The interactions of dendritic cells with osteoblasts on titanium surfaces: an in vitro investigation.

Osteoimmune interactions possess a critical part in the integration of materials and hosts. Dendritic cells (DCs) are the most common members of osteoimmune cells family. The titanium surfaces of dental implants tend to promote a mature dendritic cell phenotype with increased proinflammatory secretion. However, very little is known to the effects of this microenvironment on the behaviors of cells around implants, especially osteoblasts, and how the tissue integrations take place on such biomaterial surfaces...

Osteotomy speed, heat development, and bone structure influence by various piezoelectric systems-an in vitro study.

The aim of this in vitro study was to evaluate osteotomy speed, heat development, and bone structure influence from osteotomies performed by various piezoelectric devices and insert tips. These devices and tips were compared among each other with regard to conventional rotatory and oscillating systems with special focus on the insert tip design and thickness.

Characterization of circulating DNA in plasma of patients after allogeneic bone grafting.

Cell-free DNA (cfDNA) harboring mutations has been found in patients with diseases. Experimental studies have shown that cfDNA can be transmitted, leading to transformations in the host. In the present study, we evaluated whether bone allograft material contains cfDNA and whether this foreign cfDNA can be released into the patient's blood circulation.

Antibiotic prophylaxis may not be indicated for prevention of dental implant infections in healthy patients. A systematic review and meta-analysis.

The purpose of the present systematic review and meta-analysis is to determine the efficacy of antibiotic prophylaxis and specific antibiotic regimens in dental implant placement for prevention of post-operative infection (POI) in overall healthy patients.

Risk factors associated with long-term outcomes after active and supporting periodontal treatments: impact of various compliance definitions on tooth loss.

The aim of this retrospective study was to determine factors influencing tooth loss during a long-term follow-up, emphasizing the impact of various compliance definitions.

Accuracy of crowns based on digital intraoral scanning compared to conventional impression-a split-mouth randomised clinical study.

The aim of this prospective in vivo study was to evaluate the accuracy of the marginal and internal fit of crowns based on conventional impression (CI) or intraoral scan (IOS) in a randomised, split-mouth set-up.

Prospective clinical study of bilateral balanced occlusion (BBO) versus canine-guided occlusion (CGO) in complete denture wearers.

Previous studies have often discussed occlusal concepts for complete dentures without formulating a recommendation. Various options are available, the most common ones being canine-guided occlusion (CGO) and bilateral balanced occlusion (BBO). We designed a prospective randomized study to compare these two schemes with the goal of formulating a recommendation.

Do dental bleaching agents induce genetic damage on oral mucosa cells?

Detection and measurements of apical lesions in the upper jaw by cone beam computed tomography and panoramic radiography as a function of cortical bone thickness.

In the current literature, cone beam computed tomography (CBCT) seems to be more accurate in detecting apical lesions (AL) than two-dimensional radiographs. Cortical bone thickness might have an influence on AL visibility. Therefore, the purpose of the study was to directly compare the diagnostic accuracy of panoramic radiography (PANO) and CBCT in detecting AL in the upper jaw and determine the influence of cortical bone thickness on AL visibility.

Do electrical current and laser therapies improve bone remodeling during an orthodontic treatment with corticotomy?

Evaluate the bone remodeling during orthodontic movement with corticotomy when submitted to low-intensity electrical stimulation application (microcurrent-MC) and low-level laser therapy (LLLT).

Relationship between periodontal inflammation and calcium channel blockers induced gingival overgrowth-a cross-sectional study in a Japanese population.

Periodontal inflammation is regarded as a risk factor for drug-induced gingival overgrowth (DIGO). In order to elucidate the involvement of periodontal inflammation in DIGO, the periodontal status of subjects who do not develop DIGO despite receiving causative drugs (non-responders) needs to be examined. Therefore, the aim of the present study which was a pilot study was to assess periodontal inflammatory variables in responders (calcium channel blocker induced-GO patients), non-responders, and patients who...

Effectiveness of the ozone application in two-visit indirect pulp therapy of permanent molars with deep carious lesion: a randomized clinical trial.

The aim of this randomized, three-arm parallel, single-blinded clinical trial was to evaluate the clinical and microbiological effectiveness of the ozone application in two-visit indirect pulp therapy.

Visibility, location, and morphology of the primary maxillary sinus ostium and presence of accessory ostia: a retrospective analysis using cone beam computed tomography (CBCT).

This retrospective study evaluated the visibility, location, and morphology of the primary maxillary ostium (PMO), as well as the presence and number of accessory maxillary ostia (AMO) in the maxillary sinus using cone beam computed tomography (CBCT).

Polymerization pattern characterization within a resin-based composite cured using different curing units at two distances.

To investigate the relationship of the irradiance-beam-profile areas from six different light-curing units (LCUs) with the degree of conversion (DC), microhardness (KH), and cross-link density (CLD) throughout a resin-based composite (RBC) cured at two clinically relevant distances, and to explore the correlations among them.

Relationship between the anatomic structures and mandibular posterior teeth for endodontic surgery in a Turkish population: a cone-beam computed tomographic analysis.

The purpose of this study is to evaluate the relationship between anatomic structures and mandibular posterior region using cone-beam computed tomography (CBCT) in terms of endodontic surgery.

Impact of type of tooth on outcome of non-surgical root canal treatment.

We assessed the impact of type of tooth on the outcome of root canal treatment (RCT) according to factors potentially weakening the prognosis such as preoperative apical periodontitis (AP) and treatment modality (primary or secondary RCT).

Nuclear morphological changes in gingival epithelial cells of patients with periodontitis.

This study assessed the frequency of nuclear morphological changes in gingival epithelial cells, as a biomarker for DNA damage, in individuals with periodontitis, before and after implementation of periodontal therapy, and compared the morphology to those with healthy periodontal tissues.

Experimental mucositis/gingivitis in persons aged 70 or over: microbiological findings and prediction of clinical outcome.

To assess in persons aged 70 years or older the microbiological alterations occurring around implants and natural teeth during and after 3 weeks of undisturbed plaque accumulation. Furthermore, to test the predictive value of several markers at baseline for the extent of inflammation around implants and teeth after this period.

The aim of this study was to analyze the biological effects of MTA Repair HP and ProRoot MTA on human periodontal ligament stem cells (hPDLSCs) after exposure to acidic and neutral environments.

A novel histopathological scoring system for patients with oral squamous cell carcinoma.

Tumor invasion into blood and/or lymphatic vessels, perineural invasion, and histopathological grading are evaluated to assess the biological aggressiveness of oral squamous cell carcinoma (OSCC). We aim to assess the prognostic impact of a novel scoring system, based upon the aforementioned histological parameters.

N-acetyl cysteine versus chlorhexidine mouthwashes in prevention and treatment of experimental gingivitis: a randomized, triple-blind, placebo-controlled clinical trial.

To compare the efficacy of N-acetyl cysteine (NAC) mouthwash with chlorhexidine (CHX) in prevention and treatment of experimental gingivitis MATERIALS AND METHODS: Sixty subjects were assigned randomly and blindly into one of three equal groups: NAC, CHX, or placebo group. The study was conducted in two stages: preventive and treatment substudies. Professional prophylaxis was performed ahead of starting the preventive substudy. Then, the subjects were instructed to stop oral hygiene practices and begin rins...

Following in the footsteps of Hippocrates-interrelation between the incidence of odontogenic abscess and meteorological parameters.
