Teeth and alveolar bones as tracers of metals and radionuclides in inhabitants of a uranium region. ENVIRONMENTAL RESEARCH 2024; 259:119510. [PMID: 38971359 DOI: 10.1016/j.envres.2024.119510] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/02/2024] [Revised: 06/06/2024] [Accepted: 06/28/2024] [Indexed: 07/08/2024]
Abstract
Biodosimetry can define risks in inhabitants of areas with potential contaminants, ensuring environmental protection and living conditions due to toxic and radioactive effects. This study aimed to evaluate metals and radionuclides in dental structures and alveolar bones in residents of a uranium area in Paraíba and Pernambuco, Brazil. Eighty-nine specimens were pulverized, fractionated, and chemically prepared for analysis by EDXRF, FAAS, and ICP-MS. Levels of Ca, Cu, Fe, Si, Mn, Ni, Pb, Sr, Ti, V, Zn, K, Mn, Th, and U were investigated. Higher concentrations were measured for Ca, with an average of 272,986.4 mg kg-1. Ni presented in lower concentrations, with an average of 30.4 mg kg-1. For U, concentrations ranged from 1.5 to 145.0 mg kg-1, with more than 27% of the samples above the reference value of 8.1 μg kg-1. For Th, almost 38% of the results were above the limit of 3.5 μg kg-1. In the bone spicules, the contents of U and Th ranged from 45.1 to 1451.2 μg kg-1 and from 7.5 to 78.4 μg kg-1, in this order. The levels of radionuclides were more expressive for the teeth collected in São José do Sabugi, suggesting contamination through food and water consumption. In the bone spicules, the levels of U were up to 179 times higher than the safety limit. The results indicate a possible risk of contamination with probable induced radiobiological effects.

[PMID: 38832953 DOI: 10.1007/s00276-024-03394-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Accepted: 05/21/2024] [Indexed: 06/06/2024]
Abstract
PURPOSE To assess the presence of mandibular canal bifurcation (BMC) and classify these variations by correlating findings with sex, age and facial skeletal pattern, measurements were made, including height, width, and distance from bifurcation to anatomical cortical bones. METHODS BMC was identified in cone beam CT exams of 301 patients and classified according to its origin, location, direction, configuration and ending. The height and width of the MC before and after the bifurcation; height and width of the BMC; and distance from BMC to alveolar (C1), buccal (C2), lingual (C3) and basal (C4) bone cortices were measured. All data were correlated with sex, age, and facial skeletal pattern (class I, II, III). The significance level was 5%. RESULTS 67 BMC (22.26%) were identified in 55 patients (18.28%). Bifurcations were more prevalent in females (p = 0.57), aged 18-39 years (p = 0.40), class I (p = 0.77). Single bifurcations, located in the posterior region of the mandible, originating in the MC, with a superior direction and ending in the retromolar foramen were more prevalent (p > 0.05). Mean cortical measurements were higher in male individuals, with significant differences only at C1 (p = 0.03). The mean height and width of BMC were 2.24 (± 0.62) and 1.75 (± 0.45) mm. There was no association between BMC classification and the variables studied (p > 0.05). CONCLUSION Approximately 1/5 of the population studied had BMC. There were no associations of BMC presence or characteristics with sex, age, and facial skeletal pattern. The distance from bifurcation to alveolar (superior) cortical bone is greater in male individuals.

Abstract
OBJECTIVES To identify the ocuurrence, distribution, and factors associated with lost molars and furcation defects in a sample of the Bulgarian population. MATERIAL AND METHODS The full mouth cone-beam computed tomography of 56 male and 57 female patients, aged between 19 and 84 years, were examined. A comprehensive evaluation was performed on a total of 675 molars-339 in maxilla and 336 in mandible. Associations with variables such as age, gender, and periodontal disease were analyzed. RESULTS With aging the number of missing teeth and interradicular lesions increased. No significant links between gender and molar loss (p = .64) or gender and furcation involvement (p = .25) was found. Periodontitis was strongly associated with both studied dental problems (p < .001). The occurrence of furcation defects was more frequently observed in the maxilla than in the mandible. CONCLUSION The occurrence and distribution of lost molars and furcation defects is substantial within the studied sample. Further investigation with a larger patient cohort is needed. Pertinent healthcare strategies to address the observed dental health issues also have to be developed.

Abstract
BACKGROUND AND OBJECTIVE A treatment approach that is widely used as a permanent and natural replacement for missing or extracted teeth is dental implants .VR is a computer-generated simulation that creates a three-dimensional (3D) image or environment. Advances in VR -based learning allow learners and students to practice and also help professionals plan a wide variety of surgical procedures, including the correct placement of dental implants. Therefore, in this systematic review, our aim was to investigate and evaluate the available virtual reality tools for dental implants and their effectiveness. MATERIALS AND METHODS Studies published up to 01/30/2023 which report the applications of using virtual reality technology in dental implants, were reviewed in three databases, including PubMed, Web of Science, and Scopus. All studies with evidence reporting the role of virtual reality technology in the field of dental implants were included in our analyses, written in English and published in peer-reviewed form, are included. Theoretical articles, and letters that did not provide original data, as well as studies that reported incomplete information, were excluded. Two reviewers independently assessed search results, extracted data, and assessed the quality of the included studies, and decisive agreement was reached by discussion and consultation with the third researcher. Narrative synthesis was undertaken to summarize and report the findings. RESULTS Out of 1633 initial search results, nine were included in the present study based on the inclusion criteria. The focus of seven studies was on teaching and learning, and two studies have examined the implant planning procedure. The most commonly used hardware and software were head-mounted display and Unity3D, respectively. In almost all studies, the results showed that the use of virtual reality-based systems improves and enhances the skills of users, including dental students and specialists. CONCLUSIONS Our findings showed that VR is an effective method for teaching and planning the implant process. Although the use of VR technology is limited for various reasons such as cost, it can increase the skills of dental professionals in performing dental implants.

Cureus 2023; 15:e36990. [PMID: 37139027 PMCID: PMC10151158 DOI: 10.7759/cureus.36990] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Accepted: 02/26/2023] [Indexed: 04/04/2023] Open
Abstract
Background Total treatment time in implant placement can be significantly reduced by placing immediate implants into the freshly extracted sockets. Also, immediate implant placement can act as a guide for proper and accurate implant placement. Additionally, in immediate implant placement, the resorption of bone associated with the healing of the extraction socket is also reduced. This clinical study aimed to clinically and radiographically assess the healing of endosseous implants having different surface characteristics in nongrafted and grafted bone. Methodology In 68 subjects, 198 implants were placed, including 102 oxidized (TiUnite, Göteborg, Sweden) and 96 turned surface implants (Nobel Biocare Mark III, Göteborg) were placed. Survival was considered with clinical stability and acceptable function with no discomfort and no radiographic or clinical signs of pathology/infection. Rest cases that showed no healing and implant no osseointegration were considered failures. Clinical and radiographic examination was done by two experts after two years of loading based on bleeding on probing (BOP) mesially and distally, radiographic marginal bone levels, and probing depth (mesial and distal). Results Five implants failed in total where four implants were with the turned surface (Nobel Biocare Mark III) and one was from the oxidized surface (TiUnite). The one oxidized implant was in a 62-year-old female and was placed in the region of mandibular premolar (44) of length 13 mm and was lost within five months of placement before functional loading. Mean probing depth had a nonsignificant difference between oxidized and turned surfaces with the mean values of 1.6 ± 1.2 and 1.5 ± 1.0 mm, respectively, with P = 0.5984; mean BOP in oxidized and turned surfaces was 0.3 ± 0.7 and 0.4 ± 0.6, respectively (P = 0.3727). Marginal bone levels, respectively, were 2.0 ± 0.8 and 1.8 ± 0.7 mm (P = 0.1231). In marginal bone levels related to implant loading, a nonsignificant difference was seen in early loading and one-stage loading with P-values of 0.06 and 0.09, respectively. However, in two-stage placement, significantly higher values were seen for oxidized surfaces (2.4 ± 0.8 mm) compared to turned surfaces (1.9 ± 0.8 mm), with P = 0.0004. Conclusions This study concludes that nonsignificantly higher survival rates are associated with oxidized surfaces compared to turned surfaces after two years of follow-up. Higher marginal bone levels were seen in oxidized surfaces for single implants and implants placed in two stages.

Prevalence of periodontitis in dentate people between 2011 and 2020: A systematic review and meta-analysis of epidemiological studies. J Clin Periodontol 2023; 50:604-626. [PMID: 36631982 DOI: 10.1111/jcpe.13769] [Citation(s) in RCA: 47] [Impact Index Per Article: 47.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 12/29/2022] [Accepted: 01/03/2023] [Indexed: 01/13/2023]
Abstract
AIM The aim of the study was to evaluate the prevalence of periodontitis in dentate people between 2011 and 2020. MATERIALS AND METHODS PUBMED, Web of Science, and LILACS were searched up to and including December 2021. Epidemiological studies reporting the prevalence of periodontitis conducted between 2011 and 2020 were eligible for inclusion in this review. Studies were grouped according to the case definition of confidence as confident (Centers for Disease Control [CDC] AAP 2012; CDC/AAP 2007; and Armitage 1999) and non-confident (community periodontal index of 3 or 4, periodontal pocket depth >4 mm, and clinical attachment level ≥1 mm). Random effects meta-analyses with double arcsine transformation were conducted. Sensitivity subgroup and meta-regression analyses explored the effect of confounding variables on the overall estimates. RESULTS A total 55 studies were included. The results showed a significant difference, with confident case definitions (61.6%) reporting nearly twice the prevalence as non-confident classifications (38.5%). Estimates using confident periodontal case definitions showed a pooled prevalence of periodontitis of 61.6%, comprising 17 different countries. Estimates reporting using the CDC/AAP 2012 case definition presented the highest estimate (68.1%) and the CDC/AAP 2007 presented the lowest (48.8%). Age was a relevant confounding variable, as older participants (≥65 years) had the highest pooled estimate (79.3%). CONCLUSION Between 2011 and 2020, periodontitis in dentate adults was estimated to be around 62% and severe periodontitis 23.6%. These results show an unusually high prevalence of periodontitis compared to the previous estimates from 1990 to 2010.

Abstract
Background This study aimed to examine the association between oral health behaviors and tooth retention among Chinese older adults.
Methods Data were used from the 4th Chinese National Oral Health Survey, a nationally representative sample. The sample included 9054 older adults aged 55 to 74. Control variables and oral health behaviors were measured through a questionnaire interview, and the number of remaining teeth and periodontal health were obtained from an oral health examination. A chi-square test was used for univariate analysis. Multivariate Logistic regression was used to explore the association between health behaviors and the number of remaining teeth. Results The average number of remaining teeth in the sample was 24.4 ± 7.7. There was a higher proportion of older adults living in urban areas with 20 or more teeth than those living in rural areas (83.2% vs. 79.4%, P < 0.001); and a higher proportion of individuals with high education levels with 20 or more teeth compared to those with low education levels (P < 0.001). Logistic regression models showed that older adults who used toothpicks `(OR = 3.37, 95% CI 2.94–3.85), dental floss (OR = 1.93, 95% CI 1.05–3.53), toothpaste (OR = 3.89, 95% CI 3.14–4.83); and never smoked (OR = 1.43 95% CI 1.20–1.70) were more likely to retain 20 or more natural teeth; whereas older adults who had a dental visit were less likely to retain 20 or more natural teeth (OR = 0.45, 95% CI 0.39–052). Conclusion Good oral hygiene practices, never smoking, and regular dental visits focusing on prevention are significantly associated with teeth retention. It is critical to promote a healthy lifestyle and improve prevention-oriented oral health care systems.

Abstract
Objective: This study compared the effectiveness of auditory distraction and brief relaxation therapy for reducing anxiety in patients undergoing tooth extraction. Methods: A non-blind, three-armed, randomized control trial was carried out. The targeted study population were patients who needed extraction of a non-restorable and non-mobile molar tooth. Eighty-six patients were recruited; the brief relaxation therapy and auditory distraction groups had 32 participants each, while 10 of the 22 participants in the control group were excluded due to missing data. The Hierarchical Anxiety Questionnaire was used to assess the anxiety level. The Mann–Whitney U or Kruskal–Wallis test was performed to compare means between the groups. The before and after comparisons in each group were carried out using the Wilcoxon Signed-Rank test. The alpha value was set at 0.05, and data were analyzed using SPSS version 24. Results: The mean anxiety score after brief relaxation therapy and auditory distraction had significantly decreased (p < 0.001). Although not significant (p = 0.13), there was a slight increase in the anxiety score of the study participants in the control group just before the extraction procedure. Brief relaxation therapy was significantly effective in reducing anxiety scores in comparison to the control group (MD = 5.87, 95% CI = 2.58, 9.17; p = 0.001), but auditory distraction was not (p = 0.14). Conclusion: Both auditory distraction and brief relaxation therapy were effective in reducing patient anxiety before a dental procedure. Furthermore, it would be interesting to learn if these findings remain consistent for more complex dental procedures, such as surgical removal of an impacted third molar.

Abstract
The problems of anterior teeth include dental plaque, dental caries, and fracture, which are usually treated with common composite resin clinically. Although good repair effect can be achieved, patients are prone to anterior tooth sensitivity after surgery. Therefore, the purpose of this study is to analyze the cosmetic effect of nanocomposite resin on anterior teeth. Up to 176 patients (176 teeth) undergoing anterior dental cosmetic restoration in our hospital were selected and assigned to the LR group (n = 88) and the NR group (n = 88) according to patients' voluntary choice of prosthetic materials. The LR group was cured with light-cured composite resin, while the NR group was cured with nanocomposite resin. By comparing the related indexes of patients in the two groups, it was discovered that in the NR group, the excellent and good rate and patients' evaluation of the repair effect were higher, while the periodontal attachment, gingival index, dental plaque index, VAS score, and the incidence of tooth sensitivity were lower, all P < 0.05. The results indicated that the nanocomposite resin had significant cosmetic effect on anterior teeth and had application value.

Abstract
OBJECTIVE The aim of this study was to describe the prevalence of depressive symptoms and determine the association with oral health variables in older adults belonging to an oral health cohort. METHOD A prospective longitudinal study was conducted between 2009 and 2015. A standardized questionnaire was administered to collect demographic-socioeconomic variables and self-perceived oral health status. The clinical oral examinations were performed by examiners who had undergone training and calibration exercises. Depressive symptoms (outcome) were measured using the Geriatric Depression Scale (GDS-15), with a score of five points or higher considered indicative of the presence of depressive symptoms. RESULTS A total of 439 and 163 older adults (≥60 years of age) were evaluated in 2009 and 2015, respectively. The prevalence of depressive symptoms was 18.3% in 2009 and 28.5% in 2015. In the adjusted Poisson regression model, older adults who experienced tooth loss between 2009 and 2015 (PR = 1.86; 95% CI: 1.01-3.53) and those with a sensation of dry mouth in 2015 but not in 2009 (PR = 3.25 95% CI: 1.56-6.72) were at greater risk of exhibiting depressive symptoms. CONCLUSION In this study, the prevalence of depressive symptoms was considerable. Older adults with tooth loss between 2009 and 2015 and those with a perception of dry mouth were at greater risk of exhibiting depressive symptoms, which underscores the importance of including a dentist as part of the health team for the prevention and treatment of mental health problems.

[PMID: 34386230 PMCID: PMC8346357 DOI: 10.1016/j.amsu.2021.102639] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Revised: 07/26/2021] [Accepted: 07/26/2021] [Indexed: 11/23/2022] Open
Abstract
Purpose This paper aims to evaluate the decision-making of wisdom teeth extractions (M3s extraction) and the epidemiological profile in the targeted population. Materials and method This was a prospective analysis study of 106 patients at our hospital august 20, 1953 specialist hospital, which is a referral center between January 1, 2020 and January 1, 2021. The patients are divided into 2 groups according decision-making of wisdom teeth removal based on scientific evidence if it's right or wrong. Results There was no statistically significant difference between the groups regarding sex (P = 0.478), educational level (P = 0.718), or working status (P = 0.606). Furthermore, there was no statistically significant difference between the groups regarding general co-morbidity (P = 1.00) or oral history (P = 0.28). The mean age of the sample was 32.12 years (SD = 11.337 years, range = 17–70 years, median = 30 -years). We reported that only 28% of the third molars were surgically extracted. We included in Group (I), 81 patients who were treated for third molars removal which the decision-making was justified. In Group (II), 25 patients were treated for third molars removal which the decision-making was unjustified. Group (I) comprised 30 men and 51 women with a mean age of 30 years. Group (II) comprised 7 men and 18 women with a mean age of 27 years. The assessment of surgical outcomes (operating time, blood loss, hospital stay) showed no difference between groups. Discussion Monitoring asymptomatic wisdom teeth appears to be an appropriate strategy. Regarding retention versus prophylactic extraction of asymptomatic wisdom teeth, decision-making should be based on the best evidence combined with clinical experience.76.4% had a reason for extraction that was justified. The reasons why extraction of the wisdom tooth was not justified in our study population was either: extraction for prophylaxis or in the case of asymptomatic non-pathological third molars; without scientific evidence. Conclusion This subject, which is perpetually debated, requires updating dental health authorities by evaluating new conservative procedures. Third molars are a major focus of interest in dentistry. Preliminary indication and wrong decision-making for teeth extraction have resulted in many healthy teeth being sacrificed. Debate continues about the best strategies for the management of wisdom teeth.

Abstract
OBJECTIVE The objective of this study was to evaluate the association between SLC6A4 (rs1042173 and rs3813034), DRD2 (rs6275 and rs6276), ANKK1 (rs1800497), and COMT (rs174675) genetic polymorphisms and alterations in anxiety levels and vital signs in individuals undergoing third molar extractions. STUDY DESIGN One hundred sixty-eight individuals were evaluated at the pre-, trans-, and postoperative periods by checking systolic blood pressure, diastolic blood pressure, heart rate, respiratory rate, and body temperature. Anxiety levels were assessed using the State-Trait Anxiety Inventory (STAI). Buccal mucosa cells were collected for genetic evaluation using real-time polymerase chain reaction. Statistical analysis was performed at a significance level of 5%. RESULTS The level of anxiety was associated with rs1800497 for STAI-Trait (P = .031) and rs174675 for STAI-State (P = .007). Considering the vital signs, there was a significant difference between the values of respiratory rate and rs1042173 (P = .029), rs3813034 (P = .024), and rs6275 (P = .025). The diastolic blood pressure values differed significantly for rs1042173 (P = .042), and the body temperature values differed significantly for rs174675 (P = .016). CONCLUSIONS Polymorphisms in SLC6A4, DRD2, ANKK1, and COMT genes could be associated with alterations in anxiety levels and vital signs in individuals undergoing third molar extractions.

Abstract
Purpose This study aimed to explore the reasons for tooth extraction and investigated the potential correlations between tooth loss and several variables including age, gender, education level, and other risk factors, such as diabetes and smoking habit. Patients and Methods The study retrospectively analyzed 1811 dental records of patients who underwent extraction procedure of at least one tooth. Patients’ variables included: age, gender, level of education, diabetes, and smoking habit. Reasons for extraction were recorded as follows: caries, periodontal disease, endodontic treatment complications, orthodontic treatment, impactions, trauma, pre-prosthetic, and others (esthetic reasons, tooth malposition, or unspecified reasons). Statistical analysis The significance of variables was analyzed by Chi square test, P < 0.05. The variances in the mean number of extracted teeth per patient were investigated using ANOVA. Pearson correlation test was used to test the strength of the association among the tested variables, P < 0.01. Results Out of 1811 reviewed patients’ records, 2654 extracted teeth were identified. Males had a higher number of extracted teeth, 1447 (54.5%), than females, 1207 (45.5%). Males had more extractions due to periodontal disease, while females had more extractions for orthodontic and pre-prosthetic reasons. The highest mean of extracted teeth was identified among the 51-year-old and above age groups (3.73 ± 0.53 teeth) where periodontal disease was shown to have a significant association (P < 0.05). Diabetic patients showed a significant association with periodontal diseases, while smokers showed a significant association with caries. Both diabetics and smokers had moderate correlation (0.055 and 0.04, respectively). Conclusion Caries, periodontal disease, and endodontic complications were the most common causes of tooth extraction. In addition, this study indicated that age, diabetes, and smoking habits were found to be suitable forecasters for permanent tooth loss as these variables displayed significant statistical association.

Postendodontic Pain after Pulpotomy or Root Canal Treatment in Mature Teeth with Carious Pulp Exposure: A Multicenter Randomized Controlled Trial. Pain Res Manag 2020; 2020:5853412. [PMID: 32676136 PMCID: PMC7345601 DOI: 10.1155/2020/5853412] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2019] [Revised: 04/13/2020] [Accepted: 05/06/2020] [Indexed: 12/21/2022]
Abstract
This equivalence, randomized, clinical trial aimed to compare the postoperative pain of root canal therapy (RCT) with pulpotomy with mineral trioxide aggregate (PMTA) or calcium-enriched mixture (PCEM) in permanent mature teeth. In seven academic centers, 550 cariously exposed pulps were included and randomly allocated into PMTA (n = 188), PCEM (n = 194), or RCT (n = 168) arms. Preoperative “Pain Intensity” (PI) on Numerical Rating Scale and postoperative PIs until day 7 were recorded. Patients' demographic and pre-/intra-/postoperative factors/conditions were recorded/analysed. The arms were homogeneous in terms of demographics. The mean preoperative PIs were similar (P=0.998), the mean sum PIs recorded during 10 postoperative intervals were comparable (P=0.939), and the trend/changes in pain relief were parallel (P=0.821) in all study arms. The incidences of preoperative moderate-severe pain in RCT, PMTA, and PCEM arms were 56.5%, 55.7%, and 56.7%, which after 24 hours considerably decreased to 13.1%, 10.6%, and 12.9%, respectively (P=0.578). The time span of endodontic procedures was statistically different; RCT = 69.73, PMTA = 35.37, and PCEM = 33.62 minutes (P < 0.001). Patients with greater preoperative pain, symptomatic apical periodontitis, or presence of PDL widening suffered more pain (P=0.002, 0.035, and 0.023, resp.); however, other pre-/intra-/postoperative factors/conditions were comparable. Pulpotomy with MTA/CEM and RCT demonstrate comparable and effective postoperative pain relief.

Abstract
Objectives:
To evaluate the pattern and reasons for permanent tooth extractions in an adult patient seeking free dental care at clinics of the University of Science and Technology of Fujairah, UAE.
Methods:
The current retrospective study involved patients who had a dental extraction in the student dental clinics of the University of Science and Technology of Fujairah. Data of 1000 randomly selected extractions were collected from the archive of the university dental clinics.
Results:
Males had more teeth extracted (88.3%) than females. The most frequent extraction (58.9%) was in individuals of 30-49 years old range. Dental caries was the major reason (44.6%) of extractions, followed by wisdom teeth related extraction (23.4%), periodontal disease (18.1), failure of endodontically treated teeth (8.7%), prosthetic reasons (2.6), orthodontic reasons (1.7%), and trauma (0.9%) respectively. The most extracted teeth were the maxillary posterior teeth (45.6%), followed by mandibular posterior teeth (38.2%); then, maxillary anterior teeth (8.8) and lastly, were the mandibular anterior teeth (7.4%). Caries was significantly more frequent in female gender (χ2= 250.126; p=.000), while the periodontal disease was more common in male gender (χ2 = 146.790; p=.000).
Conclusion:
Caries is the principal reason for tooth extractions, followed by wisdom teeth related problems and periodontal disease. There is an increasing percentage of tooth extraction due to periodontal disease with both aging and male gender. Caries was the more frequent reason for extraction in all quadrants, except the lower anterior teeth in which periodontal disease was the more frequent reason. Lastly, anterior teeth were retained in the oral cavity more than posterior teeth.

Abstract
The objective of this cross-sectional study was to determine the type of care that can be achieved and the epidemiological profile of patients attending the 3 public dental practices in the Haut-Sassandra region, in Côte d'Ivoire. The data collection concerned socio-demographic characteristics, reason for consultation, oral hygiene, dental condition, malocclusions and the availability of equipment for the performance of procedures. The 400 patients observed (51.5% male) were aged 16.0 to 86.0 years (mean=35.5 years; SD=13.1 years). The main reasons for consultation were pain (91.5%) and aesthetics (23.5%). Oral hygiene was insufficient for 36.8% of subjects. Oral conditions were malocclusions (12.8%), caries (98.7%) and edentulous (65.7%) with only 11.8% with prosthesis. The average DMFT index was 9.3. Only extractions and resin attached prostheses were possible in all 3 health facilities. Preventive dentistry (sealent, fluoridation), dentofacial orthopedics and implantology were not available in any dental practice. The most frequently performed acts were extractions (74.5%). The results of this study highlight the need for oral health planning with service equipment and awareness among populations who shouldn't wait until they are in pain to consult.

Abstract
OBJECTIVE To evaluate the factors associated with tooth loss in adults from the position and number of teeth lost in the dental arches. METHODS This is a cross-sectional, population-based study with adults participating in the epidemiological survey of oral health of São Paulo in 2015. The outcome of the study was tooth loss, assessed by the proposed classification, namely: I) lost up to 12 back teeth; II) lost up to 12 teeth (including front teeth); and III) lost more than 12 teeth. A four-block analysis was conducted, supported by a conceptual theoretical model adapted for tooth loss. For the multinomial logistic regression, "individuals who did not lose teeth due to caries or periodontal disease" was used as reference (p < 0.05). RESULTS Of 6,051 adults evaluated, 25.3% (n = 1,530) were classified in category I, 32.7% (n = 1,977) in II, 9.4% (n = 568) in III, and 1.9% (n = 117) were edentulous. Lower income and schooling, the perception of need for treatment and the last appointment motivated by routine, pain or extraction were associated with tooth loss, regardless of the classification. The negative evaluation of the dental service was associated with individuals who lost up to 12 teeth, both front and back. The presence of women and periodontal pocket were associated with tooth loss of up to 12 teeth, including front, and more than 12 teeth. Caries were associated with adults who lost up to 12 teeth, including front teeth. CONCLUSION The proposed classification allowed the identification of differences between the associated factors. Thus, the need to consider such classification in future studies is evident.

Abstract
Teeth are vital sensory organs that contribute to our daily activities of living. Unfortunately, teeth can be lost for several reasons including trauma, caries, and periodontal disease. Although dental trauma injuries and caries are more frequently encountered in a younger population, tooth loss because of periodontal disease occurs in the older population. In the dental implant era, the trend sometimes seems to be to extract compromised teeth and replace them with dental implants. However, the long-term prognosis of teeth might not be comparable with the prognosis of dental implants. Complications, failures, and diseases such as peri-implantitis are not uncommon, and, despite popular belief, implants are not 99% successful. Other treatment options that aim to save compromised or diseased teeth such as endodontic treatment, periodontal treatment, intentional replantation, and autotransplantation should be considered on an individual basis. These treatments have competing success rates to dental implants but, more importantly, retain the natural tooth in the dentition for a longer period of time. These options are important to discuss in detail during treatment planning with patients in order to clarify any misconceptions about teeth and dental implants. In the event a tooth does have to be extracted, procedures such as decoronation and orthodontic extrusion might be useful to preserve hard and soft tissues for future dental implant placement. Regardless of the treatment modality, it is critical that strict maintenance and follow-up protocols are implemented and that treatment planning is ethically responsible and evidence based.

Abstract
The aim of this study was to identify the risk factors for tooth loss in an extended age group of adults over 4 years. The prospective cohort study assessed adults (20–64 years old) in 2011 and 2015, from Piracicaba, São Paulo, Brazil. The sample selection was planned based on the adult population in the city. The inclusion criteria were randomly selected residences per census tract unit (one adult per household). The exclusion criteria comprised of a physical or psychological state that prevented the achievement of clinical procedures or understanding of the questionnaire. The home oral examination was performed using the index of decayed, missing, and filled teeth (DMFT), the Community Periodontal Index according to the World Health Organization, and visible biofilm. Demographic and socio-economic data, information on health habits, and the use of dental services were obtained by questionnaire. The outcome was a presence incidence of tooth loss, assessed by the difference between Missing teeth (M>0) from DMFT in 2011 and that in 2015. The conceptual theoretical model ‘Ethnicity, aging and oral health outcomes’ was adapted for tooth loss and used in a Hierarchical multivariate Poisson Regression analysis (p<0.20). The reference category for the Poisson regression were individuals who had no missing teeth (M) due to caries or periodontal disease (p<0.05). There were a total of 143 (follow-up rate = 57.7%) participants in the four-year study, and there was incidence of tooth loss in 51 (35.7%) adults over this period. The risk factors for tooth loss were reason for seeking dental services by pain (RR = 2.72; 95.0% CI: 1.04–7.37), previous tooth loss (RR = 3.01; 95.0% CI: 1.18–7.73) and decayed teeth (RR = 2.87; 95.0% CI: 1.22–6.73). The risk factors for tooth loss were: reason for seeking dental services by pain, previous tooth loss and dental caries.

Abstract
BACKGROUND Bicortical screw implants may be used in both healed bone and fresh extraction sockets and loaded immediately. To date, there have not been too many studies reporting clinical results of such screws used in periodontally involved sites. This study aimed to assess many aspects of bicortical screw implants used to retain full-arch and segmental cemented prostheses in the rehabilitation of the mandible and maxilla in patients with or without a history of periodontal disease. MATERIALS AND METHODS This retrospective review involved 87 patients, of whom 77 had a history of periodontitis diagnosed before implant placement and 10 did not. They were treated following the same surgical procedure and received a total of 1019 implants which were immediately loaded with fixed prosthetic works. RESULTS A total of 1019 polished surface, one-piece, bicortical screw implants were used in 87 patients who underwent the same surgical treatment, i.e., tooth extraction and immediate implant placement were investigated, of which 526 were placed in the healed bone and 493 in fresh extraction sockets with the mean follow-up time of 22.2 ± 7.3 months. Results were analyzed using log-rank test, the Kaplan-Meier method, Chi-square test, and t-test. Cumulative survival at 12, 24, and 35 months after placement was 99.3%, 98.6%, and 97.0%, respectively. CONCLUSION Bicortical smooth surface implant concept with immediate loading protocol provided predictable outcomes and survival rate of 99% in patients with and without a history of periodontitis. More studies are needed to further support the clinical advantages of bicortical anchoraged smooth surface implants.

Abstract
Objective To describe the methodological aspects of a Prospective Cohort Study of adult oral health in Piracicaba, Brazil. Results This Prospective Cohort Study evaluated adults (20–64 years old) between the years of 2011 and 2015, in Piracicaba, São Paulo, Brazil. The main objective was to evaluate the risk factors for tooth loss in adults. Data were collected at households and selected via probabilistic sampling, through clinical examination of caries, considering as variables the decayed, missing and filled permanent teeth index, need for caries treatment, periodontal disease (Community Periodontal Index and Periodontal Attachment Loss), use and need for dental prosthesis, and presence of visible biofilm. A questionnaire about demographic, socioeconomic and health habits, use of dental services, self-perceived quality of life (Oral Health Impact Profile-14) and health literacy (14-item Health Literacy Scale) was also employed. In 2011, 248 adults participated, and in 2015, 143 (follow-up rate = 57.7%). Despite the follow-up sample loss, most sociodemographic characteristics remained in the participant sample: for example, women (72.0%) (p = 0.534), family income between R$545,00 and R$1090,00 (63.9%) (p = 0.920), above 11 years of education (53.1%) (p = 0.200) and belonging to middle class (67.1%) (p = 0.909).
