Ultrasonic debridement

OBJECTIVE: The aim of this study was to evaluate the effectiveness of hand debridement (HD) versus ultrasonic dental scaler (UDS) for the treatment of experimental periodontitis (EP) in rats. MATERIAL AND METHODS: Thirty 3-month-old male rats were used. EP was induced around the mandibular first molars (right and left). Seven days after induction, the treatments with either HD (n = 30) or UDS (n = 30) were randomly performed in each molar. Euthanasia were performed at 7, 15, and 30 days after treatment...

Pulse lavage (PL) debridement is the standard treatment used in Debridement, Antibiotics and Implant Retention (DAIR) for bacterial biofilm removal during acute and early post-operative cases of periprosthetic joint infection (PJI). The failure rate of DAIR is still high due to the inadequacy of PL in removing the biofilm. Ultrasound-based techniques are a well-established tool for PJI diagnosis due to their ability to completely eradicate the biofilm from implant surfaces. Hence, this study investigates the efficiency of a piezoelectric ultrasonic scalpel (PUS) in removing bacterial biofilm from different orthopedic implant materials in vitro and compares the results with PL...

Chronic injury to the medial collateral ligament (MCL) is common following an acute knee injury. This case report presents two patients that failed to respond to conservative treatment with clinical evidence of an MCL injury and radiographic finding of a benign-appearing soft tissue lesion in the MCL. Calcified or ossified lesions have been described with chronic MCL injuries. Ossification and calcification of the MCL have been observed as potential causes of chronic MCL pain. Here, we detail the distinction between these two distinct intra-ligamentous heterotopic deposits and describe a novel treatment approach using ultrasonic percutaneous debridement, a technique that is typically reserved for tendinopathies...

The separation of an endodontic instrument during a root canal procedure is one of the most common endodontic mishaps. Separation of endodontic instruments may block access to the apical portion of the root and hamper the disinfection process. It obstructs the appropriate debridement of the canal apical to the fragment, jeopardizing the treatment's outcome. However, due to the advancements in the methods and armamentarium, the effective retrieval of a separated instrument (SI) from the root canal has become possible...

Aim Root canal obturation during endodontic therapy supports the root canal space and helps the extra tooth structure resist fracture. Some believe endodontic-treated teeth are more likely to break than natural teeth. The most common causes of tooth decay are endodontic treatment's extensive tooth structure loss and coronal and radicular dentin drying. Materials and methods Two hundred removed human permanent mandibular first molars were allowed to be stored in isotonic saline solution for a maximum of 72 hours...

Background and Objectives: Smear layer forms during cleaning and shaping can obstruct the entry of both irrigant and sealant into the dentinal tubules, resulting in the accumulation of the bacteria and their byproducts. To ensure effective adhesion and better periapical healing, it is strongly advised to remove the smear layer before proceeding with root canal obturation. This study was designed to compare the efficiency of laser-activated irrigation (LAI) in removing the smear layer and debriding the most apical third of the root canal...

The aim of this study was to evaluate the debridement efficacy of sonic irrigation (EDDY; VDW, Munich, Germany and EndoActivator; Dentsply-Sirona, Ballaigues, Switzerland) and ultrasonically activated irrigation (Irrısafe; Satelec Acteon, Merignac, France) in a simulated canal isthmus connecting curved canals. Transparent resin blocks were produced containing two curved canals connected with an isthmus. The isthmus was then filled with dentin debris. Three irrigant activation cycles were performed and the amount of remaining debris was compared analysing pictures taken after each activation cycle...

Ultrasonic debridement devices are minimally invasive and effective for biofilm removal, allowing for debridement of necrotic tissue while minimizing damage to normal tissues, such as the blood vessels and nerves. The use of ultrasonic debridement has been reported for foot ulcers and pressure ulcers but not Fournier gangrene. The perineal area, which is difficult to surgically debride using electrocautery, is a suitable site for the use of an ultrasonic debridement device because of its proximity to vital organs...

BACKGROUND: Ultrasonic scaling is a potential source of aerosol contamination in dental clinics. The two primary sources of microbial load in aerosols are from the oral cavity and dental unit water line. Literature evidence suggest that the use of preprocedural mouth rinse reduce the bacterial load in aerosol generated during ultrasonic scaling. AIM: The aim of the study is to assess the comparative efficacy of reduction in viable bacteria in the aerosol at patient's chest area, doctor's mask area and two feet beside the patient following use of chlorhexidine/herbal formulation diluted in the water source by a randomized controlled clinical trial...

OBJECTIVES: The aim of the present study was to evaluate the efficacy of a supportive peri-implant care (SPIC) protocol after surgical therapy of peri-implantitis, combining ultrasonic mechanical debridement and glycine powder air-polishing. MATERIAL AND METHODS: Thirty subjects diagnosed with peri-implantitis and treated by means of access flap were randomized six months later into two different SPIC groups: the test group combined a piezoelectric ultrasonic instrumentation with a specific implant PEEK tip and glycine powder air-polishing while control group received the same ultrasonic instrumentation together with a rubber cup and a polishing paste...

The treatment of pressure ulcer is of an extreme clinical and social concern. Effective and thorough debridement lays the foundation for favorable wound healing. Recently, a case report confirmed the efficacy of a combined application of methylene blue staining and ultrasonic debridement for pressure ulcer debridement. A 91-year-old male who suffered from severe pressure ulcers for over 6 years eventually obtained a favorable restoration after receiving surgical debridement optimized with methylene blue staining and ultrasonic debridement...

PURPOSE: Various methods have been proposed to achieve the nearly complete decontamination of the surface of implants affected by peri-implantitis. We investigated the in vitro debridement efficiency of multiple decontamination methods (Gracey curettes [GC], glycine air-polishing [G-Air], erythritol air-polishing [E-Air] and titanium brushes [TiB]) using a novel spectrophotometric ink-model in 3 different bone defect settings (30°, 60°, and 90°). METHODS: Forty-five dental implants were stained with indelible ink and mounted in resin models, which simulated standardised peri-implantitis defects with different bone defect angulations (30°, 60°, and 90°)...

The patient is a 65-year-old female recreational skier and avid walker who presented with a several-month history of right ankle and foot pain. The patient's pain began without inciting event and was described as a constant aching pain aggravated by downhill walking and alleviated with rest. She was diagnosed with right distal tibialis anterior tendinopathy with partial thickness tear noted on magnetic resonance imaging and musculoskeletal ultrasound. Given symptoms recalcitrant to conservative measures, the patient opted to pursue an ultrasound-guided prolotherapy injection and a course of physical therapy; unfortunately, she did not have any improvement in symptoms...

OBJECTIVE: This systematic review aims to assess the available literature on the clinical efficacy of hand versus power-driven instruments for subgingival instrumentation during surgical periodontal therapy (ST). MATERIALS AND METHODS: A search of the literature was carried out on MEDLINE via Ovid, Embase, Web of Science, the Cochrane Database, LILACS, and Scopus. RCTs comparing the use of powered instruments (test) to hand scalers (control) for subgingival instrumentation in terms of changes in probing pocket depth (PPD) after surgical periodontal treatment were included and screened in duplicate...

Peri-implant disease is usually caused by the accumulation of dental biofilm around the implant, and this biofilm can irradiate the gingiva tissue, which leads to inflammation and, more severely, to a deterioration of the bone structure. There is a concern regarding the removal of biofilm from the implant surface by using different hygiene instruments. Some hygiene instruments may have some effect on the dental implant surface, resulting in roughening or damage to the implant surfaces. This study reviewed the effects of titanium implant surfaces on different hygiene instruments...

BACKGROUND: Ultrasonic instrumentation (USI) has evolved, but it is unclear if dental hygiene curricula have kept pace. This study compares 2 dental hygiene cohorts with differing USI curricula to investigate if a contemporary USI curriculum enhanced students' USI preparation, use, and confidence. METHODS: A 2-group observational study compared a "traditional" USI curriculum (TC) cohort to a later "contemporary" USI curriculum cohort (CC). The new curriculum introduced USI earlier, with more and different inserts, and greater USI philosophical emphasis...
