Dental biofilms are characterized by structural and functional heterogeneity. Due to bacterial metabolism, gradients develop and diverse ecological microniches exist. The aims of this study were (i) to determine the metabolic activity of microorganisms in naturally grown dental biofilms ex vivo by measuring dissolved oxygen (DO) and pH profiles with mlcroelectrodes with high spatial resolution and (ii) to analyze the impact of an antimicrobial Chlorhexidine (CHX) treatment on microbial physiology during stimulation by sucrose in real time. Biofilms were cultivated on standardized human enamel surfaces in vivo. DO and pH profiles were measured in a flow cell system in sterile human saliva, after sucrose addition (10%), again after alternative treatment of the sucrose exposed biofilms with CHX (0.2%) for 1 or 10 min or after being killed with paraformaldehyde (4%). Biofilm structure was visualized by vitality staining with confocal microscopy. With saliva as the sole nutrient source oxygen consumption was high within the superficial biofilm layers rendering deeper layers (>220 μm) anoxic. Sucrose addition induced the thickness of the anaerobic zone to increase with a concurrent decrease in pH (7.1 to 4.4). CHX exposure reduced metabolic activity and microbial viability at the biofilm surface and drove metabolic activity deeper into the biofilm. CHX treatment led to a reduced viability at the biofilm surface with minor influence on overall biofilm physiology after 1 min; even after 10 min there was measurable respiration and fermentation inside the biofilm. However, the local microenvironment was more aerated, less acidogenic, and presumably less pathogenic. Copyright © 2010, American Society for Microbiology. All Rights Reserved.

Objective: The aim of this study was to investigate the oral mucosal disorders associated with habitual gutka consumption. Methods: Databases were searched from 1956 to June 2009 using the following terms: "gutka," "gutkha," "ghutka," "guttkha," "smokeless tobacco," "areca nut," "betel nut," "slaked lime," "dental," "oral," "periodontal," "inflammation," "submucous fibrosis," "carcinoma," and "cancer." The eligibility criteria included: human and experimental studies, use of control subjects, and articles published in English. Unpublished data were not sought. Odds ratios (ORs) and 95% confidence intervals (CIs) were computed. Results: Twelve studies were included. Three studies associated gutka consumption with periodontal inflammation (ORs 1.64 [CI 1.2-2.1], 2.20 [CI 1.1-4.9], and 3.56 [CI 1.9-5.5]). Five studies showed a direct relationship between gutka usage and oral submucous fibrosis (ORs 1.65 [CI 1.2-2.3], 2.33 [CI 1.9-4.5], 2.98 [CI 1.5-3.9], 3.56 [CI 1.3-4.7], and 5.08 [CI 3.7-6.4]). An increased frequency of gutka usage was associated with malignant transformations in oral submucous fibrosis by 2 studies (ORs 4.59 [CI 2-5.6] and 18 [CI 5.8-61.6]). Two studies showed an extension of oral submucous fibrosis into the hypopharynx and esophagus in gutka users (ORs 4.59 [CI 2-5.6] and 33 [CI 2.2-46.6]). Conclusions: Habitual gutka usage is associated with severe oral mucosal disorders, and the consequences may extend beyond the oral cavity. © 2010 Mosby, Inc. All rights reserved.

Aim: The adverse effects of areca nut (AN) chewing habit on oral health have been reported. However, the hazards related to the habit are not restricted to the oral cavity but they can also jeopardise the systemic health. Since no review reporting the harmful effects of AN chewing on systemic health is yet available, the aim of the present study was to review the systemic conditions associated with AN usage. Methods: To address the focused question "What are the deleterious effects of AN usage on systemic health?", the MEDLINE PubMed databases were explored from 1966 up to and including May 2010. The eligibility criteria included: human studies, individuals using AN, use of controls, and articles published in English. Hand-searching was also performed. Unpublished data was excluded. Results: The review included 28 articles. Seven studies associated AN chewing with cardiovascular disorders and three studies related the habit with cerebrovascular disorders. Eight studies related AN chewing with obesity, hyperglycaemia, metabolic syndrome, and type 2 diabetes mellitus. Five studies related AN chewing with the development of hepatic disorders. Two studies associated the chewing habit with oesophageal inflammation and fibrosis. Three studies associated AN chewing with respiratory discomfort. Renal disorders were related with the chewing abuse in two studies. Two studies showed an adverse effect of AN chewing on birth outcome. Conclusions: AN chewing adversely affects systemic health by damaging the vital organs. © 2010 the Nordic Societies of Public Health.

To evaluate the effectiveness of desensitizing toothpaste containing 5.53% potassium citrate on dentine hypersensitivity. This was a randomized, double-blinded, controlled, clinical trial. Those, who satisfied the inclusion criteria, were recruited into the study and randomized allocated into test group and control group according to gender and age group. At baseline, 67 subjects (36 in test group, 31 in control group) were recruited into the study. The dentine hypersensitivity was evaluated by a subject self-perceived short, sharp pain in visual analogue scale (VAS) in response to a blast of cold air from a triple syringe administered to a tooth surface in 1 cm. Test toothpastes, containing 5.53% potassium citrate and 0.76% sodium monofluorophosphate, and control toothpastes, containing only 0.76% sodium monofluorophosphate were delivered to the study subjects in the test and control group respectively. The subjects were asked to brush their teeth twice a day, and at least one minute each time. During the 8-week study period, a subjective evaluation of changes in the individuals overall sensitivity to everyday stimuli was also scored in VAS. At the end of the trial data of 57 subjects (31 in test group, 26 in control group) was used for analysis. From baseline to 8-week evaluation, the mean VAS values to cold air and subjects' self-perceived VAS values of the subjects decreased both in the test and control groups. Furthermore, the reduction in mean VAS values to cold air from baseline to 4-week of the test subjects was statistically significant higher than that of the control (1.12 vs. 0.32, P<0.05). The reduction in mean subjects' self-perceived VAS values from baseline to 8-week of the test subjects was statistically significant higher than that of the control (1.59 vs. 0.24, P<0.05). RESULTS of the clinical trial showed that toothpastes containing 5.53% potassium citrate were effective in reducing dentine hypersensitivity.

The aim of this study was to evaluate the anti-erosive effects of different fluoride compounds and one tin compound in the context of the complex pathohistology of dentine erosion, with particular emphasis on the role of the organic portion. Samples were subjected to two experiments including erosive acid attacks (0.05 molar citric acid, pH 2.3; 6 × 2 min/day) and applications (6 × 2 min/day) of the following test solutions: SnCl 2 (815 ppm Sn), NaF (250 ppm F), SnF2 (250 ppm F, 809 ppm Sn), amine fluoride (AmF, 250 ppm F), AmF/NaF (250 ppm F), and AmF/SnF 2 (250 ppm F, 409 ppm Sn). The demineralised organic fraction was enzymatically removed either at the end of the experiment (experiment 1) or continuously throughout the experiment (experiment 2). Tissue loss was determined profilometrically after 10 experimental days. In experiment 1, the highest erosive tissue loss was found in the control group (erosion only); the AmF- and NaF-containing solutions reduced tissue loss by about 60%, reductions for SnCl2, AmF/SnF2, and SnF2 were 52, 74 and 89%, respectively. In experiment 2, loss values generally were significantly higher, and the differences between the test solutions were much more distinct. Reduction of tissue loss was between 12 and 34% for the AmF- and NaF-containing preparations, and 11, 67 and 78% for SnCl2, AmF/SnF2, and SnF2, respectively. Stannous fluoride-containing solutions revealed promising anti-erosive effects in dentine. The strikingly different outcomes in the two experiments suggest reconsidering current methodologies for investigating anti-erosive strategies in dentine. Copyright © 2010 S. Karger AG.

Objective: Keratocystic odontogenic tumour (KCOT) is a benign uni- or multicystic intraosseous odontogenic tumour with potential for local destruction and tendency for multiplicity, especially when associated with Gorlin-Goltz syndrome. We suggest a conservative surgical treatment based on marsupialization and later enucleation with peripheral ostectomy in order to preserve jaw's integrity in young patients. Methods: Three young patients affected of nevoid basal cell carcinoma syndrome (NBCCS or Gorlin-Goltz syndrome) presented large and multiple KCOTs, which have been treated following a two-stage surgical strategy. Initially marsupialization was performed and after a mean period of 10 months, contextually to evident reduction in radiological size image, enucleation with peripheral ostectomy was carried out. Results: All the patients showed high collaboration in daily self-irrigation of the stomia with chlorhexidine 0.2% during the period of marsupialization. Definitive surgical intervention led to complete healing and no signs of recurrence have been observed during a 5-year-follow-up. Conclusions: The main advantage of this modality is the preservation of important anatomical structures involved in the lesion and jaw's continuity. Therefore in a selected group of cooperative patients, especially those affected of Gorlin-Goltz syndrome, the surgical protocol exposed allows for a less invasive approach with excellent results avoiding extensive disfiguring procedures. © 2011.

Objectives To test the in vivo effects of an ultrasonic dental scaler on various implanted cardioverter defibrillator (ICD) models. Methods 12 consecutive patients with ICDs had continuous both electrocardiogram monitoring and device interrogation to detect interferences during the use of an ultrasonic dental scaler. Results No interferences were detected by any ICD. Evaluation of the electrocardiograms for each patient failed to show any abnormalities in pacing during testing. Conclusion The results of this study suggest that the routinary clinic use of piezoelectric dental scalers do not interfere with the functioning of any of the tested ICDs. Clinical significance Ultrasonic dental scalers have been suspected of electromagnetic interference (EMI) with the normal functioning of ICDs and the use of this type of equipment for patients with these devices has been controversial. This is the first in vivo study to investigate EMI of ICD activity during the operation with ultrasonic dental scaler. © 2013 Elsevier Ltd.

Objectives: The purpose of this study is to clinically and radiographically evaluate survival and success rate of multiple zirconia dental implants positioned in each patient during a follow-up period of at least 12 months up to 48 months. Study Design: Eight patients were treated for multiple edentulism with 29 zirconia dental implants. All implants received immediate temporary restorations and 6 months after surgery were definitively restored. 6 months to 4 years after implant insertion, a clinical-radiographic evaluation was performed in order to estimate peri-implant tissues health and peri-implant marginal bone loss. Results: Survival rate within follow-up period was therefore 100%. The average marginal bone loss (MBL) from baseline to 6 months was +1.375±0.388 mm; from 6 months to 1 year was +0.22±0.598 mm; from 1 year to 2 years was -0.368±0.387 mm; from 2 years to 3 years was -0.0669±0.425 mm; from 3 years to 4 years +0.048±0.262 mm. The mean marginal bone loss at 4 years from the implants insertion was +1.208 mm. Conclusions: According to several studies, when using a radiographic criterion for implant success, marginal bone loss below 0.9-1.6 mm during the first year in function can be considered acceptable. In our work, radiographic measurements of MBL showed values not exceeding 1.6 mm during the first year of loading and also 1 year up to 4 years after surgery further marginal bone loss was minimal and not significant. This peri-implant bone preservation may be associated to the absence of micro-gap between fixture and abutment since zirconia dental implants are one-piece implant. Moreover, zirconia is characterized by high biocompatibility and it accumulates significantly fewer bacteria than titanium. © Medicina Oral S. L.
