Patients' perspective on the inclusion of intraoral scanners in routine oral examination: a clinical perception study

The purpose of the present study was to investigate how integrating intraoral scanners (IOSs) into routine oral diagnosis affects patient-clinician communication as well as patient perceptions and preferences, offering valuable insights into the patient experience and utility of IOSs in clinical practice.

A restorative dentistry specialist conducted intraoral examinations on 300 patients, initially using conventional techniques and radiographs, followed by a 3D intraoral scanner (iTero Element 2). The patients' existing oral issues and treatment plans were initially expressed verbally, and then repeated using the 3D intraoral scan. Subsequently, the patients were requested to respond to an 11-question survey, aimed at assessing both modes of examination and communication. Statistical analysis employed the Wilcoxon test to compare the patients' experiences on the same topic before and after the examination with the IOSs, considering a significance level of P 0.05.

The majority (38%) of participants were 25 to 35 years of age (52% females; 48% males). Statistically, patients found it more comprehensible to visualize existing oral issues through 3D intraoral scans than through a verbal explanation (P = 0.000). Also, patients understood oral hygiene recommendations better when explained by dentists through the use of intraoral scans (P = 0.000). The vast majority of participants (94%) indicated that being examined with an IOS motivated them to obtain treatment, while 6% remained undecided. All of the participants thought that intraoral scanning should be included in routine oral examination.

Intraoral 3D scans enhance patient understanding and communication during routine oral examination and participants showed a high preference for their usage. However, more research is needed to replace conventional diagnostic methods.
