Analysis Of 3667 Cases Of Permanent Teeth With Dental Pulp Disease

Objective: Because of the physiological structure characteristics of dental pulp tissue,pulp diseases can appear severe pain and hard to repair itself,have seriously affected the patients' quality of life.Dental pulp disease is a kind of common frequently-occurring disease in the crowd,and also is one of the highest of consultation rate in Chinese oral medicine diseases.In abroad,because of the popularization of oral health preventive knowledge,tooth diseases usually would not develop into the dental pulp disease before having treatment,and thus to the reports of the prevalence and the consultation rate of dental pulp disease are rare.Our country also has always been short of the epidemiological data of dental pulp disease.At present,during the reports about the study of dental pulp disease,there are a few scholars have investigated the prevalence of people in east area and middle area of China,or just some types is studied in cases of dental pulp disease characteristics,and lack of reports about analysis of all kinds of specific clinical characteristics such as gender,age,diagnosis,the tooth type and tooth position,therapeutic method of dental pulp diseases.The research through analysis of 3667 cases of permanent teeth with dental pulp diseases in our hospital,to study the clinical characteristics and influencing factors of general condition,diagnosis type,the tooth type and tooth position,geographical distribution characteristics and the therapy plan of the patients in southwest China.To provide some references for the prevention care and clinical diagnosis and treatment of dental pulp diseases.Methods: Permanent tooth which diagnosed as dental pulp disease were collected from January 2014 to August 2015 in oral medicine of southwest medical university affiliated stomatological hospital,and all the patients' related clinical data about age,gender,home address,clinical diagnosis,treatment and auxiliary examination results have been collected.All the original data has been inputted spreadsheet for data analysis,by using Excel,Graphpad prism6.0 statistical software.Results: 1.Totally of 3667 cases,whose age ranged from 7 to 93,1517 men(41.37%)and 2150 women(58.63%)contained,the male-female ratio was 1:1.42.2.The average age of sample population was(44.66±16.57).The male's average age was(45.33±16.72).The average age was(44.19±16.46)for female.The average age of patients with reversible pulpitis was(26.89±13.99).The average age of patients with acute pulpitis was(46.77±15.26).The average age of patients with chronic pulpitis was(43.98±16.94).The average age of patients with retrograde pulpitis was(55.41±11.48).The average age of patients with pulp necrosis was(45.82±16.84).The average age of patients with pulp calcification was(36.67±16.04).The average age of patients with internal resorption of tooth was(25.00±9.02).In contrast to the average age of sample population,different types of dental pulp disease have Statistically difference.3.There were 1185 cases of patients' age ranged from 45 to 59 in the overall sample,accounted for the largest proportion(32.32%)of the total sample.The constituent ratio of male and female's age interval have a remarkable difference(P =0.0027).The percentage of male cases within the range from 6 to 11 years of age(1.05%)was more than female(0.28%),and the percentage of male patients in 19 ~ 34 interval(20.63%)was less than women(25.07%),and the comparison of the two groups of data differences statistically significant(P =0.0017).4.The cases of chronic pulpitis had the highest proportion of the sample population(63.57%),and the cases of pulp calcification(0.65%)and internal resorption of tooth(0.19%)had the lowest proportion.In addition,to contrast the proportion of incidence of different diseases,the proportion of retrograde pulpitis of male's cases(6.00%)was higher than female's(2.23%)(P <0.0001),meanwhile,the proportion of chronic pulpitis of male's cases(61.50%)was lower than female's(65.02%)(P =0.0291).5.971 cases of involed tooth of overall sample were in the B zone,account for the largest proportion of 26.48% of the total sample.In addition,941 cases of involed tooth of overall sample were in the A zone,accounted for 25.66% of the total sample.847 cases of involed tooth of overall sample were in the C zone,accounted for 23.10% of the total sample.908 cases of involed tooth of overall sample were in the D zone,accounted for 24.76% of the total sample.The comparison of the four groups of data differences statistically significant(P =0.0064).6.370 cases of the left mandibular first molar count to the largest number of the overall sample,constituted 10.09% of total,and 5 cases of left mandibular lateral incisor count to the least number of the overall sample,constituted 0.14% of total.There were 1289 cases of the first molar in overall samples,which constituted the highest proportion of 35.15% of the total sample.There were 1110 cases of the second molar in overall samples,which constituted the second high proportion of 30.27% of the total sample.Meanwhile,there were 43 cases of canine teeth in overall samples,which constituted the lowest proportion of 1.17% of the total sample.And there were 48 cases of lateral incisors in overall samples,which constituted 1.31% of the total sample.Maxillary anterior tooth and maxillary premolars accounted for the proportion of overall samples with teeth(484 cases,13.20%)was significantly higher than mandibular anterior teeth and mandibular premolar area(281 cases,7.66%),and there is statistical difference between these two groups(P < 0.0001).7.There were 50 patients came from outside of Sichuan province(Guizhou,Yunnan,Chongqing,Heilongjiang,Xinjiang,Zhejiang,Gansu)and constituted 1.36% of the total sample.There were 123 patients came from Sichuan province except Luzhou(Chengdu,Mianyang,Nanchong,Yibin,Longchang,Neijiang,Meishan,Anyue,Zigong,Panzhihua,Aba),and constituted 3.35% of the total sample.There were 3138 patients came from the urban district of Luzhou(Jiangyang,Longmatan)and constituted 85.57% of the total sample.There were 356 patients came from outside the urban district of Luzhou(Naxi,Luxian,Hejiang,Gulin,Xuyong)and constituted 9.71% of the total sample.8.29 cases of calm treatment constituted 0.79% of the total sample,2970 cases of root canal treatment constituted 80.99% of the total sample,225 cases of mummification of pulp constituted 6.14% of the total sample and 443 cases of extraction of teeth constituted 12.08% of the total sample.Conclusion: Gender and age are influence factors to the prevalence rate and consultation rate of dental pulp disease in permanent teeth.The female's consultation rate is higher than male's of 3667 cases of dental pulp disease in permanent teeth.Various types of dental pulp disease has specific predilection age.Dental pulp disease in permanent teeth used to appear in middle-aged and elderly people.The consultation rate of young women patients with dental pulp disease is higher than young men.Chronic pulpitis is the main constant pulp disease in permanent teeth.The constituent ratio of different types of dental pulp disease changes when the gender is different,and retrograde pulpitis has a predilection to occur in men,chronic pulpitis has a predilection to occur in women.Dental pulp disease has a predilection to occur in the first permanent molar and the second permanent molars;In southwest medical university affiliated stomatological hospital,patients with dental pulp disease were mainly from urban area of luzhou city.Currently root canal treatment is the mainly treatment for dental pulp disease in clinical;The awareness of oral health and treatment need of this region's population remains to be strengthened,especially for male.
