Summary:

The purpose of research is to reveal the anatomical variability of the shape and size of the greater palatine canal and the greater palatine foramen in men of the first period of adulthood. Material and Methods. The object of the study included 129 men of the first period of adulthood (from 20 to 35 years). The number of the greater palatine foramen, their shape, antero-posterior and medio-distal diameters, the length of the greater palatine canal, its shape, its medio-distal and antero-posterior diameters in the upper, middle and lower thirds of the canal were determined on cone-ray computed tomograms. Results. In men of the first period of adulthood, the medio-distal diameter of the greater palatine foramen on the right averaged 3.67±0.79 mm; on the left, 3.64±0.80 mm; the antero-posterior diameter of the greater palatine foramen on the right averaged 5.79 ±0.86 mm; on the left, 5.73±0.84 mm. 10 forms of the greater palatine foramen were identified: oval, elongated in the antero-posterior direction, helical, crescent-shaped, triangular, teardrop-shaped, round, bean-shaped, diamond-shaped, semicircular and ovoid. The length of the greater palatine canal on the right is 33.59±2.87 mm, on the left — 32.94±2.92 mm. 6 forms of the greater palatine canal were identified: wave-shaped, funnel-shaped with a bend in the lower third, hourglass shape, zigzag, crescent, straight shape. Conclusion. The greater palatine canal and the greater palatal foramen have a pronounced variability in size, shape and topography in men of the first period of adulthood. However, no significant bilateral differences in the medio-distal and anteropos-terior diameters of the greater palatine foramen and the length of the greater palatine canal were found.

Dimensional characteristics of periodontal fissure in adults with increased tooth abrasion according to dental computed tomography

Year: 2020, volume 16 Issue: №1 Pages: 108-114
Heading: Human anatomy Article type: Original article
Authors: Kalmin O.V., Koretskaya Е.А., Zyulkina L.A.
Organization: Penza State University
Summary:

Aim is to analyze the dimensional characteristics of the width of the periodontal fissure in the teeth of the upper and lower jaws with increased tooth abrasion in adults. Material and Methods. 204 people of both sexes aged 22 to 60 years were served as the object of the study. Using cone beam computed tomography, the width of the periodontal fissure was studied at the level of transition of the upper third to the middle third of the root, at the level of transition of the middle third of the root to the lower third, and at the level of the apex of the tooth root. In the upper molars, the measurements were performed at the palatine root, in the molars of the lower jaw — at the distal root. Results. The dimensional characteristics of the width of the periodontal fissure on both jaws statistically significantly increase from the first period of adulthood to the second in persons of both sexes: in men at the level of the upper third of the root by 12.5-96.3%, the middle third —11.8-78.6%, tops of the tooth root —22.2-106.7; in women —by 2.4-65.8, 3.0-22.0and 19.1-93.6%, respectively. Conclusion. The results of the study indicate that the width of the periodontal fissure is not the same in different parts of the root, varies depending on the functional load and does not depend on the group affiliation of the tooth. The width of the periodontal fissure at the level of transition of the upper third of the root to the middle third, the middle third of the root to the lower third and in the region of the apex of the root in the teeth on the lower and upper jaw, statistically significantly increases from the first period of adulthood to the second in both men and women.

Topography features of the incisive canal in early adults

Year: 2019, volume 15 Issue: №3 Pages: 690-696
Heading: Human anatomy Article type: Original article
Authors: Kalmin O.V., llyunina 0.0., Zyulkina L.A.
Organization: Penza State University
Summary:

Aim is to study topography of incisive canal depending on sex, parameters of craniofacial complex and dentition. Material and Methods. 174 adult persons of both sexes aged 21-35 years (first adult persons) (80 men and 94 women) were objects of the research. Garson facial index, upper face index and average modulus of maxilla were determined. Number of Stensen foramen and foramen incisivum, their sizes and shape; distances between foramen incisivum and inferior palatal and inferior labial point of maxillary alveolar process; length, shape, type and angle of inclination of incisive canal; bone density around incisive canal were determined on CBCT. Results. Size of nasal and incisivum foramen, length of incisive canal is significantly higher in men, and distances between foramen incisivum and inferior palatal and inferior labial points of alveolar process is significantly higher in women. Dimensions of heart-shaped foramen incisivum prevailed over sizes of droplet-shaped and oval foramen incisivum, and oval-shaped sizes were the smallest. Length of hourglass-shaped incisive canal was 3.4% higher than length of funnel-shaped canal, and 5.6% more than cylindrical shaped ones; length of spindle-shaped incisive canal was 12.7% higher than length of cylindrical canal. Conclusion. Incisive canal has individual variability of sizes, shape and topography depending on its shape and type, gender, cephalotype and average modulus of maxilla were determined.

Characteristics of masticatory apparatus reduction among population of Penza and Penza region

Year: 2010, volume 6 Issue: №2 Pages: 388-392
Heading: Stomatology Article type: Original article

Organization: Penza State University
Summary:

The research goal is to investigate regional characteristics of masticatory apparatus reduction of population of penza and penza region. 116 female and 98 male patients at the age between 21-36 were under study. According to the research results, mesio-distal reduction level of molars and incisors with sex factor was found out. Evaluation of teeth reduction indices was effected
