Digital versus Manual Tracing in Cephalometric Analysis: A Systematic Review and Meta-Analysis.

Background: Over the years, various researchers have attempted to compare digital cephalometry with the conventional manual approach. There is a need to comprehensively analyze the findings from the earlier studies and determine the potential advantages and limitations of each method. The present systematic review aimed to compare the accuracy of digital and manual tracing in cephalometric analysis for the identification of skeletal and dental landmarks. Methods: A systematic search was performed using the keywords "Digital" AND "Manual" AND "Cephalometry" to identify relevant studies published in the English language in the past decade. The electronic data resources consulted for the elaborate search included the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, CINAHL, EMBASE, PsycINFO, Scopus, ERIC, and ScienceDirect with controlled vocabulary and free text terms. Results: A total of n = 20 studies were identified that fulfilled the inclusion and exclusion criteria within the timeframe of 2013 to 2023. The data extracted from the included articles and corresponding meta-analyses are presented in the text. Conclusions: The findings of the present systematic review and meta-analysis revealed trends suggesting that digital tracing may offer reliable measurements for specific cephalometric parameters efficiently and accurately. Orthodontists must consider the potential benefits of digital cephalometry, including time-saving and user-friendliness.

Comparison of Autologous Blood Injection and Dextrose Prolotherapy in the Treatment of Chronic Recurrent Temporomandibular Dislocation: A Randomized Clinical Trial.

Introduction: Prolotherapy is a minimally invasive technique that aims to functionally restore or repair the soft and hard tissues of the TMJ by injecting a stimulant. The present study was conducted to compare the effectiveness of dextrose and autologous blood injection (ABI) as prolotherapy agents in the treatment of patients with chronic recurrent TMJ dislocation (CRTD). Materials and Method: Thirty-two patients were divided into two groups-ABI and dextrose (n = 16 each). The superior joint space was located by means of cantho-tragal line and lavage. Delivery of prolotherapy agent was performed by single-needle technique. An elastic bandage was applied for a week and rehabilitation was initiated three weeks after the treatment. Pain level, joint hypermobility, maximal mouth opening, and frequency of dislocations were recorded at various follow-up intervals up to one year post-treatment. Results: No significant difference (p > 0.05) was seen for the values between both groups at all time intervals in the pain level. At the 6-month and annual follow-ups, the mouth opening of the patients treated with ABI was significantly lower (p < 0.01) as compared to those treated with dextrose. The patients treated with ABI therapy exhibited fewer dislocations (p < 0.05) within the following year. Conclusion: Prolotherapy is a relatively noninvasive, safer, and effective treatment modality with a high success rate for patients with CRTD. Both, ABI and dextrose, proved effective in reducing the pain and joint hypermobility associated with CTRDs within a week. ABI proved to be more efficient in reducing the mouth opening and limiting the dislocation of TMJ as compared to dextrose therapy.

Protocols in the management of cleft lip and palate: A systematic review.

AIM: To identify clinical decisions on surgical as well as non-surgical modalities for the treatment of CLP patients based on randomized controlled trials (RCTs). MATERIALS AND METHODS: PubMed, Ebscohost, and Cochrane Library were searched and 20 articles based on RCTs conducted on cleft patient management were identified. RESULTS: The topics explored were infant orthopedics, lip and palate repair, alveolar bone grafting, and management of cleft maxillary hypoplasia. Nasoalveolar molding (NAM) was found to have great benefits when carried out within one month of birth. Fisher and Mohler's lip repair technique and use of recombinant human bone morphogenetic protein-2 (rh-BMP2) for alveolar bone grafting showed promising results. rh-BMP2 for alveolar bone grafting appears to be a promising alternative to autografts. CONCLUSION: Early commencement of NAM in neonatal life is of great benefit to cleft patients. There is a need for more multicentre collaborations, mainly to identify the ideal surgical technique to reduce the variability in treatment and to ensure that the patient receives appropriate evidence-based treatment.

Toward developing natural histologic stains using anthocyanins: A novel approach.

INTRODUCTION: In the present-day scenario, wherein histotechnological laboratory personnel come into contact with numerous hazardous chemicals every day, laboratories are emphasizing on development of safer and environment-friendly alternatives globally which are easily available and feasible. In this context, we have attempted to utilize anthocyanins, a family of pigments naturally occurring in fruits and flowers and which are already used as natural food colorants, for assessing their utility as histological stains. MATERIALS AND METHODS: Juices of thin consistency from well-ripened pomegranates were obtained by using a juicer with blender functions. Formalin-fixed paraffin-embedded 4 µm thin sections were immersed in this solution for 2 h, during which the solution was periodically monitored. Several modifications were attempted such as the addition of Citrus limon (lemon) extract or acetic acid, change in orientation of the slides and refrigeration of the solution during the staining procedure. RESULTS: A peculiar pattern of reasonably diagnostic staining was observed in which the basal and suprabasal cells, basement membrane, inflammatory cells and collagen fibers stained prominently with a magenta color. The addition of lemon, horizontal orientation of slides and refrigeration each separately led to an improvement in staining characteristics. The addition of 4% acetic acid and refrigeration of the solution each led to an improvement in longevity of the staining solution. CONCLUSION: Anthocyanins could potentially be used as viable histological stains having advantages of availability, feasibility, color stability and nontoxicity, although numerous modifications to improve longevity of staining solution and staining characteristics are warranted by further research for which the present study could serve as a pretext.
