Bottom Line: The treatment time was recorded.Ninety-six teeth were treated with a magnifying loupe and 86 teeth were treated without a magnifying loupe.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.

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.

Mentions: The study was approved by the Institutional Review Board of the University of Hong Kong/Hospital Authority Hong Kong West Cluster (HKU UW 09–303) in Hong Kong and Peking University (PKU IRB 00001052–10071) in Beijing, China. Chinese patients who were generally healthy and required primary endodontic treatment via the HKU Health Service Dental Clinic in Hong Kong and the PKU School and Hospital of Stomatology Special Service Clinic in Beijing were invited to participate in the study. They were allocated systematically into 2 groups by the receptionists: endodontic treatment with loupes and endodontic treatment without loupes. Teeth with pulpotomies were not accepted, and at least half of the coronal structure had to remain. The protocol of the study was explained to participants and consent was obtained. Patients who had severe acute pulpitis with facial swelling or systemic infection, severe systemic disease, increased stress on the temporomandibular joint musculature, or increased psychological stress were excluded from this study (Figure 1).Figure 1
