The purpose of the study was to localize the characteristic craniofacial abnormalities in young children with complete bilateral cleft lip and palate, to average their growth changes, and to compare all these to observations from a normative sample. A longitudinal sample of 30 males with complete bilateral cleft lip and palate was obtained from the files of the Craniofacial Center at The Hospital for Sick Children, Toronto. An age-matched noncleft control sample was selected from the Burlington Orthodontic Research Center. All individuals had lateral cephalometric radiographs at approximately 6 years, 12 years, and as adults. These were analyzed by cephalometrics and by tensor biometrics. The results of the two methods of analysis were in agreement and tended to complement each other. In the cleft sample, there was little cleftinig effect on the midline structures of the cranial base; the premaxilla was initially protruded but became normal in the adult; the nasal bone was longer and more protruded; the posterior maxillary segments were hypoplastic and the bony pharynx narrower; there was overeruption of the posterior teeth; and the mandibular gonial area was smaller.

To assess the craniofacial changes related to growth and/or to orthodontic and orthognathic treatments, it is necessary to superimpose serial radiographs on stable structures. However, conventional superimposition provides only a graphical illustration of these changes. To increase the precision of growth and treatment evaluations, it is desirable to quantitate these craniofacial changes. The aims of this study were to (1) evaluate a superimposition-based cephalometric method to process numerical data for craniofacial growth changes and (2) identify a valid, reliable, and feasible method for superimposition. Forty pairs of cephalograms were analyzed at T1 and T2 (mean age 9.9 and 15.0 years, respectively). The superimposition-based cephalometric method involved relating the sagittal and vertical measurements on the T2 radiographs to the nasion and sella landmarks on the T1 radiographs. Validity and reliability were evaluated for three superimposition methods: the sella-nasion (SN); the tuberculum sella-wing (TW); and Björk’s structural. Superimposition-based cephalometrics can be used to quantify craniofacial changes digitally. The numerical data from the superimposition-based cephalometrics reflected a graphical illustration of superimposition and differed significantly from the data acquired through conventional cephalometrics. Superimposition using the TW method is recommended as it is valid, reliable, and feasible.

Abstract Objective: To determine whether dentoalveolar changes or vertical condylar growth is more closely related to the true forward rotation of the mandible during the transition between the late primary and early mixed dentition stages of development. Materials and Methods: The sample included 50 subjects (25 males and 25 females) with Class I (N  =  25) and Class II (N  =  25) molar relationships. They were selected based on the availability of lateral cephalograms at two developmental stages: T1: last film with complete primary dentition (5.8 ± 0.4 years) and T2: first film with permanent incisors and permanent molars fully erupted (8.0 ± 0.2 years). Seventeen landmarks were identified and 22 measurements were calculated. The mandibles at T1 and T2 were superimposed using natural reference structures in order to measure true mandibular rotation. Results: The mandible underwent −2.4° ± 2.6° of true rotation, 1.9° ± 2.4° of remodeling, and −0.6° ± 1.8° of apparent rotation. There were no significant sex or Class differences in true rotation, remodeling, and apparent rotation. There was a moderate correlation (r  =  0.76) between true rotation and remodeling and a moderately low correlation (r  =  0.40) between true rotation and apparent rotation. There was a weak correlation between true rotation and SNA (r  =  0.28). True rotation was most closely associated with the increases in U1/S-N (r  =  −0.34), increases in U1/PP (r  =  −0.36), and decreases in Id-Me (r  =  0.36). Conclusions: Independent of sex and Class, the true mandibular rotation that occurred between the late primary and early mixed dentition was mostly masked by angular remodeling, resulting in limited amounts of apparent rotation. True rotation was significantly related to anterior dentoalveolar changes but not to the vertical growth changes that occurred.

Background: Although they are not life threatening, dental caries and periodontaldisease are the most predominant and widely spread oral diseases throughout theworld. The aims of the study included the investigation of the prevalence andseverity of dental caries, gingivitis and dental plaque in relation to gender,furthermore, nutritional status was assessed in relation to oral health condition(dental caries).Materials and Methods: This oral health survey was conducted among primaryschool children aged 9 years old in Dewanyiah city in Iraq. The total samplecomposed of 600 child (320 males and 280 females) selected randomly fromdifferent school in Dewanyiah city. Diagnosis of dental caries was according tothe criteria described by WHO (1987). Plaque index of Silness and Loe (1964)was used for plaque assessment, gingival index of Loe and Silness (1963) wasfollowed for recording gingival health condition. Nutritional status was assessedaccording to body mass index (BMI) indicator using anthropometric measurement(height and weight).Results: Results showed that the prevalence of dental caries was 85% for 9 year-oldschool children. Regarding primary and permanent dentition, dental caries washigher among females compared to males with statistically significant difference(P<0.05) for primary dentition, on the other hand, males showed higher values offilled surfaces compared to females with statistically significant difference(P<0.05) for primary dentition and highly significant difference (P<0.01) forpermanent dentition. Finding of this study revealed that 100% of the children hadgingival inflammation. Furthermore, the values of plaque and gingival indiceswere higher among males compared to females with statistically highly significantdifferences (P<0.01). In current study, the prevalence of malnutrition described bythe BMI indicator was 5.3%. For total samples no significant difference wasrecorded in dmfs /DMFS values among wasting and well nourished children(P>0.05).Conclusion: A high prevalence of dental caries and gingivitis were recorded.Improvement in the prevention educational programs is needed among schoolchildren.

Abstract: To determine the frequency and distributionof dental anomalies of shape and numberin primary dentition. Methods: The study is retro-prolective, crosssectionaland descriptive. The sample was probabilistic,stratified for convenience by gender. Theclinical record of 1,568 patients was reviewed.These patients attended the Clinic of PediatricDentistry of FEBUAP during the period of 2012-2014, only 720 records of patients were includedin the study (321 girls and 399 boys) between theages of 1-10 years old, who provided complete,crisp radiographic studies with the presence ofdental anomalies of shape or number, the studywas divided into active and inactive patients.For inactive patients, photographs of x-rays withdental anomalies of shape and/or number weretaken. For cases with active patients, an interviewwith one of the parents was conducted andauthorization with informed consent was requested,also the child agreed to do a clinical examinationand take intraoral photographs. Results:A total of 63 children had anomalies (17girls and 46 boys). The total prevalence of dentalanomalies was 9%, of which 3.1% were (fusedand geminated teeth), 1.1% (agenesis) and 1.9%(supernumerary), 1.3% (supernumerary roots),0.27% (macrodontia), 0.11% (microdontia), andfinally 0.27% corresponded to (talon cusp). Conclusions: Although the prevalence of theseanomalies is not high, it is important to do a routineradiographic examination for early diagnosisand accordingly apply the correct preventivemeasures to establish the best treatment plan.
