Long-standing oral ulcers: proposal for a new `S-C-D classification system’
2008
Persistent oral ulcers and erosions can be the final common manifestation, sometimes clinically indistinguishable, of a diverse spectrum of conditions ranging from traumatic lesions, infectious diseases, systemic and local immune-mediated lesions up to neoplasms. The process of making correct diagnosis for persistent oral ulcers still represents a challenge to clinicians. Major diagnostic criteria should include the clinical appearance of both ulcer and surrounding non-ulcerated mucosa, together with the evaluation of associated signs and symptoms, such as: number (single or multiple), shape, severity of the ulcer(s), conditions of remaining mucosa (white, red or with vesiculo-bullous lesio…
Antibiotic susceptibility of cocultures in polymicrobial infections such as peri-implantitis or periodontitis: an in vitro model.
2011
Although polymicrobial infections, such as peri-implantitis or periodontitis, were postulated in the literature to be caused by synergistic effects of bacteria, these effects remain unclear looking at antibiotic susceptibility. The aim of this study is to compare the antibiotic susceptibilities of pure cultures and definite cocultures.Laboratory strains of Aggregatibacter actinomycetemcomitans (Aa) (previously Actinobacillus actinomycetemcomitans), Capnocytophaga ochracea (Co), and Parvimonas micra (Pm) (previously Peptostreptococcus micros) were cultivated under anaerobic conditions, and their susceptibilities to 10 antibiotics (benzylpenicillin G, ampicillin, amoxicillin, ampicillin/sulba…
Associations between single-nucleotide polymorphisms of the VEGF gene and long-term prognosis of oral squamous cell carcinoma.
2012
Department of Otorhinolaryngology, Johannes Gutenberg-University, Mainz, GermanyINTRODUCTION: Functional polymorphisms (SNPs) ofthe vascular endothelial growth factor (VEGF) are asso-ciated with the incidence of oral squamous cell carcinoma(OSCC). An impact of VEGF-SNPs on prognosis of OSCCpatients seems possible. Therefore, correlations betweenprognostic parameters of OSCC patients and five VEGF-SNPs were determined.MATERIALS AND METHODS: In a retrospective long-term study, in 113 OSCC patients that underwentcurative resections, five VEGF-SNPs ( 1154 G/A,+405 G/C, +936 C/T, 2578 C/A, and 460 C/T) wereanalyzed. Associations between SNPs and prognosis(incidence of local recurrent disease, seco…
Not a current fashion, but a truth since 1884
2011
We thank Kucharz [1] for the valuable historical comment to our review focusing on the role of oral infection on systemic diseases [2]. The majority of scientists today write and read the English language whereas articles in Polish and German are scarcely known outside of Poland and Germany, respectively. For these reasons, the contribution of Kaczorowsky [3] is commonly forgotten in medical literature, but the letter of Kurchaz properly acknowledges this pioneer researcher in the periodontal medicine. We also thank Blum [4] for adding his results [5,6] to our review article. As the number of references citable is limited, we did not cite the articles written by Blum et al. [5,6], but we re…
Assessment of sleep disturbance in oral lichen planus and validation of PSQI: A case-control multicenter study from the SIPMO (Italian Society of Ora…
2021
Background: The wellbeing of oral lichen planus patients (OLPs) may be strongly influenced by a poor quality of sleep (QoS) and psychological impairment. The aims were to analyze the prevalence of sleep disturbance, anxiety, and depression in OLPs and to validate the Pittsburgh Sleep Quality Index (PSQI) in OLPs. Methods: Three hundred keratotic OLPs (K-OLPs), 300 with predominant non-keratotic OLP (nK-OLPs), and 300 controls were recruited in 15 Italian universities. The PSQI, Epworth Sleepiness Scale (ESS), Hamilton Rating Scales for Depression and Anxiety (HAM-D and HAM-A), Numeric Rating Scale (NRS), and Total Pain Rating Index (T-PRI) were administered. Results: Oral lichen planus pati…
Determination of the facial/oral alveolar crest using RF-echograms. An in vitro study on the periodontium of pigs.
1989
Abstract This study is a part of a research project in which we have been investigating the use of the ultrasonic pulse echo technique as a means of determining in vivo the facial/oral alveolar crest precisely and routinely. Here, RF-echograms are presented, showing the facial/oral periodontium of pigs. These echograms have been produced using a focussed 20 MHz transducer and a special design of an ultrasonic measuring and analysis system. In one series of measurements on macerated periodontia of pigs we found out that RF-echograms characteristic of a particular level of the facial/oral pericrestal aspect can be achieved. Based upon these results, we succeeded in determining exactly the hei…
Ultrasonic B-scans of the facial/oral periodontium in pigs.
1989
In vitro ultrasonic scans of the oral/facial periodontium of pigs were obtained using a special experimental design and with the help of a newly developed ultrasonic measuring and analysis system. These two-dimensional images distinguish themselves from the one-dimensional RF-echograms and A-scans in that they enable the viewer to have a quick overview of the relationship between different interfaces in a scanned sector. A selection of ultrasonic B-scans proves that the scanned tissues such as gingiva, bone, periodontal ligament, tooth surface and even structures of the inner part of the tooth may be clearly imaged and distinctly differentiated. Furthermore, we demonstrate with manipulation…
Diagnostic Pathways and Clinical Significance of Desquamative Gingivitis
2008
The term desquamative gingivitis (DG) refers to a clinical manifestation that can be caused by several disorders. Many of them are immunologically mediated; in addition to the oral cavity, they can affect extraoral mucocutaneous sites, e.g., larynx, conjunctiva, esophagus, nasal and genital mucosa, and the skin. The degree of oral, periodontal, and systemic involvement determines the overall morbidity and, sometimes, the mortality of these disorders. We comprehensively review disorders commonly associated with DG and highlight diagnostic pathways, guidelines for differential diagnosis, and oral, periodontal, and systemic implications. More rare conditions are reviewed as well. Mucous membra…
Histologic Evaluation of Human Intrabony Defects Following Non-Surgical Periodontal Therapy With and Without Application of an Enamel Matrix Protein …
2003
Background: Surgical periodontal treatment with enamel matrix protein derivative (EMD) has been shown to promote periodontal regeneration. However, it is not known whether nonsurgical periodontal therapy with additional subgingival application of EMD may also enhance periodontal regeneration. The purpose of this study was to clinically and histologically evaluate healing of human intrabony defects following non-surgical periodontal treatment with and without application of EMD. Methods: Sixteen patients, each of whom displayed one advanced intrabony defect around teeth or roots scheduled for extraction, were included in the study. The defects were treated as follows: 1) scaling and root pla…
Predictors of tooth loss due to periodontal disease in patients following long‐term periodontal maintenance
2015
The pioneering attempt to characterize the response to periodontal treatment of patients undergoing periodontal maintenance (PM) (Wasserman & Hirschfeld 1988) was soon followed by the first studies on periodontal prognosis (McGuire 1991, McGuire & Nunn 1996a,b, McLeod et al. 1998). Two main conclusions were drawn, which remain generally accepted: establishing a periodontal prognosis is the basis of any treatment plan, and actual knowledge of the predictors of tooth loss (TL) is very limited. An extensive review on the subject noted the heterogeneity of the studies and the scarce information that could be drawn from them (Chambrone et al. 2010). Several statistical models analysing the predi…
