Introduction・Purpose: We conducted qualitative research to explore the psychosocial processes by which dental trainees overcome difficulties during clinical training. Our focus was on their resilience.　Methods: Semi-structured interviews with nine trainee dentists were conducted. For the data analysis, we used Modified Grounded Theory Approach.　Results: The three factors, namely, “relationships with others” , “inner strengths” , and “acting autonomously” , contributed to the processes by which negative effects of trainee dentists changed into positive ones.　Discussion: It was suggested that these factors could provide clues to understanding the psychological burden of dental trainees and how to support them in gaining self-confidence.
