The Effect of Maxilla Impacted Canine Positions on Root Resorption of Adjacent Teeth Using Cone-Beam Computed Tomography Imaging.

Objective: To determine the effect of the impacted position of the maxillary canine on the root resorption of the adjacent incisor using Cone-beam Computed Tomography (CBCT) imaging. Methods: This was an analytic quantitative study. The research sample determined CBCT images of treatment patients at the Orthodontic Specialist Policlinic in Dental Hospital of Airlangga University over a three-year period and secondary data taken from Pramita Laboratory. CBCT photos that met the inclusion criteria, including mesially impacted canine or close to central or lateral incisors with completely formed anatomy were then analyzed. Multiple linear regression was used to determine x-axis, y-axis, z-axis position of the impacted canine on the severity of root resorption of the adjacent incisor, and the effect of impacted canines on all axes simultaneously on the severity of root resorption of the adjacent incisors. Results: The position of the impacted canine in the x-axis and z-axis planes had a significant influence on the root resorption of the adjacent incisor. Meanwhile, impacted canine from the y-axis plane showed non-significant influence on the root resorption. Conclusion: The position of the impacted canine when viewed in all planes of the tooth axis has a significant effect on the severity of root resorption of the adjacent incisor.

A multidisciplinary approach of impacted and transposed maxillary canine: A case report.

The impacted and transposed teeth cause consequences in tooth eruption and movement, resulting in aesthetic and functional outcomes. A proper treatment plan with treatment duration and cost consideration is necessary to treat them. This study reported treatment for a 23-year-old male patient with impacted and transposed canine in maxilla using a multidisciplinary method between orthodontic and conservation. According to the anamnesis of the patient, his upper arch midline contained an extra tooth when he was a child. With the consideration of the duration and cost of treatment, the preferable and manageable treatment fell into the correction using a fixed orthodontic appliance with careful mechanics and enameloplasty to achieve the aesthetic and functional goal.

Correlation between vertical components and skeletal Class II malocclusion in ethnic Javanese.

INTRODUCTION: The dentoskeletal morphology of Class II malocclusion has been analyzed in several cephalometric investigations. It is crucially important to understand the vertical components in orthodontic treatment. Defining the facial type of an individual is an essential key to obtain an accurate orthodontic diagnosis. AIM: The aim of this study was to understand the correlation of vertical components in Class II skeletal malocclusion. MATERIALS AND METHODS: This is a observational descriptive study. This study used lateral cephalograms of Class II skeletal malocclusion from Universitas Airlangga Dental Hospital, between April 2015 and 2016. Cephalometric analysis was performed using digital software by a single examiner. This analysis measured gonial (Go), upper gonial (Go1), lower gonial (Go2), Yaxis-SN angle, the length of anterior face height, and posterior face height. The correlation between each variable was analyzed using the Pearson correlation test (P<0.01). RESULTS: There was a correlation between vertical components and Class II skeletal malocclusion. CONCLUSION: Vertical components were correlated with Class II skeletal malocclusion. The greater ANB angle will be followed by greater Go2, which worsens the condition of Class II skeletal malocclusion.
