Effects of ultrasonically activated irrigants with or without surfactant on smear layer removal after post space preparation

The aim of this study was to compare the effects of different NaOCl and EDTA formulations with/without ultrasonic use on smear layer removal and root canal surface characteristics after post space preparation. Study design: After post space preparations, forty-six teeth were subjected to different post space irrigation regimes; G1, 17% EDTA; G2, 17% EDTA+Ultrasonic activation; G3, EDTA-T; G4, EDTA-T+Ultrasonic activation; G5, NaOCl; G6, NaOCl+Ultrasonic activation. Specimens were examined under scanning electron microscope and scored for debris and smear layer removal and dentinal tubule opening and statistically analyzed with Kruskal Wallis and Dunn's test. Significance value was set at p<0.05. Results: EDTA and EDTA-T groups showed significantly better efficiency than the other groups in the each parts of the samples in terms of smear layer removal (p<0.05). In terms of dentinal tubule opening, EDTA, EDTA+Ultrasonic and EDTA-T groups had significantly better efficacy than the other groups in the middle and coronal parts of the samples (p<0.05). Conclusions: Ultrasonic activation did not significantly improve the efficiency of the irrigants

The effectiveness of various chelates used alone or in combination with sodium hypochlorite in the removal of calcium hydroxide from root canals

Aim: To evaluate the effectiveness of various chelates used alone or in combination with sodium hypochlorite (NaOCl) in the removal of calcium hydroxide (Ca(OH)2 ) from root canals. Materials and Methods: The root canals of 72 mandibular incisors were prepared up to the ProTaper F2 file. Among these, six randomly selected teeth were used as negative and positive controls, while the root canals of the remaining 66 were filled with Ca(OH)2 paste for 1 week. Then, the experimental group specimens were divided into six groups (n = 11). The access cavities were reopened and the Ca(OH)2 paste in each group was removed using the following solutions: 2.5 mL ethylenediaminetetraacetic acid (EDTA; Group 1), 2.5 mL peracetic acid (PAA; Group 2), 2.5 mL QMix (Group 3), 2.5 mL NaOCl/2.5 mL EDTA (Group 4), 2.5 mL NaOCl/2.5 mL PAA (Group 5), and 2.5 mL NaOCl/2.5 mL QMix (Group 6). Digital photographs of longitudinally split specimens were imported into image analyzer software, and the amount of residual Ca (OH) 2 was recorded as a percentage of the overall canal surface area. The results were analyzed using Kruskal–Wallis and Conover–Dunn tests. Results: The canal walls in the positive control group were completely covered with Ca(OH) 2 compared with those in the negative control group. The lowest Ca(OH)2 removal efficiency was observed for Group 4 (P < 0.001), while Group 6 showed favorable results (P < 0.05). Conclusions: QMix combined with NaOCl can remove Ca(OH)2 from root canals as effectively as 17% EDTA and 1% PAA. The type and sequence of irrigants are more important than the total irrigant volume for effective Ca(OH) 2 removal

Efficacy Of Rotary Ni-Ti Retreatment Systems In Root Canals Filled With A New Warm Vertical Compaction Technique

The aim of this study was to compare the efficacy of Mtwo, Pro Taper retreatment files and Hedstrom files for the retreatment of root canals filled with Bee Fill 2 in 1 and cold lateral compaction techniques. 63 single-rooted human teeth were prepared with Mtwo rotary files to size 35/.04 and assigned into three groups (n=21/group). (1) Bee Fill 2 in1/2Seal, (2) Bee Fill 2 in 1/AH26 and (3) laterally-compacted gutta-percha/AH26. The specimens were subgrouped according to the file system used to remove root fillings (n=7/subgroup): 1. Mtwo retreatment file, 2. Pro Taper retreatment file, 3. Hedstrom file. Roots were split longitudinally and photographed. The time required for removal of root canal fillings and the areas of residual root filling materials were compared statistically (p<0.05). The maximum amount of remnant was observed in the Mtwo group for removal of BeeFill 2 in1/AH26. ProTaper retreatment files required less time to remove root filling material than Mtwo retreatment files and Hedstrom files (p<0.05). Among the tested removal systems. ProTaper retreatment files may offer the best efficiency-speed combination.WoSScopu

The effectiveness of a pictorial asthma action plan for improving asthma control and the quality of life in illiterate women

Background: Written asthma action plans are an important part of asthma management, but cannot be used for illiterate people. Objective: The aim of this study was to establish the effectiveness of a pictorial asthma action plan on asthma control, health-related quality of life (HRQoL), and asthma morbidity in a population of illiterate women with asthma. Methods: Forty illiterate women with moderate-severe persistent asthma were assigned alternatively to receive either asthma education alone (control group) or asthma education and a pictorial asthma action plan (study group). Asthma control was assessed using the asthma control test (ACT), HRQoL was assessed using the St George's Respiratory Questionnaire (SGRQ), and the frequency of non-scheduled hospital or emergency visits was monitored. Results: Thirty-four patients completed the study. The ACT and SGRQ scores of both groups improved at every follow-up time point compared with baseline (p < 0.001). The ACT scores at 1 month (22.44 versus 20.75, p = 0.034) and 2 months (23.28 versus 21.81, p = 0.010) were higher in the study group than in the control group, but this was not maintained at 6 months (24.00 versus 23.25, p = 0.069). The SGRQ scores at 6 months were better in the study group (18.12) than in the control group (23.96, p = 0.033). No hospital admissions were recorded for either group. Conclusion: Education provides a significant improvement in asthma control and HRQoL while managing illiterate asthma patients, additionally the pictorial asthma action plan can be a helpful tool for self-medication

‘Amara – Introduction

‘Amara est le dernier faubourg nord de la ville dans la continuité des faubourgs de Souk Sarouja et de ‘Uqayba. Ses limites sont à l’ouest le mur du cimetière Dahdah, au nord le boulevard de Bagdad, au sud l’axe de Souk Sarouja et l’avenue Malik Fayçal et à l’est, en 1930, les jardins de l’oasis. À la même époque, le boulevard de Bagdad qui a été tracé quelques années auparavant n’est toujours pas urbanisé, il joue plutôt le rôle de voie périphérique isolant la ville de l’oasis.

Amyloidosis in a Patient With Congenital Neutropenia Because of G6PC3 Deficiency

Glucose-6-phosphatase catalytic subunit 3 (G6PC3) deficiency is a recently identified form of congenital neutropenia associated with developmental anomalies. The severity of neutropenia and the clinical spectrum are highly variable. Aside from infectious complications and extrahematologic features, inflammatory bowel disease and autoinflammatory complications are less frequently observed manifestations. However, amyloidosis has never been reported in G6PC3 deficiency. Here, we present a 12-year-old patient with incidentally discovered neutropenia because of the p.E65A (c.194A>C) variant of the G6PC3 gene. He had recurrent aphthae and abdominal pain episodes, and developed nephrotic-range proteinuria, amyloidosis, and end-stage renal failure during follow-up

Effects of biomass smoke on pulmonary functions: a case control study

Background: Biomass smoke is the leading cause of COPD in developing countries such as Turkey. In rural areas of Turkey, females are more exposed to biomass smoke because of traditional lifestyles. Aim: The aim of this study was to determine the adverse effects of biomass smoke on pulmonary functions and define the relationship between duration in years and an index (cumulative exposure index) with altered pulmonary function test results. Participants and methods: A total of 115 females who lived in the village of Kagizman (a borough of Kars located in the eastern part of Turkey) and were exposed to biomass smoke were included in the study. The control group was generated with 73 individuals living in the same area who were never exposed to biomass smoke. Results: Twenty-seven (23.8%) females in the study group and four (5.5%) in the control group had small airway disease (P=0.038). Twenty-two (19.1%) females in the study group and ten (13.7%) in the control group had obstruction (P=0.223). Twenty (17.3%) females in the study group who were exposed to biomass smoke had restriction compared with ten (13%) in the control group (P=0.189). The duration needed for the existence of small airway disease was 16 years, for obstructive airway disease was 17 years, and for restrictive airway disease was 17 years. The intensity of biomass smoke was defined in terms of cumulative exposure index; it was calculated by multiplying hours per day, weeks per month, and total years of smoke exposure and dividing the result by three. Conclusion: Exposure to biomass smoke is a serious public health problem, especially in rural areas of developing countries, because of its negative effects on pulmonary functions. As the duration and the intensity of exposure increase, the probability of having altered pulmonary function test results is higher
