Dental complications of herpes zoster: Two case reports and review of literature
We report two such rare dental complications of HZ-spontaneous tooth exfoliation and osteonecrosis of the maxilla in a 70-year-old female patient; and multiple periapical pathoses affecting right half of the mandibular teeth in a 45-year-old female patient. Both the patients did not have any associated systemic illness. The aim of this paper was to compare the present cases with all the 46 cases of osteonecrosis and 6 cases of multiple periapical pathoses secondary to trigeminal zoster reported in literature till date The article also throws light that the occurrence of such dental complications of HZ is not entirely depen...

A simple ear splint for microtia patients
CJ Venkata Krishnan, SM Balaji, Ashish R JainIndian Journal of Dental Research 2015 26(2):220-221Microtia is a congenital anomaly of the ear can occur as an isolated birth defect or as part of a spectrum of anomalies or as a syndrome. Microtia is often associated with impaired hearing and or total loss of hearing. Such patients typically require treatment for surgical ear reconstruction and for hearing impairment. Maintenance of ear projection and post auricular sulcus in staged ear reconstruction in microtia is a trying problem. So also is the maintenance of the patency of the external auditory meatus following recanaliza...

Cone Beam Computed Tomography evaluation of palatal bone thickness for miniscrew placement in Down's syndrome
Down's syndrome (DS) is characterised by the presence of an extra copy of the genetic material of chromosome 21. It is the most common chromosomal abnormality, with an incidence of approximate 1 in 600 live births 1. The advances in specific medical care and social integration programmes in recent decades have contributed to an increase in the quality of life and life expectancy of individuals with DS 2,3 and this has increased the need for oral health care in this population 4,5.

Antioxidant profile, carbonyl and lipid oxidation markers in the parotid and submandibular glands of rats in different periods of streptozotocin induced diabetes
Diabetes mellitus type 1 is a metabolic disease which is characterized by hyperglycemia resulting from disturbances of insulin secretion or its action in target cells1. A chronic hyperglycemia in the course of diabetes type 1 results in morphological changes and dysfunction various organs including salivary glands. It was described that diabetic parotid, but not sublingual and submandibular, swelling was caused by the hydropic degeneration of its ductal and acinar cells. Moreover Carda et al.2 showed that this increase in glandular size was due to adipose parotid stroma infiltration and ductal dilatation. (Source: Archives of Oral Biology)

The role of matrix metalloproteinases and cysteine-cathepsins on the progression of dentine erosion
The marked role of fluoride (F) in preventing dental caries, producing a favorable balance in tooth de- and remineralisation, has been well established.1 However, its action on the prevention of dentine erosion seems to depend on the maintenance of the demineralised organic matrix (DOM).2 The maintenance of the DOM after erosive demineralisation may be important to prevent or reduce further demineralisation, slowing down ionic diffusion to and from the demineralising area.3,4 DOM is susceptible to breakdown by host-derived salivary or endogenous dentinal enzymes, including matrix metalloproteinases (MMPs)5–7 and cysteine...

Infraocclusion: Dental development and associated dental variations in singletons and twins
Developmental variations may affect the number, size, shape, mineralisation and eruption of teeth.1–4 ‘Infraocclusion’ is a disturbance in the ongoing eruption process, resulting in a tooth that is positioned below the level of occlusion. Most teeth that show infraocclusion have erupted to the normal plane of occlusion and then stopped erupting while the adjacent teeth have continued to erupt. Occasionally there may have been primary eruption failure causing teeth to never reach the plane of occlusion,4,5 but without comprehensive longitudinal data this cannot be determined with certainty.

Assessment of masticatory muscle activity and occlusion time in patients with advanced tooth wear
Tooth wear is often a basic physiological adjustment mechanism in masticatory system and it is a recognized physiological, irreversible process. However, there are individuals in whom the phenomenon of wear occurs dramatically faster and, if not treated, may lead to the complete destruction of the system.1–3 A clinical view of occlusal wear customarily reveals flattening of the occlusal surfaces, the presence of enamel discoloration, cracks and fractures, dentine exposure, sharp and uneven incisal edges, short clinical tooth crowns and in the worst cases, pulp exposure.

Reducing Inequalities in Oral Health in the Africa and Middle East Region
Dentistry is facing many serious challenges and threats. Addressing them will require major changes in strategy. This work outlines the extent of dental disease in the Africa and Middle East Region (AMER) and suggests strategies to reduce inequalities in oral health. The main oral health challenges in the AMER relate to controlling the relentless increase in caries with age. A very conservative estimate of population caries levels suggests that a 5-fold increase in dental personnel would be required just to treat current levels of caries. Hence, we argue that current approaches to control caries in the AMER are both ineffe...

Prevalence and Severity of Oral Diseases in the Africa and Middle East Region
This review aims to determine the prevalence and severity of oral health diseases in the Africa and Middle East region (AMER). The profile of oral diseases is not homogeneous across the AMER. There are large disparities between groups. Reliable data are scarce. The prevalence and severity of oral diseases appear to be increasing in the African region, as does associated morbidity. There are substantial differences in inequalities in oral health. Dental caries prevalence is less severe in most African countries than in developed countries, but the high rate of untreated caries reflects the limited resources available and di...

Oral Health Inequalities between Rural and Urban Populations of the African and Middle East Region
Although there have been major improvements in oral health, with remarkable advances in the prevention and management of oral diseases, globally, inequalities persist between urban and rural communities. These inequalities exist in the distribution of oral health services, accessibility, utilization, treatment outcomes, oral health knowledge and practices, health insurance coverage, oral health–related quality of life, and prevalence of oral diseases, among others. People living in rural areas are likely to be poorer, be less health literate, have more caries, have fewer teeth, have no health insurance coverage, and ...

Determinants of Oral Diseases in the African and Middle East Region
Oral health policies must be developed that emphasize the role of social determinants in health and oral diseases. The aim of this report is to review literature on determinants of oral diseases and apply the concepts to promoting oral health in the African countries in the African and Middle East region (AMER). Structural and proximal determinants of oral diseases are common to those affected by other noncommunicable diseases (NCDs). Oral diseases are also heavily affected by issues of politics, poor health behaviors, underdeveloped health systems, and low oral health literacy. Wide-scale poverty exists in populations in ...

Capacity Building and Financing Oral Health in the African and Middle East Region
Many low- and middle-income countries do not yet have policies to implement effective oral health programs. A reason is lack of human and financial resources. Gaps between resource needs and available health funding are widening. By building capacity, countries aim to improve oral health through actions by oral health care personnel and oral health care organizations and their communities. Capacity building involves achieving measurable and sustainable results in training, research, and provision of care. Actions include advancement of knowledge, attitudes and skills, expansion of support, and development of cohesiveness a...

Early detection of pulp necrosis and dental vitality after traumatic dental injuries in children and adolescents by 3-Tesla magnetic resonance imaging
Conclusion 3T MRI is a very promising tool for visualization and detection in the field of dental and oromaxillofacial diseases. By using new 3T MRI sequences in children with TDI, we could demonstrate that RCT are not necessary in every case, and thus could prevent unnecessary treatment of children in the future. Larger studies should follow to confirm the potential benefit in clinical practice. (Source: Journal of Cranio Maxillofacial Surgery)

Fixed functional appliances show definite skeletal and dental changes in the short term.
Abstract SummaryA meta-analysis of the literature on fixed functional appliances found nine unique data sets (n = 418 patients, mean age = 13.2 years) that fulfilled the criteria. Small but statistically significant changes in SNA, SNB, and ANB occurred, with larger changes in the incisor angulations. The results are compared with a previous meta-analysis on the effects of removable functional appliances by the same team and discussed in regard to their implications for clinical practice.

Electronic assessment of peri‐implant mucosal esthetics around three implant–abutment configurations: a randomized clinical trial
ConclusionsNo significant differences in mean sum PESs were found between subjects randomized to three different implant–abutment interfaces. However, significant differences were found as a function of time for all three groups, with the largest improvement in mean sum PESs occurring between definitive abutment and restoration delivery and 6 months. Use of electronic, tablet‐based digital imaging scoring formats represents a novel and repeatable methodology for scoring PES images in large, multicenter clinical trials.

Depolarization-induced Intracellular Free Calcium Concentration Increases Show No Desensitizing Effect in Rat Odontoblasts.
Abstract Odontoblasts play an important role in the transduction of the sensory signals underlying dentinal pain. Transmembrane voltage-independent Ca(2+) influx in odontoblasts has been well described. Voltage-dependent Ca(2+) influx has also been reported, but its biophysical properties remain unclear. The aim of the present study was to investigate the desensitizing effect of voltage-dependent Ca(2+) influx in rat odontoblasts by measuring depolarization-induced intracellular free Ca(2+) concentrations ([Ca(2+) ]i ). Odontoblasts on dental pulp slices from newborn rats were acutely isolated and [Ca(2+) ]i measur...

A Case of Infratemporal Fossa Abscess with Signs of Chronic Maxillary Osteomyelitis.
We report an extremely rare case of an infratemporal fossa abscess arising from chronic maxillary osteomyelitis developing after extraction of a maxillary molar. Despite drainage during initial oral anti-inflammatory treatment, pus continued to drain from the wound over a long period of time. This drainage ended when the eroded bone of the maxillary tuberosity on the affected side was curetted in a secondary procedure. The harvested bone tissue exhibited histological findings of chronic osteomyelitis. This suggests that the route of infection involved acute transformation of maxillary osteomyelitis by odontogenic infection...

Glucose-PTS Involvement in Maltose Metabolism by Streptococcus mutans.
Abstract Streptococcus mutans grows with starch-derived maltose in the presence of saliva. Maltose transported into the cells is mediated by the MalQ protein (4-alpha-glucanotransferase) to produce glucose and maltooligosaccharides. Glucose can be phosphorylated to glucose 6-phosphate, which can enter the glycolysis pathway. The MalQ enzyme is essential in the catabolism of maltose when it is the sole carbon source, suggesting the presence of a downstream glucokinase of the MalQ enzyme reaction. However, a glucokinase gene-inactivated mutant (glk mutant) grew with maltose as the sole carbon source, with no residual...

Inhibitory effects of oral on the proliferation, virulence and biofilm formation of
Excessive antibiotic use and long-term denture wearing are the most common reasons for Candida-associated stomatitis, the pathogenesis of which still requires clarification. Some evidence suggests that it involves the dysfunction of oral flora antagonistic to Candida as the development of oral candidiasis sometimes occurs after long-term antibiotic use. Long-term broad-spectrum antibiotic therapy might kill or inhibit the flora antagonistic to Candida, resulting in excessive multiplication of Candida and the consequent development of antibiotic-associated stomatitis.

Responses of Human Dental Pulp Cells after Application of a Low-concentration Bleaching Gel to Enamel
It is well known that tooth-bleaching therapy can promote odontoblast death due to oxidative damage mediated by hydrogen peroxide and its by-products, capable of diffusing through enamel and dentin at toxic concentrations.1,2 These cells are essential for the homeostasis of the dentin-pulp complex, since they are responsible for the deposition and mineralization of dentin matrix throughout the life of the tooth, as well as for the orchestration of the inflammatory and immune responses of pulp tissue, since the noxious signal acts on the tooth surface.

Decrease of miR-146a is associated with the aggressiveness of human oral squamous cell carcinoma
Cancer of oral cavity is one of the most common malignancies worldwide, with 640,000 new diagnoses and more than 200,000 deaths worldwide annually 1–3. About 40% of all oral cancers occur in the tongue, where tumors frequently remain undetected until advanced stage. Patients with tongue cancer have a poorer survival rate relative to other anatomic sites in the oral cavity. Oral squamous cell carcinoma (OSCC) is the most common histopathologic type. The propensity for aggressive invasion and metastasis in OSCC pose a great challenge for clinical management. (Source: Archives of Oral Biology)

Mild Hypodontia is associated with smaller tooth dimensions and cusp numbers than in controls
Dental development is a Complex Adaptive System which regulates the initiation and morphogenesis of tooth germs by a series of interactions between genetic, epigenetic and environmental factors that determine tooth number, location, type, size and morphology . Within this system hypodontia and its associated clinical features arise from a multifactorial aetiology [1–5]. Dental anomalies affecting tooth morphology may influence the function of the dento-maxillary system. Congenitally missing teeth have not only functional, but also aesthetic and psychological effects on the patient and influence orthodontic treatment. ...
