Structure and form particularities of interradicular and interdental septa
Nicolae Testemitanu State University of Medicine and Pharmacy, Chisinau, Republic of Moldova, The 6th International Medical Congress for Students and Young Doctors, May 12-14, 2016Introduction: Interdental and interradicular septa represents anatomical structures that reference
in different types of pathologies like: marginal periodontitis, paradontosis and dental migrations. In
literature does not exist enough information about the structure and form varieties of interalveolar
septa. We can mention next forms of septa: sharp lance form, dome form, crescent form and dissected form
which is divided in: dissected properly and dissected in steps. All this types of forms have a different
influence on pathological appearance on the bone structure. Another particularity is an cortical difference
that may be not so pronounced at some persons, while to others it is more pronounced. Also a particularity
is in the structure of cancellous bone where we can see the distance between bone trabeculae. By time
in some pathological conditions we atest changes in interrdental and interradicular septa - thinning the
cortical at septa's peaks, outbreaks of spongy bone tissue thinning etc.
Purpose: Studying varieties of form and factors that influence their changes at interdental and
interradicular septa's level in normal and pathological cases.
Material and methods: Were studied 132 radiograms of patients that received medical help in
USMF ,,Nicolae Testemitanu" dental clinic and in private dental clinic ,,Parodent Prim" SRL from
Chisinau city. Radiographic clichés were analized at fluoroscopy. For study we used Новик И.О.
classification.The method of collectioning the information was by selective method-were selected only
radiograms that coresponded our classification criteria. Therewith we used the method of observation
and analyze of types of interdental and interradicular septa in norm and pathological disease.
Discussion results: Anatomical structures of interdental and interradicular septa are in strong
relation with various factors: tooth anatomy of teeth and their position in the dental arch, type of
vascularization, local physico-chemical conditions and local systemic factors. The interdental septum
protrude at alveolar level and is more massive in relation with vestibular and oral alveolar wall.
Interradicular septum are perfored by multiple holes, through which nervs and blood vessels pass.
Cortical thickness is reduced at maxillary level than at mandibula. Normally the anatomical structure of
septum is not standart, it has individual particularities (of shape, bone density).
Analyzing the obtained data, we found that from 132 radiograms only 19 (14.39%) of cases was
detected with normal structure interdental and interradiculare septa to young persons - 16-35 years. From
this numbers, dome shaped septum -27,2 %; sharped lance- 25,3 %; halfmoon-46,72% and dissected
shape-0,78%.
Conclusion: 1. The analysis of data from speciality literature that confirms the four types of
interdental septum: dome shaped, halfmoon, sharped lance and dissected shape. 2. The basic factors that
influence the shape of septa are: the teeth anatomy and their position in arch, the functional ocluzal
forces that are transmitted, type of vascularization, physico-chemical conditions of individual local and
systemic factors. 3.Obtained results are in relationship with results from speciality literatury that refers to
the form of septum: dome-27,2%; sharped lance- 25,3%; halfmoon-46,72% and dissected form-
0,78%. 4. Pathological condition mostly apears molars region where prevail the dome shaped septa
A.: Using Textual and Visual Processing in Scalable Concept Image Annotation Challenge
Abstract. This paper describes UAIC 1 's system built for participating in the Scalable Concept Image Annotation challenge 2015. We submitted runs both for Subtask 1 (Image Concept detection and localisation) and for Subtask 2 (Generation of Textual Descriptions of Images). For the first subtask we created an ontology with relations between concepts and their synonyms, hyponyms and hypernyms and also with relations between concepts and related words. For the second subtask, we created a resource that contains triplets (concept1, verb, concept2), where concepts are from the list of concepts provided by the organizers and verb is a relation between concepts. With this resource we build sentences in which concept1 is subject, verb is predicate and concept2 is complement
