Background: Temporomandibular joint (TMJ) ankylosis or hypomobility involves fusion of the mandibular condyle to the base of the skull. It is a major clinical problem that affects many patients suffering from facial trauma, infection, or systemic disease. The treatment of TMJ ankylosis poses a significant challenge because of technical difficulties and a high incidence of recurrence. Case Report: This report describes a case of a 4-year-old boy with inability to open mouth, diagnosed with unilateral right bony TMJ ankylosis. The surgical approach consisted of gap arthroplasty followed by vigorous physiotherapy. Conclusion: A detailed history, clinical and functional examination, radiographic examination facilitating correct diagnosis followed by immediate surgical intervention, and physiotherapy can help us to restore physical, psychological, and emotional health of the child patient.

Traumatic lesions in primary teeth are frequent in pediatric patients and can cause problems both to the deciduous tooth and permanent successor. The impact strength on deciduous tooth can reach the growing permanent tooth, affecting its morphology, structure and position, or even hampering its proper development. This report describes an aesthetic-functional rehabilitation process in an 8 year 10 month old boy during a multidisciplinary treatment held at the Clinical Center of Dental Trauma in Primary Teeth of the Pediatric Dentistry of Dental College of University of São Paulo, Brazil. The patient presented bilateral posterior cross bite and the permanent left upper central incisor with ectopic eruption and enamel hypoplasy, preceded by avulsion of element 61, occurred when the patient was 1.6 years old. After diagnosis and treatment planning, a quick expansion of jaws was recommended with Hass-type rapid expander and orthodontic leveling with fixed braces. Due to the ectopic eruption, the gingival contour had been altered and hypertrophia was found, compromising aesthetics and avoiding local hygienic procedures. Gingivoplasty was carried out with high-intensity Diode Laser, followed by aesthetic restoration with compound resin. It was concluded that after deciduous teeth traumatism it is important that the patient undergoes clinic and radiographic assistance until the permanent teeth erupt so that an adequate multidisciplinary treatment can be offered to the patient.

Objectives: The objective of this study was to evaluate tooth brushing management and ability of children in relation to age and gender. Materials and Methods: The study population consisted of 45 children, who attended Department of Pedodontics and Preventive Dentistry at V.S Dental College and Hospital Bangalore. Children were divided into three groups according to age: Group I: 3-5 years, Group II: 6-8 years, and Group III: 9-11 years. Each child selected his/her favorite toothbrush and brushed his/her teeth under supervision of one instructor. The grip type during tooth brushing was recorded on a videotape and duration of tooth brushing also was noted. The data were analyzed in relation to the age and gender using the chi-square test. ANOVA was used to find if there is any significant difference between the mean brushing times in the different groups. Results: The results of statistical analysis showed that in all cases P >0.05 for grip preferences and P <0.001 between age groups 3-5 years and 9-11 years with respect to the mean brushing time. Conclusion: The required manual dexterity for tooth brushing was present in younger age groups.

In the last 20 years, two different techniques for bonding fixed retainers have evolved, direct and indirect. Various diameter and alloy of wires are used for this purpose. Indirect method requires an elaborate laboratory procedure for holding the retainer wire on teeth surface for bonding. In the direct method, the retainer wire needs to be prefabricated for accurate fit on the lingual surface of the teeth. These methods have certain shortcomings inherent in them. To overcome these problems, two new techniques have been developed.

Goldenhar syndrome also known as oculo-auriculo-vertebral syndrome was first reported by Dr Maurice Goldenhar in 1952. It is a rare disease entity characterized by craniofacial anomalies such as hypoplasia of the mandible and malar bones, microtia, and vertebral anomalies. The etiology of this disease still remains unclear and occurs as sporadic. This report presents goldenhar syndrome in a 12-year-old male patient.

Tobacco use is one of the leading preventable causes of illness and death. The most powerful predictor of adult smoking is smoking during adolescence. While general and pediatric dentists have a positive attitude regarding tobacco cessation counseling, the same is not extrapolated into practice. Several barriers to counseling in the dental clinic have been identified and research into some of these has been conducted. Evidence-based cessation programs are still in the nascent stage, but this should not hinder dental professionals from rendering these services to the child and adolescent populations. Brief interventions, self-help materials, and nicotine replacement therapy for established nicotine dependence form the mainstay of therapy. The purpose of this paper is to identify the several barriers encountered in providing cessation and discuss the current status of its implementation in the dental clinic.

Alterations in the functions of the facial muscle can establish changes in facial skeleton and in the development of occlusion. The effect of mouth breathing on the facial morphology is probably greatest during the growth period. Removal of nasal obstruction, adenoids, and tonsils have not given beneficial results in the reversion of the habit unless intercepted with various muscle exercises. Hence, this study was conducted to ultrasonographically evaluate the effectiveness of circumoral muscle exercises in the developing dentofacial morphology in adenotonsillectomized children.

This paper presents a case of dentin dysplasia, a rarely reported disorder that is also associated with pyogenic granuloma in a 12-year-old girl. The case presented as excessively mobile teeth that appeared radiographically as rootless teeth and also as a soft tissue lesion in the right maxillary anterior region.

The present in vitro study was carried out on 60 extracted human maxillary and mandibular, first and second primary molars, which were distributed equally into four groups to determine the prevalence, size, shape, location, and number of accessory canals in the pulpal floor of primary molars. The specimens were observed under scanning electron microscope. Out of 60, 34 teeth showed accessory canals with 97 patent canals. It was observed that maxillary molars showed a greater number of accessory canals when compared to mandibular molars, but mandibular molars showed a greater dimension in the size of the accessory canals. Round and oval accessory canals were seen, with round being more predominant.

The aim of the report was to highlight the rarity of occurrence of bilaterally fused mandibular primary lateral incisors and canines by virtue of the number of such cases reported in literature; to identify congenital absence of successor teeth;and to evaluate their pulpal morphologies to understand the type of fusion. Clinical observation along with an orthopantomograph and periapical radiographs were used to arrive at a diagnosis. The pulpal morphologies varied in each of the fused teeth although both were fusions of the Complete type. There was congenital absence of the permanent mandibular lateral incisors, bilaterally. It was a case of bilateral fusion of mandibular primary lateral incisors and canines of the Complete type with congenitally absent mandibular permanent lateral incisors. Only 13 such cases have been previously reported in literature.

Purpose: The purpose of this study was to compare accuracy and reproducibility of visual inspection (VI), bitewing (BW) radiography, and laser fluorescence (LF, DIANOdent) methods in the diagnosis of occlusal caries. Materials and Methods: The study was done on 80 extracted permanent premolars that seem to be intact or with primary caries in fissures. Three trained dentist examined the teeth in four stages: VI, BW radiography, LF, and histologic examination. Sensitivity, specificity, positive and negative predictive values, and accuracy of all methods were calculated and compared. For the LF method, using ROC curve and counterpart points on it, we determined upper and lower limits and calculated the parameters. Results: The estimated accuracy was 58.9% for VI and 45.1% for BW radiography methods. Kappa coefficient for interexaminer reproducibility was 57% and 34.1% in VI and BW radiography, respectively. Inter- and intraexaminer reproducibility coefficients of LF methods were 78.4% and 83.6%, respectively. The mean intraexaminer reproducibility coefficient in the VI method was 61.2%. Conclusion: Although accuracy and reproducibility of the LF method were higher than those of the VI and BW radiography, it is better to use this method together with other methods to reduce diagnostic faults.
