OBJECTIVE: To describe an oral health care programme for older people in Residential Aged Care Facilities (RACFs) to improve access to care and support facilities. INTRODUCTION: Different models of residential care have been proposed, but few have been comprehensive (providing on-site health promotion and service delivery) or sustainable. METHODS: A partnership model of oral health care, with dental services plus oral health education, was integrated into the community outreach services of a metropolitan hospital department of aged care...

BACKGROUND AND AIM: Pain control is an important outcome measure for successful periodontal therapy. Injected local anesthesia has been used to secure anesthesia for scaling and root planing (SRP) and continues to be the anesthetic of choice for pain control. Alternatively, intra-pocket anesthetic gel has been used as an anesthetic during SRP. Hence, this clinical trial was done to compare the effectiveness of intra-pocket anesthetic gel and injected local anesthesia during SRP and also to assess the influence of intra-pocket anesthetic gel on treatment outcomes in chronic periodontitis patients...

An oral health survey was conducted in 829 individuals in different age groups in Ballabhgarh, Haryana, India, to estimate the prevalence of Dental caries and Periodontal diseases. A survey tool was modified from WHO's STEPwise approach to surveillance and Oral Health Assessment form 2013 from recently released WHO Oral Health Survey: Basic Methods (5th Edition) keeping in mind the South East Asian region. Out of 28 villages, six villages were randomly selected. A random list of study participants (Age-sex specific) was generated from the pooled list of these 6 villages...

Periodontitis is a multifactorial infectious disease that affects a large population worldwide. It involves progressive alveolar bone loss, and if left untreated, can lead to the loosening and subsequent loss of teeth. Oral microorganisms and susceptible host have been proposed to be the prerequisite for the development of periodontitis. Aberrant host immune response is the key factor that leads to the destruction of periodontal tissues. Recently, the involvement of epigenetic modifications in the development of periodontitis has attracted increasing attentions...

Biofilm is an extremely complex microbial community arranged in a matrix of polysaccharides and attached to a substrate. Its development is crucial in the pathophysiology of oral infections like dental caries, as well as in periodontal, pulp, and periapical diseases. Streptococcus mutans is one of the most effective microorganisms in lactic acid production of the dental biofilm. Identifying essential Streptococcus mutans proteins using bioinformatics methods helps to search for alternative therapies. To this end, the bacterial genomes of several Streptococcus mutans strains and representative strains of other cariogenic and non-cariogenic bacteria were analysed by identifying pathogenicity islands and alignments with other bacteria, and by detecting the exclusive genes of cariogenic species in comparison to the non-pathogenic ones...

PURPOSE: This study evaluates the synergistic effect of serial application of bone morphogenetic protein 2 (BMP2) and fibroblast growth factor 2 (FGF2) on both new bone formation and periodontal tissue regeneration using 1-wall intrabony defect in mongrel dogs. MATERIALS AND METHODS: One-wall defects were created at the mesial aspect of the mandibular first molars of 6 male mongrel dogs. Each mandibular defect received 1 of the 2 experimental treatments randomly (BMP2 or BMP2 + FGF2), and it was allowed to heal for either 4 or 8 weeks postoperatively...

Enterococcus faecalis is occurring in opportunistic infections involving the oral cavity. This study aimed to evaluate the presence of E. faecalis virulence genes in dental root canal isolates recovered from advanced chronic periodontitis patients. One hundred E. faecalis isolated from dental root canal during July 2015 to Oct 2016. After analysis of biofilm formation by the semi-quantitative determination in 96-well flat bottom polystyrene plates, the presence of asa, esp, efaA, ace, ebpR, gel and hyl gene were studied by PCR...

In this second part of a diptych on bruxism, the focus is on the associations of this masticatory muscle activity with other sleep-related conditions. Its association with the obstructive sleep apnoea syndrome (OSAS) has been a particular object of study. Bruxism seems to play a protective role in OSAS, although the evidence for this is not yet conclusive. Apart from this possible positive consequence, bruxism also has several negative consequences, for which evidence is available to a greater or lesser extent...

Halitosis or bad breath is a problem that affects many people and its source is generally found in the oral cavity (intra-oral halitosis). Bacteria in the oral cavity produce volatile sulphur compounds such as hydrogen sulphide and methyl mercaptan that not only emit an unpleasant odour, but may also have toxic effects on the periodontal tissues. Good oral hygiene, a healthy periodontium and healthy teeth are the basis for the prevention of intra-oral halitosis and dentists and dental hygienists therefore play an essential role in its prevention...

Platelet-rich plasma (PRP) contains growth factors which positively affect cell proliferation, cell differentiation, chemotaxis and intracellular matrix synthesis. All these processes are involved in wound healing and tissue regeneration; thus, PRP as a source of growth factors can be used in periodontal regenerative therapies. The purpose of the present study was to assess the effect of various concentrations of activated and non-activated PRP on proliferation of osteoblasts and fibroblasts in vitro. PRP was obtained from three healthy volunteers...

BACKGROUND/AIM: An avulsed tooth must be stored in a solution which maintains periodontal ligament (PDL) cell viability. The aim of this study was to compare the effects of Hank's Balanced Salt Solution (HBSS) and milk on the differentiation of PDL fibroblasts. MATERIAL AND METHODS: Eighteen extracted third molars, (n = 3 for each group), were immersed in HBSS, milk, and Dulbecco's Modified Eagle Medium-Ham's F12 (DMEM-F12) at 4 °C for 30-60 min or 12 h. The growth dynamics of PDL fibroblasts were evaluated with cell proliferation graphics and population doubling time (PDT) values...

Claudiu T Supuran, Clemente Capasso
Periodontitis originates from a microbial synergy causing the development of a mouth microbial imbalance (dysbiosis), consisting of a microbial community composed of anaerobic bacteria. Most studies concerning the treatment of periodontitis have primarily take into account the Gram-negative bacterium Porphyromonas gingivalis, because it is a prominent component of the oral microbiome and a successful colonizer of the oral epithelium. Here, we focus our attention on the study of the carbonic anhydrases (CAs, EC 4...

Researches have shown positive correlation between periodontitis and respiratory diseases such as chronic obstructive pulmonary disease. We reviewed the literature to assess the relationship between periodontitis and respiratory diseases. This study involved a review of relevant English literature published regarding periodontitis and respiratory diseases during the period of 1994-2015. The analysis of literature related to the topic showed there is association between periodontitis and respiratory diseases such as chronic obstructive pulmonary disease and pneumonia...

The use of stem cell-derived sheets has become increasingly common in a wide variety of biomedical applications. Although substantial evidence has demonstrated that human platelet lysate (PL) can be used for therapeutic cell expansion, either as a substitute for or as a supplement to xenogeneic fetal bovine serum (FBS), its impact on cell sheet production remains largely unexplored. In this study, we manufactured periodontal ligament stem cell (PDLSC) sheets in vitro by incubating PDLSCs in sheet-induction media supplemented with various ratios of PL and FBS, i...

There are anatomical and functional differences between human dental pulp (DP) and periodontal ligament (PDL). However, the molecular biological differences and function of these tissues are poorly understood. In the present study, we employed a cDNA microarray array to screen for differentially expressed genes (DEGs) between human DP and PDL tissues, and used the online software WebGestalt to perform the functional analysis of the DEGs. In addition, the STRING database and KEGG pathway analysis were applied for interaction network and pathway analysis of the DEGs...
