Global prevalence of gingival recession: A systematic review and meta-analysis.

OBJECTIVE: This systematic review and meta-analysis aimed to estimate the global prevalence of gingival recession (GR) in the general population. MATERIALS AND METHODS: Population-based observational studies reporting the prevalence of GR and published from 1991 to 2021 were identified from five electronic databases and manual searches. Risk of bias was assessed using the Joanna Briggs Institute's Critical Appraisal Checklist for Prevalence Studies. The pooled prevalence of GR was calculated by using a random-effect model. Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach was used to summarize the overall certainty of evidence. RESULTS: A total of 15 studies involving 37,460 participants were included. The overall pooled prevalence was 78.16% at the minimal reported threshold values and 84.92% at ≥1 mm "cut-off" with high heterogeneity among studies. A separate analysis for the buccal GR revealed a pooled prevalence of 75.42%. The risk of bias was found to be high for 10 and low for 5 studies. The overall certainty of the evidence was assessed to be very low. CONCLUSION: More than two-thirds of the population worldwide was found to be affected by GR. Studies with standard case definition and less heterogeneity are required to accurately estimate the prevalence of GR.

Economic Analysis of Delivering Postpartum Intrauterine Contraceptive Device Services in India.

INTRODUCTION: We estimated the unit costs for implementing postpartum intrauterine contraceptive device (PPIUCD) services from the perspective of both health system and development agencies. METHODOLOGY: Seven districts from two Indian states, i.e., Uttarakhand (UK) and Madhya Pradesh (MP), were selected to study the cost of PPIUCD service. Data on costs incurred both by health system and development agencies for PPIUCD service were collected. Unit costs were estimated for providing PPIUCD and IUCD services by state and district level of care in public health-care system. We also estimated unit cost per couple-year protected (CYP) by the level of the health facility. RESULTS: We found that the unit cost per PPIUCD insertion including all costs, i.e., for service delivery and program support, was INR 522 ($8.7) and INR 502 ($8.4) in MP and UK, respectively. Similarly, the unit costs per interval IUCD insertion were INR 287 ($4.8) in UK and INR 281 ($4.7) in MP. Development partners have a share of >50% in overall costs. From a health system's perspective, PPIUCD and interval IUCD cost per CYP at the level of district hospital were INR 440 ($7.3) and INR 449 ($7.5), respectively. CONCLUSIONS: In India, PPIUCD, being a low-cost procedure, should be considered as a primary strategy targeted toward pregnancy spacing over other contraceptory methods.
