Children; Dental Trauma; Dental Caries; Non Vital Teeth; PrevalenceAbstract
Non vital teeth are irreversibly damaged to the pulp which may be associated with necrotic pulp, pulpless or
immature permanent teeth. A dead tooth can be differentiated with a decrease in lightlessness and it is more
saturated. Trauma, untreated dental cavities are the most common cause of non-vitality which gradually causes
infection and the tooth eventually dies. The aim of this study is to investigate the prevalence of non vital incisors
and molars in children. Data collection was done in a private dental university setting. 557 case records were
reviewed from which 70 patients were selected fulfilling the inclusion and exclusion criteria.The molars and
incisors of those patients were reviewed from records i.e 1120 teeth, from which 96 incisors and molars was
found non vital. The following parameters were evaluated based on the dental records : age, gender, non vital
molar or incisor and presence of pain or discolouration if any all those datas were gathered. Excel tabulation
and SPSS version 23 was used and data was subjected to analysis. Chi square test was done. The level of
significance set at p<0.05. The results proved that overall prevalence of non vital incisors and molars was 8.6%
.Male (75%) had a higher prevalence of non vital incisors and molars than females (25%). The prevalence of
non vital teeth among the children peaked at the age groups of 11-14 years. The most frequent associated non
vital teeth were found to be 11 and 21. Statistically significant differences between age groups and non vital
teeth showed a higher proportion of 11-14 years old patients were associated with non vital teeth than other age
groups (p<0.05). Within the limits of this study, overall prevalence of non vital incisors and molars in 8 to 18 year old children was 8.6% The highest prevalence of non-vital molars and incisors exhibited in males within the age group of 11-14 years. The most frequently associated non vital teeth were found to be 11 and 21. Male had greater prevalence of non vitality when compared with females. As most of the non vital teeth were found to be asymptomatic,there is a need for regular dental visits which may eliminate the future tooth loss in children
