The assesment of pattern of maxillary canine impaction in the Ardabil city

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.

Gray value measurement for the evaluation of local alveolar bone density around impacted maxillary canine teeth using cone beam computed tomography.

Background To investigate whether any relationship between local alveolar bone density and maxillary canine impaction using gray values from cone beam computed tomography.Material and Methods The cone beam computed tomography images of 151 patients were retrospectively evaluated. Maxillary canine was defined as an impacted tooth when root formation was complete and the patient’s age older than 13 or the other side of the maxillary canine has completely erupted. Similarly, complete eruption was defined as the tooth in its expected occlusion and position. Using the cone beam computed tomography software, the region of interest which was 5 mm2 in area, was placed in the trabecular bone on cross sectional cone beam computed tomography images and the gray value measurements were recorded. After measuring the gray values of all the teeth, the images were grouped according to the field of view size. Comparison of the gray values of impacted and non-impacted teeth was made between images with the same field of view size.Results A total of 151 patients, 101 (66.9%) female and 50 (33.1%) male, were included in the study. The mean age of the patients was 24.94 ±13.9. In images with a 40X40 field of view, the gray values of the impacted canine teeth were higher than the gray values of the non-impacted ones and statistically significant difference was found between them (p=0.003). However no statistically significant difference was found between the gray values of impacted and non-impacted canine teeth in 60x60 and 100x50 field of view (p=0.197, p=0.170, respectively).Conclusions We suggest using the smallest field of view size when evaluating bone density using gray values from cone beam computed tomography images and we support the idea that the local increased bone density may influence on impaction. Key words:Cone-beam computed tomography, tooth, impacted, bone density, maxilla, image processing, computer-assisted.

Objectives: To assess the difficulty level of dental impaction treatment. This article discusses the problem of odontomy treatment based on the classification of maxillary canine impaction through panoramic radiograph examination and CBCT.
 Literature Review: Impacted tooth is pathological where the tooth fails to reach its normal functional position. Impaired maxillary canine second order placement after impact of third molars. The location of impacted jaw canine teeth most often occurs in the palatal region with a horizontal position according to the maxillary sinus and nasal cavity so that complications are required during odontomy. 
 Conclusion: Based on this literature study, classification on impacted maxillary canine teeth has been developed based on panoramic (2D) and CBCT (3D) radiography, so thus resulting in a complete classification of impacted maxillary canine teeth and can be used as a predictor of the difficulty level of maxillary canine tooth impaction treatment.

Radiographic Features and Treatment Strategies of Impacted Maxillary Canines

Objective: Treatment of impacted maxillary canines is essential, both aesthetically and functionally. This study aims to define the radiographic features of maxillary impacted canines, evaluate treatment options, and to detect related pathologies.Materials and Methods: In this retrospective study, orthopantomographs, treatment options, and demographic features of the patients were analyzed. Impacted maxillary canines were classified according to the study of Yamamoto et al. According to this classification, maxillary canines are evaluated under seven types according to the occlusal plane and their relative location to adjacent teeth. Moreover, the pathologies around impacted canines were detected via panoramic radiographies.Results: 323 impacted maxillary canines of 270 patients were analyzed. Two hundred fifteen of these teeth (66.6%) belonged to females, while the rest 108 (33.4%) belonged to males. It was observed that impacted maxillary canines were bilateral in 53 patients and unilateral in 217 patients. In the classification based on direction and position of impacted maxillary canines, the highest rates was Type 2 (55.42%) which was followed by Type 4 (26.93%), Type 1 (12.38%), Type 7 (2.79%), Type 3 (1.86%) and Type 5 (0.62%), respectively. Twenty-eight patients with cystic lesion related to impacted maxillary canines were detected. Impacted maxillary canines concomitant with odontoma was detected in 4 patients. In 52 of the patients, it was detected that maxilla was edentulous except for the impacted canines, and the extractions of impacted canine teeth were due to prosthetic reasons. Thirty impacted maxillary canines of 24 patients (n=30, 9.28%) were placed buttons for orthodontic maintenance, while surgical tooth extraction was preferred as a treatment option in other patients.Conclusions: Orthodontic, surgical treatments or combinations may be preferred depending on the impact level of the canine. Early diagnosis and correct orientation of the patient is essential for the success of the treatment.

Impacted maxillary canines: a five year retrospective audit of the correlates for successful outcome of surgical exposures in a district general hospital

Introduction The incidence of impacted canine teeth in the adult permanent dentition remains estimated between 1-3%. Ideally, impacted canines are prevented using interceptive orthodontics, however surgical intervention is sometimes necessary. Two techniques for exposing canines are routinely used in the U.K: the closed and the open technique.

Is the maxillary sinus volume affected by concha bullosa, nasal septal deviation, and impacted teeth? A CBCT study.

Various mechanisms play an important role in the growth of maxillary sinus cavities. The purpose of this study was to investigate the correlations ofmaxillary sinusvolume (MSV)with nasal septal deviation (NSD),conchabullosa (CB) and impacted teeth using cone-beam computed tomography (CBCT) images. From 55 patients, a total of 110 maxillary sinus images were obtained and examined. Data including age, gender, impacted third molar, canine teeth, NSD, and CB were examined. MSV was measured using the MIMICS software (Materialise HQ Technologielaan, Leuven, Belgium). All statistical analyses were performed using the SPSS (Statistical Package for Social Sciences, version 21) software and p values < 0.05 were considered to indicate statistical significance. Mean volume of the right maxillary sinus was 13.566 cm3, while the left was 13.882 cm3. The rate of patients with right and left impacted third molar teeth was 49.1% and 47.3%, respectively. The rate of right and left impacted canines was 1.8% and 5.5%, respectively. NSD was found in 56.4% of CBCT examinations and right and left CB were observed in 30.9% and 32.7% of the patients' examinations, respectively. Males had a significantly higher mean sinus volume than females for both sides (p < 0.05). There were no significant correlations between MSV and age (p > 0.05). No significant differences were found between MSV and impacted teeth, NSD and CB (p > 0.05). NSD, CB, impacted teeth, and age were not found to be related to MSV. Gender had an effect on MSV and males had higher mean sinus volume than females.

YouTube video analysis as a source of information for patients on impacted canine

To investigate video content on YouTube™ related to impacted canine and impacted canine surgery. In this cross-sectional study, the term "impacted canine tooth" was searched on YouTube™. After excluding duplicates, irrelevant videos, non-English-language videos, no audio-no video contents, sixty-one videos were independently examined by 3 reviewers. Videos were categorized as "not useful", "slightly useful", "moderately useful", and "very useful" by using an 8-point score list for evaluating the value of the videos in providing patients information about impacted canine teeth and surgery. Chi-square test was performed for categorical variables and differences between groups were compared with Kruskal-Wallis. Correlations were analysed using Spearman test. Statistical significance was set P<0.05. Most of the videos, 42.6%, n=26 were uploaded by healthcare professionals [dentists, orthodontists, surgeons] and 29,5%, n=18 were uploaded by laypersons for sharing personal experiences. There were 3 [4.9%] not useful videos, 15 [24.5%] slightly useful videos, 27 [44.2%] moderately useful videos, and 16 [26.2%] very useful videos. There was no significant difference between the viewing rate according to the source of upload [P=0.398>0.05]. There was a significant difference between the interaction index according to the source of upload. This difference was in the laypersons and the others [.033<05]. Healthcare specialists should be aware of the content of the video-sharing platforms and direct their patients to correct and reliable e-information resources.

Adenomatoid Odontogenic Tumor – A Case Report

Adenomatoid odontogenic tumor, a benign tumor of odontogenic origin has known for many years. Only few case reports have been published in the literatute and hence considered to be an uncommon tumor. The lesion has been called by various names as it has exhibited in various clinical and histological patterns for which the origin and histogenesis still remains uncertain. Here, we report a case of 18 year old female patient who came to us with a complain of swelling in the upper anterior tooth region and radiographically showing an Extrafollicular radiolucency adjacent to the crown of an impacted canine tooth.

Health of periodontal tissues and resorption status after orthodontic treatment of impacted maxillary canines.

The aim of the present study was to evaluate the changes of incisor root resorption associated with impacted maxillary canines and health of periodontal tissues around maxillary canines erupted with orthodontic treatment. Twenty patients with a unilateral palatally impacted maxillary canine were included in the study. Cone-beam computed tomography images taken before and after orthodontic treatment were compared with the contralateral canines serving as control teeth. Root resorption was present in 10% of central and 40% of lateral incisors before treatment. After treatment, the incidence of resorption decreased. The thickness of the buccal bone surrounding the impacted canines was similar to that surrounding the contralateral canines, except in the apical area. Periodontal pocket depth and alveolar bone loss were greater for the impacted canine teeth than for the contralateral canines. Incisor root resorption associated with impacted canine teeth showed signs of repair after orthodontic treatment. Slight differences related to periodontal health were found between the previously impacted teeth and contralateral canine teeth.

Maxillary canine impaction to treat or not

Management of impacted canine teeth requires early diagnosis and interception of the clinical situation. Various treatment modalities are available in literature, and the clinical situation may demand interdisciplinary approach. The treatment options should be time- and cost-effective with promising result both functionally and esthetically. This review article is an overview of etiology, diagnosis, and treatment modalities for the management of impacted canine.

Success of closed exposure for impacted upper canine teeth combined with orthodontic traction: A retrospective study

Background: Impacted permanent canine teeth occur in 2% of the population. The incidence of maxillary impaction is 85%, with 8% occurring bilaterally. The incidence of palatal impaction is higher than to buccal impaction.

Ectopic Erupted Teeth: A Case Report

Introduction: Although ectopic eruptions of teeth into the nasal cavity have been previously reported, the eruption of a tooth into the turbinates of the nose is quite rare. This report describes a case in which a tooth ectopically erupted into the inferior turbinate of the nose. Signs and symptoms of the occurrence, as well as its diagnosis and treatment, are also delineated in this case report. Case Presentation: A 32-year-old man with swelling in the left paranasal area of the face was referred to the department of Oral and maxillofacial surgery for diagnosis and treatment. A diagnostic workup resulted in the diagnosis of an ectopic tooth eruption. The tooth was removed via the use of a transoral approach and without any complications. Conclusions: This case report alerts surgeons to consider the possibility of an eruption of a tooth into the nasal cavity or inferior turbinate of the nose when panoramic radiography reveals an impacted canine tooth located high in the maxilla.

Correction of severe deep bite and gummy smile using mini-screw anchorage: A case report

The patient was a 23-year-old girl who had an Angle Class II Division 1 malocclusion, severe overjet, and deep bite with a gummy smile. She had both impacted mandibular canine teeth. The objectives were to correct deep bite, gummy smile, accentuated overjet, alignment of impacted canine and to achieve adequate overbite and overjet. The treatment involved extraction of maxillary first premolars proceeding with retraction and intrusion of the upper anterior teeth with mini-screw implants as the orthodontic anchorage. After treatment, adequate overbite and overjet and a satisfactory maxillary gingival exposure in the smile were obtained. The mini-screw implant anchorage method is useful for correction of severe overjet and a deep bite with a gummy smile.

Location and severity of root resorption related to impacted maxillary canines: a cone beam computed tomography (CBCT) evaluation

Abstract Background The present investigation was designed to determine the location and severity of root resorption associated with impacted maxillary canine teeth using cone beam computed tomography (CBCT). A secondary aim was to identify possible influencing factors. Methods The radiological reports of 183 patients, radiographed with a small-volume CBCT focussed on the impacted maxillary canine teeth, were assessed. Eighty-five patients had resorption associated with the impaction. The CBCT image datasets were viewed to determine the location and severity of the lesions. Results A total of 110 impacted maxillary canine teeth resorbed 120 adjacent teeth, including 14 premolars and one permanent molar. The apical third and palatal surface were commonly involved. Fifty per cent of the resorptive lesions were mild, 20% moderate and 30% severe. There was no significant relation between age or gender on the number, location or severity of resorption. There was a statistically significant correlation between the number of impacted canine teeth and the number of teeth resorbed, as well as the tooth type and the surface involved in the resorption. Conclusions All root levels and surfaces of teeth associated with impacted maxillary canine teeth can be resorbed to different levels of severity. Neither age nor gender influences the number, location or severity of the resorption.

Orthodontic camouflage management of a class II malocclusion with excessive overjet- A case report

In orthodontic practice various treatment modalities have been presented for the treatment for the class II, div 1malocclusions. Recently a large number of young adults have been seeking shorter, cost effective and a non surgical correction of Class II malocclusions and they accept dental camouflage as a treatment option to mask the skeletal discrepancy .This case report presents one such case, a 15years old growing male who has Class II div I malocclusion with sever maxillary incisor proclination, convex profile ,high mandibular plane angle, incompetent lips, increased overjet&amp; overbite, over retained upper left deciduous canine ,impacted upper left canine and a supernumerary tooth in canine region. We considered the camouflage treatment by extracting the upper right first premolar, left impacted canine, deciduous canine and supernumerary tooth. Following the treatment, a satisfactory result was achieved with an ideal, static and a functional occlusion, facial profile, acceptable smile, competent lip and stable treatment results.

The management of palatally displaced maxillary canines: Considerations and challenges

This article opens with a recognition that ectopic maxillary canines may lead to frank impactions requiring a coordinated and multidisciplinary approach to their surgical/orthodontic management and the potential benefit of managing canine ectopia, particularly palatally displaced canines, more conservatively in their pre-eruptive ectopic positions in an effort to avoid impaction. The prevalence of palatally displaced canines (PDC) in various populations and corroborating as well as competing or conflicting opinions of etiology are briefly reviewed. Some of the traditional as well as relatively newer strategies and associated investigations of managing pre-eruptive palatally displaced maxillary canines are discussed, and the imaging techniques utilized to identify and locate ectopic maxillary canines are also discussed. Early detection of ectopic canines must include at the very least panoramic and/or periapical radiographs as part of any mixed dentition orthodontic examination and assessment. The sometimes unpredictable continued path of the ectopic maxillary canine poses clinical and ethical issues to the clinician when developing treatment strategies as part of any overall orthodontic treatment plan for young patients presenting with maxillary canine ectopia. The need for more thoughtful and carefully designed randomized clinical trials with a greater emphasis on subject sample scrutiny is strongly recommended to add much needed clarity to the clinical management of ectopic maxillary canines.

Bilateral Dentigerous Cysts in a Dog

Dentigerous cysts are infrequently seen in veterinary medicine, but the consequences of an undiagnosed dentigerous cyst can be severe. Dentigerous cysts, that can be sub-classified as eruption or follicular, are a type of benign odontogenic cyst. They can cause significant bony and dental destruction associated with expansion if they remain undiagnosed for a period of time. Dentigerous cysts are secondary to embedded or impacted teeth, however not every impacted tooth subsequently forms a dentigerous cyst. Intraoral dental radiographs are necessary to differentiate a missing tooth from an impacted tooth. This case demonstrates the successful surgical management of a dog with bilateral impacted mandibular canine teeth, with secondary dentigerous cyst formation.

Management of bilateral impacted upper canines by single tooth dento-osseous osteotomy

When it is difficult to treat impacted teeth with orthodontic traction, surgical techniques including intentional luxation, autografts and distraction osteogenesis may be performed. However, these techniques are associated with problems such as root resorption, gingival recession and pulp circulatory disorders after extrusion. Single tooth dento-osseous osteotomy is considered to be a surgical technique with minimal effect on the pulp and periodontium. We used this method to treat a patient with impacted permanent canine teeth. After concomitant single tooth dento-osseous osteotomy and orthodontic treatment, root resorption of the bilateral canines was kept to a minimum and pulp vitality was confirmed. This method may be effective in patients in whom ordinary traction is difficult.

Gigantic peripheral osteoma of the mandible

Osteomas are osteogenic lesions which have a limited growth potential. They are comprised of histologically and radiographically normal bone. Osteomas are classified as central, peripheral or extraskeletal according to the location. Clinically, peripheral osteomas (PO) are unilateral, sessile or pedunculated and have mushroom-like lesions ranging from 10–40 mm in diameter. Osteomas affecting the mandible are rare but are seen in young adults and usually remain less than 2 cm in size after years of slow growth. In this report a gigantic peripheral mass on the right mandible of a 25-year-old patient exhibiting clinical signs related to neoplasia is presented. The patient also suffered from an impacted canine tooth. The oral and maxillofacial surgeon and the dentist need to be aware of the components of this entity because manifestations in the head and neck including epidermoid cysts, osteoma, odontoma, exostosis, supernumerary and impacted teeth are common.

3D CT based rating of unilateral impacted canines

ObjectiveThe aim of this study was to develop a reference system for multislice computed tomography (MSCT) images to determine of the location of impacted teeth in metric terms. Study designThe CT data of 17 patients with unilateral impacted maxillary canines were selected retrospectively from existing MSCT data sets. In a reference coordinate system, defined by anterior nasal spine (ANS), posterior nasal spine (PNS), and A-point, the axis length and the inclination of the canines were determined and impacted and non-impacted canines were compared. ResultsThere were significant differences between the impacted and non-impacted canines (p≤0.0003) for all inclinations and the lengths in the x- and z-axes. The measurement of the inclination and sections of the impacted and non-impacted canine tooth axes showed sufficient repeatability and reproducibility. ConclusionThe coordinate system proved to be suitable for the exact metric localization of impacted teeth.
