The application of toothguide training box using in dental color choice training

Abstract

Objective To explore the law of tooth color training and find its reasonable training methods.Methods 20 eight-year program students studying in Peking University,School of Stomatology were chosen to participate in the toothguide training process using Toothguide Training Box (TTB) for 9weeks.Each student must take part in 4 times of tooth shade matching tests (Under standard light source,middle color included).The tooth shade matching tests occur at the beginning of their training,3 weeks after their training,6 week after their training and the end of their training.The correct rate of the standard color,non-standard color (middle color),and the correct rate in all were calculated for each time of shade matching tests.The data was analyzed with SPSS 13.0 software.Results After 3 weeks training,the total correct rate and the correct rate of standard color were significant differences (P＜0.01) withthe baseline results; after6 weeks training,the correct rateof non-standard color werestatisticallydifferent (P ＜ 0.05)with the after 3 weeks training results; both after 6 weeks and 9 weeks training,the three correct rates were statistically different (P＜0.05)with the baseline.Conclusions Using both TTB and tooth shade guide (including middle color) as a combination of teaching tool,can not only improve the standard color matching ability,but also can take the knowledge of the middle color training into account.While using the TTB training system,the training progress should be last more than six weeks.
