The purpose of this study is to see whether extraction of the primary canine tooth or extraction of both the primary canine - and the primary first molar tooth is most effective in the treatment of palatally ectopic canine teeth in the maxilla. In addition the study will also measure pain and discomfort in relation to these two treatment alternatives.
1. Evaluate the effectiveness of concomitant extraction of the maxillary deciduous canine and maxillary deciduous first molar as compared to extraction of the deciduous maxillary canine only as an interceptive measure for improving the eruption path of ectopic maxillary canines.
2. Evaluate whether there is a difference in the use of analgesics, pain and discomfort between the two treatment groups in 1.
After informed consent patients will randomly be assigned to one of two groups. Group1: Extraction of the deciduous canine only Group 2: Extraction of both the deciduous canine and the deciduous first molar
Randomization The block randomization method will be used. Block sizes will randomly vary from 2, 4, 6 and 8. Blocks will be generated from free software at http://www.randomization.com . Allocation concealment is done by enclosing assignments into sequentially numbered envelopes. Envelopes that will have to be torn to open will be used. The randomization process will be done by a staff member at TkNN that is not involved in the trial.
Prior to extractions topical anesthetics will be given for two minutes, before the buccal and palatal infiltration of local anesthetic (1,8 ml dose, 20mg/ml lidocain with 12,5 g/ml epinephrine).
Patients and parents will be given oral postoperative information, including a recommendation to use non-prescription analgesics at their own discretion.
Clinical and Radiographic controls and evaluation:
Patients will be controlled clinically and radiographically (DPT) after 6 and 12 months. If improvement is not detectable after 12 months, alternative treatment will be suggested (surgical exposure, fixed orthodontic appliances, extractions). All cases which do not need alternative approaches will be followed until the tooth is erupted in the mouth.
Sector, alpha angle and d-distance will be measured on DPT-images
Dental anxiety Before any extractions are performed each patient will answer the modified dental anxiety scale (MDAS).
Pain and discomfort When the patients have performed their extractions they will receive two questionnaires, regarding pain and discomfort and use of analgesics, to fulfill at home and return by mail. The first part shall be answered the first evening as the extraction was performed and the second part should be answered one week post extraction.
Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

The pathologic wearing away of the tooth substance by brushing, bruxism, clenching, and other mechanical causes. It is differentiated from TOOTH ATTRITION in that this type of wearing away is the result of tooth-to-tooth contact, as in mastication, occurring only on the occlusal, incisal, and proximal surfaces. It differs also from TOOTH EROSION, the progressive loss of the hard substance of a tooth by chemical processes not involving bacterial action. (From Jablonski, Dictionary of Dentistry, 1992, p2)
The wearing away of a tooth as a result of tooth-to-tooth contact, as in mastication, occurring only on the occlusal, incisal, and proximal surfaces. It is chiefly associated with aging. It is differentiated from TOOTH ABRASION (the pathologic wearing away of the tooth substance by friction, as brushing, bruxism, clenching, and other mechanical causes) and from TOOTH EROSION (the loss of substance caused by chemical action without bacterial action).
