BackgroundThe rate of total edentulism is said to be increasing in developing countries and this had been attributed mainly to the high prevalence of periodontal diseases and caries. Several reports have shown that non-disease factors such as attitude, behavior, dental attendance, characteristics of health care systems and socio-demographic factors play important roles in the aetiopathogenesis of edentulism. The aim of this study was to assess the relationship between socio-demographic factors and edentulism.MethodsA total of 152 patients made up of 80 (52.6%) males and 72 (47.4%) females who presented in two prosthetic clinics located in an urban and a rural area were included in the study. The relationship between gender, age, socio-economic status and edentulism in this study population was established.ResultsNo significant relationship between gender and denture demand was noted in the study. The demand for complete dentures increased with age while the demand for removable partial dentures also increased with age until the 3rd decade and then started to decline. A significant relationship was found between denture demand and the level of education with a higher demand in lower educational groups (p < 0.001). In addition, the lower socio-economic group had a higher demand more for prostheses than the higher group.ConclusionsThe findings in this study revealed a significant relationship between socio-demographic variables and edentulism with age, educational level and socio-economic status playing vital roles in edentulism and denture demand.

BackgroundThe accuracy of radiographic methods for dental age estimation is important for biological growth research and forensic applications. Accuracy of the two most commonly used systems (Demirjian and Willems) has been evaluated with conflicting results. This study investigates the accuracies of these methods for dental age estimation in different populations.MethodsA search of PubMed, Scopus, Ovid, Database of Open Access Journals and Google Scholar was undertaken. Eligible studies published before December 28, 2016 were reviewed and analyzed. Meta-analysis was performed on 28 published articles using the Demirjian and/or Willems methods to estimate chronological age in 14,109 children (6,581 males, 7,528 females) age 3–18 years in studies using Demirjian’s method and 10,832 children (5,176 males, 5,656 females) age 4–18 years in studies using Willems’ method. The weighted mean difference at 95% confidence interval was used to assess accuracies of the two methods in predicting the chronological age.ResultsThe Demirjian method significantly overestimated chronological age (p<0.05) in males age 3–15 and females age 4–16 when studies were pooled by age cohorts and sex. The majority of studies using Willems’ method did not report significant overestimation of ages in either sex. Overall, Demirjian’s method significantly overestimated chronological age compared to the Willems method (p<0.05). The weighted mean difference for the Demirjian method was 0.62 for males and 0.72 for females, while that of the Willems method was 0.26 for males and 0.29 for females.ConclusionThe Willems method provides more accurate estimation of chronological age in different populations, while Demirjian’s method has a broad application in terms of determining maturity scores. However, accuracy of Demirjian age estimations is confounded by population variation when converting maturity scores to dental ages. For highest accuracy of age estimation, population-specific standards, rather than a universal standard or methods developed on other populations, need to be employed.

Aim There is limited scientific information on the relationship between tooth shade, age, gender, and skin color in black Africans. This lack of knowledge may impact the ability of the prosthodontist to select artificial teeth for completely edentulous patients. This study explores the possibility of a relationship between tooth shade, gender, age, and skin color in a black African population. Methods and Materials A total of 212 individuals aged 15 to 79 years participated in this study. One investigator, calibrated for examining tooth shade, performed all examinations. A Vita-Lumin shade guide was used to examine either the maxillary right or left central incisor. One had to be sound for inclusion in the study. Tooth shades were divided into two categories according to value, and skin tones were divided into two categories (light, and dark). Chi-square analysis and Fisher's exact tests were used to analyze the data (P< 05). Results No statistically significant difference was found between tooth shade and skin color and the subjects’ perception of their tooth shade. However, a statistically significant difference was found between age and tooth shade (P<.001). There was also a statistically significant difference in tooth shade between men and women. Conclusion Within the limitations of this study, tooth shade value and skin color were not related. However, older adults and men are more likely to have darker teeth.

Despite the increase in the consumption of westernised diets by Nigerian children coupled with limited access to dental care, the prevalence was low but the clinical consequences of untreated dental caries was still high.

The prevalence of MIH in this study population is consistent with previous reports. The non-association between sex and MIH prevalence, the varied severity of the lesion and association between MIH affectation of the first permanent molars and central incisors give more weight to the possible role of environmental factors in the aetiology of the lesion. The non-association between MIH and socio-economic status may serve as a distinctive feature of MIH and chronological enamel hypoplasia.

Aim: Maxillectomy often results in a high level of morbidity with significant psychological and functional implications for the patient. Such disabilities include inability to masticate, deglutition, and speech disturbance. Unfortunately, little is known about the nature of the speech disturbance and the influence of the class of surgical defects in this group of patients. The aims of the present study were to assess the effectiveness of the maxillary obturator as a speech rehabilitation aid and to examine the influence of the classes of surgical defects on speech intelligibility (SI). Materials and Methods:Twelve patients aged between 18 and 60 years with surgically acquired partial maxillary defects were included in this study. The patients were given immediate surgical obturators six to ten days after surgery, which were then converted to interim obturators by relining with tissue conditioner. Interim prostheses were used for two to three months until healing and resorption were found satisfactory after which the definitive obturators were fabricated. The SI test described by Plank et al. 1 and Wheeler et al. 8 was employed in this study. There were significant improvements in the mean SI score from 59.8% without prosthetic obturation, to 89.2% following interim obturation, and 94.7% following definitive obturation (p<0.005). Abstract 2Conclusion: Results support the widely held view that the maxillary obturator is a useful speech rehabilitation aid. It also shows immediate, interim, and definitive obturators are all important in the speech rehabilitation of patients with surgically acquired maxillary defects. Moreover SI is affected by the class of defect.

Background:The prevalence of dental caries and its effect on the oral-health-related quality of life (OHRQoL) of children with special needs (CSNs) have not been established in South Africa. Aim:The study aimed to assess how caregivers of CSNs who attended Down Syndrome Association outreach sites in Johannesburg, South Africa, perceived the contribution of OHRQoL to the quality of life of these children. Setting:The study was conducted at Down Syndrome Association (DSA) outreach sites in Johannesburg. These sites cater for children with several types of disabilities including cerebral palsy, hydrocephalus, autism, epilepsy and developmental delays. The association schedules and facilitates support group meetings for the caregivers of children with Down syndrome and other disabilities. These meetings are held at the outreach sites that are located at different district hospitals and community health centres in Johannesburg and are co-facilitated by the association's outreach coordinator together with a team of physiotherapists, occupational therapists and speech therapists. Methods:This cross-sectional study was composed of a convenient sample of 150 caregiver and child pairs from five outreach sites during January -June 2015. The shortform Parent-Caregiver Perception Questionnaire (P-CPQ) was used. The caries status of the children was assessed using the decayed, missing and filled teeth (dmft/DMFT) indices (whereby dmft or DMFT stands for decayed missing filled teeth in primary dentition [dmft] and in permanent dentition [DMFT]) based on World Health Organization guidelines. Results:The mean age of the caregivers was 39.52 years (standard deviation [SD] 9.26) and 8.72 years (SD 6.07) for the children. The mean P-CPQ score was 12.88 (SD 12.14). All the caregivers stated that dental caries had a negative impact on the OHRQoL of the CSNs. However, 60% of caregivers stated that an oral condition had no impact on the child's overall well-being. The majority (56.7%) of the caregivers rated their children's overall oral health status as average and only 12% reported the oral health status to be poor. There was a high prevalence of untreated caries among the CSNs regardless of the type of disability. Conclusion:All the caregivers stated that dental caries had a negative impact on the OHRQoL of the CSNs. However, they appeared to have contradictory perceptions of the oral health needs or status of their children.
