In patients with chronic periodontitis, a combination of a single application of PDT (using a 980 nm laser and MB) and LLLT provide additional benefit to SRP in terms of clinical parameters 6 months following the intervention.

Background:The present study aims to evaluate the efficacy of diode laser alone and in combination with desensitizing toothpastes in occluding dentinal tubules (both partially occluded and completely occluded tubules) by scanning electron microscope (SEM).Materials and Methods:Fifty human teeth were extracted, cervical cavities were prepared and etched with 17% ethylenediaminetetraacetic acid, and smear layer was removed to expose the tubules. The teeth were divided into five groups: Group I – Application of NovaMin-formulated toothpaste, Group II – Application of Pro-Argin™-formulated toothpaste, Group III – Application of diode laser in noncontact mode, Group IV – NovaMin-formulated toothpaste followed by laser irradiation, and Group V – Pro-Argin™-formulated toothpaste followed by laser irradiation. After treatment, quantitative analysis of occluded dentinal tubules was done by SEM analysis.Results:The mean values of percentages of total occlusion of dentinal tubules in Groups I, II, III, IV, and V were 92.73% ± 1.38, 90.67% ± 1.86, 96.57% ± 0.64, 97.3% ± 0.68, and 96.9% ± 6.08, respectively. Addition of diode laser (Groups III, IV, and V) yielded a significant occlusion of the dentinal tubules when compared to desensitizing toothpastes alone (Groups I and II).Conclusion:Diode laser (Group III) has shown more efficacy in occluding dentinal tubules when compared with desensitizing toothpastes which was statistically significant (P < 0.05). Among the five groups, NovaMin + diode laser (Group IV) showed the highest percentage of occluded dentinal tubules.

Review ArticleTechniques for maxillary sinus augmentation 1. Lateral window approach/direct sinus lift [15] 2. Transcrestal approach/indirect sinus lift [16] 3. Minimal invasive surgery Background: Present article describes the various treatment modalities available for posterior maxillary rehabilitation. Preservation of the remains and restoration of the missing is needy to maintain the form and function of the stomatognathic system. Loss of a tooth can be common in any of the arches. The rehabilitation of the lost dental and alveolar part in the maxillary arch is more technique sensitive in comparison to the corresponding arch. The inferior quality of bone in comparison to the mandibular arch fixed restorative procedures is quite cumbersome to the practitioner. This article is an attempt to explain the various options that can be opted for the rehabilitation of the edentulous maxillary arch according to the diagnosed condition of the individual.
