Mandibular Alveolar Ridge Split With Simultaneous Implant Placement: A Case Report.

Bone resorption following tooth loss is an obvious, continuous, and unpredictable process, which poses one of the greatest challenges in implant placement. The posterior regions of the jaws show more resorption compared to the anterior regions, with the mandible being affected more. Augmentation of the narrow alveolar ridge has been done using various techniques. The alveolar ridge split technique (ARST) is frequently used for the horizontal augmentation of the narrow ridge. In this case report, a 47-year-old female patient who had partial edentulism on the lower left jaw region associated with a narrow alveolar ridge was treated using the ridge split technique. A piezosurgical unit was used for splitting the ridge, followed by simultaneous implant placement. This alveolar ridge split technique is considered to be more predictable, reliable, and successful as compared to other techniques such as autogenous onlay bone graft and guided bone regeneration.

Nonsurgical treatment of two periapical lesions with calcium hydroxide using two different vehicles.

Calcium hydroxide is used extensively as an intracanal medicament in endodontics for many years. It is used in various clinical situations such as to promote apexification, to repair perforation, to enhance healing of periapical lesions, to control root resorption, and to control exudation in teeth with persistent periapical inflammation. This paper presents a case report in which Ca(OH)2 was used as an intracanal medicament for treatment of periradicular lesions using two different vehicles in two different teeth of same patient.

Evaluation of fracture resistance of roots obturated with resilon and thermoplasticized gutta-percha: An in vitro study.

AIM: To investigate and compare the fracture resistance of resilon and realseal filled root canals with those that were obturated with thermoplasticized gutta-percha and AH-plus endodontic sealer. MATERIALS AND METHODS: Eighty extracted human mandibular single-rooted premolars stored in 10% formalin were used in this study. They were prepared by using a crown-down technique, debrided and irrigated with NaOCl, EDTA, and normal saline and divided into four groups. Group I = Negative control, canals prepared but no obturation was done; Group II = Positive control obturated with dual cure composite resin; Group III = Obturated with thermoplasticized GP and AH-plus; Group IV = Obturated with resilon and realseal. All root specimens were stored for two weeks in 100% humidity to allow for complete setting of the sealer. Each specimen was mounted in acrylic in a polyvinyl ring and tested for fracture resistance with a universal testing machine. The loading fixture of the machine was mounted with its spherical tip aligned with the center of the access opening of each root. A vertical loading force was applied until it fractured the root. The force values were subjected to statistical analysis: Kruskall-Wallis H-test and Mann-Whitney U-test. RESULTS: Group comparison revealed that Group II (positive control) had significantly higher values of resistance to fracture as compared to all the other groups. While Group IV (resilon with realseal) had significantly higher values of resistance to fracture as compared to Group I (negative control). CONCLUSION: On the basis of our findings, it can be concluded that filling the root canals with resilon and realseal increased the in vitro resistance to fracture of single-canal extracted teeth. resilon and realseal demonstrated high fracture-resistance values and could be an alternative to the conventional gutta-percha.

Unusual gingival enlargement: a rare case report.

This is an atypical case report of a 20-year-old male patient who suffered from unusual unilateral, gingival enlargement together with rapidly progressive alveolar bone loss. The enlarged gingiva completely covered his left posterior teeth in both arches. The patient was diagnosed with gingival fibromatosis and aggressive periodontitis based on the clinical, histological, and radiographic findings. The gingival enlargement was treated by conventional gingivectomy under local anaesthesia. The postoperative result was uneventful.

Root End Generation: An Unsung Characteristic Property of MTA-A Case Report.

Management of immature teeth with necrotic pulp and periapical lesion has long presented a challenge. The treatment of choice for such teeth is apexification, which is induction of apical closure to produce more favorable conditions for conventional canal obturation. Traditionally, calcium hydroxide has been used for the apexification of immature permanent teeth, however, Mineral Trioxide Aggregate (MTA) holds significant promise not only as an alternative to multiple treatment visits with calcium hydroxide but also having the potential to induce root end development, eventually forming a completed root apex. This case report presents a successful healing and apexification with the use of calcium hydroxide and MTA. A 5-year follow-up revealed root development with MTA.

Comment on "Evaluation of Manual and Two-Rotary NiTi Retreatment Systems in Removing Gutta-Percha Obturated with Two Root Canal Sealers".

Proper research design, appropriate evaluation and measurement methods, use of correct statistical tests, interpretation, and inference are the essentials without which any scientific research reporting is incomplete and does not serve its proposed purpose. In this communication, some common flaws in research designing, evaluation, analysis, and inference have been explained using a published article as a reference. The purpose of the paper is to help the scientific community recognize the significance of proper research designing and planning in order to achieve the results which are worthwhile.

Comment on "dental prosthetic status and prosthetic need of the institutionalized elderly living in geriatric homes in mangalore: a pilot study".

Public Health Dentistry is a speciality which is targeted towards the larger benefit of community and society. Dental health surveys in specific population groups should be planned adequately and the data should be analyzed in such a way so that it may help in making strategies for the intervention to improve the existing status. This could be only done with the help of proper planning, analysis and interpretation of a sample survey. The present study highlights the research design, statistical and inferential errors in a published work of public health dentistry in order to bring about the common mistakes and errors made. The renewed suggested approach helps in interpreting the results in a better way and makes them objective-oriented.

Comment on "Computed Tomography Evaluation of Craniomandibular Articulation in Class II Division 1 Malocclusion and Class I Normal Occlusion Subjects in North Indian Population".

Clear statement of objective, appropriate location of landmarks and removal of subjective bias in measurement is essential in all kinds of research, especially, orthodontics. The research design should be rationalistic, purposeful, and in accordance with the objectives of the study. In this communication, we highlight the errors in research design, measurement, analysis, and inferences drawn with the help of a published article as the primary source to explain these simple but useful points.
