PMID: 33944974 DOI: 10.1007/s00056-021-00301-6

PURPOSE: To determine the effect of WhatsApp (Facebook Inc., Menlo Park, CA, USA) and electronic mail reminders on oral hygiene compliance of orthodontic patients.
METHODS: A randomized, parallel group, double blinded study was conducted on 54 patients undergoing orthodontic treatment at a university clinic. They were randomized to 3 groups, i.e., WhatsApp (W) group, electronic mail (email) (E) group and control (C) group with 18 subjects in each group. Group (W) and group (E) received oral health messages once a week through WhatsApp and email reminders, respectively, while group (C) did not receive any reminders. Plaque was measured at baseline (T0), after 4 weeks (T1), and after 8 weeks (T2). For each subject, intraoral photographs were taken after application of a plaque-disclosing agent; and the area covered by plaque was measured on teeth 12, 13, 43, 22, 23 and 33 by planimetry. Data were analyzed using SPSS (version 22, IBM Corp., Armonk, NY, USA). Mixed analysis of variance (ANOVA) was used to compare plaque scores between and within the groups.
RESULTS: A total of 54 subjects (14 males and 40 females) with mean age of 22.43 years completed the study. At the end of 8 weeks, no statistically significant difference in the mean plaque score was found between the groups at the different time intervals (p = 0.201).
CONCLUSION: WhatsApp and email reminders did not significantly influence the oral hygiene compliance of orthodontic patients.

Objective: To determine the prevalence of bimaxillary protrusion in general and the prevalence of skeletal Class I and dental Class I bimaxillary protrusion/ proclination among orthodontic patients attending postgraduate orthodontic clinic at Faculty of Dentistry, Universiti Teknologi MARA (UiTM), Sungai Buloh, Malaysia. Materials and Methods: This is a cross sectional study which was carried out in two stages. The first part involves a random selection of 100 extra-oral profile photographs taken from postgraduate orthodontic residents’ patient list. The photographs were taken using Canon digital SLR camera EOS 70D with macro lens EF 100mm (Canon Inc., Tokyo, Japan) with patients in natural head position. The photographs were visually analysed for its bimaxillary protrusion features by two operators. The second part comprises of analyses of extra-oral profile photographs as well as intra-oral photographs of right buccal segment view which was conducted in two separate sittings. In the first sitting, five assessors analysed 259 extra - and intra-oral photographs followed by 40 photographs assessed in the second sitting for skeletal and dental Class I bimaxillary protrusion/ proclination. Statistical analysis for Kappa score was performed to assess the agreement between assessors using SPSS version 23 and Stata version 13. Results: The first part of the study showed an average prevalence of 34% with bimaxillary protrusion in 100 orthodontic patients. Whilst in the second part, prevalence of skeletal and dental Class I bimax ranging from 28 -33 per cent and 38-40 per cent respectively with very good and good inter-reliability agreement for both component. Conclusion: The prevalence of bimaxillary protrusion in general among UiTM orthodontic patients was found to range from 31 per cent to 37 per cent. Whilst the prevalence of skeletal and dental Class I bimax ranging from 28-33 per cent and 38-40 per cent respectively.

Relationship of maxillary incisors in complete dentures to the incisive papilla

PMID: 22790408

We investigated the relationship of the maxillary central incisors to the incisive papilla in wearers of complete dentures. First, image analyzer software was used to examine the relationship of the midpoint of the incisive papilla to the labial surface of the maxillary central incisors on occlusal photographs of 120 maxillary casts from dentate Malaysian adults. Then, an Alma denture gauge was used to identify the position of the labial surface of the maxillary central incisors in relation to the midpoint of the incisive papilla in complete dentures from 51 patients who requested replacement dentures at the Faculty of Dentistry, University of Malaya. The mean incisor distance to the incisive papilla in dentate adults was 9.59 ± 1.00 mm, while the mean incisor distance to the incisive papilla in complete dentures was 6.34 ± 1.87 mm. Thus, in our sample of edentulous patients, the anterior teeth in complete dentures were positioned approximately 3 mm closer to the incisive papilla, as compared with the position of the central incisors in natural dentition, and did not duplicate the position of the natural anterior teeth.

Smile attractiveness related to buccal corridor space in 3 different facial types: A perception of 3 ethnic groups of Malaysians

Nimbalkar S, Oh YY, Mok RY, Tioh JY, Yew KJ, Patil PG

J Prosthet Dent, 2018 Aug;120(2):252-256.
PMID: 29551374 DOI: 10.1016/j.prosdent.2017.10.021

STATEMENT OF PROBLEM: Buccal corridor space and its variations greatly influence smile attractiveness. Facial types are different for different ethnic populations, and so is smile attractiveness. The subjective perception of smile attractiveness of different populations may vary in regard to different buccal corridor spaces and facial patterns.
PURPOSE: The purpose of this study was to determine esthetic perceptions of the Malaysian population regarding the width of buccal corridor spaces and their effect on smile esthetics in individuals with short, normal, and long faces.
MATERIAL AND METHODS: The image of a smiling individual with a mesofacial face was modified to create 2 different facial types (brachyfacial and dolicofacial). Each face form was further modified into 5 different buccal corridors (2%, 10%, 15%, 22%, and 28%). The images were submitted to 3 different ethnic groups of evaluators (Chinese, Malay, Indian; 100 each), ranging between 17 and 21 years of age. A visual analog scale (50 mm in length) was used for assessment. The scores given to each image were compared with the Kruskal-Wallis test, and pairwise comparison was performed using the Mann-Whitney U test (α=.05).
RESULTS: All 3 groups of evaluators could distinguish gradations of dark spaces in the buccal corridor at 2%, 10%, and 28%. Statistically significant differences were observed among 3 groups of evaluators in esthetic perception when pairwise comparisons were performed. A 15% buccal corridor was found to score esthetically equally within 3 face types by all 3 groups of evaluators. The Indian population was more critical in evaluation than the Chinese or Malay populations. In a pairwise comparison, more significant differences were found between long and short faces and the normal face; the normal face was compared with long and short faces separately.
CONCLUSIONS: The width of the buccal corridor space influences smile attractiveness in different facial types. A medium buccal corridor (15%) is the esthetic characteristic preferred by all groups of evaluators in short, normal, and long face types.
