This study aimed to compare the continuous rotation and reciprocating movements of rotary files in achieving apical patency in root canal retreatment.

This

, experimental study evaluated 64 extracted mandibular molars. The teeth were prepared up to F3 with ProTaper Universal and obturated using lateral compaction technique. The teeth were divided into four groups (

= 16) based on the mesiobuccal canal curvature (Schneider's method) and type of rotational movement. Groups 1 and 2 included straight canal teeth retreated with WaveOne Gold and ProTaper Universal Retreatment system, respectively. Groups 3 and 4 included teeth with moderately curved root canals retreated with WaveOne Gold and ProTaper Universal, respectively. Apical patency was ensured by observing the tip of a hand K-file at the apical foramen. Data were analyzed using the Fisher's exact test.

< 0.05 was considered statistically significant.

Apical patency was successfully achieved in all 16 teeth in group 1 (100%) and 15 teeth in group 2 (93.75%). No significant difference was noted between continuous rotation and reciprocating movements in straight canals (

= 1.00). Apical patency was successfully achieved in 15 teeth in group 3 (93.75%) and 12 teeth in group 4 (75%). No significant difference was noted between continuous rotation and reciprocating movements in moderately curved canals either (

= 0.333).

Both continuous rotation and reciprocating movements are equally effective in achieving apical patency in straight or moderately curved mesiobuccal canal of mandibular molars.

Dental scanners play a critical role in computer-aided design/computer-aided manufacturing technology. This study aimed to compare the accuracy (precision and trueness) of eight dental scanners for dental bridge scanning.

In this

experimental study, a typodont model with a missing maxillary right first molar was prepared for a 3-unit fixed partial denture. Each scanner (Sirona inEos inLab, Sirona X5, Dentium, Imes icore 350I I3D, Amann Girrbach map 100, 3Shape D100, 3Shape E3) performed seven scans of the typodont, and the data were analyzed using 3D-Tool software. The abutment length, abutment width, arch length, and interdental distance were measured. To assess the accuracy of each scanner, trueness was evaluated by superimposing the scanned data on true values obtained by the 3shape Triosscanner as the reference. Precision was evaluated by superimposing a pair of data sets obtained from the same scanner. Precision and trueness of the scanners were compared using the one-way ANOVA followed by the

Tukey's HSD test and one-sample

-test (P<0.05 was considerer significant).

The precision of scanners ranged from 14 μm (3Shape Trios) to 45 μm (Imes icore 350i), whereas the trueness ranged from 38 μm (3Shape d700) to 71 μm (Sirona X5).

The reported trueness values for 3Shape Trios, Sirona inEos inLab, Sirona x5, Dentium, Imes icore350i, Amann Girrbach, 3Shape d700, and 3Shape e3 were 63, 45, 71, 67, 70, 53, 38, and 42 μm, respectively, whereas the precision values were 14, 29, 44, 34, 45, 44, 30 and 28 μm, respectively.

The purpose of this study was conducted to evaluate the knowledge, attitude, and practice of intensive care unit (ICU) nurses about oral and dental care in hospitalized patients.

In this descriptive-analytic study, the statistical population included 214 nurses working in the ICU of the affiliated hospitals of Isfahan University in 1394. The level of knowledge, attitude, and practice of ICU nurses was assessed using questionnaires whose justifiability and stability were verified at the beginning of the study with a pilot study. Data were entered into SPSS software and tested by

-test, Spearman, one-way variance, and least significant difference test. The significance level was < 0.05.

The data of this study showed that the score of knowledge and performance in male nurses was significantly different from female nurses. There was a significant relationship between nurse's education and their knowledge score (

< 0.001). Furthermore, the performance score of nurses working in different parts was different too (

< 0.001).

The findings showed that the knowledge and performance of female nurses about oral care were higher than men, but the attitude of the two sexes is almost the same. Nurses with lower educational degree had less knowledge, but their attitude and performance did not differ. The performance score of nurses working in ICU was different, but they had similar knowledge and attitudes.

The tissue engineering has recently shown a significant progress in the fields of membranes and biosynthetic materials. Advanced platelet-rich fibrin (A-PRF) contains functional molecules that have newly shown great interest in regenerative therapies. The purpose of this study was to evaluate the effect of A-PRF on the adhesion of gingival fibroblast cells and osteosarcoma cells to different membranes.

In this experimental

study, three collagen, alloderm, and mucograft membranes were studied, which were cut into four 5 mm × 5 mm pieces and placed in the bottom of a 24-well culture medium. One milliliter of A-PRF was added to two wells from each group and the other two wells remained without A-PRF. The gingival fibroblasts and osteosarcoma cells were individually added to each well. The cell adhesion was studied using an electron microscope after 24 h. The data were analyzed by independent

-test, one-way analysis of variance, and least significant difference test.

In the presence of A-PRF, there wasch is similar to its absence. A-PRF was also found to be very effective on the adhesion of fibroblast cells to the collagen membrane, and in its absence, even less adhesion was observed compared to the other membranes. The presence or absence of A-PRF showed no significant differences in both cells' adhesion for alloderm and mucograft membranes.

There is no clinical study on ceramic self-ligating brackets (SLBs). Therefore, this preliminary study was conducted for the first time to address its effects.

This split-mouth randomized trial was performed on 32 quadrants in 16 orthodontic patients needing extraction of maxillary premolars and distalization of canines. In each blinded patient, right/left sides were randomized into control (ceramic bracket) and experimental (ceramic SLB) groups. Dental stone models were taken before canine retraction and 3 months into retraction. Models were digitized as three-dimensional models. Changes were measured on superimposed models. Groups were compared using Wilcoxon signed-rank test (α = 0.05, β = 0.1).

Both bracket types caused significant changes after 3 months in terms of all assessed clinical outcomes (

≤ 0.002). Compared to conventional ceramic brackets (control), ceramic SLBs reduced retraction rate (

= 0.001), canine rotation (

= 0.001), canine tipping (

= 0.002), and arch expansion at the can ceramic bracket after 3 months of treatment (considering the lower rate of SLB canine retraction during that time). Both brackets similarly constricted the arch at the premolar site. In the canine area, they expanded the arch, with the SLB causing smaller extents of expansion.Basaloid squamous cell carcinoma (BSCC) is an exceptional, aggressive variant of squamous cell carcinoma (SCC) because of its unique histological feature and an ominous clinical behavior. selleck kinase inhibitor Recently, it has been recognized as a high-grade SCC. The most preferential site of occurrence is the upper aerodigestive tract. Because of its aggressive behavior and tendency to metastasize, BSCCs are considered to have poor prognosis. We present a BSCC case in a 60-year-old male, which was clinically diagnosed as an aggressive inflammatory lesion with a differential diagnosis of granulomatous lesion, involving the mandibular anterior gingiva. Till now, only 17 cases of BSCC with gingival involvement have been reported in the literature. Here, we present one additional case of BSCC involving gingiva.

Adipocyte fatty acid binding protein (A-FABP) is a novel biomarker of inflammation for various chronic systemic diseases. Since periodontitis is a chronic inflammatory disease, this study explores the association of A-FABP with periodontal disease parameters and tumor necrosis factor-alpha (TNF-α) levels in gingival crevicular fluid in periodontal health and disease.

This original research article describes a cross-sectional study conducted at the Department of Periodontics, M. R. Ambedkar Dental College and Hospital, Bangalore, India. This cross-sectional investigation was conducted on sixty subjects which were divided into three groups of twenty subjects each - healthy, gingivitis, and chronic periodontitis. Clinical parameters - plaque index, bleeding index, probing depth, and clinical attachment loss were recorded. Gingival crevicular fluid samples were analyzed for A-FABP and TNF-α levels using ELISA. One-way analysis of variance was used to find the significance of study parameters on a continuous s a probable stimulatory effect on TNF-α; however, its role needs to be explored. A-FABP could serve as a novel inflammatory biomarker of periodontitis and the scope of using A-FABP inhibition as a treatment modality could be investigated with interventional studies.

A-FABP and TNF-α levels in GCF were significantly elevated in the presence of inflammation. A-FABP has a probable stimulatory effect on TNF-α; however, its role needs to be explored. A-FABP could serve as a novel inflammatory biomarker of periodontitis and the scope of using A-FABP inhibition as a treatment modality could be investigated with interventional studies.Mandibular tooth extractions for camouflage treatments in borderline Class III patients may end up with unpleasing esthetic results which may lead the patient seeking further complicated retreatments. In this case report, we presented a patient's retreatment with a combined orthodontic and orthognathic surgery treatment plan. The treatment strategy involved an innovative temporary anchorage device (TAD)-based method for total mandibular arch mesialization instead of space reopening for first lower premolar replacement with implants. In the current case report, orthognathic management of a Class III adult female is discussed. The patient had a history of an esthetically unsuccessful previous camouflaged orthodontic treatment with two lower premolar extractions. She was prepared for orthognathic surgery using an innovative custom-made sliding jig based on miniscrews for total mandibular arch mesialization with the aim of dental arch decompensation. After gaining the optimal dental arch discrepancy, the patient had orthognathic surgery (maxillary advancement and mandibular setback and advancement genioplasty).
