Abstract
Periodontal disease (PD), a chronic inflammatory disorder that damages the tooth and its supporting components, is a common global oral health problem. Understanding the intricacies of these disorders, from gingivitis to severe PD, is critical for efficient treatment, diagnosis, and prevention in dental care. Periodontal biosensors and biomarkers are critical in improving oral health diagnostic skills. Clinicians may accomplish early identification, tailored therapy, and efficient tracking of periodontal diseases by using these technologies, ushering in a new age of accurate oral healthcare. Traditional periodontitis diagnostic methods frequently rely on physical probing and visual examinations, necessitating the development of point-of-care (POC) devices. As periodontal disorders necessitate more precise and rapid diagnosis, incorporating novel innovations in biosensors and biomarkers becomes increasingly crucial. These innovations improve our capacity to diagnose, monitor, and adapt periodontal therapies, bringing in the next phase of customized and effective dental healthcare. The review discusses the characteristics and stages of PD, clinical treatment techniques, prominent biomarkers and infection-associated factors that may be employed to determine PD, biomedical sensing, and POC appliances that have been created so far to diagnose stages of PD and its progression profile, as well as predicting future developments in this field.

Blood count, endocrine, immunologic, renal, and hepatic markers in a case-control animal study of induced periodontitis in female rodents. Front Physiol 2024; 15:1327399. [PMID: 38444766 PMCID: PMC10912185 DOI: 10.3389/fphys.2024.1327399] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Accepted: 01/31/2024] [Indexed: 03/07/2024] Open
Abstract
Introduction: Periodontitis is a non-communicable chronic inflammatory disease with a systemic burden. Animal models of induced periodontitis help elucidate the mechanisms by which periodontal inflammation drives systemic effects. Studying this systemic involvement over longer follow-up periods may provide a strong foundation for future research on the association between diseases and periodontitis, particularly in female rats. Therefore, we aimed to compare blood, endocrine, immunologic, renal, and hepatic markers in a rat model of induced periodontitis in females with their control counterparts. Methods: Experimental periodontitis was induced in 20 female Wistar rats by the application and maintenance of silk ligatures on the upper molars. The rats were then assessed for macroscopical analysis, complete blood count, and biochemical, endocrine, and immunologic markers at 21, 28, 42, and 56 days. Results: Chronic periodontal inflammation was observed after 42 days of exposure to the ligatures. Additionally, it was also possible to notice significant systemic manifestations, such as the reduction of triiodothyronine and thyroxine levels, along with an increase in the expression of alkaline phosphatase, gamma-glutamyl transpeptidase, and lactate dehydrogenase. Discussion: The study's findings imply that certain changes can be underscored to highlight a reduced risk of conception. Notably, previous investigations have indicated that subfertile women exhibit lower levels of thyroid hormones and elevated lactate dehydrogenase expression. Despite the absence of preclinical data delineating a possible association between periodontitis and female infertility, the results of this study may prove to be a crucial contribution to both the scientific and medical fields.

Abstract
BACKGROUND The spectral dual-mode response towards analyte has been attracted much attention, benefiting from the higher detection accuracy of such strategy in comparison to single signal readout. However, the currently reported dual-mode sensors for acid phosphatase (ACP) activity are still limited, and most of them more or less exist some deficiencies, such as complicated construction procedure, high-cost, poor biocompatibility, aggregation-caused quenching and limited emission capacity. RESULTS Herein, we employed Fe3+ functionalized CuInS2/ZnS quantum dots (CIS/ZnS QDs) as nanosensor to develop a novel fluorometric and colorimetric dual-mode assay for ACP activity, combing with ACP-triggered hydrolysis of ascorbic acid 2-phosphate (AAP) into ascorbic acid (AA). The Fe3+ binding to CIS/ZnS QDs can be reduced into Fe2+ during the determination, resulting in the dramatically weakened photoinduced electron transfer (PET) effect and the disappearance of competition absorption. Thus, a highly sensitive ACP assay in the range of 0.22-12.5 U L-1 through fluorescence "turn-on" mode has been achieved with a detection of limit (LOD) of 0.064 U L-1. Meanwhile, the ACP activity can also be quantified by spectrophotometry based on the chromogenic reaction of the formed Fe2+ with 1,10-phenanthroline (Phen). Moreover, the designed nanosensor with good biocompatibility was successfully applied to image and monitor the ACP levels in living cells. SIGNIFICANCE We believe that the proposed method has remarkable advantages and potential application for ACP assay in terms of the high accuracy, simplicity, low cost, as well as its adequate sensitivity.

Abstract
This study aimed to determine the effect of local application of curcumin gels as adjunct to scaling and root planing (SRP) on the inflammatory biomarkers matrix metalloproteinase-8 (MMP-8), interleukin-6 (IL-6), C-reactive protein (CRP), and alkaline phosphatase (ALP), and the anti-inflammatory biomarker interleukin-10 (IL-10) in rats with experimentally induced periodontitis. Fifty-five adult Wistar rats with experimentally induced periodontitis were randomly divided into four groups: 15 rats received SRP + curcumin gel (CU), 15 rats received SRP + Tetracycline gel (Tet), 15 rats were treated with SRP alone, and 5 rats had experimental periodontitis without treatment (EP). Five systemically healthy rats without experimental periodontitis were used as the controls. Blood samples were collected by cardiac puncture from all groups after 2, 4, and 6 weeks of therapy. Biomarker levels determined by enzyme-linked immunosorbent assay (ELISA) and, ANOVA were used to compare the study groups. The results showed a significant increase in pro-inflammatory biomarkers and a significant decrease in anti-inflammatory biomarkers in the EP group compared with the control group (p < 0.05). The local application of curcumin or tetracycline gels resulted in a significant reduction in all inflammatory biomarkers at all periods of examination compared to the EP group. IL-10 levels gradually increased after 2 weeks, peaked at 4 weeks, and then decreased after 6 weeks, however, Tet showed statistically significant improvement compared to CU (p < 0.05). Adjunctive application of CU gel was as effective as Tet gel in the treatment of EP in rats by reducing inflammatory biomarkers and enhancing anti-inflammatory cytokines.

Abstract
Periodontitis (PD) is a severe inflammatory gum pathology that damages the periodontal soft tissue and bone. It is highly prevalent in the US, affecting more than 47% of adults. Besides routine scaling and root planing, there are few effective treatments for PD. Developed as an effective treatment for hyperlipidemia, simvastatin (SIM) is also known for its well-established anti-inflammatory and osteogenic properties, suggesting its potential utility in treating PD. Its clinical translation, however, has been impeded by its poor water-solubility, lack of osteotropicity, and side effects (e.g., hepatoxicity) associated with systemic exposure. To address these challenges, an N-(2-hydroxypropyl) methacrylamide (HPMA) copolymer-based thermoresponsive polymeric prodrug of SIM (ProGel-SIM) was developed as a local therapy for PD. Its aqueous solution is free-flowing at 4 °C and transitions into a hydrogel at ∼30 °C, allowing for easy local application and retention. After a thorough characterization of its physicochemical properties, ProGel-SIM was administered weekly into the periodontal pocket of an experimental rat model of PD. At 3 weeks post initiation of the treatment, the animals were euthanized with palate isolated for μ-CT and histological analyses. When compared to dose equivalent simvastatin acid (SMA, active form of SIM) treatment, the rats in the ProGel-SIM treated group showed significantly higher periodontal bone volume (0.34 mm3 vs 0.20 mm3, P = 0.0161) and less neutrophil (PMN) infiltration (P < 0.0001) and IL-1β secretion (P = 0.0036). No measurable side effect was observed. Collectively, these results suggest that ProGel-SIM may be developed as a promising drug candidate for the effective clinical treatment of PD.

Abstract
Background Neutrophils continuously migrate into the oral cavity from various sources like gingival crevicular fluid and saliva both in health and in inflammation. The migration of the neutrophils into the various tissues and into the oral cavity occurs when the host microbial interplay tips the balance favoring the initiation of the inflammatory and immune reactions which depending on the amount of the microbial load results in the development of acute and chronic infections in the susceptible host. Aim The present study was designed to quantify and compare the oral salivary neutrophil levels in patients with gingivitis and chronic and aggressive periodontitis as well as in healthy controls, before and after scaling and root planing (SRP) and to compare the difference within the selected study groups. Materials and Methods Forty subjects were classified into four groups, that is, healthy controls, gingivitis, and chronic and aggressive periodontitis. Oral rinse samples were collected using Hank's balanced salt solution from each patient before and after phase I periodontal therapy. Cells in the rinse samples were stained with Acridine orange, and neutrophil counts were carried out using a fluorescence microscope and a hemocytometer. Results Baseline oral salivary neutrophil levels were maximum in the chronic periodontitis group followed by the aggressive group and then the gingivitis group. Oral salivary neutrophil levels also positively correlated to probing pocket depth, plaque index, calculus index, and gingival index in all four study groups. Maximum reduction in the oral salivary neutrophil levels after phase I periodontal therapy was seen in the gingivitis group. Conclusion From our study, we conclude that the oral salivary neutrophil levels decreased significantly after SRP. Estimation of changes in the oral salivary neutrophil levels has the potential to aid in monitoring treatment outcomes. Thus, it suggests that it could be used as a simple, noninvasive laboratory technique to monitor the periodontal status and disease progression.

Abstract
Personalized Oral Healthcare has recently become the new trend word in medicine and dentistry. In this context, saliva diagnostics using various biomarkers seem to be the gateway to personalized dental diagnostics and therapy. But the terminology is not (yet) uniformly defined, furthermore it is unclear to what extent which salivary markers play a relevant role in the therapeutic decision making. In this Scoping Review, an electronic search was conducted in PubMed and Web of Science databases using medical subject headings (MESH terms) “saliva”, “biomarker”, “personality/persons”, and “dentistry”. Only human studies were included, in which repeated salivary measurements were performed to analyze monitoring effects with at least ten patients per group. PRISMA-ScR and Tricco guidelines were followed: (i) to examine what salivary biomarkers have been explored in terms of personalized oral healthcare and precision dentistry, (ii) to investigate the clinical relevance for oral health and its correlation to systemic health, and (iii) to summarize an outlook for future developments based on these results. Out of 899 studies, a total of 57 were included for data extraction in this Scoping Review, mainly focusing on periodontal therapy and patient monitoring. Salivary biomarkers have shown the potential to change the field of dentistry in all dental disciplines as a key for personalized workflows. The increasing interest in dental research is obvious, demonstrated by the growing number of publications in recent years. At this time, however, the predominant discipline is periodontology, which allows biomarker-based monitoring of the disease prevention and progression. The studies included showed heterogeneous methods using manifolds biomarkers. Therefore, no uniformly accepted concept can be presented today. Further clinical research with well-defined outcomes including standardized procedures is necessary.

Correlation of Blood and Salivary pH Levels in Healthy, Gingivitis, and Periodontitis Patients before and after Non-Surgical Periodontal Therapy. Diagnostics (Basel) 2022; 12:diagnostics12010097. [PMID: 35054264 PMCID: PMC8774853 DOI: 10.3390/diagnostics12010097] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 12/21/2021] [Accepted: 12/27/2021] [Indexed: 11/17/2022] Open
Abstract
Periodontitis is an infectious illness which leads to the inflammation of protective tissues around the teeth and the continuous loss of alveolar bone and conjunctive tissue. Biomarker analysis in serum and saliva helps in the evaluation of disease progression and activity. It is also established that every inflammatory change along with resultant damage of tissues ends up in altered pH values in the fluids and tissues. Aim: To correlate the connection of pH levels in both blood as well as saliva in healthy, periodontitis, and gingivitis patients. Materials and Methods: The current research involved 145 subjects amidst the age of 20 and 55 years. The subjects were split into three different groups: healthy (Group A), gingivitis (Group B), and finally chronic periodontitis (Group C). The recording of clinical parameters was done by gingival index (GI), probing depth (PD), and plaque index (PI). pH of saliva and blood was analyzed with the help of digital single electrode pH meter. Subjects have gone through scaling and root planning (SRP) coupled with the instructions of oral hygiene. They were recalled post 4 weeks, and saliva and blood samples were gathered for analyzing pH. Results: Clinical parameters GI and PI were statistically important in both group C as well as group B post SRP. A crucial change has been observed in attachment levels (AL) and PD in the case of periodontitis group post SRP. The difference in the salivary pH values were significant between group B vs. C and A vs. C before the treatment because the values for group C were acidic, whereas in groups B and A the pH was alkaline. After the treatment, the values were still significant because the pH has become more alkaline compared to preoperative value in both group B and C. Saliva’s pH levels have demonstrated a statistically significant reduction in group C post SRP. Conclusion: Salivary pH levels and blood evidently became alkaline in the group C patients post SRP and there is a positive correlation between them and the clinical parameters.

Abstract
Aim of the study: The aim of this study is to determine the values of salivary enzyme biomarkers (alkaline phosphatase - ALP, aspartate aminotransferase - AST and lactate dehydrogenase - LDH) in subjects with healthy and diseased periodontium and to investigate the possibility of using these salivary enzymes as diagnostic and prognostic markers. Methods: We collected saliva with the spitting method from all examinees in the morning, using the recommendations provided by Navazesh. The values of the enzymes in saliva were determined spectro-photometrically, with the following methods: ALP-IFCC, AST-IFCC, LDH-PYRUVATE. IGI Silness-Löe was used to determine the presence of gingival inflammation, and to determine the presence of clinically manifest periodontitis, we determined the clinical loss of periodontal attachment with a graduated periodontal probe. For statistical purposes, we used the method of ANOVA Chi Square and Student's t-test. Results: The difference in the average salivary AST and LDH values between the first and the second group, as well between the first and third group is statistically significant (p < 0.000). The difference in the average salivary AST and LDH values between the examinees with gingivitis and the examinees with clinically manifest periodontal disease is statistically insignificant (p < 0.485101 for AST, p < 0.816665 for LDH). The difference in the average salivary levels of ALP between the three groups is statistically significant (p < 0.000). Conclusion: The salivary levels of AST, LDH, and ALP can be used as diagnostic markers, while ALP can also be used as a prognostic marker for periodontal disease.

Abstract
Background:
Menopause is a physiological phenomenon that occurs in aging women. Periodontal disease is associated with menopausal status. Alkaline phosphatase (ALP) plays a role in general and periodontal bone turnover. Calcium is essential for the maintenance of bone and teeth, and serum ALP and calcium are specific bone markers related to the acceleration of bone mass loss in elderly women and periodontitis.
Objectives:
The aim of this study was to correlate the levels of serum ALP and calcium with periodontal status in perimenopausal and postmenopausal women with periodontitis.
Methods:
A total of 22 perimenopausal and 49 postmenopausal women underwent a full periodontal examination assessing the pocket depth, number of teeth lost, clinical attachment loss, plaque index, calculus index, and papillary bleeding index. Using these measurements, the subjects were divided according to periodontal severity. Serum ALP and calcium were measured using the Enzyme-Linked Immunosorbent Assay (ELISA) method. A correlation between serum ALP and calcium to periodontal status was investigated.
Results:
Serum ALP was significantly correlated with the severity of periodontitis, clinical attachment loss, and the number of teeth lost among perimenopausal and postmenopausal women (p < 0.05). Serum calcium levels were not correlated with periodontal status.
Conclusion:
Postmenopausal women tended to have more periodontal breakdown, and the level of serum ALP was increased in severe periodontitis.

Abstract
The aim of this study was to assess the changes in vital salivary parameters such as calcium, phosphorous, alkaline phosphatase, buffering capacity, pH, flow-rate and Oral Hygiene Index (OHI) in fixed orthodontic treatment patients during the retention period. In this study, saliva samples were collected from 35 patients before de-bonding (T0) and after 4 to 5 weeks of de-bonding or on retention period (T1). The biochemical parameters such as calcium, phosphorous and alkaline phosphatase levels were measured with saliva samples. Additionally, flow-rate, buffering capacity, pH and OHI levels was also measured. The current study results showed reduction in calcium, alkaline phosphatase, pH, flow-rate and OHI levels during T1 (p < 0.05). However, phosphorous and buffering capacity levels were increased at T1. The phosphorous levels showed non statistically significant difference when compared between T0 and T1 (p = 0.42). The remaining salivary parameters showed statistically significant difference when compared between T0 and T1 (p < 0.05). The present study concludes that there was a statistically significant decrease in the calcium, alkaline phosphatase, pH, flow rate and OHI values a month after de-bonding and increased in the buffering capacity values.

The single signal amplification strategy is significant for detecting various disease biomarkers but is restricted by its limited accuracy. The multi-signal and multi-mode methods have overcome this deficiency. Acid phosphatase (ACP) is an important intracellular enzyme but one-step cell imaging material-based probes are scarce for ACP. Herein, we designed a one-step self-assembled polymer probe using neutral red (NR), modified-(pyridoxal-5'-phosphate (PLP)) and Eu3+. The polymer exhibited non-emission and excellent stability. Upon the catalytic hydrolysis reaction of ACP, the polymer exhibited two strong fluorescence signals at 373 nm and 613 nm and an appreciable decline of absorbance at 395 nm. The probe has excellent selectivity and higher sensitivity with a limit of detection as low as 0.02 mU mL-1. It possesses favorable biocompatibility and has been successfully used to detect and image intracellular ACP in several living cells.
