Periodontitis

Periodontitis is a chronic inflammatory disease that affects the supporting structures of the teeth, including the gums, periodontal ligament, and alveolar bone.
It is characterized by progressive destruction of these structures, leading to tooth loss if left untreated.
Periodontitis is caused by a complex interplay between oral bacteria, host immune response, and various risk factors such as smoking, diabetes, and poor oral hygiene.
Early detection and appropriate management are crucial to prevent the progression of this disease and maintain oral health.
Effective periodontal disease research is essential for developing new treatment strategies and improving patient outcomes.

A detailed description of each study is included in (Supplementary Data 1 and 2).
In nine studies, analysis was conducted in individuals of European ancestry (ARIC, COHRA1, DRDR, MDC, NFBC1966, SHIP, SHIP-TREND, TWINGENE and WGHS). In one study (HCHS/SOL), participants were recruited from Hispanic and Latino communities in the USA, who self-reported ancestry from six broad groups (Cuban, Dominican, Mexican, Puerto Rican, Central American and South American). To undertake analyses within this highly admixed population, a bespoke modelling approach was undertaken. Multi-dimensional clustering was used to generate genetic analysis groups containing participants of similar ancestry. These group allocations were then used as covariates in a linear mixed model (partitioned to only fit the proportion of genetic structure due to familial relatedness rather than ancestry) alongside the first five genetic principal components, study center and log-transformed sampling weights53 (link). Subsequently, the results from HCHS/SOL were treated as a study of European ancestry and included in the primary meta-analysis.
For periodontitis only, there were two studies with participants of East Asian ancestry (BBJ, TMDUAGP), totalling 17,287 participants. For periodontitis, separate meta-analyses were performed for studies of European ancestry and studies of East Asian ancestry.

This clinical study was approved by the University of Michigan Health Sciences Institutional Review Board and registered with the clinical trials database of the National Institutes of Health, Bethesda, Maryland. Research subjects were recruited from September 2005 through June 2006. Upon receiving written consent, 100 human subjects aged 18 years and older were evaluated at the Michigan Center for Oral Health Research. All subjects possessed ≥20 teeth and had received no periodontal treatment or antibiotic therapy for medical or dental reasons 3 months prior to the investigation. In addition, the subjects did not previously undergo any long-term use of medications affecting periodontal status, such as anti-inflammatory drugs.
Subjects were enrolled into a healthy/gingivitis population (n = 50) or a periodontitis population (n = 49; one patient dropped out at experimental baseline). Subjects from the healthy and gingivitis population exhibited <3 mm of attachment loss, no periodontal probing depth (PD) >4 mm, and no radiographic alveolar bone loss. Periodontitis subjects exhibited at least four sites with evidence of radiographic bone loss, at least four sites with attachment loss >3 mm, and at least four sites with PD >4 mm (Fig. 1).
Subjects were excluded if they possessed a history of metabolic bone diseases, autoimmune diseases, unstable diabetes, or postmenopausal osteoporosis. Women who were pregnant were also excluded from the study.

The videos were analyzed by two independent calibrated examiners (HB und SE) using the software Mangold Interact 14 (Mangold International GmbH, Arnstorf, Germany). Brushing hand was coded and the examiners watched the video multiple times (also in slow motion) in order to code further behavioral categories. Calibration was provided by five videos of individuals not involved in the present study.
In adulthood, caries manifests primarily at lateral and proximal surfaces [15 (link)–17 (link)]. The risk of developing gum disease and periodontitis increases and exceeds that of caries [2 , 5 (link)]. Therefore, special emphasis was given to brushing behavior at lateral surfaces. Analyses regarding brushing movements and precise localization of brushing (sextants) were confined to them. To ensure that these analyses were not contaminated by occlusal brushing, lateral brushing was only assumed if both raters agreed that it was not occlusal. Thus, both examiners coded tooth contact time (time while toothbrush touches the teeth, without rinsing, spitting, tongue cleaning or breaks) and surfaces (vestibular, palatinal and occlusal) for all participants. SE carried out all further ratings and confined these to the palatinal and vestibular surfaces. These were: brushing movements (horizontal i.e. scrubbing, vertical, circular, modified Bass technique) and sextants (sextant 1 to 6, and, at vestibular surfaces, also concurrent brushing of antagonistic sextants, i.e. 1 and 6, 2 and 5, 3 and 4, respectively). Concurrent brushing of antagonistic sextants was coded when participants closed the mandibles while brushing. For further analyses, the brushing time of two sextants brushed concurrently was distributed in equal parts to both sextants.
To assess whether codings of sextants and movements remained reliable over time, double codings of a random sample of films were performed by HB. SE did not know which films were double coded and HB did not know SE’s codings. Intraclass correlations of double codings of the various observational categories were all above 0.801.
In the former study [13 (link)], all behavioral parameters were assessed by two independent examiners. Their intraclass correlations regarding the different parameters exceeded ICC = 0.865. For the present analyses, we computed the mean values of these double codings, since aggregating double codings further increases their reliability.
It was also intended to assess interdental cleaning (i.e. any application of devices for interdental cleaning in interdental spaces). However, only 15 participants performed interdental cleaning. Furthermore, most of these applied them only in some interdental spaces. We therefore refrained from any further analysis of this behavior.
A main result of the former study was that participants neglected surfaces and sextants while brushing. In the present analysis, a scoring system was thus developed allowing further description and analysis of the quality of toothbrushing at palatinal and vestibular surfaces (Quality index of toothbrushing regarding brushing time in sextants: QIT-S; for details see Table 1).

The Quality index of toothbrushing regarding brushing time in sextants (QIT-Sa)

QIT-S-00 sextants brushed by more than 1 s
QIT-S-11 sextants brushed by more than 1 s
QIT-S-22 sextants brushed by more than 1 s
QIT-S-33 sextants brushed by more than 1 s
QIT-S-44 sextants brushed by more than 1 s
QIT-S-55 sextants brushed by more than 1 s
QIT-S-6all sextants brushed by more than 1 s
QIT-S-7all sextants brushed by more than 3.5 s
QIT-S-8all sextants brushed by more than 5 s
QIT-S-9all sextants brushed by more than 7.5

aThe QIT-S index represents a rank-scaled measure allowing for the differential analysis of brushing time distribution at palatinal and vestibular sites, respectively. Brushing time of less than 1 s within a sextant is considered neglect of this sextant. QIT-S-0 ─ QIT-S-6 describe the expansion of this neglect. The highest score (QIT-S-9) is deduced from a recommended total brushing time of 2 min (e.g. 19 [19 ]; 18 [18 ]; 20 [20 ]) and an estimation of 30 s brushing time for occlusal surfaces as occlusal brushing is easier and can be done with greater movements than palatinal or vestibular brushing. Thereby, 45 s remain for the palatinal and vestibular surfaces, respectively. An even distribution of this time across sextants results in 7.5 s per sextant. As 3.5 represents roughly half of 7.5 this is taken as further step (QIT-S-7) and as 5 s per sextant might already be considered fair this was taken as another step (QIT-S-8)

The SOALS was initiated in 2011 to evaluate the bi-directional, longitudinal association between periodontitis and glucose abnormalities over a three-year period. Detailed descriptions of the study have been published elsewhere (Andriankaja et al., 2015 (link), Rivera et al., 2016 (link)). Briefly, we recruited individuals aged 40-65 years who were overweight or obese (body mass index (BMI)≥25 kg/m2) and free of clinically diagnosed diabetes from the San Juan municipality area. People were excluded if they had less than four natural teeth, a history of conditions that increase the risk of systemic complications during a periodontal exam, or inability to complete study procedures. Participants were also excluded if they met any of the American Diabetes Association criteria for diabetes (2011) (link).
Of 2,626 adults screened to determine eligibility, 695 were excluded based on the criteria described above. Once the screening process concluded, 1,931 adults were deemed eligible, 1,610 agreed to be scheduled for the baseline visit, and 1,451 adults attended the visit. During the baseline visit, additional eligibility criteria were further assessed and an additional 245 participants were excluded. Of the remaining 1,206 participants, 15 were excluded due to missing data on key variables for analyses; thus, the final sample size comprised 1,191 diabetes-free participants. The University of Puerto Rico Institutional Review Board approved the study, and all participants gave written consent prior to completing the study procedures. For the current study, a completed STROBE checklist is provided as a supplementary file (see Additional File 1).

A buccal gingival sample from either healthy or periodontitis-affected tissue from the premolar/molar maxillary region of each animal was taken using a standard gingivectomy technique, and maintained frozen in RNAlater solution. Total RNA was isolated from each gingival tissue using a standard procedure as we have described and tissue RNA samples submitted to the microarray core to assess RNA quality analyze the transcriptome using the GeneChip® Rhesus Macaque Genome Array (Affymetrix) (Meka, Bakthavatchalu, Sathishkumar, Lopez, Verma, Wallet, Bhattacharyya, Boyce, Handfield, Lamont, Baker, Ebersole and Kesavalu, Gonzalez, Stromberg, Huggins, Gonzalez-Martinez, Novak and Ebersole, 2011 (link)). Individual samples were used for gene expression analyses. Table 1 provides an overview of the genes whose expression was evaluated in the gingival tissues as related to M1/2, M1, and M2 phenotype macrophages. These include an array of cytokine/chemokine responses, as well as various cell surface molecules that provide some discrimination among these phenotypes.
Based upon the microarray outcomes we selected 5 genes and performed a qPCR analysis using a standard technique in our laboratory employing a Roche 480 LightCycler (Gonzalez, John Novak, Kirakodu, Stromberg, Shen, Orraca, Gonzalez-Martinez and Ebersole, 2013 (link)). Primers were prepared for IL6 (forward - CCTGAACCAACCACAAATGC; reverse – GGACTGCAGGAACTCCTTAAA; amplicon 114 bp), CXCL13 (forward – AGTCT GGAAGAAGAACAAGTCAG; reverse – GGAACTGGTGGAGTTGAAGAA; amplicon 108 bp), CCL19 (forward - GCTACCTTCTCATCAAGGATGG; reverse – GTTCTACCCAG GACTGGTCT; amplicon 102 bp), CD14 (forward - GCCCTAAACTCCCTCAATCTG; reverse – CAGTCTGTTGCAGCTGAGAT; amplicon 99 bp) and IL1R2 (forward – TTTCAGACACTACGCACCAC; reverse – ACCGTCTGTGCATCCATATTC; amplicon 118 bp) and GAPDH (forward – GGTGTGAACCATGAGAAGTATGA; reverse – GAGTCCTTCCACGATACCAAAG; amplicon 123 bp) genes, designed using software PrimerQuest at Integrated DNA Technologies website (www.idtdna.com) and were synthesized by Integrated DNA Technologies, Inc (Coralville, IA). The level of message was determined (Gonzalez, John Novak, Kirakodu, Stromberg, Shen, Orraca, Gonzalez-Martinez and Ebersole, 2013 (link), Gonzalez, Novak, Kirakodu, Orraca, Chen, Stromberg, Gonzalez-Martinez and Ebersole, 2014 (link), Ebersole, Kirakodu, Novak, Stromberg, Shen, Orraca, Gonzalez-Martinez, Burgos and Gonzalez, 2014 ) and those levels compared across the RNA samples prepared from each of the healthy groups and the 2 periodontitis groups.
