Oral hygiene and periodontal health status among khat chewers. A case-control study

2016

Background Habitual khat chewing is a widespread male habit in Southern Arabia and East Africa. The aim of this study was to assess the effect of Khat chewing on oral hygiene and periodontal health status among Yemeni male khat chewers. Material and Methods This case- control study included 310 khat chewers, aged 20-65 years, and 72 age- and gender- matched non-chewers as controls. Periodontal examination included recording of dental plaque index (PI), gingival index (GI), probing pocket depth (PPD), attachment level (AL) and gingival recession (GR). Demographic data, oral hygiene practices, and duration, frequency and site of khat chewing were obtained using questionnaires. SPSS was used f…

Mesenchymal dental stem cells in regenerative dentistry

2012

In the last decade, tissue engineering is a field that has been suffering an enormous expansion in the regenerative medicine and dentistry. The use of cells as mesenchymal dental stem cells of easy access for dentist and oral surgeon, immunosuppressive properties, high proliferation and capacity to differentiate into odontoblasts, cementoblasts, osteoblasts and other cells implicated in the teeth, suppose a good perspective of future in the clinical dentistry. However, is necessary advance in the known of growth factors and signalling molecules implicated in tooth development and regeneration of different structures of teeth. Furthermore, these cells need a fabulous scaffold that facility t…

Comparison of radiovisiography and digital volume tomography to direct surgical measurements in the detection of infrabony defects

2012

Objectives: To compare the linear measurements of Radiovisiography (RVG) and Digital volume tomography (DVT) to direct surgical measurements in the detection of periodontal infrabony defects. Study Design: RVG and DVT images were taken prior to periodontal surgery for 28 infrabony periodontal defects. After defect debridement, direct bony defect measurements were made from the cemento enamel junction (CEJ) to the base of the defect (CEJ-BD) and to the alveolar crest (CEJ-AC) with a periodontal probe. These same measurements were made on the RVG and DVT images and then compared to the direct surgical values. Results: DVT correlated strongly with surgical measurements, whereas RVG correlated …

Comparative in vitro study of two methods for gingival biotype assessment

2018

Background The gingival thickness seems to have an important role in different dental treatments. There are different methods of quantifying this thickness, but it is not known which of them can be the most effective. The objective to assess the accuracy of two different methods for gingival thickness measurement: the transgingival needle probing (TGNP) and the tension-free caliper (TFC) in an in vitro model, by comparing them with direct physical measurements (reference standard). Material and methods Gingival thickness (GT) was evaluated in 27 female pigs with four implant sites 1, 2 and 3mm from the gingival margin with three different methods: 1) transgingival needle probing 2) tension-…

Etiology and Prevalence of Gingival Recession

2018

Gingival recession is a highly prevalent problem affecting individuals of all ages worldwide. Before considering any therapeutic strategies for gingival recession defects, it is important to identify the underlying etiological factors that contributed to the development of the clinical condition. The main etiological factors for gingival recession are plaque-induced periodontal inflammation and mechanical trauma caused by improper toothbrushing habits. Several other predisposing and precipitating factors have also been implicated in the etiology of gingival recession. The aim of this chapter is to summarize the different etiological factors contributing to the development of gingival recess…

Histologic Evaluation of Human Intrabony Defects Following Non-Surgical Periodontal Therapy With and Without Application of an Enamel Matrix Protein …

2003

Background: Surgical periodontal treatment with enamel matrix protein derivative (EMD) has been shown to promote periodontal regeneration. However, it is not known whether nonsurgical periodontal therapy with additional subgingival application of EMD may also enhance periodontal regeneration. The purpose of this study was to clinically and histologically evaluate healing of human intrabony defects following non-surgical periodontal treatment with and without application of EMD. Methods: Sixteen patients, each of whom displayed one advanced intrabony defect around teeth or roots scheduled for extraction, were included in the study. The defects were treated as follows: 1) scaling and root pla…

The efficacy of 8% Arginine-CaCO3 applications on dentine hypersensitivity following periodontal therapy: a clinical and scanning electron microscopi…

2013

Objectives: Periodontal therapy is one of the etiological factors of dentine hypersensitivity (DH). This study aimed to evaluate the efficacy of %8Arginine-CaCO3 on DH that affects patients after periodontal treatment. Study design: Seventy-one teeth from the volunteers (n=36) with history of DH caused by periodontal therapy were included in this study, and randomly divided into two groups: group-1, who received 8%Arginine-CaCO3 and group-2, who received 1.23%NaF-gel. The clinical indices were recorded at first visit.DH was evaluated by using tactile, air-blast, and thermal stimuli. The subject’s response was recorded at baseline, immediately (Day-0) and one month after the application. Res…

Periodontitis and mechanisms of cardiometabolic risk: Novel insights and future perspectives

2019

Periodontitis is an infectious and inflammatory disease of the tooth-supporting tissues caused by the accumulation of subgingival plaque and the action of specific periodontopathogenic bacteria. Periodontitis has been associated with cardiovascular diseases and considered a cardiovascular risk factor. Several mechanisms have been proposed to explain this association, such as the infection of atherosclerotic plaques by periodontal pathogens, the pro-atherogenic effect on the lipid profile, the systemic dissemination of pro-inflammatory mediators or the contribution to type 2 diabetes mellitus. Periodontal treatment has also been related to improvement in cardiometabolic risk variables, and o…

A case series associated with different kinds of endo-perio lesions

2014

Pulpal and periodontal problems are responsible for more than half of the tooth mortality. There are some articles published in the literature about this issue. Many of them are quite old. There has been also lack of knowledge about the effect of endodontic treatment on the periodontal tissue healing and suitable treatment interval between endodontic and periodontal treatments. In this case report, different kinds of endo-perio lesion were treated with sequential endodontic and periodontal treatment. The follow-up radiographs showed complete healing of the hard and soft tissue lesions. The tooth with endo-perio lesions should be evaluated thoroughly in terms of any cracks and fracture, espe…
