Children who have severely destructive anterior primary dentition, as in nursing-bottle caries, in trauma, in rampant caries and in developmental defects, present the dentist with one of the most perplexing situations in dentistry. Especially, children with managed behavor difficultly is very severly situations. This paper reported a new technique for the utilization of resin post and strip crown to indirect methods on severely destructive primary anterior teeth. We name it "indirect short resin post crown" in this paper. Indirect technique be considered to be a simple, a retentive, intensive, color-stable and esthetic restoration.

Obstructive Sleep Apnea(OSA) is a form of sleep disordered breathing(SDB) characterized by the occurrence of episodes of complete or partial upper airway obstruction during sleep that is often quantified as the apnea-hyponea index(AHI). It is increasingly being recognized that OSA is a public health hazard and there is increasing evidence that it is associated with an increase in morbidity. Early recognition and diagnosis of this condition may lead to earlier treatments (eg, CPAP, Oral appliances) with reduction of the risk of metabolic disease, cardiovascular diseases, such as hypertension, ischemic heart disease, arrhythmias and pulmonary hypertension.

A wide variety of benign and malignant lesions and other diseases can develop on oral mucosa. Oral mucosal lesions can also be associated with an underlying systemic disease, so their correct diagnosis, which may even share similar clinical and demographic features, is always a challenge for a dentist. Common oral mucosal lesions include candidiasis, herpes viral infection, leukoplakia, recurrent aphthous stomatitis, pemphigus, lichen planus and benign migratory glossitis. The differential diagnosis of these lesions are based on a thorough review of the patient's past medical and dental history and a complete oral examination. The knowledge of clinical features such as size, location, morphology, color, and pain is helpful in establishing a diagnosis. In addition, diagnostic tests, including microbiologic and laboratory tests and biopsies are usually required for establishing a proper diagnosis.

Cleidocranial dysplasia (CCD), which is accepted as an autosomal disorder, is a generalized disorder of bone with severe dental abnormalities. Among the most characteristic anomalies seen are hypoplasia of clavicles or aplasia of clavicles, permanant non-ossification of cranial sutures & fontanels, delayed eruption of the permanant dentition & the presence of unerupted supernumerary teeth. CCD may first be noted by dentist because of many dental problems, so we should diagnose the disorder earlier & understand the development of dentition in CCD to ensure timely intervention with proper periodic dental X-ray.

This article reviewed theological background and historicak development in dental caries management by risk assessment. Dental caries prevention and treatment according to CAMBRA model is patient-centered, risk-based, evidence-based practice. Team approach is necessary and clinician need to integrate science, practice and product. Dental hygienist take a important role in implementing CAMBRA. CAMBRA model could be incorporated into dental and dental hygiene education. Dentist and dental hygienist able to provide scientific and ethical care managing dental caries by risk assessment.

The purpose of the pulp treatment is to make the function of the primary molar in the oral cavity possible for as long as possible until the exfoliation of the tooth or the development of the occlusion is as long as possible. The pulpectomy is a relatively common procedure for the pediatric dentist in the clinic with dental care of the children nowadays. Primary molar is morphologically more susceptible to dental caries than permanent tooth, and the dental pulp treatment is frequently performed. Furthermore, unlike permanent teeth, the root canal has a large degree of curvature and morphological diversity and complexity, careful consideration is needed. Therefore, it is very important to comprehensively understand the morphological characteristics and diversity of the root and root canals for the successful pulp treatment of the primary molars.

Osteonecrosis of the jaw (ONJ) is a well-known pathological condition in oncology derived from the use of bisphosphonates (BPs) and denosumab. Many molecular and immunological targets have been introduced for daily use in cancer treatment in recent years; consequently, new cases of ONJ have been reported in association with these drugs, especially if administered with BPs and denosumab. When the drugs are administered alone, ONJ is rarely seen. The objective of our study was to analyze the recent literature relative to the association of ONJ with these new drugs highlighting the pathogenic, clinical and therapeutic aspects. The close collaboration between maxillofacial surgeon, oncologist, dentist, and dental hygienist remains the most important aspect for the prevention, prompt recognition, and treatment of this pathology.

Dental caries is one of the most popular oral disease. The aim of automatic dental cavity detection system is helping dentist to make accurate diagnosis. It is very important to separate cavity from the teeth in the detection system. In this paper, We compared two active contour algorithms, Snake and DRLSE(Distance Regularized Level Set Evolution). To improve performance, image is selected ROI(region of interest), then applied bilateral filter, Canny edge. In order to evaluate the algorithms, we applied to 7 tooth phantoms from incisor to molar. Each teeth contains two cavities of different shape. As a result, Snake is faster than DRLSE, but Snake has limitation to compute topology of objects. DRLSE is slower but those of performance is better.

Oral appliances therapy is becoming increasingly recognized as a successful treatment for snoring and obstructive sleep apnea(OSA). Compared with continuous positive airway pressure(CPAP), the gold standard therapy for OSA, oral appliance therapy are less efficacious for severe OSA but are more acceptable and tolerable for patients, which in turn, may lead to a comparable level of therapeutic effectiveness. Nevertheless, the various side effects of oral appliance therapy, such as, increased salivation or dryness, pain or discomfort in the teeth or gums, occlusal discomfort in the morning, temporomandibular disorders, dental and occlusal changes may cause discontinuation of treatment or changes in treatment plan. Therefore, oral appliance therapy should be provided by a qualified dentist who can evaluate oral tissues, occlusion, and temporomandibular joints, and prevent and manage the possible side effects.

Sleep-disordered breathing (SDB) is defined as a disturbed breathing during sleep caused by repetitive upper airway collapse. Complete collapse causes a cessation of breathing, known as obstructive sleep apnea (OSA) and snoring can arise from partial collapse. Undiagnosed and untreated OSA means recurrent intermittent hypoxemia and leads to a variety of cardiovascular disorders, disturbed neurocognition, and excessive daytime sleepiness. Various behavioral modalities have been suggested for treating snoring and sleep apnea including changing the sleep position, avoiding alcohol, and weight loss. Until now continuous positive airway pressure (CPAP) therapy is one of effective treatment for patients with OSA, but its discomfort causes less tolerance and compliance. Therefore, clinical effectiveness and convenience for oral appliance have emerged and the role of dentists has become more important in the management of OSA.
