Introduction Surface roughness encourages plaque retention and causes mechanical, chemical, and biological irritation to surrounding soft tissues. Hence, a smooth surface of restoration is preferred for optimal plaque control and the health of the periodontium. Aim The aim is to evaluate and compare the surface roughness of porcelain fused to metal and stainless-steel crowns following ultrasonic and hand scaling techniques. Material and methods An in-vitro study was conducted on 30 porcelain fused to metal crowns and 30 stainless-steel crowns. Their surface roughness following instrumentation was evaluated by scanning electron microscope (SEM) and profilometry. Results Evaluation by profilometry indicated that porcelain fused to metal following ultrasonic instrumentation has a statistically more significant surface roughness and indentation as compared to hand scaling with p-values0.05. Conclusion The surface roughness of any restoration may act as a plaque retentive factor which would affect the health of the periodontium. Ultrasonic scaling is capable of creating roughness to a more extent as compared to hand scaling and porcelain fused to the metal type of restorations is more vulnerable to roughness.

Ethnomedicines in the literature compare the therapeutic efficacy of various herbs based on active ingredients of plants and animals. The application of phytomedicines in the field of dentistry is uncommon. The main objective of this article is to access the efficacy of ethnomedicines and newly evolving treatment modalities in reducing post-op complications following dentoalveolar surgeries. Inclusion criteria were selected according to the population, intervention, control, and outcomes (PICO) format. Case reports, case series, retrospective studies, and studies with inappropriate reporting of outcomes were all excluded. An electronic search of English literature in PubMed was performed using the keywords Ethnomedicine, Anti-inflammatory, Analgesics, Therapeutic herbs, Herbal mouthwashes, Third molar surgery. A total of 25 articles were selected, of which three were on herbal mouthwashes and 22 were on anti-inflammatory effect. All the articles were regarding the therapeutic effect of the herbs. The present paper studies various traditionally used therapeutic herbs, their benefits, and shortcomings with their application in dentistry. This study has shown the different herbal alternatives to conventionally used drugs in relation to third molar.
