Algunos factores coadyuvantes del bienestar del niño y su relación con la
salud bucal.
Some coadjutant factors of child’s wellbeing and their relation to oral health
ABSTRACT
OBJECTIVE: to determine the relation existing among some indicators influencing on
oral health during childhood.
METHODS: an analytical case and control study was conducted in the municipality of
Bauta, Havana province, from June 2005 to June 2006. The universe was composed of
2 408 children aged 2-5. A sample of 400 children was taken from it. The following
variables were used: oral health status, birth weight, gestational age and
maternal
breastfeeding. The odds ratio was obtained whenever it was possible for the variables
whose association with the oral health state proved to be significant aimed at
identifying the increase or reduction of the probability of having a poor oral health in
the presence of the risk factors taken into account.
RESULTS: 10 % of the low birth weight children had an affected oral health state, 6.5
% of the preterm children were considered cases, and oral health declined in 39.5 % of
the children that were not breast-fed.
CONCLUSIONS: low birth weight and the non-maternal lactation affect the oral health
state, but gestational age does not.
Key words: oral health, birth weight, gestational age, maternal lactation.

Xerostomía y uso de medicamentos en adultos.
Xerostomia and the use of drugs in adults
ABSTRACT
OBJECTIVE: to determine the prevalence of xerostomia in connection with the use of
drugs in adults aged 20 and over at the Family Physician’s office 64-02 in Guanabacoa
from July to December 2007.
METHODS: a descriptive study was undertaken and a bistage sampling was used. The
presence of xerostomia based on the definition used by other authors was determined
by 3 questions in addition to age, sex, use, amount and type of drugs according to the
questionnaire.
RESULTS: the information was processed in Excel, using percentage to resume it. The
results were presented in tables. The variables were related to X2 and the difference of
proportions (p<0.05) by using the Epidat program. Of 511 studied individuals, 176
(34.4 %) perceived xerostomia. Females were the most affected. It increases with age,
and the group aged 60 and over was the most affected.
CONCLUSIONS: the most used drugs were the antihypertensive and antiasthma drugs.
All those who took glycemia-lowering and antiallergic drugs perceived xerostomia and
it rose according to the number of drugs used.
Key words: xerostomia, dry mouth,drugs.

Relación del estado de salud bucal con algunos factores socioeconómicos en
niños de 2-5 años.
Relation of the oral health state to some socioeconomic factors in children
aged 2-5
ABSTRACT
OBJECTIVES: to determine the association of some risk factors with the oral health
state in the early childhood, to identify the connection of the oral health of these
children with oral hygiene, the type of diet, parents’ educational level and
parents’
job.
METHODS: a 2-stage study was carried out in Bauta municipality, Havana province
from June 2005 to June 2006. The first stage was descriptive and cross-sectional, and
the second was analytical according to the case-control methodology (200 children of
each type).
The following variables were used: oral health state, educational level,
parents’ occupation, oral hygiene and type of diet.
RESULTS: the behavior of oral hygiene was inadequate in 39.5 % of the cases and in
5.5 % of the controls. The cariogenic diet prevailed in the case group (65.0 %),
whereas the acceptable diet increased in the control group (44.0 %). As regards the
influence of educational level on the oral health state, the result did not show
statistical significance.
CONCLUSIONS: the adequate oral hygiene and the non-cariogenic diet rose the
possibility of having an appropriate oral health state. The educational level and the
occupation of the parents had no correlation with the oral health of their children.
Key words: oral health state, parents’ educational level, parents’ occupation, oral
hygiene, cariogenic diet.

Estudio in vitro sobre los efectos de la cocaína sobre los tejidos duros del
diente.
In vitro study on the effects of cocaine on the hard tissues of the tooth
ABSTRACT
The use of cocaine derivatives is an increasingly growing public health problem. These
drugs are frequently rubbed on the gingival mucosa, but their efffects are little known
and difficult to be diagnosed. This paper pretends to prove in vitro that the rubbing of
cocaine on the dental surface produces enamel erosion. 30 healthy teeth were selected
and distributed at random into 3 groups that were rubbed cocaine hydrochloride,
bazuko and lemon (control group) on the vestibular surface, respectively, during 40
weeks. The most observed characteristic lesions were fracture and loss of the dental
hard substance, which showed that the topical and continual application of
drugs on
the oral cavity causes lesions in the hard tissues of the tooth.

Exodoncias dentarias e interferencias oclusales postratamiento ortodóncico.
Dental extractions and occlusal interferences postorthodontic treatment
ABSTRACT
A study of 20 patients under 30 years old discharged from the Orthodontics Service of
the Faculty of Stomatology of Havana City was conducted to evaluate the influence of
some
morphological
variables
as
the
canine
relation,
contact
in
maximum
intercuspidation position (MIP), overbite and overjet. The study revealed the
predominance of patients with occlusal interferences that were more frequent in the
group with no dental extractions. Most of the patients presented canine neutroocclusion; however, both groups showed a great percentage of occlusal interferences.
In the group with extractions, the contact in MIP of the anterior teeth was mostly
attained in the group with extractions. In all the corresponding movements the
interferences were more frequent in the working area. It was observed a prevalence of
anterior canine overbite of 1/3 of the crown, but the occlusal interferences
predominated in the same way, mainly in the group without extractions.
Key words: functional occlusion, occlusal interferences, centric relation, maximum
intercuspidation position,

La formación para la investigación en el perfil de carreras de Estomatología
de universidades latinoamericanas.
The research training in the profile of Stomatology careers of Latin American
universities
ABSTRACT
Universities are the vertebral column of the scientific-technological subsystem of each
country. That’s why, they should stimulate the creative spirit as well as the scientific
training of the professionals they educate. It is necessary that the objectives directed
to the research training of the students appear in an explicit way in the profile of the
stomatology careers not only for the future professionals to contribute to the solution
of the oral health problems and to improve the quality of the persons’ life, but also
because a university research giving concrete solutions to the health problems of social
impact is necessary. Starting from the previous premises, a documentary study was
carried out aimed at verifying the presence of research training in the Stomatology
career of 18 Latin American universities, including the profile of the Stomatology
career of Cuba, for which a bibliographic research was made in Internet that allowed
the review and analysis of such profiles.
As a result, it was observed that of the 18
studied profiles, only in 6 (33.3 %) an objective directed to the research training of
the future stomatologists is well-defined, and in 12 (66.6 %) it does not exist. It was
concluded that in most of the consulted professional profiles of the Stomatology
career, their research training is
not included in the graduate profile. The
improvement of such curricula with the inclusion of the investigative component and its
explicit presence in the professional profile is necessary.
Key words: research training, Stomatology career, professional profile.

Evaluación del distalador molar Belussi.
Evaluation of Belussi’s molar distalizer
T
ABSTRACT
The distalization of the superior molars in mesial migration is a useful
treatment
alternative
nowadays. Many methods of molar distalization are known. They have
significantly evolved and they are still effective in the treatment. The objective of this
investigation was to evaluate the dental changes produced
by Belussi Molar
Distalizer. The appliance was used in 11 patients with an average of 12 years-old,
distoocclusion of molars caused by mesial migration and with a favorable facial type.
Study models were made for each one of them and pictures, panoramic x-rays and
lateral X-rays of the skull were taken, before and after the treatment, to analyze the
variables object of study. The appliance was kept in the mouth until achieving an
overtreatment of the
molar relation. Finally, a molar distalization of 4.45 mm
accompanied with an inclination of 5.55° was obtained, with a minimum loss of
temporary anchorage.
Key words: mesogression, distalization, vestibuloversion, Belussi’s molar distalizer.

Agenesia de terceros molares en pacientes de la Facultad de Odontología de
la UNAM.
Agenesia of the third molars in patients of the Faculty of Odontology of the
National Autonomous University of Mexico
ABSTRACT
ANTECEDENTS: the third molars are the last teeth to erupt. Their presence generate
diverse pathologies as crowding, pericoronitis and pain, generally due to the lack of
space in the maxillae. According to human phylogeny, they are considered teeth on the
way to extinction. They present an increasingly delayed eruption and even absence
due to lack of formation,
OBJECTIVE: to determine the frequency of agenesia of the third molars in patients of
the Faculty of Odontology of the National Autonomous University of Mexico.
METHODS: 915 orthopantomographies of patients aged 16-24 were examined and the
diagnosis of presence of the third molars was made. Sociodemographic information
was necessary and the association with sex was analyzed by using X2.
RESULTS: 20 % of the sample presented agenesia of the 4 third molars, 56 % had the
4, and 24 % only from 1 to 3. Besides, it was found that sex does not determine the
presence of the third molars (X2= 0.503, p= 0.478).
CONCLUSIONS: the frequency of agenesia of the third molars was 20 % and it is
independent of sex.
Key words: third molar, frequency, agenesia.

Glucanos extracelulares bacterianos: estructura, biosíntesis y función.
Extreacellular bacterial glucans: structure, biosynthesis and function
ABSTRACT
Dental caries is one of the most common diseases in the human being. Certain
cariogenic bacteria play an important role in its multifactorial etiology, since in their
interaction with the dental surface they promote its demineralization. The production
of extracellular bacterial polyssacharides is among the mechanisms mediating
bacterial adhesion. The glucans synthesized by glycosyltransferases not only allow the
adherence, but they also are a nutritional source for bacteria and that’s why the
activity of such enzymes is considered a factor of bacterial virulence in dental caries.
This bibliographic review is aimed at making clear the aspects related to the structure,
biosynthesis and function of glucans and at giving emphasis to the application of this
knowledge in the prevention of dental caries.
Key words: glucans, glycosyltransferases, dextran, mutan, biofilm, dental plaque.

Osteomielitis crónica esclerosante difusa: a propósito de un caso.
Chronic diffuse sclerosing osteomyelitis: apropos of a case
ABSTRACT
Diffuse
sclerosing
osteomyelitis
is
considered
a
chronic
primary
osteomyelitis
consisting in an inflammatory, painful and prolonged process. It only affects the
mandible and it is generally unilateral. It involves the basal and alveolar bone and it is
located at the level of body, angle, branch and even condyle. The cause is more
controversial, since some attribute an infectious origin to it, whereas others consider it
as a non-infectious condition resulting from the overloads or associated with SAPHO
syndrome (synovitis, acne, pustulosis, hyperostosis and osteitis), but literature is not
concluding. Treatment as well as its cause are not totally clear. Different alternatives
are described that go from the conservative to the most radical position. The 7-month
follow-up and treatment
of a female patient suffering from diffuse sclerosing
osteomyelitis with approximately18 years of evolution that has been refractory to the
conventional therapeutic alternatives is presented.
Key words: sclerosing osteomyelitis, osteomyelitis, mandible.

Mixoma odontogénico, un reto para el diagnóstico. Presentación de un caso.
Odontogenic myxoma, a challenge to diagnosis. A case report
ABSTRACT
The case of a 41-year-old male white patient who smokes and drinks alcoholic
beverages and that on the physical examination manifests a rosette-like tumoral lesion
of 3.3 cm of diameter that ocuppies the edentulous area of the inferior right alveolar
crest of the mandible corresponding to the first and second molars is presented. In the
panoramic radiography, it was observed a radiolucid multiocular area that respects the
border of the mandible with an irregular cortical in some areas.
An odontogenic
myxoma was histopathologically diagnosed by using hematoxylin and eosin staining.
The patient was surgically treated and the diagnosis was confirmed by alcian blue
staining, which yielded positive. As the odontogenic myxoma is a tumor with neither
clinical nor pathognomic radiographic characteristics, inaccurate symptoms, local
aggresive behavior and frequent relapses, it should always be taken into account in the
differential diagnoses of the tumors of the maxilla and the mandible.
Key words: myxoma, odontogenic tumors, neoplasia.
