Abstract
Periodontitis is a complex condition. Left untreated, it leads to tooth loss and the need for prosthetic treatment. The incidence of periodontitis is steadily increasing, so new methods are being sought to aid in the diagnosis of the disease. Among the methods postulated is the determination of concentrations of bioactive compounds which include extracellular matrix metalloproteinases (MMPs). These enzymes are present in various structural elements of the stomatognathic system. The most promising enzyme of this group appears to be metalloproteinase 8 (MMP-8). MMP-8 assays are performed in gingival fluid or saliva, and MMP-8 levels have been shown to be higher in patients with periodontitis compared to healthy subjects and correlated with some clinical parameters of the condition and the severity of the disease. In addition, the preliminary usefulness of this enzyme in evaluating the effectiveness of periodontal treatment and doxycycline therapy has been demonstrated. Determination of the active form of MMP-8 (aMMP-8) in oral rinse fluid using off-the-shelf assays shows the highest potential. Despite reports about aMMP-8 and promising data on the role of MMP-8 in periodontal diagnosis, a clear determination of the usefulness of this enzyme requires further research.

Patient discomfort and intensity of intraseptal anesthesia of computer-controlled articaine/epinephrine delivery for scaling and root planing. Clin Oral Investig 2023; 27:6221-6234.

Abstract
OBJECTIVES The primary aim was to assess the pain during intraseptal anesthesia (ISA) administration, as well as during and after scaling and root planing (SRP). The secondary aims pertained to comparing the pain in different jaw regions and evaluating the factors affecting pain during ISA administration, during and after SRP. MATERIAL AND METHODS ISA was obtained with three different doses of 4% articaine with 1:100,000 epinephrine (4%Ar + Ep) in 360 patients. The pain levels were measured using the visual analogue scales (VAS) for pain intensity during ISA administration (VASa), during SRP (VASi), and after SRP (VASp). These findings were then correlated with periodontal parameters. Regression analysis was performed for pain during ISA, during and after SRP. RESULTS Anesthesia administration was painful in 80.8% of cases. VASa negatively correlated with pocket depth (PPD). VASi showed no dose-dependency, except in mandibular premolars. VASi negatively correlated with the clinical attachment level (CAL). VASp positively correlated with PPD and CAL. Positive bleeding on probing reduced the chance of pain during ISA administration. Longer anesthesia duration and wider anesthetic field (orally) increased the prospects of painless SRP. CONCLUSIONS No dose-dependent differences were found regarding patient discomfort and pain intensity of ISA delivery of 4%Ar + Ep for SRP. CLINICAL RELEVANCE The pain during ISA administration was mild and well tolerated regardless of the anesthetic dose. A lower intensity of pain during SRP can be expected in patients with greater CAL. Post-treatment pain can be anticipated after SRP in the regions with greater PPD and CAL. CLINICAL TRIALS REGISTRATION NUMBER NCT04392804 (May 9th, 2020).

Abstract
Periodontitis is one of the most common oral diseases in humans, affecting over 40% of adult Americans. Pain-sensing nerves, or nociceptors, sense local environmental changes and often contain neuropeptides. Recent studies have suggested that nociceptors magnify host response and regulate bone loss in the periodontium. A subset of nociceptors projected to periodontium contains neuropeptides, such as calcitonin gene-related peptide (CGRP) or substance P (SP). However, the specific roles of neuropeptides from nociceptive neural terminals in periodontitis remain to be determined. In this study, we investigated the roles of neuropeptides on host responses and bone loss in ligature-induced periodontitis. Deletion of tachykinin precursor 1 (Tac1), a gene that encodes SP, or treatment of gingiva with SP antagonist significantly reduced bone loss in ligature-induced periodontitis, whereas deletion of calcitonin related polypeptide alpha (Calca), a gene that encodes CGRP, showed a marginal role on bone loss. Ligature-induced recruitment of leukocytes, including neutrophils, and increase in cytokines leading to bone loss in periodontium was significantly less in Tac1 knockout mice. Furthermore, intra-gingival injection of SP, but not neurokinin A, induced a vigorous inflammatory response and osteoclast activation in alveolar bone and facilitated bone loss in ligature-induced periodontitis. Altogether, our data suggest that SP plays significant roles in regulating host responses and bone resorption in ligature-induced periodontitis.

Abstract
The principles of periodontal therapy are based on the control of microbial pathogens and host factors that contribute to biofilm dysbiosis, with the aim of modulating the progression of periodontitis and periodontal tissue destruction. It is currently known how differently each individual responds to periodontal treatment, depending on both the bacterial subtypes that make up the dysbiotic biofilm and interindividual variations in the host inflammatory response. This has allowed the current variety of approaches for the management of periodontitis to be updated by defining the goals of target strategies, which consist of reducing the periodontopathogenic microbial flora and/or modulating the host-mediated response. Therefore, this review aims to update the current variety of approaches for the management of periodontitis based on recent target therapies. Recently, encouraging results have been obtained from several studies exploring the effects of some targeted therapies in the medium- and long-term. Among the most promising target therapies analyzed and explored in this review include: cell-based periodontal regeneration, mediators against bone resorption, emdogain (EMD), platelet-rich plasma, and growth factors. The reviewed evidence supports the hypothesis that the therapeutic combination of epigenetic modifications of periodontal tissues, interacting with the dysbiotic biofilm, is a key step in significantly reducing the development and progression of disease in periodontal patients and improving the therapeutic response of periodontal patients. However, although studies indicate promising results, these need to be further expanded and studied to truly realize the benefits that targeted therapies could bring in the treatment of periodontitis.

Abstract
Periodontitis is a chronic inflammatory disease of the gums. The incidence of periodontitis is increasing all over the world. In patients with periodontitis, there is gradual destruction of the periodontal ligament and the alveolar bone, and later, in advanced stages, there is tooth loss. Different microorganisms, the host’s immune response, and various environmental factors interact in the progression of this chronic inflammatory disease. In the present review, we discuss the epidemiology, clinical features, diagnosis, and complications of periodontitis. We also discuss the association of chronic inflammation found in periodontitis with various other systemic diseases, which include cardiovascular, respiratory, diabetes, Alzheimer’s, cancer, adverse pregnancy, and multiple myeloma, and also highlight microbial carcinogenesis and the microRNAs involved. The latest updates on the molecular mechanism, possible biomarkers, and treatment procedures may be beneficial for diagnostic and therapeutic purposes.

Abstract
PURPOSE Periodontitis progresses with chronic inflammation, without periodontal pain. However, the underlying mechanisms are not well known. Here, the involvement of butyric acid (BA) in periodontal pain sensitivity in Porphyromonas gingivalis (P. gingivalis)-induced periodontitis was examined. METHODS P. gingivalis was inoculated into the ligature which was tied around the molar (P. gingivalis-L) and the gingival mechanical head withdrawal threshold (MHWT) was measured. Following P. gingivalis-L, the expressions of orphan G protein-coupled receptor 41 (GPR41) in trigeminal ganglion (TG) neurons were examined. The amount of gingival BA was analyzed following the P. gingivalis-L and the changes in the MHWT in complete Freund's adjuvant (CFA)-injected gingival tissue by gingival BA were examined. The changes in the MHWT following P. gingivalis-L by gingival GPR41 antagonist (HA) were examined. RESULTS No change in the MHWT was observed, GPR41-immunoreactive TG neurons were increased following P. gingivalis-L. The gingival BA amount increased following P. gingivalis-L, and the gingival BA suppressed the decrease in MHWT following CFA. HA decreased MHWT following P. gingivalis-L. CONCLUSION Gingival BA modulates periodontal mechanical nociception via GPR41 signaling in P. gingivalis-L-induced periodontitis.

Abstract
BACKGROUND The aim of this study is to investigate the prevalence of localized intraoral neuropathic pain in a cluster of patients who reported the involvement of gingival site as only clinical manifestation of dysesthesia, analysing type and distribution of symptoms. MATERIAL AND METHODS Burning mouth syndrome (BMS) patients were enrolled in the study. Patients were screened through laboratory test and a conventional oral examination with periodontal chart. A questionnaire to collect data on symptoms, oral site involved, quality of sleep, anxiety was submitted to all the patients. RESULTS A total of 236 patients were recruited. Seventy-six patients (32.2%) presented generalized type, whereas 160 (67.8%) had localized type. In the localized BMS group, the gingiva was involved in 70 patients and in 33 of these it was the only site involved. In the gingival subgroup, 35 patients reported burning, 29 pain and 24 xerostomia. CONCLUSIONS To best our knowledge, this study is the first that analyses gingival involvement as the only site in BMS and it could encourage further investigations to understand the etiopathogenesis of gingival BMS.

Abstract
AIMS To determine impact of oral hygiene behaviour change intervention compared to the prevailing standard of oral hygiene advice provided in general dental practice, on bleeding on probing (BOP) in gingivitis patients, over 3-months. The effect of providing power-brushes was also evaluated. MATERIALS AND METHODS NHS dental practices were cluster-randomised to intervention or control (2:1). Dentists at intervention sites received behaviour modification training. Participants were stratified to high (≥20% BOP) or low (<20% BOP) presence of gingivitis and a subset assigned a power-brush. BOP and plaque scores were assessed at baseline and 3-months. RESULTS A total of 538 participants (369:169; intervention: control) completed the study. BOP reduced in both gingivitis groups with significantly greater reduction in intervention compared to control group (BOP:38% vs 19%, p = 0.0236); Borderline significance favouring the intervention was demonstrated for the low gingivitis group (BOP:37% vs 15%, p = 0.0523). A highly significant reduction in BOP (intervention vs control) was demonstrated for volunteers who swapped from manual to power-brush (44% vs 37%, p = 0.0039). Plaque score improved more in control than intervention group (Plaque:37% vs 44%, p = 0.00215). CONCLUSIONS Behaviour change techniques were readily mastered by the dental professional researchers. The introduction of an oral hygiene behaviour change intervention significantly reduced gingivitis in volunteer patients compared to control at 3 months. Swapping to a power-brush significantly favoured BOP reduction compared to manual brush continuation although plaque reduction did not follow expectation in comparison to BOP scores. Behaviour change techniques should routinely be considered in patient care. CLINICAL SIGNIFICANCE Plaque-induced gingivitis is highly prevalent in the UK despite being preventable with good oral hygiene. Its continuum, periodontitis, negative impacts quality of life. This study suggests oral hygiene behavioural interventions (GPS) significantly reduce gingivitis and that GPS introduction will improve oral health and may improve quality of life.

Abstract
OBJECTIVES To investigate the prevalence of true periodontal chief complaints (CC) and the factors affecting their reporting by patients with periodontal diseases (PD). MATERIALS AND METHODS This cross-sectional study was based on retrospective analysis of available periodontal records. Different personal and demographic variables were obtained from these records including CC, age, gender, working status, past medical/dental history, smoking status and diagnosis. In addition, clinical parameters of plaque index, gingival index, probing pocket depth (PPD), and number of missing teeth. Periodontal CC were retrieved and divided either into true periodontal (bleeding, tooth mobility, and alteration in gingival color/shape) or others (emergency and esthetic-related) CC. RESULTS A total of 1161 records were included in the final analysis. Results showed that only 287 (24.7%) of patients reported true periodontal CC whereas the remaining 874 (75.3%) patients were not aware about symptoms of PD. Regression modeling indicated that reporting of true CC was positively associated with smoking and PPD but negatively associated with number of missing teeth and gender (male). CONCLUSIONS Results suggested that recognition of true periodontal CC by the patients was low. Reporting of true periodontal CC was significantly associated with smoking, PPD, female and lower number of missing teeth. These results shed light on the importance of increasing public knowledge about PD which is essential to aid people in recognizing these diseases at early stages.

Abstract
BACKGROUND Discomfort encountered during oral processing may cause food avoidance and increase the risk of malnutrition in older adults. The aim of the present survey was to explore the relationships between oral health and the oral discomfort experienced while eating in senior people. MATERIALS AND METHODS In a cross-sectional study, oral discomfort was assessed in a sample of 119 independently living participants aged between 35 and 81 years. Statistical analyses were used to identify categorical variables associated with food-related oral discomfort, including age, oral health-related quality of life (OHQoL), saliva secretion, occluding support, oral diseases and denture use. RESULTS Food-related oral discomfort concerned 28.5% of the participants. Within the sample study, the risk of experiencing food-related oral discomfort was increased for participants perceiving average (OR = 7.968, CI 95% = 2.603-24.381, p = .000) or poor OHQoL (OR = 17.109, CI 95% = 4.398-66.552, p = .000) and presenting strictly fewer than 7 occlusal functional units (OFUs) (OR = 3.396, CI 95% = 1.206-9.561, p = .020). Textured foods including fibrous (66.6%), heterogenous (60.6%) and grainy foods (42.4%) were mostly cited as food-related oral discomfort trigger factors. Within the 66-80 years group, participants having 0-6 OFUs were four times more likely to experience oral discomfort related to fibrous foods than participants having more than 7 OFUs (OR = 4.812, CI 95% = 1.192-19.415, p = .024). Within this group, participants having their teeth replaced by denture were also four times more likely to develop oral discomfort related to foods with heterogeneous textures (OR = 4.714, CI 95% = 1.030-21.562, p = .045) and grainy foods (OR = 7.285, CI 95% = 1.308-40.568, p = .023) than non-denture wearers. CONCLUSION Poor oral health conditions may generate oral discomfort with foods in the elderly especially with fibrous, heterogenous and grainy textures, and thus affect mealtime experience.

Abstract
OBJECTIVE The purpose of this study was to clarify the relationship between bacteria-induced butyric acid and periodontal disease progression. DESIGN Normal human gingival fibroblasts were exposed to butyric acid (0, 1, 5, 10, and 15 mM) adjusted to a pH of 7.2-7.4 using sodium hydroxide for 0-96 h and cell viability was evaluated. In addition, the effects of butyric acid on the production of matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs) in gingival fibroblasts were analyzed by real-time RT-PCR, ELISA, western blotting, and stromelysin zymography. RESULTS Butyric acid reduced the viability of gingival fibroblasts in a concentration- and time-dependent manner. Furthermore, butyric acid promoted production of MMP-1, MMP-3, and MMP-10 in gingival fibroblasts and suppressed TIMP-2 protein production. CONCLUSIONS Butyric acid promoted overproduction of MMPs, resulting in a disruption of the balance between MMPs and TIMPs expression in gingival fibroblasts. Our study suggests that the butyric acid produced by causative bacteria stimulates excessive MMP expression in periodontal tissue, leading to destruction of the tissue.

Abstract
The use of probiotics, which can be administered in oro-dispersible films (ODFs) and have prolonged activity in the mouth, was explored. ODFs made of xylitol and containing Streptococcus salivarius were formulated using inkjet printing and tested against Streptococcus mutans - a causative organism of dental caries. The testing of the prepared ODFs involved co-incubating an ink-jetted formulation of S. salivarius and xylitol with S. mutans and monitoring the microbial growth kinetics in real-time using isothermal microcalorimetry and colony plate counts. Cell-free supernatants (CFS) of S. salivarius were also tested against S. mutans. The phosphate solubilisation potential of S. salivarius was also determined and found to be negative, an indication that the species will not deplete phosphate from teeth. From the tests, it was observed that the formulation reduced the S. mutans population from 7.9 to 5.04 Log CFU/mL post-calorimetry (approximately 3 Log reduction) which was comparable to the 99.9% reduction expected during antimicrobial activity testing. A gradual decrease in S. mutans population was also observed with increasing of CFS of S. salivarius volumes indicative of pathogen suppression. This study demonstrates that S. salivarius can be useful in managing dental caries and ODFs of S. salivarius can be formulated easily using ink-jetting for such management.

Abstract
OBJECTIVES The purpose of this preliminary study was to explore blood microcirculation and somatosensory profiles in periodontitis patients before and after non-surgical periodontal therapy. MATERIALS AND METHODS Twenty patients (10 men and 10 women, 20 to 30 years old) and 20 age- and gender-matched healthy controls were included. Non-surgical periodontal therapy was performed for all patients. Clinical examination including pocket probing depth (PPD), clinical attachment loss (CAL), and bleeding on probing (BOP) were performed at baseline (BL), 1 week (1W), and 4 weeks (4W) after non-surgical periodontal therapy on 6 sites of tooth 32 and 42. Laser Doppler flowmetry (LDF) and quantitative sensory testing (QST) were applied at the attached gingiva of tooth 32 and 42 at BL, 1W, and 4W after non-surgical periodontal therapy. Data were analyzed with a two-way mixed-model of ANOVA. RESULTS The PPD, CAL and BOP significantly improved after non-surgical periodontal therapy (p < 0.001). Periodontitis patients demonstrated a higher tissue microvascular blood cell concentration (p = 0.015) and a significant gain in thermal (p = 0.037) and mechanical (p = 0.003) somatosensory function compared to controls. After non-surgical periodontal therapy, the flux (p = 0.002) and speed (p = 0.008) of blood flow decreased significantly and thermal (p = 0.029) and mechanical (p < 0.001) somatosensory function were reversed. CONCLUSION Gingival microcirculation and somatosensory function seem impaired in patients with periodontitis and are reversed following non-surgical periodontal therapy. CLINICAL RELEVANCE LDF and QST may be appropriate tools to further characterize gingival inflammation and treatment responses in periodontitis.

Abstract
BACKGROUND The purpose of this prospective study was to compare the changes in periodontal somatosensory function and microcirculation in patients with periodontitis following initial treatment with scaling and root planing (SRP) with or without adjuvant laser therapy. METHODS Twenty-four patients suffering from periodontitis were recruited and randomly allocated into a split-mouth design to either SRP combined laser therapy side (test side) or SRP only side (control side). All treatments were performed by the same investigator at a single visit. Laser Doppler Flowmetry (LDF) and Quantitative Sensory Testing (QST) were performed at baseline (W0), 1 week (1W), 2 weeks (2W), and 4 weeks (4W) after treatment on both sides of the attached gingiva of the maxillary lateral incisor. Clinical examination including probing depth (PD) and bleeding on probing (BOP) was performed at W0, 2W, and 4W on both sides. Data were analyzed with two-way analysis of variance. RESULTS PD and BOP significantly improved after treatment (P <0.001). LDF values were significantly decreased on both sides at all follow-up time points (P <0.001), temperature was increased only on the test side (P = 0.017) whereas there was no significant change on the control side (P = 0.792). Significantly less sensitivity was observed for all QST parameters (P <0.030) except for warmth detection after treatment. CONCLUSION Adjunctive use of laser therapy did not provide any significant clinical advantage or additional effects on the recovery of periodontal somatosensory function or gingival microcirculation in the present study.

Abstract
Infection-induced chronic pain is an under-studied pain condition. One example is apical periodontitis, which evokes considerable mechanical allodynia that persists after treatment in 7% to 12% of patients. Available analgesics often provide incomplete relief. However, a preclinical model to study pain mechanisms associated with apical periodontitis is not available. Here, we report a mouse model of apical periodontitis to facilitate studies determining mechanisms mediating persistent infection-induced pain. Mice were anesthetized and the left first molar was exposed to the oral environment for six weeks. Bone resorption, as an indicator of apical periodontitis, was quantified using microcomputed tomography. Mechanical allodynia was determined using extraoral von-Frey filaments in both male and female mice. The expression of c-fos in the medullary dorsal horn was assessed using immunohistochemistry. Mice with apical periodontitis developed significant mechanical allodynia by day 7 that was maintained for 42 days. Mechanical thresholds were significantly lower in females compared to males. Administration of ibuprofen, morphine, or MK-801 reversed mechanical allodynia. Finally, apical periodontitis triggered an upregulation of c-fos in the medullary dorsal horn. Collectively, this model simulates signs of clinical pain experienced by patients with apical periodontitis, detects sex differences in allodynia, and permits the study of peripheral and central trigeminal pain mechanisms.

Abstract
BACKGROUND The first aim was to present descriptive data on the frequency of dental visits among older adults in Germany. The second aim was to identify the determinants of the number of dental visits using a longitudinal approach. METHODS Longitudinal data were derived from the German Ageing Survey, which is a nationally representative sample of community-dwelling individuals ≥40 years in Germany. The frequency of dental visits in the past 12 months was recorded in the years 2002, 2008 and 2011. In order to control for time-constant unobserved heterogeneity, Poisson fixed effects regressions were used. RESULTS While the mean number of dental visits was 2.3 (SD: 2.0) in 2002, it was 2.0 (SD: 1.7) in 2008 and 2.1 (SD: 1.7) in 2011. The frequency of dental visits declined with age (total sample and women), transitions from normal weight to overweight (total sample), changes from divorced/widowed/single/married, living separated from spouse to 'married, living together with spouse' in women and with a decrease in the number of physical illnesses (total sample and men). CONCLUSIONS The frequency of dental visits declines with age in older adults. While some of the determinants of frequency are non-modifiable (e.g., ageing and worsening of general health), others are modifiable (e.g., change in weight category).

Abstract
Purpose The purpose of this study was to evaluate the prognostic effect of patient compliance with supportive periodontal treatment (PC-SPT). Chronic periodontitis patients were classified based on their compliance level, and factors affecting PC-SPT and the prognosis of PC-SPT were investigated. Methods This study selected 206 patients who started SPT after receiving periodontal treatment between 2010 and 2012. Patients who continued SPT through February 2016 were included. The patients were classified according to whether they exhibited complete compliance (100% of visits), excellent compliance (≥70% of visits), incomplete compliance (<70% of visits), or non-compliance (only 2 visits). Patient characteristics that could affect PC-SPT, such as age, sex, distance of the clinic from their residence, implantation, and periodontal treatment, were investigated. The number of newly decayed and extracted teeth, alveolar bone level changes around the teeth and implants, and implant removal were examined to evaluate the prognosis of PC-SPT. Results Sex and the presence of an implant significantly affected PC-SPT. Additionally, the number of newly decayed and extracted teeth and changes in alveolar bone levels around the teeth and implants were significant prognostic factors related to PC-SPT. Conclusions PC-SPT in chronic periodontitis patients will help maintain periodontal health and prevent further periodontal disease.

Relationship between periodontal disease and butyric acid produced by periodontopathic bacteria. Inflamm Regen 2018; 38:23.

Abstract
Background Periodontopathic bacteria such as Porphyromonas gingivalis produce a large amount of butyric acid as a metabolite. Though butyric acid has been reported to have an anti-inflammatory effect on inflammatory diseases in the gastrointestinal tract, it has been suggested to contribute to the progression of periodontal disease in the oral cavity. The concentration of butyric acid in periodontal tissue of patients with periodontitis patients is reported to increase with the progress of the periodontal disease state. However, the influence of butyric acid on periodontal disease progression is not well known. Main text In this review, we have considered the relationship between butyric acid and periodontal disease with respect to the findings reported till date and the knowledge we newly obtained [Shirasugi M et al. Biochem Biophys Res Commun, 2017]. We have studied the relationship between butyric acid and periodontal disease by analyzing the effect of butyric acid on normal human gingival fibroblasts, which are a major component of periodontal tissue. We observed that gingival fibroblasts underwent cytostasis and apoptosis via extrinsic and intrinsic pathways upon long-term exposure to butyric acid. In addition, we showed that TNF-α produced by gingival fibroblasts treated with butyric acid plays an important role in inducing exogenous apoptosis. Conclusion Butyric acid produced by periodontopathic bacteria may promote progress of the periodontal disease state. Butyric acid is known to act as an HDAC inhibitor. Thus, we believe that advanced epigenetic analysis of the effects of butyric acid on gingival fibroblasts will help elucidate the periodontal disease pathology and facilitate discovery of new targets for periodontal disease treatment.

Abstract
BACKGROUND The purpose of this study was to evaluate the psychometric properties of the validated Spanish version of the Illness Perception Questionnaire Revised for Oral Health (IPQ-R-OH) in patients with periodontal disease. METHODS We used the IPQ-R-OH, a 36-item self-report scale. This study was carried out using data from 517 patients with periodontal disease attending the dental clinic at the Universidad Cooperativa de Colombia, Pasto, Colombia. A three-parameter logistic model (3PL) for polytomous response was calculated to evaluate a model of individuals' responses. The McDonald's Omega (Ω ≥ 0.60) coefficient and composite reliability were used to determine the internal consistency. Confirmatory factor analysis (CFA) was conducted to examine the fit of the hypothesized seven-factor model, and the configural invariance was tested to estimate the structure in each sex group. RESULTS The slope, location, and guessing parameters determined reasonable accurate items according to item response theory analysis. The internal consistency coefficients of each factor ranged from 0.62 to 0.93 (McDonald's Omega) and 0.66 to 0.87 (composite reliability). Confirmatory factor analysis indicated a seven-factor model (χ2 S-B = 2572.165; χ2 S-B /(573) = 4.489, P < 0.01; non-normed fit index = 0.950; CFI = 0.950; root means square error of approximation = 0.055 (90% confidence interval [0.052 - 0.059]); standardized root mean residual = 0.080 and Akaike information criteria = 1426.165. The seven factors loaded similarly to the original IPQ-R scale. Multigroup CFA analysis results supported factor invariance across the sex groups. CONCLUSION These findings suggest that the IPQ-R-OH has adequate reliability and construct factorial validity; therefore, it could be a valuable instrument in screening illness perceptions in patients with periodontal disease.

Abstract
Introduction: Orofacial pain of periodontal origin has a wide range of causes, and its high prevalence and negative effect on patients' quality of life make intervention mandatory. This review provides a periodontological overview of the field of orofacial pain, focusing on the entities which involve the periodontal tissues and may be the cause of this pain or discomfort. Methods: The study comprised a literature search of these pathologies conducted in the MEDLINE/PubMed Database. Acute infectious entities such as gingival and periodontal abscesses are emergencies that require a rapid response. Periodontitis associated with endodontic processes, necrotizing periodontal disorders, desquamative gingivitis, gingival recession, and mucogingival herpetic lesions, cause mild to severe pain due to tissue destruction and loss. Other lesions that lead to periodontal discomfort include gingival enlargement and periodontal ligament strains associated with occlusal trauma, parafunctional habit and the impaction of food or foreign bodies. Conclusion: A range of therapeutic, pharmacological and surgical alternatives are available for the management of these injuries. However, the wide variety of causes of orofacial pain or periodontal discomfort may confuse the clinician during diagnosis and may lead to the wrong choice of treatment.

Abstract
Background Periodontitis is an inflammatory disease accompanied by alveolar bone loss and progressive inflammation without pain. However, the potential contributors eliminating pain associated with gingival inflammation are unknown. Results we examined the involvement of CXC chemokine receptor type 4 (CXCR4) on the mechanical sensitivity of inflamed periodontal tissue, using a mouse model of periodontitis established by the ligation of the tooth cervix of a maxillary second molar and inoculation with Porphyromonas gingivalis (P. gingivalis). Infiltration of inflammatory cells into gingival tissue was not observed following the inoculation. Under light anesthesia, the mechanical head withdrawal threshold (MHWT) on the buccal gingiva was measured using an electronic von Frey anesthesiometer. No significant changes in MHWT were observed in the mice with P. gingivalis-induced periodontitis during the experimental period. Continuous administration of CXCR4 neutralizing antibody to the gingival tissue significantly decreased MHWT and increased the number of gingival CXCR4 immunoreactive macrophages in the periodontitis group. Nitric oxide metabolites in the gingival tissue were significantly increased after the inoculation of P. gingivalis and were reduced by gingival CXCR4 neutralization. Gingival L-arginine administration induced gingival mechanical allodynia in naive animals. Moreover, the decrease in MHWT after treatment with P. gingivalis and CXCR4 neutralization was partially reversed by nitric oxide synthase inhibition in the gingival tissue. Nuclear factor-kappa B was expressed in infiltrating macrophages after inoculation of P. gingivalis and administration of the nuclear factor-kappa B activator betulinic acid induced gingival mechanical allodynia in naive mice. Conclusions These findings suggest that CXCR4 signaling inhibits nitric oxide release from infiltrating macrophages and is involved in modulation of the mechanical sensitivity in the periodontal tissue in P. gingivalis-induced periodontitis.

Abstract
The causes of periodontal disease are complex. Butyric acid, a metabolite of periodontopathic bacteria such as Porphyromonas gingivalis, acts as a histone deacetylase inhibitor that has a direct effect on mRNA expression. Butyric acid produced by Clostridium butyricum in the intestinal tract induces differentiation of regulatory T cells, thereby suppressing inflammation in the gut. Mice lacking Clostridium butyricum in the intestinal tract suffer from colitis. By contrast, butyric acid in the oral cavity worsens periodontal disease. Periodontal disease is a chronic condition in which periodontal tissue is exposed to virulence factors (such as butyric acid); however, no study has examined the effects of long-term exposure to butyric acid. The present study demonstrated that long-term exposure of human gingival fibroblasts (HGFs) to butyric acid induced cytostasis and apoptosis via the intrinsic and extrinsic pathways. Butyric acid inhibited the division of HGFs by altering expression of mRNAs encoding cyclins. Butyric acid induced apoptosis in HGFs via the intrinsic pathway, followed by activation of caspase 9; there was no DNA damage or p53 activation. Butyric acid also upregulated expression of TNF-α mRNA and protein by HGFs. Furthermore TNF-α induced apoptosis by activating caspase 8 (the extrinsic pathway) and by inducing production of pro-inflammatory cytokines. Taken together, the results show that butyric acid induced cytostasis and apoptosis in HGFs, accompanied by production of pro-inflammatory cytokines. It thus acts as a death ligand and plays a critical role as a prophlogistic substance.
