EMERGENCY TREATMENT OF IRREVERSIBLE PULPITIS
Elka Radeva
Department of Conservative Dentistry, Faculty of Dental Medicine, Medical University - Sofia , Bulgaria
Summary:
Irreversible pulpitis is characterized by acute and intense pain that is difficult to control with painkillers; hence the patient needs urgent endodontic help
The aim of this study has been to determine the minimum set of interventions needed in order to reduce the pain and prevent further complications when treating emergency cases of irreversible pulpitis.
The study encompassed 102 endodontic cases. After being diagnosed as advanced irreversible pulpitis, the cases were divided into 3 groups depending on the manipulations.
The results show that the minimum set of interventions leading to a satisfactory clinical result, to a lower percentage of bleeding in the root canal and pain at percussion, was the one in Group 2.
The best clinical results were achieved by Group 3, but frequently, due to the lack of time within a single appointment, it is impossible to implement all manipulations in this group.
Key words : emergency treatment, intracanal medicaments, irreversible pulpitis

EXAMINATION OF PALATAL MUCOSAL RELIEF IN NORMAL OCCLUSION PATIENTS
Vera Krumova
Department of Orthodontics, Faculty of Dental Medicine, Medical University - Sofia , Bulgaria
Summary:
Although its discussional stability, the position of primary rugae distal edges was examined for two reasons: on one hand, it was provoked by Van der Linden’s clinical study on the stable and constant position of the first rugae in relation to canines and on the other, by the lack of published research results on this issue in Bulgarian medical literature. From anatomo-topographic point of view, the first rugae are disposed just behind sutura incisiva with its onset between the lateral incisives and canines. Most frequently, the first ruga is fastened to the palatal suture on a quite large basis. Having in mind that the palatal mucosa and teeth have common ectodermal origin and the genetic determination of relief reveals yet in embryonic development, the elucidation of the relationship between them is of special interest. Our study on first ruga position determining the commencement of rugal zone aimed at establishing the stability of rugal position in orthodontically non-treated Class I intact dentitions and at its possible use as a reference for comparisons. Our study used the classical anthropologic method of Martin-Saller and the method of Jordanov. The study group included 80 Bulgarian students at the Faculty of Dental Medicine, Medical University – Sofia, from both sexes (42 males and 38 females) with intact dentition and normal occlusal proportions – Class І (orthognatic occlusion) and non-treated orthodontically. The analysis of mucosal relief components showed that three shapes of papilla incisiva were most commonly observed: oval (31.3%), pear-shaped (23.8%) and flame-shaped (17.5%). This corresponded with the shape types and respective frequencies found by the population study among Bulgarians. The analysis of the type of rugal zone relief showed that in normal occlusion subjects, type A (three primary rugae) was mainly observed. These data were similar to those obtained for adult Bulgarians. The distal border in normal occlusions was rather symmetric than asymmetric. Our research data for the medial rugae disposition in relation to canines revealed that almost 1/2 of the cases (38) (47.5%) displayed bilaterally symmetric disposition of medial (primary) ruga against the canine tooth. The medial (primary) rugae were projected in right in 92.6% of the cases and in left in 87.8% of the cases, within the limits of the canine mesiodistal diameter as the significant frequency of this position give grounds for its acceptance as a norm/reference. .

Hristina Mihailova
Department of imaging and oral diagnostic, Faculty of Dental Medicine, Medical University - Sofia, Bulgaria
ABSTRACT:
There are a lot of reports in the literature concerning a wide variety of imaging modalities used for the diagnostic process of mandibular fractures. They include plain radiography, CT, MRI, radionuclide imaging. Because all of these examinations cannot be used simultaneously imaging algorithms should be developed. That will allow early diagnosis of the mandibular fracture to be made.
This issue focus on which imaging modalities to use and when to use them in the diagnostic process of mandibular trauma.
Key words: mandibular fracture, radiograms, algorithm

Christina Popova, K. Kotsilkov
Department of Periodontology, Faculty of Dental Medicine, Medical University - Sofia, Bulgaria
ABSTRACT:
Marginal tissue recession is a displacement of the soft tissue margin apical to the cement-enamel junction with exposure of the root surface. The etiology of the gingival recessions is associated with the gingival inflammation, mechanical factors like improper toothbrushing in the circumstances of tooth malposition, bone dehiscence, thin periodontal tissue, and aberrant frenulum. The treatment of the gingival recession in the last years includes gingival grafting procedures. The most generally used procedure is the free gingival graft. Recent studies have demonstrated that connective tissue grafting is an effective treatment of gingival recession. The graft used may either be an epithelialized graft or a subepithelial connective tissue graft of palatal masticatory mucosa.
The presentation demonstrates an connective tissue graft procedures for root coverage in a 23 years old patient with Miller class II recessions on teeth #14, #15, #24, and Miller class I recessions on teeth #16, #25, #26 and the results.
In the limitations of this case the connective tissue graft procedure led to clinical improvement which is a premise for better maintenance of the achieved root coverage

FREE GINGIVAL AUTOGRAFT FOR AUGMENTATION OF KERATINIZED TISSUE AND STABILIZATION OF GINGIVAL RECESSIONS
Christina Popova, Tsv. Boyarova
Department of Periodontology, Faculty of Dental Medicine, Medical University - Sofia, Bulgaria
ABSTRACT:
Background: The presence of gingival recession associated with an insufficient amount of keratinized tissue may indicate gingival augmentation procedure. The most common technique for gingival augmentation procedure is the free gingival autograft.
The aim of this study was to evaluate the changes in the amount of keratinized tissue and in the position of gingival margin in sites treated with free gingival autograft apical to the area of Miller’s class I, class II and class III gingival recessions.
Methods: Twenty three subjects with 56 gingival recessions associated with an insufficient amount of keratinized gingiva were treated with gingival augmentation procedure (free gingival graft). The grafts were positioned apical to the area of recession at the level of mucogingival junction. Clinical variables, including recession depth (Rec), amount of keratinized tissue (KT) and probing depth (PD) were measured at baseline and six months to one year after surgery and analyzed using statistics model of variation analysis.
Results: From baseline to one year after free gingival grafting KT increased with 4.28±1.10 (P<0.001) and recessions reduced with 0.90±0.56 (P<0.001). There was no significant change in probing depth after gingival augmentation procedure (P>0.05).
Conclusion: In the limits of this study it may be concluded that free gingival graft augmentation procedure apical to the area of recession lead to predictable results providing an increased amount of keratinized tissue and may reduce the recession depth.
Key words: Gingival recession; free gingival graft; gingival augmentation procedure.

Christina Popova, Antoaneta Mlachkova, D. Emilov
Department of Periodontology, Faculty of Dental Medicine, Medical University - Sofia, Bulgaria
Background:
Diagnosis, treatment and long-term retention of the furcation involved molars in chronic periodontitis patients always have been challenge to the periodontal specialist. Continued periodontal breakdown in the furcation area may lead to total loss of the tooth unless these defects can be predicted, diagnosed and appropriate treated to preserve as long as possible the entire dentition. Two important risk factors for progression of periodontal disease – furcation involvement and pocket depth – are implicated in multi-step process of the calculation of the risk (PRC) (2).
The demonstration of the association between actual pocket depth in molar sites and interradicular deterioration would be of great importance in suggesting treatment options for minimizing future risk for progression of the bone loss in furcation involved teeth (3, 4).

EFFECTIVENESS OF NSAIDs AULIN AND IBUPROFEN ON THE POSTOPERATIVE PAIN AT GINGIVAL GRAFT PROCEDURES – A PRELIMINARY STUDY
Christina Popova, Antoaneta Mlachkova, D. Emilov
Department of Periodontology, Faculty of Dental Medicine, Medical University - Sofia, Bulgaria
ABSTRACT:
Background: Gingival reconstruction has recently become a routine part of the periodontal treatment. Gingival grafting is considered as predictable procedure for root coverage with a high degree of cosmetic enhancement for attached tissue augmentation and for preprosthetic treatment. Mucogingival surgery includes pedicle flaps and free gingival grafts or connective tissue grafts. These procedures are accompanied by donor site pain. NSAIDs are successfully used to affect this pain. Aulin and Ibuprofen have good analgesic and anti-inflammatory activities. Their main pharmacological action includes inhibition of prostaglandin synthesis via COX-2, reduction of cytokine-induced hyperalgesia by suppressing TNF-± and the synthesis of proteinase enzymes (MMPs). Postoperative administration of the drugs after gingival graft procedures and its pharmacological effect might contribute to inhibit the pain and decrease the morbidity in the postoperative period.
Methods: Fifteen subjects participated in this study from 18 to 62 years of age. They received Aulin and Ibuprofen twice daily x 100 and 200 mg respectively for 4 days – in the early postoperative period. The surgical interventions were performed under local anaesthesia (4% Ubistesin with epinephrine 0,006 mg/ml). A four-point verbal rating scale (VRS-4) was used to measure the level of pain. Patients were instructed to complete a pain diary every hour for the first 8 hours after the surgical procedure and three times a day on the following 3 days. Each of them received Aulin or Ibuprofen initially by the end of the first hour after intervention and 12 hours after the first dose, and then for the next 3 days twice daily x 100 and 200 mg, respectively. Patients evaluated an independent rate of their pain intensity as follows: high expression, moderate, discomfort or missing.
Results: In the following hours after the grafting procedure the pain in the recipient and donor sites show scores of successful inhibition from 0.33 to 1.25. This represents discomfort to missing pain. In the first day after the surgery Aulin® shows higher scores than Ibuprofen® but both of them are lower than 1, which represents discomfort to missing pain. In the second day, the pain shows a little bit higher scores. In the third day, the pain is successfully inhibited and the pain syndrome is still between discomfort and missing pain.
Conclusions: Aulin® and Ibuprofen® are effective analgesics in the early postoperative healing – there was no need for additionally analgesic drug to be taken .
Key words: cosmetic gingival reconstruction, gingival graft procedures, NSAIDs.

CORRELATION OF INTERDENTAL AND INTERRADICULAR BONE LOSS – RADIOGRAPHIC ASSESSMENT
Christina Popova, Antoaneta Mlachkova, D. Emilov
Department of Periodontology, Faculty of Dental Medicine, Medical University - Sofia, Bulgaria
Background:
Furcation areas present some of the greatest challenges to the success of periodontal therapy. Higher mortality and compromised prognosis for molars with furcal involvement have been reported in several retrospective studies of tooth loss. Additionally, reduced efficacy of periodontal therapy has been consistently found in multirooted teeth with furcation involvement, regardless of the treatment modality employed (1). It is known that with progression of periodontal destruction and the involvement of furcal areas the severity of periodontitis increases and treatment is less effective because of limited access for mechanical control. Therefore it is of great importance that chronic periodontitis treatment happens before involving the furcal areas. The threshold of alveolar bone loss associated with progression of periodontal destruction and involvement of interradicular areas is not clearly defined in the literature.
This study was undertaken to investigate the connection between interradicular bone destruction and interdental bone loss in patient with chronic periodontitis.

REACTION OF 5 AND 6 YEAR OLD CHILDREN TO LOCAL ANESTHESIA DURING DENTAL TREATMENT
Kremena Nikolova-Varlinkova, R. Kabaktchieva
Departement of Pediatric Dentistry, Faculty of Dental Medicine, Medical University – Sofia, Bulgaria
SUMMARY:
One of the most delicate and difficult procedure in pediatric dental treatment is the administration of local injection anesthesia. There are literary data showing that dental anxiety in children might be due to maternal anxiety, family influences, personality and psychological development of the children, and previous painful medical and dental experience.
The aim of this study was to compare children’s reaction to two techniques of local anesthesia administration - the one in which the dentist shows the needle prior to local anesthetic administration to the child and the other in which the dentist does not show the needle. It aims also at investigating if there is a connection between mother’s and child’s attitude to dental treatment and reaction of the child during anesthetic administration.
24 children aged 5 - 6 (12 girls and 12 boys) took place in this study. All participants needed local injection anesthesia as part of their treatment plan.
The collected data give us the reason to accept that there is no difference in the reaction of the children when we applied both different techniques for anesthesia (with or without showing the needle), because the results are identical. The study shows that local injection anesthesia can be successfully applied even at 5 and 6 years old children.
Key words: local anesthesia, dental treatment, children, fear.

CLINICAL AND GENETIC PECULIARITIES OF ISOLATED CLEFT PALATES
Vera Krumova
Departement of Orthodontics, Faculty of Dental Medicine, Medical University – Sofia, Bulgaria
SUMMARY:
The systematic investigations on genealogical data of children with clefts have revealed that there is clinical-genetic heterogeneity between cleft lips and/or palates (CL/P) and isolated cleft palates (CP). Isolated cleft palates are often a constituent part of syndromes. These clefts are most frequently found in Pierre Robin syndrome, as this syndrome is more typical for the girls than the boys. The following micro-symptoms were observed among the relatives of children with CP: bifid uvula (BU), palatal defect, submucous cleft, intrauterine healed harelip and cleft nose. The results have shown that 43.4% of the children of our sample manifested accompanying malformations and syndromes, which means that almost every second child with CP has additional congenital diseases. Among the examined relatives, 18.81% demonstrated various types of micro-symptoms. The genetic-mathematical data processing has revealed that only isolated CP demonstrated polygenic type of inheritance, while CP with accompanying malformations approached mostly the autosomal-dominant type of inheritance.
Key words: cleft palate, micro-symptoms, heredity, syndromes.

A STUDY ON CONGRUITY BETWEEN CLINICAL AND METRIC NORMS IN HUMAN DENTITION
Vera Krumova
Departement of Orthodontics, Faculty of Dental Medicine, Medical University – Sofia, Bulgaria
SUMMARY:
The relationship between dental-jaw system morphologic deviations and functional and esthetic disturbances, which may lead to aggravation of both general organism disorders and local periodontal pathologic alterations and early tooth loss, has focused the increasing attention of orthodontists. Our study aimed at examining the congruity between normal occlusion-articulation relations in permanent dentition of a patient sample defined as normal on prophylactic examinations and some metric methods used in orthodontics and anthropology, in order to establish if there were any metric changes in the dental arch, although the availability of normal occlusion relations. Our examinations in a sample of 60 subjects (aged between 14 and 30 years) found that for the norm of occlusion-articulation relations defined by Gerlach’s method, congruity was observed in 75% of the cases; for the norm of transversal relations defined by Korkhaus’ method, congruity was observed in 53.3% and for the norm of sagittal relations defined by Korkhaus’ method – in 71.2% of the cases.
The anthropometric examinations showed that concerning palatal indices, the examined palates were most frequently brachystaphylic (85.6%) and mesostaphylic (14.4%), in conformity with the previously observed results for the Bulgarian population (2).
Palatal expansion was predominant in males and palatal compression – in females, a fact that could be related to general individual development.
The results showed that from a clinical point of view, the differentiation of a "normal group" including children with normal occlusion-articulation relations, is justifiable, although the availability of some metric deviations.
Key words: norms, human dentition, anthropometric examinations.

ORAL HEALTH STATUS ASSESSMENT INDICATORS IN A CHILD DENTAL PATIENT
Kremena Nikolova-Varlinkova, R. Kabaktchieva
Departement of Pediatric Dentistry, Faculty of Dental Medicine, Medical University – Sofia, Bulgaria
SUMMARY:
In order to provide good quality dental care the pediatric dentist must assess each patient’s oral health, to foresee the risk of any possible changes in oral health and to take measures for its improvement. The oral health status should be assessed with appropriate indicators, as well as to be recorded using a clinical form.
The aim of this study was to suggest basic indicators of oral health status assessment in a child dental patient and to create a clinical form for documenting the oral status examination information.
A documental research of the available Bulgarian and foreign literature presenting the variety of indicators of oral health assessment and clinic forms for recording the related information was carried out. An analysis of all contemporary documents of different dental organizations regulating oral health assessment in children was done.
As a result of the study the basic indicators of oral health status assessment in a child dental patient were identified. All the indicatiors and the related information were included in the newly created clinic form.
The current trend in pediatric dental medicine is the unification of oral health status basic indicators. It is possible to change the indicators in order to update and compare them.
Key words: oral health status, indicators, clinical forms.

POSSIBILITIES FOR CORRECTING THE CARIESOGENIC POTENTIAL OF CARBOHIDRATE FOODS AND DRINKS TROUGH THE CONSUMPTION OF KERNELS
Milena Peneva
Departement of Children’s dental medicine, Faculty of Dental Medicine, Medical University - Sofia, Bulgaria
SUMMARY:
Measuring the plaque рН after the intake of different foods is a method of determining the cariosogeneity of a given food as well as for determining the protective potential of other foods. In previous studies we have proven the protective effect of dairy products. It is assumed that kernels have a protective quality with regard to the enamel too. Hence the aim of the study - to check the possibilities of the kernels to correct the plaque рН after an intake of different carbohydrate foods.
For each experiment a group of 10 children was formed. For measuring the plaque рН the method of plaque sample was used. For each product tested the curve of Stephan was built.
On the one hand, the kernel’s potential to increase the plaque рН decreases the time during which the enamel demineralises. On the other hand, the increase of the plaque рН makes it possible for the kernels to evince other positive qualities concerning the enamel. When the рН is increased the presence of calcium and phosphopeptides becomes an important factor since the remineralisation of the enamel is enhanced. A simultaneous effect is the antimicrobic attack against S. Mutans. The positive effect from the comsumption of kernels makes it possible for us to recommend kernels as a food protecting against the development of caries.

Milena Peneva
Departement of Children’s dental medicine, Faculty of Dental Medicine, Medical University - Sofia, Bulgaria
SUMMARY:
Dental fluorosis is the result of chronic endogenic intake of fluorides in amounts exceeding the optimal daily dose of 1 ppm.
In our country different mineral waters with high content of fluorine are on the market. As a result in numerous regions and settlements the cases of fluorosis with different degrees of seriousness have become more frequent in recent years.
The aim of this study is to test the application of hydrochloric acid-pumice abrasion for the removal of fluorosis stains and remineralisation of the enamel.
At the Department of Children’s dental medicine to the Medical university - Sofia 18 children aged 4 - 15 were treated for different degrees of fluorosis. The method of microabrasion was applied employing the ready-made product "Opalustre", and the remineralisation - employing Tooth Mouse. In the case of all chidren individual prophylactic programs were implemented, including motivation and training in oral hygiene, a food regimen and rules of carbohydrate intake, avoiding fluorine water, control of the local fluorine toothpastes used, etc.
The treatment with microabrasion conducted and the subsequent remineralisation give very good results. These results include a recovery of the aesthetics of the teeth, remineralisation of the enamel, full disappearance of the enamel erosions and a dimimution of the dentine erosions.

ACTIVITY OF THE CARIES PROCESS
Milena Peneva
Departement of Children’s dental medicine, Faculty of Dental Medicine, Medical University - Sofia, Bulgaria
SUMMARY:
The contemporary non-operative approach in cariesology requires a new type of diagnosing. It is an approach that embraces the early detection of the caries lesions and the early specification of the character of the caries process at the moment of examination. Such an approach allows the early diagnosing of the active caries process as well as the early modelling of the process.
The broadly used in epidemiological studies DMF index provides no information for the activity of the caries process, for the quantity of the reversible lesions as well as for what non-operative treatment should be applied. The index has been created as early as 1930 when the operative treatment was dominant.
On the basis of the epidemiological study of a 1000 children aged 6-15 as well as with the help of a methodology embracing strict criteris for the separate diagnostic bands and for the activity of the caries lesions, an IA index was created showing the strength of the current caries process and supplementing the information obtained by means of the DMFT and DMFS indexes. The index could be very helpful in obtaining information within any epidemiological study and would facilitate the choise adequate therapeutic approach in accordance with the caries process observed.

Departement of Children’s dental medicine, Faculty of Dental Medicine, Medical University - Sofia, Bulgaria
SUMMARY:
The DMFT (S) index, created at a time when caries was thought to be an irreversible condition of the tooth structures, proves now to be insufficiently informative under the present situation. The non-operative preventive therapeutic approach is highly regarded now, which is an approach requiring additional information on the reversible carious pathology so that an adequate treatment could be applied.
The epidemiological examination of a 1000 children aged 6 - 15 has been conducted in Sofia and Rousse – two big Bulgarian cities in which no public prophylactic programme has been carried out. On the basis of predetermined diagnostic criteria for the determination of the reversible phases in the development of the dental caries and by accepting an early diagnostic thershold, an IR reversibility index was created. This index is very helpful in supplementing the information obtained by means of the DMFT and DMFS indexes, allowing us to determine the correlation between the reversible and irreversible lesions within the DMF index and making possible adequate therapeutic decision-making. The IR reversibility index is there for the sake of preventive approach in modern cariesology and can successfully be used in epidemiological studies.

Departement of Children’s dental medicine, Faculty of Dental Medicine, *Department of Biochemistry, Faculty of Medicine, Medical University - Sofia, Bulgaria
< SUMMARY:
The pulpo-dentinal complex has protective qualities safeguarding the dental pulp from progressive inflammations and traumatic lesions. This effect is achieved through the formation of a dentine-like structure made-up of cells capable of additionally differentiating. It is supposed that these are multipotent stem cells. The isolation and proving the existence of such cells is of crucial importance for regenerative medicine.
It is the aim of this project to isolate primary structures of mesenchymal stem cells from the pulp of temporary teeth.
The isolation of primary cells from the pulp of temporary teeth to be physiologically replaced was carried out. Immuno-fluorescence, analysis of the cell proliferation and a vitality test (MTT) were conducted too.
The project accomplished succeeded in isolating stem cell from the pulp of exfoliated temporary teeth. Such cells when in norm manifest no proliferation capacit.

It is the aim of this project to prove the presence of the primary structures of mesenchymal stem cells from the pulp of temporary teeth and characterising as well as determining the impact of growth factors TGF-β2 and BMP-2 on the model system studied.
Immuno-fluorescence, analysis of the cell proliferation and a vitality test (MTT) were conducted. The impact of BMP-2 (Bone Morphogenic Protein-2) and TGF-β2 (Transforming Growth Factor-β2) on the isolated and cultivated colonies of stem cells was determined.
The project accomplished succeeded in isolating stem cell from the pulp of exfoliated temporary teeth. Such cells when in norm manifest no proliferation capacity. Stimulated with the help of growth factors, the cells come to manifest a clear potential for proliferation, though, and later become capable of multipotent differentiation.
