    Objective: The aim was to evaluate the association of behavioural and socioeconomic factors with the occurrence of periodontal disease and dental caries, paying special attention to the simultaneous occurrence of these diseases. Materials and methods: The study population consisted of 5255 dentate persons aged >= 30 years from a nationally representative survey. Caries and probing pocket depth were recorded by tooth and calculated in relation to the number of existing teeth. The groups were: non-affected (A), the two most affected quintiles for periodontal disease with little or no dental caries (B), the two most affected quintiles for dental caries with little or no periodontal disease (C) and the two most affected quintiles for both periodontal disease and dental caries (D). Presence of dental plaque was determined, and behavioural and socioeconomic factors were established. Results: Dental plaque, smoking, lack of regular dental check-ups, older age and a basic level of education were strongly associated with the simultaneous occurrence of periodontal disease and dental caries. Conclusions: There are many behavioural and socioeconomic factors that associate with the occurrence of both periodontal disease and dental caries. These factors also increase the risk of individuals having these diseases simultaneously.

    Parodontiitti ja diabetes ovat kroonisia, monitekijäisiä sairauksia, joiden kaksisuuntainen yhteys on ollut runsaan tutkimuksen kohteena. Molemmat ovat yleisiä, alidiagnosoituja sairauksia Suomen väestössä. Tämän kirjallisuuskatsauksena toteutettavan tutkielman tavoitteena on tarkastella parodontiitin ja diabeteksen patofysiologisia vuorovaikutusmekanismeja ja parodontologisen hoidon merkitystä diabeteksessa sekä arvioida näiden kliinistä merkitystä diabetespotilaita hoitavan lääkärin ja hammaslääkärin työssä. Tutkielmaa varten on perehdytty aiheeseen liittyviin tutkimuksiin ja kirjallisuuteen. Tutkimusten perusteella diabetespotilaat ovat suuremmassa riskissä sairastua parodontiittiin ja kiinnityskudostuho on heillä vaikea-asteisempaa. Diabeteksesta johtuvat hyperglykemia ja lipidimetabolian muutokset kiihdyttävät tulehdusta parodontaalikudoksissa muun muassa lisäämällä paikallisia proinflammatorisia sytokiineja, reaktiivisia happijohdannaisia, AGE/RAGE interaktioita ja RANKL/osteoprotegeriinin aktivaatiota. Parodontiitin aiheuttama systeeminen tulehduskuorma voi heikentää diabetespotilaan verensokeritasapainoa ja lisätä riskiä diabetekseen liittyviin komplikaatioihin. Diabetesta sairastamattomilla parodontiitti lisää riskiä sairastua prediabetekseen ja tyypin 2 diabetekseen. Parodontologisella hoidolla saattaa olla suotuisia vaikutuksia sokerihemoglobiinin ja lipidiprofiiliin tyypin 2 diabetesta sairastavilla. Diabetespotilaan suun terveys vaatii erityishuomiota hammaslääkäreiltä ja lääkäreiltä. Diabeteksen huono hoitotasapaino korreloi merkittävästi iensairauksien ongelmiin. Hoitamaton parodontiitti puolestaan voi suurentaa veren glukoosipitoisuutta.

    Aim: This study aimed to investigate the association between salivary levels of myeloperoxidase (MPO), neutrophil elastase (NE), soluble urokinase-type plasminogen activator receptor (suPAR), matrix metalloproteinase (MMP)-8 and tissue inhibitor of matrix metalloproteinases (TIMP)-1 and gingival inflammation development during an experimental gingivitis study. Methods: A three-week experimental gingivitis study was conducted. Clinical recordings of dental plaque biofilm (Modified Quigley Hein Plaque Index, TQHPI) and gingival inflammation (Modified Gingival Index, MGI) were made at specific time points for each of the 42 participants. Salivary levels of MPO, NE, suPAR, MMP-8 and TIMP-1 at the same time points were measured using distinct immunoassays. For data analysis growth curve modelling was employed to account for the time-varying outcome (MGI score) and the time-varying covariates (salivary marker levels, and TQHPI score). Analyses were stratified according to the MGI-score trajectory groups previously identified as 'fast', respectively 'slow' responders. Results: Overall, higher MGI scores were statistically significantly positively associated with higher levels of MPO, MMP-8 and TIMP-1. Stratified analysis according to inflammation development trajectory group revealed higher levels of salivary MPO, MMP-8 and MMP-8/TIMP-1 ratio among the 'fast' responders than among 'slow' responders. None of the investigated salivary protein markers was associated with a 'slow' inflammation development response. Conclusions: Salivary levels of MPO, MMP-8 and TIMP-1 were associated with the extent and severity of gingival inflammation. While the 'fast' gingival inflammation response was associated with increased levels of MPO, MMP-8 and MMP-8/TIMP-1 ratio, the 'slow' response was not associated with any of the salivary protein markers investigated in this study. Neutrophil activity seems to orchestrate a 'fast' gingival inflammatory response among participants previously primed to gingival inflammation.
