Introduction: Several techniques and methods have been proposed to estimate the anterior teeth dimensions in edentulous patients. However, this procedure remains challenging especially when preextraction records are not available. Therefore, the purpose of this study is to evaluate some of the existing extraoral and intraoral methods for estimation of anterior tooth dimensions and to propose a novel method for estimation of central incisor width (CIW) and length (CIL) for Saudi population. Materials and methods:Extraoral and intraoral measurements were recorded for a total of 236 subjects. Descriptive statistical analysis and Pearson's correlation tests were performed. Association was evaluated between combined anterior teeth width (CATW) and interalar width (IAW), intercommisural width (ICoW) and interhamular notch distance (IHND) plus 10 mm. Evaluation of the linear relationship between central incisor length (CIL) with facial height (FH) and CIW with bizygomatic width (BZW) was also performed.Results: Significant correlation was found between the CATW and ICoW and IAW (p-values <0.0001); however, no correlation was found relative to IHND plus 10 mm (p-value = 0.456). Clinical significance: Based on the results of the study, ICoW and IAW measurements can be useful in estimating the initial reference value for CATW, while the proposed novel approach using specific palatal dimensions can be used for estimating the width and length of central incisors. These methods are crucial to obtain esthetic treatment results within the parameters of the given population.

Background Coronavirus disease-19 (COVID-19) is a recent pandemic that is advancing at a rapid rate. The future course of the disease includes severe respiratory infection and also leads to death if unattended. Meticulous measures are necessary before attending any patient. The dental operatories and the clinic surroundings must be well sanitized so as to prevent the spread of pandemic. Aim and objective This review discusses in brief about the pathophysiology and course of COVID-19. Further, we discussed in detail the management aspects of patients in periodontal perspective and the sanitization procedures required for the dental clinic. Review results The SARS coronavirus enters the human circulation via the angiotensin-converting enzyme (ACE) receptors which are also found on the oral mucosal surfaces. Furin and Cathepsin L are the pro-inflammatory molecules released during pathogenesis of periodontitis and mediate the molecular pathways that help the virus invade into the host. The clinic set-up should be modified to best suit the pandemic conditions. This includes the three phases, i.e., phase I: preparatory phase; phase II: implementation phase; and phase III: follow-up. The patient management is explained based on the emergency needs of the patient based on the recent AAP classification of periodontal diseases and conditions 2017 as emergency, urgent, and elective treatment needs which have been explained in detail. Conclusion It can be strongly concluded that there is direct relationship between oral health and systemic health. The treatment procedures and sanitization protocols must be definitely modified. Further consensus and systematic reviews help us arriving at a more standardized protocol. Clinical significance This review would help clinicians modify the way they treat patients in the clinic and provide better services depending upon the emergency needs of the patient.
