Chapter 10: Oral Health-Related Quality of Life and Coronal Caries.

Dental caries is the most prevalent oral health disease and affects the health of individual and populations. The conventional disease metrics do not represent the impact of caries on people's lives. Oral-health-related quality of life measures were developed to help understand which aspects of dental caries have the greatest impact on well-being. How these measures were developed follows a standardized process of development and testing, with the ultimate aim of the entire process being that they be used in clinical dentistry, dental epidemiology, and health services research. There has been ongoing debate about whether these measures have adequate discriminative ability for the wide range of caries experience, and whether they are responsive to changes in disease experience. Whether these measures are "perfect" or not, what we do know after two decades is that numerous studies have found them to be sufficiently discriminative for caries in adults and children alike. There is also evidence for their responsiveness, chiefly from studies of children undergoing dental treatment under general anesthetic for early childhood caries. The influence of environmental, social, and psychological characteristics is another consideration in how people self-rate their oral health. Is there a need to improve the quality of these measures by refining existing ones or developing new ones which may represent those broader concepts? Regardless of the future, the most pressing challenge is the need for health systems work to ensure the routine use of these measures in clinical and public health practice.

Treatment of pre-eruptive intracoronal resorption: A scoping review.

Pre-eruptive intra-coronal resorption (PEIR) is a rare condition that can affect children's dentition. Showing the same aspect of dental caries, these lesions are diagnosed in non-erupted teeth. The aetiology is not yet defined and no consensus on their treatment is available. Thus, the aim of the present scoping review of the literature was to try to establish a protocol for treatment and management of PEIR defects. The search was performed on Medline via PubMed, Science Direct and EBSCOhost' databases using the appropriate Medical Subject Headings (MESH) terms. Studies that described the PEIR were considered eligible and the data from the selected papers were extracted and analysed independently by two authors. Out of 172 articles identified in initial research, 15 articles were selected for reviewing. Interventions varied from preventive treatment to extraction, depending on the lesion severity and its proximity to the pulp. Non-operative procedures, conservative approaches and extractions were recommended for the management of PEIR, depending on the extent of the lesions. Overall, further researches should be conducted to explore the effectiveness of the approaches of PEIR management.

Molecular-Genetic Mechanisms of Caries Development

This review analyzes the literature in the rapidly developing direction of genetic aspects of caries. The search by key words “genetic markers of caries” in the PubMed database was performed. Afterwards, an analysis of the literature lists of found publications was completed and additional sources were studied. Search by “caries” on the platform of elibrary.ru was performed. From the published data, the role of markers by spectrum of genes in caries development is obvious; however, the development of caries is influenced not only by genetic factors but also by environmental factors. The established molecular-genetic markers of caries development, including genes connected with immunity, saliva content, and rate of saliva formation and also connected with formation of teeth, dentin, and tooth enamel are considered. Social demographic factors and environmental factors (dietary peculiarities, hygiene of mouth cavity, contamination of environment, content of mouth microbiota) influencing caries development are considered. Information from literature sources will help to characterize the modern understanding of caries development and will also make it possible to perform both individual and population screening aiming to develop novel methods of caries prevention taking into account the detected markers of caries, establish groups of risk, and apply a personalized approach in the treatment of the disease.

Cloning of a locus involved in Streptococcus mutans intracellular polysaccharide accumulation and virulence testing of an intracellular polysaccharide-deficient mutant.

The streptococcal transposon Tn916 (Tcr) was used to isolate mutants of Streptococcus mutans altered in glycogen accumulation to investigate whether glycogenlike intracellular polysaccharides (IPS) play an important role in S. mutans-induced caries formation. S. mutans UA130 (serotype c) was transformed with the Escherichia coli plasmid pAM620 (Tn916), and the resultant transposon libraries were screened for glycogen content by iodine staining. A transposon mutant, designated SMS201, demonstrated a glycogen-deficient phenotype on glucose-enriched medium. Quantitative electron microscopy confirmed that IPS concentrations were significantly reduced in SMS201 relative to the wild-type progenitor strain, UA130. Importantly, reversion to wild type correlated at all times with loss of the transposon. Transposon excisants were used to facilitate cloning of the streptococcal gene(s) involved in glycogen biosynthesis and storage. A 2.1-kb chromosomal determinant (glgR) which encodes a putative regulator of S. mutans glycogen accumulation was isolated. A stable deletion mutation (delta glgR) was subsequently generated in E. coli and introduced into S. mutans by allelic exchange. The resultant glycogen synthesis-deficient mutant, SMS203, demonstrated a significantly reduced cariogenic potential (P less than 0.01) on the buccal, sulcal, and proximal surfaces of teeth in germfree rats, relative to animals challenged with the glycogen synthesis-proficient progenitor strain, UA130. These observations confirm previous reports (J. M. Tanzer, M. L. Freedman, F. N. Woodiel, R. L. Eifert, and L. A. Rinehimer, p. 597-616, in H. M. Stiles, W. J. Loesche, and T. L. O'Brien, ed., Proceedings in Microbiology. Aspects of Dental Caries. Special Supplement to Microbiology Abstracts, vol. 3, 1976) which implicate IPS as significant contributors to the S. mutans cariogenic process.
