Common Medications prescribed in pediatric dentistry. • Introduction; • Several categories of medications prescribed by dentist to manage a variety of diseases and conditions associated with oral cavity; i.e Bacterial , fungal ,Viral , pain and caries prevention. prof s.m.omar 1 INTRODUCTION • Body of the pediatric patient is not simply a miniaturized version of his adult counter part. child physiology and anatomy significantly differ from those of adults. • Pediatric dentist must consider this differences when making therapeutic choices about young patient. prof s.m.omar 2 CONTNU.. • In pediatric patient administration of drugs is complicated by the necessity to adjust the dose to accommodate their lower weight and body size. so the pediatric patient can not be given adult dose. Therefore adjustment of the dose in pediatric patient is necessary. prof s.m.omar 3 Cont.. • PEDIATRIC DRUG DOSAGE prof s.m.omar 4 Cont.. Drug (WHO definition) Any substance or product that is used or intended to be used to modify or explore physiological system or pathological states for the benefit of the recipient. prof s.m.omar 5 Cont… DRUG ; -- ANY SUBSTANCE USED TO DIAGNOSE TREAT, RELEIVE, CURE OR PREVENT DISEASE • --MAY ALSO BE USED TO ELIMINATE PAIN OR ALTER MOOD OR BEHAVIOUR • -- HAS THE POTENCY TO CHANGE ONE OR MORE BODILY FUNCTIONS • prof s.m.omar 6 DRUG DOSAGE DOSE ;.. IS THE AMOUNT OF DRUG THE PATIENT TAKES OVER A GIVEN PERIOD OF TIME. • FACTORS TO BE CONSIDERED WHEN DISPENSING A DRUG• AGE OF THE PATIENT, • WEIGHT OF THE PATIENT, GENDER, • TIME OF THE DAY THE DRUG IS TO BE TAKEN AND • THE DRUG FORM prof s.m.omar 7 Dosage forms: Solid dosage forms--Powders, granules, tablets, capsules etc. Liquid dosage forms Aqueous solution Syrup, liquids, injection etc. Aqueous Suspensions Mixtures, emulsions etc. Dosage forms for external use: Liniments, lotion, ointments, paste, gel aerosol, suppositories, transdermal adhesive patch etc. prof s.m.omar 8 Drug Dosage Dose is the appropriate amount of a drug needed to produce a certain degree of response in a patient. Therapeutic dose In clinical practice, the required amount of drug in wt, volume, moles/international units, that is necessary to provide a desired effect. prof s.m.omar 9 Drug Dosage Dose is the appropriate amount of a drug needed to produce a certain degree of response in a patient. Therapeutic dose In clinical practice, the required amount of drug in wt, volume, moles/international units, that is necessary to provide a desired effect. prof s.m.omar 10 Factors influencing drug dosage Dosage literally means the method of dosing and represents a decision about 4 variables: a. The dosage form and the amount of the drug to be administered at one time. b. The route of administration c. The interval between doses and d. The duration prof s.m.omar 11 Rules for drug dosage.. CALCULATION OF PEDIATRIC DOSE prof s.m.omar 12 Rules of drug dosage.. • No rules guarantee the efficacy and safety of the drugs in children. • Dosage requirements constantly changes as a function of the body organs and age. • Dosage based on body weight, age, is practical but not ideal concept prof s.m.omar 13 Rules of drug dosage… • Adjustment of dosage in pediatric patient • Several rules exist to compute the dose for drugs for child. • Clark rule , which based on the typical adult weight ( 70 KG, or 150 LB ) prof s.m.omar 14 Rules of drug dosage…. Child dose = child’s weight (kg) x adult dose ------------------------------------70kg( typical adult weight) prof s.m.omar 15 Rules of drug dosage.. • child’dose = child’s weight(lb) x adult dose ----------------------------------------150(lb).typical adult weight prof s.m.omar 16 Rules of drug dosage • Young’s rule This rule based on the age of the child regardless of the weight. It is to divide the age of the child by the age of the child +12 and the resulting fraction is multiplied by the adult dose. prof s.m.omar 17 Rules of drug dosage • Catzel’s rule It offers a safe guide based on the surface area and expressed as a percentage of adult dose for a patient. Age in years % of adult dose 1 25 3 35 7 50 12 75 prof s.m.omar 18 • Use of safe recommended dose. • Reco dose x child weight • ---------------------------------• No. of time intervale. • Rec safe dose,, from drug references • i.e Ampicillin 25-50mg/kg/body wt prof s.m.omar 19 Rules of drug dosage… • EXAMPLE.,, • Calculation dose of Ampicillin for a child weighing 38 lb. • The usual adult dose is 2000 mg in 4 divided dose • Clarks rule – weight of the child lb /150 x adult dose. • 38/150 x 2000= 500mg in 4 divided dose prof s.m.omar 20 Rules of drug dosage * Prescription writing for pediatric patients prof s.m.omar 21 PRESCRIOION WRITING • Prescription, • is an order from prescriber ,, doctors ,or legally licensed person,, to the pharmacist for particular medication for specific patient. prof s.m.omar 22 Components of written prescription All written prescription should contain • Prescribers full name and address, telephone number and register number. • Patients full name , address, age and sex. • Date of issuance .

Expressed numerically, a 1:1000 preparation of epinephrine would be 1 gram epi 1000 cc’s solution 1000 mg epi = 1000cc’s solution prof s.m.omar = 1 mg epi 1 cc 84 Local anesthetics - vasoconstrictors Therefore, a 1 : 200,000 solution of epinephrine would be 1000 mg epi 1 gram epi 200,000 cc’s solution = 200,000 cc’s solution or 1 mg epi 200 cc solution prof s.m.omar = 0.005mg/ ml 85 Local anesthetics - vasoconstrictors • Because of ;.. • • • • * high tissue perfusion * high BMR. *High cardiac output. which lead to rapid clearance of local anesthesia from the tissue into the circulation, therefore, the L.A used for children should contain V.C , to reduce the rapid clearance of L.A from the tissue, and increase the duration of L.A , and reduce the level of toxicity. prof s.m.omar 86 Local anesthetics - vasoconstrictors • Calculation of L.A for pediatric patients; .The recommended dose for pediatric patient is; 4.4mg/ kg| BW. ( maximum dose) prof s.m.omar 87 Local anesthetics - vasoconstrictors • Example:.. Pt weighing 20kg, the maximum dose is 20kg x4.4mg L.A = 88mg local anesthetic agent. prof s.m.omar 88 Local anesthetics - vasoconstrictors Amind group is the most commonly use L.A agent in dentistry, i e Lidocaine. because of * high potency at low concentration. * less allergic reaction. * long duration. NOTE, CAUTION WITH PATIENTS WITH LIVE FUNCTION IMPAIRMENT. ‘ END’ prof s.m.omar 89 Oral surgery –pediatric dentistry • Minor Oral Surgery in Pediatric Dentistry prof s.m.omar 90 Definitions • Minor oral surgery – Is the part of dentistry that deals with the diagnosis and surgical treatment of diseases, injuries and defects of the human teeth, jaws, oral cavity and associated structures which, under normal circumstances, can be performed under local anaesthesia in an outpatient setting in most healthy and normal patients. – that can be performed under local anaesthesia with or without sedation (normally inhalational) or day-stay general anaesthesia in healthy children. prof s.m.omar 91 Setting up practice Two important things Clinician must be adequately experienced in the field Equipped with various tools of the trade that are essential for the safe practice of the minor oral surgery Surgical equipments A. Non- disposable instruments B. Disposable surgical instruments prof s.m.omar 92 MOS – 3 sets of instruments 1. 2. 3. Instruments for access and clear surgical field Instruments for manipulation or removal of surgical specimen Instruments for wound toilet and repair prof s.m.omar 93 Differences between primary and permanent teeth 1. Size. - Primary teeth are smaller in every dimension compared with their permanent counterparts. 2. Shape. - The crowns of primary teeth are more bulbous than the crowns of permanent teeth. The roots of primary molars are more splayed than the roots of permanent molar teeth. 3. Physiology. - The roots of primary teeth resorb naturally, whereas in the permanent dentition resorption is normally a sign of pathology. 4. Support. - The bone of the alveolus is much more elastic in the younger patient. prof s.m.omar 94 Modifications To Extraction Techniques In Children • Forceps- The beaks and handles are smaller. • In addition, to accommodate the more bulbous crown, the beaks are more curved prof s.m.omar 95 Modifications To Extraction Techniques In Children • The wide splaying of primary molar roots means that more expansion of the socket is required • Due to the relatively cervical position of the bifurcation in primary molars it is injudicious to use forceps with deeply plunging beaks (such as the adult cowhorn design) as these could damage the underlying permanent successors. prof s.m.omar 96 Differences between primary and permanent teeth • As primary roots are resorbed it is often preferable to leave small fragments in situ if the root fractures. • When part of a fractured root is visible then it should be removed. Blind investigation of primary sockets should not be performed as there is a danger of damaging the underlying permanent successor. • Similarly, blind investigation of the distal root socket of first permanent molar teeth must not be carried out in children with unerupted second molars, as unintentional elevation of the second molar can occur. prof s.m.omar 97 Extraction techniques PATIENT POSITION • Dental chair reclined about 30° to the vertical for extractions under local anaesthesia. prof s.m.omar 98 Extraction techniques Operators position Site Upper teeth Operators position Front of the patient Lower left Front of the teeth patient Lower right Behind the patient Straight back and the patient's mouth at a level just below the operator's shoulder The patient's mouth is at a height just below the operator's elbow Chair as low as possible to allow good vision prof s.m.omar 99 prof s.m.omar 100 prof s.m.omar 101 The non-working hand The 'non-working' hand also has important roles to play 1. It retracts soft tissues to allow visibility and access. 2. It protects the tissues if the instrument slips. 3. It provides resistance to the extraction force on the mandible to prevent dislocation. 4. It provides 'feel' to the operator during the extraction and gives information about resistance to removal. prof s.m.omar 102 prof s.m.omar 103 prof s.m.omar 104 • UPPER PRIMARY AND PERMANENT ANTERIORS Normal position – Removed by applying the forceps beaks to the root and then using clockwise and anticlockwise rotations about the long axis – In older children some additional buccal expansion may be required for the removal of the permanent upper canine. prof s.m.omar 105 UPPER PRIMARY AND PERMANENT ANTERIORS • Malpositioned permanent upper anteriors – Labially placed upper lateral incisors and canines have very little buccal support and are easily removed, either by using straight forceps applied mesially and distally and using a slight rotatory movement – Palatally positioned lateral incisors and canines are usually not accessible with forceps and thus elevators are used prof s.m.omar 106 UPPER PRIMARY MOLARS • Considerable expansion of the socket is required. • The initial movement after application of the forceps is palatal, to expand the socket in this direction. The tooth is then subjected to a continuous bucally directed force, which results in delivery. • Occasionally, buccal movement is not adequately obtained due to gross caries on the palatal aspect causing slippage of the forceps beak on the palatal side during buccal expansion. • This may be overcome by completing the extraction by continued palatal expansion. prof s.m.omar 107 UPPER PREMOLARS • Removed by buccal expansion using upper premolar forceps. • The upper second premolar is often single rooted and, can also be subjected to a rotation about its long axis to effect delivery. • Palatally displaced upper premolars are difficult to remove with forceps. The use of elevators in a manner similar to that described for palatally placed canines is preferred. prof s.m.omar 108 UPPER PERMANENT MOLARS • These teeth are removed using left and right upper molar forceps. • Following application of the forceps to the roots of the tooth (the pointed beak being driven towards the buccal root bifurcation) the tooth is delivered by expanding the socket in a buccal direction. • The use of palatal expansion is not as successful in the removal of permanent molars prof s.m.omar 109 prof s.m.omar 110 LOWER PRIMARY ANTERIORS • These teeth are extracted in the same manner as their upper counterparts, in that, rotation about the long axis using lower primary anterior or root forceps is employed. prof s.m.omar 111 LOWER PERMANENT ANTERIORS Permanent lower incisors are not readily removed by rotation as their roots are thin mesiodistally and rotation is likely to cause root fracture. The most effective method of removal is to apply lower root forceps and expand the socket labially. Permanent lower canines may be delivered by a rotatory movement about the long axis or by buccal expansion. Labially displaced lower canines - Mesial and distal application of forceps or straight elevators are used. The position of lingually placed lower anteriors normally precludes the use of forceps and straight elevators applied mesially and distally should be employed. prof s.m.omar 112 prof s.m.omar 113 LOWER PRIMARY MOLARS These teeth are removed by buccolingual expansion of the socket. Lower primary molar forceps are similar in design to the permanent molar forceps. They have two pointed beaks which engage the bifurcation. Lower primary root forceps are used by applying the beaks to the mesial root of the primary molar. Lower first primary molars are usually more easily removed with lower primary root forceps. After application of the forceps a small lingual movement is followed by a continuous buccal force, which delivers the tooth. prof s.m.omar 114 prof s.m.omar 115 LOWER PREMOLARS When these teeth are fully erupted in the arch of the young patient y removed by a rotatory movement around the long axis of the root using lower premolar forceps. Malpositioned lower second premolars are normally lingually positioned When lingually placed, lower premolars may be extracted using straight elevators applied mesially, lingually, and distally. Alternatively, it is often possible to apply the beaks of upper fine root forceps mesially and distally to the crown of the lingually placed tooth when the forceps are directed from the opposite side of the jaw. Gentle rotation of the tooth with the forceps may then effect removal. prof s.m.omar 116 LOWER PERMANENT MOLARS • The lower molar forceps have two pointed beaks that are applied in the region of the bifurcation buccally and lingually. • Once applied the forceps are used to move the tooth in a buccal direction to expand the buccal cortical plate. • When buccal expansion is not sufficient to deliver the tooth then the forceps should be moved in a figure-of-eight fashion to expand the socket lingually as well as buccally, and this is generally successful. prof s.m.omar 117 Post-operative instructions-for the child 1. The child should not be dismissed until a blood clot is 2. 3. 4. 5. 6. 7. formed Blood soaked gauze when removed from mouth should be disposed out of sight of the child Gauze to be hold between the teeth for half an hour Child is instucted not to bite his lip Do not disturb the area where tooth was removed Do not rinse mouth vigourosly for 24 hours after extraction Do not take juices with a straw for that day prof s.m.omar 118 Post-operative instructions-for parent 1. Reinforce what has been told to the child regarding the home care 2. A light meal with no hard food should be recommended for that day 3. Analgesic is prescribed and antibiotic coverage is done if the area was infected 4. Blood can appear on the pillow the next day. This represents a slight oozing of blood from the healing socket that gets mixed with saliva 5. Call the dental office if undue symptoms develop prof s.m.omar 119 Thank you prof s.m.omar 120
