The role of autophagy in protecting periodontium integrity, and lipopolysaccharide-induced osteoclast differentiation
The periodontium is a dynamic tissue that undergoes constant remodeling to maintain its structure and function. There is much evidence in the literature that autophagy can be activated by both mechanical stretching and inflammation, however the mechanisms involved are highly context dependent. …

Changes of the Marginal Periodontium as a Result of Labial Tooth Movement in Monkeys
<p>Orthodontic tooth movement was performed on five monkeys (Macaca nemistrina). Oral health was established and exploratory surgery was performed to assess the level of the connective tissue attachment and marginal bone. Measurements of the gingival margin and mucogingival junction were taken and …

Clinical and radiographic observation of the periodontium in patients undergoing orthodontic therapy: first twenty-seven months
… and qualitative changes occurring in the periodontium during and following orthodontic therapy. The patients were examined for the first 9 month period by Dr. Stuart Sears and Dr. Sergio Tejedor-Leon. Relocation of two families reduced the number of patients to twenty which were examined …

Clinical and Morphological Features of Periodontium in the Aesthetic Zone of the Maxilla /// Клинико-морфологични особености на пародонта в естетичния участък на горната челюст
… The clinical and morphological features of the periodontium, such as interdental papillary height, periodontal biotype, tooth form, smile line, gingival recessions, height and thickness of alveolar bone, are described as key factors for successful aesthetic outcome in periodontal, implant and …

Periodontal aspects of Endodontics
… other irritants may migrate from the pulp to the periodontium and vice versa through physiological communication pathways such as apical foramen, dentinal tubules and lateral canals. Such exchange of pathogens often contributes into the development of the endo-periodontal lesions. Despite the …

Zusammenhang zwischen methanogenen Archaea und sulfatreduzierenden Mikroorganismen bei Parodontitis
… reaction can lead to the deterioration of the periodontium and lately to the loss of the tooth itself. Initial examinations proved that methan-producing (methanogenic) archaea and sulfate-reducing micro-organisms are present in periodontal pockets. Up to now these both groups of organisms have …

Comparison of Treatment Methods for Chronic Periapical Inflammatory Diseases // Сравняване на методи за лечение на хронични периапикални възпалителни заболявания
… filling of the root canal to isolate the apical periodontium from contact with saliva in the oral cavity. The removal of the etiological factor is associated with mechanical and chemical treatment of the root canal. Since most endodontic problems are of microbial origin, their removal is …

V- Shaped Defects – Epidemiology, Clinical Picture and Obturation Opportunities // Клиновидни дефекти – епидемиология, клинична картина и възможности за обтуриране
… front teeth. Their deepening leads to pulp and periodontium disease. The present work deals with epidemiology, the clinical picture and the possibilities of v-shaped defects. The leading role of local factors - tooth brushing frequency and hardness of the toothbrush in the aetiology of wedge …

EVALUATION OF LONG-TERM EFFICACY OF FORCED ERUPTED TEETH FOR RESTORATIVE PURPOSES – A CLINICAL RETROSPECTIVE STUDY
… In cases with pristine adjacent teeth and intact periodontium or a hopeless tooth that demands vertical alveolar bone augmentation, forced eruption is a conservative treatment approach. Current evidence in the literature is lacking in regard to the long-term (> 1 year) prognosis of forced erupted …

Investigation of the application of polylactic acid-calcium phosphate composite materials as novel periodontal barrier membranes
… restoring the aesthetics and function of the periodontium. Guided tissue regeneration (GTR) is one technique that is used clinically to promote tissue regeneration. The technique employs a membrane to create space in the appropriate surgical site to produce periodontal regeneration. However …

The study of cell surface components on Porphyromonas gingivalis
… major role in mixed bacterial infections of the periodontium. The objective of the study was to clone genes encoding, and characterize cell surface components of P. gingivalis as potential virulence factors of this organism. AP. gingivalis ATCC 33277 genomic library was generated. Clones were …

New Attachment of Connective Tissues to Human Teeth Involved in Chronic Periodontal Disease : A Histologic Study
<p>Reconstruction of the periodontium destroyed by periodontal disease may be considered an ultimate goal of reconstructive periodontal therapy. To date, there has been no concrete evidence demonstrating this phenomenon in humans. Garrett (1978) has shown that citric acid, after application to root …

Die parodontalen Verhältnisse verlagerter Eckzähne und Frontzähne im Oberkiefer nach chirurgisch-kieferorthopädischer Therapie - eine retrospektive Untersuchung
Die Einstellung retinierter und verlagerter Zähne im Front- und Eckzahngebiet ist eine häufige Behandlungsaufgabe. Sie stellt isoliert oder im Rahmen einer komplexen kieferorthopädischen Behandlung teilweise schwierige Behandlungsschritte dar und kann häufig nur interdisziplinär gelöst werden. Ziel …
