A seamless platform for dentists and patients to discover each other and engage with one another in a mutually rewarding way.

Newport Beach, CA – July 08 2015 – The dentist-patient communication newcomer Denteractive announced today the availability of a new mobile application that will  significantly enhance dentist-patient interaction, engagement and communication. Denteractive is a mobile and web friendly, dentist-patient engagement and collaboration platform designed to help dental care professionals and patients engage one another from the comfort of their home, office or when they’re on-the-go. Highly secured with encryption protection (following HIPAA guidelines for privacy), Denteractive members can have live interactions by text, phone, and/or video for the purposes of introductory meetings, consultations and education, exchange of information and files, preventive treatment, tracking dental treatment history, and appointment bookings.

In addition, Denteractive helps dental care professionals boost their digital presence through personal and relationship marketing tools. Denteractive  helps dental care professionals with increased brand awareness, product and service exposure, patient engagement and dental transactions.
According to the company’s Founder and CEO, Reza Izadi, D.D.S. “Dentistry in the U.S. is in a great state of transformation. The population is aging and becoming more diverse. The mix of consumer logic and choice for seeking dental-care services is changing more than ever demanding advanced dental technologies and greater value for services. Today, more than half of the economic value of dental care comes from procedures that were not available two decades ago. With shifting interests on the part of patients, evolving technology, and new delivery factors continuing to emerge, it seems reasonable to expect a future marked by additional change.”
Hospital emergency departments draw millions of patients where cost is tremendously expensive. The lack of insurance, geographical isolation, poor diet and oral hygiene, being out of the area or after-hours all contribute to the oral conditions that drive people to hospitals where the vast majority of visitors don’t even receive proper dental treatment, but are instead treated with prescription medications. Estimates also show that a third of Americans don’t even have a primary dentist they see each year. People relocate or start new jobs, while others start new insurance policies not accepted by their current primary dentist. 
Denteractive is the only dentist-patient platform where consumers are the closest to the dental care professionals even before their office visits. It is a platform of users' actions-reactions designed to boost preventive care and population health through education on one end, and dentist brand awareness and product exposure at the other end every step of the way. “Denteractive™ is the optimal mix of mobile patient engagement, patient education, dental marketing, and information technology working together to promote population health, and support dental practice's productivity and profitability”, says the company CEO.

American Academy of Periodontology: More Than a Quarter of US Adults are Dishonest with Dentists about Flossing Habits

National survey reveals there’s room for improvement to educate Americans on gum disease, which affects one in every two adults over age 30

CHICAGO (June 29, 2015)–As part of its national “Love the Gums You’re With” campaign, the American Academy of Periodontology (AAP) released a new national survey that reveals more than a quarter (27 percent) of U.S. adults admit they lie to their dentist about how often they floss their teeth.

Additionally, more than one-third of Americans (36 percent) would rather do an unpleasant activity over daily flossing such as cleaning the toilet (14 percent), washing a sink full of dirty dishes (18 percent), or waiting in a long checkout line (14 percent). Moreover, nearly one in ten US adults would rather sit in gridlock traffic for an hour or do their taxes (9 percent each).

The online survey was conducted within the United States between March 20-24, 2015, among 2,021 adults ages 18 and older by Harris Poll, on behalf of AAP via its QuickQuery omnibus product, and from March 24-30, 2015, via its Major Market Query omnibus product among the following top 10 US markets: New York City (n=212), Los Angeles (n=211), Chicago (n=212), Philadelphia (n=211), Dallas-Fort Worth (n=212), San Francisco (n=214), Boston (n=212), Washington, DC (n=213), Atlanta (n=210), and Houston (n=209). Figures for age, sex, race/ethnicity, education, region, and household income were weighted where necessary to bring them in line with their actual proportions in the population. Propensity score weighting was used to adjust for respondents’ propensity to be online. 

Interestingly, the survey also revealed some regional distinctions in oral healthcare. Among the top 10 U.S. markets, Chicagoans are more likely than those in other regions to opt for an hour of gridlock traffic over daily flossing. However, New Yorkers are more likely than those in other metro areas to include flossing in their personal care routine.

Southern manners could also be at play. Those who live in Atlanta are more likely than those in other top metro regions to be honest with their dentist about their flossing routine. Atlantans also are more likely than those in other top metro regions to tell friends when they have something stuck in their teeth. On the contrary, those who live in DC are more likely than those in other top metro regions not to alert a friend of any potentially embarrassing lunch leftovers.

In addition, three in five (60 percent) US adults who have a partner say their partner’s oral health has an effect on their intimacy, while over a third of Americans say a smile is the first thing they notice when meeting someone they are attracted to. In fact, more than two in five of those living in Los Angeles, Atlanta, and Boston say a smile is the first thing they notice when meeting someone they are attracted to. This is especially true for women.

Launched in April 2014, the AAP’s “Love the Gums You’re With” campaign is aimed at teaching Americans to take better care of their gums by implementing simple steps into their routine such as brushing twice a day, flossing daily, and receiving an annual comprehensive periodontal evaluation from their dental professional or periodontist. Despite its prevalence, periodontal disease is hardly ever discussed, resulting in a lack of urgency for people to properly care for their gums.

“There’s clearly more work to be done when it comes to educating Americans about the importance of oral hygiene,” remarked AAP President Joan Otomo-Corgel, DDS, MPH. “There are more than 500 bacterial species that can be found in plaque, and brushing alone does not remove the bacteria that live below the gum line. The good news about periodontal disease is, with proper and timely care, it’s treatable and often reversible. If a person is at risk for periodontal disease, a periodontist has the training and expertise to determine the best course of treatment.”

Study: Alcohol Consumption Can Have a Negative Impact on Gum Health Recent Study Published in the Journal of Periodontology (JOP) Reveals that Drinking May Increase Periodontal Disease Risk Factors, Exacerbate Existing Periodontitis

CHICAGO (June 29, 2015)—In a recent study published ahead of print in the Journal of Periodontology, Brazilian researchers have found that consumption of alcoholic beverages can have adverse effects on the health of a person’s gums, aggravating existing cases of severe periodontal disease or increasing periodontal disease risk factors. Moreover, previous research indicates that poor oral hygiene is a common trait in alcohol users, thus increasing drinkers’ susceptibility for developing periodontal disease. 
“Although the topic of alcohol use and its effect on periodontal health requires further research, this report offers valuable insight on why our patients should care for their gums and teeth, especially if they enjoy the occasional drink,” remarked Joan Otomo-Corgel, DDS, MPH, President of the American Academy of Periodontology.
In the study entitled, “Alcohol Consumption and Periodontitis: Quantification of Periodontal Pathogens and Cytokines,” researchers assessed a sample of 542 regular alcohol users, occasional drinkers, and non-drinkers both with and without periodontitis. 
Some key findings noted in the study include:
  • The severity of a regular alcohol user’s existing periodontitis correlated incrementally with the frequency of his or her alcohol consumption. As a result, these individuals were found to require additional periodontal treatment. 
  • Drinkers without periodontitis saw an increased incidence of gums that bled with gentle manipulation. 
  • More frequently than the non-drinkers in the study, drinkers who did not have periodontitis presented clinical attachment levels of four millimeters or greater. 
  • Drinkers without periodontitis exhibited a higher presence of plaque than their non-drinking counterparts. Study researchers noted that alcohol’s drying effect on the mouth may contribute to the formation of plaque that can trigger an inflammatory response in the gums. 
“Alcohol slows the production of saliva, which helps neutralize the acids produced by plaque, and an accumulation of these acids can lead to the early stages of periodontal disease,” continued Dr. Otomo-Corgel. “For patients who are diagnosed with periodontal disease, it’s imperative that they are encouraged to be completely honest about their drinking habits. This information can guide in determining appropriate treatment and next steps.”
A full version of “Alcohol Consumption and Periodontitis: Quantification of Periodontal Pathogens and Cytokines,” study can be found in an upcoming print edition of the Journal of Periodontology.

Long-term clinical, technical, and esthetic outcomes of all-ceramic vs. titanium abutments on implant supporting single-tooth reconstructions after at least 5 years



The aim of this prospective cohort study was to evaluate clinical, radiographic, technical, esthetic, and patient-centered outcomes of implants using two different restoration materials after 5–9 years.

Materials and Methods

The study included 28 patients (test group: 13 patients with all-ceramic crowns on aluminum oxide-based abutments; control group: 15 patients with metal abutments on porcelain-fused-to-metal crowns). Evaluation of patient satisfaction, clinical (periodontal probing depth, bleeding on probing, plaque index, mucosal recession, and width of keratinized mucosa), esthetical (papilla index, clinical crown length), technical (loss of retention, marginal adaptation, chipping of ceramic, anatomical shape, occlusal wear, color match), and radiological parameters were assessed. The statistical analyses included comparison of all-ceramic vs. metal abutments and between the groups using Mann–Whitney U-tests. For esthetic parameters, changes over time were assessed using Friedman test and post hoc Wilcoxon test of all complete cases.


The survival rate of the restoration was 100% in both groups. Patient's satisfaction revealed 9.7 on the visual analog scale. A low satisfaction correlated with low ratings in color or anatomical shape. The mucosal recession in the test group was less than that in the control group. An increase in distal papilla height in the year 0 to 1, and a decrease from year 1 to 8, was detected. Sites, which received a soft tissue graft, revealed stable papillae over the observation period. Clinical crown length showed higher values in the control group.


Within the limitations of the study, it can be concluded that all-ceramic restorations reveal a high survival rate of 100% and show no difference to metal after a mean observation period of 7.2 years.

Systemic antibiotics in the treatment of aggressive periodontitis. A systematic review and a Bayesian Network meta-analysis.

J Clin Periodontol. 2015 Jun 19. doi: 10.1111/jcpe.12427. [Epub ahead of print]



The aim of this study was to assess the effect of systemic antibiotic therapy on the treatment of aggressive periodontitis (AgP).


This study was conducted and reported in accordance with the PRISMA statement. The MEDLINE, EMBASE, and CENTRAL databases were searched up to June 2014 for randomized clinical trials comparing the treatment of subjects with AgP with either scaling and root planing (SRP) alone or associated with systemic antibiotics. Bayesian network meta-analysis was prepared using the Bayesian random-effects hierarchical models and the outcomes reported at 6-month post-treatment.


Out of 350 papers identified, 14 studies were eligible. Greater gain in clinical attachment (CA) (mean difference [MD]: 1.08 mm; p<0 .0001="" 0.45="" 0.53="" 1.05="" additional="" alone="" amoxicillin="" and="" antibiotics.="" associated="" bayesian="" benefits="" ca="" depth="" for="" gain="" in="" md:="" meta-analysis="" metronidazole="" mm="" mx="" network="" observed="" p="" pd="" placebo.="" probing="" reduction="" respectively="" showed="" srp="" systemic="" than="" tz="" was="" were="" when="" with="">


SRP plus systemic antibiotics led to an additional clinical effect compared with SRP alone in the treatment of AgP. Of the antibiotic protocols available for inclusion into the Bayesian network meta-analysis, Mtz and Mtz/Amx provided to the most beneficial outcomes. This article is protected by copyright.

Comparison of the marginal fit of lithium disilicate crowns fabricated with CAD/CAM technology by using conventional impressions and two intraoral digital scanners


Statement of problem

Conventional impression materials and techniques have been used successfully to fabricate fixed restorations. Recently, digital pathways have been developed, but insufficient data are available regarding their marginal accuracy.


The purpose of this in vitro study was to compare the marginal gap discrepancy of lithium disilicate single crowns fabricated with computer-aided design and computer-aided manufacturing (CAD/CAM) technology by using both conventional and 2 digital impression techniques.

Material and methods

One typodont maxillary right central incisor was prepared for a ceramic crown. Ten impressions were made by using each method: conventional with polyvinyl siloxane impression material, Lava COS (3M ESPE), and iTero (Cadent) intraoral scanning devices. Lithium disilicate (e.max CAD) crowns were fabricated with CAD/CAM technology, and the marginal gap was measured for each specimen at 4 points under magnification with a stereomicroscope. The mean measurement for each location and overall mean gap size by group were calculated. Statistically significant differences among the impression techniques were tested with F and t tests (α=.05).


The average (±SD) gap for the conventional impression group was 112.3 (±35.3) μm. The digital impression groups had similar average gap sizes; the Lava group was 89.8 (±25.4) μm, and the iTero group was 89.6 (±30.1) μm. No statistically significant difference was found in the effects among impression techniques (P=.185)


Within the limitations of this study, digital and conventional impressions were found to produce crowns with similar marginal accuracy.

Responses of Human Dental Pulp Cells after Application of a Low-concentration Bleaching Gel to Enamel

  1. Archives of Oral Biology 
    Published Online: June 20, 2015




to evaluate the effect of a 17.5% H2O2 gel on the odontoblastic differentiation capability of human dental pulp cells (HDPCs).


The bleaching gel was applied for 45, 15, or 5 minutes to enamel/dentin discs adapted to transwells, positioned over previously cultured HDPCs. In the control group, no treatment was performed on the discs. Immediately after samples were bleached, the cell viability (MTT assay) and death (Live/Dead assay) as well as the mRNA gene expression of inflammatory mediators (TNFα, IL-1β, IL-6, and COX-2; real-time PCR) were evaluated. The mRNA gene expression of odontoblastic markers (DMP-1, DSPP, and ALP) and mineralized nodule deposition (alizarin red) were assessed at 7, 14, and 21 days post-bleaching. The amount of H2O2 in contact with cells was quantified. Data were evaluated by Kruskal-Wallis and Mann-Whitney tests (α = 5%).


Significant cell viability reduction and cell death were observed for bleached groups relative to control in a time-dependent fashion. Also, significant overexpression of all inflammatory mediators tested occurred in the 45- and 15-minute groups. In the bleached groups, the expression of ALP, DMP-1, and DSPP and the deposition of mineralized nodules were reduced in comparison with those in the control group, at the initial periods (7 and 14 days). However, the 15- and 5-minute groups reached values similar to those in the control group at the 21-day period.


The 17.5%-H2O2 gel was cytotoxic to pulp cells; however, cells subjected to short-term bleaching are capable of expressing the odontoblastic phenotype over time.
