RESUMEN
BACKGROUND: The aim of this study was to analyze the correlation between the dental plaque indices measured using quantitative light-induced fluorescence-digital (QLF-D) and conventional clinical indices that assess gingival status. METHODS: From among the patients who visited Ewha Womans University Mokdong Hospital, 33 adults in their 20s who had relatively even teeth were selected for full-mouth QLF-D imaging. The images were used to analyze the QLF-D score and the QLF-D ΔR score. As clinical indices, the gingival index (GI), bleeding on probing (BOP), probing pocket depth (PPD), and patient hygiene performance (PHP) index were measured. The correlations between the QLF-D score and QLF-D ΔR score and each clinical index were analyzed. Analyses were performed comparing the indices of maxillary and mandibular teeth, the teeth on right and left sides of the mouth, anterior and posterior teeth, and buccal and lingual surfaces of each tooth. Pearson's correlation analysis was conducted (p < 0.05). RESULTS: The mean full-mouth QLF-D score was highly correlated with the GI, BOP, PPD, PHP index (p < 0.01). The mean full-mouth QLF-D score showed the highest correlation with GI (r = 0.749) and the lowest correlation with PPD (r = 0.683). The correlations between the QLF-D score were higher in the mandible than in the maxilla and in the anterior teeth than in the posterior teeth, while no significant differences were seen between the buccal and lingual surfaces of tooth. CONCLUSIONS: This study concluded that the correlations between the plaque indices measured for each tooth surface area using QLF-D and the clinical indices assessed were significantly high, and it allowed objective determination of the gingival status. Therefore, the plaque index measured using QLF-D may be used as an alternative to supplement the shortcomings of conventional clinical indices for educating patients about plaque control and continued patient oral care.

The aim of this randomized-controlled, single-blinded study was to compare the effects of mechanical tooth cleaning (MTC) and ultrasonic debridement (UD) on oral hygiene status in healthy young adults. Thirty-seven participants (mean age: 20.3±0.62 years) were divided into 3 groups after pre-examination: group A, receiving MTC; B, receiving MTC+UD using a universal insert (UDUI); and C, receiving MTC+UD using a probe-shaped insert (UDPI). All participants were required to abstain from oral hygiene for 24 hours after the allocated intervention, after which they were examined. A masked examiner determined the Quigley-Hein plaque index (PlI) and Silness and Löe gingival index (GI) scores before the interventions and after 24 hours of non-brushing. A significant increase in the PlI score was observed in group A (p<0.001) in comparison with that in group B (A: 0.311±0.26; B: -0.01±0.33; C: 0.13±0.27; p<0.05). A significant decrease in the GI score was observed in groups B and C (p<0.05), and the change in this score in group C significantly differed from that in group A or B (A: -0.04±0.25; B: -0.13±0.17; C: -0.33±0.2; p<0.05). Only MTC was insufficient to prevent plaque formation over a 24-hour period of non-brushing and decrease the GI score. Ultrasonic debridement was more effective in preventing plaque formation and decreasing the GI score, regardless of the type of insert used. The present results suggest that UD should be included as an important procedure in the provision of professional oral prophylaxis and that UDPI is as efficient for cleaning as UDUI.

UNLABELLED: Periodontal disease ranges from gingival inflammation (gingivitis) to the inflammation and loss of tooth-supporting tissues (periodontitis). Previous research has focused mainly on subgingival plaque, but supragingival plaque composition is also known to be associated with disease. Quantitative modeling of bacterial abundances across the natural range of periodontal severities can distinguish which features of disease are associated with particular changes in composition. We assessed a cross-sectional cohort of 962 Malawian women for periodontal disease and used 16S rRNA gene amplicon sequencing (V5 to V7 region) to characterize the bacterial compositions of supragingival plaque samples. Associations between bacterial relative abundances and gingivitis/periodontitis were investigated by using negative binomial models, adjusting for epidemiological factors. We also examined bacterial cooccurrence networks to assess community structure. The main differences in supragingival plaque compositions were associated more with gingivitis than periodontitis, including higher bacterial diversity and a greater abundance of particular species. However, even after controlling for gingivitis, the presence of subgingival periodontitis was associated with an altered supragingival plaque. A small number of species were associated with periodontitis but not gingivitis, including members of Prevotella, Treponema, and Selenomonas, supporting a more complex disease model than a linear progression following gingivitis. Cooccurrence networks of periodontitis-associated taxa clustered according to periodontitis across all gingivitis severities. Species including Filifactor alocis and Fusobacterium nucleatum were central to this network, which supports their role in the coaggregation of periodontal biofilms during disease progression. Our findings confirm that periodontitis cannot be considered simply an advanced stage of gingivitis even when only considering supragingival plaque. IMPORTANCE: Periodontal disease is a major public health problem associated with oral bacteria. While earlier studies focused on a small number of periodontal pathogens, it is now accepted that the whole bacterial community may be important. However, previous high-throughput marker gene sequencing studies of supragingival plaque have largely focused on high-income populations with good oral hygiene without including a range of periodontal disease severities. Our study includes a large number of low-income participants with poor oral hygiene and a wide range of severities, and we were therefore able to quantitatively model bacterial abundances as functions of both gingivitis and periodontitis. A signal associated with periodontitis remains after controlling for gingivitis severity, which supports the concept that, even when only considering supragingival plaque, periodontitis is not simply an advanced stage of gingivitis. This suggests the future possibility of diagnosing periodontitis based on bacterial occurrences in supragingival plaque.

OBJECTIVE: The main aim of this study was to develop a simplified quantitative denture plaque index that could help dentists to motivate denture patients to maintain optimal oral hygiene. The secondary aim was to assess specific areas of dentures more prone to accumulate plaque and subjects' oral hygiene habits related to their dentures. METHODS: One hundred subjects who wore maxillary and/or mandibular complete dentures for at least one year were included in the study as a powered sample. Fifteen females and 85 males, age range 45-75 years, were recruited. The study was carried out at King Saud University (KSU), College of Dentistry. A plaque disclosing solution was used to assess the plaque covered areas of denture. A quantitative percentage (10 x 10%) score index was developed by assessing plaque scores from digital images of intaglio surfaces of the dentures. The weighted kappa method was used to assess inter-examiner agreement in the main study. RESULTS: The new denture plaque index was identified as ASKD-DPI (Almas, Salameh, Kutkut, and Doubali-Denture Plaque Index). It ranged from 0 - 100%, and reflected the percentage of the intaglio surfaces of maxillary and mandibular complete dentures that contained plaque. It also classified quantitative percentages: 30 subjects ranged from 0 - 30% (low DPI), 50 subjects ranged from 31 - 70% (moderate DPI), and 20 subjects ranged from 71 - 100% (high DPI) denture plaque score. CONCLUSIONS: A simplified denture plaque index (ASKD-DPI) technique was developed and tested in this study. ASKD-DPI may be used for evaluating denture plaque scores, monitoring denture hygiene, and measuring compliance of patients regarding plaque control for complete dentures.

The aim of this study was to investigate the effect of a daily intake of probiotic lactobacilli on the prevalence and counts of oral Candida in frail elderly patients living in nursing homes. The study had a double-blind randomized placebo-controlled design with 2 parallel arms. The study group consisted of 215 older adults (range, 60 to 102 y) who were enrolled after informed consent. After baseline examination and randomization, the subjects were given 1 lozenge containing 2 strains of the probiotic bacterium Lactobacillus reuteri (DSM 17938 and ATCC PTA 5289) or placebo twice daily (morning and evening). The intervention period was 12 wk, and saliva and plaque samples were collected at baseline and follow-up. The primary end point was prevalence of high Candida counts assessed from chairside tests. Secondary end points were levels of dental plaque and gingival inflammation. The groups were balanced at baseline. The attrition rate to follow-up was 19%. There was a statistically significant reduction in the prevalence of high Candida counts in the probiotic group but not in the placebo group, and the difference was statistically significant in both saliva and plaque (P < 0.05). No significant differences between the groups were noted concerning the levels of supragingival plaque or bleeding on probing. Thus, daily use of probiotic lozenges may reduce the prevalence of high oral Candida counts in frail elderly nursing homes residents (ClinicalTrials.gov NCT02391532).

Research has demonstrated the validation of specific caries risk assessment (CRA) systems, but little is known about how dental practitioners assign a caries risk level to their patients. The aim of this study was to explore dental students' decision making in caries risk assignment when using the Caries Management By Risk Assessment (CAMBRA) system. Multiple correspondence analysis and chi-squared automated interaction detector analysis were performed on data collected retrospectively for a period of six years (2003-09) at the University of California, San Francisco predoctoral dental clinic. The study population consisted of 12,952 patients from six years of age through adult who received a baseline CRA during the period, were new to CAMBRA, and had not received any prior CAMBRA recommendations. The results showed variation in decision making and risk level assignment, illustrated by the range of percentages for the three scores (low, moderate, and high/extreme caries risk) when CRA was assigned for the first time. For those first-time CRAs, decision making was mainly based on four factors: cavities or caries lesions into dentin on radiograph, restorations during the last three years due to caries, visible heavy plaque, and interproximal lesions into enamel (by radiographs). This study's findings provide important data regarding one group of CAMBRA users and thus contribute to the development of knowledge about the implementation of caries risk assessment in contemporary dental practice.

AIM: To develop a socio-dental impact locus of control scale (SILOC) and to study its relationship with oral health status as well as dental attendance. STUDY DESIGN: Observational cross-sectional study design. METHOD: A seven-item SILOC scale based on locus of control and the WHO international classification of diseases' criteria for "Disability" in relation to oral health was developed. In the pilot study, 100 adolescent school children returned completed forms containing the multidimensional health locus of control (MHLC) and the (SILOC) scale. After confirmation of reliability and validity, 509 adolescent school children returned completed SILOC questionnaires and were examined for caries, plaque and gingivitis. A history of postponement of needed dental treatment was also elicited. RESULTS: The SILOC scores were highly correlated with the MHLC scores. Factor analysis revealed a two-factor solution accounting for 59 % of the variance. A Cronbach's alpha of 0.75 showed its internal consistency. Those with higher SILOC scores had greater levels of caries, plaque, gingivitis, and a history of postponing needed dental visits. Multiple logistic regression analysis after adjusting for potential confounders showed that those with high SILOC scores were more likely to have caries (OR = 3.32, p < 0.001), plaque (OR = 1.83, p = 0.026), gingivitis (OR = 1.80, p = 0.012) and a history of 'Postponement of needed dental treatment' (OR = 4.5, p < 0.001) as compared with the others. CONCLUSIONS: The SILOC scale showed satisfactory reliability and validity in measuring locus of control orientation in an Indian adolescent population.

RESUMO O fator mais importante na manutenção da saúde periodontal é o adequado controle do biofilme dentário. Face às dificuldades no controle mecânico por parte dos pacientes, métodos alternativos ou complementares têm sido utilizados como coadjuvantes químicos do controle do biofilme, auxiliando no tratamento da gengivite. Dentre esses métodos alternativos, destaca-se a fitoterapia, através da utilização de plantas medicinais. Dessa forma, esse estudo faz uma revisão sistemática tendo como objetivo a busca, na literatura atual, de estudos que comprovem a eficácia de produtos fitoterápicos à base de aroeira no controle do biofilme dental auxiliando no tratamento da gengivite. Foi realizada busca computadorizada nos indexadores MedLine, Lilacs, BBO e Scielo no período de Setembro a Outubro de 2014. Os descritores de pesquisa utilizados foram “biofilme”, “gengivite”, “aroeira”, “plantas medicinais” e “fitoterápicos”, bem como seus correspondentes em língua inglesa. Através dos descritores utilizados, foram encontrados 54 artigos. Após a aplicação dos critérios de inclusão e exclusão, chegou-se a 08 artigos: 05 revisões, 01 estudo clínico randomizado, 01 estudo experimental e 01 estudo observacional descritivo. De acordo com os estudos analisados, a aroeira apresentou atividades antifúngica e antimicrobiana eficazes, bem como potencial efeito de redução do índice de sangramento gengival, o que justifica seu uso no tratamento da gengivite.
ABSTRACT The most important factor to keep periodontal health is proper control of biofilm. Given the difficulties in the mechanical control by patients, alternative or complementary methods have been used as chemical supporting of biofilm control, helping the treatment of gingivitis. Among these alternatives, there is the phytotherapy, through the use of medicinal plants. Thus, this study it is a systematic review and aims to seek, in the current literature, researches proving the effectiveness of aroeira herbal products in the control of dental biofilm, assisting in the treatment of gingivitis. A computerized search was conducted in Medline, Lilacs, Scielo and BBO, from September to October of 2014. The search words used were “biofilm”, “gingivitis”, “aroeira”, “herbal medicines” and “phytotherapics” in Portuguese and English language. Through this method, 54 articles were found. After applying the inclusion and exclusion criteria, the research reached 08 items: 05 reviews, 01 randomized clinical trial, 01 experimental study and 01 descriptive observational study. According to the analyzed papers, the aroeira demonstrated effective antifungal and antimicrobial activities, as well as a potential reduction impact on gingival bleeding index, which would justify its use in the treatment of gingivitis.

PURPOSE: The aim of this randomised controlled trial was to assess the clinical performance of single crowns in the posterior maxilla supported by either 6-mm or 11-mm implants combined with maxillary sinus floor elevation. MATERIALS AND METHODS: 41 consecutive patients with one missing premolar or molar in the posterior maxilla and with an estimated bone height of 6 to 8 mm in that area were included. Each patient was randomly allocated to one of the two treatment groups, namely to receive an 11-mm implant (Osseo Speed 4.0 S, Dentsply Implants, Mölndal, Sweden) in combination with maxillary sinus floor elevation surgery or to receive a 6-mm implant (Osseo Speed 4.0 S) without any grafting. After a 3-month osseointegration period, all implants were restored with custom-made titanium abutments and cemented zirconia-based porcelain crowns. Outcome measures were: implant survival; radiographic bone changes; plaque accumulation; bleeding tendency; peri-implant inflammation; presence of dental calculus; biological and technical complications; and patients' satisfaction. Clinical and radiographic examinations were performed at placement of the crown and 12 months thereafter. Patients' satisfaction was scored before treatment and after 12 months of functioning of the crown. RESULTS: One patient of the 11 mm implant group died during the follow-up. No implant failed and no biological or technical complications occurred. From loading to the 12 months follow-up, no difference was found in mean marginal bone changes between the groups (bone resorption in both groups 0.1 ± 0.3 mm). Clinical items revealed very healthy peri-implant soft tissues in both groups. Patients' satisfaction scores were high in both groups. CONCLUSIONS: 6-mm implants and 11-mm implants combined with sinus floor elevation surgery are equally successful to support a single crown in the resorbed posterior maxilla after 1-year follow-up.

AIM: To assess, in a randomized study, the implant (clinical and radiological) and patient outcomes of guided implant placement at 1-year follow-up, compared to conventional implant treatment. MATERIAL AND METHODS: A total of 314 were placed in 59 patients, randomly assigned to one of the treatment groups. Radiographic and clinical parameters were recorded at the time of implant placement, prosthesis instalment (baseline) and at 1-year follow-up. Patient satisfaction was measured with the oral health-related quality of life instrument (OHIP-49). RESULTS: No implants were lost. The mean marginal bone loss after the first year of loading was 0.04 mm (SD 0.34) for the guided surgery and 0.01 mm (SD 0.38) for the control groups. In the guided surgery groups, the mean number of surfaces with BOP and plaque at 1-year follow-up was 1.41 (SD 1.25) and 1.10 (SD 1.22), for the control groups this was, respectively, 1.37 (SD 1.25) and 1.77 (SD 1.64). The mean pocket probing depth was 2.81 mm (SD 1.1) for the guided, and 2.50 mm (SD 0.94) for the control groups. For all treatment groups, a significant improvement in quality of life was observed at 1-year follow-up (p ≤ 0.01), no differences between groups were observed. CONCLUSION: Within the limitations of this study, no difference could be found at 1-year follow-up between the implant and patient outcome variables of guided or conventional implant treatment.

The goal of this quality assurance study was to explore the decision making of clinical faculty members at the University of California, San Francisco School of Dentistry predoctoral dental clinic in terms of caries risk level assignment using the caries risk assessment (CRA) as part of the Caries Management by Risk Assessment (CAMBRA) concept. This research was done in part to determine if additional training and calibration were needed for these faculty members. The study tested the reliability and reproducibility of the caries risk levels assigned by different clinical teachers who completed CRA forms for simulated patients. In the first step, five clinical teachers assigned caries risk levels for thirteen simulated patients. Six months later, the same five plus an additional nine faculty members assigned caries risk levels to the same thirteen simulated and nine additional cases. While the intra-examiner reliability with weighted kappa strength of agreement was very high, the inter-examiner agreements with a gold standard were on average only moderate. In total, 20 percent of the presented high caries risk cases were underestimated at caries levels too low, even when obvious caries disease indicators were present. This study suggests that more consistent training and calibration of clinical faculty members as well as students are needed.

BACKGROUND: Von Willebrand disease (VWD) is the most common inherent bleeding disorder resulting in prolonged bleeding time. Gingival bleeding is a frequently reported symptom of VWD. However, gingival bleeding is also known as a leading symptom of plaque-induced gingivitis and untreated periodontal disease. Gingival bleeding in VWD patients (VWD) may be triggered by gingival inflammation and not a genuine symptom. Thus, this study evaluated whether type 1 VWD determines an increased susceptibility to gingival bleeding in response to the oral biofilm. METHODS: Fifty cases and 40 controls were examined haematologically (VWF antigen, VWF Ristocetin cofactor, factor VIII activity) and periodontally [Gingival Bleeding Index (GBI), bleeding on probing (BOP), Plaque Control Record (PCR), periodontal inflamed surface area (PISA), vertical probing attachment level]. RESULTS: GBI was significantly higher in controls (12.2%) than in VWD (10%). The study failed to find a significant difference regarding BOP between VWD (17%) and controls (17.2%). Multiple regressions identified PCR and PISA to be associated with GBI and BOP. VWD was negatively associated with GBI. Smoking and number of remaining teeth was negatively associated with BOP. CONCLUSION: VWD is not associated with a more pronounced inflammatory response to the oral biofilm in terms of GBI and BOP.

OBJECTIVE: To assess the impact of hospitalization on the oral health status of individuals hospitalized for a short period of time. MATERIAL AND METHODS: This was an observational study of hospitalized patients. The plaque index (PI), gingival index (GI) was measured at baseline (T0 - first 24 h of hospital admission), and at 3 (T1), 7 (T2), 14 (T3) days. RESULTS: One hundred and sixty-two patients were examined at baseline (T0), 35 examined at 3 days (T1), 23 at 7 days (T2) and 16 at 14 days (T3). The main reason for loss of patients was hospital discharge. The mean PI increased at T1 (0.97-1.21; p < 0.001), at T2 (1.06-1.30; p < 0.007) and at T3 (1.19-1.44; p < 0.03). Gingival index (GI) increased at T2 (0.74-0.96; p < 0.04) and at T3 (0.74-0.96; p < 0.02). CONCLUSION: Oral health, assessed through PI and GI, deteriorates after a short period of hospitalization.

BACKGROUND: Osteocalcin, a protein secreted by osteoblasts during bone formation, is negatively associated with adult periodontal disease. Little is known about this association in children. AIM: To examine the extent to which plasma undercarboxylated osteocalcin (ucOC) is associated with gingival crevicular fluid tumour necrosis factor-alpha (GCF TNF-α) - a potential marker of gingival inflammation - in children. METHODS: We used data from the Quebec Adipose and Lifestyle InvesTigation in Youth cohort, an ongoing longitudinal study on the natural history of obesity among Caucasian children with a family history of obesity in Quebec, Canada. This cross-sectional analysis from the baseline visit includes 120 children aged 8-10 years. Plasma ucOC and GCF TNF-α levels were determined by enzyme-linked immunosorbent assay. Linear regression analyses, adjusting for age, gender, family income, sexual maturity stage, daily physical activity, obesity, and fasting glucose were conducted, with TNF-α level as the dependent variable. RESULTS: A 1-ng/ml increase in ucOC was associated with a 0.96% decrease (95% confidence interval (CI): -1.69, -0.23) in GCF TNF-α level. CONCLUSION: A negative association between a marker of bone formation and a marker of gingival inflammation was observed as early as childhood among Caucasian children with a family history of obesity.

The present study reports on a 3-year clinical and radiologic follow-up investigation of dental implants placed 3 and 6 months after sinus augmentation in 14 patients. Augmentation was performed with a synthetic bone substitute material composed of nanocrystalline hydroxyapatite. The aim of the study was to determine how the integration period of the bone substitute material, that is, 3 months or 6 months, influences implant integration within the patient's upper jaw. Therefore, the following clinical and radiologic parameters were investigated: implant being in situ; Periotest value; and presence of peri-implant osteolysis, bleeding on probing, plaque, and soft tissue recession around the implants. At the follow-up investigation 3 years after placement, 23 of 24 implants were in situ and suitable for prosthetic rehabilitation. No implants in either study group were mobile or showed peri-implant osteolysis. Only a few implants showed plaque or soft tissue variations. Within its limits, the present study showed comparable clinical performance of dental implants placed 3 months after sinus floor augmentation to implants placed 6 months after augmentation. The results of all investigated parameters were in accordance with results found in the literature. It can be concluded that augmentation with the applied synthetic bone substitute material already forms a sufficient implantation bed 3 months after augmentation, which enables long-term, stable, implant-retained restoration. These findings might contribute to a reduced healing time after augmentation, which would be favorable for patients and clinicians.

OBJECTIVE: Stress has an adverse effect on oral health and is a risk factor for plaque-associated diseases. The present study aims to assess the effect of academic stress on plaque and gingival health among dental students of Moradabad, India. METHODS: Fifty eligible dental students (age 18 - 22 years) undergoing university examinations participated in the study. Students were examined for plaque index (PII) and gingival index (GI) scores during and after their examinations. Stress levels (using the DASS 21 questionnaire) and oral hygiene behavior were also assessed during and after university examinations and the data were subjected to statistical analysis. RESULTS: The average PII and GI were 1.213 and 0.944, respectively, during examinations and 0.845 and 0.467, respectively, after examinations. The average stress scores were 15.66 and 9.94 during and after examinations, respectively. Eighty-eight percent of the students brushed once and 12% of the students brushed twice during the university examinations, whereas 76% brushed once and 24% of the students brushed twice after their examinations. Thirty-four percent of the subjects rated their thoroughness of brushing as good during university examinations whereas the percentage increased to 80% after the examinations. All the differences were found to be statistically significant. CONCLUSION: Students appearing for the university examinations showed increased stress levels. Moreover, under conditions of stress, the students generally neglected their oral health care and adverse effects on their plaque and gingival scores were observed. Thus, it might be concluded that academic stress has an adverse effect on plaque levels and gingival status in students.

PURPOSE: To evaluate telescopic crown (TC), bar, and locator attachments used in removable four implant-supported overdentures for patients with edentulous maxillae. MATERIALS AND METHODS: A total of 30 maxillary edentulous patients were enrolled in a 3-year prospective study. Ten patients (group A) were treated with overdentures supported by TCs, 10 patients (group B) with overdentures supported by bar attachments, and 10 patients (group C) with overdentures supported by locator attachments. A total of 120 implants were used to restore oral function. During the 3-year follow-up period, implant survival and success rates, biologic and mechanical complications, prosthodontic maintenance efforts, and patient satisfaction were evaluated. RESULTS: All 30 patients were available for the 3-year follow-up and exhibited 100% implant survival and success rates. Peri-implant marginal bone resorption was not statistically significant for the three groups. There were lower plaque, bleeding, gingiva, and calculus indices in group C compared with groups A and B. The number of prosthodontic maintenance visits revealed eight complications in the TC group, seven complications in the bar group, and four complications in the locator group. However, there were no differences in the clinical effects of the overdentures in the three groups. CONCLUSION: Within the limits of this prospective study, it was concluded that the locator system produced superior clinical results compared with the TC and bar attachments in terms of peri-implant hygiene parameters, the frequency of prosthodontic maintenance measures, cost, and ease of denture preparation. However, longer-term prospective studies are required to confirm these results.

INTRODUCTION: The aim of this prospective clinical trial was to examine the predictability of the protocol for premolar transplantation when applied by an inexperienced surgeon. Additional objectives were to examine the hard and soft tissues and to compare the findings with control premolars and also to record the patients' opinions of the treatment provided. METHODS: The sample comprised 23 consecutively transplanted developing premolars in 19 patients. Their mean age at surgery was 12 years 8 months (range, 9 years 10 months-17 years). The mean observation time was 35 months (range, 6-78 months). Plaque accumulation, pocket depth, gingival recession, mobility, and pulp sensitivity were recorded for the transplanted and the control teeth. Standardized radiographs were used to examine hard tissues and crown-to-root ratios. Questionnaires were used to register each patient's opinion about the treatment and its outcome. RESULTS: The survival rate was 100%, and the success rate was 91.3%. No significant differences were recorded between transplanted and control teeth. The patients' perceptions of the surgical management and the treatment outcome were favorable. CONCLUSIONS: The protocol for autotransplantation of developing premolars in growing patients was successfully adopted, regardless of lack of previous experience with this type of treatment.

Even before dementia becomes apparent, cognitive decline may contribute to deterioration in oral health. This cohort study of middle-aged adults evaluated associations of six-year change in cognitive function with oral health behaviors and conditions in the Atherosclerosis Risk in Communities (ARIC) study. Cognitive function was measured at study visits in 1990-1992 and 1996-1998 with three tests: (a) Delayed Word Recall (DWR), (b) Digit Symbol Substitution (DSS), and (c) Word Fluency (WF). Cognitive decline scores were computed as 'studentized' residuals of 1996-1998 scores regressed against 1990-1992 scores. In 1996-1998, 10,050 participants answered dental screening questions, and 5,878 of 8,782 dentate participants received a comprehensive oral examination. Multiple regression models used cognitive change to predict oral health behaviors and conditions with adjustment for covariates. In the fully adjusted models, greater decline in all three measures of cognitive function was associated with increased odds of complete tooth loss. Greater decline in DSS and WF scores was associated with infrequent toothbrushing. Decline in WF scores was also associated with higher plaque levels. In these middle-aged adults, six-year cognitive decline was modestly associated with less frequent toothbrushing, plaque deposit, and greater odds of edentulism, but not with other oral behaviors or diseases.

In the mid-nineties, 27 patients received 31 implant-supported crowns in the anterior maxillary region, and 12 to 15 years later, 18 patients (67%) with 22 implants (67%) participated in a retrospective study evaluating implant survival, bone loss, prosthetic complications, patient satisfaction, and patient and professional evaluation of esthetics. One implant was lost because of implant fracture after 10 years. Mean marginal bone loss was 1.53 mm (standard error ± 0.17 mm). In 6 patients, 6 crowns were replaced and 1 repaired. In 3 patients, 3 crowns had minor unrepaired porcelain fractures. Implant survival was 95.5%, and, despite the high frequency of prosthetic complications, patients were generally very satisfied with the long-term treatment outcome.
