BACKGROUND: Previous studies have provided substantial evidence on the association of Aggregatibacter actinomycetemcomitans (Aa), and its highly leukotoxic JP2 genotype, with localized aggressive periodontitis (LAP). The present study aims to evaluate the presence of JP2 in LAP individuals following periodontal treatment. METHODS: Sixty African American LAP patients between ages 5 and 25 years were examined. At baseline, pocket depth (PD), clinical attachment level (CAL), bleeding on probing (BoP) and plaque index were measured and subgingival plaque was collected from both LAP diseased sites and healthy sites for each participant...

The dreaded fracture of a root canal instrument is in fact a rare adverse event. Most instrument fractures occur in molar teeth with the highest degree of root curvature. Various treatment options (leaving the fractured instrument with or without apicoectomy, bypassing or removing the fragment) and removing techniques (using ultrasonics, hollow tubes or bypassing and removing with debriders) are discussed. The clinical prognosis for teeth with fractured instruments is not necessarily compromised if appropriate further treatment is undertaken...

OBJECTIVE: The aim of this study was to compare the effectiveness of five intracanal agitation techniques on the penetration of irrigant and sealer into dentinal tubules. BACKGROUND DATA: Intracanal agitation techniques could promote chemomechanical debridement and the sealing of root canals during endodontic treatment. However, there is limited evidence for the agitation effect of Nd:YAP laser. MATERIALS AND METHODS: Human maxillary premolars with single straight canals (N = 60) were prepared with ProTaper Next(®) NiTi rotary files (Dentsply Maillefer) up to X4 (ISO 40 size)...

PURPOSE: There is no consensus on how to successfully treat medication-related osteonecrosis of the jaws (MRONJ). We report here on the application of piezoelectric bone surgery to treat MRONJ in combination with antibiotherapy and on its possible benefit. MATERIEL AND METHODS: A cohort of 18 consecutive patients has been treated for MRONJ; they involved 20 sites, 15 in the mandible, and five in the maxilla. Surgical removal of the necrotic areas and debridement was performed with a powerful piezoelectric surgery device (max 90 W) in combination with antibiotherapy...

OBJECTIVES: The ultrasonic NO PAIN technology (Electro Medical Systems, Nyon, CH) promises minimal pain during debridement due to linear oscillating action combined with a sinusoidal power output and feedback control. The aim of the present study was to measure pain perception on a visual analogue scale (VAS) during supportive periodontal therapy including debridement of hypersensitive teeth. Two ultrasonic scalers were used, one with and one without NO PAIN technology. MATERIAL AND METHODS: In a randomized-controlled clinical study with split-mouth design, 100 hypersensitive teeth matched for air blast hypersensitivity were either treated with the ultrasonic device Piezon Master 700 or the Mini Piezon (both EMS, Nyon, CH)...

The aim of the present study was to investigate the clinical outcomes of two different standardized endodontic irrigation protocols. It was assumed that the additional use of ethylenediaminetetraacetate (EDTA) and passive ultrasonic irrigation (PUI) would result in an increased rate of absence of symptoms and remission based on the periapical index (PAI) compared to passive irrigation using only sodium hypochlorite (NaOCl). Data and radiographs from 199 teeth retrieved from the institutional endodontic database were analyzed retrospectively...

Periodontal disease is characterized by chronic inflammation in subgingival areas, where a vast array of inflammation-associated metabolites are likely produced from tissue breakdown, increased vascular permeability, and microbial metabolism and then eventually show a steady flow into saliva. Thus, prolonged periodontal inflammation is a key feature of disease activity. Although salivary metabolomics has drawn attention for its potential use in diagnosis of periodontal disease, few authors have used that to investigate periodontal inflammation detection...

Diabetes has become a global epidemic. Its complications can have a significant impact on quality of life, longevity, and public health costs. The presence of diabetes might impair the prognosis of periodontal treatments due to its negative influence on wound healing. Antimicrobial photodynamic therapy (aPDT) is a local approach that can promote bacterial decontamination in periodontal pockets. The aim of this study was to investigate the local effect of adjunct aPDT to ultrasonic periodontal debridement (UPD) and compare it to UD only for the treatment of chronic periodontitis in type 2 diabetic patients...

BACKGROUND: Low-frequency ultrasonic debridement (LFUD) is a technology that uses sound waves conducted through saline mist to debride wound tissue. Whilst this technology purportedly reduces wound-healing times, the airborne mist generated is potentially problematic. Theoretically, the saline mist could carry an increased number of microbes into the surrounding environment, posing an infection control risk to the patient, clinician, and clinical environment. This research aimed to establish the degree and extent to which there is microbial spread during the use of, and following the use of, LFUD...

Introduction. Surgical management of infrabony defects is an invasive procedure, frequently requiring the use of adjunctive material such as grafts or biologics, which is time-consuming and associated with expense and morbidity to the patient. Lasers in periodontal regeneration have been reported in the literature, with each wavelength having potential benefits through different laser-tissue interactions. The purpose of this case series was to assess the efficacy of a new dual-wavelength protocol in the management of infrabony defects...

BACKGROUND: Despite the development of less invasive devices, a debate exists about the benefits and risks of hand versus powered root surface instrumentation used in supportive periodontal therapy (SPT). The aim of the in vitro study was to differentially compare plaque removal efficacy and root surface roughening of newly developed sonic, ultrasonic scaler, and curettes in the hands of experienced versus less experienced operators. MATERIALS AND METHODS: Sonic (AIR), ultrasonic devices (TIG), and double-gracey curettes (GRA) were utilized by seven experienced (EO) and four less experienced operators (LO) for root surface instrumentation of standardized plastic teeth on manikins' heads in a randomized sequence...

This case report discusses the identification and management of complex canal configuration of 3-2-1 in the mesiobuccal (MB) root of the maxillary left first molar. Careful attention to details of the pulpal floor and applying the knowledge of the laws of orifice location along with deepening the subpulpal groove with ultrasonic tips helped in identifying the three MB canals. Manual scouting helped in understanding the anatomic configuration; the use of three-dimensional imaging technique and spiral computed tomography (SCT) confirmed the same...
