Introduction: Third molar impaction surgery is the mainstay of oral and maxillofacial surgery practice. Impaction of tooth is a condition in which a tooth fails to erupt to the normal functional position beyond the chronological age, due to lack of space or physical barrier. The removal of impacted lower third molar may require extensive bone removal leading to post operative complications like pain, edema, trismus, dry socket, hemorrhage etc. Aim: The primary aim of this study was to compare the efficacy of piezosurgery over conventional osteotomy on post operative sequelae of third molar impaction surgery. Materials and methodology: Traditionally rotary instruments like burs are used for osteotomy procedures.A study was done on 120 patients and post operative sequelae were compared for conventional osteotomy and piezosurgery. Results: The results showed lesser post operative edema,trismusetc in the piezosurgery group which were statistically significant. Discussion: Piezosurgery has therefore become a promising alternative to traditional methods of osteotomy.

Assessment of the Awareness, Knowledge, and Attitude towards Gingival Depigmentation among Dental Patients and Analysis of their Pigmentation Patterns

[Year:2021] [Month:July-December] [Volume:10] [Number:2] [Pages:4] [Pages No:54 - 57]

Keywords: Depigmentation, Free gingival unit graft, Gingiva, Pigmentation

   DOI: 10.5005/jp-journals-10029-1232  |  Open Access |  How to cite  | 


Background: The color of gingiva is an utmost esthetic concern among individuals today. In light of this, depigmentation procedures have turned up as the cornerstone of periodontal treatment. This survey mainly aimed to gain insights into the awareness, knowledge, and attitude toward gingival depigmentation among patients visiting the dental hospital in Mangaluru. To this end, we also aimed to analyze the gingival pigmentation patterns and propose a classification for the same. Materials and methods: A survey was conducted among 300 patients attending the department of periodontics. A structured questionnaire was used to obtain information on awareness, knowledge, and attitude toward gingival depigmentation, followed by a clinical examination to assess the smile line and pattern of gingival pigmentation. Results: The data obtained suggest that more than half of the respondents were aware (54.3%) and were concerned (55.3%) about their pigmented gums. However, the majority of the patients (70%) were not aware of the depigmentation procedures. Among the patients who were aware of depigmentation procedures (30%), most of them knew about the laser procedure (60%). Results also revealed low knowledge of reappearance (14%) of the pigmentation after the procedure. Based on clinical examination, patients with class II and class III smile lines were more concerned about their gingival pigmentation. According to the proposed classification of a pattern of gingival pigmentation majority of patients had grade II (A) and grade II (B) types. Conclusion: Although most of the patients were aware of their gingival pigmentation, not many individuals have adequate knowledge of depigmentation procedures. Therefore, significant educational interventions are required to increase awareness among the general population.

The Shear Strength of Orthodontic Attachments Made from Different Composites and Glued in Enamel Conditioned by Two Different Techniques

[Year:2021] [Month:July-December] [Volume:10] [Number:2] [Pages:5] [Pages No:58 - 62]

Keywords: Clear aligner, Orthodontics attachments, Shear strength

   DOI: 10.5005/jp-journals-10029-1233  |  Open Access |  How to cite  | 


Background: The use of removable thermoplastic appliances has become an alternative to the use of conventional fixed appliances through gradual, sequential, and consecutive dental repositioning. Aligners have become a reality. Objective: To evaluate the shear strength of orthodontic attachments made from different composites and affixed to enamel treated with two different conditioning techniques. Materials and methods: A total of 150 bovine incisors were randomly divided into 10 groups (n = 15). In groups I, III, V, VII, and IX, the tooth enamel was etched with 37% phosphoric acid, and then an adhesive was applied. In groups II, IV, VI, VIII, and X, enamel etching was performed with the self-etching agent Transbond Plus Self-Etching Primer (TPSEP). The composites used were Filtek Bulk Fill Flowable (groups I and II), Filtek One Bulk Fill (groups III and IV), Filtek Z350 XT (groups V and VI), Filtek Z250 XT (groups VII and VIII), and Filtek Z100 (groups IX and X). The attachments were molded in a silicone matrix adapted to the buccal area of the teeth, and then light-curing was performed. The samples were stored in distilled water for 24 hours. Subsequently, shear strength tests were performed using a universal mechanical testing machine. The results were analyzed using analysis of variance (ANOVA) and Kruskal–Wallis test and Student's t-test (p = 0.05). Results: There were no significant differences (p = 0.230) among most of the adhesive systems for bonding orthodontic attachments. However, group VII differed from groups II, III, VI, and X (p < 0.05). Conclusion: The Filtek Z250 XT composite on teeth etched with 37% phosphoric acid produced the strongest bond. The bonding was weakest with the Filtek One Bulk Fill composite on teeth etched with 37% phosphoric acid. Clinical significance: With the popularization of aligners, it is necessary to test the materials involved in this treatment modality. Knowing the best material for making the attachments provides a more predictive treatment.

The Efficacy of Photobiomodulation in Wound healing following Gingivectomy: A systematic Review of clinical Studies

[Year:2021] [Month:July-December] [Volume:10] [Number:2] [Pages:8] [Pages No:63 - 70]

Keywords: Gingivectomy, Lasers, Photobiomodulation, Wound healing

   DOI: 10.5005/jp-journals-10029-1235  |  Open Access |  How to cite  | 


Background: There is a controversy regarding the efficacy of photobiomodulation (PBM) in soft tissue healing following gingival procedures. The aim of the current study was to systematically review the efficacy of PBM in wound healing following a gingivectomy. The addressed focus question was, “Is PBM effective in wound healing following gingivectomy?” Indexed databases [Public/Publisher MEDLINE (PubMed), Excerpta Medica dataBASE (EMBASE), Web of Science, and Cochrane] were searched up to December 2020. The risk of bias (RoB) was assessed using Joanna Briggs critical appraisal tool for randomized control trials (RCTs) and case-control studies. Methods: A total of eight studies, six RCTs and two case-control studies, were included in the present review. Seven studies with varying results indicated that PBM application following gingivectomy could enhance wound healing as early as 7 days and help in the reduction of postoperative pain. Wound healing was assessed using either Landry index (two studies), contour, and color of gingiva postsurgically (two studies), or visual analog scale (VAS) scores (three studies) and plaque disclosing solution to measure keratinization in one study. Conclusion: The efficacy of PBM in wound healing following gingivectomy is debatable as the heterogeneity associated with the included studies was high, but overall, the review supports PBM as an adjunctive tool for the promotion of wound healing following gingivectomy. The overall RoB was low in the included studies, further power-adjusted and well-designed RCTs with long-term follow-up are needed.

Restoring Anterior Esthetics with Flapless Implant: A Case Report

[Year:2021] [Month:July-December] [Volume:10] [Number:2] [Pages:3] [Pages No:71 - 73]

Keywords: Anterior esthetics, Anterior restoration, Cemented crown, Flapless surgery, Missing anterior, Single tooth implant

   DOI: 10.5005/jp-journals-10029-1231  |  Open Access |  How to cite  | 


Background: A congenital abnormality or trauma is the most prevalent cause of tooth loss in the anterior area. A patient with a history of single tooth loss, especially in the anterior region, faces practical and cosmetic challenges. When it comes to replacing a lost canine, there are a variety of alternatives, among which implant dentistry should be the first option. Method: The current case report highlights the replacement of a lost maxillary right canine using dental implants by punch technique. Conclusion: Flapless implant technique improves the patient's function and esthetics and hence can be used to achieve a favorable clinical outcome in patients.
