Combined Implant and Tooth Support: An Up-to-Date Comprehensive Overview

Objectives. This article presents a review on the concerned topics and some considerations related to the concept of splinting teeth and implants in the rehabilitation of partial edentulism. Study Selection. An electronic PubMed/MEDLINE and manual search of identified articles and reviews as well as clinical, laboratory, and finite element studies was performed in this project. Due to the shortage in within-subject, long term, randomized, controlled clinical trials regarding the subject a meta-analysis was not possible. Results. Although surrounded with some controversy, joining teeth and implants during the rehabilitation of partial edentulism provides the clinicians with more treatment options where proprioception and bone volume are maintained and distal cantilevers and free end saddles are eliminated. It makes the treatment less complex, of less cost, and more acceptable for the patient. Conclusions. Whenever suitable and justified, combining implant and tooth support might be recommended as an alternative during rehabilitation of partial edentulism. Based on the literature, clinical tips and suggestions were recommended to increase the success of this treatment

Multiple Lingual Cusps Trait on Mandibular Premolars and Hypoconulid Reduction Trait on Mandibular First Molar in Living Jordanian Population. Intra- and Inter-trait Interactions

The objective was to determine the expression and fluctuating asymmetry of two dental morphological traits in the living Jordanians: The lingual cusp number on the lower premolars (LP1 and LP2) and the hypoconulid (distal cusp) reduction on the lower first molar (LM1). In addition, both intra- trait and inter- trait interactions were analyzed. Three hundred school children (15.5± 0.4 years) were involved. Impressions for the mandibular dental arches were taken, and dental casts were reproduced. The above-mentioned traits were observed. Paired sample t test and nonparametric corre- lation analysis were used for data analysis. Three-cusped LP1 was found in 11.40 % of the examined students, while the two-cusped LP1 was found in 88.60%. In comparison, the Three-cusped LP2 was found in 61.40% while the two-cusped LP2 was found in 38.60% of the observed subjects. The frequencies of the 4-cusped and 5-cusped LM1 were found to be 8.65% and 91.35%, respectively. Nonparametric correlation analysis revealed positive and statistically significant asso- ciation between the expression of two lingual cusps on LP1 and on LP2 in both genders (p0.05). Bilateralism was highly significant in the tested traits in both genders (p<0.001).This finding might be a sign of relatively low environmental stresses experienced by the living Jordanians and/or great ability of its individuals to buffer the adverse effects of such stresses on dental development. This study is a useful addition to the ex- isting literature in that it examines a previously poorly characterized population and assists in placing the contemporary Jordanian population within the current framework of human population groups globally

Ozone Treatment of Recurrent Aphthous Stomatitis: A Double Blinded Study

This study aimed to evaluate the use of ozone to treat recurrent aphthous stomatitis (RAS). Consecutive sixty-nine participants with RAS were recruited into this non-randomized double blind, controlled cohort observational study (test group). A control group of 69 RAS patients who matched test group with age and gender was recruited. RAS lesions in test group were exposed to ozone in air for 60 seconds while controls received only air. Ulcer size and pain were recorded for each participant at baseline and daily for 15 days. Ulcer duration was determined by recording the time taken for ulcers to disappear. The main outcome measures were pain due to the ulcer, ulcer size and ulcer duration. 138 RAS participants (69 participants and 69 controls) were analyzed. Ulcer size was reduced starting from the second day in test group and from the fourth day in control. Pain levels were reduced starting from the first day in the test group and from the third day in controls. Ulcer duration, ulcer size after day 2 and pain levels were more reduced in the test group. In conclusion, application of ozone on RAS lesions for 60 seconds reduced pain levels and enhanced ulcers’ healing by reducing ulcers’ size and duration

Relationship between Impacts of Complete Denture Treatment on Daily Living, Satisfaction and Personality Profiles

Objectives: To investigate the association between satisfaction with conventional complete denture prostheses (CDs), impacts of CDs on daily living and personality profiles. Materials and methods: Fifty-six patients (28 males and 28 females; mean age 53.79 ± 7.762 years) with fitted upper and lower removable CDs were recruited for this study. Clinical success of CDs was assessed according to specific clinical criteria. The dental impact on daily living questionnaire (DIDL) was used to measure satisfaction with CDs and their impacts on daily living. NEO five factor inventory (NEO - FFI) was used to measure patients’ personality profiles. Pearson correlation test and regression models were used to analyze the collected data. Results: Females were more satisfied with appearance and less satisfied with eating and scored higher on neuroticism, and lower on extraversion and openness personality domains (p < 0.05). Older patients were more satisfied with appearance and less satisfied with oral comfort and general performance (p < 0.05). Neuroticism, extraversion, openness and agreeableness personality profiles could predict and had significant relationship with CDs impacts on daily living and satisfaction with CDs. Conclusion: Psychological profiles (e.g. neuroticism, extraversion, openness and agreeableness) might play a role and explain CDs impacts on daily living and patients’ satisfaction with their oral status and CD treatment, therefore, might be used to predict satisfactory outcomes of CD treatment. In this regard, technical aspects of CDs are less essential when the prosthesis is clinically successful. Clinical significance: Psychological factors may play a role and also provide valuable information for the prediction of satisfactory outcomes of complete denture treatmen

Narghile (water pipe) smoking among university students in Jordan: prevalence, pattern and beliefs

<p>Abstract</p> <p>Background and objectives</p> <p>Narghile is becoming the favorite form of tobacco use by youth globally. This problem has received more attention in recent years. The aim of this study was to investigate the prevalence and pattern of narghile use among students in three public Jordanian universities; to assess their beliefs about narghile's adverse health consequences; and to evaluate their awareness of oral health and oral hygiene.</p> <p>Methods</p> <p>The study was a cross-sectional survey of university students. A self-administered, anonymous questionnaire was distributed randomly to university students in three public Jordanian universities during December, 2008. The questionnaire was designed to ask specific questions that are related to smoking in general, and to narghile smoking in specific. There were also questions about oral health awareness and oral hygiene practices.</p> <p>Results</p> <p>36.8% of the surveyed sample indicated they were smokers comprising 61.9% of the male students and 10.7% of the female students in the study sample. Cigarettes and narghile were the preferred smoking methods among male students (42%). On the other hand, female students preferred narghile only (53%). Parental smoking status but not their educational level was associated with the students smoking status. Smokers had also significantly poor dental attendance and poor oral hygiene habits.</p> <p>Conclusion</p> <p>This study confirmed the spreading narghile epidemic among young people in Jordan like the neighboring countries of the Eastern Mediterranean region. Alarming signs were the poor oral health awareness among students particularly smokers.</p

Psychological profiles in patients with recurrent aphthous ulcers

The aim of this study was to investigate the psychological profiles of patients with recurrent aphthous ulcers (RAUs). 50 patients (27 men and 23 women, mean age 31.44 ± 9.95 years) with diagnosed RAUs participated in this study. 50 controls who matched the patients in age and gender were also recruited. The participants' personality and psychological profiles were assessed using the Hospital Anxiety and Depression Scale (HAD) and the Neuroticism-Extraversion-Openness Five Factor Inventory (NEO-FFI). Data analysis showed that females had higher HAD anxiety scores than males in both patients and controls. Patients' age, intensity of pain and number, position, duration, and frequency of ulcers had no relation to HAD and NEO-FFI scores. Patients reported higher levels of anxiety in comparison to controls, but both reported comparable depression scores. Patients' NEO-FFI scores were not different from those reported by controls and the psychological profiles of patients and controls were similar. In conclusion; stressful situations and conditions (i.e. anxiety) rather than personality profiles and stable psychological traits were related to the occurrence of recurrent aphthous ulcers. © 2011 International Association of Oral and Maxillofacial Surgeons

Randomized controlled clinical trial on bleaching sensitivity and whitening efficacy of hydrogen peroxide versus combinations of hydrogen peroxide and ozone

Abstract The clinical efficacy regarding bleaching sensitivity and tooth shade lightening using a standard hydrogen peroxide (H2O2) bleaching gel was compared with the additional use of ozone either before or after application of H2O2. Using computer-generated tables, 45 participants were randomly allocated into three groups (n = 15 each) in this investigator-driven, single-centre trial. In Group 1, upper anterior teeth were bleached using ozone (produced via a healOzone X4 device) for 60 seconds, then 38% H2O2 for 20 minutes; in Group 2, 38% H2O2 application (20 min) was followed by ozone (60 s); air produced by the healOzone machine (60 s) followed by 38% H2O2 (20 min) was used in Group 3 (control). Bleaching sensitivity was evaluated via visual analogue scales, and a treatment-blinded reader objectively recorded tooth shades using a colorimeter before and 24 hours after bleaching (at α = 0.05). The H2O2/ozone combination did not result in pain sensations, while both ozone/H2O2 and H2O2 alone increased bleaching sensitivity (p < 0.001). Teeth achieved lighter shades (higher L*/lower b* values) after bleaching in all groups (p < 0.001), while Ozone boosted lighter tooth shades, irrespective of its use before or after H2O2 (p < 0.05). Due to the complimentary effects, applying ozone after H2O2 seems preferable for bleaching

Quantification of incisal tooth wear in upper anterior teeth : conventional vs new method using toolmakers microscope and a three-dimensional measuring technique

Objectives This study aimed to quantify tooth wear in upper anterior teeth using a new CAD-CAM Laser scanning machine, tool maker microscope and conventional tooth wear index. Methods Fifty participants (25 males and 25 females, mean age=25±4 years) were assessed for incisal tooth wear of upper anterior teeth using Smith and Knight clinical tooth wear index (TWI) on two occasions, the study baseline and 1 year later. Stone dies for each tooth were prepared and scanned using the CAD-CAM Laser Cercon System. Scanned images were printed and examined under a toolmaker microscope to quantify tooth wear and then the dies were directly assessed under the microscope to measure tooth wear. The Wilcoxon Signed Ranks Test was used to analyze the data. Results TWI scores for incisal edges were 0–3 and were similar at both occasions. Score 4 was not detected. Wear values measured by directly assessing the dies under the toolmaker microscope (range=113–150μm, mean=130±20μm) were significantly more than those measured from Cercon Digital Machine images (range=52–80μm, mean=68±23μm) and both showed significant differences between the two occasions. Conclusions Wear progression in upper anterior teeth was effectively detected by directly measuring the dies or the images of dies under toolmaker microscope. Measuring the dies of worn dentition directly under tool maker microscope enabled detection of wear progression more accurately than measuring die images obtained with Cercon Digital Machine. Conventional method was the least sensitive for tooth wear quantification and was unable to identify wear progression in most cases

Relationship between personality and impacts of implant treatment on daily living

Purpose: The objective of this study was to investigate the relationship between satisfaction with implant-supported fixed rehabilitations (ISFPR), their impacts on daily living, and personality profiles. Materials and Methods: Fifty patients (15 men and 35 women; mean age 44.3±9 years), with fitted ISFPR, and 50 partially dentate controls matched with age and gender participated in this study. A Dental Impact on Daily Living questionnaire was used to assess dental satisfaction and impacts of ISFPR on daily living. NEO Five Factor inventory was used to assess participants' personality profiles. Pearson correlation, analysis of variance, and linear regression tests were used for statistical analysis of the data. Results: Patients with ISFPR were more satisfied with their dentition than controls (p<.05). Patients and controls demonstrated different relationships between personality, impacts on daily living, and satisfaction. Neuroticism, extraversion, and conscientiousness had significant relationships with satisfaction and impacts on daily living in both groups (p<.05). Openness and agreeableness had significant relationships with satisfaction and impacts on daily living in patients' group (p<.05). Conclusion: ISFPR had positive impacts on participants' daily living and dental satisfaction. Personality traits (neuroticism, extraversion, openness, agreeableness, and consciousness) impact on daily living and satisfaction with ISFPR, and might predict satisfaction with ISFPR and their impacts on daily living
