RESUMEN
Background: Dental implants are considered better, latest, and most advanced technique of teeth replacement in present times with more teeth loss and increased related concerns. Aims: The present clinical trial was carried out to assess marginal bone loss and implant failure in immediate and delayed loading implants. The study also evaluated healing using Polymerase Chain Reaction (PCR) and the effect of risk factors on marginal bone loss. Materials and Methods: The 44 subjects were randomly divided into two groups with immediate loading and delayed loading protocols. Various soft-tissue parameters were seen clinically. Quantitative PCR was done to detect biomarkers. The collected data were subjected to statistical evaluation with a level of significance at P < 0.05 and the results were formulated. Results: Concerning marginal bone loss, it was seen that for delayed loading, the bone loss at the implant level was 1.52 ± 0.14, 0.19 ± 0.11, and 0.40 ± 0.12, respectively, at placement, 1 and 2 years. Plaque and mucosal bleeding scores were low at the time of placement with respective values of 0.96 ± 0.12 and 28.42 ± 3.15 for the delayed loading group and 0.98 ± 0.11 and 30.24 ± 3.15 for the immediate loading group. Tartrate-resistant acid phosphatase (TRAP) showing remodeling was high at 3 months in delayed loading (13.3 ± 8.5). Alkaline Phosphatase (ALP) was highest in delayed loading at 3 months (25.2 ± 7.7) and immediate loading at 2 days (32.6 ± 13). Conclusion: Both immediate loading and delayed loading implants show similar results in terms of bone loss, soft-tissue parameters, and biomarkers in sulcular fluids with relatively few and manageable complications.
RESUMEN
BACKGROUND: Oral cancer is a preventable disease that can be controlled by tobacco cessation and health education. For development of a healthy nation, a healthy society is desirable that is dependent on physically and mentally strong adolescents and adults. OBJECTIVES: The present study was conducted to assess the effectiveness and utilization of a structured instructional module on knowledge, attitude, and practice regarding the prevention of oral cancer among adolescents. MATERIALS AND METHODS: The study was conducted on 500 preuniversity urban college students, divided into two groups: experimental and control groups (n = 250 each). A structured instructional module was developed and knowledge, attitude, and practice of students were analyzed. Pre and post values for all parameters were taken and subjected to statistical analysis using SPSS software version 20.0. RESULTS: The data were collected and compared for sociodemographic variables and knowledge, attitude, and practice of students for prevention of oral cancers. A statistically significant correlation was observed between all the parameters for both the groups. In the experimental group, a significant correlation (P ≤ 0.05) was observed between pre- and posttest values for knowledge, attitude, and practices for prevention of oral cancers. CONCLUSION: It has been observed that there are several implications of the structured instructional module in the field of education, practice, administration, and research.
RESUMEN
BACKGROUND: Smoking impose various ill-effects on the alveolar bone concerning dental implants including reduced bone height, delayed healing of bone, poor peri-implant bone formation, increased bone loss, and peri-implantitis. AIMS: The present clinical trial was aimed to analyze the smoking effect on dental implant survival rate as well as marginal bone loss in dental implants. MATERIALS AND METHODS: Out of 86 patients, Group I had 43 patients who were smokers and Group II had nonsmokers. Following the implant placement, marginal bone loss radiographically and mobility were assessed clinically at 3, 6, and 12 months after implant loading. RESULTS: The mean marginal loss seen in smokers at 3 months was 2.13 ± 0.21, 2.46 ± 0.09, 2.60 ± 0.0.92, and 2.74 ± 0.11 for maxillary anterior, maxillary posterior, mandibular anterior, and mandibular posterior regions, respectively. The 12-month recall visit showed a higher proportion of smokers having implant mobility. In smokers, 13.95% (n = 6) of the study participants had implant mobility, whereas 6.97% (n = 3) of the nonsmokers had mobility. CONCLUSION: Smoking is associated with long-term implant failure which is directly proportional to the duration ad frequency of smoking. Furthermore, smoking has a detrimental effect on dental implants and its surrounding bone.
RESUMEN
BACKGROUND: The alveolar process is a tooth-dependent structure, and hence, removal of teeth results in the alteration of alveolar process. To alter bone remodeling after dental extraction, various techniques have been put forward for ridge preservation. AIM: The aim of this study is to evaluate and compare the changes of hard and soft tissues in postextraction socket after the application of bone graft material. MATERIALS AND METHODS: Healthy patients of sample size of 40 were selected who underwent the extraction of anterior tooth irrespective of the arch, from premolar of one side to another, with the exception of incisors in mandible. Twenty patients were randomly selected as the control group and other 20 as the experimental group using an allograft bone material, i.e., beta-tricalcium phosphate to fill the socket. Cone-beam computed tomography (CBCT) was done as baseline preoperative and postoperative at 14 weeks after the extraction. CBCTs data help in recording linear and volumetric measurements which was performed by calibrated examiners to record all the measurements. After measurements, digital planning of dental implants was performed. RESULTS: Forty participants were selected, in which 20 patients each were as the experimental and control groups. No significant difference was found at basal line at any of the cases. At follow-up of 14 weeks, statistical significance was seen in buccal and lingual plate height in the experimental group, and no significant difference was seen in the control group.(P = 0.023). CONCLUSIONS: This study clearly points out that an alveolar ridge preservation technique provides therapeutic benefit by limiting bone resorption in comparison to extraction alone.
RESUMEN
BACKGROUND: Immediate loading of dental implants is an obvious advantage. A long treatment period that involves the wearing of a temporary prosthesis may be of great inconvenience, and is sometimes the reason for not choosing implant-supported restorations at all. AIM: In our study, an attempt was made to immediately load single tooth implants in the aesthetic zone of the dentition. MATERIALS AND METHODS: Patients were selected from Government Dental College, Patna. Twenty-four single tooth implants were placed in 24 patients; 12 male and 12 female patients desiring replacement of one or more missing teeth in anterior region were selected. Surgery for the placement of the implant was carried out, and implants of the Uniti Implant System were placed. The abutment was then attached and the flap was sutured. A temporary acrylic resin crown was fabricated and cemented on the same day. Permanent prosthesis was inserted on sixth month after implant placement. RESULTS: A clinical study was performed to evaluate the treatment outcomes of dental implants installed according to a one-stage surgical procedure followed by immediate loading with prosthesis. Of the 24 implants, 23 showed signs of successful osseointegration over a 1-year follow-up. CONCLUSION: Within limits of the evaluated data, it was observed that immediately loaded implants osseointegrate, so this alternative was used over conventional procedures that take 6 months for osseointegration. This has advantages, both for patient and practitioner.
RESUMEN
Facial disfigurement due to trauma is very common as the face is a prominent part of the body and is susceptible to injuries. A protocol for the diagnosis and intervention for psychological problems of trauma patients should be implemented in the Indian hospitals as they lack policies for assessing the mental status of such patients. This study was conducted to analyze and determine the psychological implications and need for mental health services of maxillofacial trauma patients. Fifty patients with maxillofacial trauma above 18 years of age were included in this study. The assessment was done using the Hospital Anxiety and Depression Scale (HADS) and Trauma Screening Questionnaire (TSQ), which are considered as the standard tools for assessment of psychological disorders post-trauma. We observed psychological stress in 84% of the patients at the baseline, which reduced to 24% after one month at the first follow-up visit and further reduced to 22% at the second follow-up visit. The reduction in the percentage from the first to the second follow-up visit was less significant. However, the change in HADS and TSQ scores was found to be significant, suggesting that the intensity of trauma decreases with the time-lapse. Anxiety, depression, and post-traumatic stress are prevalent in patients with maxillofacial trauma, which may lead to impaired day-to-day life. Our results suggest that there is a need for psychological care in patients with maxillofacial trauma.
