• Research summary

  The study title is (Palatally impacted canine and maxillary arch width)

  Impacted maxillary canine is a commonly encountered problem in orthodontic practice, many authors have been interested to correlate the presence of maxillary canine impaction with certain causative factors.

  Maxillary arch width was investigated as a local factor which may cause palatal impaction of canines.

  It is difficult to reach to a conclusion regarding the association between maxillary arch width and the occurrence of palatal canine impaction, especially with the contradicting results of different studies which used different methodologies.

  Knowing the associated risk factors for the palatally impacted canine would facilitate early diagnosis and interception to prevent the occurrence of this type of impaction.

  Aims
  1-To measure the maxillary arch width in a group of patients with palatally impacted canines.

  2-To compare the maxillary arch width of patients with palatally impacted canines with a control group of patients without palatal canine impactions.

  Objectives
  To measure the maxillary inter-premolars and inter-molars widths from pre-treatment study models of patients with palatally impacted canines and from pre-treatment study models of patients without palatally impacted canines.

  Method

  Study design
  Case-control, retrospective study of records.

  Subjects
  The study group will include pre-treatment records of 30 patients with palatal canine impaction and pre-treatment records of 30 patients with normally erupted maxillary canines. These records are the available study models (a plaster replica of the teeth) and dental radiographs for each patient in the study.

  The sample will be randomly selected from the available pre-treatment records of patients who have received orthodontic treatment at Countess of Chester hospital. The age of patients in both groups will range from 14 to 16 at the time of taking their records.

  Procedure
  I will measure the maxillary transverse dimension (the width of the maxillary arch) by measuring the distance between the maxillary first premolars and maxillary first molars on both sides of the arch
