Tratamento com implantes dentários pós-extração.

Introduction: The aim of the present study was to show the results of treatment with dental implants inserted immediately after extraction. Methods: 22 patients with unitary, partial or total tooth loss were treated with 82 Microdent ® implants with etched and acid-etched surfaces. All implants were inserted immediately after the corresponding extraction. The implants were loaded after a healing period of 3 months in the mandible or 6 months in the upper mandible. Results: Clinical findings indicate survival and implant success of 97.6%. 2 implants were lost during the healing period. 73.2% of the implants were inserted in the  maxilla, while 26.8% in the mandible. After an average functional load period of 12 months, there were no late complications. Conclusions: This study indicates that dental implants inserted immediately after extraction can be a predictable and successful alternative to the implant.  Introdução: O objetivo do presente estudo foi mostrar os resultados do tratamento com implantes dentários inseridos imediatamente após a extração. Métodos: 22 pacientes com perda dentária unitária, parcial ou total foram tratados com 82 implantes Microdent ® com superfície tratada com ácidos. Todos os implantes foram inseridos imediatamente após a extração correspondente. Os implantes foram carregados após um período de cicatrização de 3 meses na mandíbula ou 6 meses na maxila. Resultados: Os achados clínicos indicam sobrevivência e sucesso dos implantes de 97,6%. 2 implantes foram perdidos durante o período de cicatrização. 73,2% dos implantes foram inseridos na maxila, enquanto 26,8% na mandíbula. Após um período médio de carga funcional de 12 meses, não houve complicações tardias. Conclusões: Este estudo indica que implantes dentários inseridos imediatamente após a extração podem ser uma alternativa previsível e bem-sucedida ao implante

The Effects of Two Planning Interventions on the Oral Health Behavior of Iranian Adolescents: A Cluster Randomized Controlled Trial.

PURPOSE: The aim of this study was to investigate the effectiveness of a planning intervention (specifying when, where, and how to act) and an implementation intention intervention (specifying the same in the format of an if-then plan) in increasing self-reported brushing in adolescents. METHODS: The study adopted a cluster randomized controlled trial design, and 1158 students in 48 schools were randomized to planning, implementation intention, or active control conditions. After baseline assessment, all participants received a leaflet containing information and recommendations on oral health and instructions on correct brushing behavior. After reading the leaflets, they were provided with a toothbrush and toothpaste plus a calendar in which to record their brushing. Participants in the planning condition and in the implementation intention condition also received instructions to form specific plans regarding brushing behavior. Self-reported brushing, perceived behavioral control, self-monitoring, intention, frequency of planning, oral health-related quality of life, and dental plaque and periodontal status were measured 1 and 6 months later. RESULTS: Both intervention conditions showed a significant improvement in the frequency of self-reported brushing, self-monitoring, frequency of planning, intention, perceived behavioral control, plaque index, periodontal health, and oral health-related quality of life compared to the control condition at both follow-ups. Comparing the two intervention conditions revealed that adolescents who received the implementation intention intervention had significantly greater improvement in the frequency of self-reported brushing, intention, frequency of planning, and periodontal health than those in planning condition. CONCLUSIONS: Taken together, the findings suggest that forming implementation intentions as well as planning has the potential to increase dental self-reported brushing rates in adolescents, but that forming implementation intentions has the strongest impact on dental hygiene behavior and is, therefore, recommended. TRIAL REGISTRATION NUMBER: The trial was registered with the ClinicalTrials.gov database (NCT02066987) https://www.clinicaltrials.gov/ct2/show/NCT02066987

Improving Oral Hygiene Skills by Computer-Based Training: A Randomized Controlled Comparison of the Modified Bass and the Fones Techniques

Background: Gingivitis and other plaque-associated diseases have a high prevalence in western communities even though the majority of adults report daily oral hygiene. This indicates a lack of oral hygiene skills. Currently, there is no clear evidence as to which brushing technique would bring about the best oral hygiene skills. While the modified Bass technique is often recommended by dentists and in textbooks, the Fones technique is often recommended in patient brochures. Still, standardized comparisons of the effectiveness of teaching these techniques are lacking. Methodology/Principal Findings: In a final sample of n=56 students, this multidisciplinary, randomized, examiner-blinded, controlled study compared the effects of parallel and standardized interactive computer presentations teaching either the Fones or the modified Bass technique. A control group was taught the basics of tooth brushing alone. Oral hygiene skills (remaining plaque after thorough oral hygiene) and gingivitis were assessed at baseline and 6, 12, and 28 weeks after the intervention. We found a significant group×time interaction for gingivitis (F(4/102)=3.267; p=0.016; e=0.957; ?2=0.114) and a significant main effect of group for oral hygiene skills (F(2/51)=7.088; p=0.002; ?2=0.218). Fones was superior to Bass; Bass did not differ from the control group. Group differences were most prominent after 6 and 12 weeks. Conclusions/Significance: The present trial indicates an advantage of teaching the Fones as compared to the modified Bass technique with respect to oral hygiene skills and gingivitis. Future studies are needed to analyze whether the disadvantage of teaching the Bass technique observed here is restricted to the teaching method employed.
