Anomalies of Deciduous Teeth and Findings in Permanent Dentition

Prevalencija anomalija mliječnih zuba istraživana je u općoj populaciji predškolske djece Zagreba. Uzorak je sačinjavalo 2.987 djece u dobi od 3 do 6 godina (1.582 dječaka i 1.405 djevojčica). Utvrđena je hipodoncija mliječnih zuba od 0,47%, hiperdoncija od 0,10% i dvostruki zubi od 0,43% za cijeli uzorak. Ukupna prevalencija svih anomalija u uzorku iznosila je 1,0%. Uzorak za analizu stanja trajnih zuba bio je uvećan kliničkim uzorkom djece s istim anomalijama i iznosio je 48 djece. Djeci s anomalijama mliječnih zuba snimljeni su ortopantomogrami i analizirano je stanje trajne denticije. U djece s hipodoncijom mliječnih zuba nađena je hipodoncija u trajnoj denticiji u 100% slučajeva. Kod hiperdoncije mliječnih zuba, anomalije trajne denticije zapažene su u 85,7% slučajeva, dok su u djece s dvostrukim mliječnim zubima anomalije trajnih zuba bile zastupljene u 61,1% slučajeva. Hipodoncija mliječnih zuba nađena je u obje čeljusti u svega 8,7%, a u trajnoj denticiji u 34,8%. Simetrično pojavljivanje hipodoncije (tj. obostrano) bilo je značajno više u dječaka (u 56,3%) nego u djevojčica (u 28,6%) u mliječnoj denticiji. Simetričnost pojave hipodoncije značajno je viša u trajnoj denticiji nego u mliječnoj (81,3% u dječaka i 57,1% u djevojčica). Od mliječnih zuba hipodoncijom su najčešće zahvaćeni gornji lateralni sjekutići (u 48,8%) i donji središnji sjekutići (u 34,9%)). Hiperdoncija je nađena samo u dječaka i uvijek se radilo o prekobrojnom gornjem lateralnom sjekutiću. Anomalije mliječnih zuba pokazuju visok stupanj povezanosti s nalazom u trajnoj denticiji. Hipodoncija mliječnih zuba znači hipodonciju trajnih zuba u 1 0 0 %) slučajeva. Hiperdoncija mliječnog zuba znači rizik za anomaliju trajnih zuba od 85,7%, a dvostruki mliječni zubi znače mogućnost anomalije trajnih zuba u 61,1% slučajeva.Prevalence of anomalies o f deciduous teeth has been analyzed in the general population of Zagreb preschool children. The sample comprised 2.987 children from 3 to 6 years of age (1.582 boys and 1,405 girls). Hypodontia was found in 0,47%, hyperdontia in 0,10%, and double teeth in 0,43%) of total sample. Total prevalence of all anomalies in the sample was 1,0%. The sample for the analysis of permanent dentition has been enlarged with the clinical sample of children having the same anomalies and comprised 48 children. In all children with anomalies of primary teeth the orthopantomograms were taken and the status of permanent dentition was analyzed. In children with hypodontia in primary dentition hypodontia of permanent teeth was found in 100% of cases. Patients with hyperdontia of primary teeth displayed anomalies in permanent dentition in 85,7%, while in children with primary double teeth, anomalies ofpermanent teeth were present in 61,1% of cases. Missing deciduous teeth were found in both jaws in only 8,7% of cases, and in 34,8%) in permanent dentition. Symmetrical occurrence of hypodontia of primary teeth (i.e. in both sides of jaws) was significantly higher in boys (56,3%) than in girls (28,6%?). In permanent dentition symmetrical occurrence of hypodontia was significantly higher than in primary dentition (81,3% in boys and 57,1% in girls). The most frequently missing primary teeth were maxillary lateral incisors (48,8%)) followed by mandibular central incisors (34,9%)). Hyperdontia of primary teeth has been found only in boys, and it related only to the maxillary lateral incisors. Anomalies of deciduous teeth show a high degree of association with the finding in the permanent dentition. Hypodontia o f primary teeth indicate the hypodontia of permanent teeth in 100%) of cases. Children with hyperdontia of primary teeth have a risk for the anomaly of permanent teeth of 85,7%, while finding o f double deciduous teeth indicates to the possibility of anomaly o f permanent teeth in 61,1% of cases

A comparative analysis of oral health in mentally retarded and normal children

Ispitivanjem je utvrđena razlika u frekvenciji karijesa kod mentalno nedovoljno razvijene djece i zdrave, utjecaj MNR na intenzitet karijesa, razlika u broju zuba i korelacija »stupnja MNR i gingivoparodontnih oboljenja. Pregledano je 119 umjereno, teško i profundno mentalno nedovoljno razvijene djece. Utvrđeno je da postoji značajna razlika u prevalenciji karijesa kod teško mentalno nedovoljno razvijene i zdrave djece, intenzitet karijesa pada sa stupnjem MNR, hipodoncija raste s mentalnom nerazvijenošću, a također i oboljenja oralne sluznice.This study was undertaken to find the differences in the prevalence of caries between mentally retarded and normal children, as well as the effect of mental retardation on the severity of teeth and the correlation between the degree of mental retardation and gingivoperiodontal diseases. A group of 119 children with moderate, severe of profound mental retardation were examined. A significant difference in the prevalence of caries was recorded between a subgroup of severely retarded children and normal children. The severity of caries was found to decline, and hypodontia and oral mucosa diseases to increase with the degree of mental retardation

Double Teeth in Primary Dentition and Findings of Permanent Successors

U uzorku od 2.987 predškolske djece Zagreba utvrđena je prevalencija dvostrukih zuba od 0,5 posto. Od djece s dvostrukim zubima 60 posto su bile djevojčice, a 40 posto dječaci. U uzorku djece s dvostrukim zubima nađena je fuzija u 66,7% i geminacija u 33,3% slučajeva. Djeci s utvrđenim dvostrukim zubima snimljeni su ortopantomogrami. Njihovom analizom utvrđene su anomalije trajnih zuba u 53,3 posto djece s dvostrukim zubima. Djeca s geminacijom mliječnih zuba imala su anomaliju trajnih zuba u 20% slučajeva (hiperdoncija u svim slučajevima), dok je fuziju mliječnih zuba pratio abnormalan nalaz u trajnoj denticiji u 70% slučajeva (hipodoncija u svim slučajevima). Dobiveni rezultati ukazuju na potrebu distinkcije između različitih tipova dvostrukih zuba u mliječnoj denticiji, tj. između fuzije i geminacije jer vjerojatnost manjkanja trajnih nasljednika značajno ovisi o tipu anomalije.Prevalence of double teeth in primary dentidion of 0,5% was established in the sample of 2.987 preschool children of Zagreb. Between children with double teeth 60% were female and 40% males. Fusion ocured in 66,7 percent and gemination in 33,3 percent in the sample of children having double teeth. In all children with double teeth orthopantomograms were taken. Analysis of radiographs revealed anomalies of permanent successors in 53,3 percent of all children with double primary teeth. In children with gemination in primary dentition anomalies o f permanent teth were present in 20 percent (hyperdontia in all cases), while fusion of deciduous teeth was acompanied by abnormal finding (hypodontia) in permanent dentition in 70 percent. Obtained results pointed out to the need of distinction between type of double teeth in primary dentition, i. e. between fusion and gemination because chance of lacking the permanent successors is considerably dependant on the type of anomaly
