AIM: To analyse differences in the eruption of primary teeth between both sexes. MATERIALS AND METHODS: A cross-sectional study was performed in a sample of 1250 children aged between 3 and 42 months. The clinical emergence of teeth was taken to estimate average ages for primary teeth eruption. The t-test was used to analyse gender and arch differences. RESULTS: Eruption of primary teeth began at the same time in girls as in boys; although the eruptive process was longer in girls...

The Nyvad classification is a visual-tactile caries classification system devised to enable the detection of the activity and severity of caries lesions with special focus on low-caries populations. The criteria behind the classification reflect the entire continuum of caries, ranging from clinically sound surfaces through noncavitated and microcavitated caries lesions in enamel, to frank cavitation into the dentin. Lesion activity at each severity stage is discriminated by differences in surface topography and lesion texture...

BACKGROUND/AIMS: Traumatic dental injuries of primary-dentition (TDI-p) have a global prevalence of approximately 11-47%. They have immediate and long term effects. Original research analysing the long-term sequelae of TDI-p on permanent-dentition (LSP) are few in number. The aim of this study was to explore the correlation between age of TDI-p, type of TDI-p and LSP. MATERIAL AND METHODS: Retrospective analysis of patient-data from 2008-2017, reporting with LSP due to TDI-p was performed...

Regional odontodysplasia (RO) also known as ghost teeth is a rare developmental anomaly affecting the mesodermal and ectodermal components of teeth with characteristic clinical and radiographic findings. The enamel and dentin are hypomineralized and hypocalcified with short roots and open apices. The affected teeth have an abnormal morphology, meaning they are fragile and thin and liable to fracture and decay. Radiographically, there is a marked reduction in radiodensity with little distinction between the enamel and dentin, hence the term "ghost teeth...

BACKGROUND/AIM: Studies reveal many dental students and general dentists have inadequate knowledge about treating children who sustain traumatic dental injuries. The aims of this study were to assess dental trauma knowledge amongst novice clinicians and expert pediatric dentists and determine the effectiveness of a clinical decision support tool (CDST) for the management of trauma scenarios. A secondary purpose was to compare the effects of a print and mobile app format of the CDST. METHODS: A print and mobile app CDST was developed based upon current AAPD and IADT clinical guidelines...

Since the classical epidemiological studies by Dean, it has been known that there should be an optimum level of exposure to fluoride that would be able to provide the maximum protection against caries, with minimum dental fluorosis. The "optimal" daily intake of fluoride for children (0.05-0.07 mg per kilogram bodyweight) that is still accepted worldwide was empirically determined. In the present review, we discuss the appropriateness of the current guidance for fluoride intake, in light of the windows of susceptibility to caries and fluorosis, the modern trends of fluoride intake from multiple sources, individual variations in fluoride metabolism, and recent epidemiological data...

Traumatic dental injuries (TDIs) account for a considerable proportion of bodily injuries. Nevertheless, global TDI frequency is unknown, probably because TDI diagnosis is not standardized. This study estimated world TDI frequency. A literature search (publication years 1996-2016) was aimed at covering as many countries, communities, ethnic groups as possible, thus achieving high generalizability. In particular, nonspecific keywords, no language restrictions and large databanks were used. Observational studies reporting proportions of individuals with at least one TDI (prevalence) and who developed TDI (incidence rate) were considered...

Identification of victims in a disaster is a challenging process and requires use of both primary and secondary identifiers. Development of teeth is one of the routinely used methods of age estimation and helps in establishing deceased biological profile. Two children who lost their lives in 2014 in Nepal Airlines crash, were looked for the dental developmental status. One of the children had primary dentition, while the other had mixed dentition. This helped us in estimating age of these individuals reconciled with the chronological age provided by the relatives...

A diagnosis of head and neck cancer (HNC) is typically followed by therapy that is associated with immediate and long-lasting toxic consequences. HNC patients' oral health needs may be complex and are best addressed in multidisciplinary collaborative teams including surgical, medical, and radiation oncologists, dental providers, nutrition, speech/swallow specialists, and physical therapists. Oral health maintenance also requires patient compliance and caregiver support. The role of dental providers begins prior to cancer diagnosis and continues through survivorship...

Aim: Maintenance of primary dentition is imperative for the development of arch form, esthetics, function, mastication, and normal eruption of permanent teeth. Premature loss can cause various problems such as ectopic eruption, space loss for the successor permanent teeth, alterations in speech, and impairment of function. Hence, decayed primary teeth should not be extracted and treated whenever possible. Pulpectomy is generally recommended as a treatment of choice in such cases. The purpose of this study was to evaluate the clinical and radiographic success of pulpectomized primary teeth with chronic infection using a mixture of metronidazole, ciprofloxacin, and minocycline (3MIX)-MP as an intracanal medicament before the obturation...

PURPOSE: Patients who receive (chemo)radiotherapy [(C)RT] for head and neck cancer (HNC) experience multiple treatment effects. However, the presence and recovery of treatment toxicities and how these impact on oral intake over time post-treatment are not fully understood. The primary aim of this study was to examine patient perceptions of the toxicities present and which are barriers to oral intake, up to 3 years post (C)RT. The secondary aim was to identify mealtime strategies used to optimise oral intake...

Anterior crossbite is one of the most common forms of malocclusion in sagittal relationship of maxilla and mandible. If not corrected at the earliest, it will cause restriction of normal growth and development of both the jaws. The incidence of anterior crossbite is 4 to 5% in primary dentition. Self-correction may occur at the transient dentition or permanent dentition stage, but treating it should be the first priority. Using either removable or fixed appliances is recommended for the correction, but it depends on the patient cooperation, treatment duration, and parent approval...

Dentinogenesis imperfecta (DI) is a hereditary condition that may affect both primary and permanent dentition and is characterized by abnormal dentin formation. The teeth may be discolored with chipping of enamel and, in untreated cases, the entire dentition may wear off to the gingiva. This may lead to the formation of abscesses, tooth mobility, and early loss of teeth. In the Indian population, DI is found to have an incidence of 0.09%. Treatment of DI should aim to remove infection, if any, from the oral cavity; restore form, function, and esthetics; and protect posterior teeth from wear for maintaining the occlusal vertical dimension...

The main characteristic feature of the pediatric mandible is that of decreased dimension, which leads to compromises in the open reduction and internal fixation (ORIF). In the dental segment, the cervically bulbous short stature primary teeth might act an obstacle during the maxillomandibular fixation conventionally. An increased osteogenic potential of bones favors rapid consolidation and remodeling in the affected region. The mixed dentition of the ugly duckling stage adds more burden while stabilizing the fractured segments...
