscan, and BAD criteria were normal (65.8%).In contrast, in Group 2, at least one of the topography or Orbscan criteria as well as at least one BAD criterion (12.6%) were abnormal. In Group 3, the eyes had normal Orbscan and topography criteria with at least one abnormal BAD criterion (18.5%). Also, in Group 4, the patients had at least one abnormal Orbscan or topography criterion, but all BAD criteria (3.1%) were normal. Thickness of the thinnest point (TP) of cornea was compared in Pentacam and topography. Data analysis was done by SPSS software (version 21). Results. BAD criteria were normal in 78.5% of all eyes with normal topography and Orbscan criteria (specificity). BAD criteria were also abnormal in 80.2% of eyes (sensitivity). There was also no significant difference between TP in Orbscan and Pentacam. Conclusions. BAD criteria had a relatively acceptable sensitivity and specificity, compared with conventional Orbscan and topography criteria. Thus, BAD criteria can be more effective in the early diagnosis of KCN.
