Comparative Assessment of Three Different Alveolar Ridge Dimension Measurement Methods before Implant Placement: An In Vivo Study.

AIM: The purpose of this study was to compare the three various techniques for measuring the alveolar ridge's dimensions prior to implant insertion. MATERIALS AND METHODS: For this study, a total of 36 participants were chosen. To prepare a surgical stent, a study model was created from an alginate impression. A first point (reference point) was marked on the crest of the ridge in relation to the adjacent teeth. Then, one point (point 1) and another point (point 2) were marked at distances of 3 and 6 mm, respectively, from the reference point. Based on the procedure for measuring the size of the alveolar ridge, the study was divided into the following groups. Group I: Cone-beam computed tomography (CBCT) measurement method; Group II: Ridge mapping measurement method; Group III: Direct caliper measurements method. Descriptive statistics were used to estimate the mean and standard deviation (SD). The Student's unpaired t-test was utilized for the statistical analysis. The 5% level of significance was used. RESULTS: There was no significant difference found between CBCT with ridge mapping and direct caliper measurements. However, on comparison of ridge mapping and direct caliper measurements technique, at point 1, the ridge mapping was 3.88 ± 0.12 and the direct caliper measurement was 3.62 ± 0.08. At point 2, the ridge mapping was 6.58 ± 0.06 and the direct caliper measurement was 6.32 ± 0.04. There was a statistically significant difference found between these two measurement methods. CONCLUSION: Within the limitation, the current study came to the conclusion that when CBCT and ridge mapping measurements were individually compared with the gold standard-the surgical open method, CBCT-demonstrated to be a highly specific and sensitive method for detecting the residual alveolar ridge width in the treatment planning of dental implants. CLINICAL SIGNIFICANCE: Evaluation of alveolar bone is necessary during treatment planning for dental implant placement. Using simply panoramic and/or periapical radiographs to evaluate the bone may not be sufficient because it only provides two-dimensional information regarding the implant locations. Therefore, for better implant placement, three-dimensional information of the implant site, such as CBCT and ridge mapping technique, should be assessed.

Assessment of the Impact of Commonly used Beverages on Durability of Suture Materials: An In Vitro Study.

Aim: The current study was conducted to evaluate the influence of frequently ingested beverages on the stability of suture materials. Materials and Methods: This research comprised of two kinds of chromic catgut, polyglactin 910 (4-0) absorbable suture materials. Every specimen was subjected to tying using a square surgeon's knot. Subsequent to pretensioning, 80 suture samples (40 of every material) were employed in this research. Every specimen was subjected to immersion in artificial saliva to replicate the oral atmosphere. Specimens were sunken in the acidic drink (Coca Cola) and tea for 10 min every day. Tensile strengths of the suture specimens were subjected to test at particular time periods: before immersion and 1, 7, and 14 days after immersion. Tensile strength evaluation of the suture specimens was performed employing the microtensile tester at a cross-head speed of 2.0 mm/60 s. Results: When subjected to exposure to acidic beverages, the tensile strength of chromic catgut suture before immersing was 25.14 ± 0.16, 25.02 ± 0.08 on the first day, 16.34 ± 0.23 on the seventh day, and 9.18 ± 0.28 on the fourteenth day. When the suture substance made contact with tea, the tensile strength before immersing was 24.48 ± 0.02, 24.14 ± 0.16 on the first day, 18.26 ± 0.11 on the seventh day, and 12.39 ± 0.14 on the fourteenth day. When subjected to exposure to acidic beverages, the tensile strength of polyglactin 910 sutures before immersing was 25.21 ± 0.02, 25.08 ± 0.01 on the first day, 18.12 ± 0.06 on the seventh day, and 10.06 ± 0.32 on the fourteenth day. When the suture substance made contact with tea, the tensile strength before immersing was 25.02 ± 0.14, 24.96 ± 0.04 on the first day, 20.48 ± 0.18 on the seventh day, and 14.10 ± 0.08 on the fourteenth day. The differences between the groups were statistically significant. Conclusion: In conclusion, polyglactin 910 exhibited a maintained strength superior than chromic catgut sutures subsequent to 14 days.

Assessment of Oral Health-Related Quality of Life in Patients Receiving Corticobasal Dental Implants.

Background: Among various treatment modalities for tooth replacement, dental implants are considered the best one. This study assessed the effects of smoking, periodontitis, and diabetes on oral health-related quality of life (OHRQoL) in patients receiving corticobasal dental implants. Materials and Methods: One hundred twenty patients of either gender who received corticobasal dental implants were enrolled. All were subjected to Oral Health Impact Profile-20 (OHIP-20) for dental implant patients (OHRQoL questionnaire). The patient satisfaction level was measured on a scale with points ranging from 0 to 5. The value 0 indicates no satisfaction, whereas the value 5 shows highly satisfied. Results: Of 120 patients, males were 70 and females were 50. The overall satisfaction level was 4.92, articulation speech was 4.12, implants were 4.80, and construction was 4.88. The overall satisfaction, articulation speech, implants, and construction values in patients with and without diabetes were 4.90 vs 4.93, 4.56 vs 4.86, 4.76 vs 4.92, and 4.94 vs 4.83, respectively. The overall satisfaction, articulation speech, implants, and construction values in patients with and without smoking were 4.83 vs 4.91, 4.52 vs 4.88, 4.70 vs 4.82, and 4.12 vs 4.84, respectively. The overall satisfaction, articulation speech, implants, and construction values in patients with and without periodontitis were 4.72 vs 4.96, 4.52 vs 4.88, 4.73 vs 4.98, and 4.81 vs 4.95, respectively. The overall satisfaction, articulation speech, implants, and construction values in patients with one to three risk factors and control were 4.85 vs 4.96, 4.82 vs 4.94, 4.88 vs 4.97, and 4.76 vs 4.86, respectively. There was a significant difference in pain, infections and/or swelling, sleeping problems, problems with self-confidence, taste, chewing discomfort and/or difficulties, and influence on food choice before and after in patients treated with corticobasal dental implants (P < 0.05). Conclusion: The satisfaction level is higher after obtaining corticobasal dental implants in patients with diabetes, smoking, and periodontitis as compared to control. Thus, corticobasal dental implants may be considered alternate treatment options for these patients.

Assessment of Self-medication Practices among Nonteaching Faculty in a Private Dental College - A Cross-sectional Study.

Background: Self-medication is the use of nonprescription drugs to treat a disease by an individual. Amid the looming COVID-19 scenario in our country, wherein universal access to health care is not yet fully established, self-medication can lead to serious effects like antimicrobial resistance and is a matter of public health concern. Aim: The aim of the present study was to assess the self-medication practices among the nonteaching faculty in a private dental college in Mangaluru, India. Materials and Methods: The cross-sectional study was conducted for a duration of 6 months. All the nonteaching faculty employed in AB Shetty Memorial Institute of Dental Sciences were included in the study employing the total enumeration sampling technique. A total of 57 participants were included in the study. Ethical clearance was obtained from the Institutional Ethical Committee. The participants not providing consent were excluded from the study. The data were obtained using a validated pretested self-administered questionnaire in Kannada language. The collected data were analyzed using SPSS version 23 for descriptive and inferential statistics. Results: Around 50.8% of the participants often or regularly self-medicated. Males were found to practice self-medication higher than females, and this difference was found to be statistically significant (χ 2 = 11.088, P = 0.001). The most common reason cited for self-medication was that it was less costly (37, 64.9%). Doctors at the workplace (35, 61%) were the most common source of information. The most frequent symptoms provoking self-medication were aches in any body parts (32, 56.1%). The drugs most frequently consumed were analgesics (33, 57.9%), and 28 (49.1%) participants disagreed that self-medication was a safe practice. Conclusion: Our findings suggest that the prevalence of self-medication was high among the study participants and it is an alarming situation. A holistic approach must be initiated at the grassroots level which would involve health promotion initiatives such as awareness campaigns and regulatory policies to tackle the implications of self-medication.

Assessment of Root Dentin Defect during Retreatment Procedure using Various NiTi Hand and Rotary Retreatment Files: An In vitro Study.

Aim: The aim of the current study was to evaluate the radicular dentin defect during retreatment employed diverse NiTi hand and rotary retreatment file systems. Materials and Methods: Eighty mandibular premolars with a single root and root canal that were recently extracted were gathered and stored. The premolars were subject to decoronation at cementoenamel junction (CEJ) beneath irrigation with water to attain a uniform radicular length of 16 mm. Gutta-percha cones were covered with sealer and introduced into the root canal up to the working length. Eighty teeth were allocated at random into four groups with each group consisting of 20 samples. Group I: Control, Group II: EdgeFile XR retreatment rotary files, Group III: ProTaper Universal retreatment files, and Group IV: MTwo retreatment files. Under constant water cooling, the roots were cut flat with a diamond disc at apical third (3 mm), middle third (6 mm), and cervical third (9 mm) points. Stereomicroscope was employed to visualize the sections below × 20 magnification. Results: A statistically significant difference was noted among the groups with respect to the formation of radicular dentinal defects at 3 mm (P < 0.01) and 6 mm (P < 0.001), while the sections at 9 mm did not exhibit any statistically significant difference (P > 0.598). Conclusion: Despite the limitations in this study, it was concluded that all the evaluated file systems efficiently eliminated root canal filling during the retreatment. In addition, it was noted that the EdgeFile XR group exhibited fewer root dentin defects in comparison with the MTwo and ProTaper Universal group of files.
