  ABSTRACT: Supernumerary permanent teeth in the mandibular incisor area are rare, and there are very few reported cases of the supernumerary teeth in the mandibular incisor area leading to impaction of incisors. A south Indian boy aged 14 presented with 3 supernumerary teeth in the mandibular right permanent incisor area resulting in impacted permanent central and lateral incisors.

  ABSTRACT: 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.

  Article: Efficacy of various disinfectants on microbially contaminated toothbrushes due to brushing.

  ABSTRACT: 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. 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. 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. The study concluded that 3.0% hydrogen peroxide is the most economical and effective disinfectant when compared with the other disinfectants.

• Article: Microleakage evaluation using acetate peel technique.

  Abinash Mohapatra, N Sivakumar
  [show abstract] [hide abstract]
  ABSTRACT: To evaluate and measure the interfacial space or the restoration cavity integrity for probable microleakage using acetate film; acetate peel technique under different magnifications. Premolar tooth was obtained and standardized class V restoration with Z-350 done both buccally and lingually. The tooth was hemisectioned buccolingually and embedded in epoxy resin, polished, acid etched, washed and dried. The sectioned sample was flooded with acetone and a pre-cut acetate film placed over it. As the acetone evaporated, the film took the shape of the micro relief produced by etching and dried in 10-15 mins. It was pulled off the tooth surface and mounted between two glass slides for examination under research microscope with different magnifications. This enabled us to measure the interfacial space that might lead to leakage of restoration and also could detect the intricate details of tooth. The acetate peel technique is an efficient way to study the interfacial space/restoration-cavity marginal integrity at a higher magnification and was a fast and reliable tool for assessing the microleakage of a restorative material.

  Article: Atypical presentation of bilateral supplemental maxillary central incisors with unusual talon cusp.

  Sivakumar Nuvvula, Chaitanya Pavuluri, Abinash Mohapatra, Svsg Nirmala
  [show abstract] [hide abstract]
  ABSTRACT: 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.

  Article: Management of immature teeth with apical infections using mineral trioxide aggregate.

  Sivakumar Nuvvula, Tejas H Melkote, Abinash Mohapatra, Svsg Nirmala
  [show abstract] [hide abstract]
  ABSTRACT: 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.
