The aim of the study is to evaluate the usefulness of cone-beam computed tomography (CBCT) in the assessment of the relationship between the cemento-enamel junction (CEJ) and bone crest of the anterior mandibular cortex. The study population comprised 39 males and 61 females, aged 18–71. A GENDEX GXCB-500 machine, i-CAT Vision and CorelDraw 9 software were used. The distances between the CEJ and bone crest at buccal and lingual sides of six anterior mandibular teeth were measured. Descriptive statistical methods, Student’s t-test and ANOVA were used. The mean distance between the bone crest and CEJ was 2.32 mm ± 0.78 mm at the buccal and 2.52 mm ± 0.85 mm at the lingual side. It was found that in males aged over 50 years, the mean distance at the buccal side was 2.84 mm ± 0.79 mm and was significantly higher than in males aged 49 and less – 2.08 mm ± 0.41 mm. The mean distance at the lingual side was 3.28 mm ± 1.08 mm and was significantly lower in the age group of 49 years and less – 2.10 mm ± 0.41 mm. CBCT allows determining the distance between the CEJ and crestal bone margin at buccal and lingual sides. The data provide crucial information for planning orthodontic treatment, implant placement and periodontal therapy.

Lipoma is a benign tumour originating from mature adipose tissue. It can occur in any place in the body where adipose tissue is located. Intraosseous lipoma is a very rare bone tumour. The authors present an infrequent case involving intraosseous lipoma of the mandible in a 32-year old man and provide a review of case studies documented earlier in the literature.

McCune Albright syndrome (MCA) is a rare complication of genetic origin. The authors present a case study of a patient with MCA diagnosed with multifocal fibrous dysplasia in his limb and craniofacial bones. The symptoms of the disease in the patient’s facial and oral tissue and the treatment administered have been described.

Transmigration is a tooth pathology in which the migrating tooth bud passes the median plane. Methods: This study is a presentation of the diagnostic and therapeutic outcomes in the cases of 4 stomach teeth transmigrations diagnosed in 3 patients with mandibular retrognathia which was a complication after osteitis in the postnatal period and infancy. Results: Extending imaging diagnostics to include CT, most preferably CBCT, makes it possible to precisely evaluate a transmigrated canine’s position and to plan a course of treatment. Conclusions: Planning of the treatment of teeth in transmigration in patients with temporomandibular ankylosis should be done by a team consisting of an orthodontist and a surgeon.

Autotransplantation is a well-known method used in oral surgery. However, risk of failure, most commonly resulting from root resorption of the transplanted tooth or ankylosis, is quite high. Piezosurgery with specific device tip vibration frequencies enables selective tissue cutting, and therefore, tooth buds or teeth can easily be removed from bones with little injury to periodontal fibers or bud follicles.

The aim of the study was to evaluate 10-years of clinical material referring to the rare dental abnormality of double teeth. The study material consisted of case records, operation-books and radiographic or photographic documentation on patients treated in the Department of Oral Surgery, Silesian Medical University, Katowice, from the 1st of June 2000 to the 31st of May 2010. The following features were considered important: age and sex, the reason why the patient reported for treatment, general state of health, the time of recognition and type of double teeth, location of double teeth, complaints and disturbances connected with double teeth, types of radiographs, the radiographic and macroscopic appearance of double teeth and treatment method. Diagnoses were as follows: eight conrescent teeth, two fused teeth, two geminated teeth and one invaginated tooth. The anomaly of a deciduous tooth was referred to in one case only. Double teeth were most often seen in the region of maxillary incisors and molars but rarely in the mandible. The region of incisors was affected chiefly in children and the region of molars in adults. Double incisors are usually recognized prior to treatment whereas double molars as late as during their extraction. In many cases, neither intraoral radiographs nor pantomographs help to confirm double teeth or provide sufficient information to plan the treatment. In such a situation, CT or CBCT should be used in addition to imaging diagnostics. Double teeth among incisors are usually accompanied by occlusal disorders. Therefore the therapeutic management is conducted by a team, including orthodontists. [ABSTRACT FROM AUTHOR]

Preserving natural and healthy dentition till the end of life is strongly connected with regular control visits at the dentist's surgery and following therapeutic procedures that may be found necessary. Today's society develops an awareness of the necessity to preserve good health of the oral cavity. Therefore, dentists attempt to provide medical care to the patients of all ages, including menopausal women. Women at the perimenopausal or post-menopausal age often experience a decrease in estrogenic hormone concentration due to discontinued endocrinological activity of the ovaries. This leads to a number of systemic implications, including the negative effect on salivary glands and oral mucosa. It is important to keep in mind that such patients may suffer from oral diseases specific to their age. This paper presents most common oral diseases that occur in women at the menopausal or perimenopausal age. While the systemic aspects of menopause are well documented, the awareness of oral discomfort as a part of menopausal complaints is still low. The authors present the current state of knowledge on how deficiency or supplementation of estrogens can affect salivary glands and oral mucosa in perimenopausal and post-menopausal women. Particular attention is paid to symptoms resulting from abnormal lubrication of oral mucosa or burning mouth syndrome, the latter quite common among menopausal women. Also, the authors describe some therapeutic methods that may be used to treat the diseases. [ABSTRACT FROM AUTHOR]

Mucoceles are common pathological lesions of the oral cavity, usually measuring up to 10 mm. The authors describe a case of deeply located buccal mucocele measuring 35 mm in diameter. The lesion was caused by facial injury in a 54-year old man. The lesion persisted for approximately 2.5 years and was difficult to diagnose because of its unusual size and atypical clinical symptoms. Preoperative ultrasonography excluded a tumor, and this was confirmed by histopathological examination. However, oncological alertness was considered necessary on account of ulcerated mucosa next to the lesion. The mucocele was removed through surgical excision, using a scalpel and tissue scissors. No recurrence was observed in 2.5 postoperative years. It is stressed that histopathological examinations help to differentiate mucoceles from other disease processes. [ABSTRACT FROM AUTHOR]

Background: IL-1 is the main regulator of inflammatory reactions. This cytokine also plays an important role in bone tissue remodeling processes. The IL-1α-coding gene and the IL-1β-coding gene are located on the long arm of chromosome 2. These genes contain polymorphic sites. Polymorphic modifications in IL-1-coding genes determine the level of IL-1 release, which can affect bone tissue regeneration., Objectives: The objective of the present study was to assess the correlation between IL-1B-511 genetic polymorphism and the regeneration of the alveolar ridge bone., Material and Methods: The study was carried out at the Department of Oral Surgery in Bytom, Poland, which is part of the Silesian Medical University of Katowice. The study population comprised 92 patients with mandibular or maxillary alveolar bone defects which had developed following the surgical removal of tooth roots or the enucleation of impacted teeth or cysts. Genetic material was obtained from the epithelial cells of the inner buccal surface. The IL-1B-511 genotype was determined in each patient by means of the phenol-chloroform technique, in order to enable DNA isolation, as well as by the PCR-RFLP method. Once this had been achieved the patients could be classified into 3 groups according to the following genotypes: IL-1B-511 1/1, IL-1B-511 1/2 and IL-1B-511 2/2. Bone regeneration was assessed radiographically using Digora 2.5 software. A comparison was made over a 6-month follow-up period of post-operative bone loss regeneration observed in patients with different types of the IL-1B-511 gene (alleles 1/1, 1/2, 2/2)., Results: A careful analysis of the X-ray images showed that the average increase in the optical density of post-operative bone defects was statistically lower in patients with the IL-1B-511 2/2 genotype than in those possessing the IL-1B-511 1/1 or IL-1B-511 1/2 genotypes. The results indicate that alveolar bone regeneration proceeds more slowly in patients with the IL-1B-511 2/2 genotype compared to those with alleles 1/1 and 1/2.

This study assessed the viability of bone and soft tissue healing at the wound extraction site, when the wound was both covered and not covered with a mucoperiosteal flap. In total, 40 patients were enrolled in the clinical study and were randomly allocated to each treatment cohort group.

Neurilemmoma is a benign neoplasm of neuroectodermal origin. The authors present a rare case of this lesion localized in the oral cavity. Clinical symptoms, histologic structure of the tumor, methods of treatment and differential diagnosis are described.

Trigeminal neuralgia (TN) is a syndrome affecting usually one half of the face and consisting of severe pains within one or more branches of the nerve. One of the methods for conservative treatment is using anesthetic drugs in the form of perineural sensory branch blockades n. V. If these are found ineffective, alcoholic blockades are used in some cases although complications like necrosis, tissue fibrosis or risk of developing a neuroma may occur. The paper describes a case of complication after alcoholic blockade into left mental nerve, namely oral tissue necrosis.

Oral surgery procedures are often the cause of painful sensations because of their tissue invasiveness. To avoid these sensations a wide use of nonsteroid antiinflammatory drugs is usually accepted. Because of plenty side effects of these drugs alternative antipain agents are desired. The goal of this study was to assess antipain effect of laser stimulation and alternating magnetic field in oral surgery procedures. Pain sensations in patients during: local anesthetics application, surgical procedure and after it were assessed according to VAS scale. Level of stomatological fear was assessed with the use of Corah's scale. Achieved results were analyzed statistically. Conclusion of this analysis is that laser stimulation and alternating magnetic field applied directly before oral surgery procedure are effective antipain agents that decrease intra and postoperative sensations. It was observed that patients with high level of stomatological fear had more pain sensations but even in this group laser and magnetic stimulation significantly lowered these complaints.
