Shedding Some Light on LEDS

by John C Comisi, DDS, MAGD

LED lights are a great asset to today’s dental practice. LEDs do not require fans for cooling, so they are smaller, quieter, and more convenient than halogen lights. However, clinicians should be aware of potential challenges posed by these high intensity curing lights.

A study published in the Journal of Dentistry in 2017 surveyed 1313 dentists in Norway regarding safety awareness and their knowledge of the practical use and technical features of their curing lights. Over 55.8% of those surveyed respond to the survey. The results showed that the average length of light cure of a typical layer of composite was 27 seconds. Almost one-third of respondents used inadequate eye protection against blue light, and 78.3% of the respondents were unaware of the irradiance value of their curing lights. Interestingly, regular maintenance was not performed by many dentists in this group.

The implications of this article are troubling for two reasons:

1. The wavelength of light emitted from LEDs can cause irreversible eye damage. 
2. Unlike halogen lights which “blow out,” it is harder to tell when an LED light no longer provides sufficient energy to polymerize the resins in restorative materials.

Proper eye protection is absolutely essential for both the dental team and the patient. Safety is always our first concern.

The routine use of a digital radiometer with a numerical readout is absolutely necessary to ensure sufficient irradiance energy to fully cure resin-based materials. Otherwise, practitioners run the risk of under-curing resin-based materials. Unpolymerized resins can result in what I like to call a “Tootsie Pop” restoration, i.e., crunchy on the outside and soft on the inside, which can lead to patient sensitivity, pulpal necrosis, and restoration failure.

The Social Dentist Tip #4: Stay Engaged and Step It Up

Dr. Ryan McCall grew his Indiana-based dental practice by engaging new and existing patients through Facebook, Instagram, Snapchat and Twitter. In this series, The Social Dentist, Dr. McCall offers tips on how to market your dental practice using social media.

Stay Engaged
As an independent practice owner, I strive to differentiate my services from large corporate practices by actively engaging patients on social media. I often run ads targeting fans of our pages and their friends.

Sharing posts on social media has become the new word of mouth. Many of our referrals come through social media, and patients who read good reviews about us online are always eager to start treatment.   

Step It Up
Social media posts (i.e., content you publish), likes (from patients, prospective patients and others), and tags are a good start, but you’ll eventually have to step up your media efforts to maintain a steady flow of patients and referrals.  Consider adding email marketing and targeted ad campaigns to your media mix. Facebook ads allow you to target specific demographics, and they have a pixel tracking function that shows which ads drive traffic to your website. We use the Facebook pixel tracking tool every day to track new leads, and then I follow through with great content.

Embracing a Preventative Plan for Pediatric Patients

By Jarod W. Johnson, DDS, ABPD

Dental caries is the most common chronic disease in children. It is more common than obesity, asthma, and diabetes.1 It is estimated that one in five children will experience tooth decay in a primary tooth between ages two and five, and three in five will experience tooth decay between age twelve and nineteen.2 If left untreated, tooth decay can lead to pain, swelling, infection, and in rare occasions, hospitalization or death. Because infants and toddlers are often uncooperative, treating young children can be challenging for dental practitioners.  

Prevention Starts with a Dental Home
The AAPD, AAP, and ADA all recommend establishing a dental home by age one or when the first tooth erupts.3  This provides parents and caregivers with guidance and information regarding the health and wellbeing of the child’s teeth. In addition to a clinical assessment and necessary diagnostic tests, preventive guidance should include counseling on oral hygiene, diet, injury prevention, non-nutritive habits (pacifier or digit habits), and speech and language development.4 A complete assessment allows practitioners to establish a patient’s caries risk and make a referral to a pediatric dentist, if necessary.
Completing a caries risk assessment is important because dental caries is a multifactorial disease. Parents must be educated and motivated to change habits, and it is unrealistic to assume this can be done after one visit. The assessment allows practitioners to establish a preventive plan for high caries risk patients with the use of fluoride treatments, such as Embrace Varnish, to release calcium, phosphate and fluoride, and potentially delay expensive or high risk procedures, such as sedation.

Embrace Varnish as a Component of Active Surveillance and a Preventative Plan
The application of fluoride varnish has been shown to reduce primary tooth decay by over one third when applied professionally,5 and therefore, the prevention plan for high risk pediatric patients should include quarterly applications of fluoride varnish.

The application of Embrace Fluoride Varnish, which contains 5% sodium fluoride, Xylitol, and bioavailable calcium and phosphate, can help treat superficial, non-carious enamel lesions (white spots) and provide minerals known to be beneficial for tooth structure. Calcium and phosphate are the building blocks of teeth, and the addition of these minerals provides benefits to patients who may be deficient in these minerals, such as patients with xerostomia or poor dietary habits.

Embrace Fluoride Varnish can play a key role in the active surveillance of a child’s cavities. Applications every three months in high risk children with sub-acute needs may help delay the necessity for sedation for dental treatment and provide practitioners with the opportunity to improve oral hygiene and correct dietary habits over time. More frequent visits can also help desensitize children to the office experience and detect problems in the early stages.

At each visit the child should have a clinical exam and necessary diagnostic testing; a child’s risk for developing cavities should be assessed. While we can’t always control what patients do at home, we can utilize the abilities of a prevention program. Embrace Varnish applied at the appropriate frequency, to help improve oral conditions, can create an environment that helps reduce the incidence of dental decay.

Why Choose Embrace Varnish?
As clinicians we must choose products that maximize efficacy for our patients. In vitro studies have shown that Embrace Varnish has ten times more cumulative fluoride release than the leading brand during the 4-hour treatment period.6 High fluoride release in varnishes helps provide conditions that are favorable for strong, healthy, more acid-resistant teeth. Embrace has a proprietary resin carrier with Xylitol-coated calcium and phosphate. In the mouth, saliva dissolves the xylitol and releases significant amounts of calcium and phosphate ions, which are key components of enamel.7

Teeth are made of calcium and phosphate in the form of hydroxyapatite. The presence of fluoride precipitates fluorapatite onto the enamel surface. Fluorapatite is more resistant to the acidic environment than hydroxyapatite.8 The ability of a product to deliver calcium, phosphate and fluoride is important to consider when selecting an in-office fluoride treatment. The high concentration of calcium, phosphate and fluoride release makes Embrace Varnish appealing for use in high caries risk patients and those with compromised tooth structure.
