How could multimedia information about dental implant surgery effects patients' anxiety level?

BACKGROUND: To evaluate the effects of different patient education techniques on patients' anxiety levels before and after dental implant surgery. MATERIAL AND METHODS: Sixty patients were randomized into three groups; each contained 20 patients; [group 1, basic information given verbally, with details of operation and recovery; group 2 (study group), basic information given verbally with details of operative procedures and recovery, and by watching a movie on single implant surgery]; and a control group [basic information given verbally "but it was devoid of the details of the operative procedures and recovery"]. Anxiety levels were assessed using the Spielberger's State-Trait Anxiety Inventory (STAI) and Modified Dental Anxiety Scale (MDAS). Pain was assessed with a visual analog scale (VAS). RESULTS: The most significant changes were observed in the movie group (P < 0.05). Patients who were more anxious also used more analgesic medication. Linear regression analysis showed that female patients had higher levels of anxiety (P < 0.05). CONCLUSIONS: Preoperative multimedia information increases anxiety level.

The efficacy of hyaluronic acid in postextraction sockets of impacted third molars: A pilot study.

OBJECTIVE: This study aims to evaluate the effectiveness of local hyaluronic acid (HA) administration to surgically remove impacted third molar sockets and measure pain, swelling, and trismus. MATERIALS AND METHODS: The study included a total of 25 healthy patients aged 18-29 years with asymptomatic bilaterally impacted lower third molars. All cases have been performed under local anesthesia. In the study group, 0.8% HA (Gengigel®) was applied in the postextraction sockets of the right third molars and in the control group nothing was applied to the extraction sockets of the left third molars. Postoperative pain, trismus, and swelling were evaluated on the 1st, 3rd, and 7th postoperative days. RESULTS: No difference was determined between groups in facial swelling and maximum mouth opening. However, the amount of pain significantly reduced in HA groups according to visual analog scale (P = 0.001). CONCLUSION: The results of this study showed that HA can produce an analgesic action in postextraction sockets after surgical removal of impacted teeth and therefore it has a clinical benefit to reduce usage of nonsteroidal anti-inflammatory drugs after dentoalveolar surgery.

Effects of ozone therapy on pain, swelling, and trismus following third molar surgery.

The aim of this study was to evaluate the efficacy of therapeutic ozone application in the management of pain, swelling, and trismus associated with the surgical removal of impacted mandibular third molars. Sixty consecutive patients with asymptomatic bilateral impacted mandibular third molars were recruited into the study. Randomly, by use of envelops, the molar on one side was extracted and ozone therapy was given (study side); the molar on the other side was extracted 2 weeks later and sham ozone therapy was given (negative control side). The mean age of the 60 patients was 22.6±2.3 years (range 18-25 years). No differences were found between the two sides for mouth opening or swelling. The degree of pain and the number of analgesic tablets taken was significantly lower for the study side. This study showed ozone therapy to have a positive effect on OHIP-14 questionnaire results.

The role of MDR1 C3435T gene polymorphism on gingival hyperplasia in Turkish renal transplant patients treated with cyclosporine in the absence of calcium channel blockers.

OBJECTIVE: To investigate the occurrence of MDR1 C3435T gene polymorphisms in the Turkish renal transplant patients treated with cyclosporine (CsA), and correlate these findings with prevalence and degree of gingival hyperplasia (GH). METHODS: Before to renal transplantation, dental treatment and oral hygiene education of 300 renal disease patients was completed. Peripheral blood samples were collected from 154 renal transplant recipients on CsA treatment without calcium channel blockers. MDR1 C3435T gene polymorphism and GH were analyzed at posttransplant month 6. RESULTS: No difference was detected among groups for age, posttransplant period, creatine levels, serum concentration of CsA, or plaque and bleeding indices (P > .05). Out of all transplanted patients, 42.8% were found to have the heterozygote genotype. This was reduced to 37.5% when individuals with GH were taken into account. However, when degree of GH was analyzed, those with severe GH were found to have the heterozygote genotype significantly more often (P < .05). CONCLUSIONS: The MDR1 gene polymorphism is not associated with GH frequency, but may be associated with GH severity.
