AIM: The aim of the study was to assess the prevalence of apical periodontitis (AP) and quality of root canal fillings in an adult Moroccan subpopulation. METHODS: In the study 508 patients were included, attending the Conservative Dentistry Clinic at the Faculty of Dentistry of Casablanca. 508 panoramic and 709 periapical radiographs were observed. The periapical status of all teeth (with the exception of third molars) was examined according to Ørstavik's periapical index...

INTRODUCTION: The present study aimed to evaluate the prevalence of apical periodontitis (AP) and endodontic treatment in patients with end-stage renal disease (ESRD) as compared with patients with no history of ESRD. METHODS: In this cross-sectional study, 40 patients diagnosed with nondiabetic ESRD were included. The control group consisted of 40 age-matched and sex-matched healthy individuals. Digital panoramic radiographs were exposed on patients in both the experimental and control groups...

BACKGROUD/PURPOSE: Aggregatibacter actinomycetemcomitans has emerged as one of the aetiological agents in periodontal disease. Although Type IV secretion systems (T4SSs) are widely distributed in many bacteria, the genetic features and distribution of T4SSs in A. actinomycetemcomitans remain unclear. In this study, we investigated the prevalence of A. actinomycetemcomitans serotypes and their T4SSs in a Taiwanese population. METHODS: A comparative analysis of 20 A...

INTRODUCTION: Oral health education/promotion interventions have been identified as cost-efficient tools to improve the oral health of the population. These interventions are regularly made in contexts where the target population is captive, for example, in health centres. In Chile, there are no oral health interventions delivered at home. METHODS AND ANALYSIS: This community trial covers two disadvantaged urban areas in the province of Concepción. Both sectors have public preschool education coverage with a traditional programme (TP) to promote oral health...

BACKGROUND: Peripheral dental caries is defined as macroscopic destruction of the calcified dental tissues and can be a cause of considerable dental pathology and pain. It appears to have a high prevalence within Western Australian horses and, at present, risk factors for the condition are poorly understood, making treatment and prevention difficult. OBJECTIVES: To assess the prevalence and potential risk factors involved in peripheral caries in horses in Western Australia...

AIM: We explored the association between obesity and periodontitis with the aim of determining the possible role of insulin resistance (IR) in this relationship. MATERIALS AND METHODS: A total of 212 subjects -110 obese and 102 lean individuals- were evaluated for periodontal disease and divided according to IR: a lean group without IR (LWIR); an obese group without IR (OWIR); and an obese group with IR (OIR). Anthropometric, metabolic, inflammatory and periodontal parameters were evaluated...

BACKGROUND: Periodontal disease associates with systemic diseases but corresponding links regarding apical periodontitis (AP) are not so clear. Hence our aim was to study association between AP and the prevalence of systemic diseases in a study population from Sweden. METHODS: The subjects were 150 patients from a randomly selected epidemiological sample of 1676 individuals. 120 accepted to participate and their basic and clinical examination data were available for these secondary analyses where dental radiographs were used to record signs for endodontic treatments and AP...

Periodontitis is a prevalent and chronic inflammatory disease that is interrelated with systemic health. Periodontitis can be promoted by tumor necrosis factor α (TNF-α). Cementum, a vital part of the periodontium, is a bone-like mineralized tissue that is produced by cementoblasts. Our laboratory previously revealed that TNF-α inhibits cementoblast differentiation and mineralization. However, how TNF-α modulates cementoblast differentiation and mineralization remains largely unknown. MicroRNA-155 (miR-155) is induced and regulates TNF-α-inhibited osteogenic differentiation...

Alzheimer’s disease (AD) is a very common cause of dementia in developed countries and increases its prevalence progressively with age. AD etiopathogenesis is not yet understood. However, it is recognized that neuroinflammation plays a key role in its pathogenesis with the activation of microglia and the secretion of proinflammatory cytokines triggering irreversible neurodegenerative deterioration. This paper is a short review of the relationship between AD and periodontal disease (PD). Both processes may have common causes: both are inflammatory diseases and the prevalence and progression increases with ageing...

Objective: The aim of this study was to investigate the prevalence of isolated Candida albicans from periodontal endodontic lesions in diabetic and normoglycemic patients, and the fungi's virulence in different atmospheric conditions. Material and Methods: A case-control study was conducted on 15 patients with type 2 diabetes mellitus (G1) and 15 non-diabetics (G2) with periodontal endodontic lesions. Samples of root canals and periodontal pockets were plated on CHROMagar for later identification by polymerase chain reaction (PCR) and virulence test...

REVIEW
Lourdes Román-Malo, Pedro Bullon
Periodontal disease is considered one of the main pathologic diseases occurring in humans. Its pathologic process involves inflammatory reactions producing periodontal bone resorption and the tooth loss. But some patients do not present an evident clinical inflammation with bone resorption, and in others, the inflammation is prominent without bone resorption. A key question could be to investigate a different way of responding to aggression. Inflammation requires a complex intracellular metabolic process, starting with the harmful recognition and activation of the inflammasome, continues the energy supply with the alteration of oxidative stress conditions, and finishes with the elimination of the aggression with autophagy/apoptosis mechanisms, then concludes with recovery...

BACKGROUND: The present study assessed the association between periodontal pathogen colonization and the potential risk of developing precancerous lesions of gastric cancer (PLGC) in a clinical setting. METHODS: The present study included 35 newly diagnosed patients with PLGC and 70 age-matched individuals without PLGC. A full-mouth intra-oral examination was performed to assess the periodontal conditions. Stimulated whole saliva and pooled plaque samples were collected to evaluate colonization by Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia and Actinobacillus actinomycetemcomitans and to characterize the oral microbial diversity in the saliva and dental plaque...

OBJECTIVES: Aggregatibacter actinomycetemcomitans is a recognised pathogen involved in aggressive periodontitis. Seven serotypes of A. actinomycetemcomitans exist with a range of virulence and distribution dependent on ethnicity and geography. The ability of A. actinomycetemcomitans to invade soft tissue can necessitate the use of systemic antibiotics for treatment, however variations in its antibiotic susceptibility exist dependent on geographical location. METHODS: Serotypes of A...

BACKGROUND: The virulence of Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans) in any individual depends on the type of strain of this bacterium. To our knowledge, there have been no studies reported in Indian subjects about A. actinomycetemcomitans serotype occurrence, co-existence with herpes virus and the possible influence of such co-existence on periodontal pathology. METHODS: Subjects for this study were a subset of a larger study to identify the prevalence of A...
