Short-term data suggests cognitive benefits in the elderly with single-implant overdentures.

DESIGN: This study was an extension of a randomized crossover clinical trial approved by the institutional ethics committee (approval number: D2014-148) and adhered to the CONSORT guidelines. The original study juxtaposed patient contentment with single-implant overdentures (1-IODs) against conventional complete dentures (CCDs), with patient satisfaction being the primary focus. In this follow-up study, the cognitive function of edentulous patients receiving 1-IODs was assessed, specifically monitoring for the emergence of mild cognitive impairment (MCI) throughout a three-year period. Patient outcomes were systematically recorded at predetermined intervals: initially, two months post-1-IOD placement, after one year (with groups alternated between denture types at eight-month marks), then after two and three years. A prosthodontist with a decade of expertise performed all denture-related procedures. This follow-up emphasized the cognitive outcomes using the Montreal Cognitive Assessment (MoCA-J), considering it alongside previously documented results on masticatory function, bone resorption, survival rates, and patient-reported outcomes. CASE SELECTION: Between 2015 and 2016, a follow-up study enrolled edentulous patients over 50 years of age who were proficient in Japanese, had sufficient mandibular bone for implants, and were free of systemic health issues and habits that could impact oral health. The participants were randomly divided into two groups after receiving a central mandibular implant. Group 1 initially used 1-IODs, and Group 2 used unloaded CCDs. After two months and subsequent periods, they swapped denture types. Eventually, all patients chose 1-IODs for continued use. Implant success was monitored over three years. The design featured block randomization and accounted for a sample size of 22, determined to be sufficient for evaluating the primary outcome of patient satisfaction. All patients underwent careful allocation and received customized dental interventions, with detailed radiographic planning and surgical precision guiding the implantation process. DATA ANALYSIS: Multivariable linear mixed models were used to assess within-group changes in both overall and specific cognitive function scores across five timepoints. Age, assessment interval, and upper jaw denture status were incorporated as consistent variables, while individual participants were considered variable elements in the analysis. SPSS software version 22.0 was utilized to conduct the statistical tests, and a p value threshold of 0.05 was predetermined to establish statistical significance. RESULTS: Twenty-two patients with edentulous mandibles received 1-IODs. Memory and executive functions saw significant score increases at multiple timepoints over the three-year period, with statistical significance. Though one participant dropped out and another passed away, and two did not complete the 3-year follow-up, the remaining 18 participants provided comprehensive data. Age and type of maxillary denture were significant factors, influencing MoCA-J scores with older participants and those with fixed dentures showing lower scores in certain domains. Overall, the findings illustrated the positive correlation between 1-IODs and cognitive function in older adults. CONCLUSIONS: Older adults with no natural teeth left in their mandible showed improved cognitive function after one and three years of using 1-IODs, as reflected by their total and specific cognitive domain scores. The study suggests that such implant therapy may offer protective benefits against cognitive decline, demonstrating clinical relevance for patient care, regardless of the maxillary arch (antagonist) condition.

Oral health status and dental needs of autistic children and young adults.

AIM: Children with autism might need more dental care than non-autistic, healthy children. The aims of this study were: (a) to describe the caries experience and treatment needs of autistic children aged 6-16 years in the United Arab Emirates; and (b) to provide baseline data at national and regional levels to enable comparisons and future planning of dental services for children with autism. METHODS: All children attending a day centre in Sharjah, United Arab Emirates, for autism were selected for the study. Sixty-one autistic children aged 6-16 years (45 males and 16 females) were included in the study. Each patient received a complete oral and periodontal examination using codes and criteria as described by the World Health Organization. RESULTS: The overall mean for Decayed, Missing, and Filled Teeth/decayed, missing, and filled teeth was 2.4. Female autistic children had significantly higher mean Decayed, Missing, and Filled Teeth/decayed, missing, and filled teeth scores (4.4) than males (1.63). The percentage of decayed, missing, and filled teeth increased with increasing age. The restorative index and met need index for the autistic children aged 11-15 years were 0.02 and 0.10, respectively. CONCLUSION: Effective oral health promotion strategies need to be implemented to improve the oral health status of autistic children.

Do preoperative cutaneous bleeding time tests predict the outcome of intraoral surgical bleeding?

PURPOSE: To determine whether cutaneous bleeding time (BT) is related to perioperative bleeding outcome measures after tooth extraction. To determine whether this investigation is reliable to predict bleeding outcome after an intraoral surgical procedure. METHODS: A prospective clinical pilot study of 30 subjects. Cutaneous BT was evaluated before tooth extraction. After extraction, an oral BT was determined. Subjects were contacted 2-5 hours after extraction to assess further post operative bleeding. RESULTS: The mean cutaneous BT was 2.3 minutes (range 1.5-3.5). The mean oral BT was 9.1 (range 7-12). Cutaneous BT did not correlate with oral BT or any other measures of prospective bleeding. However, the time necessary for extraction correlated with extraction site bleeding 2-5 hours after surgery. CONCLUSION: There was no relationship between cutaneous and oral post extraction BT. The use of BT test as a screening procedure is unnecessary for prediction of prolonged bleeding after tooth extraction or minor surgical procedures in the present situation.

The pattern of maxillofacial fractures in Sharjah, United Arab Emirates: a review of 230 cases.

OBJECTIVE: Maxillofacial injuries constitute a substantial proportion of cases of trauma. This descriptive analytical study assesses the cause, type, incidence, demographic, and treatment data of maxillofacial fractures managed at Al Qassimi Hospital in Sharjah, United Arab Emirates, during a 4-year period and compares them with the existing body of literature on the subject. STUDY DESIGN: The medical records and radiographs of 230 patients treated for maxillofacial fractures at the Al Qassimi General Hospital over a 4-year period (from 1999 to 2002) were reviewed. A number of parameters, including the patient's age, gender, race, occupation, and mechanism of injury, type of facial injuries, treatment modality, and postoperative complications were recorded and assessed. RESULTS: Men 20 to 29 years of age sustained the most maxillofacial fractures. The ratio of males to females was 11:1. Most fractures were caused by motor vehicle crashes (75%), followed by falls (12%) and violent assaults (8%). There were 150 (51%) mandibular, 102 (34%) maxillary, and 22 (7.4%) zygomatic fractures. Regarding distribution of mandibular fractures, the majority (25%, 38/150) occurred in the condyle, 23% (35/150) in the angle, and 20% (30/150) in the body. The distribution of maxillary fractures were 49.0% (50/102) dentoalveolar, 29.4% (30/102) Le Fort I, and 10.7% (11/102) were Le Fort II fractures. More than half of all cases were treated by closed reduction (67%). Complications occurred in 5.6% of patients. CONCLUSION: The findings of this study, compared with similar studies reported in the literature, support the view that the causes and incidence of maxillofacial injuries vary from one country to another and, as such, can provide a guide to the design of programs geared toward prevention and treatment.
