Compressive Strength Evaluation of Three Distinct Implant Design Approaches.

Objectives: The study was done to assess the implant-abutment interface static compressive. strength of three design types and implant-abutment connection failure style. Materials and Methods: The implants at 306 with respect to the y-axis were aligned using a stainless steel holding device. Twenty specimens from each system totaled 60 total. A unidirectional vertical piston in a computer-controlled universal testing machine (MTS 810) generated static compression loading until failure. Specimens were macroscopically examined for fracture of the screw and implant, abutment looseness, and longitudinal displacement. Analysis of variance was used to analyze the data (ANOVA). Result: The screw-vent system had a mean compressive strength of 335.6 22.7 psi for the Unipost system, 384.3 37.1 psi for the screw-vent system, and 245.3 25.4 psi for the ITI-1 piece abutment connection. Conclusion: The connection between the Unipost implant and abutment showed a statistically significant variation.

Assessment of the Survival Rate of Short Dental Implants in Medically Compromised Patients.

AIM: To assess the survival rate of short dental implants in medically compromised patients. MATERIALS AND METHOD: This follow-up study was conducted on 342 medically compromised patients of both genders (580 dental implants). The failure rate of dental implants was assessed. RESULTS: There were 142 diabetes mellitus patients with 254 dental implants, 108 patients with hypertension with 190 dental implants, 26 patients with mental disabilities with 40 dental implants, 20 oral cancer patients with 36 dental implants, and 46 osteomyelitis subjects with 60 dental implants. There were 60 (10.5%) short dental implant (SDI) failures of which a maximum of 25 (22.7%) were seen with 4 mm diameter. Maximum failure was seen with osteomyelitis patients 8 (13.3%) followed by diabetes mellitus 32 (12.5%). Out of 270 dental implants in 130 control patients, implant failure was seen in 11 (4.07%). There was a significant (p < 0.05) bone loss on follow-up at 6 months, 1 year, and 2 years. CONCLUSION: Medically compromised patients are more prone to dental implant failure as compared to healthy subjects. CLINICAL SIGNIFICANCE: Since medically compromised patients are prone for implant failure, careful selection of cases is necessary.

Adjunctive Effect of Doxycycline with Conventional Periodontal Therapy on Glycemic Level for Chronic Periodontitis with Type 2 Diabetes Mellitus Subjects.

AIMS: This study aimed to assess the use of doxycycline in adjunct to periodontal therapy on the glycemic levels for chronic periodontitis patients with type 2 diabetes mellitus (DM). MATERIALS AND METHODS: Fifty-one diabetic subjects with chronic periodontitis were selected and randomly assigned into 3 groups with 17 subjects each. Scaling and root planing (SRP) was done in group I, SRP and doxycycline was given in group II, and group III did not receive any periodontal treatment till 3 months. Probing pocket depth (PPD), clinical attachment level (CAL), plaque index (PI), gingival index (GI), and metabolic parameters were evaluated at baseline (day 0) and after 3 months (day 90). The statistical analysis was carried out using SPSS 17.0 software with significance fixed at 95% CI (p < 0.05). RESULTS: The mean difference between baseline and day 90 for all periodontal parameters was significantly higher (p < 0.01) in group I and group II compared to control (group III). The metabolic parameters such as fasting plasma glucose (FPG), 2-hour postprandial plasma glucose (PPG), and glycated hemoglobin (HbA1c%) level were reduced in groups I and II compared to group III; however, only HbA1c% values were found significantly reduced (p < 0.01) at day 90. Group II showed significantly better metabolic parameters than group I at day 90. CONCLUSION: The adjunct of doxycycline to conventional periodontal therapy provides additional benefit in reducing glycemic level and improves periodontal health. CLINICAL SIGNIFICANCE: The prevalence of diabetes as well as periodontitis is increasing nowadays in the world. With treatment of periodontitis, it is found that there is reduction of glycemic level in diabetes. So it is an alert to health professionals about the relation of diabetes and periodontitis and so that they conduct a multidisciplinary treatment.

Effect of alcohol consumption status and alcohol concentration on oral pain induced by alcohol-containing mouthwash.

Alcohol exposure alters oral mucosa. Patient compliance with mouthwash use may be reduced by oral pain resulting from rinsing with alcohol-containing mouthwash. However, information regarding the effects of alcohol consumption and mouthwash alcohol concentration on oral pain is limited. In this double-blind, randomized, controlled cross-over study, we investigated the effects of alcohol consumption status and mouthwash alcohol concentration on response to and perception of oral pain induced by alcohol-containing mouthwash. Fifty healthy men aged 33 to 56 years were enrolled and classified as drinkers and nondrinkers according to self-reported alcohol consumption. All subjects rinsed with two commercially available mouthwash products (which contained high and low concentrations of alcohol) and a negative control, in randomized order. Time of onset of oral pain, time of cessation of oral pain (after mouthwash expectoration), and pain duration were recorded, and oral pain intensity was recorded on a verbal rating scale. Drinkers had later oral pain onset and lower pain intensity. High-alcohol mouthwash was associated with earlier pain onset and greater pain intensity. In addition, oral pain cessation was later and pain duration was longer in nondrinkers rinsing with high-alcohol mouthwash. In conclusion, alcohol consumption status and mouthwash alcohol concentration were associated with onset and intensity of oral pain.
