AbstractIntroduction: Tooth impaction is defined as the absence of a tooth on the arch, after its normal eruption age. The main reason canines are impacted is the lack of space required for the tooth to erupt.Aim of study: The main objective of this study is to determine the types of malocclusions associated with canine impaction (Lindauer classification). A secondary objective is to establish the correlation between these parameters and identification of subjects with high risk of canine impaction based on pre-existing malocclusion.Material and methods: This study was performed on a sample of 20 patients, 9 men and 11 women. The dental casts were subject to Angle classification and various measurements such as arch perimeter, Pont’s index, sum of the mesiodistal width of the incisor and arch length were performed. The Lindauer sectorial classification was determined based on the patients’ panoramic radiography.Results: According to the data collected, the Class II /2 malocclusion is more frequent, and it is associated with the impacted canine (approximately 50%). According to the Lindauer classification higher frequency of the impacted canines was found in Sector IV.Conclusion: The diagnosis for impacted canines is often associated with Class II /2 malocclusion, and according to the Sector classification, it is often localised in Sector IV.

Latar belakang: suatu kasus impaksi gigi dapat menyebabkan maloklusi, dan kelainan oklusi akan semakin bertambah dengan bertambahnya usia. Impaksi gigi kaninus merupakan gigi kedua setelah gigi molar ketiga yang berfrekuensi tinggi untuk mengalami impaksi, persentasenya sekitar 12%-15% dari populasi. Gigi supernumerary adalah gigi tambahan/berlebih, sehingga jumlah gigi yang terbentuk dalam rahang lebih banyak dari jumlah normal. Terjadinya impaksi gigi kaninus dan supernumerary secara bersamaan jarang terjadi. Tujuan: Menambah wawasan du bidang bedah mulut minor, terutama dalam menangani suatu kasus impaksi gigi kaninus dan supernumerary untuk perawatan orthodonti. Kasus dan Penanganan: Dilaporkan seorang apsien, wanita, berusia 38 tahun yang baru menyadari kelainan maloklusinya dengan keluhan gigi depannya bertambah maju akibat adanya impaksi gigi kaninus dan impaksi gigi supernumerary. Pasien dikonsulkan dari Bagian Orthodonti ke Bagian Bedah Mulut untuk penanganan impaksi gigi kaninus dan supernumerary dengan kemungkinan untuk mempertahankan gigi kaninus memulai pembedahan. Dengan berbagai pertimbangan, penderita pada akhirnya menjalani operasi pengambilan gigi kaninus dan gigi supernumerary di Bagian Bedah Mulut RSGM Prof. Soedomo. Langkah-langkah diagnosis, operasi dan berbagai kemungkinan komplikasi juga turut disertakan di dalam pembahasan. Kesimpulan: Pengambilan gigi kaninus dan gigi supernumerary yang terpendam merupakan pilihan perawatan jika tidak memungkinkan untuk dilakukan exposure pada impaksi gigi kaninus pada maksila. Background: Impacted canines is the second most impacted tooth after third molar impaction, approximately 12%-15% of the population present with impacted canines. A supernumerary tooth is one that is additional to the normal series and can be found in almost any region of the dental arch. The incidence of an impacted canines as a sequent with a supernumerary tooth is very rare. Purpose: The aim of this case report is to add more information about a minor surgery due to canine and supernumerary tooth impaction for orthodontic treatment. Case and Management: We reported a case of a woman, 38 years old who have noticed a malocclution through the forwardness movement of her anterior teeth, due to the present of impacted canine and supernumerary. The patient consulted from orthodontic department to oral and maxillofacial department for further assessment, treatment and also the probability for surgical exposure of impacted canine. We have decided to do odontectomy for the impacted canine and supernumerary tooth as well at Oral and Maxillofacial department, Prof. Soedomo Hospital. The diagnosis process, exposure of impacted canine considerations are also discussed. Conclusion: the odontectomy for impacted canine and supernumerary teeth had performed as last options if there is impossible to do an exposure of an impacted canine.

Impacted Canine

Tooth impaction is the retardation in the eruption pattern of a tooth. One of the most commonly impacted teeth is the maxillary canine. However, impaction of mandibular canines is not as common as maxillary canines. Treatment of such impacted teeth usually involves surgical exposure, followed by bonding of an orthodontic attachment to facilitate extrusive movement of the impacted tooth. However, some side-effects on other teeth can be expected which includes the intrusion and tipping of adjacent teeth. In order to prevent side-effects on the adjacent teeth, we present a modified uprighting spring used to extrude an impacted canine.

Impacted Canine

The importance of maxillary canine impaction is that it may compromise dental health , particularly because a small but significant proportion of impacted canine is associated with the resorption of the roots of neighbouring teeth. A few cases of impacted upper canines, premolar and central incisors of different ages are presented. Although the best treatment alternative for impacted teeth is extraction, the same cannot be directly applied to canines and central incsor especially. Since canines present with them a high demand on aesthetic and functional requirements. Thus, alignment of impacted canines into the arch is the best treatment approach. The purpose of this study is to evaluate the impacted maxillary canines that were surgically exposed, followed by orthodontic alignment into occlusion.

Objective The present study evaluated the reliability of digital panoramic radiography in the diagnosis of carotid artery calcifications. Materials and Methods Thirty-five patients under high-risk for development of carotid artery calcifications who had digital panoramic radiography were referred to undergo ultrasonography. Thus, 70 arteries were assessed by both methods. The main parameters utilized to evaluate the panoramic radiography reliability in the diagnosis of carotid artery calcifications were accuracy, sensitivity, specificity and positive predictive value of this method as compared with ultrasonography. Additionally, the McNemar's test was utilized to verify whether there was a statistically significant difference between digital panoramic radiography and ultrasonography. Results Ultrasonography demonstrated carotid artery calcifications in 17 (48.57%) patients. Such individuals presented with a total of 29 (41.43%) carotid arteries affected by calcification. Radiography was accurate in 71.43% (n = 50) of cases evaluated. The degree of sensitivity of this method was 37.93%, specificity of 95.12% and positive predictive value of 84.61%. A statistically significant difference (p < 0.001) was observed between the methods evaluated in their capacity to diagnose carotid artery calcifications. Conclusion Digital panoramic radiography should not be indicated as a method of choice in the investigation of carotid artery calcifications.

ABSTRACT Orthodontic traction of impacted canines stands as a major challenge for Orthodontics. It is a relatively frequent clinical complaint which management, more often than not, requires a multidisciplinary approach. Surgical exposure of the impacted canine, and the complex orthodontic mechanics applied to align the tooth back into the arch, may frequently lead to complications involving supporting tissues, not to mention the long treatment time and high costs imposed to patients. In face of that, it is worth highlighting the relevance of early diagnosis as to intervene efficiently and as soon as possible. This paper presents a review of the main concepts involving prevalence, etiology and classification of impacted canines, and describes the different clinical management options that would help solve the problem. It illustrates the topic by presenting a treatment delivered to a 13 year 7 months old male patient, suffering from a Class II, division 2, left subdivision, malocclusion, associated to a deep bite and a prolonged retention of a primary upper canine caused by the impaction of the permanent tooth. Corrective orthodontic therapy was associated to a rapid maxillary expansion and to the use of a high pull headgear. Impacted canine was submitted to orthodontic traction and correctly positioned back into the arch. This approach proved to be efficient in meeting both functional and aesthetic goals.

: Tooth impaction is defined as a partial or complete eruption of a tooth regarding the eruption time. Hereby, we present an infectious canine in a 38-year-old man that primarily presented with chest pain and dyspnea. After two days, he demonstrated a painful swelling and erythema of the face, severe perspiration, nasal congestion, and pleural effusion. The patient was diagnosed with acute bronchitis, mucormycosis, and nasal septum abscess, leading to unnecessary antibiotic therapy and lack of treatment response. After oral and maxillofacial surgery consultation, cone-beam computed tomography (CBCT) revealed an impacted and infectious canine that was surgically extracted. Due to lack of desired response to treatment, he underwent CBCT after oral and maxillofacial surgery consultation. An impacted and infectious canine was detected, which was surgically extracted. Three days later, his symptoms significantly improved, and he was discharged with a stable general condition.

Risk Levels

The risk of slope failure is determined by the degree of damage caused by the slope slide. For the special-high slope of some high-risk water conservancy and hydropower projects, the standard should be appropriately raised. Thus, the safety standard for these slopes is explored on the basis of reliability analysis. The slopes with high risk of failure are divided into special class I and special class II slopes depending on the risk levels and acceptable risk standards. The concept of reliability theory-based relative ratio of the safety margin is utilized to establish the relationship between annual failure probability and safety factor, thereby obtaining the reasonable safety factors for different slopes. Results show that the values of safety factors for special class I and special class II are 1.40 and 1.35, respectively. These results can provide a reference for exploring the safety standards of dams with a height of more than 200 m.

Delayed Eruption

Impacted teeth are those with a delayed eruption time or that are not expected to erupt completely based on clinical and radiographic assessment. Palatal displacement of the maxillary canines is defined as the developmental dislocation to a palatal site often resulting in tooth impaction requiring surgical and orthodontic treatments. Impacted permanent maxillary canine occur in 1-2% of the population. The Occurrence of impacted permanent maxillary canines are; 85% palatal and 15% labial. The prevalence of palatally displaced canines (PDC) fluctuates between 0.8-5.2%. Palatally erupting or impacted maxillary canines occur twice often in females than males, and are five times more common in Caucasians than Asians. Of all patients with maxillary impacted canines, 8% have bilateral impactions.DOI: http://dx.doi.org/10.3126/ojn.v3i1.9285 Orthodontic Journal of Nepal, Vol.3, No.1, 2013: 63-68
