The availability of different wavelengths of lasers has created a surgical panacea in the last decade and laser technology has become the standard of care for many oral and maxillofacial surgical procedures. In this article, based on literature search, we have reviewed the usage of laser in maxillofacial surgery based on the current evidence available on laser-assisted maxillofacial surgery, in PubMed database.

Background: Shade selection is an essential system to give patients an aesthetics renovation that correspondently merges to the patient's current dentition. Moreover, natural teeth are acknowledged to have various shades in their surfaces. Objective: The aim of the study was to evaluate the awareness of knowledge, attitude and practice about the complications in shade selection and to utilize for improving the quality of training being imparted in the dental school and general practitioners. Methods and Material: Participants were divided into six Groups: operative dentist and endodontist, 3rd Year students, 4th Year students, 5th Year students, Intern and VI-General practitioners; 20 Questionnaire survey forms were distributed to fill among all the groups. Results: The results that the highest proportion was 41% for skill factor, knowledge was the second with 26%. Whilst, individual observer was 13.5% and 12.6% for the factor talent. 4.5% for (All) the factors. The lowest proportion was for more than two answers. Conclusion and Recommendation:The need of flourishing of cosmetic dentistry required to keep with up-todate information considering all conceivable factors which influence shade selection.

Introduction: The study is aimed to compare the clinical outcome of immediate and delayed loaded single tooth implants in replacement of mandibular posterior tooth in consideration with implant stability quotient, bleeding on probing, probing depth, implant mobility, marginal bone loss and peri-implant radiolucency. Materials and Methods: The study consisted of 20 patients who were divided into two groups and compared: Group A is an immediately loaded group with ten patients who received implants in the mandibular posterior tooth region along with abutment on the same day and acrylic crown placed within 48 h and the second group is a conventionally loaded group of ten patients who received the implant in the mandibular posterior tooth region in which the cover screw was placed and conventionally loaded after 3 months. Implant stability quotient, implant mobility, bone loss and peri-implantitis were assessed at 1st and 6th months after loading. All patients were evaluated for the parameters at 1st, 3rd and 6th months after loading in both the groups. Results: Probing depths obtained for all twenty patients after 1 and 6 months of loading were within the normal range (1–3 mm). In Group A, the mean probing depth after 1-month loading was 1.8 mm with a standard deviation (SD) of 0.63 and after 6 months of loading 1.2 mm with SD 0.42. In Group B, the mean of the probing depth after 1 month of loading is 1.8 mm with SD 0.42 and remained the same post loading after 6 months. Marginal bone loss was measured mesially and distally after 1 month and 6 months in both the groups. The standard intraoral periapical radiograph was used to evaluate peri-implant radiolucency. No patient showed peri-implantitis for 6-month follow-up after loading of implants. Conclusion: Immediate loading of an implant in a single mandibular posterior tooth can be an effective treatment modality and a promising alternative to delayed loading.
