A normal scalloped gingival line at the cement enamel junction of the teeth forms one of the components of an aesthetic smile. Clinicians handle gingiva in several periodontal procedures and the resulting gingival architecture is not always ideal. In the era of aesthetic-driven dental therapy, it is important that a clinician should be well aware of all the prognostic factors that may affect the final aesthetic outcome of dental treatment. Gingival biotype is one of the important factors which influences indications and outcome of various periodontal, restoratives, surgical, and implant therapy. Thin gingival biotype responds differently than thick gingival biotype. Gingival biotype assessment before various dental-related procedures is mandatory now to achieve a predictable and stable gingival margin position. This review describes the various classifications, methods of assessment, and clinical importance of gingival biotype during dental treatment.

Gingival recession is one of the aesthetic concern for a beautiful smile. In an aesthetically driven era, root coverage requires consideration of all prognostic factors for successful results. This paper reports a case of treatment of Miller’s Class I gingival recession involving multiple teeth. A modified coronally advanced flap procedure was performed. At the postoperative follow-up visits, healing was uneventful. After 9 months, excellent aesthetic result was achieved with complete root coverage. Periodontal health was normal and the patient was satisfied with the result.

Gingival recession is a common mucogingival deformity that brings aesthetic discomfort, hypersensitivity and inability to perform proper oral hygiene. LPF is the widely used technique to cover single recession of Miller Class-I and Class-II when adequate keratinized tissue exists adjacent to the recession. We report a case of 32-year-old female who presented with chief complaints of receding gum and sensitivity in lower front teeth region. Clinical examination revealed Miller’s Class-I vertical recession with 4 mm depth on buccal aspect of left mandibular canine. LPF was planned and operated for the root coverage. After 6 months of therapy, 100% root coverage was achieved with satisfactory healing and aesthetic was comparable to adjacent gingiva.

Background: : Chronic periodontitis is one of the most common form of periodontal diseases which either require non-surgical periodontal therapy or open flap debridement-surgical therapy or both. To date, it is unclear as of how much changes occur after NSPT or OFD and which therapy provides the best outcome in chronic periodontitis having probing pocket depth ≥ 5-7 mm. Aim: The aim of this randomized controlled clinical trial was to evaluate the Probing Pocket Depth and Clinical Attachment Level between NSPT and OFD in chronic periodontitis patients. Materials and Methods: A total of 52 healthy patients with PPD ≥ 5-7 mm were included in the present study. Half of the patients assigned for the NSPT and half in the OFD group. The PPD and CAL were measured at baseline, three and six months. Independent sample t-test was used to compare the change in mean PPD and CAL between NSPT and OFD group at three and six months, respectively. Results: The difference in the mean decrease of PPD between NSPT and OFD group at three and six months were 0.15 mm (P<0.05) and 0.19 mm (P<0.05), respectively. The difference in the mean gain of CAL between NSPT and OFD group at three and six months were 0.03 mm (p>0.05) and 0.12 mm (P<0.05), respectively. Conclusion: Substantial improvement in periodontal status occurred with both the therapies, however, significantly higher decrease in PPD and gain in CAL were seen with surgical therapy.

In this paper, an empirical model was developed for high stress abrasive wear behaviour of unidirectional sisal fibre reinforced epoxy composites under varying operating parameters, for which a number of experiments were carried out to determine the abrasive wear behaviour of the composites. Polysulphide modified epoxy resin was used to make composites having three different sisal fibre concentrations in three different fibre orientations, namely longitudinal, transverse and normal. Abrasive wear of composites depends on operating parameters, such as applied load, grit size, sliding distance and weight percentage of sisal fibre. The abrasive wear data have been analysed using statistical analysis, and empirical relations are proposed.
