Public Compliance with Face Mask Use in Honolulu and Regional Variation.

Infections with the SARS-CoV-2 virus are increasing in Hawai'i at alarming rates. In the absence of a SARS-CoV-2 virus vaccine, the options for control include social distancing, improved hygiene, and face mask use. There is evidence that mask use may decrease the rates of viral transmission.

Sinus Augmentation with Simultaneous, Non-Submerged, Implant Placement Using a Minimally Invasive Hydraulic Technique.

To evaluate whether sinus augmentation, using a minimally invasive implant device, via a non-submerged surgical approach, might negatively influence the outcome. A retrospective cohort study was conducted by evaluating patients' files, classifying them into two groups. Fifty patients (22 men 28 women) were included in the study, 25 in each group.

The Feasibility of Flapless Approach to Sinus Augmentation Using an Implant Device Designed According to Residual Alveolar Ridge Height.

Hydraulic sinus lift and augmentation may be successfully performed using a dedicated implant device designed according to residual bone height (RBH). The aim of this study was to evaluate whether a flapless surgical approach might negatively influence the outcome. A total of 40 consecutive patients (16 men and 24 women) were included in the study, 20 in each group (minimal flap/control versus flapless/study).

Purpose: To evaluate clinical and radiographic performance of a novel implant system that allows for hydraulic Schneiderian membrane elevation and simultaneously bone graft augmentation.

Materials And Methods: Sixty-two consecutive patients with a mean age of 53.1 years and a severe atrophy of the posterior maxilla (3.

Patients perceptions of recovery after maxillary sinus augmentation with a minimally invasive implant device.

Objective: Patients' perceptions of recovery following sinus augmentation procedures have scarcely been documented. The aim of the present prospective pilot clinical study was to evaluate the patient's perception of immediate postoperative recovery after sinus augmentation, using a minimally invasive implant device.

Method And Materials: Eighteen patients (8 men, 10 women), average age 52 (median 48, range 38 to 72), who had been scheduled for sinus augmentation procedures, were asked to enroll in a prospective clinical study.

Minimally invasive sinus lift implant device: a multicenter safety and efficacy trial preliminary results.

Purpose: In cases of advanced maxillary sinus atrophy of the bone (pneumatization), the sinus floor has to be augmented in order to obtain acceptable bone volume for implantation. The objective of the present study is to evaluate a new procedure and device, designed as a closed sinus lift using a dedicated dental implant that allows for Schneiderian membrane elevation and the placement of a flowable bone replacement graft.

Materials And Methods: Eighteen patients (8 males, 10 females) underwent 23 procedures.

Healing kinetics of periapical lesions enhanced by the apexum procedure: a clinical trial.

The new Apexum procedure (Apexum Ltd, Or-Yehuda, Israel) is based on a minimally invasive removal of periapical chronically inflamed tissues through a root canal access. Its goal is to enhance healing kinetics of periapical lesions. This clinical study was conducted to explore the safety and efficacy of this procedure.

Enhancement of healing kinetics of periapical lesions in dogs by the Apexum procedure.

In nonsurgical endodontic procedures, the healing of apical periodontitis is achieved by treatment provided within the root canal system. The new Apexum procedure is based on advancing the debridement one step further by minimally invasive removal of the inflamed periapical tissues through root canal access, thereby enhancing the healing kinetics of periapical lesions. The Apexum procedure uses 2 sequential rotary devices designed to extend beyond the apex and to mince periapical tissues on rotation in a low-speed handpiece, followed by washing out the minced tissue.

Immediate root canal disinfection with ultraviolet light: an ex vivo feasibility study.

Objective: The study was designed to test application of ultraviolet light to root canal walls, as a mean of complementary immediate disinfection after the use of sodium hypochlorite.

Study Design: Root canals were infected ex vivo with Enterococcus faecalis for 48 hours. Non-attached bacteria were washed away, and the remaining attached bacteria were subjected to disinfection, with 5% sodium hypochlorite alone or followed by exposure to ultraviolet light (254 nm, 300 mJ/cm(2)).

Sensitivity of oral bacteria to 254 nm ultraviolet light.

Aim: To explore the sensitivity of bacteria commonly found in root canals to 254 nm ultraviolet (UV) light, either as individual cells or as participants of a bacterial multilayer.

Methodology: The sensitivity of oral bacteria, as individual cells, to UV light was tested by subjecting plates streaked with bacteria to 254 nm UV, at a fluence of 1-20 mJ cm(-2). An experimental model was designed to produce a bacterial multilayer and to study absorption of UV light by bacteria in an outer layer and its effect on the elimination of bacteria in the inner layer.

[Avascular necrosis of the jaw bone after bisphosphonate therapy].

Bisphosphonates have an antiosteolytic effect by the inhibition of osteoclastic action. Although the exact mode of action is not completely understood, major progress on both the cellular and molecular levels has been made in recent years. Bisphosphonates alleviate pain and reduce complications, such as pathologic fractures, or hypercalcemia.

The clinical effectiveness of 6 mm diameter implants.

Background: Five- and 6 mm diameter screw-type endosseous implants have been used for the last decade. While some studies have reported very promising results (94% to 98% success rate), others have demonstrated survival rates below those clinically acceptable (75% to 87%). Moreover, such implants have been associated with increased cervical bone resorption and thread exposure.

The presurgical workup before third molar surgery: how much is enough?

Purpose: We sought to assess the indications for patient referral for computed tomography (CT) scan before third molar extraction. The influence of the data obtained from the CT scans on the surgical outcome and morbidity was also evaluated.

Patients And Methods: There were 189 patients in the study (120 females and 69 males).

[The use of autogenous block graft for augmentation of the atrophic alveolar ridge].

The use of osseointegrated implants has become a standard treatment option in modern dental rehabilitation. Adequate bone quantity and quality is a prerequisite for good esthetic and biomechanical result. Alveolar ridge defects can be the result of trauma, periodontal diseases or other pathologic conditions.

Case selection for apical surgery: a retrospective evaluation of associated factors and rational.

Endodontic failures associated with poor quality of endodontics respond favorably to retreatment. Nevertheless, under certain clinical conditions, apicoectomy should be the preferred procedure. A retrospective survey of 200 roots that were referred for apical surgery revealed that 83% of the roots were inadequately obturated, including 8.

Electron microscope and biochemical observations of the surface active phospholipids on the articular surfaces and in the synovial fluid of the temporomandibular joint: a preliminary investigation.

Purpose: The goal of this article is to investigate the surface-active phospholipids located on the articular surfaces and in the temporomandibular joint (TMJ) synovial fluid (SF) by means of electron microscopy and biochemical analysis.

Materials And Methods: Synovial fluids and articular cartilage samples taken from 6 normally functioning TMJs were studied. The osmiophilic lining of human TMJ articular surfaces has been studied by using special nondestructive fixation procedures.

Long-term outcome of arthrocentesis for sudden-onset, persistent, severe closed lock of the temporomandibular joint.

Purpose: This study analyzed the long-term effect of arthrocentesis for severe closed lock of the temporomandibular joint (TMJ) and reevaluated the pathogenesis of this condition based on the data obtained.

Patients And Methods: Thirty-nine patients (40 joints) who had experienced sudden-onset, persistent limited mouth opening were the subjects of this study. After unsuccessful noninvasive treatment, arthrocentesis of the upper compartment of the affected TMJ was performed using saline.
