 1. How are anesthetics useful in endodontic therapy?

Anesthetics are used in endodontic therapy for elimination of pain while treating vital teeth. It blocks the transmission of nerve impulses and the therapy can be carried out with patient comfort.

2. Why is anesthesia not indicated for all endodontic therapies?

Anesthetics are not used when the treatment planned is a painless procedure such as cleaning and shaping of a necrotic canal or filling the canal. Also in case of a necrotic tooth, ‘cavity test’ is performed to find the origin of the lesion, whether endodontic or periodontal. So anesthesia in such cases will mask the actual response of the patient leading to a wrong diagnosis.

3. What are the precautions taken while injecting the mucosa overlying the alveolar abscess?

When the mucosa overlying the abscess in infiltrated, the needle should not penetrate the purulent collection. It should be injected tangentially to the mucosa so that it is visible through the transparency of the tissues. Alternatively, Ring anesthesia or nerve block is given.

4. How is the usage of rubber dam advantageous in endo practice?

The usage of rubber dam protects the ingestion or aspiration of instruments, irrigating solutions or small fragments. It gives an opportunity to work in a clean surgical field, retraction and protection of soft tissues is achieved, provides better visibility, prevents transmission of infection from patients’ saliva to the operator, creates a comfortable atmosphere for the operator and comfort feeling for the patients.

5. How are lower canine and first premolar effectively anesthetised?

Lower canine and first premolar are effectively anesthetized at the level of the mental foramen by a mental nerve block. The advantage is that it acts sooner and anesthesia of tongue is avoided.


6. Why should mental nerve block be given carefully?

Care should be taken not to injure the mental nerve with the point of the needle. The needle should not be introduced into the mental foramen also.

7. What anesthetic procedure do extraction / surgery in the anterior palate require?

The soft tissues of the anterior palate are innervated by the anterior palatine nerve emerging through the incisive foramen. This nerve is blocked by injecting the anesthetic next to the incisive papilla, under pressure. The procedure is quite painful.

8. When is the anterior palatine nerve blocked to achieve anesthesia?

The posterior two thirds of the palate is innervated by the anterior palatine nerve that emerges from the greater palatine foramen between the second and the third molar. The nerve is anesthetized for any surgical procedure in the soft tissues of the hard palate from the tuberosity to the region of canine or from the midline of the palate to the gingival margin by injecting near the point of emergence of the nerve from the foramen.

Advanced Dental Technology For Pain Free Dental Care
New advancements in dental technology in the last decade have changed the way in which dentists can administer efficient and pain free dental care. So, if you are one of the many patients who avoid making appointments with your dentist because of your intense fear of procedures, there’s no need to jeopardize your dental health any longer.

Some of the most effective recent developments in dentistry include non-invasive laser dentistry, drill-less air abrasion and single visit CEREC restoration. These breakthrough techniques are having a remarkable impact on dentistry, allowing dentists to perform a variety of dental procedures more efficiently, more precisely and more comfortably.

Restore Damaged Teeth in One Visit with CEREC

CEREC, or Chairside Economical Restoration of Esthetic Ceramics, is a new and innovative dental instrument that is revolutionizing the way in which dentists can efficiently restore damaged and decayed teeth. While most dental restorations require multiple appointments with multiple painful injections, CEREC can complete your tooth restoration in just one visit, eliminating the need for impressions and additional injections with the seating of your new crown.

CEREC restoration is metal-free, which means no more unsightly silver fillings; and the high-grade ceramic material is compatible with the oral tissue found in your mouth. CEREC’s precision 3-D technology allows dentists to create a customized crown that perfectly fits your teeth and is completely biocompatible with your own teeth structure. For anxious patients, this new technology means less time in the dental chair.

Drill-less Dentistry with Air Abrasion

For many patients, the sound of a drill is enough to send them running in the other direction. Fortunately, new air abrasion is eliminating the need for intimidating dental drills and anesthetic injections. This conservative, less traumatic alternative to drilling uses powerful particles of aluminum oxide to selectively remove decay. This greatly reduces heat and vibration, two leading sources of pain and discomfort traditionally associated with dental drilling.

While air abrasion can only be used for a limited number of procedures, including treating small cavities, removing surface stains and preparing teeth for composite fillings or bonding, it is a highly effective treatment for patients that are fearful of needles and noisy drills.

Laser Dentistry for Precise Dental Care

Gentle and precise lasers are transforming the way dentists can perform a variety of dental procedures, ultimately allowing dentists to treat diseased oral tissue without damaging surrounding, healthy tissue.

Using a precise, specialized beam of light that targets and destroys decay, laser dentistry reduces bleeding, swelling and discomfort, while requiring little or no anesthetic. From treating gum disease and lengthening crowns to treating cold sores and controlling orthodontic tissue, many dentists are using lasers as an alternative to traditional drills.

Your Pasadena dentist offers laser treatment for both hard and soft tissue. Laser MD for hard tissue reduces heat and vibration typical of drills by using a less invasive form of treatment that conserves the healthy tooth structure. For soft tissue treatment, Diode lasers can be used to non-surgically treat gum disease and remove plaque, selectively removing the infected tissues and promoting healing.

Receiving quality dental care and restoring your smile doesn’t have to be agonizing. In fact, new and innovative advancements in dental technology have made many dental procedures more precise, more convenient and more comfortable than ever. If you suffer from dental anxiety, express your concerns to your Pasadena dentist. He can help you determine the best, pain free technique for repairing and restoring all of your dental needs.
