The review summarizes the current understanding of dental health in children with chronic kidney disease (CKD). Oral conditions associated with CKD and its medical and surgical management have been described in cohort studies. Children with CKD may present with severe developmental defects of enamel (DDE) including discoloration, pitting, and reduced hardness leading to extensive tooth wear with normal function. The alkaline oral pH resulting from the uremia of CKD inhibits cariogenic bacteria, reduces dental caries risk, and increases accumulation of dental calculus. The malnutrition, acidosis, growth hormone resistance, anemia, and renal osteodystrophy in CKD provide multiple mechanisms for abnormal craniofacial growth and delayed tooth eruption. Following successful kidney transplant, caries risk increases due to normalization of oral pH in the presence of DDE; optimized diet and oral hygiene become critical in caries control. Post-transplant medications including cyclosporine A and calcium channel blockers may cause gingival overgrowth which in severe cases requires gingival surgery to allow tooth eruption, improve appearance, or permit orthodontic treatment. Immune suppression with sirolimus or everolimus may cause severe debilitating oral ulcerations. Long-term immune suppression increases the risk for development of oral candidiasis and oral cancers. Dental examinations and treatment are recommended for children with all stages of CKD to mitigate adverse oral outcomes of the disease and its management.

Reconstructing diet can offer an improved understanding toward the origin and evolution of modern humans. However, the diet of early modern humans in East Asia is poorly understood. Starch analysis of dental calculus is harmless to precious fossil hominins and provides the most direct evidence of plant food sources in early modern human dietary records. In this paper, we examined the starch grains in dental calculus from Fuyan Cave hominins in Daoxian (South China), which were the earliest modern humans in East Asia. Our results reveal the earliest direct evidence of a hominin diet made of acorns, roots, tubers, grass seeds, and other yet-unidentified plants in marine isotope stage 5 between 120 and 80 ka. Our study also provides the earliest evidence that acorns may have played an important role in subsistence strategies. There may have been a long-lasting tradition of using these plants during the Late Pleistocene in China. Plant foods would have been a plentiful source of carbohydrates that greatly increased energy availability to human tissues with high glucose demands. Our study provides the earliest direct consumption of carbohydrates-rich plant resources from modern humans in China for the first time. In addition, it also helps elucidate the evolutionary advantages of early modern humans in the late Middle and early Upper Pleistocene.

Despite being one of the most important crops in the recent prehistory of Eurasia, the arrival and exploitation of millets in the westernmost part of Europe are still largely underexplored. Here and for the first time, we report multipronged biomolecular evidence of millet consumption along the Atlantic façade of northern Iberia through a combination of radiocarbon dating, stable isotopes, and dental calculus analyses on the human individuals found in the burial site of El Espinoso cave (Asturias, Spain). The high-resolution chronological framework established for individuals placed the burials between 1235 and 1099 cal. BC. The discovery of high δC values on their bone collagen and the identification of polyhedral starch grains within their dental plaque underline the relevance of C plants in their diet and highlights the timing of the systematic consumption of millets in the Late Bronze Age. Our data support previous regional archaeobotanical evidence and establish a more precise chronology of the dispersal of millets into northern Iberia during the Bronze Age, becoming an essential crop until the arrival of maize from America after AD 1492. This study emphasizes the importance of multidisciplinary methods to ascertain the origin and development of agricultural practices during recent prehistory.

Journal of Oral Science Jul 2022The purpose of this repeated cross-sectional study was to investigate the prevalence and severity of oral hygiene conditions in Cambodian primary school children.
PURPOSE
The purpose of this repeated cross-sectional study was to investigate the prevalence and severity of oral hygiene conditions in Cambodian primary school children.
METHODS
Oral examinations were conducted on 2,020 school children (1st-6th grade) at a public primary school in Siem Reap, Cambodia from 2013 to 2015, focusing on plaque adhesion, gingiva, and dental calculus deposition. Data analysis was performed on 1,998 children without any missing data, and the chi-square test was used to compare the variables.
RESULTS
The prevalence of dental plaque adhesion in 2013, 2014, and 2015 was 93.6%, 93.7%, and 85.1%, respectively. The prevalence of gingivitis in 2013, 2014, and 2015 was 93.1%, 92.1%, and 88.8%, respectively. The prevalence of dental calculus deposition in 2013, 2014, and 2015 was 55.1%, 19.3%, and 34.7%, respectively. Significant differences were observed in all variables each year (P < 0.001).
CONCLUSION
The findings of this study suggest that oral hygiene conditions were poor in this population.

Community Dentistry and Oral... Aug 2022To investigate alveolar bone loss (ABL), which is an indicator of periodontitis, and to identify risk factors for ABL in an older population between 2008 and 2018.
OBJECTIVES
To investigate alveolar bone loss (ABL), which is an indicator of periodontitis, and to identify risk factors for ABL in an older population between 2008 and 2018.
METHODS
This longitudinal study used data from a questionnaire survey and a clinical examination administered on two occasions ten years apart to 273 individuals who were 65 years and 75 years in 2008.
RESULTS
The mean number of teeth decreased significantly over the ten-year study period, while the proportion of individuals with calculus and moderate ABL visible on radiographs increased. For both ages, the number of teeth decreased by a mean of 2 teeth. The proportions of participants reporting poor general health, daily medication, xerostomia, living singly, visiting dental care irregularly and being in need of extra support in their homes all increased over the observation period.
CONCLUSIONS
Despite an increased progression of moderate alveolar bone loss, a fairly good dentition and chewing capacity was retained in this older population. However, the individual's age and fragility are important indicators that need to be considered when planning oral health care and the availability of dental care.

Numerous oral changes develop as a result of dysfunctional eating behavior in patients with eating disorders (ED). The aim of this study was to evaluate the correlation among oral manifestations, age, disease duration and nutritional status in pediatric patients with ED. The study included 50 female ED patients, median age 14 (range 10-18) years and median disease duration 9 (range 1-42) months. Nutritional status was expressed as z-score for body mass index (BMI). Mean BMI z-score was -2.10±1.64. The most commonly observed oral findings were dental plaque, marginal gingivitis, morsicatio, dental calculus, caries, pharyngeal erythema, exfoliative cheilitis and angular cheilitis. Dental plaque and pharyngeal erythema were correlated with shorter disease duration (p=0.048; p=0.040), while frictional keratosis of tongue was correlated with longer disease duration (0.011). Linea alba and pain in the temporomandibular joint were associated with younger age (p=0.012; p=0.024), and tooth impression on tongue with lower degree of nutrition (p=0.030). This study showed that there was a link among oral manifestations, age, disease duration and degree of nutritional disorder, although further investigations comparing the groups of ED patients with different age, disease duration and nutritional status would give better, concrete and precise conclusions.

BACKGROUND
Calculus accumulation varies widely between individuals. Dental calculus has been associated with the principal periodontal diseases. The aim of this study was to analyze individual characteristics, and salivary and microbiological parameters among patients considered to be rapid calculus formers and patients who form calculus slowly.
METHODS
Individual characteristics were recorded in a sample of 74 patients (age, sex, smoking, periodontal diagnosis, and dental crowding), as well as salivary parameters (unstimulated saliva flow, pH, and biochemical analysis of saliva) and microbiological parameters (by means of semi-quantitative polymerase chain reaction (PCR) analysis).
RESULTS
A statistically significant association ( = 0.002) was found between the rate of calculus formation and the diagnosis of periodontal disease. A greater presence of dental crowding was observed among the group of rapid calculus formers. Urea and phosphorus levels were higher among rapid calculus formers. Regarding microbiological parameters, differences were found in , this being higher in the group of slow formers.
CONCLUSIONS
Rapid calculus formation appears to be linked to patients diagnosed with more severe periodontal diseases. Rapid calculus-forming patients present more dental crowding and a lower proportion of .

The COVID-19 pandemic significantly impacted the healthcare system, including dentistry. However, it is not entirely clear whether affected patients' willingness for regular dental visits and preventive behaviors with regards oral hygiene and diet. This is essential to understanding the potential effects of the COVID-19 pandemic on the acceleration of dental issues in the future. It was aimed at checking the level of dental visit avoidance, self-reported oral health needs, and dietary changes. This cross-sectional questionnaire study conducted in Poland ( = 2574; mean age 44.4 ± 15.6; female 56.3%) assessed nutritional habits and dental care changes during the COVID-19 pandemic. As demonstrated, nearly half of the responders (47.1%) avoided regular dental visits, while only 0.5% used online consultations. Fears related to potential cross-contamination in dental offices dropped from 25% to 11.4% and were associated with increased BMI and age ( < 0.05). Sweet snacking/drinking confirmed 19.1%/33.2% subjects. Self-reported oral health care needs (tooth stain, calculus, gingivitis, loss of fillings) were related to frequent snacking and poor oral hygiene ( < 0.05). The study highlights that pandemic periods are covered by eating and drinking changes combined with inadequate hygiene and dental care impose health complaints in the oral cavity. This can magnify both nutritional and interrelated oral health issues, highlighting the need to implement preventive and mitigation measures.

BACKGROUND
Gingivitis is a common oral health problem, and untreated gingivitis can progress to periodontitis. The objectives of this study were to (1) explore associated factors of gingival bleeding and calculus among 12-year-old adolescents; (2) find predictive models for gingivitis management.
METHODS
Four thousand five hundred twenty-five subjects aged 12 in Sichuan Province were investigated. The questionnaire and clinical examination were applied in schools, and two-level logistic regression models were constructed to interpret the effect of individual and contextual factors on Chinese adolescents' gingival bleeding and calculus.
RESULTS
46.63% (95%CI: 40.71, 51.60) and 66.94% (95%CI: 56.85, 67.45) of the subjects presented gingival bleeding and calculus, respectively. For the gingival bleeding cases, the model showed the significant associated indicators were hukou (OR = 0.61, 95% CI: 0.52-0.72), family size (OR = 1.41, 95% CI: 1.19-1.68), parental educational level (father: OR = 0.53, 95% CI: 0.45-0.63; mother: OR = 0.71, 95% CI: 0.59-0.86), tooth-brushing frequency (OR = 0.35, 95% CI: 0.26-0.48), dental floss use (OR = 0.58, 95% CI: 0.41-0.83), sugar-containing drink consumption (OR = 2.11, 95% CI: 1.80-2.49), and dental visit (OR = 1.44, 95% CI: 1.19-1.74). It also confirmed that gender (OR = 1.32, 95% CI: 1.13-1.54), hukou (OR = 0.69, 95% CI: 0.59-0.82), family size (OR = 1.34, 95% CI: 1.12-1.59), parental educational level (father: OR = 0.46, 95% CI: 0.39-0.54; mother: OR = 0.65, 95% CI: 0.59-0.82), tooth-brushing frequency (OR = 0.57, 95% CI: 0.42-0.78), dental floss use (OR = 0.66, 95% CI: 0.48-0.90) and sugar-containing drink consumption (OR = 1.30, 95% CI: 1.11-1.53) were associated factors for dental calculus.
CONCLUSIONS
Gingival bleeding and calculus were common in western Chinese adolescents. Socio-demographic factors including gender, hukou and family factors are strong determinants of gingival health in Chinese adolescents. In addition, health-related lifestyle behaviors such as healthy diet, good hygiene care and more dental visits are good predictors of better gingival status.

Review
This targeted review of oral paleopathology in the Central Andes explores research that focuses on a set of interrelated, multifactorial processes: dental caries, macrowear, alveolar abscess, antemortem tooth loss (AMTL), periodontal disease, and the presence of dental calculus. These conditions help characterize oral health because they result from the culturally mediated interaction of individuals' oral cavity with their external environment. To better understand how osteologists working in the Central Andes have interpreted the frequencies of these conditions, I review the etiology of each, as well as discuss the important issues in their analyses. I then highlight studies that integrate of a number of oral paleopathological conditions, that examine associations between oral conditions and other skeletal indicators of health, or that use multivariate statistical techniques to analyze conditions. In the Central Andes, these proxies for oral health have generally focused on several key research themes including the introduction of domesticated foods may have occurred earlier than expected, but that populations may have maintained mixed subsistence strategies for a significant period. Researchers have also identified that changes accompanying Inca imperialism were likely not as detrimental to local populations as was Spanish colonialism. Finally, the long-practiced, culturally important, activity of chewing coca has been shown to create an identifiable pattern of oral paleopathological conditions.
