ABSTRACT 

Non-carious dental lesions are a frequent occurrence in dental practice. This concept includes a wide range of diseases 

with different etiologies and clinical manifestations.Non–carious dental lesions are an extensive group of diseases and 

pathologies. These include all damage to enamel, dental tissue, diseases of a non-bacterial nature. 

KEYWORDS 

Pathology, teething, non–carious, diagnose, hyperplasia, fluorosis. hereditary pathologies, tooth injury, pigmentation. 

INTRODUCTION

In terms of prevalence, they occupy the second place 

after caries. Such lesions can have a variety of 

symptoms and clinical picture, and they have different 

causes of occurrence. But they are all congenital or 

acquired. They can have different distribution – they 

affect one or all teeth in a row, separate areas in a 

certain order. Many of these diseases are difficult to 

diagnose, since the signs of different pathologies are 

similar and difficult to distinguish from each other. This 

may also be due to insufficient knowledge of the 

disease, which complicates its detection and increases 

the risk of complications.

Classification of non-carious lesions 

Due to the variety of diseases that belong to the 

concept of "non-carious lesions of the teeth", their 

classification does not have one generally accepted 

standard. If you summarize all the data, you can get a 

generalized list of types of lesions. 

1. Pathology of development during teething: Anomaly 

of shape, size. Fluorosis (speckled teeth). Enamel 

hypoplasia (developmental disorder). Pathology of the 

structure of teeth of a hereditary nature 

(odontogenesis, amelodentinogenesis). Syphilis 

(congenital). Other developmental pathologies 

associated with external factors (taking antibiotics, 

rhesus conflict). 

2. Pathological changes in the hard tissues of the tooth: 

Complete loss of the tooth. Erosion. Color change after 

eruption. Hypersensitivity of tissues. 

3. Changes in the internal structure of the tooth: Root 

fracture. Dislocation of the root. Fracture of the tooth 

crown. Opening of the pulp. In our country, another 

classification is more often used, proposed in 1968 by 

V. K. Patrikeev. According to it, non-carious lesions of 

the teeth are divided into two groups. 

4. Lesions that occur before eruption: An anomaly of 

eruption and development. Hypoplasia of teeth. 

Hyperplasia. Fluorosis. Hereditary pathologies. 

5. Lesions that occur after eruption: Erosion. Wedge-

shaped defect. Necrosis of hard tissues. Hyperesthesia 

of teeth. Erasure. Tooth injury. Pigmentation. 

Hypoplasia. 

This is the name of the pathology of the development 

of dental tissue during its formation, that is, in children 

before teething. Such a violation is caused by 

insufficient mineralization of tissues. The main sign is 

the complete absence of an organ or its abnormally 

small development. Hypoplasia of teeth can be both 

congenital and develop after the birth of a child. There 

are several reasons for this: the conflict of Rh factors 

of mother and child, an infectious disease suffered by 

the mother during pregnancy, infections in the child 

after birth, severe toxicosis accompanying pregnancy, 

premature birth, trauma during childbirth, pathology 

of the child's development after birth, dystrophy, 

diseases of the gastrointestinal tract, metabolic 

disorders, developmental disorders brain activity, 

mechanical damage to the jaw bone. There are two 

types of hypoplasia – systemic and local. The first is 

characterized by the defeat of all teeth, low enamel 

thickness or its absence. Yellow spots appear. Local is 

characterized by the defeat of one or two organs. 

There is a lack of enamel (partial or complete), 

structural defects of teeth – they can be deformed. 

Such violations cause pain. Severe hypoplasia causes 

increased tooth abrasion, tissue destruction or 

complete organ loss, and the development of 

malocclusion. Treatment of hypoplasia includes teeth 

whitening (at an early stage) or filling and prosthetics 

(with severe disease). At the same time, the enamel is 

remineralized with medical preparations (for example, 

calcium gluconate solution). In order to prevent the

occurrence of hypoplasia in children, pregnant women 

are recommended a balanced diet containing vitamins 

for teeth (D, C, A, B), calcium and fluoride, as well as 

strict observance of oral hygiene. 

Hyperplasia 

Hyperplasia – non-carious lesions of the teeth 

associated with excessive formation of tooth tissues. 

Their appearance is caused by an anomaly in the 

development of epithelial cells, enamel and dentin. It 

manifests itself in the form of "drops", which are also 

called "enamel pearls". They can reach 5 mm in 

diameter. The main area of localization is the neck of 

the tooth. Such a drop consists of tooth enamel, inside 

there may be dentin or soft connective tissue 

resembling pulp. There are five types of such 

formations according to their structure: true-enamel – 

consist only of enamel, enamel-dentine – the enamel 

shell contains dentin inside, enamel-dentine drops with 

pulp – connective tissue is inside, Rodriguez-Ponti 

drops – enamel formations in the periodontium 

between the root and the alveolus, intra–dentine - 

located in the thickness of the dentin. Hyperplasia of 

dental tissues does not manifest itself clinically in any 

way, it does not cause pain, inflammation or any 

discomfort. It is only possible to single out an aesthetic 

factor if the anomaly affects the front teeth. In this 

case, grinding and leveling of the surface is carried out. 

In other cases, if nothing bothers the patient, 

treatment is not carried out. Preventive measures are 

to protect baby teeth from caries, since their 

destruction can cause disturbances in the 

development of permanent ones. 

Fluorosis 

Fluorosis occurs during the formation of dental tissue 

due to increased intake of fluoride into the body. It 

changes the correct structure of the enamel and 

causes its external defects – the appearance of spots, 

stripes, furrows, dark inclusions. In the development of 

such pathology, not only an overabundance of fluoride 

plays a role, but also a lack of calcium. In the child's 

body, fluoride accumulates more and faster than in 

adults, coming with food and water. There are such 

forms of fluorosis: dashed – manifested by the 

appearance of white stripes without a clear contour; 

spotted – characterized by the presence of yellowish 

spots with a smooth surface; chalky-speckled – matte 

or shiny spots having a white, brown or yellow color 

(can affect all teeth); erosive – multiple erosion of the 

enamel surface; destructive (a tooth has broken off or 

completely collapsed) – harmful processes 

accompanying fluorosis. Methods of treatment of 

fluorosis vary depending on the form of the disease. 

So, with a spotty form, bleaching and remineralization 

is carried out, if necessary, grinding of the top layer of 

enamel. But the erosive form cannot be cured in such 

ways, it is necessary to restore teeth with veneers or 

crowns. General methods of treatment include 

remineralization, restoration of the shape and color of 

the organ, local effects on the body, control of fluoride 

intake.

Erosion 

Non-carious lesions of the teeth include such damage 

to the enamel as erosion. Its formation leads to 

discoloration, aesthetic damage to the tooth, as well as 

increased sensitivity. It is detected by visual inspection. 

Tooth erosion is characterized by progressive 

destruction of enamel and dentin, the course of the 

disease is chronic, can take a long time. The cause of 

the pathology may be mechanical, for example, when 

using hard brushes or pastes with abrasive particles. 

Also, erosion can be caused by chemical effects on the 

enamel when eating foods and beverages with high 

acidity (pickles, marinades, citrus juices and others). 

Production workers associated with the constant 

inhalation of harmful substances most often suffer 

from such a lesion of the teeth. The use of certain 

medications can contribute to the onset of the disease 

(for example, a large amount of ascorbic acid has a 

detrimental effect on the enamel). 

The cause of tooth erosion can also be disorders in the 

work of the stomach (increased acidity of its 

environment) or the thyroid gland. It is difficult to 

identify the disease at an early stage, since it manifests 

itself only by the loss of shine on a separate small area 

of the tooth. The further course of the disease leads to 

a gradual decrease in enamel and dentin. It looks like 

worn teeth, most often at the base. Treatment is based 

on stopping the destruction of dental tissues. It 

includes the use of applications containing fluoride and 

calcium for about 20 days, then the affected area is 

covered with fluorolac. It is possible to use veneers or 

crowns to restore an aesthetic appearance. The 

complex therapy includes calcium and phosphorus 

preparations, as well as vitamins for teeth. If erosion is 

not treated, it can cause hyperesthesia of the teeth. 

Hyperesthesia 

Hyperesthesia of teeth is manifested by increased 

sensitivity of the enamel and in most cases is a 

concomitant symptom of other non-carious diseases. 

The prevalence of this pathology is high: about 70% of 

the population suffer from hyperesthesia, women are 

more prone to it. The manifestation is a sharp, severe 

pain that lasts no more than thirty seconds and 

appears when external factors affect the enamel. 

Hyperesthesia is divided into types according to 

several criteria: 

1. Distribution: limited form - affects one or more teeth; 

generalized - characterized by sensitivity of all organs. 

2. Origin: a form of hyperesthesia associated with the 

loss of dental tissues; not associated with loss, due to 

the general condition of the body.
