Brief Summary

This study was conducted to compare the periodontal health of labially and palatally impacted maxillary canines with similar mesio-distal displacement, perpendicular distance, and angulation, and to compare them with the contralateral canines that served as control teeth. Two null hypothesis were tested: (1) there are no differences in attached and keratinized gingival widths and gingival thickness between impacted teeth and controls, and (2) there are no differences in attached and keratinized gingival widths and gingival thickness of labially and palatally impacted canines.

Conditions

Impacted Canines; Orthodontic Treatment; Gingival Thickness

Keywords

Impacted Canine; Closed Eruption Technique; Gingival Thickness; Keratinized Gingival Width; Attached Gingival Width

Outcome Measures

Primary Outcomes (1)

• Gingival Thickness measurement (mm)

  The gingival thicknesses of the impacted canines and controls measured along the long axis of the midbuccal surfaces of teeth under topical anaesthesia at two points: apical to the free gingival margin and coronal to the mucogingival junction. A 15-mm endodontic spreader was perpendicularly positioned to the long axis of the measurement points and gently inserted into the soft tissue until feeling the resistance of alveolar bone. Then, the endodontic spreader was carefully removed and the penetration depth between the tip of the endodontic spreader and silicon stopper was registered using a digital caliper with 0.01-mm sensivity

  6 months after the completion of orthodontic treatment

Secondary Outcomes (6)

• keratinized gingival width measurement (mm)

  6 months after the completion of orthodontic treatment

• attached gingival width measurement (mm)

  6 months after the completion of orthodontic treatment

• plaque index score (0-3)

  6 months after the completion of orthodontic treatment

• gingival index score (0-3)

  6 months after the completion of orthodontic treatment

• gingival bleeding index score (percentage)

Study Arms (2)

unilateral labially impacted maxillary canines

ACTIVE COMPARATOR

Distalization of the maxillary molars and/or protrusion of the maxillary and mandibular incisors made for creating sufficient space for impacted maxillary canines. After sufficient space for impacted maxillary permanent canine was obtained combine surgical-orthodontic treatment was performed via closed eruption technique. When the crown of the maxillary impacted canine was fully visible in the mouth, its bracket was inserted, and aligned within the dental arch. Posttreatment plaque index, gingival index, gingival bleeding index, probing depth, keratinized and attached gingival width and gingival thickness measurements of the impacted canines and controls were performed. The periodontal health of labially impacted maxillary canines compared with the contralateral canines that served as control teeth.

Procedure: closed eruption technique

Interventions

closed eruption technique PROCEDURE

The impacted teeth treated with closed eruption technique firstly. Orthodontic traction started a week later the sutures were removed. When the crown of the maxillary impacted canine was fully visible in the mouth, its bracket was inserted, and aligned within the dental arch using double-arch technique. Posttreatment plaque index, gingival index, gingival bleeding index, probing depth, and keratinized and attached gingival width and gingival thickness measurements of the impacted canines and controls were performed. The measurements compared with the contralateral canines that served as control teeth.
