Introduction: Prescribing is the act of indicating one or more drugs to be administered to or taken by the patient, its dosage, and the duration of the treatment. It is a dynamic and individualized clinical process. Prescription has unique characteristics, but it may be inclined by cultural, social, economic and promotional factors. Aim: The aim was to evaluate the knowledge of drug prescription in 3 rd year and final year students at a private dental college. Methodology: A semi-structured questionnaire was used to 150 male and female, 3 rd year and 4 th year students of a private dental college from April 2014 to May 2014. The questionnaire consisted of 10 open-ended questions. Results: The main reason for prescribing medication was pain. The most commonly used nonsteroidal antiinflammatory drugs were diclofenac, followed by paracetamol and ketorolac. The most extensively prescribed antibiotics were amoxicillin. The main reasons for errors done by students were limited knowledge about correct posology of drugs. Students get their information for drug prescription mainly from professors, followed by classmates and pharmacology course. Most of the students were unaware about the Guide to Good Prescribing by World Health Organization. About 56.67% students had knowledge about dose of the drug prescribed. Conclusion: Pain was found to be the most significant reason for drug prescription. Amoxicillin was the most widely used antibiotic. Lack of knowledge about the posology of drug was the main reason for the error done by students.

| Introduction|| |
Prescribing is the chief involvement that the majority of doctors recommend to sway their patients' health - no matter what profession medical graduates settle on to pursue, most will have to remain "specialists" in drug prescribing.  Prescribing is for that reason an indispensable skill for doctors in nearly all medical specialties. A good number of graduates will need not only an information of today's drugs, but also a stiff foundation in the principles of therapeutics, underpinned by a scientific understanding of drug action, to inform their learning about future developments. 
Prescribing is the act of indicating one or more drugs to be administered to or taken by the patient, its dosage, and the duration of the treatment. It is a dynamic and individualized clinical process. Prescription has unique characteristics, but it may be inclined by cultural, social, economic and promotional factors. 
Prescribing correct doses of appropriate drugs is an important aspect by which a physician may influence their patient's health.  As drugs can cause significant morbidity and mortality, and hence there comes the risk of causing great harm. Though newly trained doctors are frequently secluded from the requirement to commence high-risk practical procedures but they are frequently anticipated to prescribe potent drugs from their 1 st day of clinical work. 
Interim treatment or treatment explicitly for surgical procedures is provided by dental prescriptions. However, awareness about drugs will be required by dentists, and they must pursue the international rules for prescribing. There is evidence that in countries like Mexico, dentists often do not have the appropriate pharmacological information, and thus, at times make prescription errors. ,,
In general practice, Drug therapy is the mainly used method of any disease treatment. Rational drug prescription is defined as using the least number of drugs to obtain the best possible effect in the shortest period and at a reasonable cost.  Precise diagnosis, appropriate prescription, accurate dispensing, apt packing and patient devotion are the five essential criteria to attain the balanced drug use. Inapt drug prescription is an occurrence around the world. Its penalty comprises exacerbation or persistence of illness, ineffective and unsafe treatment, anguish and damage to the patient, and elevated costs. ,,,
The current instructional method for teaching in various dental colleges, in India, is problem-based learning as it has been recognized worldwide. Prescription writing ability, a part of rational prescribing of medicine is being educated in zero unit (the education related to prescription writing starts at the same time when the student started doing clinical work). It is the just teaching program associated to the subject.
Thus, the aim of this study was to evaluate the prescribing skill of third and final year students of bachelor of dental surgery (BDS) as the students' starts their clinical work from 3 rd year onward.
| Methodology|| |
A survey on the knowledge related to drug prescription was approved by the Institutional Review Board of a private dental college. A semi-structured pretested questionnaire with 10 open-ended questions was used for the study. The study was conducted at a private dental college in Uttrakhand, India, during the period of 1-month from April 2014 to May 2014.
Development of the questionnaire
A pilot test was conducted on 30 students who were not incorporated in the main study to check the validity and reliability of the questionnaire. The testing and retesting of the questionnaire was done. A reliability coefficient (α) of 0.80 or more was considered acceptable. Further modifications were done in the questionnaire. The questions were rephrased, reframed, added, and removed from the questionnaire.
Then the questionnaire was distributed among 150 3 rd year and 4 th -year students. Students with age 21-25 years equal number of girls and boys were included in the study. Informed consent was obtained from the participants before administration of the questionnaire.
Contents of the questionnaire
The questionnaire consisted of 10 open-ended questions:
- What is the most common health conditions treated in dental practice?
- Which is the most common nonsteroidal antiinflammatory drugs (NSAID) you prescribe?
- Which antibiotics are most commonly prescribed?
- What are the most common errors occur during prescription of drugs?
- What are your sources for prescription information?
- Do you use World Health Organization (WHO) Guide to Good Prescribing for drug prescription?
- Do you have appropriate knowledge about dose of Drug to be Prescribe?
- Do you know about the frequency of Drug to be prescribe?
- Do you know for how long the drug has to be given?
- Did you know the correct route of drug delivery?
Data analysis was performed using SPSS version 17(Softonic, Barcelona, Spain) and data were presented in tabular and graphic form. Test of significance was done using Chi-square statistics with P < 0.05 considered as significant.
| Results|| |
A total of 150 third year and final year students, both girls and boys participated in the study. P =0.004 was found while co-relating knowledge about drug prescription between 3 rd year and final year students. Hence, the difference was statistically significant among the knowledge among final year students and 3 rd year dental students.
Most common health conditions treated in dental practice: To this question majority of respondents answered pain (50%) as the main reason for prescribing medication [Figure 1].
Most common nonsteroidal antiinflammatory drugs prescribed: The most common NSAID prescribed was diclofenac (34.67%) [Figure 2]. Most common antibiotics prescribed: Maximum number of students (46%) prescribed amoxicillin for majority of infections [Figure 3]. Most common error during prescription: 50% of students did error during prescription due to wrong posology [Figure 4].
Sources of prescription information: 34.67% students sought information for prescription from professor [Figure 5]. WHO Guide to Good Prescribing used: 55.33% answered that they don't know about this book [Figure 6].
Knowledge about dose of the drug prescribed: 56.67% of the students answered that they know about the dose to be given to the patient. Frequency of drug to be prescribed: 60% of students answered that they know how many times the drug had to be prescribed. Knowledge of duration for which drug has to be prescribed: 61.33% of the students knows for how long the drug had to be given. Knowledge about route of drug delivery: 67.33% of the students know about the route of drug administration [Figure 7], [Figure 8], [Figure 9], [Figure 10].
| Discussion|| |
In India (according to Dental Council of India), students take a pharmacology course in their 2 nd year BDS that covers prescribing and knowledge regarding pharmacology and pharmacokinetics. It is the liability of the institution and the faculty to create awareness  and educate students to become highly skilled in their professional practice. Students are not entirely responsible for prescribing as they prescribe under the guidance of seniors. 
The most common health conditions treated in dental practice in the present study is pain, which is in disagreement with the study conducted by Guzmán-Álvarez et al. wherein the most frequent reason for prescription is infection. Infection leads to pain so it should always be treated. Appropriate diagnostic procedure should be used to know the type and the origin of the pain are very essential so that suitable treatment can be implemented. ,
To be acquainted with the pharmacokinetics and pharmacodynamics of all NSAIDs is an essential aspect of their suitable use as well as the general properties that they share and the small differences between drugs.  Majority of students have the habit of prescribing diclofenac and paracetamol (34.67% and 30% respectively), which is in contradiction with previous studies in which maximum students prescribed ibuprofen.  Paracetamol can be prescribed alone, but it has less antiinflammatory properties. However, it is the lone NSAID that possibly will be prescribed in amalgamation with other NSAIDs. , About 15.33% of the students mentioned ketorolac as their first preference; ketorolac is an exceptional analgesic, but it is not as efficient as an antiinflammatory, it is potentially nephrotoxic as well as it is enormously irritating to the stomach. Thus, it should be administered for not >5 days, and the patient be required to drink abundance of water to guard the kidneys. About 10% and 8% of students prescribe Naproxen and aspirin, which is in contradiction with previous studies. ,
Amoxicillin outweigh the result with 46%. This is prescribed by maximum number of students (69), which is appropriate because it is the first choice in dentistry. , According to the American Heart Association,  antibiotic combinations can be prescribed for patients with systemic diseases mainly heart disease, recommends high doses of different antibiotics 30-60 min prior to commencement of the dental procedure, but it was not so any of the present case.
Wrong drug posology (50%) was the most common prescription error done by students which is in total agreement with the previous study.  This is a serious issue, in view of the fact that it affects patient health and safety. Not asking about patient's allergies, wrong duration of administration will undeniably lead to therapeutic failure, and this could worsen the patient's condition and may result in toxicity.  Not knowing what to prescribe, Improperly filled out prescriptions is a frequent problem and compromises patient safety. To avoid the problem of not knowing brand names, the WHO Guide to Good Prescribing recommends making a customized list including the essential drugs for each health care professional who prescribes drugs at the clinic. ,,,,,,,,,,
Most of the students (34.67%) gather their information for prescribing from their professors, which is in agreement with previous study,  to get information from professors is good as this is stage of the student's development, but approximately 20.67% students still rely on their classmates for advice which is a lot more than previous studies.
About 55.33% of students were not aware of WHO guidelines for prescribing which is tremendously more than previous studies while 10% follow the indications while prescribing which again lesser than previous studies.
The main limitations of this study were that only 10 open-ended questions were used to conduct the survey, and a small sample size was considered.
Future studies should evaluate prescription practices among teachers and general practitioners. Further studies in this field should be done to know the overall prescription writing skills of the students.
| Conclusions|| |
Pain was found to be the most significant reason for drug prescription. Amoxicillin was the most widely used antibiotic. Lack of knowledge about the posology of drug was the main reason for the error done by students. Professors were the main source of knowledge about the prescription of drugs. There was a lack of knowledge related to WHO guide to good prescribing.
The knowledge of prescribing drugs is of utmost need for good dental practice and hence, it is essential to expand the knowledge related to pharmacological therapy and to know about the proper therapeutic guidelines.
