Abstract

Background

Use of magnifying loupe may increase the efficiency of dental care. This clinical trial compared the time in performing non-surgical endodontic therapy with or without the use of a magnifying loupe.

Methods

Patients who required primary endodontic treatment in clinical trial centres at the University of Hong Kong (HKU) in Hong Kong and Peking University (PKU) in Beijing were invited to participate in this study. Two HKU dentists and 2 PKU dentists, forming 2 pairs of dentists with similar years of clinical experience, performed endodontic treatments according to the same procedures and used the same materials, either in single or multiple visits. They had no prior experience with the use of a magnifying loupe. One dentist from each pair was trained to use a magnifying loupe (x2.5). The treatment time was recorded.

Results

Eighty-four PKU patients with a mean age of 42.8 years and 98 HKU patients with a mean age of 46.0 years were recruited in this study. Ninety-six teeth were treated with a magnifying loupe and 86 teeth were treated without a magnifying loupe. The results showed that treatment time was not associated with age, gender, tooth vitality, or the presence of apical radiolucency or sinus tract. The results of ANCOVA revealed the treatment time was associated with the clinic (HKU or PKU), root canal system (single or multiple), presence of preoperative pain, treatment visit (single or multiple), the use of a magnifying loupe, and the experience of the operator.

Conclusion

In this study, the use of a magnifying loupe could significantly reduce the endodontic treatment time.
