PHARMACOLOGY IN PEDIATRIC DENTISTS
PAIN AND ANXIETY
The vast majority of pediatric dental patients can receive their treatment in the conventional dental environment with appropriate techniques and pain behavior management.
In some cases the control of pain and anxiety needs to go beyond conventional techniques.
Drug therapy is indicated for children who can not be treated with traditional techniques of behavior management and local anesthesia.
Definition: Lower minimum level of consciousness that can independently maintain and further the permeability of the airway and respond appropriately to physical stimulation and verbal commands.
Conscious sedation levels:
- Light Sedation (oral)
- Sedation with nitrous oxide (inhaled)
** Deep sedation (rectal, nasal or IM)
MONITORING IN SC
- Pulse Oximeter
- Stethoscope Precordial
- Blood pressure cuff
The sedation technique that prevents the CETP. wake up easily and intentionally respond to verbal commands at all times, is by definition:
If conscious sedation techniques are applied properly and there is proper monitoring, patients present a cardiovascular and respiratory function properly.
When the patient suffers a partial or complete loss of protective reflexes and can not independently maintain airway apnea or hypoxemia may suffer, leading to danger.
Conscious Sedation Deep Sedation
OBJECTIVES OF THE CONSCIOUS SEDATION
-Reduce or eliminate the patient's anxiety and make you feel safe and comfortable so you can be a good dental treatment.
- Reduce the movements and reactions during treatment.
- Increase cooperation of the patient.
- Increase your tolerance for lengthy treatments.
- Assist in the treatment of compromised patients physically and psychically.
1 .- Pre-operative assessment of behavior.
2 .- Pre-operative assessment of oral health and general.
3 .- Collaboration, parental involvement and consent signed by them.
4 .- Economic considerations.
5 .- Treatment Alternatives.
6 .- Training and experience of staff and professional work.
CONSCIOUS SEDATION INDICATIONS
- Patients with pre-existing conditions:
* Patients with psychiatric disorders or mild mental
* Patients with moderate spastic muscle disorders or
- Patients with dental phobia (apprehensive adult), children are difficult to manage (not receptive)
- After surgery
- Patients ASA I and II
** Patients with intolerance to local anesthetics (anesthetic
** Patients with severe physical or mental disability (anesthesia
ASA CLASSIFICATION SYSTEM
Classification system used by the American Society of Anesthesiologists (ASA) to estimate the risk posed by anesthesia for the different states of the patient.
Class I non-healthy patients undergoing elective
Class II Patient with mild systemic disease, controlled and not disabling. May or may not relate to the cause of the intervention.
Class III Patient with severe systemic disease, but not disabling.
Class IV A patient with severe systemic disease and disabling disease, which is also a constant threat to life, and not always correctable by surgery.
Class V is the terminally ill or dying, whose life expectancy is not expected to exceed 24 hours, with or without surgical treatment.

INHALATION SEDATION: nitrous oxide
Gas inerteatóxico that produces sedation, relaxation and analgesia.
- Fast Blood levels (low solubility in plasma).
- When stopping his adm., Blood levels decline rapidly.
- Easy to control dose (not to exceed 50% in the pediatric patient).
- No serious side effects.
Children accept the use of mask (school age).
Children with anxiety and / or mild anxiety, but which cooperate with treatment.
- Children with serious behavior problems that do not cooperate
with the use of the mask.
- Children with nasal obstruction or respiratory problems.
- Agent weak.
- Lack of acceptance by the patient.
- Empowerment (combination with other sedatives).
- Adjustment step:
It starts with the maximum concentration of oxygen and nitrous oxide minimum and is getting adjusted according to the degree of sedation achieved (gradually increasing).
- Once achieved sedation to place the local anesthetic.
- After completion of the procedure should be given 100% oxygen for 5 min.
- Must maintain verbal contact with the child to promote relaxation and enhance cooperative behavior.
** You can make combination of midazolam sedation & nitrous oxide and hydroxyzine + nitrous oxide.
The pharmacological approach to control child behavior through conscious sedation is a very complex area and requires additional training and expertise.
The child with sedation failure may continue to be a control problem, while excessive sedation received you can quickly become a life-threatening emergency in the dental office.

Clavulanic acid is a beta-lactamase inhibitor, prevents bacteria from destroying amoxicillin.
It is indicated mainly in skin infections and soft tissue, including cellulitis and dental abscesses with cellulitis are often spread caused by Staphylococcus aureus, Streptococcus pyogenes, and Bacteroides spp. Some strains of these bacteria produce beta-lactamase, which makes it not susceptible to amoxicillin alone.

Infective endocarditis is an inflammation of the heart valves (endocardium).
Endocarditis is usually the result of bacteremia (bacteria in the blood), which is common during some dental procedures, among others.
Bacteria in the bloodstream can settle on damaged heart valves, and multiply to create a growth or mass of living bacteria. These masses can form clots that break off and travel to the brain, lungs, kidneys or spleen.
Most people who develop infectious endocarditis have underlying heart disease.
Streptococcus viridans, is responsible for nearly half of all bacterial endocarditis. Other common organisms are Staphylococcus aureus, S. epidermidis and E. faecalis.
Treatments that require prophylaxis:
All proce. dental manipulation involving tej. gingival or periapical region or perforation of oral mucosa
Dental procedures where prophylaxis is NOT recommended:
- Routine anesthetic injections in uninfected tissue.
- Taking Rx decay.
- Placement of prostheses or removable orthodontic appliances.
- Adjustment of orthodontic appliances.
- Placement of orthodontic Braquet.
- Loss of teeth.
- Bleeding from damage to the lips or oral mucosa.
- Patients with a history of EBSA.
- Congenital heart disease.
- Prosthetic heart valve.
- Recipients of heart transplants with patients. Heart
