BACKGROUND: Rice is an important dietary source for methylmercury (MeHg), a potent neurotoxin, and inorganic arsenic (As), a human carcinogen. Rice baby cereals are a dietary source of inorganic As; however, less is known concerning MeHg concentrations in rice baby cereals and rice teething biscuits. METHODS: MeHg concentrations were measured in 36 rice baby cereals, eight rice teething biscuits, and four baby cereals manufactured with oats/wheat (n = 48 total)...

OBJECTIVES: To determine: the knowledge of the participants about removable dentures, importance of tooth replacement; prevalence of tooth loss and denture use; and factors associated with its non-use among an elderly population in Nigeria. BACKGROUND: Tooth loss without replacement can impact negatively on the quality of life of the elders, thus making use of denture a basic requirement for those with partial or complete edentulous arches in developed countries...

Multiple supernumerary teeth are rare developmental anomalies which are often associated with syndromes. Only few examples of nonsyndromic supernumerary teeth have been reported with fourth, fifth, sixth, and seventh molar rarest of all. The cause, frequency, complications, and surgical operation of supernumerary teeth are always interesting subjects for study and research. Literature reports increased occurrence of the supernumeraries in the maxilla, but here, a unique and unusual case report of 12-year-old female patient with unilateral multiple impacted supernumerary teeth in the mandible in otherwise healthy individual has been presented...

The mix of bacteria that coat our teeth impact oral health, but it remains unclear what factors govern their composition. In this issue of Cell Host & Microbe, Gomez et al. (2017) examine the relationship between host genetics and the oral microbiome in the context of health and disease.

AIM: This study assessed the long-term annual costs for treating aggressive periodontitis (AgP) patients. METHODS: A cohort of compliant AgP patients was retrospectively evaluated. Costs for active periodontal therapy (APT, including scaling and root planning, open flap debridement, root resections, but not pocket-elimination or regenerative surgery) and supportive periodontal therapy (SPT, including also costs for restorative, endodontic, prosthetic and surgical treatments) were estimated from a mixed payer-perspective in Germany...

Leprosy is a hyperendemic chronic condition in the Rondônia State . Despite the significant impact of oral health on the quality of life and clinical evolution of leprosy patients, systematic evaluation of oral health status has been neglected. To analyze the dental-clinical profile, self-perceived oral health and dental health service access of leprosy cases in the municipality of Cacoal in Rondônia State , North Brazil, from 2001 to 2012. A descriptive, cross-sectional study design was performed based on dental evaluation and standardized structured instruments...

Systematic study of dental attributes yields insights regarding diet and subsistence that cannot be gained from the archaeological record alone. This analysis documents occlusal tooth wear, tooth crown dimensions and dental pathology of an expanded dental sample from Harappa (2550-2030cal BC; Pakistan). New floral and faunal evidence of subsistence indicates a mix of agriculture and pastoralism that can be integrated with evidence of dental attributes and disease to reveal the impact of Harappan diet on oral health...

BACKGROUND: The aim of this study was to compare OPG and CT accuracy in predicting inferior alveolar nerve (IAN) injury after lower wisdom teeth extraction. METHODS: 23 patients with completely impacted lower third molar were enrolled in this study and OPG and CT exams were obtained before surgical intervention. Finally, a total of 26 lower third molars were extracted and cases of paresthesia following a IAN lesion have been registered. Then, OPG and CT images of the same patients have been randomly submitted to four experienced oral surgeons (with a seniority of at least 5 years) who were required to predict the possibility of a IAN injury by only evaluating the radiological exams...

AIM: To compare the prevalence of PEIR in Australian and Saudi Arabian children and to investigate the relationship of PEIR with dental development. STUDY DESIGN: Panoramic (PAN) radiographs of 842 Australian and 456 Saudi children were screened for PEIR. The dental ages of the children with and without PEIR were assessed from the PAN radiographs using the method of Demirjian and co-workers. RESULTS: The subject prevalence of PEIR was not statistically significant between Australian (2%) and Saudi children (0...

Maxillary canines are the most commonly impacted teeth, second only to third molars. Various treatment methods may be used to recover impacted maxillary canines. This is a report of a 14-year-old girl with a severely malpositioned impacted right maxillary canine which accompanied severe root resorption of adjacent tooth, treated by autotransplantation with a computer aided rapid prototyping model as a surgical guide. This case report demonstrates that autotransplantation can be a reliable treatment alternative, in cases with a severely malpositioned impacted canine, providing acceptable prognosis...

The purpose of this study is to compare total and partial larygectomy on private life functions and sexuality in patients with laryngeal cancer. The study included 31 partial laryngectomy patients (Group 1) and 51 total laryngectomy patients (Group 2) who were operated for laryngeal cancer. European Organization for Research and Treatment of Cancer (EORTC) head and neck cancer module (QLQ-H&N35) and Arizona Sexual Experiences Scale (ASEX) forms were filled in by interviewing face to face with patients. HNSW (swallowing), HNSE (senses), HNSP (speech), HNSO (social eating), HNSX (sexuality), HNTE (problems with teeth), HNOM (problems with opening mouth) and HNCO (coughing) scores of EORTC QLQ-H&N35 were significantly higher in group 2 than in group 1...

Fluoride in drinking water has several effects on teeth and bones. At concentrations of 1-1.5 mg/L, fluoride can strengthen enamel, improving dental health, but at concentrations above 1.5 to 4 mg/L can cause dental fluorosis. At concentrations of 4-10 mg/L, skeletal fluorosis can occur. There are many areas of the world that have excessive fluoride in drinking water, such as China, India, Sri Lanka, and the Rift Valley countries in Africa. Treatment solutions are needed, especially in poor areas where drinking water treatment plants are not available...

INTRODUCTION: The aim of the study was to compare the outcomes of regenerative endodontic treatment (RET) and apexification on immature permanent teeth with pulp necrosis and apical periodontitis. METHODS: A total of 118 patients (118 teeth) were recruited and randomly assigned to either RET or apexification treatment. Each treatment group was divided into 2 subgroups according to the etiology: dens evaginatus or trauma. Clinical symptoms and complications were recorded, and cone-beam computed tomographic imaging with a limited field of view was used to measure the change of root length, root thickness, and apical foramen size at the 12-month follow-up...

The technical quality of root canal treatment (RCT) may impact on the outcome. The quality of education received during undergraduate school may be linked to the quality of treatment provided in general dental practice. In this context, the aim of this systematic-review is to answer the following focused questions: 1) What is the frequency of acceptable technical quality of root fillings, assessed radiographically, performed by undergraduate students? 2) What are the most common errors assessed radiographically and reported in these treatments? For this purpose, articles that evaluated the quality of root fillings performed by undergraduate students were selected...

AIM: The aims of the present retrospective study were to evaluate the outcomes of dental extractions in nasopharyngeal carcinoma patients who had undergone dental clearance pre- and post-radiotherapy (RT) with intensity-modulated RT, and to report on the incidence and timing of osteoradionecrosis (ORN) in these patients. METHODS: A total of 231 patients were seen pre-, mid-, and postradiation therapy. Information on patient demographics, smoking history, staging, treatment modalities, dental extraction indications, and number and site of dental extractions was gathered...
