Abstract
Introduction: Discoloured anterior teeth is always a reason for the development of an
inferiority complex when esthetics is considered as a single discoloured tooth stands out from
the rest, drawing more attention towards it. Hence, bleaching has become one of the most
desired treatments in dentistry. However, there seems to be a lack in studies which focus on
factors like number of visits, preoperative shade in determining the rate of success of bleaching
procedures. The aim of this study is to analyse how the number of visits, type of agents used
and the preoperative shade determines colour change in upper anteriors undergoing non vital
bleaching.
Materials and methods: This retrospective study was done by surveying the data of patients
who underwent non vital bleaching in a university dental hospital. Data like age, gender,
preoperative shade, number of visits, type of agents used during non vital bleaching were
collected. The collected data was then tabularised and imported to SPSS Version 23 for
statistical analysis. Chi Square test was used to find any association between comparative
variables.
Results: Males were the most common gender to undergo non vital bleaching, sodium
perborate was the most commonly used bleaching agent and older patients needed more visits
to achieve a satisfactory result (p-0.05). The most common pre-operative shade was A4.
Conclusion: Males were the most common gender to undergo non vital bleaching. The most
common age group to undergo non vital bleaching is 15-22 year olds. There is no correlation
between age, gender and number of visits with postoperative colour change
