Ultrasonic Scaling Side Effects

Ultrasonic Scaling Side Effects

Although ultrasound is used routinely on patients, there are few hazards associated with its use. The ultrasonic scaler may result in potential hazards to both the patient and the clinical operator of the equipment. The ultrasonic scaler is a useful instrument in the field of periodontology, but considerations need to be made when utilizing it in the clinical situation

Thermal effects on pulp

A temperature rise in the tooth caused by heating can cause damage to the pulp and dentine. Heating of the [pulp should be avoided as it can cause irreversible pulpitis. The use of ultrasonic scaler will produce an increase in temperature, and this heat may be due to friction between scaler and tooth. The studies conclude that powered scaling should not be considered without irrigation and the flow rate should be in the region of at least 20-30 ml\min.

Thermal effects on periodontal tissues

Early workers demonstrated that ultrasonic scaling causes no injury to the periodontal membrane, alveolar bone or the gingiva. Further histological examination of tissues immediately after ultrasonic scaling showed superficial tissue coagulation. It was found that curettage with ultrasonic instruments resulted in quicker healing


Vibrating a wire at an ultrasonic frequency will potentially damage erythrocytes, leucocytes, platelets. Platelets are sensitive to shear stresses, and such forces are produced by the occurrence of acoustic micro streaming around an ultrasonically oscillating wire. Pulpal thrombosis from dental ultrasonic scaling is still a possibility. If the formation of thrombus occurs in vessels supplying the tooth pulp, it could result in tooth death during ultrasonic scaling

Vibration to operator

It is known that the large amplitudes produced by pneumatic drills causes ‘white finger’, a disruption in the blood flow to the fingers, caused by vibrations passed from the drill through to the hand. Some persons experienced symptoms like tingling, numbness and reduced manipulative dexterity although none of the persons had neurological symptoms in their non-dominant hand. Long time exposure to ultrasonic scalers had a high frequency of neurological symptoms that was especially prevalent in their dominant hand. However it was concluded that these neurological symptoms were not due to a vibrating hand piece since the exposed second and unexposed fifth fingers were similarly affected. It was found that the vibrations could produce a reduction in strength and tactile sensitivity and performance due to disruption of blood and nerve supplies to the fingers.


When using the ultrasonic scaler a fine aerosol is produced, this may spread pathogenic microorganisms. This aerosol production could be hazardous to health. Aerosol containing micro9organisms can be reduced by 99% during ultrasonic scaling, if air is blown down from the ceilings and through vents in the wall base which are then filtered to re- enter the cycle. Aerosol can be greatly reduced if t6he operator uses a high filtering properly fitted face mask. The use of a pre procedural rinse using an antiseptic mouth wash reduces the microbial content of aerosols during ultrasonic scaling. If ultrasonic scalers are used subgingivally, the aerosol produced will contain blood contamination.


Ultrasonic scalers may be a potential hazard to the auditory system of both clinicians and patients. Damage to operator hearing is possible through the ultrasonic scaler. FOR the patient damage can occur through the transmission of ultrasound through tooth contact to the inner ear via the bones of the skull. This later hazard is a possibility during scaling of the molar teeth. Tinnitus is an early sign of hearing loss and may occur following ultrasonic scaling. A small number of dentists have experienced tinnitus or numbness of the ears after the prolonged use of ultrasonic scalers, which indicates a small potential risk to hearing.

Cardiac pacemakers

The proximity of magnetic, electrical or electromagnetic fields can affect the operator of cardiac pace makers. Recent work investigating the magnetostrictive scaler stated that interference can be caused if the pacemaker pacing lead comes within 37.5 cm of the scaler.

Vitamin K Functions and Sources & Deficiency Symptoms

Vitamin K is a fat soluble vitamin, so your body stores it in fat tissue and the liver. Three forms of vitamin K are vitamin K1, vitamin K2 and vitamin K3. Vitamin K is necessary for blood clotting process. In the name vitamin K, k is the short form for the german word “koagulation”. Gut microbes can synthesize the vitamin K

What are the functions of vitamin K?

  • Vitamin K is an essential vitamin required for protein modification and blood clotting
  • Protects you from significant blood loss when you get injured
  • Helps in bone formation. The creation of mineral dense, strong bones results from an interplay between the function of vitamin K and vitamin D. The bone making cells called osteoblasts moves Ca in response to a hormone called osteocalcin. This hormone is regulated by vitamin D.
  • Vitamin K also involves in the prevention of the bone loss by inhibiting the production of osteoclasts the cells which break down the bone
  • Investigated as a critical nutrient for protecting cells that line blood vessels, including both veins and arteries.
  • It helps cells to communicate with each other
  • Vitamin K helps to prevent hardening of the arteries, which is a common factor in coronary artery disease and heart failure

How much amount is required?

Recommended dietary allowance of vitamin K is

0-6 months                                                                 2mcg

7-12 months                                                                 2.5mcg

1-3 years                                                                         30mcg

4-8 years                                                                         55mcg

9-13 years                                                                        60mcg

14-18 years                                                                  75mcg

19 years and older men                                               120mcg

19 years and older women                                         90mcg

Pregnant and breast feedi9ng women 19-50yrs     90mcg

Pregnant and breast feeding women below 19yrs 75mcg

vitamin-k-foodsHow can I get vitamin k?

The vitamin K sources are

  • Green leafy vegetables-spinach, mustard greens, turnip greens, beet greens
  • Spring onions, lettuce, cabbage, cauliflower, broccoli
  • Cucumber, soybeans, asparagus
  • Dried coriander
  • Olive oil, canola oil
  • Dried fruits-blue berries, pears, peaches, figs
  • Beef liver
  • Chili powder

Who are at risk for vitamin K deficiency?

It is rare to have a vitamin K deficiency. That’s because in addition to being found in green leafy food, the bacteria in your intestine can make vitamin K

  • Newborns are at greater risk for vitamin k deficiency because babies are born without any bacteria in their intestines and do not get enough vitamin K from breast milk to tide them over until their bodies are able to make it
  • Vitamin K deficiency also seen in premature babies or those where mother had to take seizure medication during pregnancy
  • Dietary deficiency is extremely rare unless the intestine was heavily damaged, resulting in mal absorption of molecule
  • Have a disease that affects absorption in the gut, such as crohn’s disease or active celiac disease
  • Taking broad spectrum antibiotics can reduce vitamin K production in the gut by nearly 74% in people compared with those not taking these antibiotics
  • Taking drugs that interacts with vitamin K absorption
  • Severely malnourished
  • Over consumption of alcohol
  • Those with serious burns
  • Taking blood thinners
  • Those with liver diseases
  • Diet low in vitamin K
  • Those with chronic kidney disease

What are the symptoms of vitamin K deficiency?

  • Affects the blood clotting. Bleeding within the digestive tract, gum bleeding and heavy menstrual bleeding
  • Bruising, petechiae, hematomas
  • When there is a deficiency of vitamin K , osteocalcin does not bind CA. This means that Ca cannot bind to the bone matrix. Bones become porous due to lack of Ca. Ca is then also free to travel in the blood, and eventually gets deposited in the arteries. This cause a hardening of arteries known as atherosclerosis.
  • In infants, it can cause some birth defects such as underdeveloped face, nose, bones, fingers
  • Cartilage calcification
  • Uncontrolled bleeding at surgical or puncture sites
  • Low levels of vitamin K have been found in those with osteoporosis
  • Bleeding in brain in newborns

How to overcome vitamin K deficiency?

  • Avoid taking more antibiotics without doctor consultation
  • Take fresh green leafy vegetables
  • Underlying diseases should be treated
  • Mothers on seizure medications are often given oral vitamin K for 2 weeks before delivery
  • In some countries vitamin K injection is given to newborn babies to prevent bleeding in brain
  • Oral vitamin K supplements

Finger Toothbrush For Kids? Benefits & How to Use

What is Finger Toothbrush?

A finger toothbrush is a small set of soft cleaning bristles worn on the fingertip. Most finger toothbrush bristles are made of the pliable and easy to clean material silicone. Finger toothbrushes are often worn by people who are brushing teeth that are not their own to achieve maximum control and avoid causing tooth or gum injury.

finger-tooth brushThe finger toothbrush is fitted onto the finger of the user so the person is able to gently clean the teeth and massage the gumline at angles that no rigid toothbrush would be able to achieve. Technicians in the health care and veterinary industry often use disposable finger toothbrushes to clean effectively the teeth of their patients without spreading infections.

What are the Benefits of Silicone Finger Toothbrushes for Children?

Silicone finger toothbrush is a toothbrush that delivers the unique benefits of soft silicone. This toothbrush is made up of safe and clean nontoxic silicone, contains silver nano and the negative ions released from bristles inhibit the bacteria, viruses and fungi. The majority of finger toothbrushes are simply flexible silicone sheaths that are slid on to the end of the index finger and stop before the second joint. A brush must fit snugly onto the fingertip to make sure it will not come off during use and become a choking hazard

  • Helps teething by massaging sore gums
  • Encourages your child to get used to their feeling of brushing
  • Inhibits the growth of bacteria and fungi
  • Decrease the risk of bacterial and fungal infections
  • Massages baby’s gums during teething
  • Softer than nylon bristle
  • Protects natural surface of the teeth from abrasion and the gums from recession
  • Massages young children delicate gums while protecting the enamel layer on the surface of their teeth, strengthening the gums
  • Provides interest in child to brush
  • Silicone does not damage the skin rather it tends to develop a natural affinity with skin cells
  • Ability to eliminate foreign substances and clean the scales
  • Can be sterilized in boiling water or sterilizer
  • Relieves sensitivity of teeth and tender gums
  • A finger toothbrush made from thicker silicone protects the finger of the wearer from those who have a tendency to bight down during brushing
  • Gives parents a more sensitive touch on their child’s tender gums
  • Allows better access in hard to reach areas
  • Very convenient to use
  • hygienic and hypo allergic
  • nontoxic and nitrosamine free
  • free of BPA and PVC
  • some varieties of finger toothbrushes come with carrying cases and ultraviolet sensitizing lights to kill bacteria during storage

How to Use Finger Toothbrush?

  • Sterilize before use by immersing in boiling water 2-5 minutes.
  • Wash your hands. Place finger toothbrush on index finger. Make sure finger fit5s snugly inside once put on
  • Place small amount of tooth paste on bristles
  • Use small circular motion to gently brush your baby’s tiny teeth and gums
  • After use, wash in hot water with mild soap and rinse thoroughly with clear water
  • Brush twice a day
  • To prevent possible choking hazards inspect before and after each use and replace immediately if any signs of excessive wear appear. This toothbrush is not a toy so don’t allow your child to play with it
  • To be used by adults only
  • Wash before initial use
  • Some finger toothbrush bristles are built into latex gloves so the brush stays on and the wearer and individual receiving the cleaning are both protected from contamination. Once the finger toothbrush is in place, the user simply applies gentle pressure with the bristles to clean the teeth and gums using a tight circular motion. This type of finger toothbrush is commonly used in healthcare department.
