An analysis of bone changes in the jaws caused by primary hyperparathyroidism (PHPT) was performed based on the research and our own studies. Presented are the modern principles for the diagnosis of PHPT in patients undergoing treatment in maxillofacial clinics with recurrent epulids and jaw cysts. Variously expressed tumor jaw lesions were observed in 23 of 751 patients. 19 of them have the lower jaw, and 4 have the upper jaw tumors. Tumorous masses in 15 patients were caused by parathyroid adenoma, in 7 – by hyperplasia, in 1 – by cancer. The only clinical manifestation of hyperparathyroidism in 5 patients was a tumor-like mass of the upper jaw, in 1 – the lower one. Changes in the bone structure of jaws were found in PHPT patients who underwent orthopantomography, x-ray or computed tomography of the skull. In 26 of them, grainy and coarse-grained bone reconstruction was determined, in 9 – diffuse rarefaction of facial bones, in 10 – focal osteoclasia, in 21 – resorption of the closing plates of the dental alveoli, in 19 – subperiosteal resorption of the cortical layer of lower jaw. It was found that almost impossible to differentiate osteoblastoclastoma and hyperparathyroid osteodystrophy on a pathomorphological basis. In case of detected PHPT, first of all, the operation is performed on the parathyroid glands, and then the treatment strategy for jaw epulids is determined.

Dens evaginatus (DE) is an odontogenic developmental abnormality that can be defined as a tubercle or bulge on the surface of a tooth, consisting of the outer layer of enamel, dentin, and possibly pulp. Early diagnosis and treatment of dental evagination is important to prevent untimely endodontic treatment, occlusal trauma, aesthetics, and the development of fissure caries. This pathology of tooth development is usually found on the premolars of the lower jaw as an additional tubercle or bulge between the buccal and lingual tubercles. DE in the maxillary premolar has been reported rarely in the literature. We report one such rare case in the maxillary premolar.Material and methods. The article describes a clinical case of treating a patient with dental evagination. For observation, we used X-ray images made with CBCT, as well as a photo protocol of the stages of patient treatment.Conclusions. Since this pathology is rare, the description of this clinical case will help doctors better understand the approaches to dental treatment with such anomalies in the development of tooth tissues.

The objective of the study is to evaluate the condition of the alveolar part of the upper jaw and the part of the mandible according to X-ray studies in postmenopausal women before and after surgical treatment of the atrophy of jaw bone tissue using osteoplastic material and an ossein-hydroxyapatite compound. Materials and methods: There were observed 24 women in the postmenopausal period, aged from 51 to 58 years, with atrophy of the alveolar process of the upper jaw and the part of the lower jaw who were surgically treated. Results of the study. On the basis of the obtained results of the X-ray examination, we can assume that the developed by us technique of surgical treatment of atrophy of the alveolar process of the upper jaw and the part of the lower jaw by the use of bone material of animal origin in combination with the ossein-hydroxyapatite compound allows us to intensify bone tissue regeneration processes, which further will contribute to the increase of the volume of bone tissue. Conclusions. The use of modern X-ray methods, in particular orthopantomography and cone-beam computerized tomography in the diagnosis and surgical treatment of atrophy of the alveolar process of the upper jaw and the part of the lower jaw, are highly informative, and also provide the possibility of work with a roentgenographic image in a digital format that allows a more detailed assessment of the area of surgical intervention before and after the treatment.

Relevance. Detection of maxillofacial pathomorphological changes in children with connective tissue dysplasia (CTD) allows identifying the nature and severity of disorders, as well as it serves the basis for selecting the best treatment options in view of the pathogenetic features. The purpose is to improve the diagnosis of periodontal diseases in children with CTD based on x-ray morphometric indices of the lower jaw and peripheral skeleton ultrasound osteodensitometry.Materials and methods. 92 children with varying CTD severity, and 43 healthy children, underwent cone-beam computed tomogram examination with a further analysis of their X-ray morphometric (quantitative, qualitative) values and the lower jaw optical density indices. Besides, the status of the peripheral skeleton bone tissue was also determined through quantitative ultrasonic densitometry.Results. Quantitative X-ray morphometric indices in healthy children and children with CTD revealed strong positive correlation with the Z-criterion of osteodensitometry, offering an objective reflection of the bone tissue status in the peripheral skeleton.Conclusion. CTD progression in children correlates with the bone structure destruction intensity in the maxillofacial area, an increase in chronic productive inflammation, a decrease in the bone density, bone tissue fibrous transformation, a decrease in the thickness of cortical, and fiber-dissociation in closing, plates, of the lower jaw, prevalence of mid- and fine-meshed bone pattern, disturbed spatial orientation and thinning of bone trabeculae, as well as the development of pathologies in the periodontium.

Maxillary hypoplasia is one of the forms of class III malocclusion. On average, 60%  class III malocclusions are characterized by maxillary underdevelopment in all three directions. Anomalies in position, size and the shape of facial bones, maxilla in particular, usually appear in childhood, become more pronounced in adolescence until the end of the growth period. The aim of the paper is to show the camouflage treatment of the patient in adolescence with maxillary hypoplasia. Using the RME method in the upper jaw, extraction in the lower jaw and fixed orthodontic devices in both jaws, a satisfactory result was achieved.

Aim: to study the dynamics of the structural and functional state of the skeletal system, vitamin D3 content in patients with primary hyperparathyroidism (PHPT) during treatment, depending on age, duration of the disease, variant of menstrual function, development of recommendations for the prevention and treatment of endocrine osteoporosis. Material and research methods: 12 women with a bone form of PHPT were examined. To study the dynamics of the structural and functional state of the skeletal system, all patients were divided into two groups. Patients in the 1st group noted changes in gait, pain in the feet. In patients of the 2nd group there was loosening and loss of teeth, bone pain. During the illness, everyone had a decrease in body weight and a decrease in growth. In all patients of the 1st and 2nd groups, multiple fractures of the ribs and ilium were noted. All patients of the 2nd group showed arterial hypertension. The study found that the actual calcium intake was less than WHO recommended. There was a decrease in the level of vitamin D3 total in the blood serum of patients in both groups. In women of the 2nd group, the availability of vitamin D3 was significantly lower than in the 1st group patients (p <0.05). The examined women of both groups showed hypercalcemia, an increase in parathyroid hormone, urinary hydroxyproline excretion, osteoporosis diagnosed by X-ray morphometry, ultrasound osteodensitometry, and the FRAX algorithm. All women underwent surgical treatment – removal of parathyroid adenoma. In the postoperative period, patients received calcitriol and calcium preparations. An X-ray examination determined the consolidation of fractures of the ribs and iliac bones. The restoration of bone structure was slower in patients of the 2nd group.

Simple bone cyst (SBC) of the jaws is uncommon, representing approximately 1% of all jaw cysts. It is often accidentally discovered on routine dental examination as it is asymptomatic in most of cases. In this report, we discuss a case of SBC in a 16 years old female who presented in our department for correction of her mal-aligned teeth. On routine x-ray for orthodontic treatment, a well defined, unilocular radiolucent area approximately 3x1cm in size with scalloped borders on the left body of mandible expanding from distal surface of 34 to distal surface of 37 was discovered. Surgical exploration was required for both diagnostic and definitive treatment. The operative finding was hollow cavity without any epithelial lining.

1. Background: Loss of permanent teeth is very common, affected chewing function, speech and aesthetics; restoration of missing teeth with dental implant has several advantages, but we need thoroughly study the clinical and X ray features at the position at missing teeth, then to select the type of implant and make the best plan for the dental implant patients. 2. Materials and method: Cross-section descriptive study. From January 2009 to November 2010, study with 56 patients with 102 implants of MIS and Megagen systems at the Faculty of Odonto-Stomatology, Hue College of Medicine and Pharmacy and Vietnam-Cuba Hospital in Ha Noi. 3. Results: Distributed equally in male and female, common ages 40 – 59 (55,4%), the majority of missing teeth occurs in the lower jaw (63,8%) and especially, the teeth 36 and 46 (25,4%). The majority of missing teeth due to dental caries, dental pulp and apical diseases (64,7%) of the molar teeth (51,9%); the most position of missing tooth have enough bone for dental implants (87,3%), time of tooth loss and bone status in the position of tooth loss are related to each other (p < 0,01). Diameter and length of implant usually used 4.0 – 6.0 mm (63,7%) and 8.5 – 13.0 mm (83,3%). 4. Conclusion: Clinical and X ray features of edentulous patients has an important role in determining the type of implants and treatment planning of dental implants. Key words: Loss of permanent teeth, X ray and clinical features, Dental implant.
