 Abstract

The purpose of the present study was to clinically and histologically analyze the capacity of microfibrillar collagen to augment palatal donor soft tissue and to evaluate the augmented donor tissue clinically in root coverage procedures. The study comprised 10 patients, each with a defect of either Miller's Class I or II description, in whom the thickness of palatal donor soft tissue was deemed inadequate for a soft tissue grafting procedure. The palatal soft tissue was augmented with microfibrillar collagen, and the thickness was evaluated clinically and histologically at baseline and 2 months postoperatively. The augmented soft tissue was subsequently used for the management of gingival recession. All patients were seen periodically, and oral hygiene instructions were stressed at all appointments. Clinical parameters such as vertical recession, horizontal recession, and width of keratinized tissue were recorded at baseline, 1st month, 3rd month, and 6th month, and clinical attachment level and probing depth were recorded at baseline and 6th month. The data were analyzed using the Student paired t-test to compare pre- and post-surgery measurements. A statistically significant (P < 0.01) increase in the thickness of the soft tissue (1.244 ± 0.384 mm) was observed at two months. A statistically significant reduction in the depth of recession (3.20 ± 1.11 mm) was observed at 6 months. A statistically significant mean gain of 4.30 ± 1.34 mm was observed in the width of the keratinized tissue at 6 months. The Plaque Index remained low throughout the post-surgical period. The results of this study indicate that microfibrillar collagen has the potential to augment the palatal donor soft tissue, and the augmented tissue is stable and can be subsequently used for grafting procedures. ...Read More >>

 Ensuring a Successful Inferior Alveolar Nerve Block (IANB) in Endodontics: A Review of Current Concepts

 Abstract

The success of adequate anesthesia is one of the major factors in patient cooperation towards dental treatments that involve pain. Treatment performed under incomplete analgesia will compromise the quality of the dental procedure performed and the patient's confidence in the dentist. The most commonly used technique for anesthetizing the mandibular molar during various treatments is the Inferior Alveolar Nerve Block (IANB). However, failure of complete analgesia after IANB occurs frequently, regardless of experience. This review summarizes various factors and reasons responsible for such failures and discusses in detail how to overcome them by various supplemental aids and alternative techniques. Therefore, clinicians, instead of giving a second shot of IANB, can systematically evaluate the reason for failure and rectify it by newer techniques, thereby substantially improving outcomes. It is mandatory for successful dental practice to be familiar with recent advancements, the indications, complications of alternative techniques, and implementing them in day-to-day practice. ...Read More >>

 Abstract

Dental implants are widely used for the rehabilitation of edentulous edges and have shown a good success rate. However, the treatment becomes challenging when it comes to atrophic ridges. The rehabilitation of atrophic ridges with endosseous implants may pose a challenge in implant dentistry. Custom-made implants with immediate loading over-dentures are emerging as a solution for atrophic jaw rehabilitation. In this case report, a 67-year-old male patient with a partially edentulous maxilla and mandible reported to Edens Dental And Maxillofacial Hospital. The patient was treated using custom-made 3D printed subperiosteal titanium implants using a 2-stage approach. The results were good, but long-term studies using larger patient samples would be necessary to confirm the outcome. ...Read More >>

 Patient's Perception on Mini-Screwsused for Orthodontic Treatment

 Abstract

This study aimed to investigate the perspectives and overall experiences of patients who underwent orthodontic mini-implant procedures as part of their orthodontic treatment, from placement to removal. The objective was to assess the perspectives of patients who underwent mini-implant placement in their treatment and to compare the responses of different age groups and genders. A survey consisting of 10 questions was distributed among 28 patients who had undergone orthodontic treatment with mini-implants. Descriptive statistics, including frequency and percentages, were calculated. The statistical significance between gender and age group was assessed using Pearson's Chi-square test.The questions assessed the patients' overall experiences with mini-implants, including anxiety and pain levels, comparisons of pain with other dental procedures, and experiences during the initial 30 days after placement. The data were analyzed using IBM SPSS Statistics for Windows, Version 26.0. Based on the patients' responses, 64.3% of them felt anxious before the insertion of the mini-implant, with the majority being females (75%). The pain level during insertion and removal was reported to be mild to moderate, and 57.1% of patients compared the pain to be less than that of tooth extraction or root canal treatment. Men, however, reported feeling more pain and discomfort than females. The most common discomfort faced was irritation to the adjacent tissue, and overall, 89.3% of the respondents indicated that they would recommend mini-implants to others. Based on patient perspectives and experiences, it can be concluded that mini-implants are a viable and acceptable option in orthodontic treatment due to their minimal pain and less discomfort caused to the patients. ...Read More >>

 Abstract

The aim of this study was to evaluate the surface roughness and wear resistance of light-cured composite coating materials on acrylic and composite denture teeth. Surface coatings on denture teeth are given for esthetic reasons but can be affected by the dynamic oral conditions, given the thin nature of their application. Twenty disc-shaped specimens were prepared of standard size from the largest available incisor size of composite and acrylic resin denture teeth of shade A2. The specimens were grouped into Group 1 (composite resin denture teeth) and Group 2 (acrylic resin denture teeth). The surface roughness value before and after the application of the light-cured composite coating was evaluated using a Profilometer. Wear testing was performed by subjecting the specimens to simulated tooth brushing, and mass loss values were calculated. Statistical analysis was performed using Independent t-test and Paired t-test for inter and intra-group comparison. The mean surface roughness of Group 1 before and after coating was 3.0818 µm ± 0.2275 µm (p=0.04), and that of Group 2 was obtained as 2.2952 µm and 0.2360 µm, respectively (p<0.001). Group 1 showed less wear compared to Group 2 on wear analysis through the mass loss value. Although there was a difference in the values observed between the groups, they were statistically insignificant. The surface roughness and wear resistance of composite denture teeth were better compared to acrylic resin denture teeth upon the application of the light-cured coating material. ...Read More >>
