Perth Glossary Of Dental Terms R to S


This is a glossary of terms for your information.

Aria Dental recommends that you understand dental terms and words that may be used in the course of dialogue with our Dentists and Dental Staff.

Please do not hesitate to seek further clarification, if necessary.

All our staff will be happy to assist in your understanding.


  • Re-implantation: The insertion and temporary fixation of partially or completely avulsed teeth resulting from traumatic injury.
  • Reline: The acrylic restoration of a denture base to compensate for bone loss.
  • Restoration: The replacement of a portion of a damaged tooth.
  • Retained Root: The partial root structure remaining in the jaw after extraction or fracture of a natural tooth.
  • Root: The tooth structure that connects the tooth to the jaw.
  • Root Canal Therapy: The process of removing the pulp of a tooth and filling it with an inert material.
  • Root Resection: The removal of a portion of diseased root structure, but retaining the remaining natural tooth.
  • Rubber Dam: A soft latex sheet used to isolate one or more teeth from contamination by oral fluids and to keep materials from falling to the back of the throat.


  • Saliva: A clear lubricating fluid in the mouth containing water, enzymes, bacteria, mucus, viruses, blood cells and undigested food particles.
  • Saliva Ejector: A suction tube placed in the mouth to remove saliva.
  • Salivary Glands: The glands located under the tongue and in cheeks that produce saliva.
  • Scaling and Root Planning (SRP): The meticulous removal of plaque and calculus from tooth surfaces.
  • Sealants: Thin resin material bonded in the pits and fissures of back teeth for the prevention of decay.
  • Secondary Dentine: Reparative tooth structure produced by the pulp in response to tooth irritation.
  • Sinus Grafting or Sinus Lift: Is surgery that adds bone to your upper jaw in the area of your molars and premolars. It is also known as sinus augmentation. The bone is added between your jaw and the maxillary sinuses, which are on either side of your nose.
  • Sinusitis: Inflammation of the sinus that may mimic dental pain.
  • Sleep Apnoea: The periodic interruption or delay in breathing during sleep. It is a serious medical disorder that has long term consequences and requires management.
  • Socket Preservation: Also known as alveolar ridge preservation (ARP), it is a procedure to reduce bone loss following tooth extraction. A bone grafting material or scaffold is placed in the socket of an extracted tooth at the time of extraction. The socket is then directly closed with stitches or covered with a non-resorbable or resorbable membrane and sutured.
    After extraction, jawbone has to be preserved to help keep the socket in its original shape. Without socket preservation, the bone quickly resorbs resulting in 30-60% loss in bone volume in the six months after dental extraction. The jawbone will never revert to its original shape once bone is lost and tissue contour has changed.
    The human body reduces the amount of bone that is not sufficiently used with a daily stress; without the strain stimulus, the jawbone behaves (with or without socket preservation) as if the space occupied by the tooth and periodontal ligament was empty.
  • Splint: The connection of two or more teeth so that they function as a stronger single structure.
  • Supernumerary Tooth: An extra tooth.
  • Suture: A stitch or stitches used by doctors and surgeons to hold tissue together.
