NCT07472218
This study aims to evaluate and compare the efficacy of two different eugenol-free periodontal dressing materials-Ora-Aid (a hydrophilic polymer) and Coe-Pak (a zinc oxide-based paste)-following non-surgical periodontal treatment (scaling and root planing, SRP) in patients with Stage 3, Grade A periodontitis. The study utilizes a split-mouth design to analyze clinical periodontal parameters, patient comfort, and microbiological changes over a 3-month period.
NCT07466966
This multicenter, single-masked randomized controlled clinical trial evaluates the effectiveness of minimally-invasive non-surgical therapy (MINST) compared with standard non-surgical peri-implant therapy (NSPT) in patients diagnosed with peri-implantitis. The study investigates clinical outcomes, radiographic bone levels, patient-reported outcomes, and treatment time over 12 months.
NCT07438184
This randomized controlled clinical trial evaluates the impact of non-surgical periodontal therapy on systemic inflammatory markers in patients with chronic prostatitis or recurrent urinary tract infections. Emerging evidence suggests a possible association between periodontal inflammation and genitourinary conditions. A total of 60 male participants diagnosed with periodontitis and either chronic prostatitis or recurrent urinary tract infections were randomly assigned to one of three groups: non-surgical periodontal therapy, oral hygiene instruction only, or no periodontal treatment. The primary outcomes were changes in serum prostate-specific antigen (PSA) levels and the frequency of positive urine cultures over a 120-day follow-up period. The study aims to investigate whether periodontal treatment may reduce systemic inflammatory burden and improve genitourinary clinical parameters.
NCT06734559
In teeth that remain decayed for a long time, the muscles in that area atrophy because the patient cannot use the decayed area much. As a result, muscle length and mass decrease. To compare the amount of this reduction before and after treatment with ultrasound and to treat accordingly
NCT06129643
The aim of this study is to evaluate in vivo the post operative pain after laser root canal treatment in necrotic teeth in an evidence-based clinical trial. The null hypothesis being tested is that there is no difference in post operative pain between conventional irrigation and the two types of lasers used. Forty-five patients are equally divided into 3 separate groups : * Group A (Conventional): 2.5% NaOCL and 17% EDTA. * Group B(Dual): saline along with Er,Cr:YSGG laser and diode laser combination * Group C(Combined): saline along with 17% EDTA and diode laser combination Each patient is given pain scale chart Numeric Rating Scale (NRS) to record his/her pain level before any endodontic treatment. All data will be collected, tabulated, summarized, and statistically analyzed.
NCT07297836
When faced with primary teeth affected by irreversible pulpitis or pulp necrosis, extraction is often the preferred option for practitioners, although validated alternatives exist, notably pulpectomy, which has high success rates when performed correctly. Recommended by the American Academy of Pediatric Dentistry, this technique relies on rigorous disinfection and the use of materials adapted to natural exfoliation. Lesion sterilization tissue repair (LSTR), although more controversial due to the use of topical antibiotics, can also be considered in certain clinical situations. However, data on French practices in this area are very limited, hence the need to evaluate practitioners' treatment choices, their potential reservations, and the criteria guiding their decisions.
NCT06426550
The aim of this clinical trial is to evaluate photodynamic therapy and photobiomodulation in the periodontitis treatment. To evaluate the clinical and microbiological response of conventional periodontal treatment associated with photodynamic therapy and photobiomodulation with red or infrared laser. Participants will receive periodontal treatment carried out with the use 0.005% methylene blue and laser therapy (photodynamic therapy), associated with conventional periodontal treatment, as well as the use of photobiomodulation with red or infrared laser associated with conventional periodontal treatment in participants with periodontitis. So, twenty periodontitis patients will be selected and separated in two groups compared with placebo. Clinical and microbiological parameters will be evaluated at baseline and 3 months after periodontal treatment: plaque Index, bleeding on probe, probing depth, gingival recession and clinical attachment level.
NCT07424846
The ground-breaking Prevention of Prematurity and Xylitol (PPaX) cluster randomized controlled clinical trial was conducted in Lilongwe, Malawi and enrolled approximately 10,069 pregnant individuals seeking to evaluate the impact of xylitol-containing chewing gum compared to no chewing gum on reducing the occurrence of maternal periodontal disease, preterm birth, and low birthweight offspring. The premise of this study centers upon the numerous publications supporting a strong association between maternal periodontal disease and preterm birth. Given that xylitol-containing chewing gum is considered a prebiotic and known to reduce cariogenic and periodontopathic bacteria, the study evaluated and discovered a statistically significant reduction in maternal periodontal disease, preterm birth, and low birthweight offspring among pregnant individuals who chewed xylitol-containing chewing gum. While PPaX demonstrated the efficacy of xylitol to reduce preterm birth (PTB), the study had important limitations: (a) PPaX was an unblinded cluster-randomized study with only 8 clusters, 4 with xylitol-containing chewing gum and 4 without any gum (not placebo-controlled); (b) PPaX used a suboptimal dose of 2 grams of xylitol daily which may have reduced the effectiveness of the intervention given that recent literature suggests 5-10 grams/day more effectively improve oral health; and (c) PPaX did not evaluate infant mortality nor early neurodevelopmental outcomes. Notably, reducing fetal exposure to periodontal disease (PD) as well as PTB may improve neurodevelopmental outcomes for offspring as both prematurity and fetal exposure to inflammation are well-documented risk factors for neurodevelopmental delay (NDD) and infant mortality. The investigators will conduct a double-blind, placebo-controlled, individually randomized clinical trial with 3 arms among Malawian pregnant individuals (n=6000) at \<20 weeks of pregnancy with the co-primary outcomes being the incidence of PTB and low birthweight offspring. The 3 study arms (n=2000 each) will be (a) an optimized dose of xylitol-containing chewing gum (6.4 grams/day), (b) the PPaX trial xylitol dose (2.1 grams/day), or (c) flavored sorbitol gum base (placebo control). This trial overcomes the PPaX trial's limitations and will definitively answer whether xylitol prevents PTB in Malawi. The investigators will additionally collect biospecimens from a random sampling of the participants for biobanking for later analysis of inflammatory and microbiome alterations that may occur with xylitol exposure compared with placebo. The investigators hypothesize that pregnant individuals who chew xylitol-containing chewing gum will have a significant reduction in periodontal disease metrics at 28-30 weeks' gestation (e.g. bleeding on probing) as well as offspring with improved neurodevelopmental outcomes as assessed by the Bayley Scales of Infant and Toddler Development 4th edition and reduced risk of adverse pregnancy outcomes including preterm birth.
NCT07423663
It is tackling antimicrobial resistance in endodontics, specifically comparing different intracanal medications used in root canal treatment. Given the growing concern over resistant bacterial strains, our study aims to evaluate the effectiveness of various medicaments in eliminating endodontic pathogens while minimising the risk of resistance development. By integrating microbiological analysis and clinical relevance, our research seeks to provide evidence-based recommendations for optimising intracanal disinfection protocols and improving treatment outcomes in endodontic infections.
NCT07418840
Background: Pulpitis and apical periodontitis are inflammatory conditions of the dental pulp and periapical tissues, primarily caused by microbial invasion. The global prevalence of pulpitis is considered high but underestimated, as up to 40% of cases are asymptomatic. Similarly, the prevalence of apical periodontitis varies widely (16-86%) depending on population characteristics, systemic conditions, and socioeconomic status, and it is reported to be higher in hospital settings. Endodontic therapy aims to disinfect and seal the root canal system, promoting healing of apical periodontitis or maintaining periapical health. Reported success rates for primary and non-surgical retreatment procedures are comparable (75% and 77%, respectively), though outcomes tend to be more favorable in vital teeth compared to those with apical periodontitis (84% vs. 75%). Despite the widespread use of endodontic therapy, few studies have assessed treatment outcomes in a hospital setting. Objectives: The primary aim of this prospective study is to evaluate the success of primary and non-surgical endodontic retreatments performed in a hospital environment. Secondary objectives include assessing (1) the survival of treated teeth, (2) patient-related outcomes (PROs), and (3) the influence of systemic diseases or ongoing therapies on treatment outcomes. Methods: This is a monocentric, prospective, observational, study to be conducted at the Dental Clinic of the A. Gemelli University Hospital, Rome. Adult patients (\>18 years) requiring primary or non-surgical endodontic retreatment due to symptomatic or asymptomatic irreversible pulpitis, apical periodontitis, or acute/chronic abscesses will be enrolled after providing written informed consent in accordance with the Declaration of Helsinki. Exclusion criteria include inability to complete follow-up, vertical root fractures, advanced periodontal disease requiring extraction, pregnancy or breastfeeding, and inability to provide informed consent. Patients will undergo standard endodontic therapy according to the European Society of Endodontology (ESE) guidelines. Clinical and radiographic evaluations will be performed preoperatively, intraoperatively, and postoperatively. Radiographic assessments will be based on the Periapical Index (PAI), and follow-ups will occur at 6 months, 1 year, and annually for up to 4 years, with a final clinical follow-up at 5 years. Patient-related outcomes will be evaluated using the Numerical Rating Scale (NRS-12) for pain and the Oral Health Impact Profile (OHIP-14) questionnaire before treatment and at 1, 3, and 7 days post-treatment. Outcome Measures: The primary endpoint is the rate of endodontic success, defined by the absence of clinical symptoms (pain, swelling, sinus tract, tenderness) and radiographic healing or maintenance of periapical health (Periapical Apex Index, PAI). Secondary endpoints include the incidence of postoperative complications, survival rate of treated teeth, associations between systemic conditions and endodontic outcomes, and patient-reported outcome measures. Statistical Analysis: The sample size was calculated according to Lachin et al., assuming an expected success rate of 85%, a 5% margin of error, and 90% power, resulting in a minimum of 74 patients. Qualitative variables will be expressed as frequencies and percentages, while quantitative variables will be summarized as mean ± SD or median, depending on distribution. Normality will be tested with the Kolmogorov-Smirnov test. Associations between categorical variables will be evaluated using Pearson's χ² or Fisher's exact test, and continuous variables with Student's t-test, Mann-Whitney U, ANOVA, or Kruskal-Wallis tests as appropriate. Repeated measures ANOVA or Friedman tests will be applied to detect longitudinal changes. Mixed-effects models ((G)LMM) will be used to analyze changes in PAI, NRS-12, and OHIP-14 over time while adjusting for confounders. Logistic regression will identify independent predictors of success, and Kaplan-Meier survival curves (log-rank test) will estimate tooth survival over follow-up. Significance will be set at p \< 0.05. Statistical analyses will be performed using IBM SPSS Statistics v25.0 (IBM Corp., Armonk, NY, USA). Expected Results and Conclusions: This study is expected to provide data on the clinical and radiographic success rates of primary and non-surgical endodontic treatments performed in a hospital setting. It will also clarify the impact of systemic diseases and patient-related factors on treatment outcomes. The findings may help optimize clinical protocols and patient management strategies in hospital-based endodontic care, contributing to evidence-based improvement of dental services and patient quality of life.
NCT07363135
The study aims to investigate whether application of albumin platelet-rich fibrin (Alb-PRF) into the gum pockets after scaling and root planing (SRP) can improve healing in patients with Stage III Grade B periodontitis. Periodontitis is a chronic disease that damages the tissues and bone surrounding the teeth and can lead to tooth loosening or loss if untreated. SRP is the first and most important treatment step, cleaning the tooth surfaces and smoothing the roots to reduce inflammation, but healing is often limited. PRF, made from the patient's own blood, is rich in platelets and growth factors that support tissue repair, and Alb-PRF is a new form that stays longer in the pocket and releases growth factors over time. In this study, 23 patients who meet the inclusion criteria (adults without systemic diseases, not using medications, non-smokers, not pregnant or breastfeeding, and not recently treated for periodontitis) will participate in a split-mouth design, where one side of the mouth receives SRP+ Alb-PRF and the other side receives SRP alone. Clinical measurements, including plaque, gum inflammation, bleeding, pocket depth, gum recession, and attachment levels, will be taken at baseline, 3 months, and 6 months, while X-rays will assess bone defects at baseline and 6 months. Additionally, gingival crevicular fluid (GCF) will be collected from the deepest pockets at baseline and on days 7, 14, and 21 to measure growth factors in the laboratory. Blood from patients will be processed to prepare the albumin-PRF gel, which will be carefully applied to the deep pockets on the test side. The investigators expect that pockets treated with albumin-PRF gel will show greater clinical attachment gain and higher, longer-lasting growth factor levels, potentially leading to improved gum and bone healing compared to SRP alone.
NCT07412431
This study aims to evaluate the periodontal status of patients with Multiple Sclerosis (MS) through clinical, microbiological, and biochemical parameters. Multiple sclerosis and periodontal diseases are both chronic inflammatory conditions that may share common immunopathological pathways. The primary objective is to investigate the relationship between MS and periodontal health by comparing clinical measurements with the microbial composition and biochemical markers found in saliva samples of patients followed by the Neurology Department.
NCT07415148
Periodontitis is a chronic inflammatory disease that leads to the destruction of the supporting tissues of the teeth. Non-surgical periodontal treatment is the first-line approach for the management of periodontitis; however, the use of adjunctive therapeutic agents may improve clinical outcomes. The aim of this randomized clinical trial is to evaluate the effects of hyaluronic acid gel and albumin platelet-rich fibrin (Alb-PRF) used as adjuncts to non-surgical periodontal treatment on clinical and biochemical parameters in patients with Stage III periodontitis. Participants will be randomly allocated into three groups: an Alb-PRF group, a hyaluronic acid gel group, and a control group receiving non-surgical periodontal treatment alone. Clinical periodontal parameters and biochemical markers obtained from gingival crevicular fluid will be assessed at baseline and at 1 and 3 months after treatment. The findings of this study are expected to contribute to the evaluation of the potential benefits of adjunctive biological and anti-inflammatory applications in the non-surgical periodontal treatment of patients with Stage III periodontitis.v
NCT07412795
The goal of this clinical study is to learn whether gum treatment can improve heart health. Researchers will compare blood markers related to heart disease before and after routine gum treatment. The main questions this study aims to answer are: Is gum disease a risk factor for heart disease? Can treating gum disease lower the risk of heart disease? Adults with stable angina (a type of heart disease) and adults without heart disease may take part in this study. All participants will receive routine, non-surgical gum treatment, which is a standard dental care procedure. This includes professional cleaning to remove plaque and tartar from the teeth and practical education on tooth brushing and cleaning between the teeth. The treatment will be performed by a single researcher and completed in one visit within about one hour. Participants will: Provide a blood sample before gum treatment Receive routine, non-surgical gum treatment Return after three months for a follow-up visit Provide a second blood sample This study does not involve experimental drugs or devices. Participation is voluntary, and there is no cost to participants. The results may help researchers better understand how gum health is related to heart health.
NCT07036289
Heart failure (HF) is a rapidly growing public health issue affecting more than 40 million individuals globally; while gum disease with bone loss affects 50% of people in general. The objective of this study is to evaluate the effect of dental treatment on blood levels of a HF parameter at 3 and at 6 months. In addition to verify the relation between blood and salivary exam results and severity of HF. Imune response against one important oral bacterial will be also monitored at 3 and 6 months. Approximately 80 adult individuals will be included and divided into 3 groups. The first two groups will receive dental scaling and root planing (periodontitis individuals with heart failure \[n = 25\]; periodontitis individuals without heart failure \[n = 25\]). The third group named negative control will receive dental treatment only after 6 months of dental follow-up (periodontitis individuals with heart failure \[n = 25\]). HF treatment by oral medication will be continuous. Blood, salivary, microbiological and immune examinations will be performed in addition to the periodontal treatment of scaling and root planning. Clinical data will be obtained both for initial diagnosis and disease staging and for longitudinal follow-up.
NCT07402694
Periodontitis is a chronic inflammation caused by dental plaque that can destroy periodontal tissues. Current primary treatments include mechanical removal methods such as supragingival scaling and subgingival curettage. However, issues like microbial recolonization leading to inflammation recurrence exist, often necessitating the use of antimicrobial agents. Prolonged antibiotic use, however, can easily lead to bacterial resistance. Amphion oral rinse is a novel biomimetic material mouthwash. It inhibits plaque regrowth by forming a long-lasting physical barrier and avoids flora imbalance. Compared with traditional antibiotics, this product has shown unique advantages in the adjuvant treatment of periodontal diseases. This study aims to evaluate the efficacy of Amphion rinse combined with conventional periodontal therapy in patients with stage I-IV periodontitis, including plaque control and inflammation improvement. Additionally, it will analyze its impact on the oral microbiome and collect user experience feedback to provide a reference for its clinical application.
NCT07395726
The purpose of this research is to assess the efficacy of Platelet-Rich Fibrin (PRF) in the regeneration of periodontal tissues in patients suffering from periodontal disease. Periodontal disease is a chronic inflammatory disease that affects the gums and the bone supporting the teeth, which can eventually result in the loss of teeth if left untreated. Conventional periodontal treatment can control the infection and halt the progression of the disease but cannot reverse the loss of the supporting structures. Platelet-Rich Fibrin is a biologic material derived from a small amount of the patient's own blood. It has growth factors that can potentially enhance healing and facilitate the regeneration of bone and soft tissues. In this randomized controlled clinical trial, patients will be randomly assigned to either conventional periodontal surgical treatment or conventional treatment along with PRF. Over a predetermined follow-up period, clinical measurements like gum pocket depth, attachment levels, and radiographic bone changes will be assessed to see if PRF offers any extra advantages in tissue healing and regeneration. The results of this study could improve long-term oral health outcomes and periodontal disease treatment approaches.
NCT06643676
Targeted endodontic microsurgery represents precise and advanced approach to resolving persisting chronic periapical periodontitis after non- surgical root canal treatment. This specialised procedure involves accessing the root tip of the tooth under high magnification using dental operating microscopes and employing microsurgical instruments to remove infected or inflamed tissue, as well as any pathological lesions present in the periapical region. Targeted Endodontic Microsurgery is useful for osteotomy and root- end resection when exacting control of depth, diameter, and angulation of osteotomy and root end resection is necessary. Using a CBCT(cone beam computed tomography) designed 3D - printed surgical guideis a more accurate method for access to the apical portion of the root during surgical endodontics compared with a "freehand" CBCT - approximated conventional method. These guided have the potential to increase accuracy and precision and to reduce intraoperative time as well as postoperative complications. Additionally, it provides a viable treatment option for patients who may not be candidates for traditional root canal therapy or retreatment due to anatomical complexities or previous treatment failures.

NCT07312552
The aim of this study is to evaluate the relationship between periodontal status and salivary levels of the inflammasomes NOD-like receptor family, pyrin domain containing 3 (NLRP-3), NOD-like receptor family, pyrin domain containing 6 (NLRP-6), NOD-like receptor family, pyrin domain containing 12 (NLRP-12), NOD-like receptor family, CARD domain containing 5 (NLRC-5), interleukin-1 beta (IL-1β) and interleukin-10 (IL-10). Furthermore, this study aims to investigate whether the salivary levels of these inflammasomes may serve as potential diagnostic biomarkers for distinguishing individuals with periodontitis from those without. In addition, the potential role of smoking in modulating the relationship between periodontal status and salivary inflammasome levels will also be explored.
