Summary Objectives The aim of this retrospective study was to assess in maxillary canine impaction cases both the prevalence of root resorption of adjacent teeth among untreated children and adolescents, and its associated risk factors. Subjects and methods Sixty subjects (mean age 12.2 years; SD 1.9; range 8–17 years) with 83 displaced maxillary canines and without any past or ongoing orthodontic treatment were included in this study. The presence of root resorption was evaluated on images from a single cone beam computed tomography (CBCT) unit. Potential risk factors were measured on the CBCT images and on panoramic reconstructions of the 3D data sets. The sample was characterized by descriptive statistics and multiple logistic regressions were performed to predict root resorption. Results Root resorption of at least one adjacent tooth was detected in 67.5 per cent of the affected quadrants. It was found that 55.7 per cent of the lateral incisors, 8.4 per cent of the central incisors, and 19.5 per cent of first premolars were resorbed. Of the detected resorptions, 71.7 per cent were considered slight, 14.9 per cent moderate, and 13.4 per cent severe. Contact between the displaced canine(s) and the adjacent teeth roots was the only identified statistically significant risk factor, all teeth being considered (odds ratio [OR] = 18.7, 95% confidence interval: 2.26–756, P < 0.01). An enlarged canine dental follicle, a peg upper lateral, or an upper lateral agenesis were not significantly associated with root resorption of adjacent teeth, nor were age nor gender. Conclusions Root resorption of adjacent teeth was detected in more than two-thirds of a sample of sixty untreated children and adolescents.

ntroduction The aim of this study was to evaluate cases of impacted maxillary canines (IMC) using cone beam tomography (CBCT) and panoramic images in an attempt to assess if panoramic radiographs can provide information compatible with CBCT results regarding canine position and root resorption. Methodology Fifty-six impacted maxillary canines from 48 patients were radiographically evaluated. The positions of the canine teeth were classified by Sector localization on panoramic radiographs and the same teeth were also analyzed by KPG on CBCT. Root resorptions in maxillary lateral incisors were also evaluated on CBCT. The relationships between panoramic and CBCT findings were compared by Chi-square test and Fischer’s exact test. Results Statistically significant correlations were found between panoramic Sectors and KPG indexes (p<0.001). KPG index values of 1, 3 and 4 corresponded to the panoramic Sectors 1, 4 and 5, respectively; but KPG index 2 matched the panoramic Sectors 3 and more often 2. Mid-alveolar impaction generally coincided with score 1 for both KPG index and panoramic Sector. In palatally IMC, this score value was generally 2 or 3 for the KPG index and 4 for the panoramic Sector (p≤0.001). Root resorptions in maxillary lateral incisors showed significant differences according to Sector localization and KPG index (p<0.05), namely they coincided with 2 and 3 in Sector evaluation and 2, 3 and 4 in KPG index. Conclusions Sector location on OPG is found to be related to KPG index on CBCT, and it can help evaluate mainly certain positions of impacted canines; thus, unnecessary CBCT scans are not requested.

Extraction Therapy

Background and Objectives The average orthodontic treatment time for extraction therapy is 31 months. One of the main disadvantages of orthodontic treatment is time. Alveolar corticotomies have been used in conjunction with orthodontics to reduce the treatment time by increasing the rate of tooth movement. Concerns about the possible risks of corticotomy procedure have led to the modification of this technique. Germeç et al. reported a case treated by their modified corticotomy technique and noted reduced treatment time without any adverse effects on the periodontium and the vitality of teeth with their new conservative corticotomy technique. This study was undertaken to clinically evaluate the efficacy of the aforesaid technique. Materials and Methods A split-mouth study design was carried out to compare the rate of maxillary canine movement with and without modified corticotomy facilitated orthodontic treatment in 10 patients requiring maxillary first premolar extractions. The modified corticotomy procedure was performed on the maxillary arch unilaterally. The upper arch was immediately activated bilaterally after surgical procedure using equal orthodontic forces for retraction of the maxillary canines. The amount of tooth movement was recorded at an interval of every month till the completion of canine retraction. The rate of canine movement on experimental and control site was compared. The patients were followed for 6 months to check the occurrence of undesired effects such as root resorption, periodontal damage and loss of vitality of teeth on the experimental side. Results Higher mean velocity was observed in canines with modified corticotomy facilitated retraction compared to conventionally retracted canines; with the difference in mean velocity between the two groups was found to be clinically significant as well as statistically significant (P < 0.001). Interpretation and Conclusion The results suggested that modified corticotomy technique serves as an effective and safe way to accelerate orthodontic tooth movement, without adversely affecting the periodontium, root resorption, and the vitality of the teeth, as concluded by clinical and radiographic examination.

Maxillary canines are the most commonly impacted teeth, second only to third molars. Various treatment methods may be used to recover impacted maxillary canines. This is a report of a 14-year-old girl with a severely malpositioned impacted right maxillary canine which accompanied severe root resorption of adjacent tooth, treated by autotransplantation with a computer aided rapid prototyping model as a surgical guide. This case report demonstrates that autotransplantation can be a reliable treatment alternative, in cases with a severely malpositioned impacted canine, providing acceptable prognosis.

This study aimed to identify the location of root resorption in relation to an impacted maxillary canine and grade its severity using cone-beam computed tomography (CBCT) in the Saudi Arabian population. Materials and Methods: CBCT scans of 169 patients with maxillary canine impaction were evaluated. The location and the severity of root resorption of the affected tooth in relation to the impacted maxillary canine were recorded for each patient. Results: a total 204 impacted maxillary canines caused root resorption in 218 adjacent teeth. Maximum root resorption was present in 63.3% of the apical one-third of the root and 37.6% of the palatal surfaces. There was mild root resorption in 55%, moderate in 10% and severe in 35%. There was no statistically significant difference between the gender, age, type of impaction, side of impaction, and the number, location, or degree of root resorption. Multiple logistic regression models showed significant association (p = 0.024) between gender, type of impaction, and root resorption. A significant correlation was found between the level and the surface of the root resorption (p = 0.018). Conclusion: In the Saudi population, apical one-third root levels and palatal surfaces were primarily involved in root resorption caused by impacted canines. The females with bilateral canine impaction were more likely affected by root resorption.

Maxillary Impacted Canine

Background & Objective: Impacted teeth are one of the most common reasons for visit- ing dentists and maxillofacial surgeons. During clinical and radiographic examinations and evalu- ations, the dentist sometimes realizes that the patient’s problem is due to the impaction of one or more teeth. Therefore, it is necessary for every dentist to make the necessary and correct decision for the treatment of such teeth. One of the best ways to diagnose impacted teeth is first of all the absence of that tooth in the desired location and clinical evaluation of the patient and secondly to check the radiographic view of the desired area. Impacted teeth can be the source of many prob- lems for various reasons, so in most cases, their extraction is recommended. Knowing how to place the impacted tooth and determining its type and other characteristics of the impaction can help the dentist in choosing the appropriate treatment-surgical method and also prevent complications during surgery. Proper and timely diagnosis of impaction as well as determining its position (buc- cal-palatal-intermediate) in the jawbone can reduce damage to adjacent structures and also affect the treatment plan. Because accurate detection of impacted tooth positions is possible with radiog- raphy, the most accurate radiograph to examine the impacted tooth is cbct images. Therefore, due to possible occlusion injuries and the effect of occlusion pattern on the treatment of these teeth, it is important to study the types of impaction patterns. Therefore, this study was presented with the aim of investigating the impaction pattern of maxillary canine teeth in Ardabil with cbct archive. Materials and Methods: In this descriptive cross-sectional study, CBCT images of 239 patients who met the inclusion criteria were evaluated. Due to the lack of statistics, due to the lack of statistics of maxillary impacted canine teeth in Ardabil, the counting method was used for sampling and stereotypes were identified as maxillary impacted canine teeth as the sample size. The obtained data were analyzed in SPSS24 software. Results: Among the impacted canine teeth studied, 63.2% had palatal, 17.5% buccal and 19.3% had intermediate pattern. Also, 11.2% had damage to adjacent structures and 88.8% had no damage to adjacent structures. Among the types of damage to adjacent structures, 46.9% caused root re- sorption of the first premolars, 34.5% caused root canal resorption, and 18.6% had other damage to adjacent structures. Of these, 50.4% had root curvature and 49.6% had no root curvature, of which 12.1% had severe curvature, 38.7% had mild curvature and 49.2% had severe curvature. Also, the average angle of the incised canine to the lateral incisor was 41.7%. 9% of impacted canine teeth had a root resorption of lateral incisors and 9% did not have a root resorption of lateral incisors. Conclusion: Dentists should treat cases such as maxillary latent canine such as: Examine the occlusion pattern, angle to adjacent teeth, damage to adjacent structures, curvature of the incised canine root, and root resorption of adjacent teeth.

Abstract Background The present study aimed to report a technically improved operation on the surgical exposure of labially impacted maxillary canine, elaborating the management of soft tissue to achieve better aesthetic results, and post-treatment periodontal health. Methods Patients sought orthodontic treatment with unilateral labially impacted maxillary canines were selected in this study. The impacted teeth were assigned to the experimental group and contralateral unimpacted canines were assigned to the control group. The impacted canines were surgically exposed with dissected dental follicle (DF) stitching to muscle and mucosa surrounding the crowns. The gingival index (GI), probing depth (PD), the width of the keratinized gingiva (WKG), gingival scars (GS), bone loss (BL), and apical root resorption (ARR) were recorded after the removal of the fixed appliance. A two-sample t-test was used for independent samples for parametric variables. Results A total of 24 patients with unilateral maxillary canine impaction were successfully treated. The outcomes of GI, WKG, GS, BL, and ARR did not indicate statistical significance between the experimental group and the control group. Conclusions The preservation of DF promotes soft tissue management in combined surgical and orthodontic treatment of labially impacted maxillary canine to achieve better periodontal status.
