To Find Out the Causes of Extraction of Teeth in the Patients Coming to the Department of Oral and Maxillofacial Surgery at Kantipur Dental College Teaching Hospital and Research Center from January 2014 to December 2018

Objective: The main objective of this study is to find out the reasons for the extraction of the teeth on patients visiting to the Department of oral and maxillofacial surgery at Kantipur Dental College Teaching Hospital and Research Centre from 2014 January 1st to 2018 December 31st. Materials and methods: The patients came to the department of oral and maxillofacial surgery department during the year 2014 January to 2018 December for the extractions were retrospectively analysed for age, sex and the reasons for the extractions were found out. Results: 18720 extractions were performed in 18720 patients. Here we selected the patients who went only single tooth extraction, so the extraction number of tooth and patient number are same. An age range of 10 to 110 years of patients were included. In patients. Dental caries (20%) seem to be the most common cause in case of males and wisdom tooth (19%) is the most commonly extracted tooth in case of females seen in our study. RCT failure (0.76%) is the least common cause for extraction in case of males and cystic lesion (0.84%) is the least common cause for extraction in case of females.

Clin Oral Sci Dent, an open acess journal Volume1 • Issue1 • 2019 Range of 18-110 years with a mean (± standard deviation) of 34.8 (13.3) was observed. Most of the patients were in the 21-30 years age group accounting for 35.7% of cases. The difference in proportions of reasons for tooth extraction between the gender was statistically significant (P=0.02; df=24). The difference in the reasons for extraction among the age groups was statistically significant (P<0.001; df=132). Conclusion: Dental caries and wisdom teeth extraction is the most common cause for the extraction of teeth in the patients coming at the department of oral and maxillofacial surgery in Kantupur dental college teaching hospital and research center. Dental caries is the preventable disease, hence there is need of more awareness programmes for preventing the disease and even simple fillings only can save the teeth in large scale. Periodontal diseases also can be prevented or cured so that we can save the teeth of the patients. Most of the people have low income, so they want to go for extraction instead of saving them. Introduction Nepal being the developing country, we find most of the people going dental extraction even the teeth can be saved. Tooth extraction is the most common surgical procedure performed in the oral and maxillofacial surgery department. Extraction seems to be simple procedure but it has significant impact in quality of life in individual’s life. Quality of general health and psychological consequences is totally hampered after extraction of tooth [1]. Globally, tooth loss has become a global public health concern [2,3]. Inspite of being preventable, dental caries has become the most common cause for extractions of teeth [4,5]. Similarly in our study too dental caries is the common cause for extraction of teeth and wisdom teeth being the second cause where as in other studies periodontal cause being the second cause for the extraction of tooth. Oral hygiene status of the patients, education level, socioeconomic status and individual quality of life always determines the extraction of tooth [3,4,6]. Not only has this, in today’s world eating patter of population had much bad impact in oral hygiene which also have great role in extractions [7,8]. Different kinds of oral diseases and etiological factors exhibit interand intra-regional variations [9]. Very few studies are found about extraction in our country and this seems to be the first entity to the best of our knowledge (Table 1). Age groups (Years) Gender Total
