The association between caries and periodontal diseases

Objectifs: Le but de cette étude clinique était de comparer un groupe d’adultes ayant un parodonte sain avec un groupe d’adultes atteints de parodontite chronique en terme de risque carieux et mesures cliniques et microbiologiques de la carie. Méthodes: Quatre-vingt-seize individus ont été divisés en deux groupes en fonction de leur état de santé parodontal et ont été appariés pour l'âge, le sexe et l'origine ethnique. Trente-huit sujets étaient atteints de parodontite chronique définie comme ayant au moins quatre dents avec ≥ 1 site avec une profondeur de sondage ≥ 4 mm et une perte d'attache clinique ≥ 2 mm, et 58 sujets présentaient un parodonte sain. Par la suite, les groupes ont été subdivisés en deux groupes en fonction de leur statut carieux : les participants ayant au moins une lésion carieuse non traitée sur une surface dentaire et ceux n’ayant pas de lésion carieuse non traitée. Les données ont été recueillies par le biais d’un questionnaire, un examen clinique et des échantillons de plaque supra- et sous-gingivale. L’évaluation de la charge buccale de Streptococcus mutans et de six agents pathogènes parodontaux a été réalisée par la technique d'amplification de la réaction en chaine de la polymérase (PCR). Les données ont été analysées à l'aide d’analyses statistiques descriptives et bivariées. Résultats: Les individus atteints de parodontite chronique étaient 3,5 fois plus susceptibles d'avoir des caries que les individus en bonne santé (OR 3,5 ; IC: 1,5 - 8,3 ; P = 0,006). Les sujets à la fois atteints de parodontite chronique et de caries dentaires ont eu un niveau d’éducation significativement plus faible que les sujets ayant un parodonte sain et sans caries dentaires (OR 6,0 ; IC: 1,7 à 21,7 ; P = 0,04). La proportion de sujets ayant une charge buccale élevée de Porphyromonas gingivalis (P. g.) et Treponema denticola (T. d.) était significativement plus élevée chez les patients atteints de parodontite chronique et de carie que chez les patients sains présentant des caries (P. g.: OR 8,6 ; IC: 2,4 - 30,3 ; P = 0,004 et T. d.: OR 10,0 ; CI: 2,6 - 38.1 ; P = 0,003). Conclusions: Les résultats de cette étude suggèrent que, chez les sujets adultes atteints de la parodontite chronique, la fréquence des caries est plus élevée que chez les sujets ayant un parodonte sain. De plus, le faible niveau d'éducation influence négativement le statut parodontal des individus.

Spectroscopic Investigation of Tooth Caries and Demineralization

Dental caries persists to be the most predominant oral disease in spite of remarkable progress made during the past half- century to reduce its prevalence. Early diagnosis of carious lesions is an important factor in the prevention and management of dental caries. Conventional procedures for caries detection involve visual-tactile and radiographic examination, which is considered as “gold standard”. These techniques are subjective and are unable to detect the lesions until they are well advanced and involve about one-third of the thickness of enamel. Therefore, all these factors necessitate the need for the development of new techniques for early diagnosis of carious lesions. Researchers have been trying to develop various instruments based on optical spectroscopic techniques for detection of dental caries during the last two decades. These optical spectroscopic techniques facilitate noninvasive and real-time tissue characterization with reduced radiation exposure to patient, thereby improving the management of dental caries. Nonetheless, a costeffective optical system with adequate sensitivity and specificity for clinical use is still not realized and development of such a system is a challenging task.Two key techniques based on the optical properties of dental hard tissues are discussed in this current thesis, namely laser-induced fluorescence (LIF) and diffuse reflectance (DR) spectroscopy for detection of tooth caries and demineralization. The work described in this thesis is mainly of applied nature, focusing on the analysis of data from in vitro tooth samples and extending these results to diagnose dental caries in a clinical environment. The work mainly aims to improve and contribute to the contemporary research on fluorescence and diffuse reflectance for discriminating different stages of carious lesions. Towards this, a portable and compact laser-induced fluorescence and reflectance spectroscopic system (LIFRS) was developed for point monitoring of fluorescence and diffuse reflectance spectra from tooth samples. The LIFRS system uses either a 337 nm nitrogen laser or a 404 nm diode laser for the excitation of tooth autofluorescence and a white light source (tungsten halogen lamp) for measuring diffuse reflectance.Extensive in vitro studies were carried out on extracted tooth samples to test the applicability of LIFRS system for detecting dental caries, before being tested in a clinical environment. Both LIF and DR studies were performed for diagnosis of dental caries, but special emphasis was given for early detection and also to discriminate between different stages of carious lesions. Further the potential of LIFRS system in detecting demineralization and remineralization were also assessed.In the clinical trial on 105 patients, fluorescence reference standard (FRS) criteria was developed based on LIF spectral ratios (F500/F635 and F500/F680) to discriminate different stages of caries and for early detection of dental caries. The FRS ratio scatter plots developed showed better sensitivity and specificity as compared to clinical and radiographic examination, and the results were validated with the blindtests. Moreover, the LIF spectra were analyzed by curve-fitting using Gaussian spectral functions and the derived curve-fitted parameters such as peak position, Gaussian curve area, amplitude and width were found to be useful for distinguishing different stages of caries. In DR studies, a novel method was established based on DR ratios (R500/R700, R600/R700 and R650/R700) to detect dental caries with improved accuracy. Further the diagnostic accuracy of LIFRS system was evaluated in terms of sensitivity, specificity and area under the ROC curve. On the basis of these results, the LIFRS system was found useful as a valuable adjunct to the clinicians for detecting carious lesions.

Resumen tomado de la publicación

Prevalence and severity of dental caries in schoolchildren of Porto, Portugal

Objectives: To measure the prevalence and severity of dental caries in adolescents of the city of Porto, Portugal, and to assess socioeconomic and behavioural covariates of dental caries experience. Methods: A sample of 700 thirteen-year-old schoolchildren was examined. Results from the dental examination were linked to anthropometric information and to data supplied by two structured questionnaires assessing nutritional factors, socio-demographic characteristics and behaviour related to health promotion. Dental caries was measured using the DMFT index, and two dichotomous outcomes, one assessing the prevalence of dental caries (DMFT>0); the other assessing the prevalence of a high level of dental caries (DMFT=4). Results: Consuming soft drinks derived from cola (irrespective of sugared or diet) two or more times per week, attending a public school, being female and having parents with low educational attainment were identified as risk factors both for having dental caries and for having a high level of dental caries. Conclusion: Caries levels were positively associated with frequency of intake of sweetened foods and drinks.

Untreated dental caries in children with cerebral palsy in the Brazilian context

Objectives. To assess the prevalence of untreated dental caries in children with cerebral palsy and to assess socio-demographic, behavioural, and clinical covariates. Design. Cross-sectional assessment of 200 children and adolescents with cerebral palsy (2-17 years old) enrolled in a specialized healthcare unit in Sao Paulo, Brazil. The dental examination followed the World Health Organization`s guidelines for oral health surveys; familial caretakers informed on socio-economic status and behaviour; the patient`s medical record informed their clinical status. Results. The proportion of children that presented at least one tooth affected by untreated caries was 49.5%. Poor socio-economic standings and a higher frequency of sugar consumption associated with a worse profile of dental health; different types of cerebral palsy (spastic, tetraparesis) did not. The prevalence of untreated caries was higher than reference values assessed for the overall population of the same age range. Conclusions. The high burden of untreated dental caries on cerebral palsy patients reinforces the importance of the dentist in the interdisciplinary healthcare team attending these children. Factors associated with this outcome are the same for the general population; these findings underscore the necessity of implementing effective caries prevention in this population of cerebral palsy children.
