Dental Pain

The aim of the present study is to assess the changes of palatal morphology among growing patients with different vertical facial growth patterns treated with rapid palatal expander. Thirty-six patients referred to "Policlinico Agostino Gemelli" university hospital will be selected. The eligible criteria are posterior cross-bite, mixed dentition, skeletal Class I relationship and prepubertal stage of cervical vertebral maturation. The patients will be split into three groups according to facial divergency (hyper-, hypo-, normodivergent subjects). For each subject, digital dental casts will be recorded before and after treatment using an intraoral scanner. To evaluate two-dimensional maxillary arch changes, linear measurements will be done. To study comprehensively the palatal shape, a set of 240 landmark and semi-landmarks will be digitized on the palatal vault. Then, Geometric Morphometric Analysis (GMA) will be performed to compare morphological variations of the palate among different vertical facial growth pattern groups.

Keratinized tissue deficiency and gingival recession are common mucogingival problems that may compromise periodontal health, esthetics, and patient comfort. Soft tissue grafting procedures are widely used to increase tissue thickness and volume and to achieve keratinized tissue augmentation. Among autogenous grafting techniques, free gingival grafts (FGG) are considered a predictable and reliable approach for enhancing soft tissue stability and long-term marginal tissue outcomes. Despite their effectiveness, conventional FGG procedures may exhibit postoperative shrinkage and volume reduction due to limited vascularization at the recipient site. To overcome this limitation, a modified free gingival graft (ModFGG) technique has recently been introduced. In this technique, a connective tissue pedicle flap harvested from the apical region of the recession defect is used to cover the exposed root surface prior to placement of the free gingival graft, with the aim of improving graft vascularization and enhancing wound healing. Although previous studies have reported favorable outcomes for ModFGG in terms of root coverage, keratinized tissue gain, and patient satisfaction, available evidence is largely based on two-dimensional clinical measurements. Conventional methods used to assess soft tissue changes, such as periodontal probing, needles, and ultrasonic devices, are either invasive or limited to linear measurements, thereby restricting the evaluation of volumetric tissue alterations. Recent advances in three-dimensional digital analysis techniques allow for reliable, non-invasive, and reproducible assessment of both linear and volumetric soft tissue changes. However, to date, no clinical study has evaluated soft tissue thickness, volumetric changes, and creeping attachment following conventional FGG and ModFGG procedures in mandibular incisors using direct three-dimensional digital analysis. This randomized controlled clinical trial aims to compare the effects of conventional free gingival graft and modified free gingival graft techniques on soft tissue thickness, volumetric changes, and creeping attachment in mandibular incisors using a direct three-dimensional digital evaluation method. Systemically healthy, non-smoking adult patients presenting with localized Cairo Class II gingival recession will be enrolled and randomly allocated to either the FGG (control) group or the ModFGG (test) group. Clinical and digital assessments will be performed at baseline and at 1, 3, and 6 months postoperatively. Soft tissue thickness and volumetric changes will be analyzed by superimposing digital models obtained using an intraoral scanner. Additional clinical parameters, including gingival recession depth, width of keratinized tissue, and probing depth, will also be recorded. The results of this study are expected to provide high-quality evidence regarding the effectiveness of the modified free gingival graft technique in enhancing soft tissue stability and volumetric outcomes in periodontal plastic surgery.

The goal of this clinical trial is to evaluate the clinical efficacy of an antimicrobial mouthrinse, with a particular focus on its effect on established plaque and the improvement of gum health. Participants will: * Brush and rinse twice a day with the designated products for 6 months * Visit the clinic once every 3 months after baseline for reassessment.

The current randomized clinical trial will be conducted to evaluate the 24-month clinical and radiographic outcomes after revascularization of asymptomatic necrotic immature permanent maxillary incisors using single- or multiple-visit protocol.

Patients diagnosed with stage III or IV periodontitis who exhibit mandibular first or second molars with Class II, Subclass A, or B buccal and/or lingual mandibular furcation defects (horizontal probing depth of ≥ 3 mm ) will be recruited. Patients diagnosed with stage III or IV periodontitis who exhibit maxillary first or second molars with Class II, Subclass A, or B buccal furcation defects (horizontal probing depth of ≥ 3 mm ) if furcation involvement on the palatal side (mesiopalatal and distopalatal) does not exceed Class 1 will be recruited. This study will be a prospective, randomized, single-blinded, controlled clinical trial with a split-mouth design. Patients will be recruited from the clinics of the Riga Stradiņš University Institute of Stomatology of Riga, Latvia. Before the baseline treatment, all patients who meet the inclusion criteria will be given detailed oral hygiene instructions and motivation. Patients' furcation defects in each quadrant will be randomly allocated at a 1:1 ratio to either the application of Oscillating Chitosan Brush with Enamel Matrix Derivatives (test group) or Oscillating Chitosan Brush alone (control group). Non-surgical periodontal treatment of furcation defects on the test side will be performed through the application of Oscillating Chitosan Brush with Enamel Matrix Derivatives and on the control side with Oscillating Chitosan Brush alone. The re-evaluation of periodontal status will be performed 12 weeks following the baseline treatment. Biofilm samples and gingival crevicular fluid (GCF) samples will be taken at the baseline and at 4 weeks.

Multi-center, prospective, single-blind, randomized and parallel controlled trials are used to evaluate the role and impact of "digital chronic pain treatment system equipment" based on MR mixed reality technology in the clinical basic treatment of patients clinically diagnosed with chronic pain.

This will be a single-center, 24-week, randomized, controlled, single blind (examiner only), 3-treatment arms, parallel group, stratified study, to evaluate the efficacy of using an experimental dentifrice containing 0.454% w/w Stannous fluoride, twice daily in reducing gingivitis and plaque accumulation in a population with clinically measurable level of gingivitis. The clinical efficacy of the experimental dentifrice will be compared to a commercially available regular fluoride dentifrice as negative control. In addition, a marketed dentifrice containing 0.454% w/w SnF2 is included as positive control to provide a well-established benchmark. Approximately 300 participants (approximately 100 per group) will be randomized to ensure approximately 270 evaluable participants (approximately 90 per group) complete the study.

DH has a prevalence rate ranging from 1.3% to 92.1%, commonly affecting old ages, and the frequency of DH in patients suffering from periodontal disease is 3-57%. Pakistan has reported prevalence from different cities, with 36.4% from Karachi and 22% from Lahore. The use of laser has opened new dimensions in the treatment of DH. Theories that support laser therapy explain that irradiation blocks the pain in dentinal tubules by melting and recrystallization of dentin or by tertiary dentine production or evaporation of dentinal fluid. Considering the oral soft tissues which contain high amounts of water, Lasotronix SMARTm laser diodes have been carefully designed to show their high transmission. The 635nm wavelength is optimal for activating tolonium chloride dye for photo-activated chemo therapy, eliminating all bacteria and biofilms without any side effects. 200 mW power provides safe cold bio stimulation and photo disinfection within a reasonably short therapy time. Application of Sodium fluoride (NaF) has also been indicated for hypersensitivity pains. Its application in the form of gel occludes the tubule by calcium fluoride precipitation. Agents like potassium nitrate also have promising effects, which increase the concentration of potassium ions in nerve endings and alter the nerve action potential in conducting the sensory stimuli. Recently DH treatment has been conducted with different types of laser with different wavelengths, either alone or in combination with desensitizing agents and varnishes and has revealed effective results. To the author's knowledge, not much research work has been conducted using LASOTRONIX as a treatment modality with CPP-ACP. Therefore, this research aims to determine the effectiveness of Casein phospho peptide paste (CPP-ACP) used alone or combined with a diode laser (LASOTRONIX).

Dental interventions in young children are challenging due to limited compliance and anxiety. Moisture control during the placement of resin composite fillings is particularly difficult, as children need to remain calm. Reducing treatment time benefits both children and dentists. The planned clinical investigation aims to evaluate the clinical performance and safety of posterior restorations on primary teeth using a flowable composite with a fast curing mode (5 seconds, 2000 mW/cm²) compared to a conventional curing mode (10 seconds, 1200 mW/cm²).

The aim of the study is to check whether vagus nerve stimulation (VNS) combined with manual therapy (TM), given its neuroanatomical relationship with the structures involved in pain in the TMJ, is more effective in reducing pain, increasing joint range and increasing the quality ofthe patient lives than TM alone. The research team is made up of three physiotherapists. It has been decided to distribute the tasks as follows: * Physiotherapist 1 will be in charge of the treatment of all patients. * Physiotherapist 2 will be responsible for screening the sample and evaluating the study. * Physiotherapist 3 will be in charge of analyzing the results and statistics. This component of the team, being blinded and not knowing the group of origin of the patient, will be able to interpret the results without any type of convenience bias, showing absolutely transparency in the elaboration of the conclusions. Once the screening will be completed, the patients will be divided into two groups: an experimental group (TM + ENV) and a control group (TM + ENV placebo).The randomization will be carried out through the statistical program Epidat 4,237 9 obtaining two homogeneous groups. Each patient will be assigned a code with the aim that the physiotherapist who is in charge of the statistical analysis is not able to establish links between the data and the subjects to which it refers.
