Abstract:
Adhesive systems and resin composite materials have developed dynamically.
These materials have applied for an aesthetic reconstruction in posterior
teeth and this tendency has increased significantly over the last several
years. Student’s education is closely connected with learning and training
in clinical situation new technologies’ materials.
The purpose of this study was to investigate practical students skills
needed in aesthetic reconstructions of I and II class cavities by self-
etch Adper Prompt L-Pop Adhesive™ and universal nanocomposite Filtek Supråme™.
A clinical follow- up was conducted on 37 resins composite restorations
made in an undergraduate course over a 3-month period. It was investigated
proximal contact reconstruction, condensable resin composite abilities
and student’s efforts to obey clinical sequences in adhesive system application
according manufacturers.
The authors concluded that technically less- sensitive materials would
be suitable as the materials for undergraduate teaching programs where
less- experienced students are involved in the restoration work. Such
clinical follow- ups will help improve the teaching program and also provide
valuable insight into performance of the materials used.

- Plovdiv
Abstract:
We examine what anesthetic agents, from those currently available for
this purpose, are preferred in dental practice and are used in patients
with arterial hypertension. Data were gathered by questionnaires which
required information about the age, sex, specialty and place of work of
dental practitioners; it also included questions about blood pressure
measurement prior to dental treatment and subsequent selection of the
anesthetic agent to be used according to the obtained value. The most
preferred anesthetic agent was found to be ubistesine. Most of the respondents
(77.73%) tend to take the patient’s blood pressure if there is a history
of hypertension and the most frequently used anesthetic in such cases
was lidocaine.

ABSTRACT:
The surgical intervention needs sufficient analgesia. The authors share
their experience with on electroacupuncture (EAA) method in surgical treatment
of allergic predisposed patients (man and women, age 25 – 60). The authors
influence over 3 facial located acupuncture points and 2 distal bodies-
located with OZ-22 (EAA-apparatus) for 20 – 25 min before the surgical
intervention. The anesthesia rate, reactions of patients and the major
vital parameters are observed, measured and evaluated with special score.
Total or partial analgesia was found in 55% (10 patients).
The main characteristics of the EAA are low price, easy management, nontoxic
and noninvasive technique. The authors considered EAA as a method of choice
for patients with medication allergies and somatic chronic diseases.

Plovdiv
ABSTRACT:
The aim of the present study was to evaluate intraligamentary anesthesia
as it is used in general dental practice. Material and methods: The study
included 220 dental practitioners throughout Bulgaria who were interviewed
anonymously using a direct group questionnaire survey. We analysed problems
primarily related to the application, analgesic effect and complications
of the anesthesia. The results of the study have shown that 75.91% of
Bulgarian dental practitioners use intraligamentary anesthesia in almost
all types of dental treatment. Complications were found to occur in 27.54%.
The anesthesia was sufficiently effective only in 32.94%. Conclusion:
Intraligamentary anesthesia is used frequently by Bulgarian dentists.
The effect of this type of anesthesia is not always sufficient to induce
effective analgesia and very often additional anesthetic procedures are
necessary.

Sofia
SUMMARY: The presence of microorganisms and derivative
toxins in the infected root canals determine the changes that occur in
the apical periodontium.
The aim in this in vitro study has been to evaluate the antimicrobial
activity of the intracanal medicaments against bacterial isolates in cases
with acute periapical periodontitis.
The following clinical isolates from cases with
acute periodontitis (nonexudative form) were used in the present study:
Streptococcus pyogenes, Streptococcus mitis, Streptococcus bovis, Streptococcus
anginosus, Enterococcus faecalis, Staphylococcus aureus. We tested their
sensitivity to some of the most frequently used intracanal medicaments
(in vitro), i.e.: Calcium hydroxide paste (Calcident 450® W/P Dental,
Germany), Sodium hypochlorite 3% (Switzerland), Metronidazole 0.5% (Troya
Pharm, Bulgaria), Chlorhexidine gluconate 0.1% (Troya Pharm, Bulgaria),
and a combination of Sodium hypochlorite 3% and Metronidazole 0.5%.
The results show that Calcium hydroxide had the strongest impact in direct
contact with the studied microorganisms, followed by Chlorhexidine gluconate
0.1% and Sodium hypochlorite 3%. The combination of Sodium hypochlorite
3% + Metronidazole 0.5% is more active than Metronidazole 0.5% used on
its own.

SUMMARY: Denture stability is of primary importance for
the successful result of the prosthetic treatment of totally edentulous
patients. The authors aim was to present their methods for selecting posterior
artificial teeth form by patients with compromised stability of the full
dentures. After a profile teleroentgenography and measuring the condylar
pathways and its angle to the Camper’s line, different sets of posterior
tooth form of artificial teeth were chosen- Orthocal, Artic (20? ) or
Basic (30? ), Heraeus Kulzer, Gmbh&Co.KG. The new prosthetic treatment
showed very good stability of the full dentures at function assessed by
the patients themselves and checked by the clinical tests.

Bulgaria
ABSTRACT: Introduction. The maxillary and the mandibular
anatomic casts of full dentures impressions should include all the anatomic
surfaces of the anatomic impression as an appropriate individual tray
to be performed.
The purpose of the authors is to present the most often mistakes by anatomic
casts of full dentures’ first impressions made in the Prosthodontics’
exercises in the clinics of Prosthodontics, Faculty of Stomatology-Sofia
by the students.
Materials and methods.On critical observation were subjected 48 anatomic
casts (26 upper and 22 lower casts) of 28 patients (16 women and 12 men)
with a forthcoming full dentures’ prosthodontic treatment. The results
show that 37, 5% of the anatomic casts didn’t meet the requirements of
an appropriate stone cast.
Discussion.The observed shortcomings and defects by the false casts draw
our attention on the necessity of more detailed and well grounded explanation
of oral anatomy in connection with the future role of the anatomic stone
casts for the retention and stability and construction of the full dentures.

SELECTIVE PRESSURE IMPRESSIONS METHODS FOR TOTAL
DENTURES BY PATIENTS WITH LOOSE AND HYPERMOBILE MUCOSA ON THE ALVEOLAR
RIDGES
Hr. Hadjieva, M. Dimova
Dept. of Prosthodontics, Faculty of Stomatology, Medical University-Sofia,
Bulgaria
ABSTRACT: Introduction. The mucosa over the alveolar
ridges by totally edentulous patients is with varying thickness and mobility
at different places and is distorted at the time of impression procedure.
This distortion duplicated in the finished dentures causes inflammation
and instability of the dentures.
The aim of the authors is to present three methods for selective pressure
impressions for total dentures’ treatment by patients who had different
kind of localization and abnormalities of the thickness and mobility of
the alveolar ridges’ mucosa.
Materials and methods .15 edentulous patients, 9 women and 6 men, mean
age 64 years, with different kind of mucosal abnormalities were divided
into three groups and treated with full dentures. Three different impression
techniques are used for selective pressure impressions.
Results. The silicone pressure tests at the delivery appointment showed
even layer of the material over the base plate of the dentures, except
for two patients from the first group. with The patients mention for comfort
and satisfaction during the usage of the new dentures, compared with the
previous one.
Discussion. The secondary impression causes some displacement no matter
how carefully is made. The suggested three methods eliminates the excessive
displacement of the soft tissues at the secondary impression thus a physiologic
and anatomic registration of the attached and the unattached tissue of
the denture bearing areas are attained.
Key words: total dentures treatment, hypermobile tissues,

TOTAL REHABILITATION BY EDENTULOUS PATIENTS WITH
IRREGULARITY OF THE ALVEOLAR RIDGES
Hr. Hadjieva, M. Dimova
Department of Prosthodontics, Faculty of Stomatology, Medical University
- Sofia, Bulgaria
ABSTRACT: Introduction. The treatment of edentulous patients
is always a challenge for the prosthodontists. It is connected with a
lot of procedures aiming to reconstruct and replace the lost natural dentition
and associated structures of the mandible and maxilla for patients who
have lost all their remaining teeth. The basic objectives of complete
denture Prosthodontics are the restoration of function, facial appearance
and the maintenance of patient’s health.
The aim of this work is the prosthetic treatment of patients with asymmetry
of alveolar ridges, the difficulties connected with that treatment and
the suitable techniques and approaches to overcome those problems.
Material and methods. Twenty patients, twelve women and eight men, with
an average age of 64±7 years were included in this investigation. All
of them had different type and degree of irregularity of the alveolar
ridges. The complaints of the patients were mainly connected with poor
denture stability during mastication and with the esthetics. The treatment
strategy of those patients included excellent impression of the peripheral
seal, very careful measurement of the parameters of the vertical and horizontal
occlusal plane, lingualized occlusion and esthetics improvement procedures.
Results: All the twenty patients accepted the new dentures with comfort
and esthetical satisfaction and assessed them to be significantly more
satisfying in esthetic appearance, maxillary and mandibular denture retention
and chewing ability. To six of them preliminary contacts were eliminated
at the delivery appointment. On the second appointment by 3 patients from
the third group and one from the first group decubital ulcers were treated.
Conclusion. As complete dentures are the last consideration for the patient
(excluding implant treatment) they must be designed and constructed with
an emphasis on the preservation of the remaining structures.
Key words: denture retention, denture esthetics, irregularity
of the ridges, edentulousness
