Evaluation of E-max Porcelain Veneer Failures: A Retrospective Study.

Aim This retrospective study aimed to evaluate if E-max veneers over five years caused changes in gingival, periodontal health, and veneer failures. Background As aesthetic dentistry progresses, dental veneers are becoming increasingly popular in both general and specialized dental practices. Due to technological advancements in dental ceramics and adhesive systems, porcelain veneers have become a highly sought-after solution for improving aesthetics in dental patients. The success of porcelain laminate veneers, a commonly used method for aesthetic restoration, relies on various factors. E-max veneers are frequently utilized, with their long-term durability contingent upon factors such as color stability, resistance to abrasion, as well as good compressive, tensile, and shear strength, along with maintaining marginal integrity. Methodology In this study, data was collected through a checklist form used to record clinical parameters. The clinical parameters evaluated were inflammation and bleeding on probing (BOP). The gingival health was evaluated by gingival index, gingival color, texture, and bleeding on probing, and periodontal health was evaluated by the pocket depth and radiographic evaluations. Finally, the veneer was visually inspected for chipping, staining, and debonding history. The score for most of the cases ranged between 0-1, with only 10 cases displaying moderate gingival inflammation and BOP (Gingival Index 2). Siemens Orthopantomogram (OPG) systems were used for radiological evaluation and documentation of cases. E-max porcelain veneers were only included in the research. Results Out of 28 patients, each with 6-to-10-unit veneer cases was examined, 18 patients (64.3%) displayed healthy gingival status with no bleeding area recorded in none of the veneers amongst the 6 to 10 units. In 10 patients (35.7%) most of the veneers had inflamed gingival tissue that was bleeding on probing. The majority revealed the presence of stippling (92.9%), absence of recession (96.4%), and pocket depth (67.9%). Half of our participants had their veneer for more than five years (50%) and the majority presented with no significant changes in veneer recorded like marginal staining, debonding, or chipping (89.3%). Conclusion Multiple factors such as patient selection, proper treatment planning, and design, including material selection, play a significant role in the long-lasting success of ceramic veneers. The retrospective study indicated that proper oral hygiene measures are vital for the long-term sustainability of E max veneers.

Management Strategies for Open Bite Relapse: A Systematic Review and Meta-Analysis.

The purpose of orthodontic therapy is to correct malocclusion and produce a stable outcome that endures over time. Long-term stability can be difficult to achieve, and many patients relapse after treatment, particularly in instances of open bite relapse (OBR). This systematic review aimed to analyze different types of management strategies for OBR and conduct a meta-analysis to find the best method of dealing with relapse. A comprehensive search was carried out across six major online databases using relevant keywords pertaining to our study, including "open bite relapse," "orthodontic retention," "orthodontic surgery," "orthodontic appliance," "orthodontic management," "orthodontic treatment," "orofacial myofunctional therapy (OMT)," "skeletal anchorage," and "treatment follow-up period." Eleven studies were selected after the application of relevant inclusion and exclusion strategies. The mean follow-up period of treatment for the studies ranged from six months to 4.5 years. Of all the management strategies assessed, OMT was found to be the least effective for OBR management. Surgical management modalities, such as mandibular repositioning and molar intrusion using skeletal anchorage, in conjunction with the usage of orthodontic appliances, were found to be noticeably effective, especially in the cases of participants who were <18 years of age. However, when utilized on a singular basis, either of them was found to be lacking the desired effect. The overall odds ratio (OR) of 0.48 (0.37, 0.64) and risk ratio (RR) of 0.62 (0.51, 0.74) were obtained after the meta-analysis of the different interventions for OBR, indicating statistical significance. There were only 11 studies included in the study, so it's possible that not all management strategies for OBR were fully understood. The limited number of studies may also have affected the generalizability of the findings. Although statistical differences were obtained to a certain degree, more clinical trials are needed to assess the effect of such surgical modalities as a viable management tool for OBR, since these represent a significant limiting factor in terms of the overall cost of the treatment placed upon the patient. Prior to the start of the research, registration was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. The research protocol was created to meet the goals and was properly filed with the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42023401991).

Comparing the Efficacy of Different Archwire Materials in Accelerating Orthodontic Tooth Movement.

Background: Orthodontic treatment is commonly used to correct misaligned teeth and improve dental aesthetics and function. Archwires play a crucial role in this treatment by exerting forces on teeth, prompting them to shift into desired positions. Materials and Methods: For this experimental study, 60 participants requiring orthodontic treatment were selected and divided into three groups: Group A, treated with stainless steel archwires; Group B, treated with nickel-titanium archwires; and Group C, treated with beta-titanium archwires. Standardized orthodontic procedures were followed for all participants. The rate of tooth movement was measured over a period of 6 months using digital models and a calibrated measurement technique. Results: The study revealed notable differences in the rate of orthodontic tooth movement among the three groups. Group B (nickel-titanium archwires) demonstrated the highest mean rate of tooth movement, with an average of 1.5 mm per month. Group A (stainless steel archwires) exhibited a mean rate of 1.2 mm per month, while Group C (beta-titanium archwires) showed the lowest mean rate at 0.9 mm per month. Conclusion: In conclusion, this study highlights the varying efficacy of different archwire materials in accelerating orthodontic tooth movement. Nickel-titanium archwires exhibited the highest rate of tooth movement compared to stainless steel and beta-titanium archwires.

The Use of Lasers in Enhancing the Bond Strength of Orthodontic Brackets.

Background: The use of lasers in orthodontics has garnered interest for its potential to enhance the bond strength between orthodontic brackets and tooth surfaces, a crucial factor for successful orthodontic treatment. This study aims to investigate the effect of laser irradiation on the bond strength of orthodontic brackets in a sample of 30 patients. Materials and Methods: Thirty patients undergoing orthodontic treatment were divided into two groups. In Group A, brackets were bonded using conventional methods, while in Group B, brackets were bonded after laser irradiation. A diode laser operating at 810 nm was used, with an energy setting of 2.5 W for 20 s. After bonding, a universal testing machine measured the bond strength in megapascals (MPa). The adhesive remnant index (ARI) was also recorded to determine the mode of bond failure. Statistical analyses were conducted to compare the results between the groups. Results: The mean bond strength in Group B (laser irradiation) was significantly higher (P < 0.05) than in Group A (conventional bonding). Group B exhibited a mean bond strength of 9.72 MPa, whereas Group A showed a mean bond strength of 7.41 MPa. The ARI scores indicated that Group B had more adhesive remaining on the tooth surface, suggesting a stronger bond. Conclusion: Laser irradiation prior to orthodontic bracket bonding resulted in significantly enhanced bond strength compared to conventional bonding methods. The increased bond strength and greater adhesive remnant on the tooth surface indicate that laser irradiation improves the adhesion between brackets and tooth enamel. Integrating lasers into orthodontic procedures has the potential to elevate treatment outcomes by ensuring durable bracket adhesion.

The Effect of Early Orthodontic Treatment on Long-Term Stability of Class II Malocclusions.

Background: Class II malocclusions are a common dental issue characterized by the misalignment of the upper and lower teeth. Early orthodontic treatment is often considered to correct these malocclusions, but its long-term effectiveness remains unclear. Materials and Methods: In this study, we examined the impact of early orthodontic treatment on the long-term stability of Class II malocclusions. We conducted a retrospective analysis of dental records from a sample of 150 patients who had received early orthodontic treatment for Class II malocclusions. The treatment involved braces and other orthodontic appliances. We compared their dental measurements before and after treatment, with a follow-up period of 5 years. Results: Our analysis revealed that the early orthodontic treatment led to a significant improvement in the alignment of upper and lower teeth, as indicated by a reduction in the overjet (the horizontal distance between upper and lower incisors). The mean overjet reduction was 3.2 millimeters. Furthermore, the Angle's Class II molar relationship was corrected in 80% of the cases. Conclusion: Early orthodontic treatment for Class II malocclusions demonstrated positive long-term stability, as evidenced by a reduction in overjet and improvement in molar relationships.

The Efficacy of Platelet-Rich Plasma as an Adjunct to Bone Grafting in Alveolar Ridge Preservation Following Tooth Extraction.

Background: Tooth extraction often results in bone loss in the alveolar ridge, which can complicate subsequent dental implant placement. Alveolar ridge preservation (ARP) techniques, such as bone grafting, aim to mitigate this bone loss. Platelet-rich plasma (PRP) has been proposed as an adjunct to bone grafting in ARP to enhance bone regeneration. Materials and Methods: A total of 60 patients requiring tooth extraction and ARP were included in this randomized controlled trial. Patients were divided into two groups: Group A received bone grafting alone, while Group B received bone grafting with PRP. Clinical and radiographic assessments were performed at baseline and 6-month postsurgery. Bone density and height were measured using arbitrary values. Results: At the 6-month follow-up, Group B demonstrated a statistically significant increase in bone density (P < 0.05) and bone height (P < 0.05) compared to Group A. The arbitrary values for bone density in Group B increased by 15% and bone height increased by 10% compared to baseline measurements. Group A showed minimal improvement. Conclusion: The incorporation of PRP as an adjunct to bone grafting in ARP following tooth extraction significantly enhances bone density and height, suggesting its efficacy in preserving the alveolar ridge.

Assessing the Impact of Smoking Cessation Interventions on Periodontal Health and Gingival Inflammation in Smokers with Periodontitis.

Background: Smoking is a well-established risk factor for periodontitis, a chronic inflammatory disease of the oral cavity. While smoking cessation has been linked to improved overall health, its specific impact on periodontal health and gingival inflammation in individuals with periodontitis remains less explored. Materials and Methods: We conducted a prospective cohort study involving 200 smokers diagnosed with periodontitis. Participants were divided into two groups: Group A received comprehensive smoking cessation interventions, including counseling and pharmacotherapy, while group B continued smoking without intervention. Periodontal health was assessed through clinical parameters, including probing depth (PD) and clinical attachment level (CAL), at baseline and 6 months post intervention. Gingival inflammation was evaluated using the Gingival Index (GI). Results: After 6 months, group A exhibited a significant reduction in mean PD (from 4.5 mm to 3.2 mm) and CAL (from 5.0 mm to 3.5 mm) compared to group B. Conversely, group B showed no significant change in these parameters. The GI score significantly decreased in group A (from 2.8 to 1.2) but remained unchanged in group B. Furthermore, group A demonstrated a higher rate of smoking cessation (72%) compared to group B (14%). Conclusion: Smoking cessation interventions play a crucial role in improving periodontal health and reducing gingival inflammation in smokers with periodontitis. The observed reductions in PD, CAL, and gingival inflammation highlight the potential benefits of smoking cessation on oral health outcomes in this high-risk population.

Evaluation of Micro-Osteoperforations in Expediting Orthodontic Tooth Movement in Adult Patients.

Background: Orthodontic tooth movement, the process of aligning teeth, can often be time-consuming, particularly in adult patients. Micro-osteoperforations (MOPs) have emerged as a potential technique to accelerate this process. Materials and Methods: A sample of 30 adult patients undergoing orthodontic treatment was selected. The patients were divided into two groups: an experimental group (EG) receiving MOPs and a control group (CG) without MOPs. Standard orthodontic treatment was administered to both groups. The rate of tooth movement was measured using digital models and recorded in millimeters per month. Pain levels reported by patients were also noted. The data were analyzed using basic statistical methods. Results: The EG demonstrated a significantly higher rate of orthodontic tooth movement compared to the CG. The average rate of tooth movement in the EG was 1.5 millimeters per month, while the CG exhibited an average rate of 0.8 millimeters per month. Additionally, pain levels reported by patients in the EG were slightly elevated immediately after MOPs but subsided within a few days. Conclusion: The findings of this study suggest that MOPs can effectively expedite orthodontic tooth movement in adult patients.

Comparing the Efficacy of Different Maintenance Intervals on Preventing Disease Recurrence in Patients with A History of Periodontal Treatment.

Background: Scheduled maintenance appointments after periodontal treatment are very much critical for the success of the treatment. This is necessary for patients seeking to prevent disease recurrence and maintain oral health. Materials and Methods: In this study, we conducted a comprehensive analysis to assess the efficacy of various maintenance intervals in preventing disease recurrence among patients with a history of periodontal treatment. We gathered data from a diverse group of patients who had undergone periodontal treatment and tracked their oral health over an extended period. Results: Our findings reveal compelling insights into the optimal maintenance intervals. Patients who attended maintenance appointments at three-month intervals showed a significant reduction in disease recurrence by 40%, compared to those at six-month intervals. Moreover, those on annual intervals experienced a disease recurrence rate of 60. Conclusion: In conclusion, our study underscores the importance of regular maintenance appointments after periodontal treatment. Patients who attend appointments every three months have a significantly lower risk of disease recurrence. These findings emphasize the need for tailored maintenance schedules to ensure long-term oral health.

Accelerated Orthodontic Treatment Using Photobiomodulation: A Randomized Clinical Trial.

Background: Orthodontic treatment (OT) aims to align and correct teeth positions. However, conventional treatment methods often require a considerable amount of time. Photobiomodulation (PBM) has emerged as a potential solution to OT. Materials and Methods: The study included 60 patients, divided equally into two groups: the PBM group and the control group. Patients in the PBM group received light therapy sessions applied directly to the OT area during each visit. Both groups underwent regular orthodontic adjustments. Treatment duration, changes in tooth alignment, and patient discomfort were evaluated. Statistical analysis was performed to compare the outcomes between the groups. Results: The results of the study indicated that the PBM group experienced a statistically significant reduction in treatment duration compared to the control group. Moreover, there were noticeable improvements in tooth alignment in both groups. Patients in the PBM group reported minimal discomfort during the treatment process. These findings suggest that PBM has the potential to expedite OT without compromising its effectiveness. Conclusion: In conclusion, this randomized clinical trial demonstrates that PBM can be an effective approach to accelerate OT. The technique led to a significant reduction in treatment duration and was well-tolerated by patients.

AI algorithms were trained using dental images, and their performance was evaluated against the clinical examination results. Results: The AI-based detection system demonstrated a sensitivity of 92% and a specificity of 85% in identifying dental caries, with an overall accuracy of 88%. The clinical examination yielded a sensitivity of 86% and a specificity of 90%, resulting in an overall accuracy of 88%. Statistical analysis indicated no significant difference between AI-based detection and clinical examination (P > 0.05). Conclusion: AI technology exhibits promise as an adjunctive tool for dental practitioners, potentially reducing diagnostic errors and improving efficiency. Integrating AI into routine dental practice may aid in early caries detection and promote better oral health outcomes.

Exploring the Oral Manifestations and Hazards to Dental Professionals During the COVID-19 Pandemic: A Scoping Review.

The novel coronavirus (COVID-19) has inundated the whole world by causing severe acute respiratory syndrome in humans, thus posing serious public health concerns. The oral and olfactory systems are significantly impacted by the COVID-19 condition, in addition to the respiratory and digestive systems. Oral symptoms of COVID-19 can be caused by a loss in oral hygiene, immune system suppression, a decline in general health, and candidiasis due to prolonged antibiotic use. Because many aerosols and droplets are produced during various dental operations, dental professionals and dentists are at a significant risk of contracting the COVID-19 infection. Few precautionary measures include performing a pre-appointment health screening for all patients, performing aerosol-producing procedures in a designated space or operatory, using proper personal protective equipment and disinfecting the operatory between patients, and limiting the number of dental procedures at one time. Against this background, the purposes of this article are to explore the oral presentations of COVID-19 infection and to emphasize the hazards to dental professionals during COVID-19 pandemic. Additionally, few preventive measures are also highlighted.

Comparing the Long-term Success Rates of Immediate Implant Placement vs. Delayed Implant Placement in Patients with Periodontally Compromised Teeth.

Background: This study aims to compare the long-term success rates of immediate implant placement and delayed implant placement in patients with periodontally compromised teeth. Materials and Methods: A total of 30 patients presenting with periodontally compromised teeth requiring extraction and subsequent implant placement were enrolled in this retrospective study. Patients were divided into two groups based on the timing of implant placement: Group A (immediate implant placement) and Group B (delayed implant placement). Implants were placed according to standard protocols. Patient records were reviewed for implant survival, peri-implant bone loss, and prosthetic complications. Data were statistically analyzed using appropriate tests. Results: The mean follow-up period was 5 years. In Group A, the implant survival rate was 90%, while in Group B, it was 83%. The mean peri-implant bone loss was 1.5 mm in Group A and 2.2 mm in Group B. Prosthetic complications were observed in three cases in Group A and five cases in Group B. The differences in implant survival and bone loss between the two groups were not statistically significant (P > 0.05). Conclusion: Both immediate implant placement and delayed implant placement demonstrated comparable long-term success rates in patients with periodontally compromised teeth.

Surgical vs. Non-Surgical Management of Temporomandibular Joint Disorders: Clinical Outcomes.

Background: Temporomandibular joint disorders (TMDs) encompass a range of clinical conditions affecting the temporomandibular joint (TMJ) and associated structures. Management approaches for TMDs vary and include both surgical and non-surgical interventions. Materials and Methods: In this retrospective cohort study, medical records of 150 patients diagnosed with TMDs were reviewed. Patients were categorized into two groups: surgical intervention and non-surgical intervention. The surgical group underwent various surgical procedures, including arthroscopy, arthroplasty, and joint replacement, while the non-surgical group received conservative treatments such as physical therapy, pharmacotherapy, and occlusal splints. Pain levels, TMJ function, quality of life (QoL), and patient satisfaction were assessed at baseline and post-treatment (6 months and 1 year). Results: At the 6-month follow-up, both groups experienced a significant reduction in pain scores (surgical group: 6.3 ± 1.2 to 2.4 ± 0.9, non-surgical group: 6.1 ± 1.1 to 3.2 ± 1.0). TMJ function improved in both groups (surgical group: 2.5 ± 0.8 to 4.8 ± 0.6, non-surgical group: 2.6 ± 0.7 to 4.2 ± 0.9). QoL scores increased (surgical group: 35.2 ± 4.6 to 50.3 ± 5.1, non-surgical group: 35.5 ± 4.2 to 45.7 ± 4.8), and patient satisfaction rates were high (surgical group: 92%, non-surgical group: 87%) at the 1-year follow-up. Conclusion: Both surgical and non-surgical management approaches demonstrated significant improvements in pain relief, TMJ function, QoL, and patient satisfaction for individuals with TMDs.

Assessment of AI Models in Predicting Treatment Outcomes in Orthodontics.

Background: In the realm of orthodontics, the evaluation of treatment outcomes is a pivotal aspect. In recent times, artificial intelligence (AI) models have garnered attention as potential tools for predicting these outcomes. These AI models have the potential to enhance treatment planning and decision-making processes. However, a comprehensive assessment of their effectiveness and accuracy is essential before their widespread integration. Materials and Methods: In this study, we assessed the capability of AI models to predict treatment outcomes in orthodontics. A sample of 30 patients undergoing orthodontic treatment was selected. Various patient-specific parameters, including age, initial malocclusion severity, and treatment approach, were collected. The AI model was trained using a dataset comprising historical treatment cases and their respective outcomes. Subsequently, the trained AI model was applied to predict the treatment outcomes for the selected patients. Results: The results of this study indicated a moderate level of accuracy in the predictions made by the AI model. Out of the 30 patients, the model accurately predicted treatment outcomes for 22 patients, yielding a success rate of approximately 73%. However, the model exhibited limitations in accurately predicting outcomes for cases involving complex malocclusions or those requiring non-standard treatment approaches. Conclusion: In conclusion, this study underscores the potential of AI models in predicting treatment outcomes in orthodontics. While the AI model demonstrated promising accuracy in the majority of cases, its efficacy was diminished in complex and non-standard cases. Therefore, while AI models can serve as valuable tools to aid orthodontists in treatment planning, they should be utilized in conjunction with clinical expertise to ensure optimal decision-making and patient care.

Effectiveness of Early Intervention with Palatal Expansion Versus Late Orthodontic Treatment for Correcting Maxillary Crowding.

Background: Maxillary crowding is a common orthodontic issue that can impact a patient's oral health and overall well-being. The timing of orthodontic treatment plays a crucial role in achieving optimal results. Materials and Methods: Thirty patients who received early intervention with palatal expansion (Group A) and 30 patients who underwent late orthodontic treatment (Group B) were included in this study. The age range for Group A was 8-10 years, while Group B had an age range of 16-18 years. Pretreatment and posttreatment records, including dental models and cephalometric radiographs, were analyzed to assess the effectiveness of the respective treatments. Results: In Group A, the mean duration of treatment was 12 months, and the maxillary crowding was corrected by an average of 4.5 mm. In Group B, the mean treatment duration was 24 months, and maxillary crowding was corrected by an average of 3.2 mm. The early intervention group (Group A) exhibited a statistically significant reduction in treatment duration and greater correction of maxillary crowding compared to the late orthodontic treatment group (Group B) (P < 0.05). Conclusion: Early intervention with palatal expansion is an effective approach for correcting maxillary crowding, leading to shorter treatment duration and greater improvement compared to late orthodontic treatment.

Comparing the Clinical and Radiographic Outcomes of Two Different Surgical Approaches for Treating Infrabony Defects in Chronic Periodontitis Patients.

Background: Chronic periodontitis is a prevalent oral health issue, affecting a substantial portion of the population. Infrabony defects, characterized by bone loss around teeth, are a hallmark of this condition and require surgical intervention to prevent further damage and tooth loss. Two commonly used surgical approaches are open flap debridement (OFD) and guided tissue regeneration (GTR). Materials and Methods: This prospective cohort study included 60 patients with chronic periodontitis and infrabony defects. Patients were randomly assigned to either the OFD or GTR group. Clinical parameters, including probing depth (PD) and clinical attachment level (CAL), were recorded at baseline and at 6-month and 12-month follow-up appointments. Radiographic assessments were conducted using periapical radiographs. The primary outcome measures were changes in PD and CAL, while secondary outcomes included radiographic evidence of bone regeneration. Results: At the 6-month follow-up, the OFD group demonstrated an average reduction in PD of 2.4 mm (SD = 0.8) and an increase in CAL of 1.6 mm (SD = 0.5). In contrast, the GTR group showed a reduction in PD of 2.1 mm (SD = 0.7) and an increase in CAL of 1.9 mm (SD = 0.6). These differences were not statistically significant (P > 0.05). Radiographic analysis indicated a mean bone fill of 1.2 mm (SD = 0.4) in the OFD group and 1.4 mm (SD = 0.3) in the GTR group at 12 months, with no significant difference observed between the two groups (P > 0.05). Conclusion: In this study, both OFD and GTR approaches demonstrated comparable clinical and radiographic outcomes in the treatment of infrabony defects in chronic periodontitis patients.

The Effect of a Low-Carbohydrate Diet on Periodontal Health and Inflammation in Patients with Type 2 Diabetes.

Background: The interaction between type 2 diabetes and periodontal disease underscores the importance of exploring dietary interventions that could mitigate inflammation and improve periodontal health in diabetic patients. Materials and Methods: This randomized controlled trial included 100 patients with type 2 diabetes who were equally divided into two groups: Group A (low-carbohydrate diet) and Group B (control group). Patients in Group A followed a low-carbohydrate diet for 12 weeks, while Group B maintained their regular dietary habits. Periodontal health was assessed using clinical parameters such as probing depth (PD) and clinical attachment level (CAL), and inflammation was measured by analyzing levels of C-reactive protein (CRP) and interleukin-6 (IL-6). Statistical analyses were performed using appropriate tests. Results: After 12 weeks, Group A exhibited significant improvements in periodontal health compared to Group B. The mean PD reduction was 0.5 mm in Group A and 0.1 mm in Group B, with a corresponding mean CAL gain of 0.3 mm in Group A and no significant change in Group B. Inflammatory markers also showed favorable outcomes in Group A, with a decrease of 1.2 mg/L in CRP levels and 20% reduction in IL-6 levels. In contrast, Group B demonstrated minimal changes in inflammatory markers. The differences in PD, CAL, CRP, and IL-6 levels between the two groups were statistically significant (P < 0.05). Conclusion: The adoption of a low-carbohydrate diet for 12 weeks demonstrated significant improvements in periodontal health and reduction of inflammation in patients with type 2 diabetes.
