Clinical Outcomes

The National Dental Centre Singapore is committed to delivering a high level of quality oral care to all its patients. It provides the full range of oral care services, for patients of all age groups. It also serves patients who may require special care for even the simplest procedures due to pre-existing medical consitions or other complicating factors which require care to be sited at a tertiary level. 

We track and measure clinical indicators for commonly performed dental procedures as part of an overall programme for managing clinical quality:

Unplanned Returns Following Impacted Teeth Surgeries

Impacted teeth sugery is the surgical removal of diseases of impacted teeth, a common procedure performed by the Department of Oral & Maxillofacial Surgery at the Ambulatory Surgery Centre, with the option of local or general anaesthesia.

Other than planned returns to the clinic to review healing and remove sutures, unscheduled returns can occur. Common reasons for these returns within 3 weeks of surgery include uncontrolled or prolonged pain, bleeding, infection or severe swelling. The percentage of unscheduled patient return is measured.

Unplanned Returns Following Fillings

Dental fillings are placed where there is tooth structure loss, mostly due to decay or external trauma. The fillings restore function, integrity and morphology of the missing tooth structure. Fillings can be indicated by dental surgeons for patients undergoing tertiary care as part of supportive treatment to restore overall oral health and function. The service is available at the General Practice Unit. The number of unplanned returns within 3 months following the placing of fillings is measured.

Peer Assessment Rating (PAR) Following Orthodontic Completion

The Department of Orthodontics specialises in the arrangement of teeth and the way teeth come together (occlusion). Orthodontic treatment aims at bringing teeth and jaws into a harmonious position with the face. This may improve the appearance, oral health and function.

Peer Assessment Rating (PAR) is an orthodontic index devised to assess the degree of improvement achieved from orthodontic treatment. Scores are assigned to various occlusal traits which make up a malocclusion. The scores are added up to provide a single summary score for all the occlusal anomalies associated with the malocclusion. This score provides an estimate of how far a case deviates from normal alignment and occlusion. The difference in scores between the pre-treatment and post-treatment cases reflects the degree of improvement as a result of treatment. A high standard of treatment is achieved if the mean percentage change in PAR score is high (greater than 70 per cent) (Richmond et al, 1992).
