Contemporary views on the treatment of recurrent aphthous stomatitis – a literature review
Get PDFRecurrent aphthous stomatitis (RAS) is a common disease of the oral mucosa. This problem affects about 5–20% of the population. The etiopathogenesis of the disease is multifactorial and still not fully understood. The related changes cause pain that hinders food intake, speech and swallowing. The treatment is mainly symptomatic. Its aim is to relieve pain and accelerate healing. It can be divided into local and systemic. The paper describes contemporary views on RAS treatment depending on the severity of the symptoms. Local terapeutic agents available in Polish pharmacies which can be applied in treating the diseases are discussed. Their composition and dosage are analyzed. The topic of systemic and laser therapy is also presented
Osteoperception in patients with implant-supported dental prostheses – a literature review
Get PDFThe aim of this paper is a review of the literature on the perception of mechanical stimuli and perceptive transmission in patients after restorations of the masticatory organ with implant-supported dental prostheses. The difference between the perception of external stimuli in the oral cavity with natural teeth and that which occurs in the presence of intraosseous implants results from different neuronal structures and the manner of transmitting those stimuli. The reactions of patients with dental implants to mechanical stimuli and their effect on the motor activity of the stomatognathic system are discussed. Osteoperception is an important yet not completely explained form of response to the loading and movements of the mandible linked to type I, II and III receptors, which continues to interest researchers and practitioners. Sensory and motor control in patients with intraosseous implants enables the natural function of the stomatognathic system due to its physiological and psychophysical intergration with the body
The etiology of open bite
Get PDFOpen bite is a malocclusion in which there is no contact between upper and lower anterior or posterior teeth or between all the teeth at the same time. The complexity of this malocclusion is caused by a combination of skeletal, dentoalveolar and functional factors. The aim of this study was to review both Polish and international literature concerning the above mentioned factors. The etiology of open bite is a combination of genetic and environmental factors. Usually permanent habits such as thumb and dummy sucking and nose obturation have an unfavourable influence on the development of the dentoalveolar complex and disturb physiological tooth eruption. Some important factors of skeletal open bite malocclusions are a genetic component, traumas, condylar degeneration and masticatory muscle malfunctions. Accurate diagnosis of the causes of open bite is a very important criterion in the correct planning and choice of treatment
Extensive orbital damage as a result of maxillary sinus surgery – a case report and literature review
Get PDFClassic and FESS (Functional Endoscopic Sinus Surgery) surgery of the sinuses are connected with the possibility of surgical complications involving the orbital structures and the eyeball. Most frequently these involve bleeding from the vessels of the orbit and the nasal cavity. A rare and certainly the most serious complication is blindness resulting from damage to the optic nerve. This paper presents a case of postoperative blindness as a result of maxillary sinus surgery complicated by damage to the orbital floor and its inadequate reconstruction
Problems of conservative treatment in geriatric patients
Get PDFToday’s developments in medicine as well as widely practiced preventative methods contribute to the fact that patients in advanced age constitute a growing number of people requiring dental assistance. Wishing to retain their natural set of teeth, they require complicated dental treatment. In this research, selected, difficult clinical cases in elderly patients are presented and also a suggestion of preventive and therapeutic methods as a preparation for prosthetic rehabilitation of the stomatognathic system. Taking into consideration the following clinical cases, patients were divided into several groups: 1) numerous and extensive non-carious lesions; 2) pathological attrition of teeth combined with occlusion malfunction; 3) pathological attrition complicated by changes in periodontal tissue; 4) non-carious lesions and root caries co-existing with prosthetic crowns and bridges. After analysis of the presented clinical cases it might be claimed that the elderly patients, due to complex changes in the dental system, constitute a challenge for the dentist and the preparation of the treatment plan must be depend not only on clinical indications but also on their health and financial circumstances
Precision attachments – a literature review
Get PDFPrecision attachments such as dental clips improve the retention of removable partial dentures, chewing efficiency and also the correct appearance of the patient. This article describes the different kinds of precision attachments and the possibility of using them in dental practice
Oral hygiene levels and oral cavity pro-health behaviours of patients with cardiovascular diseases
Get PDFIntroduction. Studies in the relationships between periodontal diseases and cardiovascular diseases are one of the main research areas in contemporary periodontology. The data published in recent years indicate periodontitis as one of the potential risk factors for coronary heart disease (CHD) and myocardial infarction (MI). Thus the population with cardiovascular diseases is recommended as a target for dental prophylaxis and pro-health educational programmes. Aim of the study. The aim of this study was the assessment of oral hygiene levels and dental pro-health behaviours among patients with CHD and MI. Material and methods. The study encompassed 86 individuals with MI (group 1), and 84 persons with stable CHD (group 2). The control group comprised 50 persons without cardiovascular diseases. Clinical examinations of oral hygiene level using API, gingivitis level using mSBI, and an individual questionnaire regarding dental pro-health behaviours and oral hygiene maintenance methods were performed. Results. Low oral hygiene levels were observed in the examined groups (mean API value: 68.72%, 68.44%, and 60% respectively). Data from the questionnaires revealed a lack of proper periodontal prophylaxis. Gum bleeding was not considered as a pathological symptom, about 60% of patients never participated in oral hygiene training, and the frequency of dental control check-ups and professional hygiene procedures was too low. Only a few percent of patients cleaned interdental spaces. Conclusions. The results obtained indicate a low level of dental pro-health behaviours and could support recommendations regarding the necessity of educational, prophylactic and treatment programmes for patients with CHD / MI – performed by dentists / periodontologists and cardiologists togethe
Bisphosphonate-related osteonecrosis of the jaw. A review of the literature
Get PDFOsteonecrosis generally occurs due to cardiac insufficiency which leads to an interruption of the nutrient supply. Recently, osteonecrosis affecting only the jaw bones has been described as a unique complication connected to bisphosphonate therapy: Bisphosphonate-Related Osteonecrosis of the Jaw (BRONJ). There are still a lot of unknown factors involved in the management and treatment of patients taking bisphosphonates. Since 2003 reports of BRONJ were associated with intravenous and oral BP therapy for Paget’s disease and osteoporosis. BRONJ can occur spontaneously, due to dental disease or as a consequence of dental therapy. Old age, periodontitis, chronic corticosteroid therapy, prolonged use of bisphosphonates, smoking, and diabetes mellitus all may increase the risk of osteonecrosis. Expert panel recommendations for clinical decision making should also be balanced with the practitioner’s professional judgement and the individual patient’s needs
The influence of physical effort during a progressive test on calcium concentration in resting mixed saliva
Get PDFIntroduction. Calcium is the most common macro-element in the human body. In addition to its building function it is also involved in a number of other processes, such as homeostasis, contractility of smooth and skeletal muscles or the regulation of blood pH and enzymes. Physical exercise causes a dynamic change in the deposition of calcium in bone. Calcium is present in the oral cavity, the hard tissues of teeth, dental plaque, gingival fluid and saliva. Aim of the study. An assessment of the influence of physical exercise during a progressive test with a measurable work value on the concentration of calcium in resting mixed saliva in athletes. A comparison of calcium concentration in the saliva of athletes before and after exercise with the concentration of calcium in the saliva of people not practising sport. Material and Methods. The study examined 117 men aged 18–26 years (av. 21.2), including 74 athletes (cyclists and students of Physical Education in Wroclaw before and after a progressive exercise test) and 43 men who are not professional sportsmen and who have not performed a progressive test. A marked resting rate of secretion of mixed saliva supernatant was used to determine the calcium concentration of resting mixed saliva. Photometric analysis was performed, using the diagnostic kit Alpha Diagnostic at a wavelength of 630 nm. In statistical analysis the Student’s t-test and Pearson's correlation analysis were used with a P value < 0.05. Results. The mean concentration of calcium before exercise was 3.65 ± 2.51 mg/dl and after exercise 6.20 ± 11.85 mg/dl (difference not significant). The concentration of calcium in the control group had a value of 3.84 ± 2.73 mg/dl and was also not significantly different compared to the athletes. There was a significant decrease in salivary flow rate caused by physical effort from approximately 0.33 ml/min to 0.29 ml/min (p < 0.01). The correlation analysis showed no significant interdependence between the time and the work performed and the concentration of calcium. Conclusions. 1. Exercise induces a slight increase in the calcium concentration in saliva. 2. Physical activity decreases salivary flow rate
