From ancient times, humans have developed distinct methods for alleviating the pain produced by diseases. The prescription of medications has come together fundamentally in the clinical and odontological practice from past times. Medicines play an important role in the general status of the patient after performing an adequate diagnosis and complete evaluation in which the signs and symptoms of the disease are analyzed, in order to establish the pharmacological and non- pharmacological measures for each patient and for disease type. The medical prescription is considered a scientific, ethical, and legal act of great importance on the part of the Dentist . Information on the pediatric use of drugs in some cases is incomplete. Studies on the utilization of medications in children are scarce; thus, it is important to be able to assess how medications are used, concretely analyzing their use in each situation, knowing the reactions that they can present, and the adherence that each patient presents to the treatment. Treatment adherence on the part of the patient is basic, as well as the indications of the patient’s parents in terms of the patient’s adequate taking of the medications and the pharmacological reactions, whether analgesic, antibiotic-therapeutic, or others  .
The most frequent pathologies in the oral cavity are of diverse origin and can give rise to lesions of the following types: infectious; traumatic; deficiency, or tumoral. Among infectious-type lesions, we find that these are produced in their majority by bacteria, viruses, or fungi caused by gingivitis, stomatitis, alveolitis, pulpitis, periodontitis, dentoalveolarabscesses, and ulcerations of diverse kinds. These produce pain and, in the greater part of cases, this is associated with inflammatory processes   .
However, dental pain has as its main cause the presence of dental cavities due to harmful stimuli in the dentino-pulpar complex . It affects children’s quality of life and is an important indicator of the need for odontological care . The use of analgesics, of non-opioid anti-inflammatory drugs that inhibit the biosynthesis of prostaglandins, and the use of antimicrobials comprises the treatment utilized under these conditions   . Lesions of the traumatic sort are accidental type, such as mechanical traumas or those that are the consequence of invasive-type odontological interventions such as exodontic procedures or diverse odonotological surgeries . Another of the less frequent, but highly important, reasons present in pediatric patients are autoimmune lesions generally compromising the entire body, but sometimes these have repercussions in specific zones of the oral cavity, for example, scleroderma, which gives rise to gingival retractions that can cause retractile cheilitis, or subgingival lesions, and another situation such as avitaminosis (principally due to a deficit of vitamin E and B-complex), which predispose in their majority to inflammatory lesions and infections .
Pain is a common problem in Odontopediatrics; it is considered a symptom and obligates the search for its origin in order to correct it. The patients can experience pain caused by an abscess, a periodontal lesion, orthodontic apparatuses, or other diseases of the soft and hard oral tissues . The management of pain should be individualized; according to the cause, severity, and chronicity, as well as in that the emotional state of the patient can, in some cases, give rise to disability according to the characteristics that it presents .
The analgesic action of NonSteroidal Anti-Inflammatory Drugs (NSAID) in Odontopediatrics is based fundamentally on inhibition of the enzyme CycloOXygenase1 and 2 (COX1 and COX2) directly on the membrane of the inflammatory tissue with effects at the central and peripheral level, with the consequent reduction of the synthesis of thromboxanes and prostaglandins . All NSAID are non-selective inhibitors of the enzyme cyclooxygenase, with the exception of acetylsalicylic acid .
According to the administration of antimicrobials to odontopediatric patients, 10% of the antibiotics that are prescribed are employed to treat oral-cavity infections, and with the therapeutic purpose (to eliminate the infection, diminish its severity, shorten its evolution, avoid general complications), in addition to their preventive purpose in patients with preexisting diseases (cardiological, non-trans- mittable chronic diseases, and immunocompromised patients) . In Odontopediatrics, first-choice antibiotics are penicillins; among these, Amoxicillin, which presents bactericidal action and good absorption by oral route (75% - 90%), can be administered with the ingestion of food. Its half-life is greater than the remainder of the penicillins; its mechanism of action is through inhibition of the action of the peptidases and carboxypeptidases, impeding the synthesis of the bacterial cell wall . Amoxicillin is associated with irreversible betalactamase inhibitors, such as clavulanic acid or the sulbactam pivoxyl; it permit the treatment of infections due to betalactamase-producing bacteria and is the drug-of- choice for patients who have been treated systemically, but who have not received adequate local treatment (chamber opening, drainage), with the persistence of the infectious symptoms . The extensive dissemination of resistance of antibiotics in pediatric patients obliges us to effect very much more prudent changes in their prescription, such as their use solely when they are useful for the patient, bearing in mind the possible bacterial pathogens implicated and the levels of resistance of each level, with the minimal impact possible on the respiratory and intestinal flora and adequate drug doses and duration to ensure efficacy, tolerance, and adherence to the treatment. One of the most important adverse effects of the penicillins is hypersensitivity, which can induce effects ranging from the most simple skin eruption to anaphylactic shock. Allergic reactions to Penicillin are described in 0.7% - 10% of exposed individuals, and anaphylactic reactions in fewer than 0.004% - 0.2%. Therefore, it is contraindicated in individuals with antecedents of anaphylaxis, urticaria, or eruptions immediately after the administration of Penicillin . Pharmaoresistance to antimicrobials is a worldwide, ever increasing problem generated by the indiscriminate and abusive use of penicillins . Thus, educative measures on the rational use of antimicrobials are necessary, in addition to the requirement for measures directed by medical health personnel to the parents of the children involved  . The most utilized antimicrobials in Odontopediatrics are presented in Table 1.
NonSteroidal Anti-Inflammatory Drugs (NSAID), as the pharmacological treat- ment-of-choice in Odontopediatrics in dental pain , is indicated because of their analgesic action; their mechanism of action comprises the inhibition of the cyclooxygenase enzyme at the central and peripheral level, after the reduction of prostaglandin and thromboxane synthesis . The most utilized analgesics are depicted in Table 2. At present, there are no fixed rules for the calculation of the optimal dose of a drug, in that these dates are mainly based on the calculation associated with the Body Weight (BW) and not with other variables  . The multiple approximations that have been described reveal the true complexity of this problem. Utilization of the age of the child as reference for the adjustment of the dose can cause serious errors on not taking into consideration the wide variations in weight of children within the same age group  .
Medication reconciliation is the process of creating the most precise list possible of all the drugs that a patient takes. The substantial amount of drugs that are currently available and the variety of indications for their use can render the process very difficult to prescribe or administer any drug necessary for dental treatment   . A precise history of medications allows the oral caregiver to evaluate the general health and disease status of a patient, the effect that medications exert on the dental treatment, and the possible contradictions and synergic or antagonist effects among the medications . There are two important tasks in order to obtain successful results in medication reconciliation to determine the medication that the patient is taking at present, and to ask whether the patient has some allergy to drugs, foods, or other substances  . If the purpose of the drug is not included on the label of the container, the patients
Table 1. Pediatric NSAID doses and the antimicrobials most utilized by oral route in Odontopediatrics .
Table 2. Pediatric doses of NSAID most utilized via oral route .
should be asked why they are taking the drug. Many drugs that have been on the market for a long time are utilized to treat diseases for which they were not originally prescribed  . The objective of medication reconciliation is to diminish possible errors in medication (Table 3), and possible medication interactions, in addition to detecting risks to the patient’s health  . This is conducted without judging the medical practice or questioning individual clinical decisions, but instead to detect and correct possible Errors of Prescription (EP) that could go undetected during the clinical practice    .
The objective of this work was the pharmacotherapeutic follow-up associated and supported by current clinical guidelines for the management of pediatric patients presenting at the UAO/UAZ Odontopediatric Clinic, In addition, the aim was the registration of each patient individually to describe schemas and protocols in relation to the rational use of antimicrobial and NonSteroidal Anti-Inflammatory Drugs (NSAID) in pediatric patients.

2. Material and Methods
An observational, exploratory, transversal-type study was developed. The study population was recruited in Integral Clinic of the Odontopediatric Specialty (CLIO) of the Academic Unit of Odontology (UAO) of the Autonomous University of Zacatecas (UAZ), from August 2019 to August 2020. In the selection criteria included: patients between two and twelve years, presence with or without pain, require pharmacological treatment (antibiotic and analgesic) and accept to participate in the study. For the exclusion criteria: patients who do not accept to participate in the study. Patients lose the evaluation instrument, patients do not return for an appointment and uncooperative patient. Twenty- three patients came to clinical care were included in the study population. The follow-up time was per 15 days in each patient. In the other hand a retrospective review of the clinical files of 35 CLIJANI patients, for whom authorization was requested to consult with and determine whether the variables and the criteria studied in our work are considered in the practice.
3.1. Study Population by Gender and Age of the Patients
There were 23 children who attended the Care Clinic for diverse reasons in the Odontopediatrics Speciality Program, among whom 30.4% were feminine gender and 69.6%, masculine gender. With regard to the patient’s age, we are able to observe that the most frequent mean age for the study group was 7.56 years, the most frequent age group was 9 years with five patients, and six patients were between the ages of 3 and 5 years. One of the main reasons for consultation with the Odontopediatrician is the presence of cavities and, in many cases, pain; only 34.7% of the study group referred pain, while the remaining 65.3% manifested the absence of this.
3.2. Pharmacological Interview
On carrying out the interview on pharmacotherapy with the parents or guardians who accompany the patient, 91.3% of the pediatric patients were not administered pharmacological treatment. The latter was administered only to 8.7%, which corresponds to two patients. These patients referred the administration of some medication related to oro-dental problems prior to knowing the patient’s diagnosis.
3.3. Dental Diagnosis of the Patients
With regard to distribution in absolute values according to the dental diagnosis referred by the Medical Residents in the Odontopediatrics Specialty of the Autonomous University of Zacatecas, it is reported that 47.08% of the patients presented pulp necrosis, 26.09% presented irreversible pulpitis, and the remaining 26.09% presented dental diagnoses such as acute periapical periodontal abscess, cellulitis, apical perforation, the persistence of teeth temporary and dental avulsion (Table 4).
3.4. Post-Odontological Pharmacological Treatment
The pharmacological treatment-of-choice prescribed by the Medical Residents of the Ondotology Specialty was antibiotic therapy in 91.30% of cases, while in 8.70%, the administration of an analgesic was indicated. Among the antimicrobials prescribed, in 34.72% of patients an Amoxicillin suspension of 250 mg/ml was indicated, while 26.04% of patients were prescribed a suspension of Amoxicillin with clavulanic acid 250 mg/62.5mg/5ml. On the other hand, it was observed that 8.68%, equivalent to two patients, were prescribed an analgesic, indicating to us that the majority of patients who enter the Odontopediatric Specialty Clinic for a diagnosis present dental infections (Table 5).
3.5. Pharmaco Therapeutic Follow-Up (PTF)
One important aspect for the success of any treatment is following the instructions precisely and, needless to say, the adequate administration of the medications. In order to know the degree to which the patients follow the indications for the pharmacological treatment, the parents or guardians were provided with a registration sheet on which the time and the number of days that they followed the indications were noted. According to the latter, of the 21 patients who were

Table 5. Distribution of patients according to the post-Dx pharmacological treatment.
indicated an antibiotic, 78.26% of these complied with the indications for a 7-day time period; in addition, 4.34% corresponds to one patient for 5 days, one patient for 3 days, and one patient was administered a unique dose. In the case of analgesics, the two patients who were indicated the latter complied with the prescribed treatment for 3 days or with its suspension on disappearance of the pain.
3.6. Dental Pharmacology in Patients with Pathologies
With respect to Pathology (Table 6), three of the patients presented interventricular communication; one had idiopathic pulmonary hypertension, and one, cardiac murmur. The systemic afflictions of the five patients, as well as the data provided by their clinical history, in addition to the indications in relation to the oro-dental diagnosis for each of the patients, were taken into account. Only one of these five patients was found under treatment; therefore, in coordination with the Pediatric Cardiologist, prophylaxis was established with antibiotics. These patients were referred to the Pediatric Cardiologist for their assessment, prior to treatment and to the administration of the medications, in order to establish a coordinated treatment.

3.7. Pharmacotherapeutic Follow-Up in CLIJANI/UAO-UAZ Clinics
With the purpose of identifying whether there are some pharmacological-follow- up protocols at the UAO/UAZ Kindergarten Clinics, a review was conducted of the clinical histories of 35 children in attendance during the August 2019-July 2020 academic school-year cycle, taking into consideration the same variables of the UAO/UAZ Odontopediatric Specialty Clinic, that is, children aged between 4 and 5 years (77.1%) and a small proportion of care for three children aged 2 years and one aged 7 years, with an average age of 4.68 years and a Standard Deviation (SD) of ±0.9. It was reported that 71.42% of patients presented grades 1 and 2 caries, 8.57% had pulp necrosis, and the remaining 20.01% presented dental diagnoses such as irreversible pulpitis, localized gingivitis, fluorosis, malocclusion, and persistence of the temporary dental organ.
According to the reason for the consultation and the presence of pain, only 6% of the children seen referred pain, while the remaining 94% did not cite the latter. According to the clinical histories, highlighting medication reconciliation, none of the patients received pharmacological treatment or were at this timeunder some medicinal therapy, and none had some disease of systemic origin, where it was observed that the patients were under pharmacotherapeutic follow-up.
Pediatric patients are distinct from adult patients in their metabolic behavior and in their response to a certain medication. This makes it necessary to determine the exact dose of the drug, the administration route, the duration, and interactions with concomitant therapy and, of course, the registration of any adverse reaction presenting during the administration of the treatment.
In the work carried out, it was observed that there is no adequate adherence to the pharmacological treatment in pediatric patients who presented at the CLIO of the UAO/UAZ, in that among 100% of the medicated patients; only 2% complied with their pharmacological treatment. That is to say, 2% followed the schedule and the frequency indicated in their pharmacological treatment, indicating to us that the mothers and guardians responsible for the patients did not have a control of the schedule and frequency at the time of complying with the taking of each medication indicated. These findings are in agreement with what has been reported; there is a disconnection from the indications of the pharmacological treatment, with medications being taken outside of the time indicated, or early suspension prior to the schedule for completing the schema, this generating microbial resistance, diminishing or modifying the response of the patient to the medication. It is of the utmost importance for the Odontopediatrician to perform medication reconciliation in each of the patients with or without medical treatment, as well as vigilance of the patients’ pharmacological treatment.
The Investigation Project was carried out thanks to the collaboration of the Odon- topediatric Specialty Clinics (CLIO) and of the Kindergarten (CLIJANI) of the Academic Unit of Odontology of the Autonomous University of Zacatecas, Zacatecas City, Mexico, which permitted the revision of patients and their pharmacological follow-up in Pharmacology (CLIO),as well as the retrospective review of the clinical files (CLIJANI).Our thanks go to Consejo Nacional de Ciencia y Tecnología (CONACyT) for the grant for postgraduate studies to Cristina Jareth Montañez-Sosa, postgraduate student of the UAO/UAZ Odontopediatric Specialty.
