Transmigration of impacted canines: A report of four cases and a review of the literature.
Idris Faiq Qaradaghi
Hellenic Orthodontic Review , 2009,
Abstract: INTRODUCTION: Impacted canines are not uncommon in clinical practice, but intraosseous movement of impacted canines crossing the midline (transmigration) is considered as a rare phenomenon, especially with regard to the mandibular canine. The etiology of transmigration is not clear and early radiographic examination of the patient is of significant importance. AIM: The purpose of this article is to report 4 cases of impacted canine transmigration and review the literature in order to highlight the importance of early detection by panoramic radiographic examination, which may avoid future complications. METHODS: Pretreatment computerized panoramic radiographs.RESULTS: Panoramic radiographic examination of four patients revealed that three patients presented with one impacted transmigrated canine, while the fourth patient with bilateral transmigrated canines. Of the first three transmigrated impacted teeth, the mandibular canine was involved in two instances and the maxillary canine in one instance. Of the three unilateral impacted transmigrated teeth, the left canines were involved. In two cases the transmigrated canine was associated with congenital missing of teeth.CONCLUSION: Migration of the canine through the midline is infrequent and normally asymptomatic. The diagnosis of transmigrated canines is based on the absence of the corresponding permanent canine in the arch as well as on the radiographic findings in both intraoral and panoramic radiographs. Early examination aids in proper treatment planning.

Abstract: Introduction: Dental evidence is valuable in identification of individuals, especially following mass disasters; estimation of ageat death of skeletonised remains and establishing guilt in cases of criminal injury by biting. Mandibular canines are found to exhibit the greatest sexual dimorphism amongst all teeth. Objective: To investigate the accuracy with which gender can be differentiated by using the mandibular canine index in the Punjabi – Pakistani population. Setting: Independent Medical College and Punjab Medical College, Faisalabad. Period: Dec. 2008 to Dec. 2009. Material and Methods: The present study was performed on 200 students, between the age group of 18-25 years, randomly sampled with informed consent (Through 3rd party). Mandibular canine width and intercanine distance were measured with the help of Vernier caliper after observing aseptic conditions. Mandibular canine index was calculated and the observed MCI was compared with the standard MCI value. The data was then analyzed using student’s “t” test. Results: No significant statistical difference was noted between the right and left mandibular canines amongst males and females (same sex) but when comparing between males and females, there was highly statistical significant difference (P < 0.001). The calculated standard MCI for canines of males and females found to be 0.2504. With these calculations we could predict sex correctly at 75.97% in this study (Male: 71.67% and Female: 78.72%). Conclusion: MCI is a quick and reliable method for sexual identification when a standard for the population is available. With these calculations, we could predict the sex correctly at75.97 % in this study. This method can be used as adjunct to other available tools for sex determination. DNA studies can reveal sex accurately. Availability of comprehensive database with “NADRA” can also be used as adjunct to “MCI” to enhance the accuracy in determination of sex and identity of the person in Pakistan.

Abstract: disturbances involving abnormalities in tooth eruption are named ectopia. transmigration is the name assigned to ectopia in the presence of teeth in areas distant from the alveolar process. initial angulation of the tooth bud of the second premolar and premature loss of permanent mandibular 1st molars can influence the distal migration of the second premolar. some studies have observed that ectopic teeth can be found in a variety of places around the oral cavity and also in other areas of the human body. there are records of teeth in the maxillary sinus, mandibular condyle, coronoid process, mandibular angle, orbit, palate, mentum and also the skin. the prevalence of tooth abnormalities is higher in children with cleft lip and palate compared to children without clefts. this paper presents a case report of migration of the mandibular left second premolar in a patient attending the hospital for rehabilitation of craniofacial anomalies of the university of s?o paulo (hrac/usp), brazil. migration of the mandibular left 2nd premolar was confirmed by 8 panoramic and 1 periapical radiographs obtained during patient's treatment between 1978 and 2002, which were available in the files of the department of dental radiology of hrac/usp. it can be assumed that distal migration of the mandibular left 2nd premolar is not associated with presence of cleft lip and palate; observation of these two events in a same patient is rare, since no similar reported cases were found in the literature.

Abstract: Angiostrongylus cantonensis is a metastrongyloid nematode that normally lives in the right ventricle and pulmonary arteries of rats, its definitive (permissive) host [1]. While many species of rats can carry patent infections, the Norwegian rat (Rattus norvegicus) and the black rat (Rattus rattus) are considered the most important definitive hosts. In wild populations of rats, A. cantonensis infections cause little disease, as expected for an efficient parasite [1-3]. Dogs, humans, horses, Australian native mammals (e.g. possums, macropods, macrobats) and birds (e.g. tawny frogmouths), and various zoo animals are non-permissive "accidental" hosts that become infected after ingesting third-stage larvae (L3) in intermediate hosts (molluscs) [1,4] or transport hosts (such as planarians, frogs, fish and crustaceans) [5-7]. Tawny frogmouths and Australian marsupials are highly susceptible to clinical neural angiostrongylosis.In rats, following digestion, L3 migrate from the gut to peripheral nerves, nerve roots, spinal cord and brain [8]. A. cantonensis shows obligate neurotropism, i.e. larvae must migrate through the central nervous system (CNS) before taking up residence in the pulmonary arteries, where they subsequently mate and produce eggs which embolise in the pulmonary capillary bed. Larvae migrate up the trachea, then are coughed up, swallowed and passed in the stool, where they access intermediate mollusc hosts (slugs or snails). Virtually all species of native and introduced terrestrial molluscs in Australia are suitable intermediate hosts [1].Larval neurotropism dominates disease pathogenesis in non-permissive hosts like dogs and people. In human patients, signs of NA include headache, fever, nausea, vomiting, neck stiffness, paraesthesia, face or limb paralysis, photophobia, diplopia, coma, seizures and even death [9-11]. Canine NA usually results from ingestion of slugs, snails or paratenic hosts containing infective L3 [12-15]. After ingestion, larvae leave

Abstract: A case of pigmented calcifying cystic odontogenic tumor associated with odontoma occurring at the mandibular canine-premolar region of a young Japanese boy is presented with radiographic, and histological findings. Special staining, electron microscopic study and immunohistochemical staining were also done to characterize the pigmentation.The pigments in the lesion were confirmed to be melanin by Masson-Fontana staining and by transmission electron microscopy. The presence of dendritic melanocytes within the lesion was also demonstrated by S-100 immunostaining.The present case report of pigmented calcifying cystic odontogenic tumor associated with odontoma features a comprehensive study on melanin and melanocytes, including histochemical, immunohistochemical and transmission electron microscopic findings.Pigmented odontogenic lesions are rare, with only 47 cases reported in English literature since 1961 [Table 1]. Most of these pigmented lesions were found in racially pigmented patients. This is a case report of a pigmented calcifying cystic odontogenic tumor (CCOT) with special, ultrastructural and immunohistochemical findings together with a brief review of the English literature on pigmented odontogenic lesions especially pigmented CCOT.A 15-year-old Japanese boy was referred to the Okayama University Hospital by the orthodontist for management of a mixed radiolucent and radiopaque lesion in the left mandibular canine-premolar region detected during routine radiographic examination. The lesion was asymptomatic and the patient's medical and family histories were non-contributory.On intraoral examination, there was no bony expansion and the overlying mucosa was also normal. Panoramic radiograph showed a well-defined unilocular radiolucent lesion with distinct sclerotic margin containing radiopaque masses [Fig. 1] and CT scan revealed that the lesion was lingual to the left mandibular canine. The lesion was small and the radiodensities of the included masses were co

Abstract: Objective: To compare the effectiveness of topical fluoride application and fluoride The purpose of this paper is to bring about a better appreciation of causative factors and those influencing management decisions of the unerupted maxillary canine. It reviews current literature of the anomaly of the unerupted maxillary canine, which is one of the most frequently displaced teeth in the maxillary arch. Aetiological factors of this anomaly are widely varied and include advanced state of development at an early age, trauma, dentoalveolar disproportion, absence or reduction in size of the upper lateral incisor and genetics. The possible complications of canine impaction are also discussed. Methods of assessing the unerupted canine both clinically and radiographically are highlighted along with ways of predicting and preventing the anomaly. Finally it details management of the problem including factors to be taken into consideration prior to treatment and the various treatment options available to date. The need for early assessment of patients presenting in the dental clinic cannot be over-emphasized in the possible prevention of this anomaly. The observation of one or more of the possible causative factors as well as delayed eruption of the permanent canine or prolonged retention of its predecessor should also be cause for further investigation. Choice of the various treatment options available is dependent on a number of factors including patient`s attitude, the position of the unerupted tooth relative to the standing teeth as well as the present occlusion of the patient.

Abstract: One of the major roles of forensics in human identification is establishment of sex of the individual. In this study, a thorough anthropometric evaluation of mandibular canine width and intercanine distance was carried out on 300 apparently healthy individuals whose ages ranged between 18-30 years at a gender ratio of 1:1 so as to determine the sex of an individual and to investigate the possibility of dimorphism of the canines being used as a valid tool in the forensic and legal identification of an individual. These measurements were done with the aid of a digital vernier caliper while the mandibular indexes were derived by the division of the mandibular canine width by the intercanine distance. The values were subjected to analysis and there was great evidence of sexual dimorphism. The males have significantly greater mandibular canine width when compared to females. In males, the mean Right mandibular canine width was 7.79±0.05 and the mean Left mandibular canine width was 7.88±0.05, while in females was 6.76±0.05 and 6.75±0.05, respectively. The percentage analysis of sexual dimorphism showed that the left mandibular canine exhibited a greater degree of sexual dimorphism. The intercanine distance showed a high degree of sexual dimorphism which was found statistically significant. The mandibular intercanine distance was 34.20±0.19 in males and 32.64±0.22 in females.
