Mouth Breathing Can Cause Major Health Problems
The physical, medical and social problems associated with mouth breathing are not recognized by most health care professionals, according to a study published in the January/February 2010 issue of General Dentistry, the peer-reviewed clinical journal of the Academy of General Dentistry (AGD). Dentists typically request that their patients return every six months, which means that some people see their dentist more frequently than they see their physician. As a result, dentists may be the first to identify the symptoms of mouth breathing. And, because dentists understand the problems associated with mouth breathing, they can help prevent the adverse effects.   MORE HERE



Is articaine better local anesthetic for infiltrations?  
Articaine worked better than competing anesthetics in seven out of 10 randomized clinical trials of infiltration analyzed for a review presented at the recent American Association for Dental Research (AADR) meeting in Washington, DC.

"We have a number of solutions to choose from, and, for me, that's a daunting task," said Ryan Brandt, D.D.S., a University of Michigan endodontic resident. He said he'd found recommendations from some of dentistry's leading luminaries, but "these opinions don't necessarily agree with the evidence." On the other hand, lidocaine is still the most used for infiltrations in the U.S., he said. Articanine is sold as Septocaine by Septodent. There are reports that articaine use for nerve blocks may cause
paresthesia.

Sinusitis after Implants, Oral bacteria travel to womb, Drink tap water-avoid caries

More Mobile phones in India than Toothbrush or Toilets
Indians have "low level of awareness about the importance of oral health and hygiene" and nearly half of them do not use toothbrush and toothpaste, a survey said Monday, 12 April.

This was revealed by the Consumer Usage and Attitudes Survey conducted across the four geographic zones in India. The study conducted by research firm IMRB said only 51 percent of the people brush their teeth with a toothpaste and a toothbrush.

"Only 28 percent of the respondents brush their teeth twice a day and 34 percent believe that the current frequency of brushing once a day is sufficient," the survey said."Two out of three consumers have never visited a dentist."
The study also said that only 47 percent of total treatments received are by dentists. The rest prefer to rely on advice from chemists, general practitioners or self-treatment using home remedies.  LINK

According to a report the total mobile phone or wireless connections in the country, by the end of January 2010, was at 54.50 crore. It is estimated to be about 60% as on April 2010.   LINK

According to a UN report there are more mobile phones in India than toilets, LINK

Maxillary Sinusitis After Implant Placement, Yes it Happens
Implant Dentistry:,April 2010 - Volume 19 - Issue 2 - pp 115-121

The purpose of this study was to evaluate the prognosis and treatment of infection of the maxillary sinus associated with dental implants.

Methods: Oral and radiographic general clinical features of 2 patients who developed maxillary sinusitis after implant placement.
Results: The symptoms of maxillary sinusitis were improved by curettage through the lateral wall of the maxillary sinus, antibiotics, and sinus irrigation after 2 weeks of the operation.

Conclusion: It was concluded that acute maxillary sinusitis should be treated with a direct approach to the maxillary sinus via lateral wall opening, regular irrigation in hospital, and antibiotics.

Oral contraceptives in women adversely impact periodontal health
JOP Apr 2010
oral contraceptive (OC)  users, particularly smokers, showed a statistically significant increase in the prevalence of severe periodontitis. OC users had deeper probing depths and higher gingival index scores ≥2 and clinical attachment loss ≥5 mm than non-users (P <0.01). Patients on OCs had significantly higher numbers of cultures positive for Candida. Seven Candida species were isolated. Subgingival Candida was associated with P. gingivalis and P. intermedia in 82.9% and 85.4%, respectively, in patients taking OCs. A. actinomycetemcomitans was isolated in patients with moderate and severe periodontitis and was associated with subgingival P. gingivalis, P. intermedia and Candida.

Conclusions: OC use may increase the risk of severe periodontitis and seems to cause a selection of certain Candida species in periodontal pockets. OC users showed a higher prevalence of P. gingivalis, P. intermedia and A. actinomycetemcomitans compared to non-users. C. albicans, C. parapsilosis, C. krusei, C. tropicalis and C. glabrata were the species with the ability to survive in the conditions created by the sex hormones after 3 years.

Oral Bacteria Linked to Intrauterine Infections and Pre-Term Birth
Bacteria in the mouths of pregnant women can contribute to pre-term birth, according to researchers from Case Western Reserve University, Cleveland, Ohio, and Hathaway Brown School, Shaker Heights. The findings are published in the April 2010 issue of the journal Infection and Immunity.
Approximately 12.7% of births in the U.S. are pre-term deliveries, a rate that reflects a 36% increase over the last 25 years. Intrauterine infection is recognized as a main cause of pre-term birth as well as late miscarriage and still birth. The cause of intrauterine infections has long been attributed to bacteria ascending into the uterus from the lower genital tract, however, recent studies indicate such infections are caused not only by bacteria found in the vaginal tract, but also in the mouth.

 Caries, Gum Disease Found in Genes
Certain genetic variations may be linked to higher rates of tooth decay and aggressive periodontitis, according to two recently published papers by researchers at the University of Pittsburgh School of Dental Medicine and their collaborators.
Alexandre R. Vieira, D.D. S., Ph.D., senior author of both papers and an assistant professor of oral biology, and his colleagues at the School of Dental Medicine found that the rate of dental caries was influenced by individual variations, or polymorphisms, in a gene called beta defensin 1(DEFB1), which plays a key role in the first-line immune response against invading germs. The findings are available online in the Journal of Dental Research. MORE HERE

Toothpaste With Triclosan/copolymer Kills Harmful Germs, also read the next news below
The human mouth is home to an estimated 800 to 1,000 different kinds of bacteria. The warm and moist environment, along with hard tooth surfaces and soft tissues, prove to be optimal factors in boosting germ growth. Many of these bacteria are harmful and can form a film on teeth called "dental plaque," which causes cavities, gingivitis and eventually more severe kinds of gum.
Toothpaste that contains triclosan/copolymer is better than regular fluoride toothpastes at killing the kinds of bacteria that live in people's mouths, according to a study published in the January/February 2010 issue of General Dentistry, the peer-reviewed clinical journal of the Academy of General Dentistry (AGD).

Studies Show Antiseptic Chemical Triclosan Can Alter Hormones in Animals
April 13, 2010

With new research indicating that triclosan -- a chemical found in toothpaste and many other consumer products -- may disrupt the endocrine system and create bacteria that are resistant to antibiotics, the FDA is now looking at whether this substance is as safe as originally thought.

The agency's decision to review triclosan -- a substance it last studied in 1997, concluding at the time that it helped enhance toothpaste -- comes after repeated requests by Rep. Edward Markey (D-MA), chairman of the Energy and Commerce Committee's Subcommittee on Energy and the Environment.

Markey first approached the FDA with concerns about triclosan in January, and repeated his request for a review of the substance in letters sent to the FDA and the Environmental Protection Agency (EPA) earlier this month. He has also written to 13 major manufacturers of products containing triclosan -- including Colgate-Palmolive and Procter and Gamble -- urging them to voluntarily stop using triclosan.  MORE

Drinking Tap Water May Help You Avoid Dentist's Drill
The controlled addition of a fluoride compound to public water supplies is considered to be the most cost-effective way to prevent cavities and fight tooth decay, according to a study published in the January/February 2010 issue of General Dentistry, the Academy of General Dentistry's (AGD) peer-reviewed clinical journal.
Tooth decay affects children in the United States more than any other chronic infectious disease, according to the Centers for Disease Control and Prevention (CDC). The CDC states that tooth decay, if left untreated, can cause pain and infections that hinder eating, speaking, playing and learning. MORE

'Ugly Betty' Effect brings Ortho patients (Jassi jaisi koi Nahin)

Orthodontists call it the 'Ugly Betty effect', after the television show character who, despite working on a trendy fashion magazine, sports full 'train-track' braces.Adults now make up half of all patients in some UK clinics, according to the British Orthodontic Society  -  and despite the invisible, discreet options available, many choose to have traditional fixed braces.
'Thanks to Ugly Betty and film stars such as Tom Cruise having orthodontic treatment, there is no longer shame about being an adult with braces,' says Dr Neil Counihan of Elleven Orthodontics, in Central London, one of a number of private practices catering solely to the adult market. MORE

Use Chlorhexidine to improve bond strength
Want to make your restorations last longer? Add a dab of chlorhexidine to the preparation. That's the latest tip from some researchers presenting their findings at the recent American Association for Dental Research (AADR) meeting in Washington, DC. In fact, a few dental professors are so convinced it works they're already teaching it to their students as standard procedure.
And surprisingly, the main argument for adding this well-known disinfectant has nothing to do with bacteria.

"I think we're one of the first schools in the country to use it," said Peter Moon, Ph.D., director of the Virginia Commonwealth University Dental Biomaterials Laboratory. "I feel pretty strongly that it works."
Moon expects his review of the research to be published in a forthcoming issue of the Open Dentistry Journal. Another research group published a clinical trial last summer in Operative Dentistry (July-August 2009, Vol. 34:4, pp. 379-383). And two presentations on the topic at the AADR meeting generated some of the gathering's hottest buzz. MORE

The Effectiveness of a Preprocedural Mouthrinse Containing Cetylpyridinium Chloride (CPC)
JADA Apr 2010
During oral procedures, microorganisms from the oral cavity may contaminate nearby surfaces. The authors evaluated the efficacy of a commercial preprocedural mouthrinse containing 0.05 percent cetylpyridinium chloride (CPC) in reducing the levels and composition of viable bacteria in oral spatter. CPC and CHX were equally effective in lowering the levels of spatter bacteria and performed better than water and no rinsing.
Owing to its strong antibacterial effect and the fact that it has fewer side effects than CHX, a solution containing 0.05 percent CPC may be a good alternative to that containing 0.12 CHX as a preprocedural mouthrinse used to help decrease the level of contamination in spatter.

The Efficacy of Terminalia chebula (Haritaki) Rinse on Streptococcus mutans Count in Saliva and Its Effect on Salivary pH, Oral Health Prev Dent 8 (2010), No. 1  (01.04.2010)


Ten per cent of T. chebula extract was prepared. A purposive sample of 30 subjects was selected and randomly divided into extract and control groups. Baseline salivary sample was collected. The freshly prepared extract rinse and control were given to the respective groups. Distilled water was used as a negative control. Salivary samples were collected at 5 and 60 min after rinsing and were subjected to pH and microbiological analyses. An acceptability questionnaire was given to all of the participants. Statistical analysis was done using paired and unpaired t tests.
Results: There was a significant reduction in the S. mutans count at 5 and 60 min after rinsing the extract. Salivary pH remained alkaline for a period of 1 h after rinsing the extract. Results of the acceptability questionnaire indicated that the mouthrinse was acceptable to 80% of the subjects.
Conclusions: The results of the present study indicate that T. chebula may prove to be an effective anticaries mouthwash owing to its ability to increase salivary pH and inhibit S. mutans. This may also be a valuable public health intervention as it is economical and has multiple health benefits.

Effect of Finishing Instrumentation on the Marginal Integrity of Resin-based Composite Restorations
J of Est and Res dentisty feb 2010
The negative control specimens (course diamond) presented the largest gaps, whereas the positive control specimens (mechanically polished) generated the smallest gaps. No statistically significant difference was noted between the finishing diamonds and the positive control. The negative control exhibited significantly larger gaps when compared with the other finishing instruments. Intermediate results were observed for cross-cut, straight-cut, and spiral-cut laminated burs. Fine, extra-fine and ultra-fine finishing diamonds generated smaller gaps compared with laminated burs, but the differences were not always statistically significant.

Conclusion: Fine, extra-fine and ultra-fine finishing diamonds used to finish composite restorations generated better marginal integrity when compared with carbides and regular-grit diamonds. When finishing composite restorations, finishing diamond burs result in better composite margins than carbide laminated burs.

PROTEINS MAY PREDICT ORAL CANCER
The presence of certain proteins in oral premalignant lesions (OPLs) may predict oral cancer development, according to a study published online Feb. 22 in the journal Cancer.

Small integrin-binding ligand N-linked glycoproteins (SIBLINGs) are a family of five proteins that help mineralize bone but also can spread cancer. SIBLINGs have been found in cancers including breast, lung, colon and prostate.

Researchers evaluated 60 archival surgical biopsy specimens of dysplastic OPLs by means of immunohistochemistry for expression of BSP, DSPP and OPN and correlated the specimens with local transformation to oral squamous cell carcinomas at sites adjacent to the surgically removed dysplastic OPLs.

They found that 87 percent of the biopsy specimens were positive for at least one SIBLING, which they discovered could be good or bad, depending on the protein. For instance, they found that DSPP increased the risk of developing oral cancer fourfold, and BSP significantly decreased this risk.

"The proteins could be used as biomarkers to predict [the potential of a lesion to become cancerous]," said Dr. Ogbureke. "That is very significant, because we would then be in a position to modify treatment for the individual patient’s need in the near future." JADA apr 2010

Nano-Bio-Chip Effective To Detect Premalignancies In Oral Cancer ?
Journal Cancer Prevention Research The test that uses Rice's diagnostic nano-bio-chip was found to be 97 percent "sensitive" and 93 percent specific in detecting which patients had malignant or premalignant lesions, results that compared well with traditional tests.
"One of the key discoveries in this paper is to show that the miniaturized, noninvasive approach produces about the same result as the pathologists do," said John McDevitt, the Brown-Wiess Professor of Chemistry and Bioengineering at Rice. His lab developed the novel nano-bio-chip technology at the university's BioScience Research Collaborative.

Oral cancer afflicts more than 300,000 people a year, including 35,000 in the United States alone. The five-year survival rate is 60 percent, but if cancer is detected early, that rate rises to 90 percent.  MORE

Factors affecting soft tissue level around anterior maxillary single-tooth implants
Clinical Oral Implants Research Apr 2010
The majority of the implants (75%) replaced the upper central incisors. The facial mucosal margin of the implant was 0.5±0.9 mm more apical than that of the contralateral tooth. Half or more of papilla fill was observed in 89% of the samples. More apical level of the facial mucosal margin at the implant sites was significantly influenced by many factors including a thin peri-implant biotype, a proclined implant fixture angle, more apical level of the facial bone crest, increased distance from the contact point to the bone crest, contact point to the platform, and contact point to implant bone. A thin biotype was the most significant factor in determining the facial marginal mucosal level. Increased distance from the contact point to the bone crest was the only factor significantly associated with less papilla fill.

Conclusions: The papilla level around single-tooth implants in the anterior maxilla was mainly influenced by the interproximal bone crest level of the adjacent tooth. Facial marginal mucosal level, on the other hand, was affected by multiple factors including the peri-implant biotype, the facial bone crest level, the implant fixture angle, the interproximal bone crest level, the depth of implant platform, and the level of first bone to implant contact.

Association Between Obesity, Flow Rate of Whole Saliva, and Dental Caries in Adolescents
Obesity Mar 2010
Of obese patients, 17 subjects had visible plaque index % >25 and 21 had bleeding on probing (BOP)% >25, both compared to only 5 subjects of the normal weight with P values of 0.005 and <0.001, respectively. In a multivariate logistic regression model BMI-sds was significantly associated with the flow rate of stimulated whole saliva less than the median value 1.5 ml/min (P < 0.001; odds ratio (OR) 1.36) as well as with DS (DS >0) (P = 0.002; OR 1.31) and the associations were not found to be confounded by any of the studied variables. The results indicate that childhood obesity is associated with reduced flow rate of stimulated whole saliva and dental caries and further strengthens obesity's negative effect on children's oral health.

Bacterial Leakage Of Provisional Restorative Materials Used In Endodontics
Quin Int, April 2010, Volume 41 , Issue 4
Aim was to test the bacterial sealing ability of commonly used provisional endodontic restorative materials. Method and Materials: This study investigated Cavit (3M ESPE), Ketac (3M ESPE), DuoTemp (Coltène/Whaledent), and a combination technique using Ketac and Cavit. One hundred molars were randomly selected and then mounted in an apparatus that isolated the crown portion of the tooth. Provisional restorative materials were placed in an open access following manufacturer guidelines. Streptococcus mutans was applied to the samples, and results were tabulated over the course of 4 weeks. Results: Cavit and DuoTemp performed the best, and Ketac performed the worst. After 14 days, however, all materials leaked in over half of the samples. Conclusion: No material can be recommended as superior in providing a reliable seal after 14 days.

Woman arrested for using gradma's credit card for dental work ( it happens only in USA ! )
A 42-year-old Tempe, AZ, USA woman who is accused of stealing her grandmother’s credit card and using it to get $2,300 in dental work done was arrested Monday on suspicion of theft and identity theft.

Jennifer Brice, who admitted to police she used the credit card without her grandmother’s permission, was using her grandmother’s car when she found the card inside of it, according to Mesa police.

Brice was able to rack up the charges on the card after pretending to call her grandmother from the dentist’s office to ask if she was allowed to use it, according to police.
Brice’s grandmother, who had forgotten about the credit card, was reimbursed.

Dental practice hit by online thieves
Computer criminals stole more than $200,000 ( Rs 92 Lakh )out of the online bank accounts of a Missouri dental practice on March 22, according to an article on krebsonsecurity.com, a blog written by Brian Krebs, a former Washington Post reporter who now covers online scams, data breaches, and related stories.

Dentists working at Smile Zone, a pediatric dental practice in Springfield, MO, told Krebs that the unidentified thieves sent at least $205,000 of the practice's money to nearly a dozen individuals around the U.S.

The money was allegedly taken in 11 different transfers, including three large wires. The attack was carried out with the help of "money mules" -- willing or unwitting individuals hired through Internet-based work-at-home job schemes who help the attackers launder the stolen money, according to Krebs.

Eric Hudkins, Smile Zone office manager, told Krebs that he had contacted the FBI but was told the agency won't open a case on a theft like this unless it is more than $500,000 in losses. The case will instead be included with a group of similar investigations being handled by an FBI task force in Omaha, NE. MORE

Efficacy of Amoxicillin and Metronidazole Combination for the Management of Generalized Aggressive Periodontitis - JOP March 2010
Twenty-eight patients were randomly included. The test group (N = 12) received amoxicillin- metronidazole combination and scaling-root planing; the control group (N = 16) received scaling-root planing alone.All clinical parameters improved significantly compared to baseline (P <0.05) in both groups. There was a statistically significant reduction of pockets and clinical attachment gain in the combined group compared to the control group (P <0.05). Total counts of bacteria also decreased significantly at 3 and 6 months in both groups (P <0.05). Treponema denticola and Tannerella forsythia were the most prevalent bacteria throughout the study. Treponema denticola showed a continuous decrease over 6 months in the test group while no change was seen in the control group beyond 3 months. Porphyromonas gingivalis decreased significantly at 3 months (P <0.05) while Tannerella forsythia was the only pathogen decreased below detection limits by the combination therapy with a significant difference compared to the control group (P <0.05).

Conclusion: The results from this study suggest that combined amoxicillin and metronidazole use as an adjunct to scaling and root planing leads to a better clinical healing compared to the mechanical treatment alone. The polypharmaceutical approach used results in a significant and substantial decrease in Tannerella forsythia and prevents its recolonization for 6 months suggesting that Tannerella forsythia may determine the long-term stability of periodontal treatment outcome.

Silver bullet for Dental Caries
"Why drill when the infection is gone?" asks Dr. Steven Duffin, D.D.S., who frequently uses silver diamine fluoride on an off-label basis in his general practice in Oregon. He calls it the "most effective agent" he's seen in 30 years to arrest caries.

In addition, he believes that SDF's potent antimicrobial effectiveness is also long-lasting and pervasive. "I have also noticed that kids who are treated with SDF do not get new cavities three-plus years out," he said in an interview. "It seems to have a protective effect beyond the treated lesion."

But SDF has yet to win FDA clearance. And it is plagued by a well-known and unsightly drawback: It leaves behind a "black crust" on caries lesions. MORE HERE

A Systematic Review of Marginal Bone Loss Around Implants Retaining or Supporting Overdentures
Forty-six articles were included in the analyses; data extraction and meta-analysis were able to be conducted on eight studies. Data regarding maxillary overdentures could not be analyzed statistically. Bone loss around mandibular implants did not seem to be influenced by implant system or attachment design (bar, ball, magnet, and other types) in the first year, from 1 to ≤ 5 years, and even after 5 years (P > .05). Meta-analysis could not detect differences in implant systems or attachment types (P > .05). Conclusions: Based upon a systematic review and meta-analysis of the literature that identified a total of 4,200 implants from 13 manufacturers, there was no difference in marginal bone loss around implants retaining/supporting mandibular overdentures relative to implant type or attachment designs.
