Dental Transposition of Mandibular Canine and First Premolar – the first Case Report

Case Reports in Odontology, 2014

Dental transposition is a form of ectopic eruption with change in position of normal adjacent teeth. Its prevalence is very low in general population and could be frequently missed on oral examination. We present a rare case of dental transposition between left mandibular canine and first premolar in a 22 year old Libyan male patient. ...Read more

Case Reports in Odontology. 1(1), 02-04 Retrieved from http://www.casereportsinodontology.org Page | 3 Introduction Tooth transposition is defined as ‘the positional interchange of two adjacent teeth – particularly of the roots – or the development or eruption of a tooth in a position occupied normally by a non-adjacent tooth ‘– Peck et al [1] . Tooth transposition is an anomaly of eruption characterized by interchanged position of two adjacent teeth [2] . Mandibular transposition is rare and it is frequently reported only with mandibular canine and lateral incisor [2] . To the best of our knowledge, we report the first case report of dental transposition of mandibular canine and first premolar of a Libyan patient in English literature. Case Report A 22-year-old male patient of Libyan origin, reported to the outpatient department of Faculty of Dentistry, Sebha University, Sebha, Libya. He complained of pain in a decayed tooth in lower left front region. He also complained of food impaction between teeth and difficulty in mastication. His medical history and personal history was non-contributory. Past dental history revealed that he had undergone uneventful extraction. The intraoral examination revealed transposition of left mandibular canine and first premolar. The mandibular canine was rotated medially and there was spacing between the first premolar and lateral incisor (Figure 1). Intra-oral periapical radiograph revealed dental transposition along with carious lesions in 33 and 34 besides remaining root of 35 (Figure 2). The patient was advised restoration of carious teeth, extraction of the root stumps and orthodontic correction. Discussion Dental transposition is identified as complete transposition when the crowns and the roots of the involved teeth exchange places in the dental arch and incomplete transposition when the crowns are transposed, but the roots remain in their normal positions. The canine is one of the most commonly involved teeth in the transposition phenomenon [3]. Etiology of transposition is not known. Proposed causes include abnormal displacement of tooth bud or deviation during tooth development, genetic interchange between tooth buds, mechanical interferences in eruption, early loss or prolonged retention of deciduous teeth [2]. In general population, the prevalence of dental transposition is around 0.4%. It frequently involves mandibular canine/lateral incisor and on the left side [3, 4] . Herewith, we give the first report of mandibular canine transposition and first premolar in a male Libyan patient for the first time in English literature. Conclusion The true cause of such anomalous eruption could be elucidated only with genomic investigations. We recommend an accurate oral examination for identifying such rare anomalies, initiate prompt treatment for restoration of esthetics and occlusion.

B.为什么我们提供的毕业证成绩单具有使用价值？查询留服认证是国内鉴别留学生海外学历的唯一途径但认证只是个体行为不是所有留学生都操作所以没有办理认证的留学生的学历在国内也是查询不到的他们也仅仅只有一张文凭。所以这时候我们提供的和学校颁发的一模一样的毕业证成绩单就有了使用价值。

The purpose of this paper is to investigate the application of the Husserlian concept of “motivation” to the affective domain and specifically to moods (Stimmungen) (Lee 1998; Quepons Ramírez 2015; Zirión Quijano 2018), in light of the recently published second volume of the Studien zur Struktur des Bewusstseins (Husserl 2020). In doing so, I aim at understanding affects as episodes that exhibit concrete temporal connections between experiences, which significantly enriches the formal structures depicted in the famous lectures on time (Husserl 1928). The paper revolves around a paradox about moods. Suppose I am attending a magnificent religious ceremony. During this event, I am intentionally directed towards its sacred value, which motivates a solemn feeling. However, such a feeling does not cease with the ceremony, but survives even when the value is no longer explicitly aimed at (Husserl 2004a, 176). In this perspective, moods can be regarded as feelings that persist after their axiological source of motivation has disappeared (Husserl 2020, 182). This claim, however, raises a major issue: how can these feelings endure (sometimes for days or months) after they have been ‘uncoupled’ from their intentional relation (Fisette 2021, 227)? The paper is divided into three parts. Part I explores the relationship between valueceptions (Wertnehmungen) and emotions (Gefühle). In the Studien manuscripts, Husserl, contrary to what has long been assumed (Tappolet 2000, 7; Mulligan 2010, 483; Müller 2019, 54; Yaegashi 2019, 73; Müller 2020, 116), does not regard the two as identical, but sees emotions as reactions motivated by appearing values (Husserl 2020, 55, 118; Delamare 2022). This ‘reactional’ interpretation appeals to an essential feature of the concept of ‘motivation’ (Perreau 2013, 60), namely, that the emotion is not a mechanical effect of the valueception (Husserl 2020, 171), but a meaningful response: I rejoice about a painting in light of (um … willen) its beauty (Müller 2021a, 4). These clarifications are then applied to the nature of mood, which Husserl defines as the continuation of the emotion over the course of the affective episode. Two explanations for such a continuation are examined. Part II (negatively) shows that the temporal structures of retention, memory, and sedimentation, are not sufficient to elucidate the status of moods as occurrent (as opposed to past) feelings. Part III provides the (positive) solution to this puzzle, drawing on the embodied dimension of emotions in the form of sensuous feelings (Gefühlsempfindungen). Aesthetic joy, for instance, is not a purely mental event, but involves a bodily resonance (Fuchs 2022), e.g., a shiver of pleasure. Such feelings, in turn, endure (Husserl 2020, 123), due to the inertia of the body, once the valueception is no longer enacted (Husserl 2020, 522–523), leading to the emergence of a new, diffuse form of intentionality, as a “coloring” of the whole situation (Husserl 2004a, 176; Husserl 2020, 172, 181). As a result, it is the definition of moods as “annexes of sensuous feelings” (Husserl 2020, 173), and thus as embodied affects, that accounts for their lastingness.
