Mandibular premolar with two roots

This case report illustrates the relatively uncommon anomaly of a mandibular second premolar with two roots branching in a mesiodistal direction.

Lymphangioma of the tongue.

Lymphangiomas are developmental malformations and have a marked predilection for the head and neck region. They are benign proliferation of lymphatic vessels and represents hamartomas of malformed lymphatics. The most common location in the mouth is the dorsum of tongue, followed by lips, buccal mucosa, soft palate, and floor of the mouth. In the tongue, they may present as a localized or a diffused growth which may enlarge to cause macroglossia, impaired speech and difficulty in mastication. These tumors are typically present at birth, but may go unnoticed until after dentition erupts or even after puberty. Presenting here is a case of localized lymphangioma of the tongue in a five year old child and its surgical management.

Comparative evaluation of shear bond strength and nanoleakage of conventional and self-adhering flowable composites to primary teeth dentin

Background: The latest advancement in adhesive dentistry is the development of self adhering flowable composite resin which incorporates the self-etch adhesion technology to eliminate the steps of etching, rinsing, priming and bonding. Few studies have addressed resin bonding to primary teeth. Aim: The aim of this study was to compare the shear bond strength and nanoleakage of conventional and self adhering flowable composites to primary teeth dentin. Settings and Design: This study was conducted in the Department of Pedodontics and Preventive Dentistry, I.T.S Dental College, Hospital and Research Centre, Greater Noida; in association with the Department of Mechanical Engineering, I.T.S Engineering College, Greater Noida; and the Advanced Instrumentation Research Facility (AIRF), Jawaharlal Nehru University, New Delhi. Materials and Methods: Sixty of the ninety primary teeth were evaluated for shear bond strength and thirty for nanoleakage. The samples were divided into three groups; Group I - Dyad Flow (Kerr), Group II - Fusio Liquid Dentin (Pentron Clinical Technologies) and Group III - G-aenial Universal Flo (GC). Shear bond strength was determined using a universal testing machine. Nanoleakage pattern was observed under scanning electron microscope. Results: The shear bond strength of conventional flowable composite was significantly greater than self adhering flowable composite (p<0.05). Nanoleakage scores of both conventional and self adhering flowable composites were comparable. Conclusions: Self adhering flowable composites combine properties of composites and self etch adhesives, eliminating the need for separate bond application that simplifies direct restorative procedure. The evolution of self adhering materials could open new horizons for pediatric dentistry.

Correlation of Streptococcus mutans count in Mother-child Pair of Working and Nonworking Mothers: A Cross-sectional Study.

Purpose To determine the prevalence of Streptococcus mutans (MS) in mother-child pairs and to evaluate the correlation in the levels of salivary MS of working and nonworking mothers with that of their children and their associations with other related factors. Materials and methods A cross-sectional study was carried out among 100 mother-child pairs residing in New Multan Nagar Colony, New Delhi, India. A total of 50 children with their mothers were included in the working group and another 50 were included in the nonworking group. A questionnaire regarding the feeding habits, oral hygiene habits, daily intake of sugars of the children along with their weaning time was carried out. All mothers and children were clinically examined for recording decayed, extracted, and filled teeth (deft)/decayed, missing, and filled teeth (DMFT), and whole unstimulated saliva was collected and cultured for MS in the laboratory. The data were collected and subjected to statistical analysis using chi-square, Spearman’s correlation, and logistic regression analysis. Results The prevalence of salivary MS in the children was 69%. A statistically significant correlation was found between the oral levels of MS in nonworking and working mother-child pairs. Regression analysis showed that those children who feed by bottle for more than 12 months, have daily sweet intake, have sugars in feeding bottle and have higher defts were more likely to have mutans score of 1 or 2. Conclusion The mother, working or nonworking, being the primary care provider is the major source of transmission of MS to their child irrespective of the amount of time spent with them.

Sturge-Weber syndrome: A case report

Sturge-Weber syndrome (SWS), also called as encephalotrigeminal angiomatosis is an uncommon congenital neurological disorder & frequent among the neurocutaneous syndromes specifically with vascular predominance. This disorder is characterized by facial capillary malformation & other neurological condition. The oral manifestations are gingival hemangiomatosis restricting to either side in upper and lower jaw, sometimes bilateral. We report a case of SWS with oral, ocular and neurological features.

Surgical management of multiple supernumerary teeth and an impacted maxillary permanent central incisor.

Hyperdontia is the condition of having supernumerary teeth, or teeth which appear in addition to the regular number of teeth. It is a developmental anomaly and has been argued to arise from multiple aetiologies. The most common site is the maxillary incisor region; but the prevalence of more than three teeth supernumerary tooth is less than 1%. A case of 13 year male patient is reported with a multiple impacted supernumerary tooth in maxillary anterior region hindering the eruption of right permanent central incisor. The supernumerary tooth was treated via surgical approach followed by an interim prosthesis for permanent central incisor which later on erupted in due course of time. Background Supernumerary teeth may be defined as any teeth or tooth substance in excess of the usual configuration of 20 deciduous and 32 permanent teeth. The presence of supernumerary teeth in the premaxillary region often poses unique diagnostic and managerial concerns for the practitioner. Rarely is the surplus number compensated by an absence or deficiency of other teeth. Therefore, the dysfunctional nature of supernumerary teeth and their ability to create a variety of pathological disturbances in the normal eruption and position of adjacent teeth warrants their early detection and prudent management. Approximately 76-86% of cases represent single-tooth hyperdontia, with two supernumerary teeth noted in 12-23% and three or more extra teeth noted in less than 1% of cases. Multiple supernumerary teeth are also associated with many syndromes like cleidocranial dysplasia and Gardner’s syndrome etc. However, it is rare to find multiple supernumeraries in individuals with no other associated disease or syndrome. In such cases, the maxillary anterior region is the common site of occurrence. The exact aetiology is not clearly understood. The supernumerary teeth result from any disturbance in the initiation and proliferation stages of odontogenesis. There are several theories regarding the development of a supernumerary tooth-phylogenetic reversion (atavism) theory, dichotomy of tooth germ theory and hyperactivity of the dental lamina. The latter being the most accepted theory, states that the remnants of dental lamina or palatal offshoots of active dental lamina are induced to develop into an extra tooth bud, which results in the formation of a supernumerary tooth. Genetics is also considered to contribute to the development of supernumerary teeth, as these have been diagnosed in twins, siblings and sequential generations of a family. Classification of supernumerary teeth may be on the basis of position or form. Positional variations include mesiodens, paramolars, distomolars and parapremolars. Variations in form consist of conical types, tuberculate types, supplemental teeth and odontomes. Supernumerary teeth may, therefore, vary from a simple odontome, through a conical or tuberculate tooth to a supplemental tooth which closely resembles a normal tooth. Also, the site and number of supernumeraries can vary greatly. This report presents a case of a non-syndromic male patient with multiple supernumerary teeth and a permanent impacted tooth in the maxillary anterior region.

Bilateral radix entomolaris with primary and permanent mandibular first molars

Dental practitioners should be aware of the morphological dental anomalies like additional roots; their location, incidence and associated unusual root canal morphology. They should also carefully interpret the intraoral radiographs so that such anomalies do not go unnoticed.

Evaluation of the Effect of Different Root Canal Preparation Techniques in Primary Teeth Using CBCT

OBJECTIVES The purpose of this in vitro study was to compare and evaluate the cleaning and shaping efficiency of the rotary Ni-Ti, sonic and conventional file systems for root canal preparation in primary teeth under CBCT. STUDY DESIGN Seventy five maxillary and mandibular first and second primary molars were divided into three groups of 25 teeth each, according to the canal preparation technique: Group I Rotary file system, Group II Sonic file system, Group III Conventional K files. Canals were scanned using an i-CAT CBCT scanner before and after preparation to evaluate their shaping efficiency. Root canal transportation and centering ratio were evaluated at coronal, middle and apical thirds. The cleaning efficiency was evaluated by the extent of India ink removal from the canal walls under stereomicroscope. The collected data was subjected to statistical analysis. RESULTS Nickel-Titanium (Ni-Ti) rotary system caused less canal transportation and had better centering ability. Sonic system showed better shaping at the apex, and wider at coronal end. Conventional K-files removed more dentin at coronal than in middle and apex and efficiently cleaned the root canals. There were no significant difference in cleaning and shaping efficiency between Rotary system, Sonic system & Conventional K file system. CONCLUSION Rotary instrumentations could be considered as an efficient alternative to conventional hand preparation as it respects the original canal anatomy with no aberrations or resulting failures.

Primary molars with extra root canals-a case series

A thorough knowledge of the root canal morphology is essential for the endodontic therapy of primary teeth. Variations in the root canal systems in primary teeth can create a challenge to the practitioners during endodontic treatment. Meticulous cleaning and filling of all the root canals in all its dimensions, helps to eliminate or reduce the microbial load in the canals. The dentists should be aware of such variations and should be motivated to look for them in order to avoid post-operative complications. This article discusses the endodontic management of two primary maxillary second molars and one primary mandibular first molar with additional canals.

Congenitally missing primary mandibular lateral incisors: a case of rare occurrence

We are reporting a rare case of missing teeth in primary dentition. The case reported with the chief complaint of missing teeth in the lower front tooth region. The concern of the parents was missing primary teeth but they were also worried about the permanent successors. Thorough evaluation of the primary dentition visually and permanent dentition radiographically was done. There was missing 72 and 82.Along with these, there were few permanent teeth, that is, lack of initiation of 35 and 45 and 22 was evident. The case was non-syndromic. At present, the case is under follow-up.
