ABSTRACT Using a method which permits bile collection relatively free from stress or trauma, we have studied flow in normal and hypophysectomized rats. Hypophysectomy was found to result sharply reduced not increased by small doses of corticosterone deoxycorticosterone. Adrenalectomy, previously reported similar effect, reduce either the two strains rats studied.

The purpose of this study was to evaluate the effect photodynamic therapy (PDT) using erythrosine and a green light emitting diode (LED) source on biofilms Aggregatibacter actinomycetemcomitans attached resorbable blasted media (RBM) sandblasted, large-grit, acid-etched (SLA) titanium surfaces in vitro. RBM SLA disks were subdivided into four groups, including one control group three test groups (referred as E0, E30, E60), order PDT each surface. E0 put 500 µL 20 µM for 60 seconds without...

Abstract Objective: To evaluate changes that occur in the subgingival microbiota after removal of fixed orthodontic appliances using polymerase chain reaction (PCR). Materials and Methods: Thirty patients (11 males 19 females; aged 20 ± 7.3 yr) were included this study. Subgingival plaque samplings gathered from disto-buccal gingival crevice left upper central incisors lower incisors, mesio-buccal first molars molars, at two different times: 2 weeks before appliance (T1), 3 months (T2). DNA...

This study aimed to compare the long-term survival rate and peri-implant marginal bone loss between different types of dental implant-abutment connections.Implants with external or internal abutment connections, which were fitted at Gangneung-Wonju National University Dental Hospital from November 2011 December 2015 followed up for >5 years, retrospectively investigated. Cumulative rates evaluated was 1- 5-year follow-up examinations after functional loading.The 8-year cumulative 93.3% 90.7%...

The purpose of this study was to compare the characteristics single- and dual-species in vitro oral biofilms made by static dynamic methods. Hydroxyapatite (HA) disks, 12.7 mm diameter 3 thick, were coated with processed saliva for 4 hours. disks divided into a method group group. treated cultured 12-well plates, Center Disease Control Prevention (CDC) biofilm reactor 72 In biofilms, Fusobacterium nucleatum Porphyromonas gingivalis used, amount adhering bacteria, proportions species,...

The purpose of this retrospective study was to evaluate the effect patient compliance with supportive periodontal therapy (SPT) on tooth loss in Korean adults. records 134 patients were reviewed for study. They completed active treatment from 1999 2001 and placed a schedule periodic follow-up visits SPT. Patient classified into complete (CC), erratic (EC), noncompliance (NC) groups. Re-examinations carried out 11.0±0.8 years after treatment. prognosis each determined as good, questionable,...

The objective of this study was to analyze orthotropic bone formation and remodeling three different dental implant surfaces with without recombinant human morphogenetic protein 2 derived from Escherichia coli (ErhBMP-2) in a rabbit model.Resorbable blasting media (RBM); sandblasted, large-grit, acid-etched (SLA); magnesium-incorporated oxidized (MgO) were coated ErhBMP-2 (1.5 mg/mL). implants placed into the proximal tibia six New Zealand White rabbits. Each received (three one uncoated...

The purpose of this study was to determine the critical diabetes duration in a streptozotocin (STZ)-induced diabetic rat calvarial defect model for experimentation regarding bone regeneration by evaluating association between and healing capacity through histological radiographic analyses.Experimental induced 50 60 rats an STZ injection. were divided into 5 groups, including control group (group 1), according durations 0, 2, 4, 6, 8 weeks, respectively. Eighteen survived: 4 1, 3, 1 5....

Purpose: Osteotome sinus floor elevation (OSFE) is an often-used technique of great utility in certain implant patients with resorbed posterior maxilla.Recently benign paroxysmal positional vertigo (BPPV) has been reported as early postoperative complication following OSFE.Although OSFE-induced BPPV commonly resolves itself within a month without treatment, this can be cause trouble between the surgeon and patient.This report presents case OSFE.Methods: A 27-year-old man any significant...

The purpose of this study was to radiographically evaluate marginal bony changes in relation different vertical positions dental implants. Two hundred implants placed 107 patients were examined. classified by the fixture-abutment connection (microgap): 'bone level,' 'above bone or 'below level.' Marginal levels examined radiographs taken immediately after fixture insertion, second-stage surgery, 6 months prosthesis and 1 year insertion. Radiographic evaluation carried out measuring distance...

The aim of this study was to obtain objective and standardized information on masticatory function patient satisfaction following second molar single implant therapy. Twenty adult patients, who had restored implants more than 1 month before the study, were enrolled in study. All patients received a chewing test using peanuts after insertion prosthesis, with questionnaire visual analogue scale (VAS) evaluate effect This obtained objectively (e.g., P, R, X(50)) (Pre-insertion) (Post-insertion)...

Purpose This study aimed to evaluate the clinical and microbiological efficacy of adjunctive local delivery minocycline (Periocline®) in patients receiving supportive periodontal therapy (SPT) after initial treatment. Methods The participants were 16 men 8 women (age, 20-65 years) who had at least 15 natural teeth, underwent SPT for more than 1 year due chronic periodontitis, 4 or pocket sites deeper 5 mm, showed >25% gingival bleeding on probing (BoP). They randomly assigned test control...

The aim of this study was to evaluate the antimicrobial effect a newly devised toothbrush with light-emitting diodes (LEDs) on Porphyromonas gingivalis attached sandblasted and acid-etched titanium surfaces.The included control group, commercial photodynamic therapy (PDT) 3 test groups (B, BL, BLE). disks in PDT group were placed methylene blue then irradiated diode laser. B only brushed, BL brushed an LED toothbrush, BLE into erythrosine toothbrush. After different treatments, bacteria...

This study aimed to characterize the early stages of periodontal disease and determine optimal period for its evaluation in a mouse model. The association between duration ligation effect on dentogingival area mice was evaluated using micro-computed tomography (CT) histological analysis.Ninety were allocated an untreated control group or which periodontitis induced by 6-0 silk around left second maxillary molar.
