Methodological instruction for students of the 5 year
faculty of dentistry
(Orthodontics)
Lesson №6 (practical – 6 hours)
Professional orientation of students: There are antenatal and postnatal causes of abnormalities and deformities bite. When deformations dentition in children occur malocclusions are violated all the features of maxillofacial area. By dentition defects resulting premature loss of a tooth, endocrine pathology. Pediatric infectious diseases, the negative impact of environment change the shape and function of the teeth and jaws apparatus.
Theme 1. Features prevention maxillodental-facial anomalies in the antenatal period. The most common injury maxillodental-facial, which can cause abnormal births, their prevention.
Aim: To study the features of prevention anomalies in the antenatal period, the most common injury maxillodental-facial, which can cause abnormal births, their prevention.
Objective: To determine the types of skull deformations that occur during pathological delivery (inadequate size of fetal head size of the pelvis of the mother).
Questions to the theme 1:
1. Antenatal causes of abnormalities and deformities bite.
2. Postnatal causes of abnormalities and deformities bite.

Practical work (9.00-12.00 hours)
Work 1.Orthodontic examination of the child or student
Venue: hall clinical department of pediatric dentistry.
Object: patients with defective teeth or diagnostic phantom model.
Tools for group: dental unit-1, chair for patient – 1, a chair for the doctor-1, table doctor-1 tool set, 10-13.
Tools for student: dental unit-1, chair for patient – 1, a chair for the doctor-1, table doctor-1 tool set (tray, tube, mirror, tweezers).
The task for the student: a study of children who come to the clinic to conduct certain scheme. Typically, first collect detailed medical history. Through the survey, ascertain the causes of defects in teeth and dentition. In each case it is necessary to find a functional failure dental system due to the presence of dentition defect, such as dysfunction of speech, chewing, the impact of the defect on the psyche of the child. After embarking on the survey objective test that begins with a general review. At the same time pay attention to a child’s development (physical and mental), then transferred to an external review of facial area, mouth.
Time spent on the work 60 minutes.
Method of execution:
Studying a person must pay attention to the parts of the face of proportionality and severity of nasolabial, as well as the provisions of the lips. Next, examine your mouth and it porch. Review lining the lips, cheeks, transitional folds and alveolar processes, palate, floor of the mouth and tongue done to identify and study this condition. For definition of around dental tissue in children is most often used sample Schiller-Pisarev pursued after oral hygienic treatment. In the study of transitional folds of mucous oral attention should be paid location bridles upper and lower lip, which is sometimes the cause of diastema between the central incisors. Then go to the view of dentition in the upper and lower jaws, teeth and investigating of their condition. We must pay attention to the stability of the teeth and the shape of the alveolar process, palate (high, normal, flat, gothic, dome), the size of the tongue. Then examine the shape, the size of both dental arches, the position of each tooth in the dental arch, presence or absence of diastema and only then determine the correlation between tooth rows, bite. It is necessary to study the relationship of each tooth with its antagonists, pay special attention to the articulation of molars and the degree of overlap of the upper frontal teeth bottom. We provide description of the dentition in 3 planes: sagittal, transversal, vertical.
Tasks for self-study: determination of facial and jaw signs on examination.

Aim: To study the preventive measures maxillodental-facial anomalies and deformations in the postnatal period, the role of childhood infectious diseases in causing maxillodental-facial anomalies and deformations of the negative impact of the ecological environment, the impact of the endocrine system on development maxillodental-facial apparatus.
Objective: to be able to assign auxiliary examination methods in different clinical forms maxillodental-facial abnormalities and deformities.
Questions to the theme 2:

Work 2.Measuring the apical base.
Venue: hall clinical department of pediatric dentistry.
Object: plaster model
Tools for group: 13 Calipers
Tools for student: calipers
The task for the student :measure apical bases, analyze ratio of apical Basis and amount mesiodistal size 12 permanent teeth of each jaw.
Time spent on the work 60 minutes.
Method of execution: Dimensions apical base measured in transversal (width) and sagittal (length) direction, by Hausa in the modification N.G. Snahinoyi. Apical base width of the upper jaw is determined on a plaster model in a straight line between the deepest point in the area foosa canina (in deepening between the tops of the canines and first premolars), and the model of the mandible measurements made between these same teeth, receding from the level of gingival margin 8mm. Length of apical base is measured on the upper jaw from point A (the intersection of the median palatine suture with the line connecting the central incisors in the neck area of the palatal surfaces) the median palatine suture to the line connecting the distal surface of the first permanent molars. The lower jaw – from point B (the front surface of the cutting edges of the central incisors) along the perpendicular to the intersection with the line connecting the distal surface of the first permanent molars.
Normally apical base width of the upper jaw is-44% lower and 40% of the mesiodistal size 12 permanent teeth of each jaw. With the same width associated dentition in the area of premolars (39.2%) and molars (50.4%). So for example if the amount mesiodistal size 12 permanent teeth 100mm, the apical base of the upper jaw is 44mm, bottom- 40mm, and the width of the dentition in the area is 39.2 mm premolars and molars in the region – 50.4 mm.
Tasks for self-study:
– Ton-defined indexes, Pona

Work 3: assess the condition around dental tissues in children
Venue: hall clinical department of pediatric dentistry.
Object: patients or diagnostic phantom model.
Tools for group: dental unit-1, chair for patient 1, a chair for the doctor-1, table doctor-1 tool set, 10-13.
Tools for student: dental unit-1, chair for patient 1, a chair for the doctor-1, table doctor-1 tool set (tray, tube, mirror, tweezers).
Time spent on the work 60 minutes.
Method of execution: for the quantitative assessment of tissue in children around the age of 12 years using a comprehensive periodontal index (CPI), the proposed P.A. Leus (1988), after 12 years of use index CPI. Definition CPI conducted using the usual set of dental tools. In children 3-4 years examined periodontal tissue of teeth 55, 51, 65, 75, 71, 85, children 7-11 years – teeth 16, 11, 26, 36, 31, 46, in adolescents and adults – tissue surrounding teeth 17/16, 11, 26/27, 36/37, 31, 46/47.
Code CPI:
0 – healthy periodontium – signs of periodontal tissue destruction with the instrumental study is not defined;
1 – plaque – any minimum number of plaque detectable in probing the interdental spaces surface of crowns;
2 – bleeding – defined at the light sensing dental gingival groove;
3 – tartar – roughness on the surface of the tooth or by gingival region;
4 – pocket – gum, determined by the probe;
5 – Tooth mobility – abnormal mobility of II-III degree.
Tasks for self-study:
– Determine the suitability of the tooth under resistance in orthodontics;
– Determine the suitability of the tooth under resistance in prosthetic child at different ages
