Microleakage scores have indicated restorations with biofillers showed best results followed by megafillers, incremental horizontal build-up, and bulk filling.
Biofillers provide a novel approach in improving microleakage and marginal adaptability of composite resin restorations.
Incorporation of inserts, which are capable of adequate bonding to resin and tooth, may provide improved marginal adaptability and reduce microleakage around restorative margins.

The purpose of this study is to evaluate the diagnostic accuracy of cone-beam computed tomography (CBCT) and extraoral bitewings in the detection of interproximal caries compared to intraoral bitewings.
Seven preserved cadaver heads with 106 teeth (molars, premolars, and canines) including 183 proximal surfaces were used. Five r adiographic modalities were studied intraoral bitewings, extraoral bitewings, iCAT 3D, ProMax 3D high r esolution, and ProMax 3D low r esolution. Seven pediatric dental r esidents were r ecruited and calibrated as observers and asked to evaluate each proximal surface. Teeth were extracted, mounted, drilled, caries detection dye was applied, and the surfaces were examined under the light microscope. Interexaminer r eliability, sensitivity, specificity, and area under the curve values were compared.
No significant differences were found in sensitivity, specificity, and area under the curve values between the five r adiographic modalities. R estorations may influence the accuracy of caries diagnosis.
Cone-beam computed tomography radiographs and extraoral bitewings showed similar accuracies in detecting interproximal caries compared to intraoral bitewings. This suggests that with proper training and experience, CBCT and extraoral bitewings could be comparable to intraoral bitewings in detecting interproximal caries.
Cone-beam computed tomography and extraoral bitewings could potentially serve as alternatives to intraoral bitewings to diagnose proximal caries, especially when the CBCT study is needed for a specific diagnostic purpose.

The growth of the temporomandibular joint (TMJ) gets affected by multiple factors like aging, occlusion state, and by the movement of the jaw while masticating and swallowing. Radiographic imaging is often utilized as a vital diagnostic adjunct in the evaluation of certain examinations of the TMJ.
In this
study, 30 male participants with mean age 55 years, having edentulous maxillary and mandibular arches from the Outpatient Department of Prosthodontics, were randomly selected. Group I (
= 30) patients who were edentulous for the last 4-5 years but without wearing dentures. Whereas group II (
= 30) patients who were edentulous for the last 4-5 years but were wearing dentures for this period. Maxillary and mandibular dentures were fabricated and delivered to subjects. Subjects were subjected to the TMJ analysis with the help of CBCT. Radiological images of dentomaxillofacial structures were analyzed by a specialist with a dual monitor inside a darkened silent room. On the monitor, three times measurd to subjects having normally maintained occlusion. The anatomical changes inside the TMJ have been much greater expressed within the completely edentulous subjects in whom the angle of sagittal condyle path declines and so does the articular eminence height.
It is essential to provide the edentulous patient with early prosthetic and occlusal rehabilitation after extractions to prevent the anatomical changes in TMJ.

Peri-implantitis is a key concern for dental implants and the main common reason for implant failure. This investigation evaluated the risk factors and their implications on peri-implantitis.
A retrospective search of the patients' clinical notes was performed to identify the documented cases of peri-implantitis. The inclusion criteria encompassed patients who were 18 years and older and were seen at the School of Dental Medicine, University of Nevada, Las Vegas, from January 2014 through September 2018. The search revealed that the number of peri-implantitis cases was 28, with an overall 45 implants. Proteasome cleavage Data were collected and analyzed using the Chi-square test.
Total 28 patients presented with peri-implantitis. The distribution of males to females with peri-implantitis was 60.7 and 39.3%, respectively. The highest number of patients (21.4%) presenting with peri-implantitis fell within the age range of 65-69 years; 53.3% of peri-implantitis cases were in the maxillary arch. The predilection area for peri-implantitis was the mandibular first molar (24.4%). Periodontitis was the most significant cause (60.7%); respiratory diseases (42.9%) followed by hypertension (28.6%) were the most prevalent medical conditions in the studied population. Peri-implantitis occurred most frequently among Caucasians (62.7%), followed by Hispanics (29%).
Within the limitations of the current evaluation, findings support previous claims that periodontitis remains the strongest predictor of peri-implantitis. A correlation may exist between peri-implantitis and the location of the implant and respiratory disease.
The implant location, the presence of periodontitis, and respiratory diseases are considered to be risk factors for peri-implantitis.

To assess microtensile bond strength (μTBS) of two types of luting cement to monolithic zirconia and dentin following various surface modifications and aging.
Monolithic zirconia blocks were divided into four main groups. Group N no surface modification; Group SB sandblasted using 50 μm Al
O
particles. Group GH glazed with a thin film of low-fusing porcelain glaze and etched with 10% hydrofluoric acid for 60 seconds. Group CJ sandblasted with CoJet sand. Surface-treated ceramic blocks were bonded to dentin using either self-adhesive cement or resin-modified glass ionomer cement and submitted to 3 or 150 days of water storage protocol with aging. The specimens were subjected to tensile force until de-bonding. Surface roughness (Ra, μm) was assessed after surface treatment. Analysis of variance (ANOVA) tests followed by Tukey's tests were used to analyze the data (
= 0.05).
Surface modification using selective infiltration etching (SIE) showed significantly higher μTBS (
< 0.05) compared to tribis an alternative luting cement for monolithic zirconia based on the assessment of its bond strength and bond durability.
The present study aimed to assess the effect of fluoridated and nonfluoridated mouth ri nses on resistance to friction between orthodontic bracket and archwire.
This study comprises 60 premolar stainless steel (SS) brackets with 0.022 inches slot size. The 0.019 × 0.025 dimensions SS archwires were cut into 5 cm long specimens. They were grouped into three main categories, group I artificial saliva (control solution), group II Aloe Dent mouthwash (ALO), and group III 0.05% sodium fluoride mouthwash. The specimens from each group were either immersed in the test solution or in the control solution for 10 hours. Later, the specimens were transferred to an incubator maintained at 37°C. Post 10 hours, the specimens were immersed for 30 minutes in distilled water. A scanning electron microscope was used to study the surface morphology and a universal testing machine was used to measure the frictional resistance.
The distribution of normality for three study groups' recorded data was checked using Shapiro-Wil movement of tooth, and also results in anchorage loss. So, orthodontists should always take care while prescribing mouthwashes to reduce their effects on the friction.
During sliding mechanism, the frictional resistance between orthodontic archwire and brackets imposes problems, such as lessening the applied force and movement of tooth, and also results in anchorage loss. So, orthodontists should always take care while prescribing mouthwashes to reduce their effects on the friction.
This study sought to examine the effectiveness of hybrid learning utilizing WhatsApp as an adjunct to traditional learning in delivering knowledge to and supporting the learning of undergraduate dental students and investigate learner perceptions of WhatsApp use in educational contexts.
The 3-month prospective analytical interventional study sampled 85 undergraduate students from the Department of Preventive Dental Sciences. A WhatsApp group was created, information was sent to the male and female groups, and a written assignment was used as a performance benchmark of knowledge acquisition and application. Perceptions of e-learning through WhatsApp were assessed using a previously validated and published questionnaire. Collected data underwent descriptive and bivariate analyses (unpaired
-test).
The average assignment scores of the 85 hybrid learners were statistically significantly higher than those of traditional learners from the previous academic year (34 ± 1 vs 26 ± 3;
< 0.05, respectively)s a convenient new teaching tool.
The results of this study may be applicable to other clinical dental disciplines.

To assess the application of clotrimazole (1%) as a complementary antifungal agent along with sodium hypochlorite (5.25%), chlorhexidine gluconate (2%), and doxycycline hydrochloride (5%) against
.
Seventy freshly extracted single-rooted premolars with matured apices were collected, stored, and handled according to the Occupational Safety and Health Administration (OSHA) and the Center for Disease Control and Prevention (CDC) guidelines and recommendations. These were divided into three groups (two tests and one control group) depending on irrigants used. The efficacy of each irrigant group was compared. The observations were statistically analyzed by the multiple intergroup comparisons using ANOVA and Scheffe multiple comparisons (
< 0.001).
The sodium hypochlorite (group IA-mean 129.6) has shown a statistically significant decrease in colony-forming units (CFUs) (
< 0.01) on comparison with chlorhexidine [(IB) mean 190.2]. A similar result was obtained in comparison with the sodium hypochlcy of the various endodontic irrigants and also determined their efficiency with the addition of the antifungal agent. Clotrimazole (1%) addition in irrigating solutions showed better results and promoted faster healing.
To evaluate the caries preventive and antibacterial effects of Gum Arabic and Licorice mouthwashes vs chlorhexidine in high caries-risk patients. The prevalence of oral side effects from using the mouthwashes was also assessed.
Total 63 participants categorized as high caries-risk according to the CAMBRA caries-risk model were recruited. They were randomly allocated to three groups (
= 21) according to the mouthwash used G1 (Gum Arabic), G2 (Licorice), and G3 (Chlorhexidine). Baseline DMF scores and saliva samples were obtained. DMF scores, salivary
(SM) and
(LA) counts, and any reported oral side effects were recorded after 3, 6, 9, and 12 months. The obtained results were subjected to the statistical analysis and the significance level was set at
≤ 0.05.
Regarding DMF scores, no statistically significant difference was found between the three groups at baseline, after 3, 6, and 9 months. After 12 months, a statistically significant difference was found between G3 and each of G1 and G2 where G3 showed significantly higher DMF scores (
< 0.
