Dentists’ Attitudes in Jordan towards the Shortened Dental Arch Concept: A Cross-Sectional Study

الملخص EN

Aims.

To assess the awareness, knowledge, attitudes, and application of the shortened dental arch (SDA) concept by dentists in Jordan.

Materials and Methods.

In this cross-sectional survey, a questionnaire was disseminated to a random sample of 150 dentists working in private practices, university hospitals, or governmental institutes.

The chi-square (X2) test was used to examine associations.

Results.

One hundred and six dentists responded (70.7% response rate).

Fifty-five were females.

82.1% were aware of the SDA concept.

The fewer the years of experience, the more likely the dentists were aware of the SDA concept (X2, P=0.024) and the more likely they learned about it through undergraduate education (X2, P<0.001).

In a hypothetical clinical situation of a patient >50 years of age with missing molar teeth, 45.3% agreed that the molars should be replaced, while 54.7% did not agree.

Improving mastication was the main reason for agreeing (81.6%), while having reduced functional benefit was the main reason for disagreeing (64.9%).

The treatment modality most commonly recommended was implants fixed partial dentures (84.9%).

Of those aware of SDA, 67.8% agreed it could have a useful place in treatment planning within Jordan.

Cost reduction for patients was the main reason for this answer, as reported by 51% of those who agreed.

26.4% did not apply SDA for any of their patients, while 50.6% applied it for <10% of their patients.

Conclusion.

The majority of the dentists was aware of the SDA concept and had a positive attitude towards it; however, few of them applied it in their practice.
