(Press-News.org) Dental anxiety can be so extreme for some patients that a simple cotton swab on the gums makes them flinch. And others, fearful of pain, simply avoid seeing the dentist, according to a new study by Case Western Reserve University dental researchers on when and how to use sedatives during dental procedures.
As a result, dentistry is responding with sedation techniques to make fearful and anxious patients more comfortable.
For a master's thesis in endodontics, Madhavi Setty, DDS, MSD, set out to understand how dental specialties like endodontics for root canals, periodontics to treat gum disease and oral surgery for extractions and corrective surgeries used moderate sedations in their different specialties.
Moderate sedation allows the patient to remain conscious by suppressing the brain's responses to pain and stress while still being able to communicate with the dentist. The three dental specialties reported using moderate sedation in conjunction with local anesthesia in order to control anxiety and pain.
Setty's findings were reported in the Journal of Endodontics article: "An Analysis of Moderate Sedation Protocols Used in Dental Specialty Programs: A Retrospective Observational Study."
Thomas A. Montagnese, DDS, MS, assistant professor in the Department of Endodontic at Case Western Reserve School of Dental Medicine, is the study's corresponding author and Setty's thesis advisor. Other contributing authors are: Anita Aminoshariae, DDS, MS, assistant professor, and Andre Mickel, DDS, MSD, professor and chair of the endodontics department, and Dale Baur, DDS, MD, professor and chair of CWRU's oral and maxillofacial surgery department. The faculty members were on Setty's thesis committee.
The findings came from a retrospective study of 84 patients, who received care and moderate sedation during a visit to a Case Western Reserve's dental clinics in endodontics, periodontics and oral surgery graduate programs between 2010 and 2012.
The study also looked at each patient's age, sex and existing medical conditions, like high blood pressure, heart trouble or diabetes, that require consideration during treatments.
Patients ranged in age from age 8 to 88; their average age was 45. Most (63 percent) were women.
Researchers found moderate sedation was primarily used to calm anxiety in more than half of the patients (54 percent), followed by fear of needles (15 percent), local anesthesia failures (15 percent) and severe gag reflex and claustrophobia from the rubber dam (both 8 percent).
While moderate sedation helps to calm anxious patients, the catch is that not all endodontists are qualified to administer it. The procedure is not generally taught in most graduate endodontic programs, Montagnese said.
The Department of Endodontics at Case Western Reserve introduced training for moderate sedation into its curriculum last year. The study provides a guideline to when its best to use moderate sedation, Montagnese said.
Montagnese explained that endodontic training follows rules and regulations set by the Ohio State Dental Board, and the American Dental Association Guidelines for the Use of General Anesthesia and Sedation by Dentist Guidelines to meet the requirements necessary to qualify for certification to administer moderate sedation.
The ability to use moderate sedation allows endodontists more options for patient care—especially for those anxious and fearful of pain.

The once-powerful Category 5 Typhoon Vongfong has fortunately weakened to a barely Category 1 typhoon as it approaches the big islands of Japan. NASA-NOAA's Suomi NPP satellite and NASA's Aqua satellite passed over Vongfong on Oct. 11 and noticed the heaviest precipitation was north of the center.
NASA-NOAA's Suomi NPP satellite passed over Vongfong on Oct. 11 at 17:23 UTC (1:23 p.m. EDT) and captured an infrared image of the storm from the VIIRS instrument. The VIIRS instrument showed that the strongest thunderstorms that stretched highest in the atmosphere were in the ...
NASA's Aqua satellite passed over Cyclone Hudhud as it was nearing east-central India's coastline on Oct. 11.
The Atmospheric Infrared Sounder or AIRS instrument aboard Aqua captured infrared data on the storm on Oct. 11 at 07:23 UTC (3:23 a.m. EDT) that showed cloud top temperatures had dropped, indicating stronger uplift and stronger thunderstorms. That's an indication that the storm has strengthened in the last day.
The Joint Typhoon Warning Center noted that animated infrared satellite imagery shows the eye feature has become cloud filled while the overall structure ...

Tropical Storm Gonzalo formed quickly on Oct. 12 just east of the Leeward Islands, triggering tropical storm warnings for many islands. NOAA's GOES-East satellite captured an image of the newborn storm on Sunday, Oct. 12, and Tropical Storm Fay northeast of Bermuda.
The GOES East satellite is a geostationary satellite managed by NOAA. At NASA's Goddard Space Flight Center in Greenbelt, Maryland the NASA/NOAA GOES Project creates images and animations and today's visible image, taken at 2:45 p.m. EDT showed a smaller Gonzalvo east of the Leeward Islands while Fay was ...
The mutations were familiar, but the patients' conditions seemed baffling at first. A team lead by Rockefeller University researchers had linked variations in an immune gene to rare bacterial infections. Shortly afterward, Chinese scientists told them of three children in that country with mutated versions of the same gene. However, the Chinese children had no history of the severe bacterial infections. Instead, they had seizures and unusual calcium deposits deep in their brains.
This discrepancy led to the discovery of an immune protein with paradoxical roles: It both ...
High-resolution cryo-electron microscopy has now revealed in unprecedented detail the structural changes in the bacterial ribosome which results in resistance to the antibiotic erythromycin.
Multiresistant bacterial pathogens that are insensitive to virtually all available antibiotics are one of the major public-health challenges of our time. The question of how resistance to various antibiotics develops is the focus of research being carried out by Ludwig-Maximilians-Universitaet (LMU) in Munich biochemist Daniel Wilson and his colleagues. As they report in the journal ...
Scientists from Queen Mary University of London (QMUL) and UCL (University College London) have identified what they believe could be a cause of pre-term premature rupture of the fetal membrane (PPROM), which accounts for 40 per cent of pre-term births, and is the main reason for infant death world-wide.
The researchers, whose work was funded by the charity Wellbeing of Women, used bioengineering techniques to test the effect of repetitive stretch on tissues of the amniotic membrane which surrounds and protects the baby prior to birth.
They found that stretching of the ...
New York | Heidelberg, 13 October 2014 Increasing reliance on renewable energies is the way to achieve greater CO2 emission sustainability and energy independence. As such energies are yet only available intermittently and energy cannot be stored easily, most countries aim to combine several energy sources. In a new study in EPJ Plus, French scientists have come up with an open source simulation method to calculate the actual cost of relying on a combination of electricity sources. Bernard Bonin from the Atomic Energy Research Centre CEA Saclay, France, and colleagues demonstrate ...
Scientists from Nanyang Technological University (NTU Singapore) have developed a new battery that can be recharged up to 70 per cent in only 2 minutes. The battery will also have a longer lifespan of over 20 years.
Expected to be the next big thing in battery technology, this breakthrough has a wide-ranging impact on many industries, especially for electric vehicles which are currently inhibited by long recharge times of over 4 hours and the limited lifespan of batteries.
This next generation of lithium-ion batteries will enable electric vehicles to charge 20 times ...
In the context of an aging population, the number of cases of people with multimorbidity, or multiple health conditions, is increasing, creating significant healthcare challenges. Now, the first comprehensive systematic review in this field has found higher levels of multimorbidity in women. Equally as importantly, it has revealed the poor quality of evidence on this increasingly critical area of healthcare.
The review's main author, Professor Jose M Valderas, NIHR Clinician Scientist of the University of Exeter Medical School, is calling for better quality research to ...
