A fundamental objective of an aesthetic treatment is the patient's satisfaction and that the outcome of the treatment should meet the patient's expectation of enhancing his/her facial aesthetics and smile. A patient constantly doubting the end result of the treatment, which is an irreversible procedure, can be motivated and educated through Digital Smile Designing (DSD) technique. DSD is a technical tool which is used to design and modify the smile of patients digitally and help them to visualize it beforehand by creating and presenting a digital mockup of their new smile design before the treatment physically starts. It helps in visual communication and involvement of the patients in their own smile design process, thus ensuring predictable treatment outcome and increasing case acceptance. This article reviews the aspects of digital smile designing in aesthetic dental practice pertaining to its use, advantages, limitations and future prospects.

Dental plaque is the primary etiologic factor for the periodontal diseases. Although pathogenic bacteria in dental plaque are necessary for the incidence of periodontal disease, but a susceptible host is as important. The susceptibility of the host can be modified by various systemic factors with hormones level being one. The periodontium shows an exaggerated inflammatory response to plaque modified by female sex hormone during puberty, pregnancy, in women taking oral contraceptives and at the postmenopausal stage. This paper presents such few cases where periodontium is influenced by variation in sex steroid hormones of female during different phases of their life time and to discuss how much a same hormone at different age and stage shows an exaggerated gingival response to plaque.

Healthy teeth and gums make a person feel confident and fit. As people go about their daily routines and with different eating and drinking habits, the tooth enamel turns yellowish or gets stained. Polishing traditionally has been associated with the prophylaxis procedure in most dental practices, which patients know and expect. However, with overzealous use of polishing procedure, there is wearing of the superficial tooth structure. This would lead to more accumulation of local deposits. Also, it takes a long time for the formation of the fluoride-rich layer of the tooth again. Hence, now-a-days, polishing is not advised as a part of routine oral prophylaxis procedure but is done selectively based on the patients’ need. The article here, gives an insight on the different aspects of the polishing process along with the different methods and agents used for the same.

Historically, surgical techniques were governed by specific incisions and surgical designs. With the advent of anesthesia, the complicated cases were managed but at the cost of the tissues leading to morbidities of various degrees. The innovations and the advances in the surgical techniques led to the ideology that surgeries could be done with minimal tissue manipulation and sacrifice. Thus the concept of "minimally invasive dentistry" was introduced with the primary goal to achieve satisfactory therapeutic results with minimal trauma during the process. In context to the management of periodontitis, this modality includes use of conservative incisions which preserves as much soft tissue as possible, avoiding continuous incisions and vertical incisions, use of magnification etc. The ultimate goal of any treatment modality is the resolution of the disease and regeneration if possible with minimal postoperative pain and morbidity. Minimal invasive periodontal therapy involves treatment options which cure the disease with reduced postoperative pain, improved healing and better patient acceptance. This paper covers the advent of minimal invasive periodontal therapy modalities both surgical and non-surgical along with the literature review.

Background: Successful management of patients reporting with extreme sensitivity in second molar after surgical extraction of deeply impacted mandibular third molar poses a big challenge to oral surgeons and periodontists worldwide. A variety of grafts, barrier membranes, and guided tissue regeneration techniques have been used postsurgically for soft- and hard-tissue formation. In the current study, platelet-rich fibrin (PRF), a second-generation platelet aggregate, was assessed for its effectiveness in promoting hard- and soft-tissue healing. Objective: The aim of the study was to evaluate the efficacy of PRF in hard- and soft-tissue healing after extraction of mandibular third molar. Materials and Methods: Bilateral surgical disimpaction of mandibular third molar was done on 25 patients. In every patient, randomly allocated test side received PRF and the other side acted as control. Pain, edema, tenderness, sensitivity, Sulcus Bleeding Index (SBI), Plaque Index, clinical attachment level (CAL), probing depth, and bone height were measured at different intervals for a maximum period of 6 months. Results: There was a statistically significant improvement in patients' signs and symptoms of pain, tenderness, edema, and sensitivity with the use of PRF. A statistically significant improvement was seen in SBI, Plaque Index, and probing depths, while CALs and bone height were not influenced by PRF use. Conclusion: PRF is a very viable and useful biomaterial for soft-tissue healing and relieving patient symptoms, however, it does not help in hard-tissue healing with respect to cortical bone.

Background:Chronic periodontitis in lower anterior teeth results in rapidly progressive gingival recession (GR), loss of alveolar bone, decreased vestibular depth (VD) with consequential tooth mobility, and tooth loss. Treatment option for such cases in this esthetically important area of the oral cavity includes extraction followed by implants for which sufficient bone height and mucogingival complex are a prerequisite. Henceforth, an attempt was made to prolong the life of lower anterior teeth and postpone the need for implants by the treatment of chronic periodontitis with periodontal flap surgery followed by vestibular deepening in single surgical procedure.Materials and Methods:In this clinical, prospective study, conventional periodontal flap surgery was done on 74 sites in lower anterior teeth in 16 patients with attachment loss >5 mm due to chronic periodontitis. Vestibular deepening with diode laser at (wavelength - 810 nm, output power: 0.5–7 W, continuous wave, contact mode) was done after suturing the flap. All the clinical parameters: GR, pocket depth (PD), clinical attachment loss (CAL), width of keratinized gingiva, width of attached gingiva, and VD were assessed preoperatively after Phase I therapy and 6 months postoperatively.Results:At all the 74 sites, there was highly significant gain in attached gingiva, keratinized gingiva, and VD (P ≤ 0.001). Highly significant reduction in PD (P ≤ 00.001), significant reduction in attachment loss (P ≤ 0.01) but no significant reduction in GR (P = 0.897) was observed.Conclusions:The combination of periodontal flap surgery with vestibular deepening with diode laser may be a suitable cost-effective treatment option to prolong the life of periodontally involved lower anterior teeth. The surgical technique can postpone the need for extraction of teeth along with all the intangible benefits of periodontal therapy.

AIMTo test the reliability of the Sawai’s classification for dental cervical abrasions.METHODSIntraoral photographs of 70 teeth from 23 patients with tooth abrasions were taken by the first examiner MS. The teeth were marked and the photos were maintained in a soft copy sequentially. Two other examiners FA and SC were trained in the use of the classification and any clarifications needed were provided at the beginning of the study. Each examiner was then given the soft copy of the complied photographs and was asked to classify the dental cervical abrasion according to their understanding of the Sawai’s classification. They were given sheets to write their responses for every marked tooth. All the examiners were blinded to each other’s observations which were then tested for inter-rater agreement among the three examiners.RESULTSThe 70 teeth with tooth abrasions from 23 patients were examined by 3 investigators (MS, FA and SC) to test the reliability of the Sawai’s classification system for tooth abrasion. Each examiner marked their responses in separate sheets which were blinded to each other. The kappa statistics were performed for inter-rater agreement among the three examiners. The level of agreement was evaluated according to the six-level nomenclature given by Landis and Koch. ICC and 95%CI between two examiners, i.e., the inter-rater agreement among 1st examiner (MS) and 2nd examiner (FA) was 0.89. The inter-rater agreement among 1st examiner (MS) and 3rd examiner (SC) was 0.89. And the inter-rater agreement among 2nd examiner (FA) and 3rd examiner (SC) was 0.83. All the three comparisons show an almost perfect agreement between them.CONCLUSIONThere is an almost perfect agreement between multiple observers for classifying dental cervical abrasions using Sawai’s classification. Hence, this classification is reliable.
