Genel anestezi altinda treacher collins sendromlu bir hastanin diş tedavisi: Vaka raporu

This article reports a case of Treacher Collins syndrome (TCS) in a five-year-old male patient treated in Kirikkale University, Department of Pediatric Dentistry. We defined the clinic signs and symptoms of the case and suggested a treatment plan. Treatment procedures for malformations caused by the syndrome should be planned and performed specifically for the patient. In our patient with low treatment compliance, dental examination, filling and partial prosthesis treatment was successfully applied under general anesthesia. © 2019 Cumhuriyet University Faculty of Dentistry.Bu vakada Kirikkale üniversitesi çocuk Diş Hekimliği Bölümü'nde tedavi edilen Treacher Collins Sendromlu 5 yaşindaki erkek hasta sunulmaktadir.

Evaluation of push-out bond strength of a new MTA-based sealer

PubMed: 23645545Aim: To evaluate the push-out bond strength of MTA Fillapex (Angelus) and compare it with ProRoot MTA (Dentsply) and AH Plus (Dentsply). Design: Thirty extracted single-rooted teeth were selected and prepared using a rotary system. The samples were divided randomly into three groups (n = 10) and obturated, respectively, with: (1) AH Plus + gutta-percha (DiaDent); (2) MTA Fillapex + gutta-percha; (3) ProRoot MTA. Each root was sectioned into 1-mm-thick slices and 30 samples for each group were obtained. The samples were subjected to push-out test. Failure modes were examined under 30× magnification. The results were analysed statistically by one-way ANOVA and Tukey's test. Results: Mean push-out bond strength values were ranked as follows: ProRoot MTA > AH Plus > MTA Fillapex. Statistically significant differences were found among all groups (p < 0.05). Conclusion: ProRoot MTA had the highest bond strength, whilst MTA Fillapex displayed the lowest values among the groups. © 2013 European Academy of Paediatric Dentistry

Efficacy of licorice lollipops in reducing dental caries in a paediatric population: A systematic review

PubMed: 32238980Purpose: To assess the efficacy of licorice lollipops in reducing dental caries in children. Materials and Methods: A literature search was confined to the English language using MeSH terms congruent with PICO format in 'PubMed', 'Cochrane Library' and 'Ovid', covering the period from April 1967 to December 2017. Searches in Google Scholar, grey literature and hand search of cross-references were performed to find additional data. Suitable studies were selected based on the predefined inclusion and exclusion criteria. Quality analysis and risk of bias of the selected studies were performed using the Cochrane Collaboration's tool for risk of bias. Results: Overall 519 articles were retrieved, 516 (electronic databases) and 3 (Google scholar). 516 publications were excluded due to non-availability of abstracts, or because they were unrelated studies, narrative reviews, and systematic reviews as well as letters to editors. Only three studies were included for final analysis. Quality analysis of these three studies showed that only one was of high quality, whereas the other two were rated as low. Conclusion: Licorice lollipops showed a promising effect in reducing caries by decreasing Streptococcus mutans counts in the saliva. Further research using randomised controlled clinical trial (RCT) designs with large sample size are recommended. © 2020, Quintessence Publishing Co., Ltd.Majmaah University: R-1441-44The authors would like to thank the Principal, Narayana Dental College and Hospital, Nellore, Andhra Pradesh, P, India for support, as well as the Deanship of Scientific Research at Majmaah University for supporting this work under project No. R-1441-44

In vitro evaluation of apical microleakage of a new MTA-based sealer

PubMed: 23043882Aim: To evaluate the apical microleakage of a new MTA-based sealer; MTA Fillapex (Angelus) and compare it with ProRoot MTA (Dentsply) and AH Plus (Dentsply). METHODS: 51 single-rooted permanent teeth were selected and the roots were prepared using a rotary system. The samples were divided randomly into 3 groups (n=15). Six roots were used as positive and negative controls. The teeth were obturated with respectively; A. AH Plus and gutta percha (DiaDent); B. MTA Fillapex and gutta percha; C. ProRoot MTA. Specimens were placed in 2% methylene blue dye for 72h. Then linear dye penetration was measured. Measurements were analysed statistically. RESULTS: MTA Fillapex group had significantly higher microleakage values (p0.05). CONCLUSION: The sealing ability of AH Plus and MTA were similar whilst MTA Fillapex showed more microleakage than the other two materials

Purification of peroxidase enzyme from radish species in fast and high yield with affinity chromatography technique

PubMed ID: 30939412In this study, an effective single step affinity method is presented for purifying plant peroxidase (POD) enzymes from radish species. This method make possible to purify the enzymes in high yield and purity. Briefly, 10 different 4-amino benzohydrazide derivatives were synthesized and identified as new competitive POD inhibitors. Then, these derivatives were coupled to Sepharose 4B-L-Tyrosine support matrix by diazotization to form the affinity gels. Purification factors were recorded as 54.8% yield - 665-fold, 33.8% yield - 613-fold, 22.7% yield - 595-fold, 34.4% yield - 781-fold, 40.9% yield - 282-fold for turnip (T-POD), black radish (BR-POD), daikon (D-POD), sweet radish (SR-POD) and kohlrabi radish, (KR-POD), respectively. It has also been shown that the affinity gels, which prepared using the 4-amino 3-bromo benzohydrazide and 4-amino 2-nitro benzohydrazide molecules, capable to purify all radish species POD enzymes in high purity and yield. © 2019 Elsevier B.V.215Z386This study was supported by TUBITAK with 215Z386 project number
