The Pattern of Tooth Loss for Periodontally Favorable Teeth: A Retrospective Study.

To retrospectively analyze local and systemic factors that resulted in the short-term tooth loss of teeth that were previously assigned a favorable prognosis in patients who were seen and treated over an observational five-year period. This retrospective study included the records of patients who had a minimum of two dental exams at least twelve months apart over a 5-year period. This study investigated extracted teeth with an initially favorable periodontal prognosis that were then divided into one of four categories based on the reason for extraction: caries, periodontal disease, endodontic reasons, or fracture. Patient- and tooth-related factors associated with the extracted teeth were recorded: crown-to-root ratio, initial pocket depth, initial periodontal diagnosis, maintenance interval, presence of existing restoration, furcation involvement, and systemic conditions. Data analysis was performed using a linear mixed model. A total of 50 patients with 111 teeth met the inclusion criteria for this study. A higher odds ratio (OR) for tooth loss due to caries, endodontic reasons, and fracture were found in teeth with a history of root canal treatment with an OR of 3.61, 3.86, and 2.52, respectively. For tooth loss due to periodontal disease, higher ORs were found in patients who were on anti-depressants (OR = 4.28) and patients who had an initial diagnosis of Stage III/IV periodontitis (OR = 2.66). In addition, teeth with initial probing depths ≥5 mm (OR = 4.32) and with furcation involvement (OR = 1.93) showed a higher OR for tooth loss due to periodontal disease. Within the limitations of this study, previously root-canal-treated teeth present a higher OR for early loss due to caries, recurrent endodontic lesions, or fracture. In addition, patients with anti-depressant medication use, sporadic maintenance, initial probing depths ≥5 mm, and furcation involvement represent a significantly higher OR of tooth loss due to periodontal disease even for initially favorable teeth.

Residual dentition, prosthesis type and oral health-related quality of life in Uruguayan adults.

To investigate the association between different types of dental prostheses (and residual dentition) and oral health-related quality of life (OHRQoL). A population-based study with a representative sample of adults and older adults in Uruguay (2010-2011). The dependent variable was the score on the oral impact on daily performance (OIDP), and the main predictor was the pattern of tooth loss and prosthesis use. Covariates included sex, age, socioeconomic status, education, missing teeth, pain and decayed teeth. Negative binomial regression was used. The sample comprised 762 participants. Those participants not wearing a prosthesis and with extensive tooth loss had a mean OIDP of 3.1 (95% CI=1.6-6.2), while those wearing removable partial dentures (RPD) and having <12 missing teeth had a mean OIDP of 3.6 (95% CI=1.3-10.0). Participants with a free-end saddle had the highest mean OIDP, at 4.9 (95% CI=2.0-12.1). For participants with ≤12 missing teeth, any additional missing tooth was associated with an 11% higher OIDP score. Participants who wore RDPs reported fewer impacts on OHRQoL if they had extensive tooth loss or anterior tooth loss than those with a free-end saddle, or who had lost fewer teeth. The use of RPDs is associated with better OHRQoL. These findings may be valuable in clinical practice and prosthetic planning.

Type of partial edentulousness among patients visiting the department of prosthodontics in a dental college

Background: There are various combinations of partial edentulism pattern in mandible and maxilla. Documenting the pattern of tooth loss is important for health care planning as it indicates the health of people and satisfaction of oral health care system. Objectives: To find out different types of partial edentulism among patients who come to the Department of Prosthodontics for prosthesis. Methods: A descriptive cross sectional study was carried out in 350 patients at Kathmandu Medical College and Teaching Hospital (KMCTH) visiting Department of Prosthodontics over the period of three months (July 2021 - September 2021) by convenience sampling method with complaint of partial edentulism. Ethical approval for the study was granted by Institutional Review Committee of KMCTH on 8th June 2021. The data obtained were entered and analysed using Statistical Package for Social Sciences (SPSS) v.18. Results: Single most common reason for tooth loss was found to be dental caries (102,29.14 %). Multiple most common reason for tooth loss were dental caries and periodontal disease (117,33.43 %). Partial edentulism in maxillary arch only 112(32%), in mandibular arch only 172(49.14%) and in both arches 66(18.86%). Kennedy’s Class III type of edentulism was most common in both maxillary arch 104 and mandibular arch 157. Conclusion: Kennedy’s Class III is most common type of partial edentulism in both maxillary and mandibular arch. Preventive programs targeted at reducing tooth loss need to be developed and implemented at national level since most prevalent cause of tooth loss is preventable.

Pattern of Tooth Mortality in Patients Attending a Tertiary Dental Care Center: A Descriptive Study

Background: Tooth loss is a cumulative index of oral health impairment and an integral part of the decayed, missing, and filled teeth index used to assess oral health status. In spite of the increased awareness of oral hygiene and preventive dental treatments, tooth extraction remains to be the most common procedure in the Indian population following a toothache. The study aims to assess certain demographic characteristics and patterns of tooth loss among patients who underwent extraction from the department of oral and maxillofacial surgery in a dental tertiary care center in Kerala, India. Materials and Methods: A retrospective cross-sectional survey was conducted during 2017–2021 time period in all the patients who underwent permanent teeth extraction from the oral and maxillofacial surgery department. Results: A total of 9673 patients underwent tooth extraction during the study period. Among them, 68.4% were adults (18–59 years) and 27.7% were senior adults (above 60 years). More than half of the patients underwent single-tooth extraction (55%), two (24%), and three in 10%. The most frequent tooth extraction was the first molar (30%), followed by the third molar (27%) and second molar (26%). Among children, the most common pattern of tooth extraction was first molars both in the maxilla and mandible (25%). In adolescent age groups, premolars were extracted frequently along with first molars. In adults and senior adults, the premolar and molar extractions were performed commonly. Conclusion: The mean tooth loss for the cohort was 1.7 ± 1.1 (range 1–12) indicative of good dental hygiene practice. The trends noticed in teeth extraction pattern provide baseline data about the access and availability of dental care in that region.

A comparison between rural and urban residents attending Basrah Dental College south of Iraq for tooth extraction between 2018-2021 and its relation to the dental health care situation in Iraq

Most studies confirmed caries are the main cause of tooth extraction in urban and rural areas, especially in young people. There is a relationship between the level of education and dental extraction, particularly in rural areas. In this cross-sectional examination overall 1257 patients were treated in the teaching clinic of the oral and maxillofacial surgery department, College of Dentistry, the University of Basrah between 2018-2021. Data were collected from patients' data after taking the agreement of the ethical committee in the college. The comparisons include age, gender, educational level, occupation, chief complaint, diagnosis and tooth site. reasons and pattern of tooth loss were recorded and data were computed on SPSS. Version 20. The numbers of tooth extraction in urban and rural were very close 632(50.3%) and 624(49.7%) extractions respectively. The male to female percentage was 38.2 %, 61.8% respectively and the highest number of extractions was observed in females in rural areas most of the patients are a housewife. Tooth extraction has seen more in the third, fourth and fifth decade than other age groups 20.4%, 22%, 19.9% respectively. A significant difference between education and dental extraction was noted between urban and rural areas. The main complaint was for prosthetic therapy 45.3% and 43.2% because of pain. The largest proportion considered as the main cause of extraction was dental caries consequences of 80.5% and the lowest 16.9% from periodontal disease. Key Words: Extraction, Rural, Urban, dental health care, First Molar.

Appropriateness of tooth replacement strategies for adult patients in the United Kingdom with reduced dentitions – a modified Delphi analysis

ObjectiveTo develop consensus from experts in Restorative Dentistry based in the United Kingdom (UK) on the most appropriate tooth replacement strategies in adult patients with reduced dentitions using a modified Delphi analysis. MethodsAn expert panel of UK specialists (n=20) in Restorative Dentistry or Prosthodontics were asked to answer the following question: using available evidence and your clinical experience, how appropriate is each tooth replacement strategy for each clinical scenario of tooth loss in the mandible presented? Five specific clinical patterns of tooth loss were presented to panellists using clinical photographs, and using a 9-point Likert scale, they were asked to rate the appropriateness of listed tooth replacement strategies during two Delphi rounds. The target level of consensus for each statement was 70%. ResultsConsensus was reached on the appropriateness of thirty-seven tooth replacement strategies (37%) across ten clinical scenarios. Of these, thirteen were considered appropriate (13%) and twenty-four were considered inappropriate (24%). ConclusionThe results from this Delphi process represent the consensus professional views of an expert panel of UK specialists in Restorative Dentistry and Prosthodontics. Clinical SignificanceTooth replacement for partially dentate patients is a common clinical consideration. This study provides evidence from a Delphi process to help clinicians and patients make informed choices about appropriate and inappropriate treatment options.

Pattern and causes of tooth extraction in patients reporting to GVPIHC and MT, Visakhapatnam, Andhra Pradesh

&lt;p&gt;&lt;strong&gt;Background:&lt;/strong&gt; Teeth help us in masticatory function, phonetics and aesthetics. Loss of teeth may affect quality of life and has significant socioeconomic, psychological consequences. Its important to analyse the reasons and patterns of tooth loss to know their impact on the remaining dentition and oral health. Thus, the present study was designed to understand the pattern and causes of tooth extraction in a targeted population. &lt;strong&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods:&lt;/strong&gt; This retrospective study analysed 972 records of patients who underwent 1092 dental extractions in the department of dentistry at Gayatri Vidya Parishad Institute of Health Care and Medical Technology-Visakhapatnam from January 2021 to December 2021. Various aspects like the causes of extraction, type of teeth extracted, type of dentition involved and site of extraction were evaluated. The collected data was then tabulated and subjected to statistical analysis. &lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results:&lt;/strong&gt; A total of 1092 extractions were evaluated and noticed only 7% cases involving primary dentition. Caries (65.8%) was the most common cause of dental extractions followed by periodontitis. Majority of extractions were noticed in maxillary posterior region. First molars (27.4%) were often extracted followed by second molars. Least number of extractions involved canine.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions:&lt;/strong&gt; Dental caries and periodontitis were the most common causes of dental extraction. Most extractions involved secondary dentition. Maxillary and posterior regions had maximum number of extractions. First molars were commonly extracted followed by second molars. It is necessary to implement preventive dental care programs and improve the oral hygiene awareness in public.&lt;/p&gt;

Prevalence of partial edentulism among the patients visiting a Tertiary Health Care Center in the Western Region, Nepal

Introduction: Tooth loss causes impairment, functional limitation, physical, psychological, and social disability. Hence, the study of pattern of tooth loss can provide a rough information about the frequency, cause and magnitude of oral problems, its sequelae that eventually can act as mirror image of prosthodontic treatment needs. &#x0D; Objectives: To assess the prevalence of partial edentulism and its etiology, to determine its association with sociodemographic parameters, and to find out the motivational factor/s for replacement in willing patients.&#x0D; Methods: Total 417 patients with partial edentulism were examined intraorally on the basis of Kennedy’s classification with Applegate’s modification. The descriptive analysis was done using frequency distribution. Pearson Chi-square analysis test was used to determine the association between demographic variables and type of tooth loss where p-value ≤0.05 was considered statistically significant.&#x0D; Results: Partial edentulism was more prevalent in mandibular arch (41.7%) followed by both arches (30.9%). Kennedy’s Class III was the commonest and Kennedy’s class III modification 1 was second most common type of partial edentulism. Age and educational status had statistically significant association while gender had no association with various classes of partial edentulism. Dental caries (62.8%) followed by periodontitis (25.9%) were the major causes of tooth loss. Functional demand (46.8%) was the key motivational factor for the replacement among those who were willing (78.4%).&#x0D; Conclusions: This study can help in assessing the epidemiological features of partial edentulism of one community in a more classified form and can help gather information necessary to assess the treatment needs.&#x0D;

Tooth Loss Patterns in Hypertensive Patients with Chronic Periodontitis

Aim: The aim of the study is to study the tooth loss pattern in patients with chronic periodontitis and hypertension.&#x0D; Study Design: Retrospective cohort study.&#x0D; Materials and Methods: The case sheet records (DIAS data) of tooth loss pattern in hypertensive patients with chronic periodontitis were extracted. A total of 1318 case sheets were analysed for the study. Age, gender and tooth loss pattern with respect to the region were collected and statistically analysed. Descriptive statistics (Percentage, Mean, Standard deviation) and Inferential test (Chi- square test) were performed to determine the association between age, gender and tooth loss pattern in patients with chronic periodontitis and hypertension.&#x0D; Results: The results showed that that females were affected more with tooth loss with hypertension with chronic periodontitis when compared to males. According to age, patients between 50 to 70 years with chronic periodontitis and hypertension were more affected by tooth loss (p value = 0.001 (p&lt;0.05; Statistically significant)).&#x0D; Conclusion: The present study highlighted a possible relationship between hypertension and tooth loss due to chronic periodontitis. Loss of mandibular posterior teeth were more common and females were more prone to tooth loss than males with hypertension due to chronic periodontitis. However, the underlying mechanism has to be further investigated in a different study design, thus more conclusive findings would be elucidated.

Tooth Loss Patterns in Patients with Periodontitis and Diabetes Mellitus

Aim: Periodontitis is an inflammatory, multifactorial disease which results in destruction of supporting tissue and bone thereby resulting in loosening of the tooth. Tooth loss is one of the major oral issues faced by elderly patients. Thus the present study aimed to investigate the prevalence of tooth loss among periodontitis patients.&#x0D; Methodology: Data collection was conducted from June 2020 to March 2021 among 200 periodontitis patients with diabetes mellitus based on the record management system software to analyse the most frequent missing tooth at the time of first visit. Frequency of maxillary anterior, maxillary posterior, mandibular anterior and mandibular posterior tooth loss was assessed in the study.&#x0D; Results: Among the frequency distribution the mandibular posterior tooth loss was the most common among periodontitis with diabetes patients. In case of anterior tooth loss the results were almost similar with 16% of maxillary anterior tooth loss and 17% in case of mandibular anterior tooth loss. Male subjects presented with more missing teeth in mandibular posterior tooth region when compared to females but not statistically significant (p&gt;0.05).&#x0D; Conclusion: The present study results showed that there is no significant association between sex and maxillary anterior, mandibular anterior, maxillary posterior and mandibular posterior tooth loss (p&gt;0.05). The present study showed that mandibular posterior tooth loss was most frequent among periodontitis with diabetes mellitus patients.

Patterns of Antemortem Tooth Loss in Late Prehistoric West-central Tennessee

The later prehistoric subsistence-settlement pattern in the Kentucky Lake Reservoir (KLR) of northern west-central Tennessee is of interest as human occupation inexplicably terminates by AD 1450 as part of a larger regional depopulation. Antemortem tooth loss (ATL) collectively and by tooth type was identified in four site samples from the KLR. These are a Late Woodland (AD 600-900) sample (Hobbs) and three Middle Mississippian period (AD 1100- 1400) hierarchically organized and presumptively maize agriculturalist samples (Link/Slayden, Gray Farm , Thompson Village). ATL prevalence in the Hobbs sample is consistent with a native crop and seasonal foraging economy. The ATL in the Link sample is more congruent with the pre-maize Late Woodland sample than the essentially contemporaneous Gray Farm site sample. Thompson Village, a later-dated satellite community of the Gray Farm polity, exhibits significantly fewer ATL than the Gray Farm sample. This may flag climate-influenced agricultural shortfall of dietary carbohydrates later in the occupation sequence. Additionally, males in the Gray Farm site sample have significantly more ATL than males in the other two Mississippian samples. The patterns suggest regional, possibly shortfall mitigated, differences in maize intensification with a polity-specific male-focused maize consumption in the Gray Site.

Impacts of Tooth Loss on OHRQoL in an Adult Population in Cape Town, South Africa.

(1) Background: Tooth loss is an important component of the global burden of oral disease, greatly reducing the quality of life of those affected. Tooth loss can also affect diet and subsequent incidences of lifestyle diseases, such as hypertension and metabolic syndromes. This study aimed to evaluate the oral health-related quality of life (OHRQoL) score using the oral impacts on daily performance (OIDP) index in relation to tooth loss patterns among adults. (2) Methods: From 2014 to 2016, a cross-sectional study was conducted on adults living in Bellville South, Cape Town, South Africa. The OHRQoL measure was used to evaluate the impact of tooth loss. (3) Results: A total of 1615 participants were included, and 143 (8.85%) had at least one impact (OIDP > 0). Males were less likely to experience at least one impact compared to the females, OR=0.6, 95% C.I.: 0.385 to 0.942, p = 0.026. Those participants who did not seek dental help due to financial constraints were 6.54 (4.49 to 9.54) times more likely to experience at least one impact, p < 0.001. (4) Conclusions: Tooth loss did not impact the OHRQoL of these subjects. There was no difference in the reported odds for participants experiencing at least one oral impact with the loss of their four anterior teeth, the loss of their posterior occlusal pairs, or the loss of their other teeth.

Macroevolutionary dynamics of dentition in Mesozoic birds reveal no long-term selection towards tooth loss

SummarySeveral potential drivers of avian tooth loss have been proposed, although consensus remains elusive as fully toothless jaws arose independently numerous times among Mesozoic avialans and dinosaurs more broadly. The origin of crown bird edentulism has been discussed in terms of a broad-scale selective pressure or trend toward toothlessness, although this has never been quantitatively tested. Here, we find no evidence for models whereby iterative acquisitions of toothlessness among Mesozoic Avialae were driven by an overarching selective trend. Instead, our results support modularity among jaw regions underlying heterogeneous tooth loss patterns and indicate a substantially later transition to complete crown bird edentulism than previously hypothesized (∼90 mya). We show that patterns of avialan tooth loss adhere to Dollo's law and suggest that the exclusive survival of toothless birds to the present represents lineage-specific selective pressures, irreversibility of tooth loss, and the filter of the Cretaceous-Paleogene (K–Pg) mass extinction.

An overview of oral health status, socio-economic and behavioral risk factors, and the pattern of tooth loss in a sample of Egyptian rural population

BackgroundThe lack of adequate data on the oral health status among the Egyptians is a challenging barrier for the assessment and improvement of oral health needs.ObjectivesThe aim of this study was to collect data on oral health status among a sample of Egyptian rural population and to assess the possible role of the socio-demographic, socio-economic, and behavioral risk factors on the status of the present dentition (the pattern of tooth loss and edentulism).Materials and methodsData was collected from 530 patients with age ranged from 20 to 70 years using a modified World Health Organization (WHO) questionnaire. The questionnaire included information about oral health status, socio-demographic (age and sex), socio-economic (educational levels and income), and behavioral factors (smoking and oral hygiene measures). A complete intra- and extraoral examination and free dental health care services were provided by a team of qualified dental specialists from National Research Centre (NRC). Data was analyzed using chi-square and Spearman’s correlation tests, and the significance level was validated at p < 0.05.ResultsFemales comprised 79% while males were 21% of the surveyed rural sample. Concerning socio-economic aspects including the level of education and income, it was found that 50% of the individuals completed their secondary educational levels, followed by illiterates 35.5% and preparatory levels, while college graduates were minority 4.7%. On the other hand, only 27.5% of rural had income while 72.5% of them had no income. Assessment of behavioral risk factors (oral hygiene procedures and smoking) showed that only 34.3% of the individuals claimed to brush their teeth and only a minority were male smokers (13.8%). The results demonstrated poor oral health status and increased incidence of partial edentulism (45%), where Kennedy class III was the most common type (34.6%).ConclusionsLack of oral hygiene measures specifically tooth brushing is the most significant behavioral risk factor for the poor oral health status and tooth loss in this survey.Sociodemographic and socio-economic factors are influential risk factors for tooth loss.Cigarette smoking was not a main behavioral risk factor that impacts the oral health status in the present survey

New toothed Early Cretaceous ornithuromorph bird reveals intraclade diversity in pattern of tooth loss

The earliest record of the Ornithuromorpha, which includes crown birds, is currently known from the Early Cretaceous Jehol Biota in north-eastern China. Here we describe a new ornithuromorph bird, Mengciusornis dentatus gen. et sp. nov., from the Jiufotang Formation of this biota. Mengciusornis preserves a suite of morphological features exclusively observed among ornithuromorphs in the sympatric taxon Schizooura, including a robust and ‘V’-shaped furcula with a short hypocleidium, and a humerus with a large, rectangular deltopectoral crest in which the distodorsal corner is distinctively developed into a sharp, angular point. The results of our phylogenetic analysis recover these two species together in a clade, positioned stemward within the Ornithuromorpha. Mengciusornis has toothed premaxillae, in stark contrast with the edentulous jaws of Schizooura, demonstrating that dentition varied considerably between some closely related species. Furthermore, all previously known Jehol ornithuromorphs with toothed premaxillae have an edentulous rostral portion of the element, suggesting that tooth loss in this clade proceeded from the rostral end caudally, whereas in Mengciusornis the premaxilla lacks this edentulous rostral tip although the maxilla and dentary are toothless, indicating that the pattern of tooth loss, not unexpectedly, varied between lineages of ornithuromorphs. This observation suggests a strong degree of plasticity in the developmental mechanisms regulating tooth and beak formation, which is supported by earlier evidence that indicates teeth have been lost multiple times within Aves and Dinosauria. Mengciusornis preserves a ventrally hooked scapular acromion that is convergently evolved in parallel with some enantiornithines and neornithines, providing further evidence of the homoplasy that characterizes avian evolution.http://zoobank.org/urn:lsid:zoobank.org:pub:311B34B9-1CBF-47A6-B821-650C04560137
