Dental specialties and subspecialties

Student Clinic

The student clinic treats patients with caries disease and at risk of the disease. The treatment aims to slow down the caries disease before the damage becomes so great that it needs to be repaired and, of course, to repair the damage that has gone too far to slow down, i.e. "repair teeth". Students work under the supervision of dentists with specialised expertise in the field. Caries treatment, therefore, aims to ensure that the patient does not suffer any new damage or that minor damage is made worse. The usual dental filling aims to remove irreparably damaged tooth substance, close the defect and restore the function of the tooth.

The Clinic

The clinic treats patients on referral from general practitioners, specialist dentists in the region and other departments of the Faculty of Odontology. Dentists with specialised and in-depth expertise in the subject carry out diagnosis, risk assessment and treatment with the help of specially trained dental nurses. Common reasons for referral are special cariological diagnostics, risk and prognosis assessment and treatment of caries risk that is difficult to assess, treatment of carious disease with complicated causes (e.g. dry mouth after radiotherapy or Sjögren's syndrome), diseases that affect dietary habits, eating disorders, etc.

As part of the caries risk assessment and determination of the causes of caries in individual cases, saliva samples are taken. The samples are analysed for flow rate, buffering capacity and the presence of caries-causing bacteria. A cariogram is used to help with risk assessment and patient information. Investigation of other changes in the hard tissues of the teeth such as tooth development disorders and erosion damage are other reasons for referral. Patients are also referred because of technically difficult fillings.

The subject of Cariology includes diagnostics and treatment of caries and erosions, its causes and defence factors, as well as risk assessment and preventive measures regarding both caries and erosions. The treatment includes individually adapted preventive and disease-treating measures as well as operative treatment with the aim of maintaining or improving oral health and thus general health.

Within the subject, it is considered that medical, psychosocial, economic and social factors, dental care habits and more, can affect caries disease and its course. If necessary, motivational talks are held to initiate behavioural change, for example changing unfavourable dietary habits. The subject also includes diagnostics and treatment of congenital or acquired defects and damage in the hard tissues of the tooth.

Research

The research deals with various aspects of caries where the focus is on caries from different perspectives such as microbiological and immunological aspects as well as the importance of hereditary factors. Research with a salutogenic (health-promoting) perspective is also conducted within the subject, with a focus on health factors rather than risk factors. The research is often conducted in collaboration with surrounding dental care and other scientific fields.

Student Clinic

The student clinic treats patients with pulpitis (inflammation of the tooth pulp) and apical periodontitis (infection of the root canal system). Students work under the supervision of specialist dentists or dentists with specialised expertise in the field. Root canal treatment is a relatively time-consuming process, generally requiring several treatments to completely clean the tooth's root canals and remove any bacteria that may be present. Once the root canals are deemed clean, they are completely filled and the tooth is repaired with a filling or crown to prevent any bacteria from leaking back in from the oral cavity. Follow-up of root canal treatments performed at the student clinic shows that the treatments are of high quality.

Teacher's clinic

The teaching clinic treats patients on referral from general practitioners, from specialist dentists in the region and from other subjects at the School of Dentistry. Endodontic specialists, dentists undergoing specialist training or dentists with specialised expertise in the subject perform the treatments. As an additional aid in performing complicated root canal treatments, we have an operating microscope, ultrasound technology, various file systems and the possibility of microbiological diagnostics.

Common reasons for referral for endodontic specialist care include technical difficulties such as difficulty in finding the root canals in the tooth or complicated tooth anatomy that makes treatment technically difficult, but also problems with diagnosis and prognosis assessment. Other reasons for referral are more severe root canal infections that have not healed despite root canal treatment and teeth that continue to cause discomfort or pain after root canal treatment. If necessary, the root canal treatment is supplemented with surgical treatment such as apical surgery (root canal surgery).

We also perform dental infection investigations in case of prevention or suspicion of a connection between dental infection and general health. Patients with dental fear are welcome and treatment under nitrous oxide sedation can be offered. We can admit patients with long-term pain symptoms who, if necessary, can be investigated further at the Orofacial Pain Unit.

Research areas in endodontics include infection control, the function of the pulp-dentin complex and diseases in or arising from the dental pulp. These diseases are called pulpitis (pulp inflammation in the vital pulp tissue in the tooth) and apical periodontitis (inflammation at the root tip of the tooth due to infection starting in the root of the tooth). The research involves the development of knowledge about how to prevent, diagnose, treat, and assess the prognosis of these diseases. The diseases are also studied at the societal level, i.e. how common it is with root tip inflammation in the population and what it is that affects the incidence.

The research conducted within endodontics is currently focused on the following areas: endodontic infection control in general dentistry (barriers & facilitators) clinical treatment research and development of digital research protocols, the effect of ultra vibrations on pulp tissue, pulp treatment for exposed pulp, long-term orofacial pain, quality of treatment, treatment outcomes, uncertainty in endodontics and decision making in endodontics.

Research and postgraduate training are conducted with a focus on temporomandibular joint diseases, hard and soft tissue regeneration before implant treatment, health economic aspects of wisdom tooth surgery, mucosal changes and bone healing related to smoking and drug-induced bone necrosis.

Within the subject of Materials Science and Technology, research and postgraduate training are conducted to develop and apply biocompatible materials and methods. The aim is to prevent, treat and maintain oral health and function in patients with clinical conditions associated with damaged or missing teeth and maxillofacial tissues. Research and teaching include clinic and laboratory activities, both nationally and internationally.

Within odontological x-ray diagnostics, research and postgraduate training are conducted with a focus on, among other things, digital quality assurance, improved risk assessment regarding caries, and jaw joints and cost-effectiveness when using Cone Beam Computed Tomography (CBCT) compared to conventional methods.

We work with translational and and applied clinical research on orofacial  diseases and conditions that are common in the population. The research is based on the patients' perspectives.

Our ambition is a broad research base that includes biology, individual, and society with a focus on mechanisms, diagnostics, evaluation of treatment, epidemiology and learning. The research should lead to better and more evidence-based knowledge in collaboration with our society. It is important for us that the new knowledge should benefit the care and with a special focus on patient's quality of life.

The research projects are often multidisciplinary and  conducted with both national and international collaborators.

Most of the infectious diseases of the mouth are caused by biofilms – macromolecules and microorganisms that attach to surfaces and form microbial communities. A prominent feature of biofilms that has clinical relevance is their strong resistance to host defence mechanisms and conventional treatments including many antimicrobial agents. In order to be able to control, modify or eliminate biofilms, it is therefore important to understand the mechanisms that make bacteria adapt and survive in the biofilm environment.

The focus of our work is on diseases in the oral cavity caused by biofilms. Our goal is to understand the mechanisms that create virulence, that is, cause oral bacteria to cause disease, in biofilms and to identify key points to prevent this process. The working hypothesis is that the development of virulence properties in oral biofilms is regulated by interactions with surface-associated macromolecules from saliva (eg mucins) and/or proteins from the gingival crevicular fluid. Flow cell models are used in combination with confocal scanning laser microscopy to study the adhesion of bacteria to a range of surfaces conditioned with saliva or serum. Phenotypic changes during biofilm development are investigated using a proteomic approach. In parallel with mechanistic studies, clinical trials are carried out in collaboration with Folktandvården to determine whether specific phenotypes can be used as biomarkers to identify patients at risk of disease. We anticipate that our results will contribute to the development of future antimicrobial therapies that target disease-inducing properties in biofilms instead of specific microorganisms.

A large part of the research focuses on mapping the oral health of the Scanian population, how the adult population in Scania, Sweden perceives their dental health and what dental care needs and dental care demands they have. The results of this research will, among other things, form the basis for planning and dimensioning dental care in Skåne.

Other current research projects are studies on the design of the clinical examination and financial and administrative gains and effects of a digital patient administrative record system.

Current research projects are about how diagnostics and treatment are affected by the new classifications of periodontitis, about the evaluation of oral care programs for patients treated for cancer in the head and neck region, and about the importance of saliva secretion and saliva composition for the experience of dry mouth.

The basis for our research is clinical problems that arise in the tissue samples (biopsies) that are sent in large numbers for diagnostics to the department. We conduct both clinical and experimental studies mainly around various aspects of inflammation, e.g. aberrant immune reactions in the oral mucosa but also regarding disease development and risk and prognosis assessment of tooth-related inflammation in the jawbone.

About 30% of the population has such deviations in the bite that they should be corrected. Untreated bite deviations can lead to risks for oral health and function as well as a negative impact on the individual's perceived oral health-related quality of life.

The orthodontics department in Malmö conducts evidence-based patient-centred research. The projects focus on evidence-based clinical research and primarily include evaluation of the oral health-related quality of life, treatment effectiveness, cost-effectiveness and side effects of orthodontic treatment. The research is part of the faculty's research environment: Orofacial functional disorders and pain. Orofacial dysfunction and pain is a summary of many clinical problems and diseases involving the bite and jaws, masticatory muscles and jaw joints and adjacent structures. Children, young people and adults are affected and the cause of the problems is usually multifactorial.

Research and postgraduate education include laboratory, translational and clinical activities, often in collaboration with national and international actors from academia, healthcare and industry. The research results are communicated via national and international publications, congresses, and other forums.

Pedodontics is an applied discipline in which basic knowledge from various odontological, medical and behavioural sciences is brought together and applied as an often modified form, adapted to well-defined characteristics of the constantly developing individual.

The cross-sectional nature of the subject area of ​​pedodontics is reflected in the department's research profile, which includes the following research areas:

• Evaluation of endodontic treatments at an early age
• Periodontal diseases in children and adolescents
• Immigrant children's dental health
• Caries prevention in children and young people
• Oral conditions and behaviour in dental care situations in premature infants
• The function of the small salivary glands at different ages.

We conduct research from the perspective of the patient, the care provider and society - often with a multidisciplinary approach. The questions are both basic biological and clinical and cover the entire range from molecule to human, from laboratory studies to registry studies and clinical studies. Our research topics are broad and encompass decision-making, biomaterials and reconstructive care as well as oral health-related quality of life. Current projects concern digital processing techniques, biomaterials development, adaptation and implementation, dental implants as well as the development of new and evaluation of existing treatment methods that include cost-effectiveness analysis and patients' quality of life.

Research in community dentistry is usually conducted in close collaboration with other subjects. The study of the spread of oral diseases in the population, i.e. the epidemiology of oral health, is central to the research. An important part of the research is also to understand the concept of health better and to create knowledge about the role of the mouth and teeth in the quality of life - oral rehabilitation can mean a great deal to people's lives. Development of methodology for an overall evaluation of clinical measures is part of that work, but also international comparative studies of oral quality of life to understand social and cultural meanings of the mouth and teeth.

Dental care organisation and the structure of the clinical decision-making process are other central areas of our research. The ambition of the research being conducted is to have an interdisciplinary approach, where organization, funding and psychology interact with biological and technical factors.
