BACKGROUND AND OBJECTIVES: Various extraction protocols have been followed for successful orthodontic treatment. The purpose of this study was to evaluate the extraction protocols in patients who had previously undergone orthodontic treatment and also who had reported for continuing orthodontic treatment from other clinics.
MATERIALS AND METHODS: One hundred thirty eight patients who registered for orthodontic treatment at the Faculty of Dentistry were divided into 10 extraction protocols based on the Orthodontic treatment protocol given by Janson et al. and were evaluated for statistical significance.
RESULTS: The descriptive statistics of the study revealed a total of 40 (29%) patients in protocol 1, 43 (31.2%) in protocol 2, 18 (13%) in protocol 3, 16 (11.6%) in protocol 5, and 12 (8.7%) in Type 3 category of protocol 9. The Type 3 category in protocol 9 was statistically significant compared to other studies. Midline shift and collapse of the arch form were noticed in these individuals.
CONCLUSION: Extraction of permanent teeth such as canine and lateral incisors without rational reasons could have devastating consequences on the entire occlusion. The percentage of cases wherein extraction of permanent teeth in the crowded region was adopted as a treatment option instead of orthodontic treatment is still prevalent in dental practice. The shortage of orthodontists in Malaysia, the long waiting period, and lack of subjective need for orthodontic treatment at an earlier age group were the reasons for the patient's to choose extraction of the mal-aligned teeth such as the maxillary canine or maxillary lateral incisors.

Bimaxillary protrusion is a unique dentofacial deformity trait that can exist in an individual as an isolated problem or in combination with other skeletal and dental-related issues. Orthodontist and oral and maxillofacial surgeons are often the main primary team involved in the management of bimaxillary protrusion. Clinical dilemma often exists as cases can either be treated orthodontically or may require a combination of orthodontic and skeletal segmental orthognathic surgery. This article aims to help clinicians improve their approach to management of bimaxillary protrusion by creating a classification based on the severity that can guide treatment selection.

Fulltext Prevalence and factors related to malocclusion, normative and perceived orthodontic treatment need among children and adolescents in Bangladesh

Sultana S, Hossain Z

Dental Press J Orthod, 2019 Aug 01;24(3):44.e1-44.e9.

PMID: 31390447 DOI: 10.1590/2177-6709.24.3.44.e1-9.onl

OBJECTIVE: The purpose of the present study was to assess the prevalence of normative and perceived orthodontic treatment need in schoolchildren and adolescents, related risk factors, and children/parent's aesthetic perception, compared to orthodontist's opinion, in Dhaka city, Bangladesh.

METHODS: A random sample of 800 schoolchildren aging 11-15 years was selected from different schools in the city of Dhaka, Bangladesh. The Dental Health Component (DHC) and Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) were assessed as normative treatment need. The Decayed, Missing, Filled Teeth (DMFT) index was used to record caries experience. Children were interviewed on the perception of orthodontic treatment need. Parents also completed a questionnaire on the perception of their child's orthodontic treatment need, assessed by AC/ IOTN.

RESULTS: According to the DHC/IOTN, only 24.7% were in the category of definite need (grade 4-5) for orthodontic treatment. A significant difference was found between the clinician/children and clinician/parents perceived AC score of IOTN (p= 0.0001). Multiple logistic regression showed children with a higher DMFT were significantly more likely to need orthodontic treatment, according to the DHC of IOTN.

CONCLUSION: A low proportion of schoolchildren needs normative orthodontic treatment in the city of Dhaka, Bangladesh. Children with a higher DMFT score were significantly more likely to need orthodontic treatment, according to the DHC of IOTN.

Mohd Tahir N, Wan Hassan WN, Saub R

Eur J Orthod, 2019 08 08;41(4):370-380.

PMID: 30321319 DOI: 10.1093/ejo/cjy063

OBJECTIVES: The aim of this study was to compare vacuum-formed thermoplastic retainers (VFRs) constructed on stone models (VFR-CV) and those constructed on three-dimensional (3D) printed models (VFR-3D) based on patients' perspective and post-treatment stability.

STUDY DESIGN: The research was designed as a crossover, randomized control trial.

MATERIALS AND METHODS: Subjects comprised patients receiving fixed appliances at a teaching institution and indicated for VFRs. Post-treatment stone models were scanned with a structured-light scanner. A fused deposition modelling machine was used to construct acrylonitrile-butadiene-styrene (ABS)-based replicas from the 3D scanned images. VFRs were fabricated on the original stone and printed models. Analysis comprised independent t-tests and repeated measures analysis of variance.

RANDOMIZATION: Subjects were allocated to two groups using Latin squares methods and simple randomization. A week after debond, subjects received either VFR-CV first (group A) or VFR-3D first (group B) for 3 months, then the interventions were crossed over for another 3 months.

BLINDING: In this single-blinded study, subjects were assigned a blinding code for data entry; data were analysed by a third party.

OUTCOME MEASURES: The primary outcome measured was oral health-related quality of life (OHRQoL) based on Oral Health Impact Profile-14 (OHIP-14). Secondary outcome was post-treatment stability measured using Little's Irregularity Index (LII).

RESULTS: A total of 30 subjects (15 in each group) were recruited but 3 dropped out. Analysis included 13 subjects from group A and 14 subjects from group B. Group A showed an increase in LII (P < 0.05) after wearing VFR-CV and VFR-3D, whereas group B had no significant increase in LII after wearing both VFRs. Both groups reported significant improvement in OHRQoL after the first intervention but no significant differences after the second intervention. LII changes and OHIP-14 scores at T2 and T3 between groups, and overall between the retainers were not significantly different. No harm was reported during the study.

CONCLUSION: VFRs made on ABS-based 3D printed models showed no differences in terms of patients' OHRQoL and stability compared with conventionally made retainers.

PMID: 1885927

This case report illustrates the successful management of a case of mutilated maxillary incisors in a 13 year old patient through a sequence of therapy designed to closely coordinate the various disciplines, endodontics, restorative dentistry and orthodontics, involved. Endodontics was directed towards the control of the infected pulp, restorative treatment was to reconstruct the broken down teeth in stages which were essential in the sequence of treatment, and orthodontics was involved in the achievement of functional occlusion and alignment. The comprehensive treatment approach combined to achieve satisfactory aesthetics and function.

Objective: To audit the amount and complexity of case load and the waiting time for orthodontic treatment in Orthodontic Department of Universiti Kebangsaan Malaysia (UKM).
Materials and Methods: This study involved three waiting list records in Orthodontic department, UKM and 484 patients’ record were selected using Random Sampling technique. Demographic data of the patients were noted. Data on date of patient’s visit to ‘Klinik Rawatan Utama’ (KRU), Screening clinic and first orthodontic treatment (removable/fixed) clinics were also recorded. The severity of referred cases were graded using complexity scale (Russle et al, 1999).
Results: Patients were mostly female (76%) with age ranging from 10 to 52 years old. 75% of the referred cases were complex cases. From the year 2002-2007, 35% were referred for removable and 65% were referred for fixed clinic. In average, orthodontic screening waiting time was 6.9 ± 2.5 month. Patient would received removable and fixed appliance treatment after 4.4 ± 1.0 months and 14.5 ± 9.8 months respectively.
Conclusions: Most patients were referred to fixed waiting list. The waiting time from 2002 until 2007 for orthodontic treatment in UKM was longest for fixed followed by screening. The shortest waiting time was for the removable treatment.

Orthodontic treatment need in Asian adult males

Soh J, Sandham A

Angle Orthod, 2004 Dec;74(6):769-73.

PMID: 15673139

Orthodontic treatment in adults has gained social and professional acceptance in recent years. An assessment of orthodontic treatment need helps to identify individuals who will benefit from treatment and safeguard their interest. The purpose of this study was to assess the objective and subjective levels of orthodontic treatment need in a sample of orthodontically untreated adult Asian males. A sample of male army recruits (n = 339, age 17-22 years, Chinese = 258, Malay = 60, Indian = 21) with no history of orthodontic treatment or craniofacial anomalies participated in the study on a voluntary basis with informed consent. Impressions for study models were taken. Objective treatment need was assessed based on study model analysis using the Index of Orthodontic Treatment Need (IOTN). Questionnaires were used to assess subjective treatment need based on subjective esthetic component (EC) ratings. Fifty percentage of the sample had a definite need for orthodontic treatment (dental health component [DHC] grades 4 and 5), whereas 29.2% had a moderate need for treatment (DHC grades 3). The occlusal trait most commonly identified was dental crossbite. Malay males had the highest percentage with a definite need for treatment for both dental health and esthetic reasons in comparison with Chinese and Indian males. However, there was no difference in the level of treatment need among the ethnic groups (P > .05). No correlation between objective and subjective EC scores was found (P > .05). A high level of investigator-identified treatment need was not supported by a similar level of subject awareness among the adult sample.

Postnatal treatment factors affecting craniofacial morphology of unilateral cleft lip and palate (UCLP) patients in a Japanese population

Alam MK, Iida J, Sato Y, Kajii TS

Br J Oral Maxillofac Surg, 2013 Dec;51(8):e205-10.

PMID: 23099108 DOI: 10.1016/j.bjoms.2012.10.001

We have evaluated the craniofacial morphology of Japanese patients with unilateral cleft lip and palate (UCLP) and assessed the various postnatal factors that affect it. Lateral cephalograms of 140 subjects (mean (SD) aged 7 (2) years) with UCLP were taken before orthodontic treatment. Surgeons from Hokkaido University Hospital had done the primary operations. The craniofacial morphology was assessed by angular and linear cephalometric measurements. Cheiloplasty, palatoplasty, and preoperative orthopaedic treatment were chosen as postnatal factors. To compare the assessments of the postnatal factors, we made angular and linear cephalometric measurements for each subject and converted them into Z scores in relation to the mean (SD) of the two variables. Subjects treated by the modified Millard cheiloplasty had larger sella-nasion-point A (SNA) and nasion-point A-pogonion (NA-POG) measurements than subjects treated by the modified Millard with a vomer flap cheiloplasty. Two-stage palatoplasty showed consistently better craniofacial morphology than the other palatoplasty. Subjects who had preoperative orthopaedic treatment with a Hotz plate had significantly larger upper incisor/sella-nasion (U1-SN) measurements than who had no preoperative orthopaedic treatment or an active plate. We conclude that in subjects treated by a modified Millard type of cheiloplasty, a two-stage palatoplasty, and a Hotz plate there were fewer adverse effects on craniofacial morphology.
