Abstract Among pharmaceuticals used in the Czech Republic, in which the effects on orthodontic treatment have been proven or which show impact on other factors (e.g. salivation or gingival hyperplasia) belong antibiotics, inhibitors of prostaglandines synthesis, regulators of blood calcium levels, antiepileptic drugs, immunosuppressives, application of growth hormone and parasympatholytics. Other prescription drugs may have side effects manifesting in oral cavity. However, the influence on orthodontic treatment has not been proved yet. The coordination between pharmacotherapy, health state of a patient, and conditions for orthodontic treatment should be taken into account when planning orthodontic treatment (Ortodoncie 2013, 22, No. 3, p ).

It is, therefore, necessary to consider the fact that effects of individual drugs manifest not only in a human body (and may complement one another) but may - to some extent - influence the outcomes of orthodontic treatment. Drugs are used in many branches of medicine for their desirable effects, however, in orthodontics those who are not informed may be taken by surprise with their undesirable impact. Therefore we should be aware of the following important information. redakce@orthodont-cz.cz 179

Jako doporucï enõâ se uvaâ dõâ co nejvõâce zkraâ tit terapii touto skupinou leâ kuê prïiortodontickeâ leâcïbeï [7]. ± COX neselektivnõâ: Jejich zaâ stupcem je ibuprofen. Inhibuje cyklooxygenaâ zu 1 i2 a tõâm snizï uje pocï et Amongst the drugs which may affect orthodontic treatment we find antibiotics, prostaglandines synthesis inhibitors, blood calcium level regulators, antiepileptic drugs, immunosuppressives, recombinant growth hormone and parasympatholytics. The aim of our report is to comment on potential impact of the drugs mentioned on orthodontic treatment. Antibiotics Antibiotics are either product of microorganisms' metabolism or are produced synthetically. Their purpose is to eliminate originator of a disease or inhibit its growth. They are indicated whenever the balance between microorganism and macroorganism is challenged. Doxycycline, belonging to tetracycline-type antibiotics, is the only medication which is related to orthodontic movement. The side mechanism of its effect inhibits activities of metalloproteinases (collagenase and gelatinase) and impedes collagenolysis. Thus the number of osteoclasts is reduced, root and alveolar bone resorption is slowed down, and orthodontic tooth movement is slower [1, 2, 3]. Prostaglandines synthesis inhibitors This group of pharmaceuticals includes non-steroid antiphlogistics and analgesics-antipyretics. Their purpose is to inhibit creation of prostanoids (prostaglandines, prostacyclines, and thromboxanes) which serve in a human body as mediators of inflammation. Prostaglandines originate with the help of cyclooxygenase (COX) 1 or 2, or from arachidonic acid, and they affect e.g. blood pressure, platelet aggregation, blood vessel tonus, urinary bladder tonus, and bone resorption. Prostaglandines synthesis inhibitors are subclassified into: ANALGESICS-ANTIPYRETICS An example is paracetamol. Paracetamol has virtually no anti-inflammatory effects, and it accelerates transformation of prostaglandines into less effective forms [4]. It has no impact on orthodontic tooth movement [5]. Therefore, paracetamol may become the drug of choice in case of painful orthodontic treatment [5,6]. NON-STEROID ANTIPHLOGISTICS ± COX 1 preferential: The most frequently used is acetylsalicylic acid. Apart from inhibition of thrombocytes aggregation it reduces the number of osteoclasts and slowes down bone resorption. Thus orthodontic tooth movement is slower. The effects were proved in the study with guinea pigs - dose of 100mh/kg 2x daily [5]. However, it is recommended to reduce the therapy with these pharmaceuticals during orthodontic treatment [7]. ± COX non-selective: An example is ibuprofen. Ibuprofen inhibits cyclooxygenase 1 and 2, and thus redu redakce@orthodont-cz.cz

Jeho tvorbu stimuluje parathormon. Bylo prokaâ zaâ no, zï e u krys prïilokaâ lnõâm ces the number of osteoclasts as well as bone resorption. Therefore, it results in slower orthodontic tooth movement [5,8]. ± COX 2preferential: An example is meloxicam. No impact on the number of osteoclasts or orthodontic movement has been proved [9]. ± COX 2selective: The group is represented by the so called coxibs. They have a highly selective effect only on cyclooxygenase 2, and side effects (especially on the gastrointestinal system) are negligible. However, their use leads to slower orthodontic tooth movement [10]. Ca regulators Calcium is an essential component in many physiological processes of homeostasis in a human body. Its regulators include some hormones, vitamins, and synthetic pharmaceuticals known as bisphosphonates. ± parathormone: made by parathyroid glands, the secretion is stimulated by the receptor that reacts to decreased calcium concentration in blood. It leads to the increase of calcium ionts concentration and to the decrease of phosphate ionts concentration in blood. Chronic continuous administration of parathormone results in bone resorption due to differentiation and activation of osteoclasts, and thus in increased orthodontic tooth movement. Chronic intermittent administration stimulates osteoblasts, and thus results in increased bone mass. However, it doesn't seem to affect orthodontic tooth movement. The method of application and dosage are important [11, 12]. ± thyroid hormones: thyroxine and its active form triiodothyronine play an important role in psychological and physiological development of a human. They affect cellular metabolism and activity, aid in calcium absorption in small intestine, and thus take part in bone remodelling. They also support production of interleukins that stimulate differentiation of osteoclasts. During the administration (trials with rats used the dose of 5, 10 and 20 mg/kg/a day) or in case of excessive production, orthodontic tooth movement accelerates related to the dose applied [13, 14]. ± calcitonine: produced by parafollicular cells of thyroid gland. It is secreted in case there is an increased level of calcium in blood. It inhibits osteoclasts activity and stimulates osteoblasts which results in slower orthodontic movement of teeth [15]. ± estrogenes: hormones influencing, apart from other things, bone metabolism in women. They decrease bone resorption by inhibiting production of cytokines that are important for differentiation of osteoclasts, and thus they slow down orthodontic movement of teeth [16]. ± vitamin D3: supports absorption of calcium from intestine and its accumulation in bones. Production of vitamin D3 is stimulated by parathormone. It was proved that redakce@orthodont-cz.cz 181

NavõÂc in rats, when administered topically, orthodontic tooth movement slows down depending on the dose [20, 21]. ± Ca as a nutritional supplement: recommended daily allowance in adults should be between 1000 and 1300 mg. Calcium in the form of nutritional supplement is recommended for women after menopause and for men over the age of 65 as osteoporosis prevention. Insufficient allowance of Ca was proved to result in accelerated orthodontic tooth movement [22]. ± bisphosphonates: the group of pharmaceuticals indicated in bone metabolism disorder and in excessive bone resorption. They are primarily found in bones with higher metabolic activity. They establish a very strong bond with calcium and hydroxyapatite, and they are phagocytized by osteoclasts, in which they later cause apoptosis. Therapy using bisphosphonates may be complicated by osteonecrosis of a jaw which is the result of disorder in vascularization of bone tissue. Bisphosphonates slow down teeth movement as well as root resorption [17, 18, 19]. Anti-epileptic drugs Epilepsy seizure is a strong synchronous activity of a particular group of neurons. Medication aims to increase seizure threshold. The most frequent side effects in dental medicine include excessive hyperplasia of gingiva related to plaque due to administration of phenytonine, rarely also of phenobarbital. ( Note: Hyperplasia of gingiva is also connected to cyclosporine (see below) and inhibitor of Ca channel [23]). An orthodontist should help patients to facilitate oral hygiene; the recommendations include: non-extraction therapy, use of orthodontic brackets with a low profile, use of tubes instead of bands, finishing of Essix splints above the level of gingiva, no use of fixed retainers [24, 25]. Immunosuppressives Specific immuno-protection is related to lymphocytes proliferation. To suppress the proliferation, inhibitors with different selectivity are used. ± Antagonists of interleukin 1 and 6 and tumor necrosis factor (TNF): they suppress inflammatory reaction, and thus they also slow down movement of teeth and bone remodeling [26]. ± Cyclosporine A: suppresses transfer of signals to lymphocytes, increases activity of osteoclasts, and causes local osteopenia of alveolar process. It also accelerates orthodontic movement of teeth. Gingival hyperplasia is amongst frequent side effects [27]. ± Corticosteroides: inhibit production of cytokines, prostaglandines and TNF. They also suppress inflammatory reaction [28]. However, they accelerate orthodontic movement of teeth and root resorption. Due redakce@orthodont-cz.cz

Growth hormone Secretion of growth hormone (somatotropine) from anterior pituitary gland is controlled by two hypothalamic hormones: somatostatine and somatoliberine. Growth hormone stimulates proteosynthesis and cell differentiation. Secretion disorder may have a variety of causes. The lack of growth hormone results in growth disorders. To treat the deficit, recombinant growth hormone is administered, and the therapy lasts until the adult height is achieved. The therapy impacts facial skeleton development resulting in lower values of posterior facial height, bimaxillary retrognathia, greater gonion angle, and higher lower facial third, in spite of the fact that the hormone primarily influences chondrocytes in epiphysal cartilages, so that the expected facial growth should follow anteriorotation [31, 32]. Therefore, it is not possible to predict growth during the therapy, and orthodontic treatment should begin only after the medication is finished [33]. Parasympatholytics Parasympatholytics are specific antagonists found in cholinergic receptor of a muscarinic type. Atropine belongs to the group. Atropine inhibits the effects of acetylcholine which results in the falloff of salivary and sweat glands, lower secretion of mucus, lower tonus of smooth muscles, etc. Kuijpers et al (2010) focused on benefits of lower saliva secretion when adjusting fixed appliance [34].
