Comparison of anthropometric measurements as substitutes for McNamara’s cephalometric maxillomandibular unit measurements
F. Mojtahedzadeh, S. Alizadeh,
Volume 24, Issue 2 (23 2011)
Abstract

Background and Aims: Cephalometric measurements cannot be performed for screening purposes, therefore orthodontists usually have to use either photographic or anthropometric measurements in such occasions. Finding a valid and reliable alternative could be of great value. The purpose of this study was to evaluate the correlation between McNamara's cephalometric unit difference and a proposed soft tissue equivalent.
Materials and Methods: An anthropometric ruler was redesigned and used in this study. Soft tissue measurements were performed on 36 randomly selected specimens by two investigators. The soft tissue measurements included external auditory meatus to subnasale (Ext-Sn), external auditory meatus to soft tissue pogonion (Ext-Pog), and the difference between them (UDMA´). These measurements were considered as equivalents to cephalometric indices in McNamara's anteroposterior measurements, including maxillary (Co-A) and mandibular (Co-Gn) unit length and their difference (UDMA), respectively.
Results: All soft tissue variables had an intra-class correlation coefficient (ICC) above 0.90. There was a high and significant correlation between cephalometric and anthropometric measurements (P<0.01). The ICC between (Ext-Sn) and (Co-A) was 0.890, 0.869 between (Ext-Pog) and (Co-Gn), and 0.819 between UDMA´ and UDMA.
Conclusion: The proposed anthropometric method showed a good correlation with cephalometric equivalents and the results show that this method could be used for screening purposes, especially when a low-cost, non-invasive method is required. However it cannot be considered as a substitute for cephalometry in diagnostic and treatment purposes.

Abstract

Background and Aims: There is an increased risk of periodontal diseases in patients undergoing fixed orthodontic treatment. Chlorhexidine (CHX) is frequently used to promote oral hygiene; however, it is associated with several complications. Herbal mouthwashes can be used as the substitute without having similar complications. The aim the present study was to compare the effects of herbal mouthwashes (Matrica and Persica) with CHX 0.2% on the periodontal parameters of patients under fixed orthodontic treatment.

Materials and Methods: In a double-blind randomized clinical trial, 84 patients under fix orthodontic treatment were selected. After receiving oral hygiene instruction, the patients were randomly assigned to four groups (group 1: Matrica, group 2: Persica, group 3: CHX 0.02%, group 4: normal saline). Dental plaque scores (PI), gingival inflammation (GI) and papillary bleeding (PBI) indices were measured at the beginning, 1 week after receiving oral hygiene instructions and 30 days after mouthwash consumption. The scores of the periodontal indices were statistically analyzed by Kruskal Wallis, ANOVA the paired Mann-whitney U test and Tukey test.

Results: All of the indices were significantly reduced in study groups (except for the control). Matrica and Persica mouthwashes were similarly effective in improving the periodontal parameters. Their efficacy in decreasing the PBI scores was significantly higher than CHX 0.2% (P<0.01).

Conclusion: Application of the two herbal mouthwashes was effective in improving the periodontal parameters in patients undergoing fixed orthodontic treatment.
