The research purpose:
А
longitudinal cohort study (from birth) regarding
the relationship between fluoride exposure, biological and environmental factors,
and oral health. Using data collected on dental caries and enamel hypoplasia in
deciduous teeth, this article reports on the relationship and differences between
enamel hypoplasia and caries.
Materials and methods:
Materials and Methods: for the medical research,
I’ve given a brief overview of caries and hypoplasia. With visual factors of their
discovery and a route to our purpose, namely, to capture some differences
between them.
Results and discussions:
hypoplasia Underdevelopment of hard tissues of
the tooth during their growth and formation Distinguish between systemic and
local hypoplasia Systemic hypoplasia is the result of various pathological
processes in the div, in which the function of ameloblasts, and often
odontoblasts, is impaired or inhibited, which leads to a violation of the
mineralization of enamel and dentin. Systemic hypoplasia of temporary teeth is
formed in the prenatal period and is associated with disorders in the div of a
pregnant woman. Systemic hypoplasia of permanent teeth is associated with
severe infectious diseases, rickets, digestive tract disorders, insufficiency of the
endocrine glands (especially parathyroid glands), metabolic disorders
Local hypoplasia is associated with a metabolic disorder in a localized area
near therudiments of permanent teeth, which occurs as a result of an
inflammatory process in theregion of the apex of the temporary tooth root or with
trauma to the developing follicle. It is more often observed on premolars, the
rudiments of which are located between the roots of temporary molars.
Hypoplasia develops as a result of the action of various factors: Endogenous
(abnormalities of embryonic cell priming) Exogenous (factors that adversely
affect the cells of the fetus or organ)

Hypoplasia must be differentiated from the initial and superficial forms of
caries. With hypoplasia, white spots are multiple, usually on symmetrical groups
of teeth, the surface of the tooth is smooth, not stained with dyes. With caries, the
white spot is single, more often localized in the cervical region, stained with a 2%
solution of methylene blue.
Prevention of systemic hypoplasia: Caring for the health of a pregnant
woman and a newborn Dental education in antenatal clinics and children’s clinics
Prescribing multivitamin complexes for pregnant women (“Pregnavit”)
Breastfeeding and good nutrition of the child, harmonious development
Prevention of infectious and non- infectious diseases in young children
Prevention of local hypoplasia is in the prevention of caries of temporary teeth or
its timely treatment in order to prevent the development of the inflammatory
process in the periodontium.
The cause of the appearance of this disease are microorganisms that are
present in the human oral cavity in many. First, the destruction of the enamel, and
then the dentin (the hard substance of the tooth), with further damage to the pulp
chamber, occurs under the influence of acids that these bacteria secrete in the
course of their life. and in the thickness of plaque, so periodic professional
cleaning of teeth is one of the most effective methods of caries prevention.
1. Signs of caries
2. Discomfort when the tooth comes into contact with sweet, sour, cold or hot.
3. Areas of darkening of the enamel.
4. Rough areas on the surface of the tooth.
5. Bad breath.
6. Formation of various defects in hard dental tissue.
7. Finally, pain, which indicates the development of acute caries.
Treatment of this pathology depends on the stage of its development. So,
with caries in the stain stage, it is enough to remineralize the enamel using special
solutions and pastes. And if the destruction of hard tissues has begun, then
mechanical cleaning of the cavity, the use of drugs that stimulate the restoration
of dentin, and the installation of a filling will be required.
How to distinguish hypoplasia from caries Hypoplasia appears immediately
when the tooth erupts, and caries – after a while on the initially healthy, uniform
color of the enamel. Hypoplasia is located in the region of the cutting edge or in
the middle of the tooth crown, and caries is closer to the gum or at the junction of
two adjacent teeth. With initial caries, chalky spots appear, they are located on the
contact surfaces and in the cervical region. Such spots do not have clear
boundaries, they can be pigmented, with a smooth, matte surface, and are stained
with dyes. Over time, their gradual progression occurs, ultimately resulting in a
defect in hard tissues and the formation of a cavity in the tooth.
Spots with enamel hypoplasia are multiple, they are localized over the
entire tooth surface, white, with a shiny, smooth surface, clear boundaries, they
are not stained with dyes. They appear immediately after teething.

In more severe forms of fluorosis, it is necessary to carry out differential
diagnostics with various lesions of a non-carious and carious nature: a wedge-
shaped defect, medium and superficial caries, erosions, etc.

MODERN ENDODONTICS AND FACTORS INFLUENCING

Endodontics is considered one of the most successful areas in dentistry.
With careful cleaning, shaping, debridement and obturation of the root canal
system, it is possible to achieve a successful outcome in the initial treatment in
approximately 94% of cases. With repeated endodontic treatment without signs
of apical periodontitis, this is possible in 89-96 %, and if they are present,
in 60-74%. At the current stage of endodontics, the size of the periapical lesion is
not the main factor in the decision to conservative endodontic treatment or
surgical removal of the lesion.
Due to the availability of instruments, equipment and treatment methods,
endodontic intervention should ideally end successfully. But when analyzing the
results of treatment, a number of publications noted that an unfavorable outcome
is noted even in the case of “well-treated canals”. In the current literature,
a successful long-term prognosis of endodontic treatment is associated with
intra- and extra-root factors.
Intraradicular factors include the complexity of endodontic anatomy,
infection, diversity of microflora in the root canal system, its resistance and ability
to organize into a biofilm. Non- root causes include extraradicular infection, "true"
cysts, the presence of endo- periodontal lesions, root resorption, the reaction of
periapical tissues to a foreign div (of endogenous or exogenous origin) and
iatrogenic factors (arising in the process of preparation, irrigation of the root
