Cementoblastoma is a benign lesion of the odontogenic ectomesenchymal origin. It rarely occurs in primary dentition. This report describes a case of a cementoblastoma relating to the right mandibular second primary molar in a 7-year-old girl. Her panoramic radiograph revealed a well-defined radiopaque lesion with a radiolucent border extending from the distal surface of the mandibular right first primary molar to the distal surface of mandibular second primary molar. The tumor was attached to the mesial root of primary second molar and was excised along with the teeth involved and sent for histopathological evaluation, which showed irregular trabeculae of mineralized tissue interspersed with fibrovascular connective tissue, trabeculae of mineralized tissue with prominent reversal lines, and peripheral rimming of the mineralized tissue with blast cells. On a six-month follow-up, there has been no recurrence of the lesion.
Delayed eruption of maxillary permanent central incisors in a child poses a distressing esthetic quandary to parents, by virtue of its location in the dental architecture. Well-aligned anterior teeth add confidence to smile and have enhanced self-esteem, which is critical even in early life. Impaction of the maxillary central incisors compared to third molars or the canines is less reported; bilateral supplemental maxillary central incisors related to impacted permanent maxillary central incisors are rare and one of the supplemental central incisors showing unusual talon is still infrequent. A case of impacted maxillary permanent central incisors related to supplemental maxillary central incisors, with one of them showing an unusual talon cusp, is presented.
Facial trauma resulting in tooth avulsion results in problems of physical and emotional nature for the patient and a challenge for the dentist. Avulsion accounts for 0.5–16% of traumatic injuries in the permanent dentition that can occur at any age and is most common in the young permanent dentition. As an emergency procedure, it is advisable to replant a traumatically avulsed tooth, but unfortunately long-term success is rather low. After unsuccessful replantation and subsequent extraction, it is prudent to replace the lost tooth to avoid aesthetic, masticatory, and psychological difficulties and also to prevent arch length discrepancy with various alternatives are available for the same. We presented a method for management of one of the two replanted teeth that showed failure, using the natural crown as pontic in a fixed semi-permanent bridge until a more definitive prosthesis can be fabricated at a later age for better patient compliance.
Traumatic injuries to the young permanent teeth lead to devitalization of the pulp with concomitant arrest in further development of the immature root of the involved tooth. Hermetic seal of the root canal system during obturation is not possible in such cases, due to the lack of an apical constriction. The traditional management technique in such cases has been apexification involving induction of a calcific barrier at the apex using calcium hydroxide, which in turn facilitates obturation of the root canal. However this becomes complicated when there is persistent infection leading to periapical changes. This case report describes the use of mineral trioxide aggregate (MTA) for management of a periapically compromised immature tooth.
Aims:To evaluate the effectiveness of different disinfectant agents in decontaminating the toothbrushes, and to educate the children, parents and the community on the decontamination of toothbrushes.Materials and Methods:Fifty healthy male children in the age range of 8–11 years were enrolled. They were divided into five groups of 10 each and provided with toothbrushes and disinfectants. Instructions were given to the children and the toothbrushes were collected after brushing and cultured for the growth of microorganisms. The efficacy of Hexidine®, 3.0% hydrogen peroxide and Listerine® and Dettol® were evaluated. Chi-square test was used for statistical analysis.Results:Hexidine, 3.0% hydrogen peroxide and Listerine showed 100% efficacy, whereas Dettol showed 40% effectiveness in decontaminating the toothbrushes. Water as a control showed the least effectiveness in cleaning the toothbrushes.Conclusions:The study concluded that 3.0% hydrogen peroxide is the most economical and effective disinfectant when compared with the other disinfectants.
Early Childhood Caries (ECC) is a severe debilitating disease affecting the primary dentition of young children in both developing and industrialized countries. Historically, the management of ECC has a global scenario showing operative management of the disease. The contemporary method of preventing the carious process mainly focuses on dietary factors, host factors and removal of plaque biofilm. Enamel demineralization is caused by acidogenic and aciduric bacteria. Colonization of microorganisms in the mouth of children can occur via horizontal or vertical transmission or both. The bacteria present in dental plaque metabolize sugars and starches to produce acids, which lowers the pH in the mouth and promotes loss of minerals from the tooth surface. Sucrose is the most common sugar and when metabolized, produces dextrans which promote superior bacterial adhesion to teeth. Visible plaque on the labial surfaces of the maxillary incisors were strongly associated with the caries development. Saliva buffers plaque acids, aids in oral clearance and acts as a reservoir for minerals to assist in the mineralization of enamel. Most studies have put forward a correlation between bed time use of bottles with sweetened contents especially lactose. One of the factors included by Newbrun in factors causing dental caries is time. The CPP-ACP complex, an effective remineralizing complex preventing the acidic environment reduce incidence of caries. Conventional probiotics comprised of lactobacilli and bifidobacterium which were mainly of intestinal origin; the contemporary probiotic research has brought forward that oral diseases like dental caries, periodontal problems and candida infections have direct link with oral microbial disequilibria. A promising new approach towards primary prevention of the disease is to target the infectious component of Early Childhood Caries by preventing or delaying acquisition of Streptococcus mutans at an early age.
A bstract Background Teeth are hard mineralized anatomical components of the dentofacial skeleton that are developed during the gestation period by odontogenesis. This dental development comprises five stages viz. initiation, proliferation, histodifferentiation, morphodifferentiation, and apposition. Excitation to the dental organ during morphodifferentiation is responsible for the formation of a talon cusp, which manifests as a cusp-like structure of hard tissue projecting from the cingulum to a varying measurable length toward the incisal edge of maxillary and mandibular anterior teeth. Various literature has reported that it comprises enamel, dentine, and an inconsistent amount of pulp tissue. Old literature suggests its occurrence in primary and permanent teeth and mostly on the palatal aspect of teeth as one cusp; therefore, known as a talon cusp (eagle's talon). Case description An exceptional case of three cusped structures projecting from the palatal side of a maxillary central incisor is thus reported. The rare occurrence of an atypical talon cusp with three well-defined mamelon-like cusps on the palatal surface of the permanent maxillary central incisor is coined as ternion cusp, meaning ”three” by authors. Its occurrence is repercussed as attrition of the teeth in the opposite arch. Selective or retruded contact position (RCP) was done, followed by topical fluoride application was rendered. Conclusion Managing and treating these exceptional cusps depends upon their size, present complications, and patient compliance. How to cite this article Sharma V, Mohapatra A, Bagchi A.
